Researchers can now build an inexpensive and flexible micro-raman system
Raman spectroscopy provides detailed chemical information, and when combined with a microscope, it can non-destructively analyze biological samples. While commercial research-grade Raman microscopes have been available for some time, they have tended to be both inflexible and very expensive. In a paper in the current issue of Biomedical Spectroscopy and Imaging, researchers from Germany and Serbia describe an inexpensive, versatile micro-Raman system that can be assembled from readily available components at a fraction of the cost of a commercial tool.

Largest crowdsource astronomy network helps confirm discovery of 'Tatooine' planet
Lehigh University astronomer assistant professor of physics Joshua Pepper is using crowdsourcing to gather observations worldwide. His network, known as the 'KELT Follow-Up Network,' is made up of nearly 40 members in 10 countries across four continents. The group -- the largest, most coordinated network of its kind -- contributed key observations to confirm the existence of the recently-identified planet, Kepler-1647 b, announced today at a meeting of the American Astronomical Society.

Pituitary tissue grown from human stem cells releases hormones in rats
Researchers have successfully used human stem cells to generate functional pituitary tissue that secretes hormones important for the body's stress response as well as for its growth and reproductive functions. When transplanted into rats with hypopituitarism -- a disease linked to dwarfism and premature aging in humans -- the lab-grown pituitary cells promoted normal hormone release. The study, which lays the foundation for future preclinical work, appears June 14 in Stem Cell Reports.

Nearly 10 million adults found to be severely nearsighted in the United States
About 9.6 million US adults are severely nearsighted, a new study shows. Of those with high myopia, nearly 820,000 have a degenerative form. More than 41,000 suffer a rare complication called myopic choroidal neovascularization that can cause permanent vision loss. It's twice as prevalent in women than in men. These findings are being published by Ophthalmology, journal of the American Academy of Ophthalmology. The authors are from the Academy, UC Davis, NIH and Genentech.

Adolescent sleep duration is associated with daytime mood
A new study of adolescents suggests that obtaining an insufficient amount of sleep increases variability in sadness, anger, energy and feelings of sleepiness. The study also showed that nightly fluctuations in sleep in healthy adolescents predict worse mood the next day, and worse mood any given day largely predicts unusually bad sleep the next night.

Scientists learn more about how star-shaped brain cells help us learn
A molecule that enables strong communication between our brain and muscles appears to also aid essential communication between our neurons, scientists report.

How a cold gets into cells
Viruses smuggle their genetic material into our cells. How this actually works is currently being investigated at TU Wien using a new combination of analysis methods.

Exercise may have therapeutic potential for expediting muscle repair in older populations
Here's another reason why you should hit the gym regularly as you grow older: A new report appearing online in The FASEB Journal shows that regular exercise plays a critical role in helping muscles repair themselves as quickly as possible after injury. After only eight weeks of exercise, old mice experienced faster muscle repair and regained more muscle mass than those of the same age that had not exercised.

Radioactive cesium fallout on Tokyo from Fukushima concentrated in glass microparticles
New research shows that most of the radioactive fallout which landed on downtown Tokyo a few days after the Fukushima accident was concentrated and deposited in non-soluble glass microparticles, as a type of 'glassy soot.' These results are announced at the Goldschmidt geochemistry conference in Yokohama, Japan.

Warning from the past: Future global warming could be even warmer
Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past global warming and the carbon cycle on Earth 56 million years ago researchers from the Niels Bohr Institute et al. have used computer modelling to estimate the potential perspective for future global warming, which could be even warmer than previously thought.

NHS England needs to stop stalling and make HIV preventing treatment available
An effective treatment that can prevent HIV infection and reduce the human and financial costs of the preventable condition is taking too long to be commissioned and made available on the NHS, warns Deborah Gold, chief executive of the National Aids Trust, in an article published by The BMJtoday.

Study: Exercise can help adults better cope with ADHD symptoms

Scientists discover oldest plant root stem cells
Scientists at Oxford University have discovered the oldest known population of plant root stem cells in a 320 million-year-old fossil. The cells, which gave rise to the roots of an ancient plant, were found in a fossilized root tip held in the Oxford University Herbaria.

