Life detection instrument passes key test on road to Mars

.... This translates into a cheaper and easier way to build instruments, but more importantly, an instrument that is smaller and uses less power. With the success of this crucial field test, Skelley and Mathies are eager to get to work on a prototype of their instrument that would fit in the allowed space wi...

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

...d public suspicions of being unfair, and they must build public trust for the future," she adds. "HIV-positive people in each country affected must be involved in deciding how limited therapies are rationed, and these decisions cannot be made for them by self-appointed experts. We do not want this opportu...

Newest HIV drugs should be used with FUZEON(R)

Data presented at IAS build a compelling case for FUZEON (enfuvirtide, formerly known as T-20) to be combined with the newest drugs to give patients facing resistance their best chance of achieving undetectable viral load ?the optimal treatment goal for all people living with H...

By creating molecular bridge, scientists change function of a protein

Bioinformatics reveals new gene regulation system

...locks of RNA into the deoxyribonucleotides used to build DNA. This conversion is critical for duplicating a bacterium's entire genome before it divides to reproduce. The search revealed a conserved palindromic sequence occurring upstream of many ribonucleotide reductase (Nrd) genes. A genetic palindrome i...

Genetic links could unlock clues to leading cause of blindness

...5 years. The disease causes nodule-like specks to build up in the eye, chipping away central vision over time. But Dawson said most people don't even realize something is wrong until they detect changes in their vision. The disease can be controlled, but there is no known way to reverse the vision loss it...

Modified collagen could yield important medical applications

...provides the sponge-like scaffold upon which cells build nerves, bones and skin. Because it is non-toxic, dissolves naturally over time and rarely triggers rejection, collagen is commonly used in cosmetics, drug delivery systems and biocompatible coatings. Yu's goal is to change some of collagen's bioche...

Until now, most scientists have not attempted to provide engineered tissue with its own blood supply. Instead, they have implanted the new tissue into the body and waited for the body...

Snapin: A protein with therapy potential for autism

...her proteins it binds to." Firestein's goal is to build "a core pathway of dendric branching" ?a sequence of steps, each affecting the next, with cypin at the center. "Our pathway says cypin does this; now what regulates cypin? Here snapin has a role. And what does snapin regulate?" said Firestein. "Our h...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

...l include sediment dredging and transplantation to build six 35-meter-long and 10-meter-wide subtidal banks inside the lagoon. The banks will allow the researchers to test how the chemical content and biodiversity of the lagoon respond to such a local change. The researchers will conduct assessments by ext...

NIH creates nationwide network of molecular libraries screening centers

Penguin chicks exposed to human visitors experience spike in stress hormone

...ne, it takes several minutes for corticosterone to build up in the bloodstream after a stressful event, such as being captured. Additional blood samples were drawn after 30 and 60 minutes. The same procedures were followed when the chicks were 40 to 50 days old and again two weeks before fledging, which oc...

Secrets of the deep may hold key to life on other planets
