A recent study presented at the 2026 Lunar and Planetary Science Conference (LPSC) takes a closer look at that possibility. Researchers from The Johns Hopkins University Applied Physics Laboratory (JHUAPL) and Sandia National Laboratories used the “Venus Life Equation” (VLE), a framework developed by Noam Izenberg et al. in 2021, to estimate how material from Earth could introduce life into Venus’ atmosphere. Their modeling suggests that life delivered from Earth could potentially survive in Venus’ clouds for at least a few days per century.

The Venus Life Equation

Like the famous Drake Equation, the VLE estimates the probability of life by combining several contributing factors. Each factor is multiplied together to produce an overall estimate of the likelihood that life exists.

*### L = O x R x C*

In this equation, L represents the likelihood of Extant Life (0 to 1, where 0 is no chance and 1 is certainty). O stands for origination (the chance life began and became established on Venus), R represents Robustness (the ability of a biosphere to survive and adapt to changing conditions), and C refers to Continuity (The chance that habitable conditions persisted until today). Before applying this framework, the researchers first examined whether organic material could survive the journey from one planet to another, regardless of where it originally formed.

Surviving the Journey to Venus

Material blasted into space by an impact must endure enormous challenges. In addition to the violent shock of ejection, it is exposed to intense heat, the vacuum of space, radiation, and extreme temperature swings. Previous computer simulations and analyses of meteorites found on Earth have shown that organic material can survive both ejection from a planet and the trip through interplanetary space. Once it reaches Venus, however, that material would also need to remain suspended within or above the planet’s cloud layers in order to survive.

To investigate this, the team modeled how fireball meteorites (bolides) behave as they enter Venus’ atmosphere, including their ablation, explosion, and breakup into smaller fragments capable of remaining in the clouds. They relied on the “pancake model,” a widely used semi-analytic approach that describes how a bolide fragments while passing through an atmosphere. After the bolide explodes in the atmosphere (an “airburst”), aerodynamic drag spreads the fragments outward into a flattened “pancake” of material that the researchers describe as “cells.”

Billions of Potential Transfers

Using the pancake model together with values derived from earlier studies, the researchers estimated how many bolides from Earth or Mars could have reached Venus’ clouds. Their calculations suggest that hundreds of billions of cells may have been delivered from Earth to Venus, with hundreds of billions potentially remaining viable. Their preferred estimate indicates that about 100 cells become dispersed throughout Venus’ clouds each Earth year. Over the past 1 billion years, roughly 20 billion cells may have been transferred from Earth.

The researchers emphasize that their model does not capture every aspect of how bolides interact with Venus’ atmosphere. They also note that every parameter in the VLE carries significant uncertainty, much like the Drake Equation. Even so, their findings support the possibility that panspermia between Earth and Venus could occur. If a future astrobiology mission discovers life in Venus’ clouds, one possible explanation is that it originally came from Earth.

On July 2, 2025, the China-led Einstein Probe (EP) space telescope spotted an exceptionally bright X-ray source during a routine survey of the sky. The object’s brightness changed rapidly, making it immediately stand out from typical cosmic X-ray sources. The unusual detection prompted observatories around the world to begin follow-up observations.

The research was coordinated by the EP Science Center at the National Astronomical Observatories, Chinese Academy of Sciences (NAOC), with scientists from research institutions in China and several other countries contributing to the effort. Researchers from the Department of Physics at The University of Hong Kong (HKU), who are key members of the Einstein Probe scientific collaboration, helped interpret the observations. Their analysis suggests the event may represent an intermediate-mass black hole tearing apart and consuming a white dwarf star. If confirmed, it would provide the first direct observational evidence of this type of black hole feeding event. The results were published as the cover article in Science Bulletin.

Einstein Probe Detects an Unusual Cosmic Explosion

The discovery relied on the Einstein Probe’s two complementary X-ray instruments.

During its routine survey on July 2, 2025, the mission’s Wide-field X-ray Telescope (WXT), which combines advanced lobster-eye micro-pore optics with a very wide field of view and high sensitivity, detected a rapidly changing X-ray source that was later designated EP250702a (also known as GRB 250702B). At nearly the same time, NASA’s Fermi Gamma-ray Space Telescope detected several gamma-ray bursts coming from the same region of the sky.