Running releases protein associated with improved memory in mice
The reason why treadmill training can boost memory recall remains an active area of investigation. A couple of proteins have been shown to fuel exercise-induced neuron growth, but a June 23 study in Cell Metabolism presents a new candidate, cathepsin B -- one that can be directly traced from the muscles to the brain in mice. Also, after a run, protein levels increased in blood in mice, monkeys, and humans.

New electric mesh device gives the heart an electromechanical hug
A research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Seoul National University has developed a new electric mesh device that can be wrapped around the heart to deliver electrical impulses and thereby improve cardiac function in experimental models of heart failure, a major public health concern and leading cause of mortality and disability.

Hops could help reduce breast cancer risk
Hops, the flower cones used in beer-making, are also found in dietary supplements designed to help treat post-menopausal symptoms and other conditions. Scientists are now investigating whether an extract from the plant could also help fend off breast cancer. In the ACS journal Chemical Research in Toxicology, one team reports new lab tests on breast cells that support this possibility.

Analogue quantum computation has been universally digitized using superconducting circuits
The QUTIS research group (www.qutisgroup.com) of the University of the Basque Country (UPV/EHU) and Google's quantum computation team have collaborated on a pioneering experiment that universally digitizes analogue quantum computation on a superconducting chip.

A safety monitoring method called On-Site Visualization has been implemented in metro system construction sites in Jakarta, Indonesia as part of a Japan International Cooperation Agency project.

Pneumococcal vaccine watches bacteria, strikes only when needed
Conventional vaccines indiscriminately destroy bacteria and other disease-causing agents. The approach works, but there is growing concern that it creates opportunity other pathogens to harm the body -- similar to antibiotic resistance resulting in new and more potent pathogens. A new, protein-based pneumococcal vaccine takes a different approach. It allows pneumonia-causing bacteria to colonize in the body and -- like a nightclub bouncer -- swings into action only if the bacteria becomes harmful.

Falls in months before surgery are common in adults of all ages
Falling up to six months before an elective surgery was common and caused injuries among adults of all ages, according to researchers at Washington University School of Medicine in St. Louis. Surprisingly, the frequency of falls among middle-aged patients was higher than those who were elderly. The study suggests that falling may be an important indicator of baseline health.

Understanding how chemical changes in the brain affect Alzheimer's disease
A new study from Western University is helping to explain why the long-term use of common anticholinergic drugs used to treat conditions like allergies and overactive bladder lead to an increased risk of developing dementia later in life. The study used mouse models to show that long-term suppression of the neurotransmitter acetylcholine -- a target for anticholinergic drugs -- results in dementia-like changes in the brain.

E-consults increase access to specialty care, reduce need for face-to-face appointments
Research presented today at AcademyHealth's Annual Research Meeting found that use by physicians of e-consults increases access to specialists' care for patients who often have the hardest time getting a specialist, including the uninsured, underinsured and those living in rural areas. E-consults streamline communication between primary care providers and specialists. Studies highlight how e-consults can decrease wait times, improve clinical care and reduce the need for face-to-face appointments.

Childhood binge eating: Families, feeding, and feelings
In order to put childhood binge eating into context, a new systematic review from the University of Illinois identifies two potential risk factors for binge eating in children under the age of 12. With family being the most proximal and influential setting affecting behaviors and attitudes in children, the study reports that parental non-involvement or emotional unresponsiveness and weight-related teasing in the family are behaviors consistently associated with childhood binge eating.

Small brain -- astounding performance
The elephantnose fish explores objects in its surroundings by using its eyes or its electrical sense -- sometimes both together. Zoologists at the University of Bonn and a colleague from Oxford have now found out how complex the processing of these sensory impressions is. With its tiny brain, the fish achieves performance comparable to that of humans or mammals. The advance results have been published online in PNAS.

Pea plants demonstrate ability to 'gamble' -- a first in plants
An international team of scientists from Oxford University, UK, and Tel-Hai College, Israel, has shown that pea plants can demonstrate sensitivity to risk -- namely, that they can make adaptive choices that take into account environmental variance, an ability previously unknown outside the animal kingdom. In the study, published in the journal Current Biology, pea plants were grown with their roots split between two pots, thus facing the decision of which pot to prioritize.
