Mimicking how the brain recognizes street scenes

...gineered to detect faces or recognize textures are poor at detecting cars. In the biological model, the same algorithm can learn to detect widely different types of objects. To test the model, the team presented full street scenes consisting of previously unseen examples from the Street Scene Database...

NT researchers discover breakthrough in malaria treatment

...unistically to people at high risk of infection in poor tropical communities." he added. A concern with such a policy is that the resistance will emerge quickly to the long acting drug. However the team believes that by combining the two drugs will help to prevent this from happening. ...

Discovery could lead to better control of hemorrhagic fever viruses

... World hemorrhagic fever outbreaks mostly occur in poor rural areas, where people are often deficient in micronutrients, including iron, possibly predisposing them to more severe infection when exposed to the rodents that carry the viruses. Choe's lab is now trying to find the cellular receptor for oth...

Peanut allergies overstated, study finds

Researchers use MRI to predict recovery after spinal cord injury

...leeding and cord swelling were key indicators of a poor prognosis after SCI. Conversely, the absence of these symptoms indicated a good chance for neurological recovery even if the injury otherwise appeared severe. "Since the severity of spinal cord compression is a predictor of outcome after SCI, this...

Warning from Asian bees

College students who pull 'all-nighters' and get no sleep more likely to have a lower GPA

...students is generally inadequate, irregular and of poor quality. As sleep quality and quantity decrease, academic performance worsens. The data collected in this study indicate that the use of a single night of total sleep deprivation is not an effective practice for achieving academic goals," said Pame...

Scientists consider the knowledge of evolutionary relationships, also called "phylogeny," to be fundamental to many fields of biology, including medicine, anatomy, physiology, ecology, ...

Pesticides choke pathway for nature to produce nitrogen for crops

Other reasons, Fox said, have been poor soil quality due to overuse, which strips nutrients such as nitrogen and phosphorous from the soil, and to tillage, which interrupts root structures and disturbs the nitrogen-fixing bacteria when soil is turned. "Our research provides another expl...
