Saliva test for cannabis could someday help identify impaired drivers

Those who consume alcohol and drive are often subjected to roadside stops, breathalyzer tests and stiff penalties if their blood alcohol content exceeds certain limits. Currently, no such test exists for cannabis intoxication, although the substance can impair driving. Now, scientists report a convenient saliva test for cannabis levels that might someday be used at roadside stops.

A friendlier way to deal with nitrate pollution

Learning from nature, scientists have found a catalyst that efficiently transforms nitrate into nitrite — an environmentally important reaction — without requiring high temperature or acidity, and now have identified the mechanism that makes this efficiency possible.

New artificial intelligence system can empower medical professionals in diagnosing skin diseases

Researchers have developed a deep learning-based artificial intelligence (AI) algorithm that can accurately classify cutaneous skin disorders, predict malignancy, suggest primary treatment options, and serve as an ancillary tool to enhance the diagnostic accuracy of clinicians. With the assistance of this system, the diagnostic accuracy of dermatologists as well as the general public was significantly improved.

Reconstructing the clock of human development

Researchers used iPS cells to reconstructed the human ‘segmentation clock,’ a key point in early embryonic development that determines how the body gets segmented. The ‘segmentation clock’ is a genetic oscillator that controls and guides the emergence of ‘somites,’ distinct collections of cells that contribute to the formation of the vertebrae and ribs. Segmentation clock genes a have been studied extensively in many animals, except humans.

Using sponges to wipe out cancer

Manzamine A, a natural product derived from certain groups of sponges, can block the growth of cervical cancer cells, report researchers. Manzamine A targets a protein that is highly expressed in many cancers, including cervical cancer, and is the first reported inhibitor of this protein.

Possible coronavirus drug identified

A new study has shown that an anti-parasitic drug already available around the world can kill the virus within 48 hours. Scientists found that a single dose of the drug, Ivermectin, could stop the SARS-CoV-2 virus growing in cell culture. The next steps are to determine the correct human dosage — ensuring the doses shown to effectively treat the virus in vitro are safe for humans.

The desire for information: Blissful ignorance or painful truth?

A new study looks closely at why many people are so likely to avoid useful information — even if it benefits their health. While creating a test that allows anyone to test their own preferences for seeking out or avoiding info, our researchers found, among other things, that impatient people are more likely to avoid learning information, preferring to avoid the prospect of immediate pain rather than make better long-term decisions.

New wastewater treatment process removes health hazardous chemicals

A research team has developed a novel wastewater treatment system that can effectively remove conventional pollutants, and recover valuable resources such as phosphorus and organic materials. This novel system combines chemically enhanced primary sedimentation of sewage with acidogenic fermentation of sludge in tandem, can effectively remove trace emerging chemical contaminants from wastewater and is more cost effective compared with conventional wastewater treatment systems.

Using fiber optics to advance safe and renewable energy

Fiber optic cables, it turns out, can be incredibly useful scientific sensors. Researchers have studied them for use in carbon sequestration, groundwater mapping, earthquake detection, and monitoring of Arctic permafrost thaw. Now they have been awarded new grants to develop fiber optics for two novel uses: monitoring offshore wind operations and underground natural gas storage.

China’s control measures may have prevented 700,000 COVID-19 cases

China’s control measures during the first 50 days of the COVID-19 epidemic may have delayed the spread of the virus to cities outside of Wuhan by several days and prevented more than 700,000 infections nationwide, according to an international team of researchers. The findings could be useful to countries that are still in early phases of the COVID-19 outbreak.

Ecosystem services are not constrained by borders

What do chocolate, migratory birds, flood control and pandas have in common? Many countries benefit from ecosystem services provided outside their nations. This can happen through economic relationships, biological and geographical conditions, but we hardly know how and where these ecosystem service flows occur. Scientists show how interregional ecosystem service flows can be identified and quantified.

How important is speech in transmitting coronavirus?

Normal speech by individuals who are asymptomatic but infected with coronavirus may produce enough aerosolized particles to transmit the infection, according to aerosol scientists. Although it’s not yet known how important this is to the spread of COVID-19, it underscores the need for strict social distancing measures — and for virologists, epidemiologists and engineers who study aerosols and droplets to work together on this and other respiratory diseases.

New temperature sensing mechanism in plants

Cell biologists reveal the phytochrome B molecule has unexpected dynamics activated by temperature, and behaves differently depending on the temperature and type of light. As climate change warms the world, crop growth patterns and flowering times will change. A better understanding of how phytochromes regulate the seasonal rhythms of plant growth will help scientists develop crops for optimal growth under the new climate and might shed light on cancer in animals.

Renewable energy developments threaten biodiverse areas

More than 2000 renewable energy facilities are built in areas of environmental significance and threaten the natural habitats of plant and animal species across the globe. A research team mapped the location of solar, wind and hydropower facilities in wilderness, protected areas and key biodiversity areas.

Wearing surgical masks in public could help slow COVID-19 pandemic’s advance

Surgical masks may help prevent infected people from making others sick with seasonal viruses, including coronaviruses, according to new research. In laboratory experiments, the masks significantly reduced the amounts of various airborne viruses coming from infected patients, measured using the breath-capturing ‘Gesundheit II machine’ developed by Dr. Don Milton, professor in the University of Maryland School of Public Health and a senior author of the study published April 3 in the journal Nature Medicine.

A twist connecting magnetism and electronic-band topology

Materials that combine topological electronic properties and quantum magnetism are of high current interest, for the quantum many-body physics that can unfold in them and for possible applications in electronic components. For one such material, physicists have now established the microscopic mechanism linking magnetism and electronic-band topology.

Treating COVID-19 in a patient with multiple myeloma

A case study of a patient in Wuhan, China, suggests that the immunosuppressant tocilizumab may be an effective COVID-19 treatment for very ill patients who also have multiple myeloma and other blood cancers. The report also suggests that blood cancer patients may have atypical COVID-19 symptoms.
