The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. A new article discusses the theoretical properties of “hypercompact stellar systems” and suggests that hundreds of these faint star clusters might [...]
An implanted electronic ion pump in organic material can be used to carry signals to specific cells in the nervous system and in this way treat various illnesses. In a unique study, researchers have used the pumps to successfully manipulate the hearing in laboratory animals. The technique represents a breakthrough for the machine-to-brain interface, with [...]
Through a recent modeling experiment, researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Looking at photos on a cellphone display can be somewhat arduous. A new mini beamer will make it easier. The beamer is so small that it can be integrated in a cellphone or a PDA. As it does not need an extra light source it also conserves the battery.
As the 40th anniversary of the moon landing approaches, a new report finds that overwhelming majorities of Americans believe that science has had a positive effect on society and that science has made life easier for most people. The public also rates scientists highly and believes government investments in science pay off in the long [...]

Researchers have grown dense arrays of single-crystal semiconductors arranged as nanoscale pillars on low-cost, aluminum foil substrates. When the nanopillars are combined with a transparent, positively charged semiconductor that serves as a window, the resulting 3-D photovoltaic promises efficient, cheap, flexible solar cells.

Attractive males release fewer sperm per mating to maximize their chances of producing offspring across a range of females, according to a new article on the evolution of ejaculation strategies. The findings suggest that, paradoxically, matings with attractive males may be less fertile than those with unattractive ones.
New research using high-speed digital imaging shows that, at least for some insects, wings that flex and deform, something like what happens to a heavy beach towel when you snap it to get rid of the sand, are the best for staying aloft.
Scientists took an important first-step toward the development of new treatments to help people with HIV battle Mycobacterium tuberculosis infection. HIV interferes with the cellular and molecular mechanisms used by the lungs to fight TB infection.
