Fewer calories may slow Alzheimer's
...onsethereditary Alzheimer's. The mice were then split
into two groups as young adults: one thatcould eat all it desired ("ad libitum") and the other that had its foodintake reduced by 40 percent over a four-week period (diet-restricted). The researchers were looking specifically at the formation o...
UCSD researchers derive lessons about human evolution from chicken genome
...hicken provides a reference point and allows us to split
the evolutionary tree and look for what features a... roughly 87 million years since humans and rodents split
off from their evolutionary 'family tree.' Added NHRGI director Francis Collins: "Sequencing the c...
New study by UGA researcher shows that Salmonella uses hydrogen as an energy source
...ve three distinct membrane-associated enzymes that split
molecular hydrogen using a unique metal center, which is composed of nickel, iron, cyanide and carbon monoxide," said Maier. "Humans don't make this kind of metal cluster in cells, and so it's an excellent target for therapeutic intervention. Also, m...
New bulls may revive the Texas state Bison Herd
...oss the United States in the 1800s, the bison were split
into what was known as the Northern and the Southern herds, with the latter made up of animals from Texas, eastern New Mexico, eastern Colorado, Kansas, Oklahoma and southern Nebraska. No other animals but those from Texas have been brought in. "Wha...
Endurance running may be key to evolution of human body form
...t arose millions of years ago, at the evolutionary split
of chimpanzees and Homo erectus, conspired to make humans unusually strong endurance runners, permitting our ancient ancestors to compete for food with speedy four-legged carnivores and greatly shaping the distinctive human body form that we know tod...
HIV, diagnostic health care tools top of list for UH researchers
...resent research on the design of proteins that can split
DNA made by pathogenic organisms, which will produce nanomachines that could be used to combat latent infections caused by viruses like HIV. He also will join a focus group exploring energy production from biological nanosystems that could eventuall...
An old adage about apples finds scientific backing
...dy. As part of their study, the French scientists split
the polyphenols found in apples into two general categories: polyphenol monomers which include flavonoids (catechins and epicatechins); and polyphenol oligomers/polymers such as the procyanidins (polymers of catechins and epicatechins), also found in...

the monkeys into six groups of five, anesthetized them and intravaginally treated them with one of five concentrations of PSC-RANTES or saline placebo. Fifteen minutes later, the researchers exposed each monkey to SHIV strain SF162. The highest dose ...

Head lice reveal contact between modern and ancient humans

between modern humans ( Homo sapiens ) and one of our archaic forerunners, Homo erectus , took place about 1.8 million years ago but is statistically consistent with the more recent divergence time of the lice (at 1.18 mya). Reed and colleagues ther...
New therapy for specific form of leukemia
...Through a flaw at the ABL1 gene, a piece of DNA is split
off and 'takes on a life of its own' as it were. This fragment contains the ABL1 gene, connected to another gene. Due to this fusion, ABL1 works non-stop − stimulating cell growth unremittingly. This process leads to an uncontrolled growth of i...
