Carbon dioxide stored underground can find multiple ways to escape

Science Daily - Thu, 11/02/2016 - 11:59pm
When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to researchers.

Fish larvae are better off in groups, study finds

Science Daily - Thu, 11/02/2016 - 11:59pm
A recent study provides new evidence that larvae swim faster, straighter and more consistently in a common direction when together in a group. The research is the first to observe group orientation behaviors of larval fish.

A metal that behaves like water

Science Daily - Thu, 11/02/2016 - 11:59pm
Researchers have made a breakthrough in our understanding of graphene's basic properties, observing for the first time electrons in a metal behaving like a fluid. This research could lead to novel thermoelectric devices as well as provide a model system to explore exotic phenomena like black holes and high-energy plasmas.

Self-Propelling Microparticles Spot Ricin In Minutes

Slashdot - Thu, 11/02/2016 - 11:59pm
ckwu writes: Tiny rocketlike particles that move around on their own in a hydrogen peroxide solution can detect trace amounts of the lethal toxin ricin within minutes. The tube-shaped, microsized particles--made of graphene oxide lined with platinum--carry sensor molecules that glow when they bind to ricin. In a dilute hydrogen peroxide solution, the platinum catalyzes the breakdown of the peroxide into water and oxygen. The oxygen bubbles shoot out one end of the tube, propelling them in the liquid like little rockets. The swimming motors could actively seek out ricin in a sample and speed up detection, paving the way towards a quick, easy way to detect the bioterrorism agent in food and water samples (without having to bring them back to a lab).

Mommy and me: Study shows how affectionate mothering can combat the effects of maternal depression

Science Daily - Thu, 11/02/2016 - 11:50pm
Certain parenting strategies can combat the negative impacts of maternal depression on an infant, suggests the first study of its kind. The work sought to investigate how a depressed mother's neuroendocrine response to stress can program the infant's hypothalamic-pituitary-adrenal axis, a set of signals and relationships between the hypothalamus, the pituitary gland and the adrenals. The hypothalamic-pituitary-adrenal axis is responsible for creating cortisol, a hormone released in response to stress.

For a rare prairie orchid, science is making climate change local

Science Daily - Thu, 11/02/2016 - 11:50pm
A dynamic model that focuses on site scale conservation has been developed to give conservation decision-makers the capacity to assess multiple interacting stressors at the local scale, identify the most important stressors, and evaluate the efficacy of management strategies in light of their cumulative impacts.

Giving support to others, not just receiving it, has beneficial effects

Science Daily - Thu, 11/02/2016 - 11:49pm
Social support has well-known benefits for physical and mental health. But giving support -- rather than receiving it -- may have unique positive effects on key brain areas involved in stress and reward responses, suggests a new study.

Want to be a doctor, but have a disability? Many medical schools look unwelcoming

Science Daily - Thu, 11/02/2016 - 11:49pm
They may dream of becoming doctors, and helping people like themselves. But for young people with disabilities, that dream may die when they check the admissions standards of most medical schools, according to a new study.

New imaging technique shows how DNA is protected at chromosomes' ends

Science Daily - Thu, 11/02/2016 - 11:49pm
A new imaging technique has allowed researchers to see how DNA loops around a protein that aids in the formation of a special structure in telomeres. Telomeres are essentially caps on the ends of linear chromosomes, which are the structures inside our cells that contain DNA with our genetic information. In terms of function, telomeres are like the plastic coating (aglet) on the ends of shoelaces that prevents the laces from unraveling.
