Magnetic monopoles detected in Kagome spin ice systems

Magnetic monopoles are actually impossible. At low temperatures, however, certain crystals can contain so-called quasi-particles that behave like magnetic monopoles. Now an international cooperation has proven that such monopoles also occur in a Kagome spin ice system. Continue Reading at ScienceDaily.com Click Here.

The evolution of color: How butterfly wings can shift in hue

A selective mating experiment by a curious butterfly breeder has led scientists to a deeper understanding of how butterfly wing color is created and evolves. Continue Reading at ScienceDaily.com Click Here.

Protecting the high seas: Identify biodiversity hotspots

Researchers use big data to identify biodiversity hotspots that could become the first generation of high seas marine protected areas. Continue Reading at ScienceDaily.com Click Here.

Targeting tumors: Synthesis against the clock

Radiolabeled molecules help nuclear physicians to detect and precisely target tumors, which are often developing due to pathological changes in metabolic processes. Using positron emission tomography, scientists have now developed the first radiotracer labelled with the fluorine isotope 18F, which can visualize special transport proteins often found in the cell membranes of cancer cells. The…

Surgical masks likely good for most COVID-19 treatment

A systematic review of four randomized controlled trials on masks done between 1990 and last month shows the use of medical masks did not increase viral respiratory infection or clinical respiratory illness. Continue Reading at ScienceDaily.com Click Here.

COVID-19: On average only 6% of actual SARS-CoV-2 infections detected worldwide

The number of confirmed cases of coronavirus disease officially issued by countries dramatically understates the true number of infections, a report suggests. Researchers used estimates of COVID-19 mortality and time until death from a recent study to test the quality of records. This shows that countries have only discovered on average about 6% of infections.…

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.

US modelling study estimates impact of school closures for COVID-19 on US health-care workforce and associated mortality

US policymakers considering physical distancing measures to slow the spread of COVID-19 face a difficult trade-off between closing schools to reduce transmission and new cases, and potential health-care worker absenteeism due to additional childcare needs that could ultimately increase mortality from COVID-19, according to new modelling research.

Deep-sea worms and bacteria team up to harvest methane

Scientists uncover an unusual partnership at the bottom of the ocean. Continue Reading at ScienceDaily.com Click Here.

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…

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…

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. Continue Reading at ScienceDaily.com Click Here.