Scientists realized the event was far more unusual after reviewing earlier WXT observations. The telescope had already detected steady X-ray emission from the same location roughly a day before the gamma-ray bursts appeared, a sequence rarely associated with powerful cosmic explosions. Around 15 hours after the initial detection, the source erupted into a series of intense X-ray flares. At its brightest, it reached a luminosity of approximately 3 × 10⁴⁹ erg s^-1, making it one of the brightest instantaneous outbursts ever recorded in the Universe.

“This early X-ray signal is crucial,” said Dr. Dongyue Li, first author of the paper from the National Astronomical Observatories of China. “It tells us this was not an ordinary gamma-ray burst.”

Rare X-Ray Signal Points to a Black Hole Feeding Event

Using the precise location measured by WXT, astronomers quickly directed major telescopes around the world toward the source. Observations across multiple wavelengths confirmed that the object was located on the outskirts of a distant galaxy. The Einstein Probe’s second instrument, the Follow-up X-ray Telescope (FXT), then monitored the event as it evolved.

Over roughly 20 days, the object’s brightness faded by more than a factor of 100,000. During that time, its X-ray emission also shifted from higher-energy (“hard”) X-rays to lower-energy (“soft”) X-rays.

After combining Einstein Probe observations with data collected across the electromagnetic spectrum, researchers found that EP250702a displayed several characteristics that existing models struggled to explain. Its X-ray emission began before the gamma-ray burst, it reached extraordinary brightness, evolved unusually quickly, and occurred in the outer region of its host galaxy instead of near the galaxy’s center, a combination that is rarely seen in known high-energy cosmic events. After evaluating multiple possible explanations, one scenario emerged as the strongest candidate: an intermediate-mass black hole tearing apart and consuming a white dwarf star.

In 2026, it is 100 years since George Minot and William Murphy reported that a liver-rich diet could treat pernicious anemia, then a frequently fatal disease. Their work transformed medicine and eventually led scientists to identify vitamin B12 as the substance in liver that treated the disease.

But the route to that breakthrough began with an unexpected clue from animal experiments. The American physician and pathologist George Whipple had shown that liver helped dogs recover from anemia caused by blood loss. Blood-loss anemia happens when the body loses red blood cells through bleeding. Pernicious anemia is different: the problem is not bleeding, but poor absorption of vitamin B12. Even so, Whipple’s experiments pointed researchers towards liver as a source of a powerful blood-forming factor.

Patients with pernicious anemia who had been close to death often improved dramatically within weeks of eating liver-rich diets. The success of liver treatment eventually led scientists to isolate the deep red compound now known as vitamin B12, or cobalamin.

Often mistaken

Despite decades of research, vitamin B12 deficiency remains common, particularly among older adults, vegans, vegetarians and people with conditions that affect absorption. Some people do not consume enough B12 because it is naturally found mainly in foods from animals, including meat, fish, eggs and dairy products. Others struggle to absorb it properly.

This becomes more common with age. Some older people produce less stomach acid, which is needed to release B12 from food. Others develop autoimmune gastritis, in which the immune system damages stomach cells involved in producing acid and intrinsic factor, the protein needed for vitamin B12 absorption. Weight-loss surgery and some medicines used for diabetes or acid reflux can also reduce absorption.

The symptoms of deficiency can develop slowly and are often mistaken for normal ageing. People may feel exhausted, weak or short of breath. Some develop numbness or tingling in their hands and feet, poor balance, memory problems or what many describe as “brain fog”. These symptoms are not specific to B12 deficiency, so persistent tiredness, tingling or balance problems should be checked rather than assumed to be a simple vitamin problem.

People at higher risk, including vegans, vegetarians, older adults and those taking medicines that affect stomach acid or diabetes treatment, may need testing or supplementation advice from a health professional.

Doctors have traditionally linked tiredness in B12 deficiency to anemia. Without enough vitamin B12, the bone marrow cannot produce healthy red blood cells. Instead, it releases unusually large and immature cells that carry oxygen less effectively around the body.

But anemia may not be the only reason people with low B12 feel exhausted.

Low energy

In humans, vitamin B12 is directly needed by only two enzymes, the proteins that help chemical reactions happen in the body. One helps the body make DNA, which cells need when they divide. The other helps mitochondria process certain fats and protein building blocks. Mitochondria are the tiny structures inside cells that help turn food into usable energy.

