SAN DIEGO, March 13, 2016 -- Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.

The researchers present their work today at the 251st National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features more than 12,500 presentations on a wide range of science topics.

SAN DIEGO, March 13, 2016 -- Hops, those little cone-shaped buds that give beer its bitter flavor, pack a surprisingly healthful punch. They are widely studied for their ability to halt bacterial growth and disease. Now, researchers report that they are close to synthesizing the healthful hops compounds in the lab. This advance could one day help scientists create medicines from these compounds without having to extract them from plants.

SAN DIEGO, March 13, 2016 --Women can choose from a wide selection of birth control methods, including numerous oral contraceptives, but there's never been an analogous pill for men. That's not for lack of trying: For many years, scientists have attempted to formulate a male pill. Finally, a group of researchers has taken a step toward that goal by tweaking some experimental compounds that show promise.

EUGENE, Ore. -- (March 8, 2016) -- If you have trouble sleeping, the neurons in your brain may be firing like those in roundworms randomly seeking food in the absence of clues, says University of Oregon biologist Shawn R. Lockery.

That connection is proposed in a theoretical neuroscience paper co-authored by 12 researchers at 10 institutions that is in the journal eLife. The research -- 14 years in the making -- was led by Lockery and supported by the National Institutes of Health.

As humans sleep, neurons fire randomly in between brief, alternating states of wakefulness and sleep. Such fragmentation is heightened in sleep disorders.

Crowds formed from tiny particles disperse as their environment becomes more disordered, according to scientists from UCL, Bilkent University and Université Pierre et Marie Curie.

The new mechanism is counterintuitive and might help describe crowd behaviour in natural, real-world systems where many factors impact on individuals' responses to either gather or disperse.

"Bacterial colonies, schools of fish, flocking birds, swarming insects and pedestrian flow all show collective and dynamic behaviours which are sensitive to changes in the surrounding environment and their dispersal or gathering can be sometimes the difference between life and death," said lead researcher, Dr Giorgio Volpe, UCL Chemistry.

By now the entire world has heard that famed Russian tennis champion Maria Sharapova has tested positive for a banned substance. According to a March 9 Reuters article, she has been suspended, lost major sponsors and there is a possibility that she will miss the upcoming Olympics. The substance she was taking is Meldonium or Mildronate.

This is a heart medication that is most commonly used in Eastern Europe. This medication has been banned effective only this past January. Meldonium works by regulating the energy metabolism pathways. It has been used for treatment of heart failure, arrhythmia, heart attacks and diabetes. It has not been approved for use in the United States.

If the price of oil decreases, carbon dioxide emissions increase. This is what two Spanish scientists claim after comparing the relationship between air pollution and economic development by using the real oil prices in Spain between 1874 and 2011 as an indicator. The scientists suggest a need to design new energy taxes.

In the 1970s, the first environmental movements warned that air pollution was the result of our production and consumption patterns. At that point in time, economists argued that an improvement in per capita income would reduce the level of environmental degradation -- a relationship called the Environmental Kuznets Curve (with an inverted 'U' shape). Later studies would go on to show that they were right.

Estoril, Portugal: Beta-blockers could be used to reduce the risk of chronic obstructive pulmonary disease (COPD) exacerbations, according to new findings.

Beta blockers are primarily used to treat stress or heart problems, such as high blood pressure and angina, but these new findings suggest they could have a potential benefit for patients with COPD.

In a large-scale study involving more than 6,000 fifth graders, an innovative science curriculum was found to have a positive impact on science learning for students with different levels of English proficiency.

The study, led by NYU Steinhardt School of Culture, Education, and Human Development and published in the American Educational Research Journal, evaluated the effects of Promoting Science Among English Language Learners (P-SELL), a fifth-grade science curricular and professional development intervention designed with English language learners (ELLs) in mind.

Recently, researchers compared the effects of tai chi to leg strengthening exercises (a physical therapy called "lower extremity training," or LET) in reducing falls. Falls are a leading cause of serious injuries in older adults and can lead to hospitalization, nursing home admission, and even death. Arthritis, heart disease, muscle weakness, vision and balance problems, dementia, and other age-related health problems can increase an older adult's risk for experiencing a fall. The study is published in the Journal of the American Geriatrics Society.
