Trapped saltwater caused mangrove death after Hurricane Irma

When Hurricane Irma hit southern Florida in September of 2017, the storm buffeted coastal mangrove forests with winds over 116 mph—strong enough to rip off leaves, break branches, and snap tree trunks in half. Of the mangrove forest damaged by Hurricane Irma, about 83% recovered after the first year. But the rest didn't, leaving scientists wondering...

Deep learning and holography create a better point-of-care sensor

Agglutination assays are widely used immunological sensors based on antigen-antibody interactions that result in clumping of antibody-coated microscopic particles. Once the sample—for example, a patient's serum—is introduced, the corresponding target antigens in the sample rapidly attach to the antibody binding sites and the particles start to form...

New DNA study provides critical information on conserving rainforest lizards

A study published June 16 in Biotropica by a team of researchers at the University of Washington, the UW Burke Museum of Natural History and Culture, WWF Hong Kong and the University of Colombo has provided an important road map to conserving rough-nosed horned lizards in Sri Lanka.

Team uses 3D printing to optimize flow-through electrodes for electrochemical reactors

To take advantage of the growing abundance and cheaper costs of renewable energy, Lawrence Livermore National Laboratory (LLNL) scientists and engineers are 3D printing flow-through electrodes (FTEs), core components of electrochemical reactors used for converting CO2 and other molecules to useful products.

Finding the cause of a fatal problem in rocket engine combustors

Rocket engines contain confined combustion systems, which are essentially combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, sound waves, and heat produced from chemical reactions cause an unstable phenomenon called "combustion oscillations." The force of these oscillations on the body of the combustion...

How we see better by 'looking away'

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent study conducted at the University of Bonn (Germany), published in the journal Current Biology. The researchers observed such offsets...

New model tracks carbon in agroecosystems

Carbon is everywhere. It's in the atmosphere, in the oceans, in the soil, in our food, in our bodies. As the backbone of all organic molecules that make up life, carbon is a very accurate predictor of crop yields. And soil is the largest carbon pool on earth, playing an important role in keeping our climate stable.

Researchers use virtual reality to demonstrate effectiveness of 3D visualization as a learning tool

Researchers from the Neuroimaging Center at NYU Abu Dhabi (NYUAD) and Wisconsin Institute for the Discovery at University Wisconsin-Madison have developed the UW Virtual Brain Project, producing unique, interactive, 3D narrated diagrams to help students learn about the structure and function of perceptual systems in the human brain. A new study exploring...

Why is this weird, metallic star hurtling out of the Milky Way?

About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star, known as LP 40−365, is one of a unique breed of fast-moving stars—remnant pieces of massive white dwarf stars—that have survived in chunks after a gigantic stellar explosion.

Overfishing and other human pressures are severely harming marine protected areas worldwide

A new study by Tel Aviv University reveals significant ecological damage to many MPAs around the world. The study findings point to a strong "edge effect" in MPAs, i.e. a sharp 60% reduction in the fish population living at the edges of the MPA (up to a distance of 1-1.5 km within the MPA) compared to core areas. The "edge effect" significantly diminishes...
