A new study explains how a parakeet's brain helps it to mimic human words.

A leaping robot could have application in search and rescue, construction, even forest monitoring. But how do you design a robot to stick a landing on a branch or pipe? Biologists worked with robot designers to discover how squirrels do it, and used what they…

New RNA-based active agents reliably protect plants against the Cucumber mosaic virus (CMV), the most common virus in agriculture and horticulture. They were developed by researchers at the Martin Luther University Halle-Wittenberg (MLU). The active…

The EPA's network consistently failed to capture air quality in communities of color across six major pollutants. The monitors are the key data source driving decisions about pollution reduction, urban planning and public health initiatives. The data may…

Marijuana is now legal in many places, but is it safe? Two new studies add to mounting evidence that people who use cannabis are more likely to suffer a heart attack than people who do not use the drug, even among younger and otherwise healthy adults. The…

An AI system can tell the calorie count, fat content, and nutritional value of a meal just from a photo.

A research team has developed a groundbreaking deep learning-based method for analyzing the cytoskeleton -- the structural framework inside cells -- more accurately and efficiently than ever before. This advancement could transform how scientists study cell…

In advancing sustainable energy solutions, an international collaborative team of scientists has achieved a significant milestone in low-carbon chemical conversion. In their recent publication in Nature, the team, led by Professors Zhengxiao GUO of Department…

Researchers conducted a large-scale online survey of clinicians in the Asia-Pacific region to investigate treatment policies for the gastric cancer-causing bacteria Helicobacter pylori.

Although fungi of the genus Piloderma are common, scientists have now discovered five previously unknown species. One of these is one of the most widely distributed species in Northern Europe, while another is found only in old-growth forests. The discoveries…

A study reveals how the Wingless signalling pathway shapes the embryonic intestine of the Drosophila fly, activating a mechanism involved in calcium transport. The finding redefines the role of calcium in organ formation in developing organisms.

The discovery sheds light on how certain bacteria -- including strains that cause food poisoning and anthrax -- form spores for survival.

A team of scientists have brought together methods to see beyond the limitations of conventional weather records, which typically only cover the past century.

New active ingredients such as antibodies are usually tested individually in laboratory animals. Researchers have now developed a technology that can be used to test around 25 antibodies simultaneously in a single mouse. This should not only speed up the…

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.

A significant amount of the milk used in a popular cooking cheese can be substituted with plants, all while maintaining its taste and texture. Researchers have demonstrated this by creating a hybrid version of paneer, a popular South Asian cheese, with…

Climate change is not just an environmental issue -- it's a mental health crisis impacting on adolescent wellbeing right now in areas most affected by climate change, according to new research.

Researchers have mapped the long-range synaptic connections involved in vocal learning in zebra finches, uncovering new details about how the brain organises learned vocalisations such as birdsong.

The red coral colonies that were transplanted a decade ago on the seabed of the Medes Islands have survived successfully. They are very similar to the original communities and have contributed to the recovery of the functioning of the coral reef, a habitat…

Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called 'selfish' genes, they can sometimes be harmful or even lethal. A…

Biomass can be converted into valuable gases. But in order to control this process, the amount of water vapor has to be measured. This is notoriously hard, because other components of the gas can affect the measurement. Using quantum cascade lasers, this…

Thorny skates come in two distinct sizes along the Atlantic Coast of North America, but no one could figure out why. Then their numbers began to plummet, and it became imperative for scientists to understand whether their sizes had anything to do with it. Now…

Humans' unique language capacity was present at least 135,000 years ago, according to a survey of genomic evidence. As such, language might have entered social use 100,000 years ago.

Researchers used community input to design Advanced Clean Truck (ACT) air-quality model experiments. Community asked for ACT policy simulations that convert 48% of medium- and heavy-duty vehicles into zero tailpipe emission versions. Researchers simulated how…

Brain implants hold immense promise for restoring function in patients with paralysis, epilepsy and other neurological disorders. But a team of researchers has discovered that bacteria can invade the brain after a medical device is implanted, contributing to…

A major review of over 67,000 animal species has found that while the natural world continues to face a biodiversity crisis, targeted conservation efforts are helping bring many species back from the brink of extinction.

Introducing a new salt levy is another proposal put forward in a comprehensive set of recommended regulations for the food sector.

A new study has found that fortified enclosures also benefit nearby livestock keepers by preventing carnivore attacks.

Researchers have identified the economic and political borders separating El Argar, considered to be the first state-society in the Iberian Peninsula, from its La Mancha and Valencia Bronze Age neighbors some 4,000 years ago. These communities, with less…

Overuse of chemical pesticides has driven resistance in agricultural pests, including the adaptable two-spotted spider mite. Researchers have discovered novel elicitor proteins, Tet3 and Tet4, in mite saliva that could enhance sustainable pest control. They…
