Controlling genes with your thoughts Posted: 11 Nov 2014 08:13 AM PST Researchers have constructed the first gene network that can be controlled by our thoughts. Scientists have developed a novel gene regulation method that enables thought-specific brainwaves to control the conversion of genes into proteins (gene expression). The inspiration was a game that picks up brainwaves in order to guide a ball through an obstacle course.

Archaeologists discover remains of Ice Age infants in Alaska Posted: 10 Nov 2014 01:11 PM PST The remains of two Ice Age infants, buried more than 11,000 years ago at a site in Alaska, represent the youngest human remains ever found in northern North America, according to a new article.

Marijuana's long-term effects on the brain demonstrated Posted: 10 Nov 2014 01:11 PM PST The effects of chronic marijuana use on the brain may depend on age of first use and duration of use, according to new research. Researchers for the first time comprehensively describe existing abnormalities in brain function and structure of long-term marijuana users with multiple magnetic resonance imaging (MRI) techniques.

Cat genome reveals clues to domestication​​ Posted: 10 Nov 2014 01:10 PM PST Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome reveals some surprising clues.

Thousands of never-before-seen human genome variations uncovered Posted: 10 Nov 2014 09:42 AM PST Thousands of never-before-seen genetic variants in the human genome have been uncovered using a new genome sequencing technology. These discoveries close many human genome mapping gaps that have long resisted sequencing. The technique, called single-molecule, real-time DNA sequencing, may now make it possible for researchers to identify potential genetic mutations behind many conditions whose genetic causes have long eluded scientists.

Moderate drinking is healthy only for some people, study finds Posted: 10 Nov 2014 06:07 AM PST A new study confirms that moderate alcohol consumption can protect against coronary heart disease. But only for the 15% of the population that have a particular genotype.

Astronomers dissect the aftermath of a supernova Posted: 10 Nov 2014 05:33 AM PST Astronomers have used radio telescopes in Australia and Chile to see inside the remains of a supernova. The supernova, known as SN1987A, was first seen by observers in the Southern Hemisphere in 1987 when a giant star suddenly exploded at the edge of a nearby dwarf galaxy called the Large Magellanic Cloud. In the two and a half decades since then the remnant of Supernova 1987A has continued to be a focus for researchers the world over, providing a wealth of information about one of the Universe's most extreme events.

Transitions between states of matter: It’s more complicated, scientists find Posted: 06 Nov 2014 11:35 AM PST The seemingly simple process of phase changes -- those transitions between states of matter -- is more complex than previously known. New work reveals the need to rethink one of science's building blocks and, with it, how some of the basic principles underlying the behavior of matter are taught in our classrooms.

Having a Y chromosome doesn't affect women's response to sexual images, brain study shows Posted: 05 Nov 2014 01:52 PM PST Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.
