A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates. Read more ›

Engineers unlock the power of exceptional points (EPs) for advanced optical sensing. EPs -- specific conditions in systems where extraordinary optical phenomena can occur -- can be deployed on conventional sensors to achieve a striking sensitivity to environmental perturbations. Read more ›

A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking. Read more ›

The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs. Read more ›

A new 'atlas' of the human ovary provides insights that could lead to treatments restoring ovarian hormone production and the ability to have biologically related children, according to engineers. Read more ›

The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and... Read more ›

Some people have genes that protect them from alcohol abuse. An examination of databases at 23andMe reveal that those same alcohol-protective variants have associations with conditions and behaviors that may have nothing to do with alcohol. Read more ›

A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions. Read more ›

Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists have now demonstrated that this. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. The research group hopes to decipher the complex aging process of the brain and gain a better understanding of related degenerative diseases. Read more ›

In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning. It is therefore important to look at functioning as a whole and to take care of the different aspects of physical and mental well-being. Read more ›

In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations. Read more ›

The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which... Read more ›

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species. Read more ›

The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts. Read more ›
