Record solar hydrogen production with concentrated sunlight

This is Sophia Haussener, leading the project, Saurabh Saurabh Tembhurne and Fredy Nandjou. Credit: Marc Delachaux / EPFL Hydrogen will play a key role in reducing our dependence on fossil fuels. It can be sustainably produced by using solar energy to split water molecules. The resulting clean energy can be stored, used to fuel cars…

Credit: Seattle Children's Scientists at Seattle Children's Research Institute are paving the way to use gene-edited B cells -- a type of white blood cell in the immune system -- to treat a wide range of potential diseases…

New artificial synapse is fast, efficient and durable

An array of artificial synapses designed by researchers at Stanford and Sandia National Laboratories can mimic how the brain processes and stores information. Credit: Armantas Melianas and Scott Keene The brain's capacity for simultaneously learning and memorizing large amounts of information while requiring little energy has inspired an entire field to pursue brain-like -- or…

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds

The hydrogen atom (blue) hits the graphene surface (black) and forms an ultra-fast bond with a carbon atom (red). The high energy of the impinging hydrogen atom is first absorbed by neighboring carbon atoms (orange and yellow) and then passed on to the graphene surface in form of a sound wave Credit: Oliver Bünermann /…

Research sparks new insights on laser welding

Inside NIST's laser welding booth, a high-power laser melts a piece of metal to form the letters "NIST." Credit: Paul Williams/NIST On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of…

New inspection process freezes parts in ice

University of Cincinnati professor Francesco Simonetti developed a novel approach to inspecting manufactured parts that requires freezes them in ice. Credit: Corrie Stookey/CEAS Marketing "How on Earth did they make that?" asks Francesco Simonetti, commenting on an ice sculpture of a swan. Simonetti isn't admiring the artistry of shaping a block of ice into a…

How the immune system recognizes pathogens: Interaction Time

The use of light plays an important role for the researchers. Credit: Sascha Yousefi A team led by the Freiburg biologists Prof. Dr. Wolfgang Schamel and Prof. Dr. Wilfried Weber conducted an experiment in which they controlled the duration of the interaction of a specific protein with T cells, a type of white blood cells,…

Exploding electrical wires underwater to understand shock waves

Shock wave studies allow researchers to achieve the warm dense matter that's found only in the extreme conditions around stars and created in the laboratory for inertial confinement fusion research, and researchers in Israel recently set out to understand the relation, if any, between the evolution of a shock wave and the expansion of the…

Birds use social cues to make decisions

A zebra finch pair is inspecting a nest box. Credit: Hanja Brandl A new study in The Auk: Ornithological Advances suggests that some birds prioritize social information over visual evidence when making breeding choices. The quality of an environment can be difficult for a bird to assess and, therefore, continuously gathering information is a good…

What a dying star’s ashes tell us about the birth of our solar system

Billions of years ago, before our solar system was born, a dead star known as a white dwarf in a nearby binary star system accumulated enough material from its companion to cause it to 'go nova.' The stellar explosion forged dust grains with exotic compositions not found in our solar system. A team of researchers…

Ice feature on Saturn’s giant moon, TItan

This figure shows 3 orientations of Titan's globe. Mapped in blue is the icy corridor. Credit: NASA/JPL-Caltech/Space Science Institute Rain, seas and a surface of eroding organic material can be found both on Earth and on Saturn's largest moon, Titan. However, on Titan it is methane, not water, that fills the lakes with slushy raindrops.…
disease-causing-nibbling-amoeba-hides-by-displaying-proteins-from-host-cells

Disease-causing nibbling amoeba hides by displaying proteins from host cells

Entamoeba histolytica kills human cells through trogocytosis or "cell nibbling" where amoebae bite off and ingest fragments of human cells. UC Davis researchers Katherine Ralston, Hannah Miller and Rene Suleiman discovered that the amoebae use this process to acquire and display human cell membrane proteins on their own surface. This protects them from immune responses.…

Seagrass’ strong potential for curbing erosion

New research quantifies just how large and how dense a continuous meadow of seagrass must be to provide adequate damping of waves in a given geographic, climatic, and oceanographic setting. Credit: Courtesy of the researchers Most people's experience with seagrass, if any, amounts to little more than a tickle on their ankles while wading in…
