CODITA: measuring the cosmic dust swept up by the Earth
Although we think of space as being empty, there is more out there than meets the eye – dust, for example, is everywhere. If all the material between the Sun and Jupiter were compressed together it would form a moon 25 km across. Now a new research programme will try to see how much of this dust enters the Earth’s atmosphere. Metals from the cosmic dust play a part in various phenomena that affect our climate. An accurate estimate of dust would also help us understand how particles are transported through different layers of the Earth’s atmosphere. Professor John Plane of the University of Leeds will present the Cosmic Dust in the Terrestrial Atmosphere (CODITA) project on Friday 30 March at the National Astronomy Meeting in Manchester.

(PhysOrg.com) -- Coral off Tahiti has linked the collapse of massive ice sheets 14,600 years ago to a dramatic and rapid rise in global sea-levels of around 14 metres.

Recycling galaxies caught in the act
(PhysOrg.com) -- When astronomers add up all the gas and dust contained in ordinary galaxies like our own Milky Way, they stumble on a puzzle: There is not nearly enough matter for stars to be born at the rates that are observed. Part of the solution might be a recycling of matter on gigantic scales – veritable galactic fountains of matter flowing out and then back into galaxies over multi-billion-year timescales. 

Getting to know the Goldilocks planet
NASA's Kepler spacecraft is discovering a veritable avalanche of alien worlds.  Recent finds include planets with double suns, massive "super-Earths" and "hot Jupiters," and a miniature solar system.  The variety of planets circling distant suns is as wonderful as it is surprising.

Volcanic plumbing exposed
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions.

Declines in Caribbean coral reefs pre-date damage resulting from climate change
The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news – humans are still to blame. The good news – relatively simple policy changes can hinder further coral reef decline.

Organic compounds found in proto-planetary disks
(PhysOrg.com) -- A new study from scientists in the US has reported that organic compounds could be formed in proto-planetary disks, and could have seeded the development of life in our own and other planetary systems.

When dark energy turned on (Update)
Some six billion light years ago, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.

Simulations unravel mysteries of 2009 Jupiter impact
(PhysOrg.com) -- During July of 1994, both amateur and professional astronomers were captivated as comet Shoemaker/Levy 9 broke apart and slammed into the atmosphere of Jupiter. While these types of impacts are generally rare, a second impact event occurred fifteen years later in July of 2009. The object responsible for the 2009 impact was not directly observed, so astronomers could only make inferences about the object based on the disturbances in the Jovian atmosphere, as shown in the image above.

Technology news

The heat is on: New study of MIT buildings suggests additional approaches to energy efficiency
Many workplaces feature major changes in occupancy over the course of a week. In academic buildings, hundreds of students may pour in for a lecture, then leave an hour or two later, while faculty, researchers and staff can enter and exit in irregular patterns. In commercial structures, workers may come and go en masse during short time periods during the day. As a result, energy use in virtually all workspaces can rapidly become inefficient — too large or too small — in relation to the number of people inside.

Apple pledge likely to boost China factory wages
(AP) -- This week's pledge to trim work hours and effectively raise wages for the hardscrabble Chinese employees who assemble Apple's iPads and iPhones isn't likely to drive up the prices that consumers pay.

Tokyo-based computer security firm Trend Micro on Friday said it linked a hacker in China to a "cyber espionage" campaign targeting India, Japan, and Tibetans.

Cognitive researcher designs and builds a real-world modular working tricorder
(PhysOrg.com) -- To say it’s about copying the tricorder from Star Trek, of television and movie fame, is to belittle the ingenuity and thought that has gone into the devices that Peter Jansen has created; his tricorders, which were designed to look like the devices used by the TV characters, are both far more advanced and far less than their fictional counterparts. Far more, because unlike those represented on the silver screen, his actually work in real life. Far less, because its capabilities are still of the stone-age compared to those we see Captain Kirk or Picard and crew using to identify pretty much anything alien encountered at a moment’s notice.

Visa, MasterCard scramble after massive data breach
Credit card giants Visa and MasterCard were scrambling on Friday to thwart cyber crooks who looted a massive trove of precious account data, evidently from a payment processor in New York.

