New analysis explains collagen's force
Research combining experimental work and detailed molecular simulations has revealed, for the first time, the complex role that water plays in collagen—a protein that is a component of tendons, bone, skin ...
Who's going to win? The answer could change by the hour
The outcome of that big sporting event you just can't wait to watch may depend on how the timing of the match aligns (or doesn't) with the internal biological clocks of the athletes on the teams, according ...
How would the world change if we found extraterrestrial life?
In 1938, Orson Welles narrated a radio broadcast of "War of the Worlds" as a series of simulated radio bulletins of what was happening in real time as Martians arrived on our home planet. The broadcast is ...
Did genetic links to modern maladies provide ancient benefits?
Psoriasis, a chronic skin condition, can cause rashes that itch and sting.
Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Genetic safety switches could help curb potential bioterror risks
The potential threat of bioterrorism using man-made biological organisms could be reduced, thanks to a new method developed by scientists.
New strategy to combat 'undruggable' cancer molecule
Three of the four most fatal cancers are caused by a protein known as Ras; either because it mutates or simply because it ends up in the wrong place at the wrong time. Ras has proven an elusive target for ...
Chemists find a way to unboil eggs
UC Irvine and Australian chemists have figured out how to unboil egg whites – an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion ...
Early human ancestors used their hands like modern humans
New research suggests pre-Homo human ancestral species, such as Australopithecus africanus, used human-like hand postures much earlier than was previously thought.
The importance of the position of cell nuclei for a correctly formed retina
We perceive our environment mostly with our eyes: the visual system delivers about 80 percent of the information processed in the brain. The retina contains all the neurons responsible for transmitting visual ...
Predators, parasites, pests and the paradox of biological control
When a bird swoops down and grabs a caterpillar devouring your backyard garden, you might view it as a clear victory for natural pest control.
'Molecular scissors' could prevent genetic diseases before conception
Scientists from our Department of Biology & Biochemistry have developed a new technique that will streamline biomedical research and could in the future prevent genetic diseases before the moment of conception.
Research shows relationship critical for how cells ingest matter
To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually ...
Team isolates stem cell that gives rise to bones, cartilage in mice
Researchers at the Stanford University School of Medicine have discovered the stem cell in mice that gives rise to bone, cartilage and a key part of bone marrow called the stroma.
