As ochre sea star ‘baby boomers’ grow up, species showing signs of recovery
2025-10-28
CORVALLIS, Ore. – The “baby boom” of ochre sea stars that followed a population crash a decade ago is enabling the species to recover on the Oregon Coast, according to new research by scientists at Oregon State University and Cal Poly San Luis Obispo.
The study, published in Ecosphere, does not determine whether the boom was triggered by the wasting disease epidemic that pushed ochre sea stars to the brink of extinction in Oregon, or simply a fortunate coincidence.
But either way, a study of multiple sites along the coast revealed many encouraging signs for ochre sea star populations.
“Wasting ...
Six-million-year-old ice discovered in Antarctica offers unprecedented window into a warmer Earth
2025-10-28
A team of U.S. scientists has discovered the oldest directly dated ice and air on the planet in the Allan Hills region of East Antarctica.
The 6-million-year-old ice and the tiny air bubbles trapped inside it provide an unprecedented window into Earth’s past climate, according to a new study published today in the Proceedings of the National Academy of Sciences.
The oldest ice sample from Allan Hills dated by researchers clocks in at 6 million years, from a period in Earth’s history where abundant geological evidence indicates much warmer temperatures and higher sea levels compared to today.
The research was led by Sarah Shackleton ...
When it comes to mating, female mosquitoes call the shots
2025-10-28
A female mosquito only gets one shot to get reproduction right: She mates just a single time in her entire life. With the stakes so high, it would make sense for these insects to be quite choosey when it comes to selecting a mate. And yet a long-standing assumption in the field was that males controlled the process, and females were simply passive recipients of sperm.
“There’s an inherent contradiction in this assumption,” says Rockefeller University and Howard Hughes Medical Institute mosquito expert Leslie Vosshall. “If females have no say, then multiple males ...

Houseplant inspires textured surfaces to mitigate copper IUD corrosion
2025-10-28
WASHINGTON, Oct. 28, 2025 – Copper intrauterine devices are a common contraceptive due to their long-acting effects and affordability. However, the first few months of use are associated with several side effects.
When a copper IUD is first implanted in the uterus, it undergoes a chemical reaction with uterine fluid. This reaction corrodes its surface, causing a burst of copper ions, which can lead to symptoms such as menstrual irregularity, increased menstrual cramps, and pelvic inflammatory disease.
In Biointerphases, an AVS journal published ...
LIGO, Virgo and KAGRA observed “second generation” black holes
2025-10-28
In a new paper published today in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of last year with unusual black hole spins. An observation that adds an important new piece to our understanding of the most elusive phenomena in the universe.
Gravitational waves are “ripples” in space-time that result from cataclysmic events in deep space, with the strongest waves produced by the collision of black holes.
Using sophisticated algorithmic techniques and mathematical models, researchers are able to reconstruct ...
Dicer: Life's ancient repair tool
2025-10-28
Could yeast and humans be any more different? Going by looks alone, probably not. But peering into our genomes reveals surprising similarities. That’s because we share a common ancestor called LECA (last eukaryotic common ancestor). Before this single-celled organism died off around 2 billion years ago, it passed down Dicer, a key protein humans and certain yeasts still rely on today.
“Dicer is ancient,” explains Cold Spring Harbor Laboratory Professor Rob Martienssen. “The mechanisms behind how it directly interacts with RNA are well understood. How it does this in the context of the whole genome, and how that affects genome stability, is still ...
Environmental shifts are pushing endangered reptiles to the brink of extinction
2025-10-28
Climate change is driving many of Australia’s native reptiles toward extinction, and the answers to their future survival may lie in the fossil record.
New research published today in Current Biology originates from an international collaboration with Museums Victoria Research Institute and the Museum für Naturkunde Berlin. The study reveals that the endangered Australian Mountain Dragon (Rankinia diemensis) has been driven into increasingly smaller and more isolated populations over thousands of years as a result of changing climate conditions.
The study combines fossil evidence from natural history museums with genetic data ...

AI produces shallower knowledge than web search
2025-10-28
Learning about a topic by interacting with AI chatbots like ChatGPT rather than following links provided by web search can produce shallower knowledge. Advice given on the basis of this shallow knowledge tends to be sparser, less original, and less likely to be adopted by others. Shiri Melumad and Jin Ho Yun conducted seven experiments with thousands of online participants who were randomly assigned to learn about various topics, including how to plant a vegetable garden, how to lead a healthier lifestyle, or how to cope with financial scams, using either large language models (LLMs) or traditional Google web search links. Participants ...

Opt-out organ donation policies might reduce organ supply
2025-10-28
Every day, 17 Americans die while waiting for an organ transplant. Opt-out organ donation policies, which enroll everyone into post-mortem donation programs by default unless people choose to opt out, have been touted as a way to increase the supply of desperately needed organs. But opt-out organ donation policies may reduce living organ donations, leaving systems no better supplied with lifesaving organs.
Pascal Güntürkün and colleagues analyzed epidemiological data from 24 countries between 2000–2023 and conducted four experimental ...
Message from the oldest-living dogs to dogs and men: Gonad function fights frailty
2025-10-28
West Lafayette, Ind. – Frailty threatens older individuals because it increases their vulnerability to detrimental health outcomes, such as falling, longer hospitalization, or even shortened life expectancy. New research exploring the linkage between frailty and mortality risk points to retaining gonad function as a potent strategy to fight late-life frailty.
The study conducted by scientists at the Gerald P. Murphy Cancer Foundation’s Center for Exceptional Longevity Studies was published last week in the peer-reviewed scientific journal Scientific Reports.
The ...
Distinct brain features in football players may tell who is at risk of long-term traumatic disease
2025-10-28
Brain scans from American football players reveal subtle differences in the brain’s outer grooves when compared to scans from otherwise healthy men who never played contact or collision sports, a new study shows. Its authors say the findings could potentially predict which people are more at risk of chronic traumatic encephalopathy (CTE).
Like many neurodegenerative diseases, CTE is known to worsen over time, and it afflicts many who play contact and collision sports that involve repeated hits to the head. Popular contact sports include soccer and basketball, while common collision sports are ...
Identifying safer implant designs for total hip replacement
2025-10-28
As populations continue to age, total hip replacement (THR) is becoming an increasingly common surgical procedure. Experts estimate that approximately one million THRs are performed each year worldwide. The surgery is often life-changing, as it can fully restore the function of the hip joint, reduce pain, and allow patients to walk and bear weight again. However, as with any major surgery, the procedure is not without risks, especially for older individuals with other health conditions.
A significant complication following THR is a femoral fracture—a break in the thigh bone near the artificial hip joint. This ...
Study reveals clinical frailty scale as a quick predictor of patient risk after heart failure administration
2025-10-28
Frailty is closely linked to adverse outcomes in older adults, particularly those with heart failure. Numerous epidemiologic studies show that frailty has important prognostic value in this population, underscoring the need for routine assessment. At the same time, the concept of frailty has expanded beyond the physical domain to include cognitive and other dimensions, making comprehensive evaluation increasingly complex and less feasible in everyday practice. The Clinical Frailty Scale (CFS) offers a practical alternative: a 9-point, bedside, visually assessed tool that can be completed in minutes. However, key questions remain—how closely ...
