Progress on HIV/AIDS significant but insufficient

...ant but insufficient". Citing achievements in the core areas of political leadership, funding, the intensity and reach of prevention programmes, and the availability of drug therapies, he said, however, that last year saw more new infections and more AIDS-related deaths than ever before. With the epidemi...

Evolution of life on Earth may hold key to finding life in outer space

...nation working on the history and evolution of the core ribosomal machinery, Fox and his team of scientists focus on comparing the sequences and 3-D shapes of biological molecules. Their research benefits greatly from the many ongoing genome sequencing projects. "We do a lot of what is called bioinformat...

NYU biologists map out early stages of embryo formation

... 20,000 genes in C. elegans, the embryo requires a core set of less than 1,000 genes to coordinate the early events that guide the development of the animal. The results further suggest specific roles for new genes that had not been studied before, and functional tests of a subset of these supported the p...

New NIAID grants strengthen national biodefense and emerging infectious diseases research network

...eutic and diagnostic concepts * make available core facilities to approved investigators from academia, government, biotech companies and the pharmaceutical industry * provide facilities and scientific support to first responders in the event of a national biodefense emergency The previously esta...

UF scientist finds unexpected link between cat and human AIDS viruses

...amoto's team was also surprised to discover that a core protein found in HIV also effectively protects cat... appear to be regions of HIV, or variations of the core protein we used in our studies, that may provide protection in vaccine form against HIV." Some com...

Pulp mill devastates swans' sanctuary in Chile

...os Anwandter Nature Sanctuary. When we visited the core of the sanctuary in August, we could find only four." The Carlos Anwandter Nature Sanctuary covers more than 12,000 acres of wetlands along the Cruces river in the southernmost Chilean province of Valdivia. An officially designated "wetland of inter...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

Stroke treatment a step closer after trial

...come blocked and the brain is starved of oxygen. A core area of the brain dies within minutes but it is the threatened area around this core that the treatment may help to salvage. "The protein targets the molecule that causes inflammation ...

University of Arizona plant scientists to unravel maize genome

...s research capabilities as one of the university's core strengths with high potential for leveraging of state investments. "The genome sequence will tell us which genes we need to focus on to develop corn varieties that produce higher yield and better quality with less water on less land," said Wing, who...

Cord blood cells may widen treatment window for stroke

...ion that nerve cells inevitably die quickly in the core region of the brain most severely deprived of oxygen and nutrients when a stroke hits. Instead, the researchers suggest, many nerve cells within ground zero of the attack, like those in mild to moderately damaged outlying areas, may succumb over seve...

Why we give: New study finds evidence of generosity among our early human ancestors

...rven (University of California ?Santa Barbara). "A core feature of reciprocity is the contingent relationship between acts of giving and receiving among social partners. Contingency is important because it sets the rules for who qualifies as a free-rider or cheater in exchange relations." A rigorous effo...

Microbes under Greenland Ice may be preview of what scientists find under Mars' surface

UCLA imaging study of children with autism finds broken mirror neuron system

...se we finally have an account that can explain all core symptoms of this disorder." Conducted at the Semel Institute's Ahmanson-Lovelace Brain Mapping Center, the research used functional magnetic resonance imaging (fMRI) to measure brain activity in 10 high-functioning children with autism while they im...

Pacific Islands paradise protected

Genes involved in cell growth and cell division identified

...and the regulation of growth in human cells as the core machinery involved in this process is very similar in all multicellular organisms from insects to humans. Because the regulation of cell growth is central for embryonic development as well as cancer, it is highly important to have a holistic view on ...

Researchers get neurons and silicon talking

...ologies initiative of the IST programme. NACHIP's core achievement was to develop a working interface between the living tissue of individual neurons and the inorganic compounds of silicon chips. It was a difficult task. "We had a lot of problems to overcome," says Vassanelli. "And we attacked the probl...

Ebola DNA vaccine produces immune responses in all fully vaccinated volunteers in Phase 1 trial
