Tropical Cyclone Trevor appeared to have a cloud-filled eye in visible imagery from NASA-NOAA's Suomi NPP satellite.

MINNEAPOLIS - Some studies have suggested that people who are younger when they enter puberty are more likely to later develop multiple sclerosis (MS). But a new study attributes that link to body mass index (BMI). The study is published in the March 20, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

(Millbrook, NY) In the Americas, primate species likely to harbor Zika - and potentially transmit the virus - are common, abundant, and often live near people. So reports a new study published today in Epidemics. Findings are based on an innovative model developed by a collaborative team of researchers from Cary Institute of Ecosystem Studies and IBM Research through its Science for Social Good initiative.

Polyiodides exhibit useful electrochemical properties such as charge-carrier transportation, high electrolyte energy density, high redox reaction reversibility and a wide range of electrical conductivity, all depending on the forces exerted by the organic counter ions--chemical pressure. For this reason, polyiodides have been used in technical applications in electronic and electrochemical devices such as flow batteries, fuel cells, dye sensitized solar cells and optical devices.

EVANSTON, Ill. --- Women who shared their mother's womb with a male twin are less likely to graduate from high school or college, have earned less by their early 30s, and have lower fertility and marriage rates when compared with twins who are both female, according to new Northwestern University research.

Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater from San Francisco Bay.

The findings, published March 18 in Proceedings of the National Academy of Sciences, demonstrate a new way of separating hydrogen and oxygen gas from seawater via electricity. Existing water-splitting methods rely on highly purified water, which is a precious resource and costly to produce.

EAST LANSING, Mich. - Scientists studying monarch butterflies have traditionally focused on two sources for their decline - winter habitat loss in Mexico and fewer milkweed plants in the Midwest.

Tropical Cyclone Trevor formed in the Coral Sea of the Southwestern Pacific Ocean on March 18. NASA's Terra satellite analyzed cloud top temperatures in the storm which gave an indication of the storm's strength. Trevor has already triggered warnings in Queensland, Australia.

Tropical Cyclone Savannah weakened and "lost" its eye as high clouds filtered over it. NASA-NOAA's Suomi NPP satellite passed over the Southern Indian Ocean and captured a visible image of the tropical storm that revealed high clouds had moved over its eye.

Wind shear weakened Tropical Storm Savannah and satellite imagery showed that it had become slightly elongated with clouds pushing southeast of the center. In general, wind shear is a measure of how the speed and direction of winds change.

Visible imagery from NASA's Terra satellite showed Tropical Cyclone continued to move in a westerly direction after making landfall in Mozambique.

On March 15, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Idai. The imagery showed the storm centered over central Mozambique and its western quadrant had already spread into Zimbabwe. Even over land, the system still showed a ragged eye on microwave satellite imagery.
