Researchers crack the peanut genome: New genome map sheds light on ancestry, diversity of today's peanuts
Researchers working as part of the International Peanut Genome Initiative have previously pinpointed one of the peanut's two wild ancestors and shown that the peanut is a living legacy of some of the earliest human agricultural societies in South America. Since then the team has mapped the entire peanut genome
Arsenic-breathing life discovered in the tropical Pacific Ocean
"Thinking of arsenic as not just a bad guy, but also as beneficial, has reshaped the way that I view the element," said first author Jaclyn Saunders, who did the research for her doctoral thesis at the UW and is now a postdoctoral fellow at the Woods Hole Oceanographic Institution
5 Remarkable Examples of Animal Intelligence That Will Leave You in Awe
Animal intelligence could stretch to more than just an elephant’s excellent memory! As these examples will reveal..
Scientists print first 3D heart using patient's biological materials: Engineered heart completely matches the immunological, cellular, biochemical and anatomical properties of the patient
Until now, scientists in regenerative medicine -- a field positioned at the crossroads of biology and technology -- have been successful in printing only simple tissues without blood vessels.
Features that make lizards appealing to potential mates are resilient to stress
"Animals in the wild experience stress every day when they flee from predators, fight with others over food, or face extreme weather," said Kirsty MacLeod, a postdoctoral scholar at Penn State at the time of the research and lead author of the paper. "But they are facing increasing amounts of
Puncture performance of viper fangs measured
They report their findings in the Royal Society journal Biology Letters.
A biosynthetic dual-core cell computer
To date, biotechnologists had attempted to build such digital circuits with the help of protein gene switches in cells.
Engineers tap DNA to create 'lifelike' machines
Using what they call DASH (DNA-based Assembly and Synthesis of Hierarchical) materials, engineers constructed a DNA material with capabilities of metabolism, in addition to self-assembly and organization -- three key traits of life. "We are introducing a brand-new, lifelike material concept powered by its very own artificial metabolism. We are
Eelectrostimulation can improve working memory in people: As memories fade, can we supercharge them back to life?
Reinhart and Nguyen's research targets working memory -- the part of the mind where consciousness lives, the part that is active whenever we make decisions, reason, and recall our grocery lists.
Bacterial therapy in a dish
Recent research has found that many bacteria selectively colonize tumors in vivo, prompting scientists to engineer them as programmable vehicles, biological "robots" in other words, to deliver anticancer therapeutics. Researchers are also developing new, "smart" medicines by programming bacteria to tackle other diseases, such as gastrointestinal disease and infections. Key
Scientists build a machine to see all possible futures
"When we think about the future, we are confronted by a vast array of possibilities", explains Assistant Professor Mile Gu of NTU Singapore, who led development of the quantum algorithm that underpins the prototype
"These possibilities grow exponentially as we go deeper into the future. For instance, even if we
Bacteria harness viruses to distinguish friend from foe
"This is the first evidence that cells can distinguish themselves from related competitors through the use of a virus," says Thomas Wood of Pennsylvania State University, one of the co-senior authors on the study. "The implications are that we should re-evaluate the relationship between a virus and its cellular host
Best in snow: New scientific device creates electricity from snowfall: The first-of-its-kind nanogenerator also acts as a weather station
"The device can work in remote areas because it provides its own power and does not need batteries," said senior author Richard Kaner, who holds UCLA's Dr.