This mitochondrial role has attracted growing interest from researchers studying ageing, muscle function and vitamin B12 status. A 2026 study explored what happens when cells do not have enough B12. Researchers found that low B12 could interfere with the DNA inside mitochondria and reduce energy production in laboratory models of skeletal muscle (muscle cells studied outside the human body).

A related study in aged female mice found that B12 supplementation improved several signs of mitochondrial health in muscle, including the number and structure of mitochondria. Together, this work points to one possible reason why some people with low B12 report fatigue before obvious anemia is detected.

These findings do not mean vitamin B12 supplements can reverse ageing or act as an energy booster for people whose B12 levels are already normal.

Scientists have suspected a link between B12 and mitochondrial function for many years, because one of the two B12-dependent enzymes works inside mitochondria. Earlier research has also suggested that low B12 status may be linked with poorer muscle function in older adults, although much of this work is observational and cannot prove cause and effect.

So if you’re feeling persistently tired, is it worth paying for vitamin B12 injections at a wellness clinic or medispa? For most people, no. B12 injections are an established treatment for diagnosed deficiency, particularly when absorption is impaired, and the NHS uses hydroxocobalamin injections for vitamin B12 deficiency anemia.

But there is little evidence that B12 shots boost energy, weight loss or performance in people whose B12 levels are already normal. The more useful first step is to find out what is causing the tiredness.

The story of vitamin B12 is unusual because the body needs so little of it, yet the consequences of deficiency can be profound. Long before scientists understood its chemistry, doctors recognized that something in liver could restore strength, appetite and vitality to desperately ill patients.

A century later, researchers are still finding that this tiny cobalt-containing molecule does more than prevent anemia. It may also help explain how cells maintain energy and function as the body ages.

The study, published in the International Journal of Clinical and Health Psychology, was led by Diletta Barbiani, Alessandro Antonietti, and Francesco Pagnini. It was supported by PNRR grants through the Age-IT project.

“The study is part of an established line of research in which we analyze the role of the mind in aging processes, which is very important,” says Pagnini, Full Professor of Clinical Psychology at the Faculty of Psychology of the Università Cattolica.

Testing the Placebo Effect in Healthy Aging

Until now, no research had investigated whether a traditional placebo could influence abilities that naturally decline with age.

“Our goal,” Professor Pagnini explains, “was to clarify whether an open-label placebo therapy (i.e., where the recipient is aware it is a placebo) or a fake supplement (people don’t know it’s a placebo) could influence psychological, cognitive, and physical functions in older adults living in the community.”

To explore that question, the researchers recruited 90 healthy older adults and randomly assigned them to one of three groups. One group received no treatment at all. A second group received placebo pills but was told the pills contained active ingredients designed to improve well-being and physical function. The third group received the same inactive pills but was openly informed that the pills were placebos that could still trigger beneficial mind-body responses.

Before and after the three-week study, participants completed questionnaires (providing information on levels of perceived stress, psychological well-being, sleepiness, fatigue, optimism, self-efficacy, and stereotypes about aging). They also took objective tests measuring short-term memory, selective attention, and physical performance.

Memory, Stress, and Physical Performance Improved

After three weeks, the participants who knowingly took placebo pills experienced lower stress levels than both the deceptive placebo group and the control group. They also showed significant improvements in short-term memory compared with those who received no intervention.

Overall, both placebo groups experienced gains in cognitive and physical performance, although the strongest improvements were generally seen among participants who knew they were taking a placebo.

Physical performance increased by 7% in the deceptive placebo group and by 9.2% in the open-label placebo group. Cognitive performance also improved. Depending on the specific test, scores increased by between 12.6% and 14.6% among participants who believed they were taking a real supplement, while those who knowingly took a placebo improved by between 6.9% and 21.5%.

“These are significant effects,” the psychologist emphasizes, “comparable to those seen in some experimental studies on physical activity regarding physical performance and cognitive training, especially with regard to memory.”

Researchers also observed reductions in drowsiness. Stress levels improved most noticeably among participants who were aware they were taking a placebo.

A New Approach to Healthy Aging?

The findings suggest that placebo treatments can improve several aspects of functioning in older adults, with open-label placebos performing as well as, or in some cases better than, deceptive placebos.

