AN ON-SKIN DEVICE TO MEASURE SWEAT—RATE, LOSS AND TEMPERATURE—IN REAL-TIME
Monitoring sweat-related dynamics, such as sweat rate, cumulative sweat loss and sweat temperature over time could help doctors to diagnose thermoregulatory disorders and other illnesses related to heat stress. However, there are currently no devices that can accurately and continuously measure or estimate these parameters.
ENGINEERING STUDENT HELPS FEDERAL EXPERTS SOLVE A MESSY 3D PRINTING PROBLEM
Tomographic 3D printing is a revolutionary technology that uses light to create three-dimensional objects. A projector beams light at a rotating vial containing photocurable resin, and within seconds the desired shape forms inside the vial. The light projections needed to solidify specific 3D regions of the polymer are calculated using tomographic imaging concepts.
RESEARCHERS DEVELOP NEW METAL-FREE, RECYCLABLE POLYPEPTIDE BATTERY THAT DEGRADES ON DEMAND
The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.
? PHYSICS NEWS⚙♨:
RESEARCHERS PRODUCE LASER PULSES WITH RECORD-BREAKING INTENSITY
Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It took more than a decade to reach this laser intensity, which is ten times that reported by a team at the University of Michigan in 2004. These ultrahigh intensity light pulses will enable exploration of complex interactions between light and matter in ways not possible before.
TEAM DIRECTS AND MEASURES QUANTUM DRUM DUET
Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have “entangled” two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.
PHYSICISTS FIND A NOVEL WAY TO SWITCH ANTIFERROMAGNETISM ON AND OFF
When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of “bits” to represent and encode that image. Most transistors today are made from silicon, an element that scientists have managed to switch at ever-smaller scales, enabling billions of bits, and therefore large libraries of images and other files, to be packed onto a single memory chip.
? EARTH NEWS?:
ICE CORE CHEMISTRY STUDY EXPANDS INSIGHT INTO SEA ICE VARIABILITY IN SOUTHERN HEMISPHERE
Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a University of Maine-led study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend.
USING ENVIRONMENTAL MICROBES TO REMOVE URANIUM FROM GROUNDWATER
Uranium contamination of soils and groundwater in the United States represents a significant health risk and will require multiple remediation approaches.
A NEW METHOD TO TRIGGER RAIN WHERE WATER IS SCARCE
A new method to trigger rain in places where water is scarce is being tested in the United Arab Emirates using unmanned drones that were designed and manufactured at the University of Bath. The drones carry an electric charge that is released into a cloud, giving cloud droplets the jolt they need to clump together and fall as rain.
? ASTRONOMY & SPACE NEWS??:
THE NATURAL BRIGHTNESS OF THE NIGHT SKY
A recent study analyzes data collected at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete reference method to measure the natural brightness of the night sky using low-cost photometers.
PHYSICISTS DESCRIBE NEW TYPE OF AURORA
For millennia, humans in the high latitudes have been enthralled by auroras—the northern and southern lights. Yet even after all that time, it appears the ethereal, dancing ribbons of light above Earth still hold some secrets.
VOLCANOES ON MARS COULD BE ACTIVE, RAISING POSSIBILITY OF RECENT HABITABLE CONDITIONS
Evidence of recent volcanic activity on Mars shows that eruptions could have taken place within the past 50,000 years, a paper by Planetary Science Institute Research Scientist David Horvath says.

FIRST NANOSCALE LOOK AT A REACTION THAT LIMITS THE EFFICIENCY OF GENERATING CLEAN HYDROGEN FUEL
Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.
TOWARD 2D MEMORY TECHNOLOGY BY MAGNETIC GRAPHENE
In spintronics, the magnetic moment of electrons (spin) is used to transfer and manipulate information. An ultra-compact 2D spin-logic circuitry could be built from 2D materials that can transport the spin information over long distances and also provide strong spin-polarization of charge current. Experiments by physicists at the University of Groningen (The Netherlands) and Colombia University (U.S.) suggest that magnetic graphene can be the ultimate choice for these 2D spin-logic devices as it efficiently converts charge to spin current and can transfer this strong spin-polarization over long distances. This discovery was published on 6 May in Nature Nanotechnology.
TEAM USES LASER-INDUCED GRAPHENE PROCESS TO CREATE MICRON-SCALE PATTERNS IN PHOTORESIST
A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.
