EVANSTON, Ill. --- Stereotypes often guide our perceptions of members of social groups. However, research has yet to document what stereotypes may exist for the fastest growing youth demographic in the U.S. -- biracial individuals.
Are biracial Black-White individuals perceived to be more similar to Black people or White people? And when people stereotype biracial Black-White individuals, do they stereotype them more like Black people or more like White people?
Scientists have developed a new method for detecting traces of primordial life in ancient rock formations using potassium.
The method relies on searching for high concentrations of potassium in ancient sedimentary rocks, rather than traditional methods that look for carbon, sulfur, or nitrogen--which can appear in ancient rocks through processes unrelated to ancient life.
A theoretical-experimental collaboration across two FLEET nodes has discovered new magnetic properties within 2D structures, with exciting potential for researchers in the emerging field of 'spintronics'.
Spintronic devices use a quantum property known as 'spin', in addition to the electronic charge of conventional electronics.
Spintronics thus promise ultra-high speed low-energy electronic devices with significantly enhanced functionality.
A layer of cells that look like normal stomach lining on top of sites of stomach cancer can make it difficult to spot after removal of a Helicobacter pylori infection. In a recent study, researchers from Hiroshima University have uncovered the origin of this layer of cells: it is produced by the cancer tissue itself.
The brain appears to implement a GPS system for spatial navigation; however, it is not yet fully understood how it works. In the journal Science Advances, researchers from Freiburg, Bochum and Beijing now suggest that rhythmic fluctuations in brain activity, so-called theta oscillations, may play a role in this process. These brainwaves might help remember the locations to which a person is navigating. This is the result of the researchers' study conducted with epilepsy patients who had electrodes implanted in the brain for the purpose of surgical planning.
Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before. They have now published their results in the journal Science.
DUBLIN, 2 July, 2019: A study led by researchers at RCSI's Department of Chemistry has the potential to help surgeons more accurately remove tumours and detect cancer in lymph nodes during surgery. The research, led by RCSI Professor of Chemistry Donal O'Shea, has been published in Chemical Science.
Scientists at McMaster University have identified new biomarkers for Irritable Bowel Syndrome (IBS) in urine, which could lead to better treatments and reduce the need for costly and invasive colonoscopy procedures currently used for diagnosis.
Little is known about the causes of IBS, a chronic and often debilitating gastrointestinal disorder which affects hundreds of thousands of Canadians in which diagnosis is complicated, patients experience a vast spectrum of symptoms and treatment options are limited.
Researchers at the University of Toronto have uncovered an immune mechanism by which host cells combat bacterial infection, and at the same time found that a protein crucial to that process can sense and respond to misfolded proteins in all mammalian cells.
The protein is called heme-regulated inhibitor or HRI, and the researchers showed that during bacterial infection it triggers and coordinates a chain reaction among other proteins that form a larger complex. That larger group or 'signalosome' amplifies inflammation and leads to an anti-bacterial response.
A diverse set of experiments supported by simulations were able to rationalize the effect of specific electrostatic forces exerted by the molecular building blocks on charge carriers. The study was published recently in Nature Communications.
It's the season for a cold, refreshing gin and tonic. We may question the health impact of one too many, but what is the environmental footprint of that classically delicious aperitif?
A tiny fibre-optic sensor has the potential to save lives in open heart surgery, and even during surgery on pre-term babies.
The new micro-medical device could surpass traditional methods used to monitor blood flow through the aorta during prolonged and often dangerous intensive care and surgical procedures - even in the tiniest of patients.
The continuous cardiac flow monitoring probe, under development at Flinders University, is a safe way to give a real-time measurement of blood flow.
The tumor microenvironment (TME) is a mix of fluids, immune cells and blood vessels which envelops the tumors. Interactions between tumor cells and the TME determine the progression and fate of tumors. Therefore, understanding the composition and functions of the TME is thus very important for keeping cancer in check. Although several genetic mutations can result in the incidence of cancer, not much is known about their effects on the TME. A research team led by Chiaki Takahashi at Kanazawa University has recently reported the role of one such cancer gene, RB, in this regard.
The transition to retirement changes the way people use their time and how actively they exercise. Evaluating a person's daily sedentary time using questionnaires is difficult. Therefore, the study measured changes in the sedentary time of aging workers with the help of a motion sensor attached to the wrist.
An international collaboration of chemists from Tomsk Polytechnic University, USA, Great Britain, Canada, Belgium, and France has developed a line of polyvalent iodine-based reagents for organic synthesis. This is an eco-friendly replacement of conventional reagents based on toxic compounds such as vanadium and nitrous oxide. The line includes both the most powerful reagent and the mildest one. They are promising for the synthesis of new polymers and in more extent for the pharmaceutical industry that uses reagents based on heavy metals in producing medications.
