Adolescents who are bullied about their weight or body shape may be more likely to use alcohol or marijuana than those who are not bullied, according to new research published by the American Psychological Association.
The link between appearance-related teasing and substance use was strongest among overweight girls, raising special concerns about this group.
Quantum entanglement is perhaps one of the most intriguing phenomena known to physics. It describes how the fates of multiple particles can become entwined, even when separated by vast distances. Importantly, the probability distributions needed to define the quantum states of these particles deviate from the bell-shaped, or 'Gaussian' curves which underly many natural processes. Non-Gaussian curves don't apply to quantum systems alone, however. They can also be composed of mixtures of regular Gaussian curves, producing difficulties for physicists studying quantum entanglement.
Philadelphia, February 25, 2020 - In pregnant women, obesity, diabetes, hypertension, depression and anxiety can increase the chances of learning delays, behavior problems and mental health issues in their children's early years.
New research led by scientists from the University of Bristol has revealed new insights into how the microscopic algae that thrives along the edge of the Greenland Ice Sheet causes widespread darkening.
This darkening is critically important as darker ice absorbs more sunlight energy and melts faster, accelerating the overall melting of the ice, which is the single largest contributor to global sea level rises.
Superatom is a name given to a cluster of atoms that seem to exhibit properties similar to elemental atoms. Scientists have shown particular interest in superatomic structures, since they can be linked with atoms to produce molecules, and potentially be used to substitute certain elements in many applications.
A remarkable new treasure has been found by scientists from the University of Portsmouth - the first fossil plant gum on record. The beautiful, amber-like material has been discovered in 110 million year old fossilised leaves.
University of Portsmouth PhD student Emily Roberts, made the discovery while examining fossilised leaves of the Welwitschiophyllum plant, found in the Crato Formation in Brazil. Emily noticed thin amber-coloured bands locked inside some of the fossilised leaves she was studying.
A powerful new approach to securing web browsers, using a tool called WebAssembly, is getting its first real-world application in the Firefox browser. Developed by a team of researchers from The University of Texas at Austin, the University of California San Diego, Stanford University and Mozilla, the approach shifts some of the browser code into "secure sandboxes" that prevent malicious code from taking over the user's computer.
Researchers at Stevens Institute of Technology have created a 3D imaging system that uses light's quantum properties to create images 40,000 times crisper than current technologies, paving the way for never-before seen LIDAR sensing and detection in self-driving cars, satellite mapping systems, deep-space communications and medical imaging of the human retina.
CHICAGO -- A study in the March issue of The Journal of the American Dental Association from the Centers for Disease Control and Prevention found that antibiotics and opioids are frequently prescribed during emergency department visits for dental conditions, further emphasizing the need for continued efforts to combat both opioid abuse and overuse of antibiotics.
Do a Google search for dark-field images, and you'll discover a beautifully detailed world of microscopic organisms set in bright contrast to their midnight-black backdrops. Dark-field microscopy can reveal intricate details of translucent cells and aquatic organisms, as well as faceted diamonds and other precious stones that would otherwise appear very faint or even invisible under a typical bright-field microscope.
CLEMSON, South Carolina -- In the quest to develop more effective treatments for parasitic diseases like African sleeping sickness, Chagas disease and Leishmaniasis, scientists look for weaknesses in the organisms' molecular machinery. These weaknesses can then be targeted with drug therapies designed to kill the parasites.
While they've made significant strides in recent years, scientists are still trying to unravel how the parasites' complex molecular systems work.
COLUMBUS, Ohio - Researchers have known that kids who are at high risk of being mistreated at home - who live in poverty or have parents who use drugs or have mental health problems - are more likely to start smoking. Because abused and neglected children are often unsupervised, these teens have easy access to cigarettes and other substances that they use to deal with anxiety and other trauma-related symptoms.
For decades, researchers have suggested a link between oral health and inflammatory diseases affecting the entire body -- in particular, heart attacks and strokes. Inflammation is intimately involved in the pathogenesis of atherosclerosis and is accurately measured by high sensitivity C-reactive protein (hs-CRP), a sensitive marker for future risks of heart attacks and strokes.
BEER-SHEVA, ISRAEL...February 24, 2020 - While no one at work wants to be kept waiting, according to a new study by researchers from Ben-Gurion University of the Negev (BGU) and the University of British Columbia (UBC), reactions to waiting can be managed to reduce aggression that may result from the wait.
DALLAS - Feb. 20, 2020 - Switching what the powerhouses of heart cells consume for energy could help the heart regenerate when cells die, a new study led by UT Southwestern researchers suggests. The finding, published in the Feb. 20, 2020, Nature Metabolism, could open whole new avenues for treating a variety of conditions in which heart muscle becomes damaged, including heart failure caused by viruses, toxins, high blood pressure, or heart attacks.
