Slowing the insect invasion: Wood packaging sanitation yields US $11.7 billion net benefit Posted: 23 May 2014 04:24 PM PDT The emerald ash borer, a recent insect immigrant to North America carried in with the wooden packing material of imported goods, is projected to cause over a billion dollars in damages annually over the next decade. Treatment to prevent wood borer introductions treatment is worthwhile when the cumulative damages of widening infestations are considered, report scientists.

Science of school lunch: Pictures tell story about lunch policies, healthy consumption Posted: 23 May 2014 04:23 PM PDT Since Fall 2012, USDA regulations require students across the country to take a fruit or vegetable with their lunch, a good intention that might easily go to the garbage. To help assess what's really happening, researchers have developed state-of-the-art digital imaging to measure healthy food consumption.

Untangling whole genomes of individual species from a microbial mix Posted: 23 May 2014 04:23 PM PDT A new approach to studying microbes in the wild will allow scientists to sequence the genomes of individual species from complex mixtures. It marks a big advance for understanding the enormous diversity of microbial communities —- including the human microbiome.

Babbling brooks adding to climate change? Posted: 23 May 2014 04:23 PM PDT Studying stream bubbles isn't exactly a walk in the park. What, with the mud and ticks, the long days hiking and swimming through mucky streams, the sun exposure and scratching brush. But in the end, it may prove to be insightful. The bubbles coming from freshwater sources, new research suggests, may be a key and currently unaccounted for source of methane, the second-largest greenhouse gas contributor to human-driven global climate change.

New drug for non-Hodgkin lymphoma, chronic lymphocytic leukemia passes early test Posted: 23 May 2014 11:54 AM PDT A new chemotherapy drug being investigated for its potency against two types of cancer was found by scientists to be effective in about one-third of the 58 patients who participated in a phase I study. The drug, alisertib or MLN8237, inhibits the enzyme aurora A kinase, which is known to be very active during cell division. The present study looks at the safety, tolerability, and preliminary success of alisertib in treating non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL).

Personal judgments swayed by group opinion, but only for three days Posted: 23 May 2014 11:54 AM PDT We all want to feel like we're free-thinking individuals, but there's nothing like the power of social pressure to sway an opinion. New research suggests that people do change their own personal judgments so that they fall in line with the group norm, but the change only seems to last about three days.

Tiny muscles help bats fine-tune flight, stiffen wing skin Posted: 23 May 2014 11:53 AM PDT Bats appear to use a network of hair-thin muscles in their wing skin to control the stiffness and shape of their wings as they fly, according to a new study. The finding provides new insight about the aerodynamic fine-tuning of membrane wings, both natural and human-made.

Straw from oilseed as a new source of biofuels Posted: 23 May 2014 11:53 AM PDT Straw from crops such as wheat, barley, oats and oilseed rape is seen as a potential source of biomass for second generation biofuel production. Currently the UK produces around 12 million tonnes of straw. Although much is used for animal bedding, mushroom compost and energy generation, there still exists a vast surplus. Preliminary lab findings are pointing at ways that the process of turning straw from oilseed rape into biofuel could be made more efficient, as well as how the straw itself could be improved.

Breakthrough method for making Janus or patchy capsules Posted: 23 May 2014 11:53 AM PDT An easy method for making small hollow capsules with two or more patches with different chemical or physical properties has been found. These capsules, called Janus or patchy capsules, have potential applications in fields as varied as medicine and the food industry.

Measuring fine dust concentration via smartphone Posted: 23 May 2014 11:52 AM PDT Big cities in the smog: Photos from Beijing and, more recently, Paris clearly illustrate the extent of fine dust pollution. But what about our direct environment? What is the pollution concentration near our favorite jogging route? Scientists are developing a sensor that can be connected easily to smartphones. In the future, users are to take part in drawing up a pollution map via participatory sensing. The precision of the map will be the higher, the more people will take part.

