The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.

Scientists have tricked bone marrow into releasing extra adult stem cells into the bloodstream, a technique that they hope could one day be used to repair heart damage or mend a broken bone, in a new study published today in the journal Cell Stem Cell.

In 1913 Theodore Roosevelt added cartographer to his resume when he and his crew ventured up an unspeakably dangerous and uncharted tributary named the River of Doubt. Now, on a charting expedition of their own, Rockefeller University scientists have completed a journey that has also defied expectation. In work to be published in the January 9 issue of Cell, the team reports the discovery of a new family of receptors in the fly nose, a finding that not only fills in a missing piece in the organizational logic of the insect olfactory system but also unearths one of the most ancient mechanisms that organisms have evolved to smell.

In ant society, workers normally give up reproducing themselves to care for their queen's offspring, who are their brothers and sisters. When workers try to cheat and have their own kids in the queen's presence, their peers swiftly attack and physically restrain them from reproducing.

Scientists have identified the structure of a key component of the bacteria behind such diseases as whooping cough, peptic stomach ulcers and Legionnaires' disease. The research, funded by the Wellcome Trust and the Biotechnology and Biological Sciences Research Council (BBSRC), sheds light on how antibiotic resistance genes spread from one bacterium to another. The research may help scientists develop novel treatments for these diseases and novel ways to curtail the spread of antibiotic resistance.

Oxytocin, a hormone involved in child-birth and breast-feeding, helps people recognize familiar faces, according to new research in the January 7 issue of The Journal of Neuroscience. Study participants who had one dose of an oxytocin nasal spray showed improved recognition memory for faces, but not for inanimate objects.

Ten years ago, the Chinese National Human Genome Center at Shanghai (South Center, hereafter) was established in the Zhangjiang HiTech Park of Pudong District in Shanghai. To commemorate this important event, which marks the beginning of the Genomics Era in China, we specially organize a series of mini-reviews for this special issue. We hope that this effort may draw the attention of the Chinese life science research workers to collectively recall the short but fruitful history of human genome project and coordinately explore the trend and goal of the future development of this academic discipline in China.

The novel design of a deep muscle along the spinal column called the multifidus muscle may in fact be key to spinal support and a healthy back, according to researchers at the University of California, San Diego School of Medicine. Their findings about the potentially important "scaffolding" role of this poorly understood muscle has been published on line in advance of the January issue of the Journal of Bone and Joint Surgery.

Influenza's ability to resist the effects of cheap and popular antiviral agents in Asia and Russia should serve as a cautionary tale about U.S. plans to use the antiviral Tamiflu in the event of widespread avian flu infection in humans, scientists say.
