Genetic research confirms that non-Africans are part Neanderthal
Some of the human X chromosome originates from Neanderthals and is found exclusively in people outside Africa.

AIDS is at a scientific watershed, says IAS 2011 International Chair Elly Katabira at the opening of the world's largest open scientific conference on HIV and AIDS
More than 5,000 AIDS researchers, scientists, clinicians, community leaders and policy experts gathered in Rome for the opening of the 6th IAS Conference on HIV Pathogenesis, Treatment and Prevention have welcomed the growing momentum in biomedical research, but have warned that the benefits of these advances need to be evenly shared between the global North and South.

'Love your body' to lose weight
Almost a quarter of men and women in England and over a third of adults in America are obese.

New TB test provides more rapid and accurate diagnosis in children than conventional smear microscopy
A new tuberculosis (TB) test, using two sputum specimens from each child, is substantially more sensitive and faster than conventional smear microscopy, detecting twice as many cases among children aged 15 and younger.

What keeps the Earth cooking?
From core to surface, a constant flow of trillions of watts of heat enables Earth's magnetic field, spreads the sea floors, and keeps continents on the move.

Newly developed fluorescent protein makes internal organs visible
Researchers at Albert Einstein College of Medicine of Yeshiva University have developed the first fluorescent protein that enables scientists to clearly

Newer techniques are making cardiac CT safer for children
Coronary computed tomography angiography (CTA) has excellent image quality and diagnostic confidence for the entire spectrum of pediatric patients, with significant reduction of risk with recent technological advancements, according to a study to be presented at the Sixth Annual Scientific Meeting of the Society of Cardiovascular Computed Tomography in Denver, July 14-17.

Study of soil effects from March 11 Japan earthquake could improve building design
Japan's March 11 Tohoku Earthquake is among the strongest ever recorded, and because it struck one of the world's most heavily instrumented seismic zones, this natural disaster is providing scientists with a treasure trove of data on rare magnitude 9 earthquakes.

Seminal historical text now online in culmination of 20 year project
The University of Sheffield today (July 18, 2011) announces the publication of an interactive version of

Researchers provide means of monitoring cellular interactions
Using nanotechnology to engineer sensors onto the surface of cells, researchers at Brigham and Women's Hospital have developed a platform technology for monitoring single-cell interactions in real-time.

Heated AFM tip allows direct fabrication of ferroelectric nanostructures on plastic
Using a technique known as thermochemical nanolithography (TCNL), researchers have developed a new way to fabricate nanometer-scale ferroelectric structures directly on flexible plastic substrates that would be unable to withstand the processing temperatures normally required to create such nanostructures.

NYU researchers develop compound to block signaling of cancer-causing protein
Researchers at New York University's Department of Chemistry and NYU Langone Medical Center have developed a compound that blocks signaling from a protein implicated in many types of cancer.
