Special news section -- China's origins
Recent archaeological discoveries from far-flung corners of China are forcing scientists to reconsider the origins of ancient Chinese civilization -- and a new crop of young archaeologists are delving into the modern nation's roots. In the Aug. 21 issue of Science, a group of articles by Science news writer Andrew Lawler explore how the world's most populous and economically vibrant nation developed from the myriad peoples and cultures of the region over several millennia.

Blast-resistant rice
Some rice plants can fight off blast disease, a fungal infection that can devastate this globally important crop, and new research helps explain how these select rice plants have resisted the fungus for over a century of their cultivation, researchers report in the Aug. 21 issue of Science.

Study examines adverse events associated with human papillomavirus vaccine
An analysis of the adverse events reported following distribution of quadrivalent human papillomavirus recombinant vaccine since 2006 indicates that adverse event rates were consistent with pre-licensing data and expected background rates of other vaccines, with the exception of the higher frequency of cases of fainting and blood clots, according to a study in the August 19 issue of JAMA.

Palliative care intervention provides some benefits for patients with advanced cancer
Patients with advanced cancer who received a palliative care intervention focused on addressing physical and psychosocial issues and care coordination that was provided at the same time as cancer treatment reported improved quality of life and mood but did not experience a significant change in the number of days in the hospital or the severity of their symptoms compared to patients who received usual care, according to a study in the August 19 issue of JAMA.

Now butterflies are also being counted in China, Australia and Israel
In future, butterflies in the People's Republic of China are likely to be monitored using European monitoring methods. Ecologists from several Chinese research institutions and the Helmholtz Centre for Environmental Research laid the foundations for this cooperation on Friday. Experts from China, Germany, Australia and Israel met in Leipzig from August 10 to 14 to share their experiences in butterfly conservation and to intensify already existing research cooperations.

Facial expressions show language barriers too
People from East Asia tend to have a tougher time than those from European countries telling the difference between a face that looks fearful versus surprised, disgusted versus angry, and now a new report published online on Aug. 13 in Current Biology, a Cell Press publication, explains why. Rather than scanning evenly across a face as Westerners do, Easterners fixate their attention on the eyes.

How mother-of-pearl gets its pearliness
A Japanese research team has identified two proteins that act as traffic cops in growing oyster shells, directing calcium carbonate crystals to line up in a way that gives the shells their pearly luster, they report in the Aug. 14 issue of Science.

New orchid deception found: wearing the scent of hornet's prey
Orchids are famous for their deceptions. Most of those with nothing of value to offer their pollinators lure them instead with the scents of more rewarding flowers or potential mates. Now, a report published online on August 6th in Current Biology, a Cell Press publication, reveals for the first time that a species of orchid, which lives on the Chinese island of Hainan, fools its hornet pollinator by issuing a chemical that honeybees use to send an alarm.

A surprise player in chronic pain
Compounds called endocannabinoids, which have recently been enjoying the limelight as possible drug targets for everything from pain to obesity, can actually amplify certain pain signals rather than suppress them, as was previously thought, researchers report in the Aug. 7 issue of Science.

Researchers identify itch-specific neurons in mice, hope for better treatments
Researchers at Washington University School of Medicine in St. Louis have discovered that itch-specific neurons exist in mice, and their studies suggest that itch and pain signals are transmitted along different pathways in the spinal cord. The researchers say they can knock out an animal's itch response without affecting its ability to sense pain.
