An all-natural sunscreen derived from algae

2015-07-29
For consumers searching for just the right sunblock this summer, the options can be overwhelming. But scientists are now turning to the natural sunscreen of algae -- which is also found in fish slime -- to make a novel kind of shield against the sun's rays that could protect not only people, but also textiles and outdoor materials. They report on their development in the journal ACS Applied Materials & Interfaces. Existing sunblock lotions typically work by either absorbing ultraviolet rays or physically blocking them. A variety of synthetic and natural compounds can ...

End-of-production LED lighting increases red pigmentation in lettuce

2015-07-29
WEST LAFAYETTE, IN - Growing vegetables in greenhouses extends crop production seasons in northern latitudes, but the greenhouse environment is far from ideal for providing plants with optimal photosynthetic light. In fact, available photosynthetic daily light in greenhouses can be reduced by up to 50% or more by the structures' glazing material, superstructure, and shading. In northern latitudes, low light is considered the most limiting environmental factor in greenhouse vegetable production. For example, low light levels can result in the formation of loose heads and ...

Toward a safe antiobesity drug that could block fat absorption

2015-07-29
To help address the global obesity epidemic, scientists are developing a new class of compounds called "micelle sequestrant polymers," or MSPs, that could prevent fat particles from getting absorbed in the body and thus potentially reduce weight gain. They report on their novel agents, which they tested on mice, in the ACS journal Biomacromolecules. Research has shown that worldwide, obesity rates have been climbing for years. Treatments for overweight and obesity include diet and exercise, surgery and prescription medications. But currently available drugs can have serious ...

Malic acid encourages sweet cherry cracking

2015-07-29
HANNOVER, GERMANY -- "Cracking" is a problem for sweet cherry production wherever the high-value crop is grown. However, despite considerable research, the reason that this phenomenon occurs has not been clear. In a new study, Andreas Winkler, Max Ossenbrink, and Moritz Knoche reveal their discovery of what makes sweet cherries crack. Knoche, lead author of the study published in the Journal of the American Society for Horticultural Science, said the scientists from the Institute for Horticultural Production Systems at Leibniz University set out to investigate consequences ...

Figuring out how to make tastier wines using fewer pesticides

2015-07-29
Wine-making is steeped in age-old traditions, but to address the threat of pests and concerns over heavy pesticide use, vintners are turning to science. With the goal of designing better grape breeds, scientists are parsing the differences between wild American grapes -- which make terrible wine but are pest-resistant -- and the less hardy grape species pressed for fine wines worldwide. They report their findings in ACS' Journal of Agricultural and Food Chemistry. With every sip of their preferred drink, wine lovers from across the globe are appreciating the taste of ...

Shoring up Tor

2015-07-29
With 2.5 million daily users, the Tor network is the world's most popular system for protecting Internet users' anonymity. For more than a decade, people living under repressive regimes have used Tor to conceal their Web-browsing habits from electronic surveillance, and websites hosting content that's been deemed subversive have used it to hide the locations of their servers. Researchers at MIT and the Qatar Computing Research Institute (QCRI) have now demonstrated a vulnerability in Tor's design. At the Usenix Security Symposium this summer, they show that an adversary ...

Compliance with guidelines for treating brain injuries doesn't guarantee better outcomes

2015-07-29
Two decades ago, the Brain Trauma Foundation published its first set of guidelines for treating traumatic brain injury. Now, a study by the Los Angeles County Trauma Consortium -- which includes several physicians from UCLA -- has found that compliance with those guidelines doesn't necessarily translate into better results for patients. In research published online by the peer-reviewed journal JAMA Surgery, the consortium analyzed 2009 and 2010 data from all 14 L.A. County trauma centers and found no evidence that compliance with the guidelines led to lower mortality ...

Barrow scientists 'rewrite' history books

2015-07-29
Researchers at Barrow Neurological Institute have spent years of medical sleuthing across three continents to uncover a brain surgery that changed history. After more than two-years of international investigation, the scientists have concluded that Napoleon likely would have conquered Russia in 1812 if not for the life-saving brain surgery performed on Russian general Mikhail Kutuzov by the French surgeon Jean Massot, who operated on Kutuzov after bullets twice passed through his head. "It's a story of how medicine changed the course of civilization," says Mark C. Preul, ...

Basis for new treatment options for a fatal leukemia in children revealed

2015-07-29
Berlin, 29th July 2015 - Acute lymphoblastic leukemia (ALL) is the most common type of cancer in children. It can occur in various forms, differing not only by specific changes in the genetic material of the leukemia cells but also by their response to therapies. Now, an international team of scientists from Berlin, Düsseldorf, Hannover, Heidelberg, Kiel, and Zurich have succeeded in decoding the molecular characteristics of an as yet incurable subtype of leukemia, paving the way for new therapeutic approaches. Their results have been published in the current issue ...

Social groups and emotions

2015-07-29
Politicians, children, teachers, Europeans... what do they have in common? As discovered in a study led by Luca Piretti and his colleagues from SISSA (International School for Advanced Studies) of Trieste, they are all social groups, a special semantic category for the human brain that is closely linked with emotions. Until recently, most neuroscientists believed that the representation of knowledge in the brain was based on two distinct systems: one involved in representing animate objects (or, generally, anything organic), and the other for representing inanimate objects ...
