New discovery makes fast-charging, better performing lithium-ion batteries possible

Materials research -- published in Nature Communications -- makes possible lithium-ion batteries that can charge in a matter of minutes but still operate at a high capacity. Credit: Rensselaer Polytechnic Institute Creating a lithium-ion battery that can charge in a matter of minutes but still operate at a high capacity is possible, according to research…

CubeSats prove their worth for scientific missions

Only a few years ago, the astronomy and heliophysics communities were skeptical about whether CubeSats could reliably obtain scientific data. But these breadloaf-size satellites have proven their ability to return useful data. During the APS April Meeting 2019, Christopher S. Moore will describe how the twin Miniature X-ray Solar Spectometer CubeSats measure soft X-rays from…

Smart antioxidant-containing polymer responds to body chemistry, environment

A new drug-delivery system that contains crystalized catechin -- an antioxidant found in green tea and fruit -- can sense trouble and respond by releasing antioxidant to restore a normal heart rate to water fleas undergoing cardiac stress brought on by high oxidant levels.

Pyle Astronomers have discovered a third planet in the Kepler-47 system, securing the system's title as the most interesting of the binary-star worlds. Using data from NASA's Kepler space…

Engineers tap DNA to create ‘lifelike’ machines

Cornell professor of biological and environmental engineering Dan Luo and research associate Shogo Hamada have created a DNA material capable of metabolism, in addition to self-assembly and organization. Credit: John Munson/Cornell University Tapping into the unique nature of DNA, Cornell engineers have created simple machines constructed of biomaterials with properties of living things. Using what…

Certain microbes may reduce allergy-like reactions in many people

Cheese rind is removed from a wheel of ripening cheese. Iowa State University scientists are studying the bacteria in cheese rinds in an effort to reduce unpleasant reactions in people with histamine susceptibility. Credit: Monika Dzieciol Some aged cheeses cause allergy-like reactions in many people, but an Iowa State University scientist is working to identify…

Megalith tombs were family graves in European Stone Age

The Ansarve site on the island of Gotland in the Baltic Sea is embedded in an area with mostly hunter-gathers at the time.

Historic logging site shows first human-caused bedrock erosion along an entire river

The author's 45-pound dog gives a sense of the size of the bedrock boulders being eroded from the side of the Teanaway River. The previous floodplain is just visible at the top of the frame. Credit: Sarah Schanz/Indiana University Geologic time is supposed to be slow, and the most solid object should be bedrock. But…

Entomologists uncover Florida fire ant matriarchy

Credit: Andrew Davis Tucker/UGA In most colonies, ants work in service of a single reproductive queen, but that's not always the way ant societies function. Researchers at the University of Georgia have found colonies of tropical fire ants, native…

Scientists use eBird data to propose optimal bird conservation plan

This is a Canada warbler. Credit: Cameron Rognan/Cornell Lab of Ornithology A new paper published today in the journal Nature Communications shows a blueprint for conserving enough habitat to protect the populations of almost one-third of the warblers, orioles, tanagers, and other birds that migrate among the Americas throughout the year. For the research, an…

Scientists lead the way to produce tools for engineering biomolecules

This graphic depicts oppositely charged, synthetic proteins combine to form novel hierarchically assembled symmetrical structures toward biotemplated advanced materials. Credit: Courtesy of Autumn Kulaga, CCDC Army Research Laboratory Army scientists have discovered how to build novel synthetic biomolecule complexes that they believe are a critical step towards biotemplated advanced materials. Their work was recently featured…

Best in snow: New scientific device creates electricity from snowfall

Boot with device attached. Credit: Abdelsalam Ahmed UCLA researchers and colleagues have designed a new device that creates electricity from falling snow. The first of its kind, this device is inexpensive, small, thin and flexible like a sheet of plastic. "The device can work in remote areas because it provides its own power and does…

Meteoroid strikes eject precious water from moon

Artist's concept of the LADEE spacecraft (left) detecting water vapor from meteoroid impacts on the Moon (right). Credit: NASA/Goddard/Conceptual Image Lab Researchers from NASA and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, report that streams of meteoroids striking the Moon infuse the thin lunar atmosphere with a short-lived water vapor. The findings…

High-speed ‘electron camera’ films molecular movie in HD

This illustration shows snapshots of the light-triggered transition of the ring-shaped 1,3-cyclohexadiene (CHD) molecule (background) to its stretched-out 1,3,5-hexatriene (HT) form (foreground). The snapshots were taken with SLAC's high-speed "electron camera" - an instrument for ultrafast electron diffraction (UED).

New compound allows bacterial communication to be controlled by light

Irradiation setup to switch the photoswitchable modulator of bacterial communication from the trans-isomer to the more active cis-isomer. Credit: Dusan Kolarski, University of Groningen Scientists from the University of Groningen have succeeded in incorporating a light-controlled switch into a molecule used by bacteria for quorum sensing -- a process by which bacteria communicate and subsequently…

TESS finds its first Earth-sized planet

This is an artist's conception of HD 21749c, the first Earth-sized planet found by NASA's Transiting Exoplanets Survey Satellite (TESS), as well as its sibling, HD 21749b, a warm sub-Neptune-sized world.

To protect stem cells, plants have diverse genetic backup plans

When the maintenance of stem cells is disrupted, the consequences are often very visual. In the case of this tomato plant, the cells driving flower growth have over-proliferated, creating a disorganized mass of petals. Credit: Lippman Lab/CSHL, 2019 Despite evolution driving a wide variety of differences, many plants function the same way. Now a new…
