Physicists offer theories to explain mysterious collision at Large Hadron Collider Posted: 08 Jan 2016 06:01 PM PST An unexpected bump in data from CERN's Large Hadron Collider is causing physicists to theorize about what caused it -- with potentially exciting results. Physicists are offering theories about what it could mean.

Researchers' metallic glue may stick it to soldering and welding Posted: 08 Jan 2016 05:57 PM PST Experts in nanotechnology have developed a glue that binds metal to metal to glass to you-name-it, sets at room temperature, and requires little pressure to seal.

How seashells get their strength Posted: 08 Jan 2016 05:09 PM PST Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A new study reveals how soft clumps get into crystals and endow them with remarkable strength.

Mechanical properties of nanomaterials are altered due to electric field Posted: 08 Jan 2016 05:09 PM PST Researchers for the first time have found that the electric field changes the fracture toughness of nanomaterials.

Anglers' gear, cooperation affect coral reef fisheries Posted: 08 Jan 2016 05:09 PM PST Scientists studying a Caribbean fishing village are shedding new light on the social and ecological factors pressuring coral reef fisheries around the world.

Airline passengers face longer delays under DOT rule, study finds Posted: 08 Jan 2016 05:09 PM PST It takes most air passengers far more time to reach their destination despite a federal rule that penalizes airlines for stranding them onboard during lengthy tarmac delays, a new study finds.

Key driver for treatment of deadly brain cancer Posted: 08 Jan 2016 05:09 PM PST A factor in how malignant tumors spread may also be a key to treatment.

New brief recommends increased insurance coverage for exercise programming for individuals with mental illness Posted: 08 Jan 2016 10:50 AM PST A new statement supporting increased coverage of exercise programming by health plans for individuals with mental illnesses has been released. The brief includes an assessment of current policies and recommends policy actions to state and federal policy makers, allied health professionals and state and federal mental health administrators.

Bite-mark analysis can lead to false convictions, landmark research shows Posted: 08 Jan 2016 10:49 AM PST Forensic science is a vital crime-fighting tool in today's criminal justice system. But it can also lead to false convictions, according to an expert, whose study proves that bite-mark analysis is "far from an exact science."

Retinal cells work with little reserve energy; may explain vulnerability to eye diseases Posted: 08 Jan 2016 10:48 AM PST Our eyes are especially demanding when it comes to energy: along with our brain, they require a substantial amount of power to keep them functioning and healthy. Now a new study suggests that because of their high-energy demands, our eyes function at high efficiency and with little reserve capacity, which scientists say may explain why they become vulnerable to degenerative diseases.

Research reveals advice given on internet health forums may not be as dangerous as often assumed Posted: 08 Jan 2016 10:46 AM PST New research suggests that medical advice given on internet health forums may be of better quality than people tend to assume.

Long-term observations hold key to climate change impact assessment Posted: 08 Jan 2016 10:46 AM PST Most ocean data sets are far too short for the accurate detection of trends resulting from global climate change, according to research. A new study will help to make decisions about where, and for how long, we should monitor the ocean in order to spot climate trends in ocean biology.

Researchers reveal mechanisms of how body remembers, fights infections Posted: 08 Jan 2016 10:43 AM PST Scientists have found a potential way to influence long-term memory formation in the immune system.

Visualizing atoms of perovskite crystals Posted: 08 Jan 2016 10:43 AM PST Researchers conduct the first atomic resolution study of perovskites used in next generation solar cells.

Risk taking across life span: The effects of hardship Posted: 08 Jan 2016 10:43 AM PST With increasing age, the propensity to take physical, social, legal or financial risks decreases. Researchers have now been able to show how factors such as poverty and income equality play a role.

The status quo on Europe's mussels Posted: 08 Jan 2016 10:42 AM PST Mussels are the natural treatment plants of bodies of water and, therefore, just as important as bees. Unfortunately, they are equally threatened: most of the world's mussel stocks are in decline and some species face extinction. For this reason, scientists from 26 European countries have compiled the first comprehensive survey on the status quo of freshwater mussel species.

Turning on the thyroid Posted: 08 Jan 2016 10:42 AM PST Despite the prevalence of thyroid disease and its sometimes serious effects, researchers have struggled to answer a pretty basic question about the hormone-producing gland: What turns it on? A new study provides an answer, and that answer was found within the gland itself.

Probing nuclear reactions in stars Posted: 08 Jan 2016 05:48 AM PST Thanks to a new experimental technique, scientists have now measured a crucial fusion reaction, involving hydrogen and a rare isotope of oxygen, that occurs inside stars.

How copper makes organic light-emitting diodes more efficient Posted: 08 Jan 2016 05:44 AM PST Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence (TADF) ensures high light yield. Scientists of Karlsruhe Institute of Technology (KIT), CYNORA, and the University of St Andrews have now measured the underlying quantum mechanics phenomenon of intersystem crossing in a copper complex. The results of this fundamental work are reported in the Science Advances journal and contribute to enhancing the energy efficiency of OLEDs.

Low-cost 3-D printer-based organ model production technique reveals complicated interior organ structure Posted: 08 Jan 2016 05:39 AM PST Researchers in Japan have successfully developed a low-cost human organ model production technique for use with 3-D printers that helps reveal complicated interior organ structure.
