EVANSTON, Ill. -- If you combine two or three metals together, you will get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns.
But once in a while, under just the right conditions, you get something entirely new: a futuristic alloy called metallic glass. The amorphous material's atoms are arranged every which way, much like the atoms of the glass in a window. Its glassy nature makes it stronger and lighter than today's best steel, and it stands up better to corrosion and wear.
Scientists at Tokyo Institute of Technology (Tokyo Tech) used synthetic-aperture radar data from four different satellites, combined with statistical methods, to determine the structural deformation patterns of the largest bridge in Iran.
Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale which originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is expected to change when the atoms are set in motion but the connection between polarization and atomic motions has remained unknown.
Lugano-Geneva, 12 April 2018 - Further evidence that immunotherapy provides long-term survival benefit for patients with lung cancer was presented today at ELCC 2018 (European Lung Cancer Congress) in Geneva, Switzerland. (1)
Geologists have discovered that some magmas split into two separate liquids, one of which is very rich in iron. Their findings can help to discover new iron ore deposits for mining.
Iron ore is mined in about 50 countries, with Australia, Brazil and China as the largest producers. It is mostly used to produce the steel objects that are all around us - from paper clips to kitchen appliances and the supporting beams in skyscrapers.
A new study by geoscientists at the University of Liverpool has identified the temperature at which cooling magma cracks to form geometric columns such as those found at the Giant's Causeway in Northern Ireland and Devils Postpile in the USA.
Geometric columns occur in many types of volcanic rocks and form as the rock cools and contracts, resulting in a regular array of polygonal prisms or columns.
Columnar joints are amongst the most amazing geological features on Earth and in many areas, including the Giant's Causeway, they have inspired mythologies and legends.
TORONTO, April 11, 2018 - Higher cigarette prices would save millions of people from extreme poverty and poor health around the world, while also cutting health treatment costs for families across the globe, suggests a comprehensive study published today in The BMJ.
In a two-year community randomised trial involving more than 15,000 children in Tanzania, a long lasting insecticidal net treated with piperonyl butoxide (PBO LLIN) reduced the prevalence of malaria by 44% and 33% in the first and second year respectively, compared to a standard long lasting insecticidal net (LLIN) treated with pyrethroid only.
Bees could be at risk from climate change because more frequent droughts could cause plants to produce fewer flowers, new research shows.
Droughts are expected to become more common and more intense in many parts of the world, and researchers studied the impact on flowering plants using a field experiment.
They found that drought roughly halved the overall number of flowers. This means less food for bees and other pollinators, which visit flowers for the nectar and pollen that they provide.
Immunotherapies are treatments that stimulate a patient's immune cells to attack the tumor. They can be very effective in melanoma - a common and aggressive form of skin tumor - but still fail in the majority of the patients. To address this, researchers are trying to identify the factors that enable successful immunotherapy, as well as those that may limit it. The ultimate goal is to open new avenues for immunotherapies that are more broadly effective in melanoma, and potentially other cancer types.
APRIL 11, 2018, NEW YORK -- A Ludwig Cancer Research study has shown that an entirely new type of personalized cancer vaccine induces novel, potent and clinically effective immune responses in patients receiving a combination of standard therapies for recurrent, stage III and IV ovarian cancer.
ANN ARBOR--In an advance that could grime-proof phone screens, countertops, camera lenses and countless other everyday items, a materials science researcher at the University of Michigan has demonstrated a smooth, durable, clear coating that swiftly sheds water, oils, alcohols and, yes, peanut butter.
Science has yet to unravel a complete understanding of the brain and all its intricate workings. It's not for lack of effort.
Over many decades, multiple research studies have sought to understand the dizzying "talk," or interconnectivity, between thousands of microscopic entities in the brain, in particular, neurons. The goal: to one day arrive at a complete brain "mapping" -- a feat that could unlock tremendous therapeutic potential.
Smartphones are an integral part of most people's lives, allowing us to stay connected and in-the-know at all times. The downside of that convenience is that many of us are also addicted to the constant pings, chimes, vibrations and other alerts from our devices, unable to ignore new emails, texts and images. In a new study published in NeuroRegulation, San Francisco State University Professor of Health Education Erik Peper and Associate Professor of Health Education Richard Harvey argue that overuse of smart phones is just like any other type of substance abuse.
DALLAS, April 11, 2018 -- Smoke from wildfires may send people - particularly seniors - to hospital emergency rooms (ERs) with heart, stroke-related complaints, according to new research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Previous studies have shown that wildfire smoke exacerbates respiratory conditions but yielded inconsistent results for effects on the heart, brain or blood vessels.
