Life arose on hydrogen energy, researchers suggest
How did the first chemical reactions get started at the origin of life and what was their source of energy? Researchers at the Heinrich Heine University Düsseldorf (HHU) have reconstructed the metabolism of the last universal common ancestor, LUCA. They found that almost all chemical steps used by primordial life to piece together the molecular […]
12 Ways To Sneak In Mental Health Breaks Throughout Your Day
Life is busy. You may have to work nine-hour days, care for tiny humans in your house, complete chores or tackle the endless responsibilities that come with being an adult (or, in many cases, all of the above). As wonderful as it would be to turn off your mind for an hour ― or even […]
‘Once-in-a generation’ tardigrade fossil discovery reveals new species in 16-million-year-old amber
They’ve famously survived the vacuum of space, and even returned to life after being frozen for decades in Antarctic moss. But as hard as it is to kill the bizarre microscopic animal, the tardigrade, it’s harder to find one fossilized. In fact, only two have ever been discovered and formally named — until now. In […]
Linker histones tune the length and shape of chromosomes
Human life hinges on the ability of our cells to cram six feet of DNA into a 10-micron nucleus — equivalent to fitting a mile of string inside one green pea. But stuffing genes into cramped quarters is only half the battle. The DNA must also remain organized, carefully coiled into loops that ensure the […]
Can CV Fat Predict Cognitive Function in Women in Midlife?
The quality of cardiovascular (CV) fat in midlife women may predict their cognitive function later on in life, a researcher found. High radiodensity of perivascular adipose tissue (PVAT) around the descending aorta among women in their middle years (average age around 51) was significantly associated with worse working memory in the future (P=0.01), reported Meiyuzhen […]
Portable MRI provides life-saving information to doctors treating strokes
When patients exhibit stroke symptoms, doctors must quickly make a life or death determination: Are their symptoms caused by a clot that can be treated with blood thinners or by bleeding in the brain, which may require surgery? A new Yale-led study shows that a portable MRI device can help identify such intracranial hemorrhages, potentially […]
Small changes in diet could help you live healthier, more sustainably
Eating a hot dog could cost you 36 minutes of healthy life, while choosing to eat a serving of nuts instead could help you gain 26 minutes of extra healthy life, according to a University of Michigan study. The study, published in the journal Nature Food, evaluated more than 5,800 foods, ranking them by their […]
The Phrase That Completely Transformed How I Think About Exercise
For most of my life, I’ve had a tumultuous relationship with exercise. This was mostly due to the fact that I felt like it was a requirement and I was never any “good” at it. I loathed team sports as a kid, and I’d put more energy into pretending I was sick so I could […]
