An international team of researchers including scientists from The Australian National University have created a new, super-dense version of aluminium that could lead to efficient production of new super-hard nanomaterials at a relatively low cost. In a paper published today in Nature Communications, the group has described how they discovered a way to produce body-centred-cubic aluminium, which is 40 per cent more dense. Super-hard aluminium was predicted to exist more than 30 years ago but has never before been observed. Professor Andrei Rode from the Laser Physics Centre at ANU said the state of any material depends on temperature and pressure. “For example, water turns into ice ...

ScienceDaily (Aug. 24, 2011) — Coriander oil has been shown to be toxic to a broad range of harmful bacteria. Its use in foods and in clinical agents could prevent food-borne illnesses and even treat antibiotic-resistant infections, according to the authors of a study published in the Journal of Medical Microbiology. The researchers from the University of Beira Interior in Portugal tested coriander oil against 12 bacterial strains, including Escherichia coli, Salmonella enterica, Bacillus cereus and meticillin-resistant Staphylococcus aureus (MRSA). Of the tested strains, all showed reduced growth, and most were killed, by solutions containing 1.6% coriander oil or less. Coriander ...

ScienceDaily (Mar. 23, 2011) — Norwegian researcher Gro Amdam has succeeded in reversing the aging process in the bee brain -- findings which she believes may bring hope to people with dementia. "No one really believes that the fountain of youth exists," says Professor Amdam. "We accept that as we age, our health and mental acuity will decline. But recent findings indicate that aging doesn't have to be synonymous with going downhill." Professor Amdam's research subjects are bees, the workings of whose brain cells are surprisingly similar to ours, she explains. So when she finds the secrets behind what makes a bee brain tick, the knowledge may well apply ...

New test to identify which (heart) patients should take statins
Post Date: 2011-08-24 01:18:12 by Tatarewicz

Thousands of patients could be needlessly taking statins even though they are at low risk of suffering heart attacks or stroke, research suggests. Scientists say they have found a much better way to work out which people are in danger of developing heart problems. Half of the middle-aged adults they studied were found to have no coronary artery calcium, and only a handful of them went on to suffer a heart attack or a stroke. They say the findings have “important public health implications” and could mean large cost savings if the cholesterol-lowering drugs are prescribed only for those whose health would genuinely be improved by taking them. But other experts point out that ...

An international team of researchers has confirmed the presence of a newly discovered deep-ocean circulation system off Iceland that could significantly influence the ocean's response to climate change. The North Icelandic Jet contributes to a key component of the Atlantic Meridional Overturning Circulation, also known as the “great ocean conveyor belt,” which is critically important for regulating Earth’s climate, the scientists say. As part of the planet's reciprocal relationship between ocean circulation and climate, this conveyor belt carries warm surface water from the tropical Atlantic toward the Arctic. In the process, the water warms the air in high ...

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday. An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm. As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive. Scientists and doctors know that a sperm identifies an egg when proteins on the head ...

The chips can adapt to information that they weren't specifically programmed to expect They can potentially process real-world signals such as temperature, sound or motion and make sense of them The challenge in training a computer to behave like a human brain has tested the limits of science for decades. But researchers from IBM today said they have made a key step towards combining the two worlds. The U.S. technology firm has built two prototype chips that it says process data more like how humans digest information than the chips that currently power PCs and supercomputers. Looking to the future: IBM has developed two prototype chips it claims comes closer than ever to ...

BOSTON, Aug. 19, 2011 (Reuters) — Contact with extraterrestrials could be beneficial or might destroy the human race, according to an analysis of possible outcomes of an alien encounter that even one author of the study described as unlikely. The scenarios are contained in a paper written by a trio of scientists dated in April and published in the journal Acta Astronautica that won media attention this week following an article published in a British newspaper. The collection of possible outcomes, should earthlings meet beings from elsewhere, ranges from beneficial to harmful, according to the paper by Seth Baum, a doctoral candidate, and Jacob Haqq-Misra and Shawn Domagal-Goldman, ...

At last, we have sequenced the cannabis genome The Cannabis sativa genome has been sequenced by a team of scientists in Amsterdam (yes, really). The raw genetic sequence was posted yesterday to Amazon's EC2 cloud computing service by a company called Medicinal Genomics — just in time for the weekend. So what will we learn from weed DNA? Kevin McKernan, the founder of Medical Genomics, said the company's research was inspired by this 2003 publication in Nature Reviews Cancer, which examines the numerous therapeutic applications of cannabinoids — the active components of Cannabis sativa and its derivatives — including cancer treatments that could shrink tumors. ...

