New Haven, Conn. — As rising global temperatures alter ecosystems worldwide, animal species usually have two choices: adapt to changing local conditions or flee to a cooler clime. Ecologists have long assumed that the world’s bird species were best equipped to respond to the pressures of climate change simply because they have the option of flying to higher altitudes or towards global poles. But a new Yale study finds that few bird species are able to escape the realities of a warming world. The findings were published May 28 in the journal Nature Ecology and Evolution. “They can’t move fast enough or far enough to ...

Parental warmth and affection in early childhood can have life-long physical and mental health benefits for children, and new UCLA Health research points to an important underlying process: children’s sense of social safety. The study, published in JAMA Psychiatry, found that children who experience more maternal warmth at age 3 have more positive perceptions of social safety at age 14, which in turn predicts better physical and mental health outcomes at age 17. Greater maternal warmth, defined as more praise, positive tone of voice and acts of affection, ...

A team of scientists from the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy, has identified a unique window shortly after birth in which circulating blood stem cells can be effectively targeted with gene therapy directly in the body. The study, published in Nature, opens new avenues for treating some genetic blood disorders without the need for stem cell transplantation or chemotherapy.  SR-Tiget is internationally recognized as a leading center for lentiviral vector–based ...

Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers—examples include photons, which mediate electromagnetic interactions, and gluons, which govern nuclear forces. When two fermions are exchanged, the quantum wave function picks up a minus sign, i.e., mathematically speaking, a phase of pi. This is totally different for bosons: Their phase upon exchange is zero. This quantum statistical property has drastic consequences for the behaviour of ...

A new study shows how using drones with advanced cameras, ones that detect both heat and light, can help scientists better measure how field-grown wheat plants cope with climate change. By flying these drones over hundreds of wheat varieties, researchers could estimate key traits like how efficiently the plants breathe through their leaves, how leafy they are, and how much chlorophyll they have. They then matched these traits to specific genes in the wheat, identifying genetic markers linked to better performance under normal and dry conditions. ...

Scientists have discovered a range of ‘biomarkers’ that could help to improve detection and treatment of gastrointestinal diseases (GIDs) such as gastric cancer (GC), colorectal cancer (CRC), and inflammatory bowel disease (IBD). Researchers found that certain gut bacteria and metabolites are linked to each disease - suggesting that these biomarkers could help in early, less invasive diagnosis of GIDs, with some markers indicating risk across multiple diseases. They used advanced machine learning and AI-based ...

Mechanoluminescence (ML) is a type of luminescence that occurs when a material emits light in response to an external mechanical stimulus, such as scratching, pressing, or stretching. Unlike electroluminescence (EL) or photoluminescence (PL), ML does not require an electric energy or light excitation; instead, it directly converts mechanical energy into optical emission. Then, devices fabricated from ML materials are inherently passive. This characteristic represents an intelligent and energy-efficient light-emission mode. However, most current ML research mainly focuses on the study of single-matrix materials, whose stress-induced ...

Numbers have a funny way about them. Young math students are taught various strategies to make problem-solving easier. Comparing fractions? Find a common denominator or convert to decimals. The strategies get more complex when doing the kind of math used to describe the activities of DNA, RNA, or protein sequences. In science, when you make a model, its parameters determine its predictions. But what do you do when different sets of parameters result in the same predictions? Call one half 2/4 or 3/6—either way, the result’s the same. In physics, such parameter sets are called gauge freedoms. They play a key role in how we understand electromagnetism and quantum mechanics. Surprisingly, ...
