Robots get a feel for the world: Touch more sensitve than a human's

Posted: 18 Jun 2012 04:49 PM PDT

What does a robot feel when it touches something? Little or nothing until now. Specially designed robots can now be equipped with a sense of touch even more sensitive than that of humans.

Landsat sets the standard for maps of world's forests

Posted: 18 Jun 2012 04:49 PM PDT

Countries like Brazil are using data from NASA satellites to track and measure their forests in advance of a United Nations effort to reduce climate change by providing "carbon credits" for protected land. The concept is known as REDD+, which stands for Reducing Emissions from Deforestation and Forest Degradation. It includes monitoring forest degradation and efforts in conservation and sustainable management.

Posted: 18 Jun 2012 12:37 PM PDT

Scientists have turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all.

Brothers in arms: Commensal bacteria help fight viruses

Posted: 18 Jun 2012 12:34 PM PDT

These microbial partners provide beneficial aid in multiple ways -- from helping digest food to the development of a healthy immune system. New research shows that commensal bacteria are essential to fight off viral infections.

May 2012 global temperatures second warmest on record

Posted: 18 Jun 2012 12:27 PM PDT

The globally-averaged temperature for May 2012 marked the second warmest May since record keeping began in 1880. May 2012 also marks the 36th consecutive May and 327th consecutive month with a global temperature above the 20th century average.

Dating evidence: Relics could be of John the Baptist

Posted: 18 Jun 2012 12:12 PM PDT

New dating evidence supports claims that bones found under a church floor in Bulgaria may be of John the Baptist, who is described in the Bible as a leading prophet and relative of Jesus Christ. Scientists dated a knucklebone from the right hand to the 1st century AD, a date which fits with the widely held view of when he would have lived. The researchers say they were surprised when they discovered the very early age of the remains adding, however, that dating evidence alone cannot prove the bones to be of John the Baptist.

'Facebook for animals' tested on wild great tits

Posted: 18 Jun 2012 12:00 PM PDT

New findings demonstrate that there are small effects of radiation even at very low doses.

Million-year-old groundwater in Maryland water supply

Posted: 18 Jun 2012 10:31 AM PDT

A portion of the groundwater in the upper Patapsco aquifer underlying Maryland is over a million years old. A new study suggests that this ancient groundwater, a vital source of freshwater supplies for the region east of Washington, DC and Baltimore, was recharged over periods of time much greater than human timescales.

Key part of plants' rapid response system revealed

Posted: 18 Jun 2012 10:29 AM PDT

Scientists have revealed the workings of a switch that activates plant hormones, tags them for storage or marks them for destruction.

Peaches, plums, nectarines give obesity, diabetes slim chance

Posted: 18 Jun 2012 10:29 AM PDT

Peaches, plums and nectarines have bioactive compounds that can potentially fight-off obesity-related diabetes and cardiovascular disease, according to new studies.

Carbon is key for getting algae to pump out more oil

Posted: 18 Jun 2012 08:18 AM PDT

Overturning two long-held misconceptions about oil production in algae, scientists show that ramping up the microbes' overall metabolism by feeding them more carbon increases oil production as the organisms continue to grow. The findings may point to new ways to turn photosynthetic green algae into tiny "green factories" for producing raw materials for alternative fuels.

Reflected infrared light unveils never-before-seen details of Renaissance paintings

Posted: 18 Jun 2012 08:18 AM PDT

When restoring damaged and faded works of art, artists often employ lasers and other sophisticated imaging techniques to study intricate details, analyze pigments, and search for subtle defects not visible to the naked eye. To refine what can be seen during the restoration process even further, a team of Italian researchers has developed a new imaging tool that can capture features not otherwise detectable with the naked eye or current imaging techniques.

Particle physics: BaBar data hint at cracks in the Standard Model

Posted: 18 Jun 2012 08:18 AM PDT

Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, a high-energy physics experiment, show that a particular type of particle decay called "B to D-star-tau-nu" happens more often than the Standard Model says it should.

Children, brain development and the criminal law

Posted: 18 Jun 2012 07:28 AM PDT

The legal system needs to take greater account of new discoveries in neuroscience that show how a difficult childhood can affect the development of a young person's brain which can increase the risk adolescent crimes, according to researchers.

Study improves understanding of surface molecules in controlling size of gold nanoparticles

Posted: 18 Jun 2012 07:28 AM PDT

Researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles – with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.

Black holes as particle detectors

Posted: 18 Jun 2012 07:28 AM PDT

Black holes could serve as particle detectors, say scientists. Axions, a hypothetical but not improbable kind of particles, could accumulate around a black hole, creating a "boson cloud". After some time, this boson cloud would collapse, sending out characteristic gravity waves.

Yankee Fans keep enemy Red Sox closer

Posted: 18 Jun 2012 07:26 AM PDT

Fans of the New York Yankees incorrectly perceive Fenway Park, home of the archrival Boston Red Sox, to be closer to New York City than is Camden Yards, home of the Baltimore Orioles, psychologists have found. Their research shows how social categorization, collective identification, and identity threat work in concert to shape our representations of the physical world.

The weight of nations: An estimation of adult human biomass

Posted: 18 Jun 2012 06:50 AM PDT

The world population is over seven billion and all of these people need feeding. However, the energy requirement of a species depends not only on numbers but on its average mass. New research has estimated the total mass of the human population, defined its distribution by region, and the proportion of this biomass due to the overweight and obesity.

Seeping Arctic methane has serious implications for Florida coastline

Posted: 18 Jun 2012 06:50 AM PDT

Controlling hand movements : Manipulation of specific neural circuit buried in complicated brain networks in primates

Posted: 17 Jun 2012 11:25 AM PDT

Scientists have developed "the double viral vector transfection technique," which can deliver genes to a specific neural circuit by combining two new kinds of gene transfer vectors. With this method, they found that "indirect pathways," which were suspected to have been left behind in the course of evolution, actually plays an important role in the highly developed dexterous hand movements.
