NOAA's Space Weather Prediction Center is the official U.S Government source for space weather forecasts, alerts, watches and warnings. NASA and NOAA,as well as the US Air Force Weather Agency (AFWA) and others, keep a constant watch on the sun to monitor for space weather effects such as geomagnetic storms, the idea being that with advance notification many satellites, spacecraft and technologies can be protected from the worst effects.
 

A component of egg whites, already a popular whole egg substitute among cholesterol-conscious consumers concerned, may have another beneficial effect - reducing blood pressure, according to a study presented earlier this week at the American Chemical Society (ACS) meeting. 

The researchers used a peptide called RVPSL. Scientists previously discovered that the substance, like the family of medications that includes Captopril, Vasotec and Monopril, was an angiotensin-converting-enzyme (ACE) inhibitor. It has the ability to inhibit or block the action of ACE, a substance produced in the body that raises blood pressure.

Almost everyone who has had an arm or leg amputated experiences a phantom limb, a vivid sensation that the missing limb is still present, like having an itch.

Neuroscientists at the Karolinska Institutet in Sweden have shown that it isn't just for amputees - the sensation of having a physical body is not as self-evident as we might think and have evoked the illusion of having a phantom hand in non-amputated individuals.

Brain studies are a mass of contradictions. When you leave your job and your home and your technology behind for a vacation, you 'disconnect' some claim.

"Actually, you've just given your brain a whole new challenge," says Thomas D. Albright, director of the Vision Center Laboratory at of the Salk Institute and an expert on how the visual system works. "You may think you're resting, but your brain is automatically assessing the spatio-temporal properties of this novel environment-what objects are in it, are they moving, and if so, how fast are they moving?

The Environmental Protection Agency has always been a political beast - it is political appointees accountable to whatever administration is in power, not the electorate. President Richard Nixon created it, that should tell you something.

Scientists in the UK, Portugal and Germany solved the structure of kynurenine 3-monooxygenase (KMO), a protein implicated in the neurodegeneration (destruction of nerve cells) seen in diseases associated with old age, such as Alzheimer’s, Parkinson’s and Huntington’s.

 It also reveals how to block KMO in a major first step to develop a promising new therapeutic approach for a group of diseases that, despite affecting millions worldwide, remain without cure or treatment. 

Researchers recently studied the reaction of aphids when a parasitic wasp with genetic variation laid eggs in them and found that different genotypes of the wasp affected where the aphids went to die, including whether they left the plant host entirely. The team also found an example of the emergence of a shared phenotype that was partly wasp and partly aphid.

A traditional Balkan bedbug remedy has been shown stab and trap the biting insects, according to a paper in the Journal of the Royal Society Interface.

Just in time, too. Bedbugs have made a dramatic comeback in the U.S. in recent years, infesting everything from homes and hotels to schools, movie theaters and hospitals. Although not known to transmit disease, their bites can cause burning, itching, swelling and psychological distress. It helps to catch infestations early, but the nocturnal parasites' ability to hide almost anywhere, breed rapidly and "hitchhike" from place to place makes detection difficult. They can survive as long as a year without a blood meal.

Male and female birds often show differences in body size, with males typically being larger. Some birds, like many ratites – large, flightless species such as emus and cassowaries – are the opposite, with the females towering over the males. 

But some extinct ratites, among the largest female birds in the world, were almost twice as big as their male mates. A new paper says that the size difference in giant moa was not due to any specific environmental factors but instead evolved as a result of scaling-up of smaller differences in male and female body size shown by their smaller-bodied ancestors.

New research has questioned the reliability of neuroscience studies, concluding that most had an average power of around 20 percent – a finding which means the chance of the average study discovering the effect being investigated is only one in five. 

The conclusions neuroscience papers drew could be wrong due to small sample sizes, the authors say.
