The snow leopard (Panthera uncia) is a large feline unique to the Qinghai-Tibet Plateau and its surrounding areas. As the apex predator in the region, the snow leopard plays a crucial role in maintaining ecological stability. Its unique characteristics, coupled with its striking appearance, have made it a flagship species for conservation efforts aimed at protecting the ecosystem of the Qinghai-Tibet Plateau. Unfortunately, few snow leopard fossils have been found in the Qinghai-Tibet Plateau region, particularly fossils from the Quaternary period. As a result, it’s unclear how snow leopards evolved their specialized adaptations to this environment. On the one hand, molecular ...

According to the United Nations, soil salinization affects between 20% and 40% of arable land globally, with human activity and climate change – especially rising sea levels – largely responsible for this process. While the human body needs sodium to function, this is not the case for most plants. In fact, excess salt around plants’ roots gradually blocks their access to water, stunting their growth, poisoning them and hastening their death. Ten million hectares of farmland are destroyed by soil salinization every year, posing a threat to global food security. Scientists at EPFL, ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. Scientists from the Wellcome Sanger Institute and their collaborators analysed family trees of hundreds of single cells from several individuals. The team pieced together these family trees from patterns of shared mutations between the cells, indicating common ancestors. Researchers uncovered unexpected ...

Researchers have discovered a biological mechanism that makes plant roots more welcoming to beneficial soil microbes.  This discovery by John Innes Centre researchers paves the way for more environmentally friendly farming practices, potentially allowing farmers to use less fertiliser.   Production of most major crops relies on nitrate and phosphate fertilisers, but excessive fertiliser use harms the environment.  If we could use mutually beneficial relationships between plant roots and soil microbes to enhance nutrient uptake, ...

CAMBRIDGE, MA -- Nearly 50 years ago, neuroscientists discovered cells within the brain’s hippocampus that store memories of specific locations. These cells also play an important role in storing memories of events, known as episodic memories. While the mechanism of how place cells encode spatial memory has been well-characterized, it has remained a puzzle how they encode episodic memories. A new model developed by MIT researchers explains how those place cells can be recruited to form episodic memories, even when there’s no spatial component. According to this model, place cells, along with grid cells found in the entorhinal cortex, act as a scaffold ...

More than 100,000 of them die, according to the World Health Organization, and 300,000 suffer severe complications and lasting disability ...

Proteins are the foundation of all life we currently know. With their virtually limitless diversity, they can perform a broad variety of biological functions, from delivering oxygen to cells and acting as chemical messengers to defending the body against pathogens. Furthermore, most biochemical reactions are only possible thanks to enzymes, a special type of protein catalysts. The molecular surface of proteins is the key to their function, such as docking small molecules or other proteins or driving ...

An international team of geneticists, led by those from Trinity College Dublin, has joined forces with archaeologists from Bournemouth University to decipher the structure of British Iron Age society, finding evidence of female political and social empowerment.   The researchers seized upon a rare opportunity to sequence DNA from many members of a single community. They retrieved over 50 ancient genomes from a set of burial grounds in Dorset, southern England, in use before and after the Roman Conquest of AD 43. The results revealed that this community was centred around bonds of female-line descent.  Dr Lara Cassidy, Assistant Professor in Trinity’s Department of Genetics, led ...

Researchers at Nagoya University in Japan have discovered sophisticated behavioral strategies that enable parasitic crickets to survive within ant colonies.
