The first steps towards developing a vaccine against an insidious sexual transmitted infection (STI) have been accomplished.
Using data collected from Baihe, one of the largest dating websites in China, researchers developed a reciprocal recommendation system that better matches users who are mutually interested in and likely to communicate with each other. The data revealed behavioral differences between male and female users when it comes to contacting potential partners. In particular, males tend to be focused on their own interests and be oblivious toward their attractiveness to potential dates, while females are more conscious of their own attractiveness.
The ability to predict when toads come out of hibernation in southern Canada could provide valuable insights into the future effects of climate change on a range of animals and plants.
An international research team is working to understand how horseshoes affect foot skeleton stress in racehorses, in a project that is likely to benefit the racing industry and protect horses from injury.
In western North America, mountain pine beetles infest and ravage thousands of acres of forest lands. Landsat satellites bear witness to the onslaught in a way that neither humans nor most other satellites can.
International research has found how plants, such as rice and wheat, sense and respond to extreme drought stress, in a breakthrough that could lead to the development of next-generation drought-proof crops.
Researchers have developed a novel technique to address the problem of vision-based face detection and recognition under normal and severe illumination conditions. This technique contributes to help robotic systems that use face information for providing user-dependent services to work well under a large variety of illumination conditions.
Study offers a new solution to prevent Bronchopulmonary Dysplasia (BPD), the most common chronic lung disease in premature infants.
A new study of nearly 22,000 fossils finds that ancient plankton communities began changing in important ways as much as 400,000 years before massive die-offs ensued during the first of Earth's five great extinctions. The research suggests that the effects of environmental degradation can be subtle until they reach a tipping point, at which dramatic declines in population begin.
Patients suffering from liver cirrhosis often die of life-threatening bacterial infections. In these patients the immune cells are unable to eliminate the bacterial infections. Scientist have now discovered that type I IFN released by immune cells due to increased migration of gut bacteria into the cirrhotic liver incapacitate the immune system. Based on their findings, such infections can be contained by strengthening the immune response -- without antibiotics.
Ants employ a few simple and flexible rules to ensure that moving a colony to a new nest does not end in chaos, especially if this is done over some distance. A new study indicates that when it comes to giving directions, ants have it down to a fine art.
The ability to switch disease-causing genes on and off remains a dream for many physicians, research scientists and patients. Researchers have now programmed a virus to transport the necessary genetic material to affected tissue and nerve cells inside the body.
An international consensus demands human impacts on the environment 'sustain', 'maintain', 'conserve', 'protect', 'safeguard', and 'secure' it. But, policy makers have little idea what these terms mean or how to connect them to a wealth of ecological data and ideas.
Obesity is a well-known risk factor for osteoarthritis, but its effects on cartilage repair are unknown. In a recent study in a mouse model of cartilage repair, a high fat diet and increased body weight did not negatively impair cartilage repair, and it could even accelerate it.
Older people in Japan are more resistant to the impacts of disasters on their health than younger generations, a study suggests.
Adding sulphonylureas (SUs) to metformin remains a commonly used strategy for treating type 2 diabetes, but individual SUs differ and may confer different risks of abnormally low blood sugar, or hypoglycemia. SUs -- which include newer generation agents such as gliclazide, glipizide, glimepiride, and glibenclamide -- stimulate the production of insulin in the pancreas and increase the effectiveness of insulin in the body.
An unprecedented record of erosion rates dating back millions of years shows a significant time-lag between tectonic uplift and maximum erosion rates in the Argentine Precordillera mountains. According to a new study, tectonic shortening and exhumation of rocks peaked between twelve and nine million years ago whereas the maximum erosional response is detected roughly seven million years ago, i.e. two million years later.
Scientists have developed software that allows observing cells for weeks while also measuring molecular properties. The software is freely available.
With the rapid advance of miniaturization, data processing using electric currents faces tough challenges, some of which are insurmountable. Magnetic spin waves are a promising alternative for the transfer of information in even more compact chips. Scientists have now succeeded in generating spin waves with extremely short wavelengths in the nanometer range -- a key feature for their future application.
Bullying happens in the primate world too, but for young bonobo females, big mama comes to the rescue. Kyoto University primatologists report that bonobo females frequently aid younger females when males behave aggressively towards them. This partly explains how females maintain a superior status in bonobo society.
