Molecular 'pulleys' improve battery performance

Jul 20 2017

Scientists have reported a molecular pulley binder for high-capacity silicon anodes of lithium ion batteries.

Paying people to protect forests is worth it

Jul 20 2017

A new study suggests that paying people to conserve their trees could be a highly cost-effective way to reduce deforestation and carbon emissions and should be a key part of the global strategy to fight climate change. The study sought to evaluate how effective 'Payments for Ecosystems' (PES) is at reducing deforestation.

Faulty support cells disrupt communication in brains of people with schizophrenia

Jul 20 2017

New research has identified the culprit behind the wiring problems in the brains of people with schizophrenia. When researchers transplanted human brain cells generated from individuals diagnosed with childhood-onset schizophrenia into mice, the animal's nerve cell networks did not mature properly and the mice exhibited the same anti-social and anxious behaviors seen in people with the disease.

Genetic predisposition to breast cancer due to non-BRCA mutations in Ashkenazi Jewish women

Jul 20 2017

Genetic mutations in BRCA1 and BRCA2 increase the risk of breast and ovarian cancer in Ashkenazi Jewish women. A new article pexamines the likelihood of carrying another cancer-predisposing mutation in BRCA1, BRCA2 or another breast cancer gene among women of Ashkenazi Jewish ancestry with breast cancer who do not carry one of the founder mutations.

Laser treatment reduces eye floaters

Jul 20 2017

Patients reported improvement in symptoms of eye floaters after treatment with a laser, according to a new study.

Is mental health associated with perception of nasal function?

Jul 20 2017

A study of preoperative patients for rhinoplasty suggests poor mental well-being and low self-esteem were associated with poorer perceptions of nasal function, according to a new study.

Use of cognitive abilities to care for grandkids may have driven evolution of menopause

Jul 20 2017

Instead of having more children, a grandmother may pass on her genes more successfully by using her cognitive abilities to directly or indirectly aid her existing children and grandchildren. Such an advantage could have driven the evolution of menopause in humans.

Google searches can be used to track dengue in underdeveloped countries

Jul 20 2017

An analytical tool that combines Google search data with government-provided clinical data can quickly and accurately track dengue fever in less-developed countries.

Elephant seals recognize each other by the rhythm of their calls

Jul 20 2017

Every day, humans pick up on idiosyncrasies such as slow drawls, high-pitched squeaks, or hints of accents to put names to voices from afar. This ability may not be as unique as once thought, researchers report. They find that unlike all other non-human mammals, northern elephant seal males consider the spacing and timing of vocal pulses in addition to vocal tones when identifying the calls of their rivals.

Crustal limestone platforms feed carbon to many of Earth's arc volcanoes

Jul 20 2017

A new analysis suggests that much of the carbon released from volcanic arcs, chains of volcanoes that arise along the tectonic plates of a subduction zone, comes from remobilizing limestone reservoirs in the Earth's crust.

Fear of arrest stops some needed calls to 911 after opioid overdose is administered

Jul 18 2017

Fear of being arrested still undercuts an Indiana law that shields anyone who administers naloxone from criminal charges, according to a survey. Naloxone is a lifesaving emergency antidote for opioid overdose.

When sizing up potential friends and mates, the eyes of men and women move differently

Jul 18 2017

Where do your eyes linger when judging a person for potential friendship? New research shows that people observe the body differently when assessing friends versus mates.

Making lab equipment on the cheap

Jul 18 2017

Laboratory equipment is one of the largest cost factors in neuroscience. However, many experiments can be performed with good results using self-assembled setups involving 3-D printed components and self-programmed electronics. Researchers have now created 'FlyPi' -- a low-cost imaging and microscope system for research, training and teaching.

Testosterone prescribing in VA varies by provider's age, experience, specialty and region

Jul 18 2017

Providers in the Veterans Health Administration (VA) system vary in their testosterone prescribing practices, according to a new study.

At the cellular level, a child's loss of a father is associated with increased stress

Jul 18 2017

The absence of a father -- due to incarceration, death, separation or divorce -- has adverse physical and behavioral consequences for a growing child. But little is known about the biological processes that underlie this link between father loss and child well-being. In a new study, a team of researchers reports that the loss of a father has a significant adverse effect on telomeres, the protective nucleoprotein end caps of chromosomes.
