Many of the genes involved in natural repair of the injured spinal cord of a fish called the lamprey are also active in the repair of the peripheral nervous system in mammals, according to a new study. Lampreys are jawless, eel-like fish that shared a common ancestor with humans about 550 million years ago. They [...]
Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.
While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress.
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.
According to Charles Darwin the ability to adapt to new conditions is essential for survival of species. The capacity to cope with altered conditions is becoming increasingly important in the face of climate change. New evidence on salt water tolerance in spawning migrating pike from the Baltic Sea suggests that not being adapted to specific local environments may promote persistence in an uncertain, rapidly changing world.
On average, former elite athletes survive longer than their brothers. In addition, their self-rated health and health-related habits are better in comparison to their brothers at an older age. The study included in total 900 former elite athletes and their brothers.
Researchers have found a new way of halting the growth of breast cancer cells. The researchers explored a new way to starve cancer cells from their molecular energy source. They hope that their discoveries can be further developed into a new way of treating breast cancer, and possibly other types of cancer.
Many drugs work by inhibiting protein enzymes associated with a particular disease. Unfortunately, the same drugs can inhibit protein enzymes unrelated to the disease, resulting in harmful side effects. A team of computational biologist has developed a way to identify the features that distinguish one enzyme from similar enzymes. This research has the potential to significantly accelerate drug discovery, allowing scientists to develop more effective drugs, more quickly.
The milliDelta robot integrates a new microfabrication technique with high-performance composite materials that can incorporate flexural joints and bending actuators, the milliDelta can operate with high speed, force, and micrometer precision, which make it compatible with a range of micromanipulation tasks in manufacturing and medicine.
Chances are someone in your life causes a lot of tension and stress. Difficult relationships are common and hard to evade. New research suggests that difficult people are likely to be found in contexts where people have less freedom to pick and choose their associates. Often it's family and co-workers - people you're stuck with, either because you need them or because you can't ignore them -- making it difficult to cut the cord.
To a mantis shrimp, walking away from a fight doesn't mean being a wimp. It means recognizing who they're up against and knowing when to bail rather than drag out a doomed battle, researchers say. Mantis shrimp use sparring matches to decide when to fight and when to fold.
Despite increasing numbers of underrepresented minority (URM) trainees in the biomedical sciences, there is a persistent shortage of URM faculty who are involved in basic biomedical research at medical schools. Investigators examined the entire training pathway of potential faculty candidates to identify points of greatest loss of URM trainees. Two key points of loss: during undergraduate education and in transition from postdoctoral fellowship to tenure-track faculty.
Using the power of Japan's K computer, scientists have shown that incorporating satellite data at frequent intervals -- 10 minutes in the case of this study -- into weather prediction models can significantly improve the rainfall predictions of the models and allow more precise predictions of the rapid development of a typhoon.