JIUQUAN, Gansu - China's experimental satellite, which was launched by the Long March II-C rocket Thursday, failed to enter the designated orbit due to a rocket malfunction. The rocket carrying the SJ-11-04 orbiter experienced problems during flight after it was launched from the Jiuquan Satellite Launch Center at 5:28 pm Beijing Time in Northwest China's Gansu province. Beijing News cited an unnamed military observer as saying the malfunction stopped the rocket from entering a planned altitude. "We don't know when the problem occurred, so it will be hard to find out the cause," the observer said, adding the orbiter may land in China's territory if the ...

ScienceDaily (Aug. 3, 2007) — Reading specialists have often pitted phonics against holistic word recognition and whole language approaches in the war over how to teach children to read. However, a new study by researchers at New York University shows that the three reading processes do not conflict, but, rather, work together to determine speed. The NYU study, by professor of psychology and neural science Denis Pelli and research scientist Katharine Tillman, measured the reading rates of 11 adult readers. It examined how three reading processes contribute to reading speed: 1) phonics, in which words are decoded letter by letter; 2) holistic word recognition, in which words are ...

— Word recognition behavior can be fine-tuned by experience and practice, according to a new study by Ian Hargreaves and colleagues from the University of Calgary in Canada. Their work shows, for the first time, that it is possible to develop visual word recognition ability in adulthood, beyond what researchers thought was achievable. Competitive Scrabble players provide the proof. The study is published online in Springer's journal Memory & Cognition. Competitive Scrabble involves extraordinary word recognition experience. Expert players typically dedicate large amounts of time to studying the 180,000 words listed in The Official Tournament and Club Word List. Hargreaves and ...

In recent years, former Vice President Al Gore has been the object of a great deal of humor — and ire — for his extremist views and hypocritical actions when it comes to the environment. But a bizarre rant from the man who was once heartbeats away from becoming President of these United States calls forth a term which Americans want nowhere near the Oval Office: unhinged. The ideology of manmade global warming has fallen on hard times in recent years due to a series of revelations that have fundamentally undermined the credibility of the “science” and its advocates. Beginning with “Climategate” and “Glaciergate” and continuing through such public ...

The death of the Sun to be accompanied with gigantic fireworks. 45090.jpegThe long-anticipated and widely discussed doomsday will come, but it is going to happen in approximately five billion years. The core of the Sun will run out of hydrogen by this time, and our celestial body will turn into a red giant. The star will then gradually turn into a white dwarf - the core of the Sun. Scientists from the University of Cambridge have recently presented the computer model of this process. When scientists say that the Sun can explode, common people mostly take such forecasts as absurdity. However, the Sun is not eternal. The Universe is not stable at all, and any of its bodies, including stars, ...
How cancer cells metastasize

Scientists have discovered how cancerous cells can "elbow" their way out of tumours, offering clues for new drugs to prevent cancers spreading. They say they have identified a protein called JAK which helps cancerous cells generate the force needed to move. Writing in Cancer Cell, they say the cells contract like muscle to force their way out and around the body. Cancer Research UK said the study provided fresh understanding of ways to stop cancer spreading. When cancers spread, a process known as metastasis, they become more difficult to treat, as secondary tumours tend to be more aggressive. It is thought that 90% of cancer-related deaths occur after metastasis. JAK attack ...

Scientists have discovered a natural preservative substance that keeps food fresh for years by destroying different food rotting bacteria. The agent called bisin is produced by harmless bacteria and has the capability of destroying a whole class of food decomposing germs including E-coli, salmonella and listeria. A team of researchers led by Dr. Dan O'Sullivan, an Irish microbiologist working with the University of Minnesota, isolated the substance from a culture of Bifodobacterium longum, a harmless bacterium commonly found in the human gut. The researchers claim that bisin can extend the life of many daily foods which have strict use-by dates including seafood, meat, eggs, dairy ...

Open source unemployment. Here is a very serious thought. As far as we know few people have written about it. Few have even thought about it. And no one has figured out what it means. But it could mean that the whole nature of the economy...and how we measure it...will have to change. More immediately, it is another cigarette for the wheezing Middle Class. The seed was planted by a headline from the Wall Street Journal. We didn't read the article. But we noticed the headline. "Porn industry profits down," or something like that. Hmmm.... surely, the demand had not decreased. We began to think about why the porn industry might be less profitable. We'll take a guess -- ...
