WEST LAFAYETTE, Ind. - Purdue University innovators are working on inventions to use micro-chip technology in implantable devices and other wearable products such as smart watches to improve biomedical devices, including those used to monitor people with glaucoma and heart disease.
New research into people's coping strategies faced with COVID-19 highlights the mental health toll for those shielding
Coronavirus and the imposition of lockdown this year 'significantly raised' mental health challenges, particularly so for the most vulnerable groups, including those shielding, according to the first study to look at people's coping styles in face of the pandemic.
The RCP 8.5 C02 emissions pathway, long considered a "worst case scenario" by the international science community, is the most appropriate for conducting assessments of climate change impacts by 2050, according to a new article published today in the Proceedings of the National Academy of Sciences. The work was authored by Woods Hole Research Center (WHRC) Risk Program Director Dr. Christopher Schwalm, Dr. Spencer Glendon, a Senior Fellow at WHRC and founder of Probable Futures, and by WHRC President Dr. Philip Duffy.
The COVID-19 pandemic has led to severe financial stress for both hospitals and physician practices, raising serious concerns that many may either close or be purchased by larger organizations. Such consolidation is well-recognized to lead to higher prices. Whether it will lead to better quality of care is less clear.
Published in Advanced Functional Materials, a University of Sydney team of biomedical engineers has developed a plasma technology to robustly attach hydrogels - a jelly-like substance which is structurally similar to soft tissue in the human body - to polymeric materials, allowing manufactured devices to better interact with surrounding tissue.
To function optimally in the body, a manufactured implant - whether it be an artificial hip, a fabricated spinal disc or engineered tissue - must bond and interact with appropriate surrounding tissues and living cells.
MANHATTAN, KANSAS -- Yunjeong Kim and Kyeong-Ok "KC" Chang, virologists in the College of Veterinary Medicine at Kansas State University, have published a study showing a possible therapeutic treatment for COVID-19.
Pathogenic coronaviruses are a major threat to global public health, as shown by severe acute respiratory syndrome coronavirus, or SARS-CoV; Middle East respiratory syndrome coronavirus, known as MERS-CoV; and the newly emerged SARS-CoV-2, the virus that causes COVID-19 infection.
Prey can evade predators and also avoid attacks. However, some can escape after a successful attack, that is, from inside a predator after being swallowed. For example, some animals that can survive predators' digestive systems are excreted in feces and thereby escape, albeit in a passive manner. Now, for the first time, research has documented the quick, active escape of prey from the body of a predator after being eaten.
Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism.
The study, published in the Journal of Neuroscience, found that paying attention can change how the brain allocates its limited energy; as the brain uses more energy in processing what we attend to, less energy is supplied to processing outside our attention focus.
Four stranded DNA structures - known as G-quadruplexes - have been shown to play a role in certain types of breast cancer for the first time, providing a potential new target for personalised medicine, say scientists at the University of Cambridge.
CNRS researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalise iron. Published in Nature Chemistry (August 3rd, 2020), this work shows that the absorbed iron allows cancer cells to acquire metastatic properties.
Scientists at UCL have discovered new biomarkers, which may identify those people with Type 1 diabetes who would benefit from the immunotherapy drug Abatacept, a finding which could eventually help thousands manage the disease more effectively.
Type 1 diabetes is an autoimmune disease, which means it is caused by the body's own immune system attacking healthy body tissues. People with the condition are unable to produce the hormone insulin, which is essential to control and use glucose as energy.
CABI scientists have conducted research which is calling for an urgent integrated management strategy, including biological control, to fight the invasive weed Mimosa diplotricha which is threatening livelihoods in eastern and southern Africa
Hershey, Pa. -- Cannabinoid-containing products may alter the effects of some prescription drugs, according to Penn State College of Medicine researchers. They published information that could help medical professionals make safe prescribing choices for their patients who use prescription, over-the-counter or illicit cannabinoid products.
The University of Kent's School of Biosciences and the Institute of Medical Virology at Goethe-University, Frankfurt am Main, have identified that a glycoprotein known as transferrin may critically contribute to severe forms of COVID-19.
A test which detects changing levels of tumour fragments in the blood may be an easy, non-invasive and quick way to predict who will benefit from immunotherapy, a treatment option for advanced cancers.
Although immunotherapy has been shown to shrink tumours and prolong survival for patients for whom other treatments have failed, about 20-30% of patients benefit from it. Clinicians don't yet know ahead of time who this subset of patients is.
