Rosetta spacecraft arrives at comet destination Posted: 06 Aug 2014 04:12 AM PDT After a decade-long journey chasing its target, ESA's Rosetta has today become the first spacecraft to rendezvous with a comet, opening a new chapter in Solar System exploration. Comet 67P/Churyumov-Gerasimenko and Rosetta now lie 405 million kilometres from Earth, about half way between the orbits of Jupiter and Mars, rushing towards the inner Solar System at nearly 55,000 kilometres per hour.

Drug reverses brain deficits of Alzheimer's in mouse model Posted: 05 Aug 2014 12:08 PM PDT Researchers have discovered a new drug compound that reverses the brain deficits of Alzheimer's disease in an animal model. The compound, TC-2153, inhibits the negative effects of a protein called STtriatal-Enriched tyrosine Phosphatase (STEP), which is key to regulating learning and memory.

Just one simple question can identify narcissistic people Posted: 05 Aug 2014 12:06 PM PDT Scientists have developed and validated a new method to identify which people are narcissistic: just ask them. In a series of 11 experiments involving more than 2,200 people of all ages, the researchers found they could reliably identify narcissistic people by asking them one question.

Scientists introduce new cosmic connectivity: Quantum pigeonhole paradox Posted: 05 Aug 2014 10:25 AM PDT Recently physicists at Chapman University's Institute for Quantum Studies introduced the Quantum Cheshire Cat. Now they have introduced another quantum animal: the Quantum Pigeon. They introduced a new kind of quantum connectivity between particles which transcends these limitations. This connectivity is happening all the time on a much bigger, cosmic scale.

Common chemical in mothers may negatively affect the IQ of their unborn children Posted: 05 Aug 2014 10:25 AM PDT In some women, abnormally high levels of a common and pervasive chemical may lead to adverse effects in their offspring, researchers report. The study is the first of its kind to shed light on the possible harmful side effects of perchlorate in mothers and their children. "The reason people really care about perchlorate is because it is ubiquitous. It's everywhere," said one investigator. "Prior studies have already shown perchlorate, at low levels, can be found in each and every one of us."

Planet-like object may have spent its youth as hot as a star Posted: 05 Aug 2014 07:25 AM PDT Astronomers have discovered an extremely cool object that could have a particularly diverse history - although it is now as cool as a planet, it may have spent much of its youth as hot as a star. The current temperature of the object is 100-150 degrees Celsius, intermediate between that of the Earth and Venus. But the object shows evidence of a possible ancient origin, implying that a large change in temperature has taken place.

Bottling up sound waves: Acoustic bottle beams hold promise for imaging, cloaking, levitation and more Posted: 04 Aug 2014 12:15 PM PDT Researchers have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories. These self-bending bottle beams hold promise for ultrasonic imaging and therapy, and acoustic cloaking, levitation and particle manipulation.

Flores bones show features of Down syndrome, not a new 'Hobbit' human Posted: 04 Aug 2014 12:15 PM PDT In October 2004, excavation of fragmentary skeletal remains from the island of Flores in Indonesia yielded what was called 'the most important find in human evolution for 100 years.' Its discoverers dubbed the find Homo floresiensis, a name suggesting a previously unknown species of human.

Massive volcanic outbursts on Jupiter's moon Io: More common than thought? Posted: 04 Aug 2014 11:10 AM PDT Three massive volcanic eruptions occurred on Jupiter's moon Io within a two-week period in August of last year. This led astronomers to speculate that such "outbursts," which can send material hundreds of miles above the surface, might be much more common than they thought.

No-power Wi-Fi connectivity could fuel Internet of Things reality Posted: 04 Aug 2014 10:42 AM PDT Engineers have designed a new communication system that uses radio frequency signals as a power source and reuses existing Wi-Fi infrastructure to provide Internet connectivity to battery-free devices.

Extracting audio from visual information: Algorithm recovers speech from vibrations of a potato-chip bag filmed through soundproof glass Posted: 04 Aug 2014 07:05 AM PDT Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.

Implanted neurons become part of the brain, mouse study shows Posted: 04 Aug 2014 07:01 AM PDT Scientists have grafted neurons reprogrammed from skin cells into the brains of mice for the first time with long-term stability. Six months after implantation, the neurons had become fully functionally integrated into the brain. This successful, lastingly stable, implantation of neurons raises hope for future therapies that will replace sick neurons with healthy ones in the brains of Parkinson's disease patients, for example.

New material allows for ultra-thin solar cells Posted: 04 Aug 2014 03:59 AM PDT Extremely thin, semi-transparent, flexible solar cells could soon become reality. Scientists have managed to create a semiconductor structure consisting of two ultra-thin layers, which appears to be excellently suited for photovoltaic energy conversion. Several months ago, the team had already produced an ultra-thin layer of the photoactive crystal tungsten diselenide. Now, this semiconductor has successfully been combined with another layer made of molybdenum disulphide, creating a designer-material that may be used in future low-cost solar cells.

Atlantic warming turbocharges Pacific trade winds Posted: 03 Aug 2014 04:36 PM PDT Rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. This has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific and has slowed the rise of global average surface temperatures since 2001.

'Active' surfaces control what's on them: Scientists develop treated surfaces that can actively control how fluids or particles move Posted: 01 Aug 2014 07:50 AM PDT Researchers have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic devices, or solar panels that could automatically clean themselves of dust and grit.

Political attitudes derive from body and mind: 'Negativity bias' explains difference between liberals and conservatives Posted: 31 Jul 2014 11:59 AM PDT Neither conscious decision-making or parental upbringing fully explain why some people lean left and others lean right, researchers say. A mix of deep-seated psychology and physiological responses are at the core of political differences.

Charging electric cars efficiently with inductive method Posted: 31 Jul 2014 06:47 AM PDT We already charge our toothbrushes and cellphones using contactless technology. Researchers have developed a particularly efficient and cost-effective method that means electric cars could soon follow suit.

Otzi Iceman had genetic predisposition for atherosclerosis: Much the same in ancient peoples as it is today Posted: 30 Jul 2014 05:37 PM PDT While prevalence and types of risk factors for atherosclerosis have varied over time from ancient times to modern society -- such as levels of obesity, physical activity -- genetic predisposition/risk for the condition today appears to be very similar to that in ancient times.

Try, try again? Study says no: Trying harder makes it more difficult to learn some aspects of language, neuroscientists find Posted: 21 Jul 2014 11:22 AM PDT Neuroscientists find that trying harder makes it more difficult to learn some aspects of language. When it comes to learning languages, adults and children have different strengths. Adults excel at absorbing the vocabulary needed to navigate a grocery store or order food in a restaurant, but children have an uncanny ability to pick up on subtle nuances of language, sometimes speaking a second language like a native speaker within months. Brain structure plays an important role in this "sensitive period" for learning language, which is believed to end around adolescence.

Blue-eyed Humans Have A Single, Common Ancestor Posted: 30 Jan 2008 02:03 PM PST New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.
