Eye cells "rewire" themselves when vision begins to fail
2025-07-07
Scientists at the Jules Stein Eye Institute at the David Geffen School of Medicine at UCLA have discovered that certain retinal cells can rewire themselves when vision begins to deteriorate in retinitis pigmentosa, a genetic eye disease that leads to progressive blindness. In a study using mouse models, researchers found that rod bipolar cells, neurons that normally receive signals from rods that provide night vision, can form new functional connections with cones that provide daytime vision when their usual partners stop working. The study appears in Current Biology.

Cambridge study shows stem cell grafts can restore myelin in MS lesions in mice
2025-07-07
A study led by Cambridge researchers has shed light on how neural stem cell grafts could help restore myelin in the central nervous system. The findings suggest that neural stem cell-based therapies hold promise as a potential treatment for chronic demyelinating disorders, particularly progressive multiple sclerosis.
Multiple sclerosis (MS) is an autoimmune disease where the body's immune system mistakenly attacks the central nervous system, leading to the destruction of myelin, the protective sheath surrounding nerve fibres. This damage is a leading cause of neurological disability in young adults.
In the early stages ...

Voracious honey bees threaten the food supply of native pollinators
2025-07-07
The majority of the earth’s plant species, including our crop plants, rely on the services of animal pollinators in order to reproduce. Honey bees and other pollinating insects annually contribute billions of dollars to the U.S. economy, and are responsible for nearly a third of the food that ends up on our tables. Our modern agricultural industry is so reliant on honey bees that humans have introduced them worldwide, and in many cases, they have escaped human management and risen to prominence in natural ecosystems as non-native, ...

Although higher body mass index (BMI) is a known risk factor for breast cancer in postmenopausal women, it’s unclear whether this risk differs among women with and without cardiovascular disease or type 2 diabetes. To investigate, a team led by Heinz Freisling, PhD, of the International Agency for Research on Cancer (the specialized cancer ...
Where the feral buffalo roam in Hong Kong
2025-07-07
Most people associate Hong Kong with skyscrapers and shopping malls, but a small population of feral water buffalo calls the marshlands of South Lantau Island home. And they’re sparking a mix of curiosity, concern, and connection among locals.
A new study published in People and Nature in July 2025 led by City University of Hong Kong (CityUHK) examines how Hong Kong residents feel about their unusual neighbours. These findings suggest opinions are about as diverse as the city itself.
The article is titled “Public attitudes and values regarding a ...
Dark Dwarfs lurking at the center of our Galaxy might hint at the nature of dark matter
2025-07-07
The Anglo-USA team behind the study named them dark dwarfs. Not because they are dark bodies—on the contrary—but because of their special link with dark matter, one of the most central topics in current cosmology and astrophysics research. “We think that 25% of the universe is composed of a type of matter that doesn’t emit light, making it invisible to our eyes and telescopes. We only detect it through its gravitational effects. That’s why we call it dark matter,” explains Jeremy Sakstein, Professor of Physics at the University of Hawai‘i ...
From position to meaning: how AI learns to read
2025-07-07
The language capabilities of today’s artificial intelligence systems are astonishing. We can now engage in natural conversations with systems like ChatGPT, Gemini, and many others, with a fluency nearly comparable to that of a human being. Yet we still know very little about the internal processes in these networks that lead to such remarkable results.
A new study published in the Journal of Statistical Mechanics: Theory and Experiment (JSTAT) reveals a piece of this mystery. It shows that when small amounts of data are used for training, neural networks initially rely on the position of words in a ...

Fig trees convert atmospheric CO2 to stone
2025-07-05
Some species of fig trees store calcium carbonate in their trunks – essentially turning themselves (partially) into stone, new research has found. The team of Kenyan, U.S., Austrian, and Swiss scientists found that the trees could draw carbon dioxide (CO2) from the atmosphere and store it as calcium carbonate ‘rocks’ in the surrounding soil.
The research is being presented this week at the Goldschmidt conference in Prague.
The trees – native to Kenya – are one of the first fruit trees shown to have this ability, known as the oxalate carbonate pathway.
All trees use photosynthesis to turn CO2 into organic carbon, which forms their trunk, ...

