On the Trail of Ancient Killers
by Perikis Livas in Tracing Knowledge
The newly unveiled genome of a medieval strain of the mycobacterium that causes leprosy is a technical triumph borne of next-generation sequencing machines and clever new techniques to extract target DNA from a soup of ancient molecules. Awash in data, several labs are racing neck-and-neck to cull DNA from a Most Wanted list of other legendary killers: tuberculosis, plague, cholera, Leishmania, the potato blight, and AIDS. They gather traces of these culprits from ancient teeth, bones, hair, fec........ Read more »

A video map of motions in the nearby universe
by Perikis Livas in Tracing Knowledge
An international team of researchers, including University of Hawaiʻi at Mānoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning and zooming. The video was announced recently at the conference “Cosmic Flows: Observations and Simulations” in Marseille, France, that honor........ Read more »

UH Astrobiologists Find Martian Clay Contains Chemical Implicated in the Origin of Life
by Perikis Livas in Tracing Knowledge
Researchers from the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form (borate), boron may have played a key role in the formation of RNA, one of the building blocks for life.... Read more »

Down the wrong path : Book details psychiatry’s lack of objective science
by Perikis Livas in Tracing Knowledge
Psychiatry — which uses well-intentioned coercion, unscientific diagnoses and psychoactive drugs that do as much harm as good — is a science that is off course, according to a new book co-written by Tomi Gomory, an associate professor in the Florida State University College of Social Work....

A journey to the active Sun
by Perikis Livas in Tracing Knowledge
After approximately two months of preparations in Kiruna in the north of Sweden, the balloon-borne solar observatory Sunrise has lifted off successfully today at 7.37 a.m. CEST. For one week the team has been waiting for favorable weather conditions. Polar winds will now grasp the huge, helium-filled balloon and the gondola, carrying Sunrise westward around the North Pole at a height of more than 35 kilometers. Equipped with the largest solar telescope ever to have left the Earth’s surface........ Read more »

Spooky action put to order
by Perikis Livas in Tracing Knowledge
A property known as «entanglement» is a fundamental characteristic of quantum mechanics. Physicists and mathematicians at ETH Zurich show now how different forms of this phenomenon can be efficiently and systematically classified into categories. The method should help to fully exploit the potential of novel quantum technologies.... Read more »

How Do Organs Know When They Have Reached the Right Size?
by Perikis Livas in Tracing Knowledge
Development is, literally, the journey of a life time, and it is a trip still as mysterious as it is remarkable. Despite new methods to probe how an animal or plant forms from a single cell, biologists have much to learn about the unimaginably complex process. To identify some of the field’s persistent riddles, Senior Editors Beverly Purnell and Stella Hurtley and the news staff of Science have consulted with developmental biologists on our Board of Reviewing Editors and elsewhere. The mys........ Read more »

Mind over mechanics
by Perikis Livas in Tracing Knowledge
It’s a staple of science fiction: people who can control objects with their minds.
At the University of Minnesota, a new technology is turning that fiction into reality.
In the lab of biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.
The technology, pioneered by He, may someday allow people robbed of speech and mobility by neurodegenerative ........ Read more »
