Grapefruit juice stems weight gain in mice fed a high-fat diet, study finds

Posted: 08 Oct 2014 12:36 PM PDT

Mice fed a high-fat diet gained 18 percent less weight when they drank clarified, no-pulp grapefruit juice compared with a control group of mice that drank water, a new study demonstrated. Juice-drinking mice also showed improved levels of glucose, insulin and a type of fat called triacylglycerol compared with their water-drinking counterparts.

Amputees discern familiar sensations across prosthetic hand

Posted: 08 Oct 2014 12:36 PM PDT

Patients connected to a new prosthetic system said they 'felt' their hands for the first time since they lost them in accidents. In the ensuing months, they began feeling sensations that were familiar and were able to control their prosthetic hands with more -- well -- dexterity.

Mind-controlled prosthetic arms that work in daily life are now a reality

Posted: 08 Oct 2014 12:36 PM PDT

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.

Bronze age palace and grave goods discovered at the archaeological site of La Almoloya in Pliego, Murcia

Posted: 08 Oct 2014 07:14 AM PDT

Archaeologists have discovered a palatial construction with an audience hall which makes up the first specifically political precincts built in continental Europe. A prince's tomb in the subsoil contains the largest amount of grave goods from the Bronze Age existing in the Iberian Peninsula. Some of the most outstanding items include a silver diadem of great scientific and patrimonial value, the only one conserved from that era in Spain, as well as four golden and silver ear dilators.

2014 Nobel Prize in Chemistry: Super-resolved fluorescence microscopy

Posted: 08 Oct 2014 05:54 AM PDT

The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig of Janelia Farm Research Campus, Howard Hughes Medical Institute; Stefan W. Hell of Max Planck Institute for Biophysical Chemistry and the German Cancer Research Center; and William E. Moerner of Stanford University "for the development of super-resolved fluorescence microscopy."

How dinosaurs divided their meals at the Jurassic dinner table

Seven Swedish women have had embryos reintroduced after receiving wombs from living donors. Now the first transplanted woman has delivered a baby – a healthy and normally developed boy.

Ocean warming in Southern Hemisphere underestimated, scientists suggest

Posted: 06 Oct 2014 06:45 AM PDT

Using satellite observations and a large suite of climate models, scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated. Ocean heat storage is important because it accounts for more than 90 percent of Earth's excess heat that is associated with global warming.

Nanoparticles break the symmetry of light

Posted: 06 Oct 2014 05:49 AM PDT

How can a beam of light tell the difference between left and right? Tiny particles have now been coupled to a glass fiber. The particles emit light into the fiber in such a way that it does not travel in both directions, as one would expect. Instead, the light can be directed either to the left or to the right. This has become possible by employing a remarkable physical effect – the spin-orbit coupling of light. This new kind of optical switch has the potential to revolutionize nanophotonics.

Air pollution increases river flows, study shows

Posted: 05 Oct 2014 10:49 AM PDT

Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, a new study shows. The paper shows how such pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change.

New method for detecting water on Mars

Posted: 03 Oct 2014 03:45 AM PDT

An undergraduate student has helped develop a new method for detecting water on Mars. Water is a key indicator for the potential of microbial life on the red planet. While reseachers didn't see evidence of it from two sites they studied, their method could look for water elsewhere.
