Scientists sniff out female mouse scents that make males frisky?? Posted: 14 Nov 2015 03:52 PM PST Scientists have identified two chemical scents in the urine of female mice that arouse sexual behavior in males, a discovery that shines a spotlight on how mouse pheromones control behavior.

Researchers call for next chapter in improving patient safety by reducing misdiagnosis Posted: 14 Nov 2015 03:52 PM PST Approximately 12 million people in the United States experience diagnostic errors annually, but it is time for a change, according to experts, who say that by reducing misdiagnosis, patient safety is measurably improved.

Injection instead of laser may be viable treatment option for diabetic retinopathy Posted: 14 Nov 2015 03:50 PM PST Among patients with proliferative diabetic retinopathy, treatment with an injection in the eye of the drug ranibizumab resulted in visual acuity that was not worse than panretinal photocoagulation at two years, according to a study.

One-step test for hepatitis C virus infection developed Posted: 14 Nov 2015 03:50 PM PST A cost-effective one-step test that screens, detects and confirms hepatitis C virus (HCV) infections has been developed by researchers. Current blood-based HCV testing requires two steps and can be expensive, inconvenient and is not widely available or affordable globally.

Parkinson drug may prevent, delay AMD Posted: 13 Nov 2015 03:25 PM PST A significant discovery has been made that might lead to the delay or prevention of the most common cause of blindness in the elderly: age-related macular degeneration (AMD). Patients who take the drug L-DOPA (for Parkinson Disease, Restless Legs or other movement disorders) are significantly less likely to develop AMD and, if they do, it is at a significantly later age.

Building with nature: Ecological design for next-generation cities Posted: 13 Nov 2015 03:13 PM PST New research celebrates the centennial of the society with perspectives on the potential for ecological science to influence the design of the next generation cities and their infrastructure.

3-D printing aids in understanding food enjoyment Posted: 13 Nov 2015 03:13 PM PST Tasting food relies on food volatiles moving from the back of the mouth to the nasal cavity, but researchers have wondered why airflow doesn't carry them in the other direction, into the lungs. Now a team of engineers, using a 3-D printed model of the human airway from nostril to trachea, has determined that the shape of the airway preferentially transfers volatiles to the nasal cavity and allows humans to enjoy the smell of good food.

20 million tweets used to understand people and real-world situations Posted: 13 Nov 2015 03:13 PM PST What can you tell about people and their situations from only 140 characters? Quite a lot according to a new study about Twitter. To date, no research has tapped the vast data from social media to study situations. Using more than 20 million tweets, researchers provide insights about the psychological experience of a typical workday or week, and reveal the psychological characteristics of real-world situations that people actually experienced over the course of two weeks.

Cyclin' out of gear: Malaria parasites grinding to a halt Posted: 13 Nov 2015 03:13 PM PST Scientists have uncovered the role of cyclin -- the protein molecule that drives the growth of malaria within mosquitoes. The research could pave the way to better understanding of how the malaria parasite thrives and lead to potential new treatments.

Online abuse affects three in five Australians, study shows Posted: 13 Nov 2015 07:57 AM PST Three in five Australians have been the target of online harassment and abuse, new research reveals. Women and young adults are most likely to report being sexually harassed online, while one in 10 adults said someone had shared a nude or semi-nude image of them without their consent.

Photons on a chip set new paths for secure communications Posted: 13 Nov 2015 07:56 AM PST Researchers have cracked the code to ultra-secure telecommunications of the future in an international research project that could also expedite the advent of quantum computing.

Zig while others zag for more successful investments Posted: 13 Nov 2015 02:15 AM PST Aso-called contrarian investment funds far outperform their herd-fund rivals in several performance measurements, new research shows, adding that their managers have found ways to gather information that other managers haven't figured out.

High durability, efficiency of 1 cm2 size perovskite solar cells Posted: 13 Nov 2015 02:13 AM PST A research group has improved the power conversion efficiency (PCE) of perovskite solar cells to over 16% while employing cells that were greater than 1 cm2. The high efficiency cells also passed the durability test (exposure to AM 1.5G 100 mW/cm2 sunlight for 1,000 hours), which is considered to be a basic criterion for practical use. These achievements were made by replacing the conventional organic materials with inorganic materials as the electron and hole extraction layers of the solar cells.

Male bees have more than a one-track mind Posted: 13 Nov 2015 02:09 AM PST Male bumblebees are believed to have few aptitudes beyond mating and thought to be not just lazy but simple. In comparison, for example, worker bees are well known to learn the location of their hive, the colors and scents of rewarding flowers. However, male bumblebees are just as smart as female worker bees despite their dim-witted reputation, according to new research.

Oceans, ocean activism, deserve broader role in climate change discussions Posted: 12 Nov 2015 12:59 PM PST Researchers argue that both ocean scientists and world leaders should pay more attention to how communities are experiencing, adapting to and even influencing changes in the world's oceans.
