Asymptomatic HIV babies could use earlier treatment

...children,?said Maldonado. “We were able to see the real distribution of illness, what kinds of treatment the children were given and the ages when they started treatment.?/p> The researchers divided the HIV-infected newborns into three groups: those born from 1988 to 1991, from 1992 to 1995 and from 1...

Leprosy genome tells story of human migrations, French researchers report in Science

...lep/stat2002/global02.htm) "Leprosy is still very real and devastating to patients who aren't treated appropriately. The better we can understand this pathogen's genome and the subtle differences among its various strains worldwide, the better position we'll be in to ultimately eliminate the disease," sa...

Immune system's distress signal tells bacteria when to strike back

...ia in this case are "normal flora," people with no real infection develop a chronic disease. The battles between pathogens and their hosts have been going on for millions of years, Alverdy said, with each side constantly devising novel measures, countermeasures, and counter-countermeasures, including sop...

Scientists discover global pattern of big fish diversity in open oceans

...ends towards a reduction in biodiversity. There is real cause for alarm here." Scientists say losing the variety of fish does not bode well for the future health of open oceans. A robust portfolio of different species is a key to maintaining our supply of fish in the long term and the ability of these li...

Caloric restriction won't dramatically extend life span in humans: UCLA research

... your life span is not so dramatic, there are very real costs of being overweight -- including greater risk for heart disease and other life threatening illnesses, Phelan said. The human data factored into the mathematical model include the caloric intake of people in Japan, and their longevity, compared...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...ller prompts brain to release endorphins, bringing real relief to those in pain Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations, a new University of Michigan study finds. The study provides the first dire...

Say what? Bacterial conversation stoppers

...not as dramatic as with the marine bacteria. "The real take-home point is the interference," Bassler said. "Consumption of the signal could be a mechanism that allows one kind of bacteria to block another kind of bacteria from counting how many neighbors they have and, in turn, properly controlling its b...

Missing Receptor Molecule Causes Tumor Growth

It was determined that in 20% of the tissues examined the gene responsible for DR4 was methylated to a higher degree and DR4 was missing. This research support...

"In our experiments we found that when the muscles in one arm were fatigued, the effort required to maintain a set arm position was much greater. When asked to keep both arms in a similar position, where one a...

Study casts doubt on 'Snowball Earth' theory

The evidence from the drill core does not prove that large parts of the ocean re...

'Jumping genes' contribute to the uniqueness of individual brains

Gage, Professor and co-head of the Laboratory of Genetics at the Salk Institute and the lead author of the study published in this week's Nature. This process of creating diversity with the h...

Scientists devise way to measure RNA synthesis on the fly in a live cell

But the scientists in his laboratory have found a way around this with a technique called fluorescence correlation spectroscopy (FCS). First, they use an RN...

Lance Armstrong through a physiological lens: hard training boosts muscle power 8%

...major physiological changes happened, but here's a real quantified example." He added: "Generally there are two ways to improve efficiency: Train your maximum capacity to be very high, or train your sub-maximal capacity to be very efficient. In Armstrong's case, he did both. In the lab they measured his ...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...respond to such social cues as gaze. 'But to get a real understanding of how this response is accomplished at a neuronal level, you need an animal model that you can manipulate physiologically,' said Platt. 'This is the first time it has been shown that such a cognitive ability corresponds so exquisitely ...
