Seven tiny grains captured by Stardust likely visitors from interstellar space Posted: 14 Aug 2014 04:19 PM PDT The 1999 Stardust mission flew by comet Wild-2 in 2004, capturing cometary and interstellar dust, and delivered its dust-loaded collectors to Earth in 2006. Scientists now report preliminary results of their eight-year analysis of the interstellar particles: seven dust motes that likely originated in another solar system less than 100 million years ago. The particles are more diverse than expected, and fluffier, like a tossed salad.

Plants may use newly discovered molecular language to communicate Posted: 14 Aug 2014 04:19 PM PDT A scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another. The finding throws open the door to a new arena of science that explores how plants communicate with each other on a molecular level. It also gives scientists new insight into ways to fight parasitic weeds that wreak havoc on food crops in some of the poorest parts of the world.

A self-organizing thousand-robot swarm Posted: 14 Aug 2014 04:18 PM PDT The first thousand-robot flash mob has assembled at Harvard University. Just as trillions of individual cells can assemble into an intelligent organism, or a thousand starlings can form a great flowing murmuration across the sky, the Kilobots demonstrate how complexity can arise from very simple behaviors performed en masse. To computer scientists, they also represent a significant milestone in the development of collective artificial intelligence.

Fukushima's legacy: Biological effects of Fukushima radiation on plants, insects, and animals Posted: 14 Aug 2014 09:45 AM PDT Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds.

Early antibiotic exposure leads to lifelong metabolic disturbances in mice Posted: 14 Aug 2014 09:34 AM PDT Antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body's metabolism, setting up a predisposition to obesity, according to a new study. Moreover, the research shows that it is altered gut bacteria, rather than the antibiotics, driving the metabolic effects.

Estimated 1.65 million global cardiovascular deaths each year linked to high sodium consumption Posted: 13 Aug 2014 02:36 PM PDT More than 1.6 million cardiovascular-related deaths per year can be attributed to sodium consumption above the World Health Organization's recommendation of 2.0 grams per day, researchers have found in a new analysis of populations across 187 countries.

Tick-tock: How to quite literally speed up a woman's biological clock Posted: 13 Aug 2014 10:21 AM PDT The metaphor of a ticking clock is often used to refer to a woman's growing urge -- from puberty onwards to menopause -- to conceive before her childbearing years are over. New research shows that there's more truth to this phrase than you might think. "The very subtle sound prime of a ticking clock changed the timing with which women sought to have children and the traits they sought in potential partners -- both central aspects of women's mating-related psychology," says one researcher.

Cell discovery brings blood disorder cure closer Posted: 13 Aug 2014 10:21 AM PDT A cure for a range of blood disorders and immune diseases is in sight, according to scientists who have unraveled the mystery of stem cell generation. Found in the bone marrow and in umbilical cord blood, HSCs are critically important because they can replenish the body's supply of blood cells. Leukemia patients have been successfully treated using HSC transplants, but medical experts believe blood stem cells have the potential to be used more widely.

Temporary tattoo biobatteries produce power from sweat Posted: 13 Aug 2014 07:31 AM PDT In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers have designed a sensor in the form of a temporary tattoo that can both monitor a person's progress during exercise and produce power from their perspiration.

Evidence Links Cocaine Abuse And Parkinson's Disease Posted: 14 Dec 2005 05:48 AM PST Adults who abuse cocaine might increase their risk of developing Parkinson's disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life, according to results of laboratory studies performed by investigators at St. Jude Children's Research Hospital.
