Towards more effective treatment for multiple myeloma
A new study from SUNY Downstate Medical Center in Brooklyn, New York, shows that MAL3-101, a recently developed inhibitor of the heat shock protein 70 (Hsp70), appears to have potent anti-tumor effects on multiple myeloma, a bone marrow cancer. Despite aggressive modes of treatments, myeloma ultimately remains incurable. The disease has a high incidence in the communities served by SUNY Downstate. -
22:24With the trend in healthcare moving toward an era of personalized medicine, there is much anticipation and hope that customized approaches to prevention and treatment based on a person's genetic make-up will result in better health outcomes. Some advances, most notably with prevention and treatment of breast and colon cancer, have been widely heralded, raising questions about the potential for personalized medicine for other common diseases, such as diabetes.

21:57By combining detailed chemical measurements in the deep ocean, in the oil slick, and in the air, NOAA scientists and academic colleagues have independently estimated how fast gases and oil were leaking during the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. The new chemistry-based spill rate estimate, an average of 11,130 tons of gas and oil compounds per day, is close to the official average leak rate estimate of about 11,350 tons.

21:57Scientists have independently made the largest direct measurements of the invisible scaffolding of the universe, using the gravitational lensing effect known as "cosmic shear" to build maps of the distribution of dark matter. Their methods show that surveys with ground-based telescopes can measure cosmic shear with enough accuracy to aid in better understanding the mysterious space-stretching effects of dark energy.

21:57New research shows that infectious disease-fighting drugs could be designed to block a pathogen's entry into cells rather than to kill the bug itself. Historically, medications for infectious diseases have been designed to kill the offending pathogen. This new strategy is important, researchers say, because many parasites and bacteria can eventually mutate their way around drugs that target them, resulting in drug resistance.

Obama bans uranium mining around Grand Canyon (Reuters)
Reuters - The Obama administration banned new uranium mining claims around the Grand Canyon for the next 20 years, a move hailed by conservationists on Monday as key to the president's environmental legacy but slammed by opponents as a job-killer.

Jatai bees are the first known bee species to have a specialised soldier class to protect their colony
Scientists have discovered the first known "soldier" bee. The bee, which is larger and heavier than other worker bees in its nest and defends the entrance, has been identified in colonies of a Brazilian stingless bee known as a Jatai.
A team of researchers from Sussex University and the University of São Paulo studied the Jatai bee (Tetragonisca angustula) which lives in colonies of 10,000 individuals in cavity walls, tree trunks or in the ground.
The study, published in the journal Proceedings of the National Academy of Sciences, found that Jatai soldiers are 30% heavier than their forager nestmates, have larger legs and smaller heads. They stand on the tube leading to the entrance of their nest to provide early warning of attack by robber bees, which can kill entire colonies when raiding nests for food.
The new research shows that Jatai soldier bees, unlike guard bees in honeybee colonies, are physically specialised to perform the task of protecting their nest mates.
Francis Ratnieks, professor of apiculture at Sussex, one of the scientists involved in the study, said: "The discovery is significant in term of the evolution of advanced insect societies. Large-bodied soldier workers have long been known in ants and termites, but this is the first evidence of a soldier bee – a worker physically designed for active defence of their nest."
