New insights into origin of birds focuses on key characteristics that preceded flight: Body size, forelimb length

Science Daily - Mon, 24/02/2014 - 2:51am
The key characteristics of birds which allow them to fly -- their wings and their small size -- arose much earlier than previously thought, according to new research that examined closely the Paraves, the first birds, and their closest dinosaurian relatives which lived 160 to 120 million years ago. Researchers investigated the rates of evolution of the two key characteristics that preceded flight: body size and forelimb length. In order to fly, hulking meat-eating dinosaurs had to shrink in size and grow much longer arms to support their feathered wings.

Synthetic version of heparin created for use in kidney patients

Science Daily - Mon, 24/02/2014 - 2:51am
A synthetic form of low-molecular-weight heparin has been created that can be reversed in cases of overdose and would be safer for patients with poor kidney function. Heparin is an anticoagulant, and is most commonly extracted from pig intestines in two forms: unfractionated heparin, which is commonly used in procedures such as dialysis, and a more-refined low-molecular-weight (LMW) heparin, which is used around the world for preventing dangerous blood clots.

Mysterious polio-like illness found in five California children

Science Daily - Mon, 24/02/2014 - 2:51am
Researchers have identified a polio-like syndrome in a cluster of children from California over a one-year period, according to a case report released. Polio is a contagious disease that sometimes caused paralysis. The United States experienced a polio epidemic in the 1950s, until a vaccine was introduced. The five children experienced paralysis of one or more arms or legs that came on suddenly and reached the height of its severity within two days of onset. Three of the children had a respiratory illness before the symptoms began. All of the children had been previously vaccinated against poliovirus. The children were treated but their symptoms did not improve and they still had poor limb function after six months.

Science Daily - Mon, 24/02/2014 - 2:50am
A new study has looked at intensification of initial therapy for all children with Kawasaki Disease in order to prevent IVIG-resistance and associated coronary artery abnormalities by assessing the addition of the medication infliximab to current standard therapy. Kawasaki Disease is a severe childhood disease that many parents, even some doctors, mistake for an inconsequential viral infection. If not diagnosed or treated in time, it can lead to irreversible heart damage.

Japanese Firm Proposes Microwave-Linked Solar Plant On the Moon

Slashdot - Mon, 24/02/2014 - 12:19am
littlesparkvt writes "Harnessing the sun's power is nothing new on Earth, but if a Japanese company has its way, it will build a solar strip across the 11,000 mile Lunar equator that could supply our world with clean and unlimited solar energy for generations." Some of the company's other projects look just as ambitious.

Study Shows Agent Orange Still Taints Aging C-123s

Slashdot - Sun, 23/02/2014 - 11:15pm
__roo writes "Herbicides used in Vietnam in the 1970s still pose a threat to servicemen, according to a study published Friday. The U.S. Air Force and Department of Veteran Affairs denied benefits to sick veterans, taking the position that any dioxin or other components of Agent Orange contaminating its fleet of C-123 cargo planes would have been 'dried residues' and unlikely to pose meaningful exposure risks. According to the lead researcher, 'The VA, whether out of ignorance or malice, has denied the entire existence of this entire branch of science. They have this preposterous idea that somehow there is this other kind of state of matter — a dried residue that is completely inert.' To show that such exposures happened, her research team had to be 'very clever.'"
