Grandmas Made Humans Live Longer

Published: October 24, 2012.
Released by University of Utah  

SALT LAKE CITY, Oct. 24, 2012 – Computer simulations provide new mathematical support for the "grandmother hypothesis" – a famous theory that humans evolved longer adult lifespans than apes because grandmothers helped feed their grandchildren.

New Filter Could Advance Terahertz Data Transmission
Salt Lake City, Feb. 27, 2015 - University of Utah engineers have discovered a new approach for designing filters capable of separating different frequencies in the terahertz spectrum, the next generation of communications bandwidth that could allow cellphone users and Internet surfers to download data a thousand times faster than today. Once the filter is designed, it can be fabricated using an off-the-shelf inkjet printer.

Better Catalysts, Made-to-order
SALT LAKE CITY, Feb. 11, 2015 - Most of our food, medicine, fuel, plastics and synthetic fibers wouldn't exist without catalysts, materials that open favorable pathways for chemical reactions to run forth. And yet chemists don't fully understand how most catalysts work, and developing new catalysts often still depends on laborious trial-and-error.

Shade Coffee Is for the Birds
SALT LAKE CITY, Feb. 5, 2015 - The conservation value of growing coffee under trees instead of on open farms is well known, but hasn't been studied much in Africa. So a University of Utah-led research team studied birds in the Ethiopian home of Arabica coffee and found that "shade coffee" farms are good for birds, but some species do best in forest.

Predatory Sea Snails Produce Weaponized Insulin
SALT LAKE CITY, Jan. 16, 2015 - As predators go, cone snails are slow-moving and lack the typical fighting parts. They've made up for it by producing a vast array of fast-acting toxins that target the nervous systems of prey. A new study reveals that some cone snails add a weaponized form of insulin to the venom cocktail they use to disable fish.

Fructose More Toxic Than Table Sugar in Mice
SALT LAKE CITY, Jan. 5, 2015 - When University of Utah biologists fed mice sugar in doses proportional to what many people eat, the fructose-glucose mixture found in high-fructose corn syrup was more toxic than sucrose or table sugar, reducing both the reproduction and lifespan of female rodents.

'Darwinian' Test Uncovers an Antidepressant's Hidden Toxicity
SALT LAKE CITY, Dec. 15, 2014 -- Because of undetected toxicity problems, about a third of prescription drugs approved in the U.S. are withdrawn from the market or require added warning labels limiting their use. An exceptionally sensitive toxicity test invented at the University of Utah could make it possible to uncover more of these dangerous side effects early in pharmaceutical development so that fewer patients are given unsafe drugs.

Ebola Virus May Replicate in an Exotic Way
SALT LAKE CITY, Dec. 11, 2014 - University of Utah researchers ran biochemical analysis and computer simulations of a livestock virus to discover a likely and exotic mechanism to explain the replication of related viruses such as Ebola, measles and rabies. The mechanism may be a possible target for new treatments within a decade.

A Path to Brighter Images And More Efficient LCD Displays
SALT LAKE CITY, Nov. 20, 2014 - University of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light. Polarizers are indispensable in digital photography and LCD displays, but they block enormous amounts of light, wasting energy and making it more difficult to photograph in low light.
