Putting bedbugs to bed forever

Posted: 24 Dec 2014 07:31 AM PST

A team of scientists has found a way to conquer the global bedbug epidemic. By lending their own arms for thousands of bed bug bites, they have finally found the solution -- a set of chemical attractants, or pheromones, that lure the bedbugs into traps, and keep them there.

Activating hair growth by modifying immune cells

Posted: 23 Dec 2014 01:11 PM PST

How to restore hair loss is a task not undertaken exclusively by beauty practitioners. The discover reveals a novel angle to spur hair follicle growth. This also adds new knowledge to a broader problem: how to regenerate tissues in an adult organism, especially the skin.

Could playing Tchaikovsky's 'Nutcracker' and other music improve kids' brains?

Posted: 23 Dec 2014 10:25 AM PST

In a study called 'the largest investigation of the association between playing a musical instrument and brain development,' a child psychiatry team has found that musical training might also help kids focus their attention, control their emotions and diminish their anxiety.

Molecular mechanism behind health benefits of dietary restriction identified

Posted: 23 Dec 2014 09:22 AM PST

A key molecular mechanism behind the health benefits of dietary restriction has been identified by researchers. Also known as calorie restriction, dietary restriction is best known for its ability to slow aging in laboratory animals. The findings here show that restricting two amino acids, methionine and cysteine, results in increased hydrogen sulfide (H2S) production and protection against ischemia reperfusion injury, damage to tissue that occurs following the interruption of blood flow as during organ transplantation and stroke.

That smartphone is giving your thumbs superpowers

Posted: 23 Dec 2014 09:22 AM PST

When people spend time interacting with their smartphones via touchscreen, it actually changes the way their thumbs and brains work together, according to a new report. More touchscreen use in the recent past translates directly into greater brain activity when the thumbs and other fingertips are touched, the study shows.

How electrons split: New evidence of exotic behaviors

Posted: 23 Dec 2014 08:42 AM PST

Electrons split into electrical charge and magnetic moment in a two-dimensional model, a study has shown for the first time. The discovery marks a new understanding in the discovery of exotic materials such as high-temperature superconductors.

Hunt for Big Bang particles offering clues to the origin of the universe

Posted: 23 Dec 2014 08:38 AM PST

Billions upon billions of neutrinos speed harmlessly through everyone's body every moment of the day, according to cosmologists. The bulk of these subatomic particles are believed to come straight from the Big Bang, rather than from the sun or other sources. Experimental confirmation of this belief could yield seminal insights into the early universe and the physics of neutrinos. But how do you interrogate something so elusive that it could zip through a barrier of iron a light-year thick as if it were empty space?

Weight training appears key to controlling belly fat

Posted: 23 Dec 2014 05:39 AM PST

Healthy men who did 20 minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, according to a new study. Combining weight training and aerobic activity led to the most optimal results. Aerobic exercise by itself was associated with less weight gain compared with weight training.

Existing drug, riluzole, may prevent foggy 'old age' brain, research shows

Posted: 22 Dec 2014 08:19 AM PST

Forgetfulness, it turns out, is all in the head. Scientists have shown that fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and already on the market as a treatment for ALS, may help prevent these changes.

New technology makes tissues, someday maybe organs

Posted: 22 Dec 2014 08:16 AM PST

A new device for building large tissues from living components of three-dimensional microtissues borrows on ideas from electronics manufacturing. The Bio-Pick, Place, and Perfuse is a step toward someday making whole organs.

The dementia that is not Alzheimer's disease

Posted: 19 Dec 2014 01:04 PM PST

The term Alzheimer's is frequently used to describe all dementias even though there are many different causes for dementia. Lewy body dementia affects 1.4 million American and is frequently misdiagnosed, experts report.

A vegetarian carnivorous plant

Posted: 19 Dec 2014 07:40 AM PST

Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains.

OCD patients' brains light up to reveal how compulsive habits develop

Posted: 19 Dec 2014 05:51 AM PST

Misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder, according to researchers.

Homing signal in brain located, explaining why some people are better navigators

Posted: 18 Dec 2014 10:14 AM PST

The part of the brain that tells us the direction to travel when we navigate has been identified by scientists, and the strength of its signal predicts how well people can navigate. In other words, the researchers have found where our 'sense of direction' comes from in the brain and worked out how to measure it using functional magnetic resonance imaging, fMRI.

Archaeologists unearth royal entry complex at Herodian Hilltop Palace

Posted: 18 Dec 2014 09:07 AM PST

Archaeologists have unearthed a unique royal entryway to the Herodian Hilltop Palace. The main feature is a 20-meter-high corridor with a complex system of arches, allowing the King and his entourage direct passage into the palace courtyard.  During the excavations, the original palace vestibule, decorated with painted frescoes, was also exposed.
