Very small steps make a big difference to researchers who want to create large wafers of two-dimensional material.
Atom-sized steps in a substrate provide the means for 2D crystals growing in a chemical vapor furnace to come together in perfect rank. Scientists have recently observed this phenomenon, and now a Rice University group has an idea why it works.
In a groundbreaking Cornell-led study illuminating the extensive scope of mass incarceration in the U.S., nearly 1 in 2 Americans have had a brother or sister, parent, spouse or child spend time in jail or prison - a far higher figure than previously estimated.
The study is the first to accurately measure the share of Americans - 45 percent - who have ever had an immediate family member jailed or imprisoned for one night or more. The researchers had assumed they would find half that rate.
CLEMSON, South Carolina - New research published today in Scientific Reports has devised a way to track tiny message-carriers in the brain that could prove useful in diagnosing and treating injuries, infections or diseases.
The study, from assistant professor David Feliciano's lab in Clemson's College of Science, uses a glowing mouse - appropriately dubbed the "TIGER mouse" - to trace the movement of information-rich particles found in bodily fluids throughout the body, called extracellular vesicles (EVs).
MINNEAPOLIS - People who are witnessed by a bed partner to have stopped breathing during sleep may have higher accumulations of an Alzheimer's disease biomarker called tau in an area of the brain that helps with memory, according to a preliminary study released today that will be presented at the American Academy of Neurology's 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.
Obstructive sleep apnea is a condition that involves frequent events of stopped breathing during sleep, although an apnea may also be a single event of paused breathing during sleep.
New University of Liverpool research, published in Pediatrics, highlights the negative influence that social media has on children's food intake.
Current research shows celebrity endorsement and television advertising of unhealthy foods increases children's intake of these foods. However, children are increasingly exposed to marketing through digital avenues, such as on social media, and the impact of marketing by YouTube video bloggers (vloggers) on these outcomes has, until now, not been known.
Scientists have revealed for the first time the natural weapon used by marigolds to protect tomato plants against destructive whiteflies.
Researchers from Newcastle University's School of Natural and Environmental Sciences, carried out a study to prove what gardeners around the world have known for generations - marigolds repel tomato whiteflies.
March 1, 2019--Critically ill patients are more likely to be successfully weaned from a mechanical ventilator, or breathing machine, if they have higher levels of wakefulness and both their right and left brains experience the same depth of sleep, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical C
Tracking the firings of individual neurons is like trying to discern who is saying what in a football stadium full of screaming fans. Until recently, neuroscientists have had to tediously track each neuron by hand.
Malaria, which claims hundreds of thousands of lives each year - mainly children and especially in Africa -, is one of the leading causes of death by an infectious agent, the Plasmodium falciparum parasite. In research on malaria, the genetic mutation that causes sickle cell anemia (also known as drepanocytosis), a chronic disease that is often fatal in children under five, caught the attention of the scientific community very early on because it also provides protection against malaria.
Prehistoric worms populated the sea bed 500 million years ago--evidence that life was active in an environment thought uninhabitable until now, research by the University of Saskatchewan (USask) shows.
The sea bed in the deep ocean during the Cambrian period was thought to have been inhospitable to animal life because it lacked enough oxygen to sustain it.
Researchers at University of California San Diego School of Medicine have identified a clear group of characteristics that predict heightened risk for experiencing increased anxiety or worsening of mood that interferes with daily activities when using a smoking cessation drug. Results are published in the February 27, 2019 online edition of the Journal of General Internal Medicine.
A modelling study published in The Lancet Oncology journal estimates that there are almost 400,000 new cases of childhood cancer annually, while current records count only around 200,000.
Soils all over the Earth's surface are rigorously tested and managed. But what about soils that are down in the murky depths? Although not traditional soils, underwater soils have value and function. Some scientists are working to get them the recognition and research they deserve.
One of these scientists is Mark Stolt from the University of Rhode Island. He and his team are working to sample and map underwater soils.
A new way to create proteins that can sneak through HIV's protective coating may be a step toward understanding the key components needed for developing a vaccine for the virus, according to researchers.
Using computational modeling, a team of researchers led by Penn State designed and created proteins that mimicked different surface features of HIV. After being immunized with the proteins, rabbits developed antibodies that were able to bind with the virus.
WEST LAFAYETTE, Ind. -- Quantum computers will process significantly more information at once compared to today's computers. But the building blocks that contain this information - quantum bits, or "qubits" - are way too sensitive to their surroundings to work well enough right now to build a practical quantum computer.
Long story short, qubits need a better immune system before they can grow up.
