Up to 10% of adults living in developed countries fish for food and recreation and a new paper finds that in the Mediterranean Sea that could be up to 10% of the total production of fisheries - a large amount that is basically un-regulated outside buying a license. 

A small pilot study has shown that most of the children in a new oral immunotherapy treatment program were able to eat 100 grams of wheat bread without side effects, a promising way to mitigate the risk of accidental ingestion by people with this allergy. 

Microbiologists rarely wash their jeans. The reason is because they know how to keep the color looking new without getting odors - they freeze their pants. 

Freezing can even work in more extreme scenarios, like with waste water. 

When waste water freezes, it is purified through the formation of a cleaner layer of ice. Then the clean layer of ice can be removed from the rest of the waste water, and the remaining waste water is more concentrated, which can be treated as needed with a lot less outside processing. Energy is required only for breaking the ice and transporting it from the waste water pool.

The U.S. Food and Drug Administration recently warned that statins could affect the memory, attention span and other cognitive abilities of people who it drug to control high cholesterol.

Despite cultural claims in the US that the FDA is too liberal in approval, a new review found that they were instead being far too conservative. It was the precautionary principle becoming a vice, according to a systematic review of 25 clinical trials incorporating nearly 47,000 people, led by Brian R. Ott, M.D., professor at the Alpert Medical School of Brown University.

Long before oxytocin was the miracle spray that could make people feel more trusting, our ancestors used lavender. Unsurprisingly, it still works today, according to a new psychology paper.

Nederlandse Vereniging voor Psychonomie member psychologists Roberta Sellaro and Lorenza Colzato investigated whether the calming olfactory fragrance of lavender has a positive effect on mutual trust. Aromatherapists already knew that aromatic compounds can alter mood and even claim cognitive, psychological or physical wellbeing effects. “Mutual trust is the social glue of society,” says Sellaro. “Interpersonal trust is an essential element for social co-operation bargaining and negotiation.”

Within the nervous system there is a structure called the suprachiasmatic nucleus, a site considered as the biological clock in all mammals, including humans.

A new study has found that when this nucleus is damaged or destroyed the rhythm of the biological clock is lost.

Research by René Drucker and colleagues was performed in rats because they have well-defined activities at night that have little activity during the day. When some of these rats had neuronal alterations affecting their sleep cycle we could graph the amount of activity during the day and the night. So, when there was an injury that destroyed the suprachiasmatic nucleus, the pace and the biological clock was lost, and the animal equitably distributed its activity during the day and night.

Most vitamin supplements have little value to most people - if you can afford them your diet is probably already fine - but they have even less value in energy drinks and vitamin waters, despite how aggressively companies promote belief that they boost immune support and have antioxidant properties and whatever else.

Sensory 'hair cell' loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration - and hearing recovery - but the mechanisms that control their proliferation and hair cell regeneration are yet to be determined. 

A new study has shown that blocking the Notch pathway, known to control the elaborate hair cell distribution in the inner ear, plays an essential role that determines cochlear progenitor cell proliferation capacity.

(Inside Science) -- Showers fall to Earth’s surface as rain, snow, sleet or hail. But high in the clouds, water molecules often begin to come together as tiny ice crystals that form around miniscule particles of dust. The microscopic crystals are big players in creating rain and lightning, and also heat and cool the planet by bouncing sunlight off clouds.
