Study shows big game hunters, not climate change, killed off sloths

...ages them, Steadman said. "God save the sloth that comes down to the ground because usually somebody is there to kill it," he said. For the study, Steadman sent samples from the large collection of ground sloth skeletons at the Florida Museum of Natural History on the UF campus, to Paul Martin, a professo...

Scientists and engineers apply nature's design to human problems

...eas of others is usually frowned upon, but when it comes to the work of Mother Nature, scientists are finding they can use nature as a template. An interdisciplinary group of scientists and engineers at the Georgia Institute of Technology recently formed the Center for Biologically Inspired Design (CBID) ...

A 'dimmer switch' for genes

... necklace using similar beads and then a committee comes along and decorates it, putting a gold star here and a diamond there. These modifications give the protein different properties." The "decorations" that were studied were phosphate molecules, which previously had been shown to build up on proteins u...

A New Era Of Hope For Neglected Diseases

...ms better than either sector working alone when it comes to delivering safe, effective, affordable drugs for neglected diseases. In a linked editorial, entitled "A New Era of Hope for the World's Most Neglected Diseases", the PLoS Medicine editors argue that Moran's findings are one of several indicators ...

Prescription pain patch abuse blamed for increase in deaths

...ported. "Oftentimes we don't know where the patch comes from. Sometimes it is from someone who had a prescription or it was purchased on the street or acquired from a friend, so it has been diverted to them," Goldberger said. Goldberger's team, which includes Mark Gold, M.D., a distinguished professor wi...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...when inherited through the female. This discovery comes at a time when a number of developing nations, including South Africa, are considering re-introducing (or continuing the use of) DDT in an attempt to reduce the major health problems caused by malaria. Use of DDT (Dichloro-diphenyl-trichloroethane) ...

Firefly protein lets researchers monitor molecule linked to cancer

...iferase protein to IKB (IKappaB), the protein that comes immediately after IKK in the NF-KappaB pathway. When the pathway is enabled, IKK triggers reactions that lead to the degradation of IKB. In cells with genetically altered IKB, the attached luciferase is broken down too, meaning scientists can detect ...

Fluoride poisoning in China due to clay, not coal

...e released when the coal and clay mixture is burnt comes from the coal. The fluoride that contaminates the food and air comes mostly from the clay, which is taken from fluoride-rich soil, Zheng told SciDev.Net. Simply buildin...

Scientists use gene transfer technology and common virus to block neuropathic pain

... feel pain." That's where the herpes-based vector comes in. Although scientists can use many kinds of vectors to transfer genes into living cells, HSV has a natural ability to travel long distances along nerve fibers to reach the neural cell's nucleus, which makes it the perfect gene delivery vehicle for ...

Field tested: Grasslands won't help buffer climate change as carbon dioxide levels rise

The UCLA biochemists determined the structures from their analysis of small crystals, using X-ray crystallography. How microcompart...

Environment, not genes, key in family relationships

...nature may play a larger role than nurture when it comes to family relationships between adolescents and their parents. Researchers from the University of Texas at Austin and George Washington University in Washington, D.C., used data on 674 families, each with a same-sex adolescent pair, to evaluate the ...

Enzyme affects hypertension by controlling salt levels in body

...western and co-senior author of the study. "Sodium comes into the kidney cell through these channels and is then returned to blood circulation through another sodium transporter," he said. "The sodium channel critically governs how much sodium gets reabsorbed." Normally, the kidney filters and reabsorbs a...

New technique could alter field of mouse genetics

...r at Carnegie Institution in Baltimore. "It really comes down to its application in practice -- how well it works, day in and day out. It's fairly rare to get a transposon that works on a large scale in an effective way. This looks very promising." Transposons have been used in mice before. But one such a...

Computers close in on protein structure prediction

...state, like a ball that rolls down a hill until it comes to rest on level ground. The energies of hundreds of thousands of possible shapes generated by the computer are computed, and the lowest energy shape is selected as the prediction. The prediction process happens in two steps, Bradley said. The first...

Colorful bacteria more dangerous

Similar molecules also give carrots their color and are often touted for their ability to boost the immune system. Nizet and colleagues now show that these pigmented molecules help S. aureus defuse dam...

UIC researchers show protein routes messages in nerve cells

... basis of this condition remains unknown. "It all comes down to the receptors being in the right place at the right time," said Featherstone. "So our question was, how do these receptors know where they're supposed to go at the time they're supposed to be there?" Fruit flies proved to be ideal test anima...
