A new study calls into question the primacy of meat eating in early human evolution.

Scientists have found that four COVID-19 vaccines prompt the body to make effective, long-lasting T cells against SARS-CoV-2. These T cells can recognize SARS-CoV-2 Variants of Concern, including Delta and Omicron.
Genetic analyses helped identify a new cryptic shark species of the genus Squatina from the Western Atlantic Ocean.
A new study could help to breed more resilient crops as well as shed light on mechanisms that play a critical role in plant growth. The study focuses on how phenotypic plasticity, or the way a given trait can differ as a result of environmental conditions, influences the growth of sorghum.
An estimated 20 percent of teens and young adults who seek treatment for addiction may have previously unrecognized social impairment characteristics of an autism spectrum disorder, a new study finds.
At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when stars explode. This makes it one of the only confirmed intermediate-mass black holes, an object that has long been sought by astronomers.
Last summer's Western North American heat dome caused more than record-breaking temperature increases--rising anxiety about climate change is reported in a new study on the weather event's impact on our mental health.
New research turns the old idiom about not being able to walk and chew gum on its head. Scientists have shown that the healthy brain is able to multitask while walking without sacrificing how either activity is accomplished.
Women ages 35 years and younger were 44% more likely to have an ischemic stroke (caused by blockages of blood vessels in the brain) than their male counterparts, according to a new review of more than a dozen international studies on sex differences in stroke occurrence. This gap narrows between the ages of 35 and 45, and there is conflicting evidence about whether women or men have more ischemic...
More than 70 million tons of carbon were prevented from being released into the atmosphere under a deforestation emissions reduction scheme in Indonesia -- but researchers point out this is only 3 per cent of the total required by Indonesia's Nationally Defined Contribution (NDC) under the Paris Agreement.
For the first time, University of Utah Health scientists have shown that artificial intelligence could lead to better ways to predict the onset and course of cardiovascular disease. The researchers, working in conjunction with physicians from Intermountain Primary Children's Hospital, developed unique computational tools to precisely measure the synergistic effects of existing medical conditions...
Protein folding diseases, from Alzheimer's to Gaucher's, may one day be treated by a unique class of protein corrector molecules that are already helping manage cystic fibrosis.
A new study found that spousal education is positively related to people's overall health, with an effect size that rivals the impact of a person's own education.
Scientists set out to discover if there is sufficient green space, such as private gardens, parks and other recreational areas, within our towns and cities to grow enough fresh food to feed local populations.
Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland.
A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs' body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all...
A large data analysis shows a rare respiratory disease called primary ciliary dyskinesia (PCD) is more common than previously thought.
People with underweight who drink excessively may be at an even higher risk of dying from heart disease, cancer and other causes, according to a new study.
Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, time, and money.
A recent study finds a technique that uses dried spots of blood to measure health indicators in elephants is comparable to techniques that use larger blood samples and require immediate cold storage -- technology that is not always available when monitoring animals in the wild.
In a natural setting, cows and nursing calves together set the feeding schedule for the calf, and calves wean gradually, completing weaning at varying ages. By contrast, in artificial rearing systems with minimal cow-calf contact, the weaning schedule may be strictly determined, with reductions of milk intake based solely on the calf's age. But how well do different calves thrive under different...
Chimpanzees don't automatically know what to do when they come across nuts and stones. Researchers have now used field experiments to show that chimpanzees thus do not simply invent nut cracking with tools, but need to learn such complex cultural behaviors from others. Their culture is therefore more similar to human culture than often assumed.
New pose estimation software has the potential to help neurologists and their patients capture important clinical data using simple tools such as smartphones and tablets, according to a new study.
Hippopotamuses are rather vocal animals. Their 'wheeze honk' calls can be heard over long distances, leading researchers to suspect the calls play an important role in maintaining social groups. Now, a new study shows that hippos recognize each other's voices. They also respond less aggressively to the calls of a neighbor compared to those of a stranger.
Researchers have found that induced pluripotent stem cell--derived cardiomyocytes from a patient with arrhythmogenic cardiomyopathy recapitulate the reduced contractility and impaired desmosome assembly associated with this disease, providing a rapid and convenient platform for developing new treatments such as gene replacement therapy.
