Pollution threatens coral health by preventing lesions from healing, UCF study shows

... mouth of the Hillsborough Inlet and control sites away from outfalls and inlets. Fauth and his colleagues used the equivalent of blood tests on humans to identify likely causes of low coral vitality near wastewater discharge pipes and the Port Everglades inlet. Coral that were growing near both areas ...

Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

Sticky surfaces turn slippery with the flip of a molecular light switch

...ticky proteins to detach from the surface and wash away in the liquid, the researchers report. Not only is the switching mechanism uncomplicated, but so is the patented procedure required to graft spiropyran molecules to poly(ether sulfone). "We used a relatively simple two-step process that could be eas...

Tiny airborne particles are a major cause of climate change

...les affect weather systems thousands of kilometers away from their sources. There is no doubt that aerosols do play a role, but the skeptics believe it is negligible compared to meteorological key players such as temperature, pressure, the amount of water vapor in the air, and wind strength. What Koren ...

For diseases, when it comes to sharing a home, only close relatives will do

...the hosts," adds Koskella. To win host resources away from a non-relative, theory assumes the pathogens will increase exploitation of the host and thus cause more severe symptoms. However, if pathogens share the host most often with close relatives, this evolutionary conflict is decreased, possibly resu...

Neurons grown from embryonic stem cells restore function in paralyzed rats

... the GDNF-treated limbs and to take steps and push away with the foot on that side of the body. "This research represents significant progress," says David Owens, Ph.D., the NINDS program director for the grant that funded the work. "It is a convergence of embryonic stem cell research with other areas of...

Seeing the serpent

...ou really need to see close up. If it's a long way away it's not dangerous," Isbell said. Neurological studies by others show that the structure of the brain's visual system does not actually fit with the idea that vision evolved along with reaching and grasping, Isbell said. But the visual system does ...

Rehydrate -- your RNA needs it

...ng protein targets, ultimately keeping the protein away from where it can wreak havoc," Walter said. "So the fundamental understanding we are gaining of the role of water in RNA almost certainly will have relevance in the treatment or prevention of disease." ...

UCLA scientists strengthen case for life more than 3.8 billion years ago

.... "We've been holding our fire rather than fire away at each criticism in a piecemeal way," he said. "We've gone back to Greenland and done the study from the ground up, with much more data than existed at the time of the original paper. I'm much more confident today than I was in 1996 about the likeli...

NASA technology helping injured US troops

...d, a rare disease that afflicted his spine, taking away all of his lower body muscle strength. The condition, which developed after his military service, caused his knees to buckle during physical therapy. "The SAM walker prevented my knees from buckling and helped me regain my mobility. I was able to ...

Toxic molecule may cause most common type of muscular dystrophy

...c dystrophy," Mahadevan said. "Then, when you take away the toxic RNA, the mice get back to normal." Mahadevan hopes the research might lead to new therapies for MMD in the next few years. "If we develop a therapy to silence the expression of the toxic RNA molecule, that would be a viable approach to tre...

Device effective in zapping the pain out of migraines

An electronic device designed to "zap" away migraine pain before it starts may be the next form of relief for millions of people who suffer from the debilitating disease. Results of a study found that the experimental device appears to be effective in eliminating the headache when administer...

Finding a better way to make biodiesel

Larry Breeding, the general manager of biodiesel operations for the West Central Cooperative, said the technology shows promise for improving the efficiency of biodiesel production. But he said it still needs to be tested at larger and l...

How plants avoid feeling the burn

...University. Carotenoids act as 'wires' to carry away the extra sunlight energy in the form of unwanted electrons, somehow wicking away the extra electrons across long distances from locations that could damage plant tissues and photosy...

Queensland scientists identify molecule that links both sides of the brain

...dentify a growth molecule that guides young nerves away from the corpus callosum and towards their targets in the opposite hemisphere," Dr Cooper said. "We have shown that the Ryk receptor molecule facilitates the targeting of individual nerve fibres. "This process is critical for the transmission of ...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...ly "on" during both fasting and feeding might melt away fat depots. And that's exactly what happened. Mice genetically engineered to express permanently elevated levels of TRB3 protein in fat tissue were 10-20 percent skinnier than normal mice. "Even when we put them on a high-fat diet, these mice just d...

Tiny shock absorbers help bacteria stick around inside the body

...is exerted on a bacterium. Rather than being swept away by fluids moving through the human body, the bacterium grips even more tightly, helping it stick around and form an infection, like those seen in the urinary tract, for instance. The catch bonds release their grip when there is little or no force on ...

But that green color wasn't an indication of health, it was an indication of stress from a lack of iron." The study i...

Even fish don't swim well when they're young!

...nd a few feeble strokes of doggy-paddle propel you away from your parent's arms. Surely, you think, fish must be born as expert swimmers. Actually, fish larvae are pretty feeble when it comes to an efficient mode of swimming called 'burst-and-coast'. Dr Ulrike Müller from Wageningen University studies how...