How Alzheimer's blood test could be first step in developing treatments to halt or slow disease Posted: 23 May 2014 11:52 AM PDT A blood test has the potential to predict Alzheimer's disease before patients start showing symptoms, researchers have reported. Now they expand upon this groundbreaking research and discuss why it could be the key to curing this devastating illness. "This discovery is a potentially enormous breakthrough in the fight against Alzheimer's," said an expert. "If research aimed at a cure for Alzheimer's is to move forward, it is crucial that Alzheimer's clinical trials find a way to recruit patients who are still asymptomatic, since they are the ones most likely to respond to treatment."

Active genes in neurons profiled based on connections Posted: 23 May 2014 11:51 AM PDT When it comes to the brain, wiring isn't everything. Although neurobiologists often talk in electrical metaphors, the reality is that the brain is not nearly as simple as a series of wires and circuits. Unlike their copper counterparts, neurons can behave differently depending on the situation.

New glasses may increase risk of falls in older adults, suggests review Posted: 23 May 2014 11:51 AM PDT Blurred vision contributes to the risk of falling in older adults -— but getting new glasses with a big change in vision prescription may increase the risk rather than decreasing it, according to a new article. Unaccustomed magnification may cause objects to appear closer or farther than they really are, thus affecting the reflexes linking the vestibular (balance) system with eye movements. For older patients who aren't used to bifocals and "progressive" lenses, switching to these types of lenses may cause distortion in peripheral vision.

Electricity use slashed with efficiency controls for heating, cooling Posted: 23 May 2014 11:51 AM PDT Commercial buildings could cut their heating and cooling electricity use by an average of 57 percent with advanced energy-efficiency controls, according to a year-long trial of the controls at malls, grocery stores and other buildings across the country.

New phase in iron-based superconductors discovered Posted: 23 May 2014 06:43 AM PDT A previously unknown phase in a class of superconductors called iron arsenides has been discovered by scientists. This sheds light on a debate over the interactions between atoms and electrons that are responsible for their unusual superconductivity. "This new magnetic phase, which has never been observed before, could have significant implications for our understanding of unconventional superconductivity," said Ray Osborn, a physicist and coauthor on the paper.

Disaster Planning: Risk assessment vital to development of mitigation plans Posted: 23 May 2014 06:42 AM PDT Wildfires and flooding affect many more people in the USA than earthquakes and landslide and yet the dread, the perceived risk, of the latter two is much greater than for those hazards that are more frequent and cause greater loss of life. Research suggests that a new paradigm for risk assessment is needed.

10 'golden rules' of strategic flood management revealed by water scientists Posted: 23 May 2014 05:26 AM PDT With many families across the UK still dealing with the consequences of last winter's flooding, water scientists have recently released 10 'golden rules' for strategic flood management. While the authors acknowledge the 'remarkable progress in cultivating the concepts of flood risk management' that has taken place over the last few decades, they also recognize that 'the challenge now is to turn the now commonly accepted concepts of managing risks and promoting opportunities into common flood-management practice'.

Protective milk shot: How mother's milk protects piglets from parasite infections Posted: 23 May 2014 05:26 AM PDT Antibodies against C. suis are transferred via the sow's very first milk to the piglets immediately after birth. This was discovered by a veterinarian and parasitologist in 2013. These findings prompted other researchers to look for a way to increase the level of these antibodies in sows. The ultimate goal was to provide the piglets with as much antibodies as possible via their mother's milk during the first few days of life.

DNA testing to help save corals Posted: 23 May 2014 05:26 AM PDT To avert coral demise, experts report the establishment of DNA markers that might be applicable to all species of the Acropora reef-building coral, giving accurate identification to individual corals. The technique, similar to DNA profiling in humans, enables scientists to study genetic diversity and connectivity among the Acropora coral populations, thus finding clues to help with the conservation of coral reef ecosystems in waters around the world.