IOM report identifies public health actions for improving the lives of those with epilepsy
An estimated 2.2 million people in the United States live with epilepsy, a complex brain disorder characterized by sudden and often unpredictable seizures. The highest rate of onset occurs in children and older adults, and it affects people of all ethnicities and socio-economic backgrounds, yet this common disorder is widely misunderstood. Epilepsy refers to a spectrum of disorders with seizures that vary in type, cause, severity, and frequency. Many people do not know the causes of epilepsy or what measures to take if they witness a seizure. A new report from the Institute of Medicine highlights numerous gaps in the knowledge and management of epilepsy and recommends actions for improving the lives of those with epilepsy and their families and promoting better understanding of the disorder.

ADHD is over-diagnosed: German study
What experts and the public have already long suspected is now supported by representative data collected by researchers at Ruhr-Universität Bochum (RUB) and University of Basel: ADHD, attention deficit hyperactivity disorder, is over-diagnosed.

KU researcher developing synthetic patch to improve tracheal surgery
(Medical Xpress) -- Each year, thousands of newborns develop tracheal stenosis, a narrowing of the trachea that can make it difficult for them to breathe. While surgeons can fix this condition, the procedure requires reshaping the trachea and patching it with a piece of rib cartilage taken from the patient’s torso, which adds a level of complexity to the process.

A central regulator of the inflammatory response shows signs as a target for therapies against autoimmune disease
Some bacterial infections trigger the formation of structures known as granulomas, which essentially quarantine compromised cells. “Infected macrophages get surrounded by other immune cells, such as T cells and neutrophils,” explains Takashi Tanaka of the RIKEN Research Center for Allergy and Immunology in Yokohama. “This serves to wall off pathogens that resist destruction and limits their infection within a restricted area.”

Human attention to a particular portion of an image alters the way the brain processes visual cortex responses to that i
Our ability to ignore some, but not other stimuli, allows us to focus our attention and improve our performance on a specific task. The ability to respond to visual stimuli during a visual task hinges on altered brain processing of responses within the visual cortex at the back of the brain, where visual information is first received from the eyes. How this occurs was recently demonstrated by an international team of researchers led by Justin Gardner at the RIKEN Brain Science Institute in Wako, Japan.

Immune therapies: The next frontier in battle against atherosclerosis
New strategies injecting cardiovascular disease (CVD) patients with vaccines and monoclonal antibodies to combat atherosclerosis could soon change the treatment landscape of heart disease. Both approaches, Professor Jan Nilsson told delegates at the Frontiers in CardioVascular Biology (FCVB) 2012 meeting, can be considered truly ground breaking since for the first time they target the underlying cause of CVD. The FCVB meeting, organised by the Council on Basic Cardiovascular Science (CBCS) of the European Society of Cardiology (ESC), held 30 March to 1 April at the South Kensington Campus of Imperial College in London.

MRI and neuropsychological tests best predict Alzheimer's disease in old patients
Investigators from the University of Amsterdam, Netherlands, have shown that in most elderly patients invasive and expensive techniques, i.e. lumbar puncture and PET scan, are not useful to establish the diagnosis of Alzheimer's disease. They arrived at this conclusion after analysis of data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a large collaborative research project of medical centers in the USA and Canada.

The link between fast food and depression confirmed
According to a recent study headed by scientists from the University of Las Palmas de Gran Canaria and the University of Granada, eating commercial baked goods (fairy cakes, croissants, doughnuts, etc.) and fast food (hamburgers, hotdogs and pizza) is linked to depression.

Amyloid beta in the brain of individuals with Alzheimer's disease
While there may not be a consensus whether deposition of amyloid beta contributes to Alzheimer's disease or is a consequence of it, there is agreement that something else is promoting the process. Other proteins are often co-deposited with amyloid beta including serum amyloid P component. Recent evidence has suggested that SAP is elevated in Alzheimer's disease. Researchers from Keele University have shown that physiologically-significant concentrations of SAP promote the deposition of amyloid beta under conditions approaching those found in vivo.

Tales from the crypt lead researchers to cancer discovery
Tales from the crypt are supposed to be scary, but new research from Vanderbilt University, the HudsonAlpha Institute for Biotechnology and colleagues shows that crypts can be places of renewal too: intestinal crypts, that is. Intestinal crypts are small areas of the intestine where new cells are formed to continuously renew the digestive tract. By focusing on one protein expressed in our intestines called Lrig1, the researchers have identified a special population of intestinal stem cells that respond to damage and help to prevent cancer.
