Timothy Ray Brown, 45, from San Francisco Bay Area, is in the news – as the first man cured of HIV- AIDS. “I think so,” he calmly tells his interviewers who ask if he actually is cured. Brown has been facing cameras, gun mikes and diagnostic kits ever since the publication of a research paper on his unique case in the journal Blood in December 2010. The researchers led by Kristina Allers and

Tempe, Ariz. - An international team of scientists, including two from Arizona State University, have taken a significant step closer to unlocking the secrets of photosynthesis, and possibly to cleaner fuels. Plants and algae, as well as cyanobacteria, use photosynthesis to produce oxygen and "fuels," the latter being oxidizable substances like carbohydrates and hydrogen. There are

Ovarian and breast cancer treatments being developed that mix a protein inhibitor and traditional anticancer drugs are showing signs of success, according to a new review for Faculty of 1000 Biology Reports. Susan Bates and Christina Annunziata looked at several recent papers on this form of treatment, which takes advantage of the synthetic lethality of BRCA (breast cancer

A team of paleontologists has discovered a new dinosaur species they're calling Abydosaurus, which belongs to the group of gigantic, long-necked, long-tailed, four-legged, plant-eating dinosaurs such as Brachiosaurus. In a rare twist, they recovered four heads – two still fully intact – from a quarry in Dinosaur National Monument in eastern Utah. Complete skulls have been

The origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers. A study appearing online this week in the Proceedings of the National Academy of Sciences unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of the major moments in plant evolution, when the

Baby monitors of the future could translate infant cries, so that parents will know for certain whether their child is sleepy, hungry, needing a change, or in pain. Japanese scientists report details of a statistical computer program that can analyze a baby's crying in the International Journal of Biometrics. As any new parent knows, babies have a very loud method of revealing

Two species of damselfish may look identical—not to mention drab—to the human eye. But that's because, in comparison to the fish, all of us are essentially colorblind. A new study published online on February 25th in Current Biology, a Cell Press publication, reveals that the fish can easily tell one species from another based entirely on the shape of the ultraviolet (UV) patterns

New research from scientists in Liverpool has revealed the relationship between agility and vision in mammals. The study, published today in the Journal of Anatomy, sampled 51 species to compare the relationship between agility and vision between frontal eyed species, such as cats, to lateral-eyed mammals such as rabbits, to establish if the positioning of the eyes resulted in

MADISON — Genetic interactions between avian H5N1 influenza and human seasonal influenza viruses have the potential to create hybrid strains combining the virulence of bird flu with the pandemic ability of H1N1, according to a new study. In laboratory experiments in mice, a single gene segment from a human seasonal flu virus, H3N2, was able to convert the avian H5N1 virus into a

For someone with a severe, incurable lung disorder such as cystic fibrosis or chronic obstructive pulmonary disease, a lung transplant may be the only chance for survival. Unfortunately, it's often not a very good chance. Matching donor lungs are rare, and many would-be recipients die waiting for the transplants that could save their lives. Such deaths could be prevented if it

Bands of chimpanzees violently kill individuals from neighboring groups in order to expand their own territory, according to a 10-year study of a chimp community in Uganda that provides the first definitive evidence for this long-suspected function of this behavior.

Scientists have developed way of predicting how likely a person is to live beyond the age of 100. The breakthrough, described in the journal Science, is based on 150 genetic "signposts" found in exceptionally long-lived people. The researchers created a mathematical model, which takes information from these signposts to work out a person's chance of reaching 100.It is based on

Scientists have been surprised to learn that, despite thousands of changes that viruses like HIV undergo in rapid fashion to evade the body's immune system, the original version that caused the infection is still present in the body months later.

One of the characteristics of embryonic stem cells is their ability to form unusual tumors called teratomas. These tumors, which contain a mixture of cells from a variety of tissues and organs of the body, are typically benign. But they present a major obstacle to the development of human embryonic stem cell therapies that seek to treat a variety of human ailments such as

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy portion of an individual's life span can be extended, it may delay the onset of certain age-related diseases. In the search to understand these molecular
