As people increasingly social distance themselves to prevent the spread of the novel coronavirus, social media is an appealing way to stay in contact with friends, family and colleagues. But it can also be a source of misinformation and bad advice – some of it even dangerously wrong.

Drug therapies that help older adults maintain their skeletal muscle mass and physical function for longer could be a step closer after researchers at the University of Birmingham identify a key mechanism that drives the clearance of damaged mitochondria.
A team in the University's School of Sport, Exercise and Rehabilitation Sciences are well-versed at investigating dynamic machinery within cells called mitochondria. Mitochondria act as the power plant in every cell and help to supply energy for all living things.
(New York City. March 20, 2020.) A study by investigators at Hospital for Special Surgery (HSS) has discovered a molecule in the lymphatic system that has the potential to play a role in autoimmune disease. The study, “Lymph node stromal CCL2 limits antibody responses,” was published online today in the journal Science Immunology.
Lead investigator Theresa Lu, MD, PhD, senior scientist in the Autoimmunity and Inflammation Program at the HSS Research Institute, and colleagues launched the study to gain a better understanding of how the immune system works.
Wealthy, white California counties--once considered the nation's hotbeds for autism spectrum disorder (ASD)--have seen prevalence flatten or fall in the last two decades, while rates among poor whites and minorities keep ticking up, new CU Boulder research has found.
The study, published March 19 in the Journal of Autism and Developmental Disorders, raises the possibility that parents in wealthier counties are successfully reducing environmental exposures that may contribute to autism risk, or taking other steps to curb its severity early on.
The virus that causes COVID-19 remains for several hours to days on surfaces and in aerosols, a new study published in the New England Journal of Medicine found.
The study suggests that people may acquire the coronavirus through the air and after touching contaminated objects. Scientists discovered the virus is detectable for up to three hours in aerosols, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.
Oncotarget Volume 11, Issue 11 reported that relapsed APL, particularly in the high-risk subset of patients, remains an important clinical problem.
The probability of relapse is significantly higher in the high-risk subset of patients undergoing treatment for APL; overall approximately 10-20% of APL patients relapse regardless of their risk stratification.
A standardised test that can now be used in the seven main languages in India will support the diagnosis of dementia and mild cognitive impairment.
Researchers have adapted the Addenbrooke's Cognitive Examination (ACE-III), a well-known screening instrument for dementia detection/diagnosis, to be used in Hindi, Telugu, Kannada, Malayalam, Urdu, Tamil and Indian English.
WEST LAFAYETTE, Ind. -- Similarly to how a picked lock gives away that someone has broken into a building, the stiffening of a structure surrounding cells in the human body can indicate that cancer is invading other tissue.
Monitoring changes to this structure, called the extracellular matrix, would give researchers another way to study the progression of disease. But detecting changes to the extracellular matrix is hard to do without damaging it.
A study has uncovered a new neurodegenerative disorder in which children experience developmental regression and severe epilepsy.
The study, led by the Murdoch Children's Research Institute (MCRI) and published in The American Journal of Human Genetics, found a variation in a gene causes a severe childhood-onset neurodegenerative disorder that has never before been described.
A Giant Right Atrial Myxoma with Blood Supply from the Left and Right Coronary Arteries: Once in a Blue Moon
In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2019.0566, Yichao Xiao, Zhenfei Fang, Xinqun Hu, Qiming Liu, Zhaowei Zhu, Na Liu, Xiaofan Peng and Shenghua Zhou from the Department of Cardiology, The Second Xiangya Hospital of Central South University, Changsha, Hunan, China consider Cardiac myxomas.
Lasers are becoming one of the dominant tools in the current manufacturing industry. Much effort has been devoted to improving the processing accuracy, and spatial resolutions as low as micrometers have been achieved in laser cutting, wedding, marking and stereolithography in an atmospheric environment. The femtosecond laser (fs-laser) is a particularly promising approach from this point of view, in addition to its three-dimensional (3D) processing capability and broad-spectrum material usability.
The retrieval of phase of electromagnetic fields is one of the most important problems in optics as it allows the shape of transparent objects, including cells, to be quantified using visible light. Phase is a quantity that relates to the wave nature of light; it is not directly detectable by our eyes or common cameras, and yet carries important information about objects the light went through. Measuring the phase with very little light can be even more interesting and useful.
Researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), working with an international network of scientists, have identified an inflammatory regulatory circuit in the eye controlled by a subtype of endothelial cells, the cells that line the interior of blood vessels. The discovery was made by analyzing gene expression in 8000 cells of the choroid--the vascular layer at the rear of the eye between the retina and the sclera.
The marine heatwave of 2016 was one of longest and hottest thermal anomalies recorded on the Great Barrier Reef in Australia, influencing multiple species of marine ectotherms, including coral reef fishes.
Sugars like polysaccharides are found everywhere in nature and are believed to be essential for life to arise. In humans, they cover the surface of all cells and the family of polysaccharides called GAGs (glycosaminoglycans) are particularly abundant and difficult to analyse.
