Immunologists have identified an important intermediate step in innate immune defense.

A new study shows that horses can be more reluctant in new situations if they have multiple riders, have had several owners or the horse has been with its current owner only for a short period of time. The results of the international research group th…

Thirty-eight Chinese cities have reduced their emissions of planet-warming carbon dioxide (CO2) despite growing economies and populations for at least five years — defined as proactively peaked cities, a new study reveals.

A report into the global status of ladybirds reveals the threats they face and lays out a roadmap for conservation. These vital pest controllers for farmers and gardeners are considered to be in decline globally due to human activities, and species are…

Topological insulators are regarded as the key to novel ‘spintronic’ devices and quantum computers of the future due to their unique electronic properties. Physicists have now been able to understand for the first time how the topological properties of…

New research shows that if it were not for the impact of climate change, up to 50 percent of residences in Houston’s Harris County would likely not have been flooded by Hurricane Harvey five years ago. The study coincides with the fifth anniversary of …

Researchers have found that a novel blood test can be used to easily evaluate disease severity in patients with pulmonary arterial hypertension (PAH) and predict survivability. PAH is a rare, life-threatening condition that causes unexplained high bloo…

Thousands of short RNA sequences that code for microproteins and peptides have been identified, opening new avenues for disease research and drug development.

Researchers have known people who live farther from the equator are more likely to develop multiple sclerosis (MS) and have often attributed that to vitamin D exposure. But countries farther from the equator are also more likely to be wealthier than co…

Lessons learned from the public health responses to the HIV and COVID-19 pandemics should help guide the response to the current outbreak of monkeypox, National Institutes of Health experts write in a new editorial.

Machine learning has helped scientists understand how the brain gives rise to complex human characteristics, uncovering patterns of brain activity that are related to behaviors like working memory, traits like impulsivity, and disorders like depression…

Chemotherapy sucks. The treatments generally have awful side effects, and it’s no secret that the drugs involved are often toxic to the patient as well as their cancer. The idea is that, since cancers grow so quickly, chemotherapy will kill off the dis…

Fossils of a giant killer mosasaur have been discovered, along with the fossilized remains of its prey.

College students who are marginally placed into ‘high-ability’ classes have lower grades and graduation rates, according to new research.

Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating — an idea known as the ‘outside-in’ hypothesis? Or did they evolve independent of sc…

A new, international study suggests that dog owners who spend more time exercising themselves tend to exercise their dogs more, and more active owners are also more likely to perceive their dog’s body weight as being ideal.

Briefly exposing social media users to the tricks behind misinformation boosts awareness of harmful online falsehoods — even amid intense ‘noise’ of the world’s second-most visited website. Google is set to deploy an anti-disinformation campaign based…

A new study asked whether associations between physical activity and sedentary time with death varied based on different levels of genetic predisposition for longevity.

Using a suspended nanowire, a research team has created a tiny sensor that can simultaneously measure electrical and mechanical cellular responses in cardiac tissue, work promising for cardiac disease studies, drug testing and regenerative medicine.

In a survey study of more than 3,000 adults, researchers compared psychedelic experiences with near-death experiences that were not drug related and found notable similarities in people’s attitudes toward death.
