A new study by biologists at Mercyhurst University focuses on the influence of climate change, particularly warmer winters, on the survival and potential fecundity of cold-blooded animals. Cold blooded animals, or ectotherms, do not have an internal mechanism for regulating body temperature. Instead, they rely on solar energy captured by the environment. The purpose of the Mercyhurst study, a collaboration of Michael Elnitsky, Ph.D., assistant professor of biology; and students Drew...

Life Saving Gel From Mussels
2012-12-12 20:15:56

Lee Rannals for redOrbit.com — Your Universe Online Researchers have created a gel that can be painted onto the walls of blood vessels, which could eventually help save lives. The gel can help to prevent the inflammation that typically occurs when a stent is inserted to widen a narrowed artery or vein. This inflammation often counteracts the opening of the vessel that the stent was intended to achieve. The team wrote about the gel in the current issue of the online journal...

Hair Plays Important Role In Keeping Elephants Cool

Alan McStravick for redOrbit.com - Your Universe Online Our ancestors and other species were pretty hairy. They had to be. Body hair on mammals has long been thought of as an evolutionary requirement for survival in cold climes that prehistoric man and the woolly mammoth inhabited. Even today, with the hair on top of your head, you are insulating your body trying to maintain that magic number: 98.6. Or are you? A new study suggests it may do the opposite. Well, where pachyderms are...

Surprising Tips To Beat The Heat
2012-08-21 14:26:02

Lee Rannals for redOrbit.com - Your Universe Online As the heat of summer starts to slow down, and the season of orange and red leaves starts to peek its way around the corner, new science shows just how we can be better about beating the heat next year. Immediately, the thought of ice cream probably sticks in most Americans minds as a way to try and keep cool in the summer's sweltering heat, but in actuality that is flawed thinking, scientists said in a press conference. Shirley O....

Dinosaurs May Not Have Been Cold-Blooded After All
2012-06-28 10:13:58

redOrbit Staff & Wire Reports - Your Universe Online A new study, published Wednesday in the journal Nature, suggests that dinosaurs were warm-blooded creatures, not cold-blooded reptiles as previously thought. According to BBC News Science and Technology Reporter Jason Palmer, researchers have disproven one of the primary bits of evidence supporting the four-decade-old theory that dinosaurs were cold blooded. That evidence, skeletal markings on the creatures' bones known as...

A small, external bioreactor holding human cells pumped out an anti-inflammatory protein to prevent organ damage and other complications in a rat with acute inflammation caused by bacterial products in a model of sepsis, according to a report from researchers at the University of Pittsburgh School of Medicine and the McGowan Institute for Regenerative Medicine. The findings were published today in the inaugural issue of Disruptive Science and Technology. Inflammation is a necessary...

The body's natural inflammatory response is an essential reaction to injury and infection. When acute inflammation escalates out of control, such as in sepsis, it causes nearly 10% of deaths in the U.S. and more than $17 billion in healthcare costs each year. A group of researchers have developed a groundbreaking biohybrid device that can control acute inflammation to prevent sepsis and other related life-threatening complications, as described in an article in the inaugural issue of...
