DURHAM, N.C. - Biomedical engineers at Duke University have demonstrated that a class of interwoven composite materials called semi-interpenetrating polymer networks (sIPNs) can be produced by living cells. The approach could make these versatile materials more biologically compatible for biomedical applications such as time-delayed drug delivery systems.
The research appears online on June 8 in the journal Nature Communications.
Humans expect that AI is Benevolent and trustworthy. A new study reveals that at the same time humans are unwilling to cooperate and compromise with machines. They even exploit them.
Picture yourself driving on a narrow road in the near future when suddenly another car emerges from a bend ahead. It is a self-driving car with no passengers inside. Will you push forth and assert your right of way, or give way to let it pass? At present, most of us behave kindly in such situations involving oth-er humans. Will we show that same kindness towards autonomous vehicles?
As COVID-19 restrictions ease nationwide and more people host indoor gatherings, investing in a high efficiency particulate air (HEPA) purifier might not be a bad idea, says a University of Cincinnati College of Medicine researcher.
Several published studies evaluating aerosols and submicron particles similar in size to the SARS-CoV-2 virion have shown that portable HEPA purifiers are able to significantly reduce airborne COVID-19 particles, says Ahmad Sedaghat, MD, PhD, director of the UC Division of Rhinology, Allergy and Anterior Skull Base Surgery.
New Orleans, LA - Research conducted at LSU Health New Orleans Neuroscience Center of Excellence reports that Elovanoids, bioactive chemical messengers made from omega-3 very-long-chain polyunsaturated fatty acids discovered by the Bazan lab in 2017, may block the virus that causes COVID-19 from entering cells and protect the air cells (alveoli) of the lung. Their findings are published online in Scientific Reports, available here.
Fraud is going uninvestigated by police who are "hiding behind the veil" of the Action Fraud national crime reporting agency.
In his paper published this week in Policing, Professor Mark Button, director of the Centre for Counter Fraud Studies at the University of Portsmouth argues that, Action Fraud, which has been widely derided, has become a useful veil from which the police can hide their inadequate response.
For two decades, the number of Americans who die each year from drug overdoses has steadily risen, from less than 20,000 in 1999 to more than 80,000 in 2020. By studying patterns of these drug-related fatalities, researchers at University of California San Diego School of Medicine, San Diego State University (SDSU), and international collaborators have designed and validated a prediction model to signal counties at risk of future overdose death outbreaks. The goal of the open-source tool is to predict and prevent deaths through early deployment of public health resources.
Medulloblastoma is a rare but devastating childhood brain cancer. This cancer can spread through the spinal fluid and be deposited elsewhere in the brain or spine. Radiation therapy to the whole brain and spine followed by an extra radiation dose to the back of the brain prevents this spread and has been the standard of care. However, the radiation used to treat such tumors takes a toll on the brain, damaging cognitive function, especially in younger patients whose brains are just beginning to develop.
Increasing evidence shows that physical activity and exercise training may delay or prevent the onset of Alzheimer's disease (AD). In aging humans, aerobic exercise training increases gray and white matter volume, enhances blood flow, and improves memory function. The ability to measure the effects of exercise on systemic biomarkers associated with risk for AD and relating them to key metabolomic alterations may further prevention, monitoring, and treatment efforts.
Scientists say naked mole rats - a rodent native to West Africa - may hold the key to new treatments for degenerative diseases such as cancer and dementia.
The reclusive animals have a lifespan far in excess of other rodents - for example, mice and rats live about two years, whereas naked mole rats can live for 40 or 50 years.
Researchers at the University of Bradford say the animals have a unique DNA repair mechanism that enables them to prevent cancers and other degenerative conditions, including dementia.
Cancer resistant
People often think about human behavior in terms of what is happening in the present--reading a newspaper, driving a car, or catching a football. But other dimensions of behavior extend over weeks, months, and years.
Examples include a child learning how to read; an athlete recovering from a concussion; or a person turning 50 and wondering where all the time has gone. These are not changes that people perceive on a day-to-day basis. They just suddenly realize they're older, healed, or have a new development skill.
Researchers at Michigan Medicine found a subset of middle-aged men with cerebral palsy are up to 5.6 times more likely to suffer fractures than men without the disorder.
"We are not really sure why this happens," said Edward A. Hurvitz, M.D., professor and chair of the Michigan Medicine Department of Physical Therapy and Rehabilitation. "It may be related to structural differences that occur during adolescent growth, or to greater bone mineral loss at earlier age for people with cerebral palsy compared to peers."
JUNE 10, 2021, NEW YORK - A Ludwig Cancer Research study adds to growing evidence that immune cells known as macrophages inhabiting the body cavities that house our vital organs can aid tumor growth by distracting the immune system's cancer-killing CD8+ T cells.
AMP recommends minimum set of pharmacogenetic alleles to guide clinical CYP2D6 genotype testing, pro
ROCKVILLE, Md. - June 10, 2021 - The Association for Molecular Pathology (AMP), the premier global, molecular diagnostic professional society, today published consensus recommendations to aid in the design and validation of clinical CYP2D6 assays, promote standardization of testing across different laboratories and improve patient care.
(Boston)--Medical education aspires to mitigate bias in future professionals by providing a robust curriculum that includes perspectives and practices for caring for sexual and gender minority (SGM) populations, including lesbian, gay, bisexual, transgender and intersex (LGBTQI) persons. To provide medical schools with a more systematic, uniform approach to teaching these topics in their curriculum, the Association of American Medical Colleges (AAMC) in 2014 published 30 SGM competencies and topics that curricula should address.
Breakthrough in metamaterials: for the first time in the world, researchers at Tel Aviv University developed an innovative nanotechnology that transforms a transparent calcite nanoparticle into a sparkling gold-like particle. In other words, they turned the transparent particle into a particle that is visible despite its very small dimensions. According to the researchers the new material can serve as a platform for innovative cancer treatments.