According to the researchers, this makes open-label placebos a promising and ethically acceptable strategy for supporting healthy aging.

Professor Pagnini says the results add to growing scientific evidence that the mind plays an important role in the aging process. Thoughts, emotions, and self-perception may influence not only psychological well-being but also physical abilities and cognitive function, highlighting the powerful connection between the mind and the body.

“It’s really important that it has institutional continuity,” said Benjamin Anderson, associate professor of history of art and visual studies in the College of Arts and Sciences. “Many of us know and have been mentored by colleagues of the previous generation of excavators. As a result, it’s one of the few long-term archaeological projects in the region that has generated a critical mass of data.”

For the past several years, Anderson has focused on documenting the walls and buildings of Sardis’ acropolis, which became an important center during the Byzantine period after Roman rule.

“This is a city that shows up in lots of ancient historical sources,” he said. “But now, just in the last 75 years or so, we have the possibility of telling that story, also, through what the project has found archaeologically.”

This summer marked another milestone. Thanks to decades of excavation and the support of the local community, Sardis was added to the UNESCO World Heritage List.

“The opportunity to really start understanding a culture through the material remains is pretty unusual, and it requires that kind of long-term commitment,” Anderson said. “That’s also what’s being celebrated by the World Heritage designation by UNESCO. This project has always been distinguished from the very beginning by a desire to communicate results and to make their work legible to tourists and to locals and all manner of different audiences.”

Sardis Preserves Thousands of Years of History

Once the capital of the Iron Age kingdom of Lydia, Sardis occupied a strategic location between the Mediterranean and the Anatolian plateau. According to Annetta Alexandridis, associate professor of the history of art and classics in A&S, it served as “a place of cultural encounter between the East and West.”

The Lydian era remains especially significant to archaeologists and historians. The Lydians are widely credited with inventing coinage, and their ruler, King Croesus, became legendary for his immense wealth. Alexander the Great later conquered Lydia, after which Sardis became part of the Roman Empire, followed by the Byzantine and Ottoman empires.

“Because it was not over built by a modern city — it’s only a little village — Sardis gives you a really long history, from the Bronze Age, third millennium BCE, to basically today,” Alexandridis said. “These layers are all there, and make it sometimes difficult to excavate, because they are not clearly stratified. They interfere with each other, but, in a way, it’s an ongoing history, and that makes it so fascinating for us.”

As associate director of the excavation, Alexandridis studies Roman funerary culture and is now leading a survey of Sardis’ cemeteries, many of which have received far less attention than the nearby Bin Tepe cemetery, located about 10 kilometers north of the city. Bin Tepe contains some of the largest tumuli (burial mounds) ever recorded.

A Site That Shaped Archaeology

Sardis also occupies an important place in the history of American archaeology. The first modern excavation, led by the American Society for the Excavation of Sardis in the early 20th century, was “a really large-scale exploitation,” Alexandridis said. Excavators uncovered the Temple of Artemis and the necropolis, but many artifacts were damaged, disappeared, or were taken to the United States through questionable means. Among them was a massive column that remains on display at the Metropolitan Museum of Art.

The project ended with the Greco-Turkish War in the early 1920s. Over the following decades, some artifacts gradually made their way back to Turkey.

“It’s one of the first cases where we can see the whole discussion about restitution of antiquities that were illegally exported, until some were returned to Turkey,” Alexandridis said. “It has all of these broader issues of how to deal with cultural heritage from a not only preservation or scholarly point of view, but also political and legal, and of the question of stewardship and responsibility for culture in the past.”

The modern Harvard Cornell partnership began in 1958 under Harvard archaeologist George M. A. Hanfmann and Cornell architect Henry Detweiler from the College of Architecture, Art and Planning, whose expertise centered on documenting historic buildings.

“If you went to Sardis in 1950 there were a few things kind of sticking up above ground, but there was nothing really to see, per se,” Anderson said. “The architects were the first generation of Cornellians who were there, and the project really committed to taking what they’d excavated responsibly, supplementing it through newly manufactured pieces, and presenting a total experience of the structure, instead of just producing a drawing and putting it in a publication.”

During the 1950s and 1960s, the team reconstructed a monumental bath gymnasium complex and the largest synagogue in the ancient world. Those restoration efforts became influential models for similar work at archaeological sites elsewhere.

