Walking not enough for significant exercise benefits

...nsity activity such as walking alone is not likely going to give anybody marked health benefits compared to programs that occasionally elevate the intensity," said Dr. Vicki Harber, lead author on the Health First study, which was presented recently at the American College of Sports Medicine annual confere...

Serengeti patrols cut poaching of buffalo, elephants, rhinos

...has been able to reconstruct a history of poaching going back as far as 50 years, says Tom Hobbs, professor of ecology at Colorado State University and who is not affiliated with the work being published in Science. "The Hilborn team has shown that protection of wildlife by active enforcement of laws an...

New biochip helps study living cells, may speed drug development

... were flying in parabolas over the Gulf of Mexico, going from two times Earth's gravity to zero gravity again and again," he said. "There is absolutely no way this experiment could have been done without this chip." The current technology for analyzing cells' electrical activity, called "patch clamping,...

Detecting explosives with honeybees

...th research into why bees are such good detectors, going beyond merely demonstrating that bees can be used to identify the presence of explosives. By looking at such attributes as protein expression, the team sought to isolate genetic and physiological differences between those bees with good olfaction an...

How many genes does it take to learn? Lessons from sea slugs

...y of multiple genes in specific neurons. If we are going to understand memory or neurological disease at the cellular level, we need to understand the rules." Scientists also analyzed 146 human genes implicated in 168 neurological disorders, including Parkinson's and Alzheimer's diseases, and genes cont...

Recycled paper and compost could both be key tools to control plant disease

... have no other value. Obviously materials that are going to replace peat have to be very cheap or waste by-products. So, paper wastes fit this bill in terms of being cheap and they also hold a lot of water, which is what you need for plant growth". The suppression of plant diseases was particularly noti...

Scientists work to identify genes that contribute to early heart attack risk

...is the large number of genetic variants that we’re going to study," said Herrington. "Using special technology provided by Perlegen Sciences, we will examine more than 2 million different gene variations." In part two of the study, the scientists will work to confirm their findings by determining if any ...

UWM brain research supports drug development from jellyfish protein

... of many theories that attempts to explain what is going on in neuron degeneration. He became interested in aequorin as an undergraduate at UW-Milwaukee, after reading an article that linked the stings of jellyfish with the symptoms of multiple sclerosis, a disease of the central nervous system that his...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...medical Sciences at Hopkins. "The liver sure isn't going to tell you, it just keeps storing fat as long as the body is well fed." Instead, he notes, it is the control regions of the brain, namely the hypothalamus, that governs eating behavior. Previously, the same researchers showed that a molecule called...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

... of Michigan study gives new evidence about what's going on in the brain when we taste something we like, or develop a liking for something we once hated. And although the study used rats instead of people, it has direct implications for understanding the way we perceive pleasure ?and the reasons why som...

Major cancer study aims to identify protein markers for early-stage disease

... "We truly believe in this project, and that it is going to help people. We think that the methods we're proposing will work." The UCSF component of this research initiative will be carried out in two phases. Initially, scientists will study blood samples from mice that have been transplanted with human...

Fly's courtship sheds light on the formation of innate behaviors

... of neurons to the behaviors involved, and thereby going a long way in describing how the neural code for these behaviors is formulated in the developing fly's brain. This work, in conjunction with other studies performed by these and other research groups in recent years, shows how fundamentally important...

Evolutionary forces explain why women live longer than men

...ost women. "Because mortality rates in general are going down, behavioral causes of death are ever more prevalent," Kruger said. Looking at human mortality rates sliced by socioeconomic status shows that the gender gap is affected by social standing. Human males in lower socio-economic levels tend to hav...

"This research isn't so much about making people to live to 120 as it is about preventing diseases like diabetes, heart disease, or Alzheimer's. We're trying to identify the mechanisms that cause damage to our body as we age, and ...

UBC researchers find stroke death channel
