Many wildlife-vehicle collisions preventable

Mié, 06/20/2018 - 22:00
A new study from the University of Waterloo has found that Ontario could save millions by implementing simple measures to help prevent vehicle accidents involving wildlife.

New study debunks Dale Carnegie advice to 'put yourself in their shoes'

Mié, 06/20/2018 - 22:00
The researchers debunk the theories canonized in Dale Carnegie's How to Win Friends and Influence People that assuming you understand someone else's thoughts, feelings, attitude, or mental state is a correct approach to interpersonal insight.

Novel therapy makes oxidative stress deadly to cancer

Mié, 06/20/2018 - 22:00
Oxidative stress can help tumors thrive, but one way novel cancer treatments work is by pushing levels to the point where it instead helps them die, scientists report.

Envisioning a future where all the trees in Europe disappear

Mié, 06/20/2018 - 22:00
Global climate change is already affecting the planet, as demonstrated by the shrinking polar ice cap, melting glaciers and cities in the grips of longer, more intense heat waves. Now a team of researchers has conducted a radical thought experiment on how extreme land use changes could influence future climate.

Old star clusters could have been the birthplace of supermassive stars

Mié, 06/20/2018 - 22:00
A team of international astrophysicists may have found a solution to a problem that has perplexed scientists for more than 50 years: why are the stars in globular clusters made of material different to other stars found in the Milky Way?

Exposure to fracking chemicals and wastewater spurs fat cell development

Mié, 06/20/2018 - 22:00
Exposure to fracking chemicals and wastewater promotes fat cell development, or adipogenesis, in laboratory cell models, a Duke-led study finds. Researchers observed increases in the size and number of fat cells after exposing the models to a mixture of 23 common fracking chemicals or to wastewater or surface-water samples containing them, even at diluted concentrations. Adipogenesis occurred through PPARy-dependent and independent mechanisms. More research is needed to assess potential health impacts outside the laboratory.

Research team reverse way potassium channels work from bacteria to human

Mar, 06/19/2018 - 22:00
Research develops a better understanding of and exerts an unparalleled control of protein molecules.

Super-resolution imaging reveals mechanism of GLUT1 clustering

Mar, 06/19/2018 - 22:00
Prof. WANG Hongda of the Changchun Institute of Applied Chemistry and Prof. XIONG Wenyong from the Kunming Institute of Botany, together with their team members, first investigated the distribution and assembly of GLUT1 at a nanometer resolution by direct stochastic optical reconstruction microscopy.

Marine reserves are vital -- but under pressure

Mar, 06/19/2018 - 22:00
A massive study of nearly 1800 tropical coral reefs around the world has found that marine reserves near heavily populated areas struggle to do their job -- but are a vast improvement over having no protection at all.

IASLC issues statement paper on liquid biopsy for lung cancer

Mar, 06/19/2018 - 22:00
The lungs can be a difficult organ to biopsy with a needle, so identifying lung cancer through a blood-based biopsy has lung cancer experts and patients optimistic. Knowing how and when to use a liquid biopsy is critically important and led global experts at the International Association for the Study of Lung Cancer (IASLC) to issue 'The IASLC Statement Paper: Liquid Biopsy for Advanced Non-Small Cell Lung Cancer (NSCLC),' available in the Journal of Thoracic Oncology.

Tumor suppressor protein plays key role in suppressing infections

Mar, 06/19/2018 - 22:00
Researchers have found that a previously uncharacterized tumor-suppressor protein plays an important role in the functioning of the immune system. The study, which will be published in the June 22 issue of the Journal of Biological Chemistry, unites studies of immunology and cancer biology.

Buildings as power stations -- data shows they work: They generate more energy than they consume

Mar, 06/19/2018 - 22:00
The UK's first energy-positive classroom, designed with research expertise from Swansea University, generated more than one and a half times the energy it consumed, according to data from its first year of operation, the team has revealed.The findings were announced as the researchers launched the next phase of their research, gathering data and evidence on an office building, constructed using similar methods.

No evidence that vitamin D protects against high blood pressure in pregnancy

Mar, 06/19/2018 - 22:00
There is no strong evidence that vitamin D protects against pregnancy-induced high blood pressure (hypertension) or pre-eclampsia, conclude researchers in The BMJ today.

When cozying up with would-be predators, cleaner shrimp follow a dependable script

Mar, 06/19/2018 - 22:00
It's a mystery how cleaner shrimp partner with would-be fish predators -- sometimes even climbing in their mouths -- without getting eaten. A new study reveals how the shrimp convinces fish not to eat them, and the fish conveys that it's a friend and not a foe.

Boring barnacles prefer the shallow life on coral reefs

Mar, 06/19/2018 - 22:00
Scientists at Rice University, the University of the Virgin Islands and the National Oceanic and Atmospheric Administration combine efforts to quantify how barnacles infest stony coral over a variety of conditions and reduce calcium carbonate on reefs. Coral reefs harbor diverse marine life and help prevent coastal erosion.

Rhesus macaque model offers route to study Zika brain pathology

Mar, 06/19/2018 - 22:00
Rhesus macaque monkeys infected in utero with Zika virus develop similar brain pathology to human infants, according to a report by researchers at the California National Primate Research Center and School of Veterinary Medicine at UC Davis. The findings may open up new ways to study the infection in an animal model.

GPM satellite probes soaking storms in Southern Texas and the Gulf

Mar, 06/19/2018 - 22:00
Southern Texas and the western Gulf of Mexico is getting a soaking because of a low pressure system. The Global Precipitation Measurement mission or GPM core satellite passed over the western Gulf of Mexico and measured the rainfall from the system.

DNA barcodes that reliably work: A game-changer for biomedical research

Mar, 06/19/2018 - 22:00
Researchers have developed a new method for correcting the errors that creep into DNA barcodes -- labels used in a wide range of biological experiments -- yielding far more accurate results and paving the way for more ambitious medical research in the future.

Martian dust storm grows global: Curiosity captures photos of thickening haze

Mar, 06/19/2018 - 22:00
A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA's Opportunity rover to suspend science operations. But across the planet, NASA's Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust. The Martian dust storm has grown in size and is now officially a 'planet-encircling' (or 'global') dust event.

Researchers identify method to diagnose cancer in patients with early onset diabetes

Mar, 06/19/2018 - 22:00
Patients diagnosed with pancreatic cancer can develop elevated blood sugar levels up to three years before their cancer diagnosis, according to the results of a study by Mayo Clinic researchers published the journal Gastroenterology.
