Mangrove patches deserve greater recognition no matter the size

Jue, 01/17/2019 - 23:00
Governments must provide stronger protection for crucial small mangrove patches, is the call led by scientists at international conservation charity ZSL (Zoological Society of London), which hosts the IUCN SSC Mangrove Specialist Group, in a letter published in Science today.

Researchers examine how musicians communicate non-verbally during performance

Jue, 01/17/2019 - 23:00
A team of researchers from McMaster University has discovered a new technique to examine how musicians intuitively coordinate with one another during a performance, silently predicting how each will express the music.

Exposure to chemicals during pregnancy is not associated with an increase in blood pressure

Jue, 01/17/2019 - 23:00
New study analyses the health impact of exposure to 21 non-persistent chemicals among pregnant women.

Antibodies to a retina protein to be used as a kidney cancer marker

Jue, 01/17/2019 - 23:00
Sechenov University together with their German colleagues suggest a new highly sensitive, quick, and pain-free method for diagnosing kidney cancer. This method is based on measuring of the immune response to arrestin-1, a retina protein that is synthesized in the cancerous cells of kidneys.

Tinkering with public debt we doom innovation and growth

Jue, 01/17/2019 - 23:00
New research by Bocconi University's Mariano Max Croce and colleagues finds that public debt is bad for growth also because it hinders innovative firms' investment. 'By affecting their cost of capital, movements in government debt impact firms' investment and, critically, innovation decisions,' Professor Croce says. The net result is a GDP growth drop in four to five years, when the lack of innovation starts to affect the national economy.

How gut bacteria affect the treatment of Parkinson's disease

Jue, 01/17/2019 - 23:00
Patients with Parkinson's disease are treated with levodopa, which is converted into dopamine, a neurotransmitter in the brain. In a study published on Jan. 18, in the journal Nature Communications, scientists from the University of Groningen show that gut bacteria can metabolize levodopa into dopamine. As dopamine cannot cross the blood-brain barrier, this makes the medication less effective -- even in the presence of inhibitors that should prevent the conversion of levodopa.

Researchers find new ways to harness wasted methane

Jue, 01/17/2019 - 23:00
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) presented new ways to harness wasted methane.

Hand-knitted molecules

Jue, 01/17/2019 - 23:00
Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips -- in a sense as a 'hand-knitted' unique specimen. The properties of the molecules can be monitored in real time while they are being produced. The research results have just been published in Nature Communications.

New therapeutic avenue in the fight against chronic liver disease

Jue, 01/17/2019 - 23:00
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer.

Mediterranean freshwater fish species susceptible to climate change

Jue, 01/17/2019 - 23:00
Climate change will strongly affect many European freshwater fish species. This is particularly the case for species in the Mediterranean region, according to the latest findings of an international team of researchers from institutions including IGB, the University of Girona in Spain, the Norwegian Research Centre (NORCE) and the Czech Academy of Sciences.

Plant peptide helps roots to branch out in the right places

Jue, 01/17/2019 - 23:00
How do plants space out their roots? A Japanese research team has identified a peptide and its receptor that help lateral roots to grow with the right spacing. The findings were published on Dec. 20, 2018 in the online edition of Developmental Cell.

Untargeted metabolomics for atherosclerotic cardiovascular diseases

Jue, 01/17/2019 - 23:00
Cardiovascular Disease (CVD) is the leading cause of mortality and morbidity worldwide. Four out of five CVD deaths are due to myocardial infarction or stroke. Despite many initiatives that have been established for CVD prevention and risk management, and new therapies to treat existing CVD, patients continue to die from cardiac events.

Nerve growth factor: Early studies and recent clinical trials

Jue, 01/17/2019 - 23:00
NGF is the first discovered member of a family of neurotrophic factors, collectively indicated as neurotrophins, (which include brain-derived neurotrophic factor, neurotrophin-3 and neurotrophin 4/5). NGF was discovered for its action on the survival and differentiation of selected populations of peripheral neurons.

Musculoskeletal and rheumatic diseases induced by immune checkpoint inhibitors

Jue, 01/17/2019 - 23:00
Immune checkpoint inhibitors are a new promising class of antitumor drugs that have been associated with a number of immune-related Adverse Events (AEs), including musculoskeletal and rheumatic disease.

Fidarestat prevents high-fat diet-induced intestinal polyps in ApcMin/+ mice

Jue, 01/17/2019 - 23:00
Recent epidemiological and experimental studies have shown that obesity is a major risk factor for Colorectal Cancer (CRC). Regular intake of high fat-containing diet can promote obesity and metabolic syndrome by increasing the insulin resistance and inflammatory response which contribute to carcinogenesis.

Otoliths -- the fish's black box -- also keeps an eye on the metabolism

Jue, 01/17/2019 - 23:00
For the first time ever, an international research team has shown that fish otoliths record information on fish metabolism. Analyses of old and new otoliths can therefore provide new knowledge about how different species of fish adapt to new conditions, including climate change.

Long periods of undisturbed sleep during pregnancy may be associated with stillbirth

Jue, 01/17/2019 - 23:00
Sleeping more than nine hours per night during pregnancy may be associated with late stillbirth, a new Michigan Medicine-led international study suggests.

Enhanced NMR reveals chemical structures in a fraction of the time

Jue, 01/17/2019 - 23:00
MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.

Smart microrobots that can adapt to their surroundings

Jue, 01/17/2019 - 23:00
Scientists at EPFL and ETH Zurich have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.

New study shows physician-targeted marketing is associated with increase in opioid overdose deaths

Jue, 01/17/2019 - 23:00
New research from NYU School of Medicine and Boston Medical Center published online Jan. 18 in JAMA Network Open shows that increased marketing of opioid products to physicians -- from consulting fees to free meals -- is associated with higher opioid prescribing rates and elevated overdose deaths in the US.
