Research highlights how forensic anthropological work mistakenly supports racial differences

Forensic anthropologists analyze skeletal remains to help identify people. A new study highlights how this work, specifically dealing with ancestry, may inadvertently support the idea that racial differences are biological.

COVID-19 pandemic illuminates the importance of airborne transmission of respiratory viruses

SARS-CoV-2, the virus behind today's global coronavirus pandemic, spreads primarily by inhalation of virus-laden aerosols at both short and long ranges - and a comprehensive new assessment of respiratory viruses finds that many others probably do as well.

Studies offer insight into how the human body develops and acquires mutations throughout life

New insights into how the human body develops from one cell into trillions, and the genetic mutations that cells pick up along the way, have been generated by two studies from scientists at the Wellcome Sanger Institute, the University of Cambridge and their collaborators.

Why have COVID-19 caseloads been comparatively low in Africa?

A new study has been published in the International Journal of Environmental Research and Public Health that highlights the potential lessons that the world can draw from Africa on assumptions concerning viral pandemics. This is particularly important, given Africa’s long experience with dangerous infectious diseases.

How do glycans affect SARS-CoV-2 spike protein openings?

In a paper recently uploaded to the bioRxiv* preprint server, the role of glycan coating on the SARS-CoV-2 spike protein is further investigated by molecular dynamics simulations of the glycosylated and non-glycosylated protein, identifying several key glycans that play a role in stabilizing and protecting the RBD, and also encourage bonding with the ACE2 receptor.

New bioengineered lung model could help scientists to advance research in lung conditions

An interdisciplinary team of researchers from McMaster and SickKids are developing a cutting-edge lung model that can better respond to viruses and drug treatments, giving scientists a tool to advance research in lung conditions like COVID-19, cystic fibrosis and allergens for asthma and air pollution.

Treatment with stem cell grafts promotes tendon healing in sheep

Tendon injuries in sheep that were treated with stem cell grafts achieved, in just two months, a diameter and hardness similar to the original healthy tendon, according to the results of a study released in STEM CELLS Translational Medicine.

Direct evidence in hamsters shows SARS-CoV-2 is airborne

Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted without contact by respiratory droplets and aerosols bearing the virus when coughing, sneezing, speaking, and breathing. The virus has been cultured from aerosols collected nearby COVID-19 patients, and such aerosols can linger in still air for hours.

Excess COVID-19 cases, deaths in the U.S. may be attributable to PM2.5 pollution from wildfires

Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health.

Study finds new pair of gene variants that causes sudden onset of hypertension in pregnant women

An international study, led by researchers from Queen Mary University of London and St Bartholomew's Hospital, has found a unique pair of gene variants that causes sudden onset high blood pressure in pregnant women.

SARS-CoV-2 detection by machine learning surface-enhanced Raman spectroscopy

Surface-enhanced Raman spectroscopy is a highly sensitive molecule characterization method, significantly more sensitive than ordinary Raman spectroscopy due to the excitation of Raman modes matching the plasmon resonance frequency of the surface metal utilized, usually gold, silver, or copper.

New research offers hope to increase efficacy of immunotherapy for lung cancer

Lung cancer is the leading cause of cancer-related death. Current treatments employ immunotherapy, often in combination with chemotherapy, but benefits to patients remain slight.

Plant-based virus-like particle vaccine induces durable immune response against SARS-CoV-2 variants

Scientists from Germany and Belgium have recently described the immunogenicity of a plant-based virus-like particle vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The vaccine induces robust antibody and T cell responses for at least 6 months. Moreover, the vaccine demonstrates potent neutralizing efficacy against the B.1.1.7, B.1.351, and P1 variants of SARS-CoV-2.

Tiny tumbling soft robots could precisely deliver drugs to central nervous system

Would you let a tiny MANiAC travel around your nervous system to treat you with drugs? You may be inclined to say no, but in the future, "magnetically aligned nanorods in alginate capsules" (MANiACs) may be part of an advanced arsenal of drug delivery technologies at doctors' disposal.
