Six-day clinical trial finds integrative medicine program alters blood serum Posted: 09 Sep 2016 07:34 PM PDT In a novel controlled clinical trial, participants in a six-day Ayurvedic-based well-being program that featured a vegetarian diet, meditation, yoga and massages experienced measurable decreases in a set of blood-based metabolites associated with inflammation, cardiovascular disease risk and cholesterol regulation.

Scientists expect to calculate amount of fuel inside Earth by 2025 Posted: 09 Sep 2016 06:48 AM PDT Scientists have developed numerous models to predict how much fuel remains inside Earth to drive its engines -- and estimates vary widely -- but the true amount remains unknown. In a new article, a team of geologists and neutrino physicists boldly claims it will be able to determine by 2025 how much nuclear fuel and radioactive power remain in the Earth's tank.

Physicists discover 'smoke rings' made of laser light Posted: 09 Sep 2016 06:48 AM PDT Physicists have discovered that self-focused laser pulses generate violent swirls of optical energy that resemble smoke rings. In these light structures, known as 'spatiotemporal optical vortices,' light energy flows through the inside of the ring and loops back around the outside. The vortices travel with the laser pulse and control energy flow around it.

Dances with waves: Breakthrough in moving small objects using acoustics Posted: 09 Sep 2016 06:48 AM PDT Researchers have made a breakthrough in controlling the motion of multiple objects on a vibrating plate with a single acoustic source. By playing carefully constructed melodies, the scientists can simultaneously and independently move multiple objects on the plate towards desired targets. This has enabled scientists, for instance, writing words consisting of separate letters with loose metal pieces on the plate by playing a melody.

Genome of the world's largest bony fish may explain fast growth rate and large size Posted: 08 Sep 2016 05:39 PM PDT The genome of the ocean sunfish, the world's largest bony fish, has been sequenced for the first time. The ocean sunfish genome revealed several altered genes that may explain the fast growth rate and large size of the fish as well as its unusual endoskeleton.

New immunotherapy treatment could lead to better, cheaper results for pancreatic cancer Posted: 08 Sep 2016 10:10 AM PDT A new immunotherapy treatment has shown dramatic results in treating advanced pancreatic cancer, a deadly cancer that has seen little progress in treatment over the last 20 years.

A more accurate sensor for lead paint Posted: 08 Sep 2016 10:10 AM PDT A new molecular gel recipe is at the core of a prototype for a more accurate lead paint test. The new test is more clear and accurate than its counterparts. It consists of a vial that holds paint thinner and a sprinkling of certain salts that, when combined with the right concentration of lead, form a gel.

Can some types of fat protect us from brain disease? Posted: 08 Sep 2016 10:08 AM PDT Having a little bit of extra fat may help reduce the risk of developing diseases caused by toxic protein aggregation, such as Huntington's, Parkinson's and Alzheimer's. Scientists have discovered a new communication process between organelles inside the cell, including mitochondria, and shown how fat metabolism plays a central role in linking mitochondrial health to cytosolic protein homeostasis. Another study uncovers a new signaling pathway that may explain the peripheral wasting seen in Huntington's.

Training human antibodies to protect against HIV Posted: 08 Sep 2016 10:06 AM PDT During HIV infection, the virus mutates too rapidly for the immune system to combat, but some people produce antibodies that can recognize the virus even two years after infection. With an eye towards developing a vaccine, in four related papers describe a multi-step method for 'training' the immune system to produce these antibodies in genetically engineered mice.

Male chemistry primes females for reproduction -- but at a cost Posted: 08 Sep 2016 10:06 AM PDT Scientist have discovered that male animals, through their invisible chemical 'essence,' prime female animals for reproduction but with the unfortunate side effect of also hastening females' aging process. The females sense the two signals and respond by altering their physiology. These findings in roundworms, which echo those made in mammalian studies, could lead to therapies that delay puberty and prolong fertility in humans as well as combat aging.

Tracing the path of pygmies' shared knowledge of medicinal plants Posted: 08 Sep 2016 10:05 AM PDT When members of the BaYaka Pygmies living in the northern Republic of Congo get sick, they don't just go to the doctor for a prescription. Instead, they rely on their shared knowledge of medicinal plants to help them get well. Now, researchers have examined shared uses of those plants to understand how Pygmies have passed their extensive plant knowledge along from one person to the next.

Feed a virus, starve a bacterial infection? Posted: 08 Sep 2016 10:05 AM PDT A new study puts some old folk wisdom to 'feed a cold and starve a fever' to the test. In mouse models of disease, Researchers looked at the effects of providing nutrients during infection and found opposing effects depending on whether the infections were bacterial or viral. Mice with bacterial infections that were fed died, while those with viral infections who were fed lived.

Study explores youths' motivations for painting graffiti Posted: 08 Sep 2016 09:09 AM PDT Youth who paint graffiti on businesses and public property, also called street taggers, say they don't view their actions as criminal because they are not injuring anyone and the graffiti can be easily erased, according to a new study.

Taking the momentum out of vibrations Posted: 08 Sep 2016 09:06 AM PDT Diesel engines vibrate. This produces tremendous stress on the components of ships. Adaptronic systems effectively reduce these vibrations. At the maritime trade fair researchers are presenting a simulation tool that allows these systems to be developed efficiently: The "Mechanical Simulation Toolbox" is now available on the market and easy to use.
