Lessons learned from addressing myths about Zika and yellow fever outbreaks in Brazil

When disease epidemics and outbreaks occur, conspiracy theories often emerge that compete with the information provided by public health officials. A new study finds that information used to counter myths about Zika in Brazil not only failed to reduce misperceptions but also reduced the accuracy of people's other beliefs about the disease.

Ultrafast probing reveals intricate dynamics of quantum coherence

Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations. Researchers found that low-energy and high energy states are correlated in a layered, superconducting material. Exciting the material with an ultrafast beam of near-infrared light produces coherent excitations lasting a surprisingly 'long' time of around 500 femtoseconds, originating from a quantum superposition of excited states within the crystal.

Going super small to get super strong metals

Metals get stronger as the size of the grains making up the metal get smaller -- up to a point. If the grains are smaller than 10 nanometers in diameter the materials are weaker because, it was thought, they slide past each other like sand sliding down a dune. But in samples of nickel with grain diameters as small as 3 nanometers, and under high pressures, the strength of the samples continued to increase with smaller grain sizes.

While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath the surface and have been able to suggest that its core contains moderate amounts of sulfur, oxygen and hydrogen as light elements.

Risk of coronavirus importation in Africa

Egypt, Algeria and Republic of South Africa are the African countries most at risk for coronavirus COVID-19 importation in the continent, due to high air traffic with the contaminated Chinese provinces. But these countries are also among the best equipped on the continent to quickly detect and deal with new cases. In other African countries, the risk of importation is lower, but health organization deficiencies raise concerns about rapid spread.
