Fixing global biodiversity policy: Avoiding repeating old mistakes
- ScienceDaily
- 21/1/26 23:16
Global goals for biodiversity must apply to all member states of the UN Convention on Biological Diversity (CBD) also at national level. This is one of four recommendations for improving the global strategy for biodiversity. The researchers analyze why the goals have been largely missed so far and present concrete policy options.
Compelling evidence of neutrino process opens physics possibilities
- ScienceDaily
- 21/1/26 23:16
The COHERENT particle physics experiment has firmly established the existence of a new kind of neutrino interaction. Because neutrinos are electrically neutral and interact only weakly with matter, the quest to observe this interaction drove advances in detector technology and has added new information to theories aiming to explain mysteries of the cosmos.
When push comes to shove, what counts as a fight?
- ScienceDaily
- 21/1/26 23:16
Biologists often study animal sociality by collecting observations about behavioral interactions. These interactions can be things like severe or minor fights, cooperative food sharing or grooming. But to analyze animal behavior, researchers need to make decisions about how to categorize and code these interactions. That gets tricky.
AI used to predict early symptoms of schizophrenia in relatives of patients
- ScienceDaily
- 21/1/26 23:16
Researchers have taken a step forward in developing an artificial intelligence tool to predict schizophrenia by analyzing brain scans. The tool was used to analyze functional magnetic resonance images of 57 healthy first-degree relatives (siblings or children) of schizophrenia patients. It accurately identified the 14 individuals who scored highest on a self-reported schizotypal personality trait...
Southern Africa's most endangered shark just extended its range by 2,000 kilometers
- ScienceDaily
- 21/1/26 23:16
A team of marine scientists has confirmed that southern Africa's most threatened endemic shark - the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) - has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
Melatonin is effective against polycystic kidney disease
- ScienceDaily
- 21/1/26 23:16
Melatonin, a hormone commonly associated with sleep-wake regulation, has been found to reduce cysts in fruit flies, according to researchers. It's a finding that may affect the way we treat some kidney diseases and reduce the need for kidney transplants.
Satellite data reveals bonds between emissions, pollution and economy
- ScienceDaily
- 21/1/26 23:16
Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to scientists.
Two anti-viral enzymes transform pre-leukemia stem cells into leukemia
- ScienceDaily
- 21/1/26 23:16
Viral infections and space travel similarly trigger inflammation and the enzymes APOBEC3C and ADAR1; researchers are developing ways to inhibit them as a means to potentially lower cancer risk for both astronauts and people on Earth.
Researchers simplify the study of gene-environment interactions
- ScienceDaily
- 21/1/26 23:16
Researchers have developed a new computational method for studying genetic and environmental interactions and how they influence disease risk.
Ocean toxin a heartbreaking threat for sea otters
- ScienceDaily
- 21/1/26 23:16
Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web. Climate change projections indicate that toxic blooms and domoic acid exposure will continue to rise.
The dangers of drugged driving are outpacing drunk driving
- ScienceDaily
- 21/1/26 23:16
A recent study of drugged driving shows that a sizable percentage of individuals reported the use of marijuana and other illicit drugs while operating behind the wheel.
Cell 'bones' mystery solved with supercomputers
Our cells are filled with 'bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, actin filaments constantly grow, shrink, bind with other things, and branch off when cells move.
Ocean toxin a heartbreaking threat for sea otters
Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web, according to a study led by the University of California, Davis.

A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists.
Southern Africa's most endangered shark just extended its range by 2,000 kilometers

Extreme black holes have hair that can be combed
Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually among the simplest solutions to Einstein's field equations of general relativity. In fact, black holes can be fully characterized by only three physical quantities: their mass, spin and charge. Since they have no additional "hairy" attributes to...
Researchers propose necessary corrections in global biodiversity policy
Since the founding of the United Nations Convention on Biological Diversity (CBD) in Rio de Janeiro in 1992, member states have regularly agreed on global strategies to bring the increasingly rapid loss of biodiversity to a halt. In 2002, the heads of state adopted the so-called 2010 biodiversity targets. Eight years later, little progress had been made and 20 new, even more ambitious goals were...
AstraZeneca vaccine may not go to older people, EU medicines chief suggests
European Medicines Agency approval could stipulate age range, says Emer CookeCoronavirus – latest updatesSee all our coronavirus coverageThe Oxford/AstraZeneca vaccine may be authorised only for younger people in Europe, because there is insufficient data on how well it works in the over-65s, the head of the regulatory body has suggested.The European Medicines Agency (EMA) is expected to...
Barbs fly over satellite projects from Musk, Bezos
A spat erupted Tuesday between Jeff Bezos and Elon Musk as the tech titans' space firms exchanged barbs over their rival satellite internet projects being evaluated by regulators.

Scientists identify flank instability at a volcano with history of collapse
Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of these mountains using satellite images could help identify previously overlooked instability at some volcanoes, according to Penn State scientists.
Building a corn cob—cell by cell, gene by gene
Corn hasn't always been the sweet, juicy delight that we know today. And, without adapting to a rapidly changing climate, it is at risk of losing its place as a food staple. Putting together a plant is a genetic puzzle, with hundreds of genes working together as it grows. Cold Spring Harbor Laboratory (CSHL) Professor David Jackson worked with Associate Professor Jesse Gillis to study genes...
