How environment and genomes interact in plant development

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.

Extraordinary black hole found in neighboring galaxy

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.

Women ages 35 and younger are 44% more likely to have an ischemic stroke than male peers

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...

Artificial intelligence identifies individuals at risk for heart disease complications

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...

Overweight dogs respond well to high-protein, high-fiber diet

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...

Calf personality, feeding, and growth: When one style doesn’t fit all

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...

Cracking chimpanzee culture

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.

My heart will go on: Patient-derived heart cells mimic disease in vitro

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.