Since then, excavations have uncovered mud brick city walls, the acropolis, a Persian period garbage pit, a gold refining workshop, an ancient shopping district, and, most recently, a sanctuary plaza that required 15 years of excavation.

Training the Next Generation of Archaeologists

Today, the project is based at the Harvard Art Museums and includes researchers from Turkish institutions as well as several American universities, including the University of Wisconsin, Madison and the University of California, Berkeley. Cornell primarily contributes graduate students, along with an increasing number of undergraduates, who spend 10 weeks each summer working at the site.

Students either catalog recovered artifacts, most of which are ceramics, or “broken pots,” as Anderson described them, or supervise excavation trenches.

Because Sardis sits on an alluvial plain, some trenches extend as much as 12 meters underground.

“[They’re] quite terrifying in their own right,” Anderson said.

“Local workers, who are already trained, gradually remove the soil, and the students are there observing, documenting, taking notes, asking questions, determining when they need to stop and call in maybe the director or an associate director to take a look at what’s coming up, when they should take a photograph, when they should bring in the architects to make a state drawing of a particular moment,” Anderson said.

According to Anderson, Sardis is one of only three excavation projects worldwide that “most people who go on to a career in classical archaeology in the U.S. have been through.”

More than half of the researchers involved today are Turkish experts and students, and local participation remains central to the project’s success.

“A topic that regularly accompanies what we are doing is how are we doing it? How do we include local expertise?” Alexandridis said.

Today, women from the Sardis region work alongside men in excavation and restoration efforts.

A Local Connection to an Ancient City

Leyla Uğurer, now a doctoral student in history of art and archaeology, grew up near Sardis. She first studied English language and literature at Istanbul University before deciding to pursue classical archaeology.

“To learn archaeology, you have to work at the site as well,” she said.

Beginning in 2022, she surveyed rock cut tombs dating from the Lydian through Roman periods around Sardis. She continued that work for three summers before supervising the excavation of a late Roman site this year.

Her experience at Sardis inspired her to pursue a Ph.D. at Cornell, where Alexandridis became her adviser. Both share an interest in funerary art, which provides insights into beliefs about beauty, the afterlife, and everyday life.

This was the city on “one of the most important trade roads in the ancient world,” where the first coin was minted and Alexander the Great visited, Uğurer said. “You were raised there, so you have the same culture going on in you and around you. I remember looking at archaeologists when I was a child and admiring them. To be familiar with those archaeological works going on also helps you understand the archaeological importance more.”

She believes UNESCO recognition will bring important benefits to the region.

“As a local, I can say it is very important,” she said. “First of all, now it is known worldwide and because of UNESCO, there can maybe be more funding for the excavation, also people, more tourists and more research. People will know the area much better, and there will be more protection.”

Protecting Sardis for the Future

Greater protection is badly needed. Sardis’ landscape is vulnerable to natural erosion, while many tumuli have already been damaged by farming. Looting has also become a serious problem.

Alexandridis said treasure hunters now operate on an “industrial dimensions” scale, using explosives, bulldozers, and often weapons to target ancient burial mounds.

Even after nearly seven decades of continuous excavation, researchers say Sardis still has much more to reveal.

“This is why the long-term commitment is so important,” Anderson said. “One season’s work, you’ll learn how to do the thing, but you’re not necessarily going to find something that will be especially significant for the history of the site, until maybe 10 years later, you find something else a little bit further away, and the pieces start to add up.”

The asteroid formed about 155 million years ago when fragments from a violent collision gradually came together. Since then, a subtle but persistent force generated by sunlight has altered its rotation, while traces of ancient water remain preserved in its rocky surface.

On April 20, 2025, Lucy passed within 650 miles of Donaldjohanson while traveling through the main asteroid belt on its way to a group of Jupiter Trojan asteroids. During the flyby, the spacecraft captured the first close-up images and collected detailed scientific measurements. Those observations revealed an asteroid that does not rotate in the simple way scientists expected.

Lucy also provided detailed views of Donaldjohanson’s unusual shape, along with craters, ridges, and other surface features that help tell the story of its evolution.

Lucy’s Asteroid Flyby Reveals an Unusual Rotation

The encounter served as a practice run for Lucy’s future visits to the Trojan asteroids, beginning with its flyby of Eurybates on Aug. 12, 2027. While testing spacecraft systems and mission operations, scientists gained a valuable opportunity to study a previously unexplored asteroid and compare it with Bennu and Ryugu, two asteroids that have been examined up close through sample-return missions.

