ACP brings prescription to improve American health care to Congress

Lun, 05/22/2017 - 22:00
The American College of Physicians today released a set of recommendations aimed at providing a forward-thinking agenda for health care reform, 'A Prescription for a Forward-Looking Agenda to Improve American Health Care.' The paper articulates ACP's view that now is the time to move away from the debate over repealing and replacing the ACA, and instead, urges Congress and the administration to join with ACP and others to create and implement a forward-looking agenda to improve American health care.

Rising incidence of tick-borne Powassan virus infection in North America

Lun, 05/22/2017 - 22:00
Cases of human infection with Powassan virus (POWV), which can cause fatal neuroinvasive disease and long-term neurological effects, appear to be increasing in the United States. POWV is transmitted by Ixodes tick species found in North America.

Depression risk following natural disaster can be predicted via pupil dilation

Lun, 05/22/2017 - 22:00
Pupil dilation could identify which individuals are at greatest risk for depression following disaster-related stress, and help lead to targeted interventions, according to new research from Binghamton University, State University of New York.

Common artificial sweetener likely a safe, effective birth control and pesticide

Lun, 05/22/2017 - 22:00
Erythritol, a non-nutritive sweetener found in products like Truvia, has proven effective in killing fly larvae and slowing down their egg production, making it a good candidate for human and pet-safe pesticide use.

CAST project places new limitations on dark matter

Lun, 05/22/2017 - 22:00
CERN research results deliver no evidence for the existence of solar axions.

How to obtain highly crystalline organic-inorganic perovskite films for solar cells

Lun, 05/22/2017 - 22:00
Members of the Laboratory of New Materials for Solar Energetics, working at the Faculty of Material Sciences, in cooperation with their colleagues from the Faculty of Chemistry of the Lomonosov Moscow State University have elaborated a new method. It allows to obtain highly crystalline organic-inorganic perovskite films for solar cells.

Should you pee on a jellyfish sting? (video)

Lun, 05/22/2017 - 22:00
We all know the evils that come from a run-in with a jellyfish's tentacles. But thankfully, we can resort to peeing on a sting to make the pain go away -- or can we? Filmed at San Francisco's Aquarium of the Bay, the latest Reactions episode explains the fearsome chemistry of jellyfish stings, and debunks this age-old beach myth: https://youtu.be/KDj2t4-bn1g.

Making biological drugs with spider silk protein

Lun, 05/22/2017 - 22:00
Researchers at Karolinska Institutet in Sweden have managed to synthesise lung surfactant, a drug used in the care of preterm babies, by mimicking the production of spider silk. Animal studies reveal it to be just as effective as the biological drugs currently in clinical use. The study is published in Nature Communications.

Tracking cancer's signaling pathways

Lun, 05/22/2017 - 22:00
Malignant melanoma is one of the most common and dangerous types of cancer. Researchers at Friedrich-Alexander Universität Erlangen-Nürnberg investigated how and why brown pigmented moles turn into malignant melanoma using innovative robot technology. The insights gained can simplify methods of diagnosis in the future; furthermore, they suggest that certain cosmetic products and creams should be avoided.

Probing problems with bariatric surgery: Reoperations, variation are common

Lun, 05/22/2017 - 22:00
Every year, nearly 200,000 Americans turn to surgeons for help with their obesity, seeking bariatric surgery to lose weight and prevent life-threatening health problems. But after more than two decades of steadily increasing numbers of operations, American bariatric surgery centers still vary greatly in the quality of care they provide.

Tracking down the scent of recycled plastic

Lun, 05/22/2017 - 22:00
Recycling plastic has an important role in sustainable manufacturing. However, there are still barriers to using recycled plastic not only because of its material and processing properties but also because of its smell. A young researcher at Friedrich-Alexander Universität Erlangen-Nürnberg has now studied what causes recycled plastic to smell.

Optimization of hemp-ground tire rubber/high density polyethylene composites

Lun, 05/22/2017 - 22:00
Recent interest in lignocellulosic fibers was devoted to improve the mechanical properties of polymers. But one of their main limitation is the poor compatibility and adhesion between these polar/hydrophilic fibers with most commercial resins being non-polar and hydrophobic. This problem has been partially solved using physical and chemical surface treatments, and/or the addition of a coupling agent (phase compatibilization).

A CLOUD of possibilities: Finding new therapies by combining drugs

Lun, 05/22/2017 - 22:00
The CeMM Library of Unique Drugs (CLOUD) is the first condensed set of FDA-approved drugs representing all clinical compounds. Its potential was shown in a combinatorial high throughput screen at the CeMM chemical screening platform, published in Nature Chemical Biology: by testing all CLOUD compounds in combination with each other, a pair of hitherto unrelated drugs proved to be highly effective against multiple prostate cancer cell lines known for their resistance to therapy.

Mystery of butterfly research resolved

Lun, 05/22/2017 - 22:00
It has only been one year since the material scientists around Prof. Erdmann Spiecker from the Centre for Nanoanalysis and Electron Microscopy (CENEM) at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) were granted funding for one of the world's best X-ray microscopes and they could already help unravelling an open question in butterfly research with fascinating 3D analyses.

Rethinking exercise: Replace punishing workouts with movement that makes you happy

Lun, 05/22/2017 - 22:00
Many women start fitness programs to lose weight, and when they don't, they feel like failures and stop exercising

Stem cells may significantly improve tendon healing by regulating inflammation

Lun, 05/22/2017 - 22:00
New research published online in The FASEB Journal suggests that tendon stem may be able to significantly improve tendon healing by regulating inflammation, which contributes to scar-like tendon healing and chronic matrix degradation. This has implications for the treatment of acute tendon injuries and chronic tendon disease.

Increased lysyl oxidase may be a significant contributor to heart disease and cancer

Lun, 05/22/2017 - 22:00
It's known that people with high blood pressure have increased levels of the enzyme lysyl oxidase (LOX), but it has not been clear if LOX actually contributes to heart disease. Now, a new research report appearing online in The FASEB Journal helps answer this question by showing that LOX does negatively affect heart function in mice.

Solar cells more efficient thanks to new material standing on edge

Lun, 05/22/2017 - 22:00
Researchers from Lund University in Sweden and from Fudan University in China have successfully designed a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material's ability to self-organise by standing on edge.

Research decoding the first deep-sea mussel genome published in Nature

Lun, 05/22/2017 - 22:00
A joint research led by HKBU and HKUST has assembled the 1.64 gigabytes genome of a deep-sea mussel, which is roughly equivalent to 50 percent of the size of human genome. This is the first decoded genome among all deep-sea macrobenthic animals, revealing a complete set of DNA.

Three new mini thorn snails described from Georgia (USA), Belize and Panama

Lun, 05/22/2017 - 22:00
Computer tomographic scans are used in a pioneering initiative by Adrienne Jochum and her interdisciplinary team of scientists to describe snails too small to handle. In a paper published in the open access journal ZooKeys, the scans elucidated three new species of thorn snails - a group of tiny, fragile and colourless land snails (<2 mm) showing characteristic internal sculpture. Uncovered through molecular analysis, the new species are described from Georgia (USA), Belize and Panama.
