Cannabis plant may harbor SARS-CoV-2 for at least a week

Researchers at the Medicinal Genomics Corporation have warned that cannabis flowers exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may harbor the virus for at least seven days.

New test can detect the RNA of SARS-CoV-2 in patient samples in 30 minutes

A new diagnostic test can detect the RNA of SARS-CoV-2, the virus that causes COVID-19, in urine, blood, saliva or mouth swab samples in just 30 to 45 minutes, according to a new study published June 12, 2020 in the open-access journal PLOS ONE by Laura Lamb of the Beaumont Health System, Michigan, USA, and colleagues.

Experts analyze the effects two decades after a mining spill

A group of experts from the University of Seville has carried out a comparative study of the concentrations, both totals as well as fractions, of the metals found in sediment in the River Guadiamar in 2002 with those present in the same area in 2018.

Facemasks will prevent COVID-19 in the "new normal"

The coronavirus disease (COVID-19) has left many countries grappling with high infection rates. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has negatively impacted societies and economies. Now though, many countries are starting to lift restrictions to prepare for a "new normal."

Lockdowns combined with widespread use of facemasks can stop the resurgence of SARS-CoV-2

Population-wide use of facemasks keeps the coronavirus 'reproduction number' under 1.0, and prevents further waves of the virus when combined with lockdowns, a modelling study from the universities of Cambridge and Greenwich suggests.

Anti-RBD antibodies shown to neutralize active SARS-CoV-2

A new study published on the preprint server bioRxiv* in June 2020 reports the discovery of multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in samples from healthy donors, collected before the pandemic. These antibodies are capable of inhibiting the binding of the spike protein of the virus to the angiotensin-converting enzyme 2 (ACE2) molecule and can neutralize active infection of cells in culture.

Irradiation with UV light kills SARS-CoV-2

Researchers in Italy have found that it is possible to completely inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using short-wavelength UV (UV-C) irradiation.

New advance in wearable sensing could detect and quantify many biological conditions

Researchers at Tufts University's School of Engineering have developed biomaterial-based inks that respond to and quantify chemicals released from the body (e.g. in sweat and potentially other biofluids) or in the surrounding environment by changing color.

Researchers are developing portable device to detect the presence of PFAS in water

Potentially harmful man-made chemicals used in firefighting foam and consumer products have contaminated groundwater and even private wells near military, industrial and disposal sites across the country - including Joe Foss Field and Ellsworth Air Force Base in South Dakota.

Showers, toilets and washbasins may act as SARS-CoV-2 reservoirs despite low environmental transmission

In their new research paper currently available on the medRxiv* preprint server, scientists from the University of Bonn in Germany demonstrated that indirect environmental transmission most likely plays only a minor role in the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, certain potentially neglected viral reservoirs have to be taken into account when introducing epidemiological measures.

COVID-19 patients exhale millions of viral particles per hour

An international team of researchers reports that patients with coronavirus disease 2019 (COVID-19) release thousands of viral particles directly into the air simply though breathing.

Common assumptions about mercury exposure should be reexamined, show studies

Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore but also to downstream communities hundreds of kilometers away from where people eat mercury-contaminated river fish as part of their diet.

Type 2 diabetes is more prevalent in American Indians and Alaska Natives

Type 2 diabetes (T2D) affects American Indians and Alaska Natives at approximately three times the rate of white Americans and is closely linked to the disproportionately high rates of cardiovascular diseases such as heart attacks and strokes, according to the American Heart Association Scientific Statement "Cardiovascular Health in American Indians and Alaska Natives," published today in the Association's flagship journal Circulation.