Researchers reported their findings on June 18 in the journal Science.

Before Lucy’s arrival, astronomers studying Donaldjohanson from Earth noticed a repeating pattern in the asteroid’s brightness. Those observations suggested it was an elongated object completing one rotation every 10.5 Earth days.

The spacecraft’s close-up measurements revealed a more complicated reality.

Instead of rotating around a single axis like most asteroids and planets, Donaldjohanson behaves more like a wobbling spinning top. Scientists found that it turns end-over-end once every 10.5 days while also rocking back and forth around its long axis once every 26.5 days.

Peanut-Shaped Asteroid Formed From Ancient Collision

Earth-based observations had already hinted that Donaldjohanson was elongated, but Lucy showed that the asteroid is actually composed of two connected lobes joined by a narrow neck.

Scientists describe this type of structure as bilobate. It likely formed when two fragments produced by an earlier collision drifted together and merged under their own gravity.

Researchers estimate that the asteroid was spinning at least ten times faster shortly after it formed. Over the last 20 to 60 million years, however, that rotation gradually slowed.

As the spin rate decreased, the balance between centrifugal forces and gravity changed. Loose rock and debris shifted down slopes, reshaping parts of the surface and contributing to the softened appearance of many craters visible in Lucy’s images.

The team believes this slowdown was caused by the YORP effect, a subtle process driven by sunlight.

When sunlight warms an asteroid, the surface releases that energy as infrared radiation. Although the resulting recoil force is extremely small, it acts continuously over millions of years. Because Donaldjohanson’s shape is uneven, those tiny forces do not cancel out completely and instead create a twisting effect that gradually alters the asteroid’s rotation.

The same process can either slow or accelerate an asteroid’s spin. Bennu, which rotates once every four hours, and Ryugu, which rotates roughly once every seven hours, were likely spinning much more slowly in the distant past before YORP sped them up.

Evidence of Ancient Water on Donaldjohanson

As Lucy raced past Donaldjohanson at about 30,000 mph, its instruments detected iron-rich clay minerals on the asteroid’s surface.

These minerals could only have formed in the presence of liquid water. However, scientists believe the water exposure was relatively brief.

Over time, prolonged interaction with water tends to replace iron within clay minerals with other elements such as magnesium. Because the clays on Donaldjohanson remain iron-rich, researchers concluded that liquid water was present only for a limited period.

The situation appears different for Bennu and Ryugu. Both asteroids contain magnesium-rich clays, suggesting they experienced much longer periods of water exposure, possibly lasting millions of years while they were still parts of larger parent bodies.

Those differences may indicate that the parent asteroids formed at different times or in different regions of the solar system before eventually moving into the main asteroid belt.

Comparing Donaldjohanson, Bennu, and Ryugu

Scientists believe Donaldjohanson originated from the rocky remains of a larger asteroid rich in carbon and water that was shattered in a collision within the main asteroid belt.

Bennu and Ryugu likely formed through a similar process and in the same general region. Yet important differences set them apart.

Donaldjohanson is only about 155 million years old, making it much younger than Bennu and Ryugu, which are estimated to have formed 1 to 2 billion years ago.

Its orbital history is also different. Donaldjohanson has remained in the asteroid belt since its formation, while Bennu and Ryugu eventually migrated into near-Earth orbits that periodically bring them close to our planet. Those trajectories made them ideal destinations for sample-return missions.

“It’s helpful for scientists to compare Donaldjohanson with asteroids like Bennu and Ryugu, which are seemingly similar asteroids, because every subtle difference is another clue to our origin story,” said Simone Marchi, Lucy deputy principal investigator and lead author of the study at the Boulder, Colorado, office of the Southwest Research Institute.

“Once we start learning more about the Trojans, a completely different population of space rocks with very different histories, our understanding of solar system formation is destined to be challenged,” said Marchi.

Named after the famous fossilized human ancestor discovered in Ethiopia in 1974, Lucy is on its way to become the first mission to explore Jupiter’s Trojan asteroids. These ancient and relatively unchanged objects formed early in solar system history and may help scientists better understand how the planets formed and migrated before settling into their present-day positions.