Climate change cuts milk production, even when farmers cool their cows
2025-07-04
A new study finds extreme heat reduces milk production by up to 10 percent and adding cooling technologies only offsets about half of the loss.
While recent studies have shown climate change will cut crop production, there has been less research into its impacts on livestock. Dairy farmers already know their cows are vulnerable to heat. What will more heat mean? In one of the most comprehensive assessments of heat’s impact on dairy cows, a study in the journal Science Advances finds one day of extreme heat can cut milk production by up to 10 percent. The effects ...
Frozen, but not sealed: Arctic Ocean remained open to life during ice ages
2025-07-04
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now a new study published in Science Advances, challenges this idea as the research team found no evidence for the presence of a massive ~1km ice shelf. Instead, the Arctic Ocean appears to have been covered by seasonal sea ice—leaving open water and life-sustaining conditions even during the harshest periods of cold periods during the last 750,000 years. This discovery gives insights ...
Some like it cold: Cryorhodopsins
2025-07-04
Imagine the magnificent glaciers of Greenland, the eternal snow of the Tibetan high mountains, and the permanently ice-cold groundwater in Finland. As cold and beautiful these are, for the structural biologist Kirill Kovalev, they are more importantly home to unusual molecules that could control brain cells’ activity.
Kovalev, EIPOD Postdoctoral Fellow at EMBL Hamburg’s Schneider Group and EMBL-EBI’s Bateman Group, is a physicist passionate about solving biological problems. He is particularly hooked by rhodopsins, a group of colourful proteins that enable aquatic microorganisms to harness ...
Demystifying gut bacteria with AI
2025-07-04
Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body’s chemistry and each other. For the first time, researchers from the University of Tokyo used a special kind of artificial intelligence called a Bayesian neural network to probe a dataset on gut bacteria in order to find relationships that current analytical tools could not reliably identify.
The human body comprises about 30 trillion to 40 trillion cells, but your intestines contain about 100 trillion gut bacteria. Technically, you’re carrying around more cells that aren’t ...

Unlocking the hidden biodiversity of Europe’s villages
2025-07-04
Villages, often separated from larger towns and cities, consist of clusters of households and a few public buildings. Despite their long history, the biodiversity of European villages has been understudied compared to urban areas, forests, grasslands, or agricultural fields. A new study reveals their biodiversity potential and how nearby landscapes influence biodiversity patterns and human well-being.
This research was led by an international team from the HUN-REN Centre for Ecological Research with 20 other institutes contributing from Hungary, Romania, Germany, and Italy. Published in Nature Sustainability, ...
Planned hydrogen refuelling stations may lead to millions of euros in yearly losses
2025-07-04
As hydrogen infrastructure is rolled out in the EU, refuelling stations must be distributed according to the same principle in all countries. But now a study from Chalmers University of Technology in Sweden points to shortcomings in EU regulations. Using an advanced model, the researchers show that the distribution of refuelling stations may both be incorrectly dimensioned and lead to losses of tens of millions of euros a year in some countries.
By 2030, EU countries must have built hydrogen refuelling stations at least every ...
Planned C-sections increase the risk of certain childhood cancers
2025-07-04
Children born by planned C-section have an increased risk of developing acute lymphoblastic leukaemia (ALL) later in life. This is shown by a study conducted by researchers at Karolinska Institutet. The researchers emphasise that the risk remains low.
The study, published in The International Journal of Cancer, covers nearly 2.5 million children born in Sweden during two periods, 1982 to 1989 and 1999 to 2015. Of these, 15.5 per cent were born by C-section, i.e. nearly 376,000 children. In the entire group, 1,495 children later developed leukaemia.
