Spotlight Stories Headlines
🗞 TECHNOLOGY NEWS💻🔧🖥:
RESEARCHERS DEVELOP ULTRATHIN, SELF-POWERED E-HEALTH PATCHES THAT CAN MONITOR A USER’S PULSE AND BLOOD PRESSURE
Scientists at Osaka University, in cooperation with Joanneum Research (Weiz, Austria), have developed wireless health monitoring patches that use embedded piezoelectric nanogenerators to power themselves with harvested biomechanical energy. This work may lead to new autonomous health sensors as well as battery-free wearable electronic devices.
RETHINKING HYDROPOWER FOR ENERGY AND ENVIRONMENTAL SUSTAINABILITY
A California company, Natel Energy, is hard at work developing a low-head, low-impact hydropower approach that addresses one of the leading concerns of new deployment—impacts to natural stream flows.
HEAVY-DUTY VEHICLES AN IDEAL ENTRY INTO HYDROGEN FUEL CELL USE
Through a consortium of Department of Energy national laboratories, Oak Ridge National Laboratory scientists are applying their expertise to provide solutions that enable the commercialization of emission-free hydrogen fuel cell technology for heavy-duty vehicles, or HDV. As a viable alternative to internal combustion engines powered by gasoline, hydrogen fuel cells can provide sustainable, clean energy with a comparable user experience.
🗞 PHYSICS NEWS⚙♨:
RESEARCH PAVES WAY FOR IMPROVED LASERS, COMMUNICATIONS
New photonics research paves the way for improved lasers, high-speed computing and optical communications for the Army.
WITH NEW OPTICAL DEVICE, ENGINEERS CAN FINE TUNE THE COLOR OF LIGHT
Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow—red, orange, yellow, green, blue, indigo, violet.
QUANTUM STEERING FOR MORE PRECISE MEASUREMENTS
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles.
🗞 EARTH NEWS🌏:
CLIMATE-FRIENDLY MICROBES CHOMP DEAD PLANTS WITHOUT RELEASING HEAT-TRAPPING METHANE
The tree of life just got a little bigger: A team of scientists from the U.S. and China has identified an entirely new group of microbes quietly living in hot springs, geothermal systems and hydrothermal sediments around the world. The microbes appear to be playing an important role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane.
NEW STUDY PREDICTS HUMAN EXODUS IN BANGLADESH DUE TO SEA-LEVEL RISE
Rising sea levels and more powerful cyclonic storms, phenomena driven by the warming of oceans due to climate change, puts at immediate or potential risk an estimated 680 million people living in low-lying coastal zones (a number projected to reach more than one billion by 2050). In nations like Bangladesh these populations are already moving to escape sea-level rise.
‘LIKE A METRONOME’: STALAGMITE GROWTH FOUND TO BE SURPRISINGLY CONSTANT
To look inside a stalagmite is to look back in time tens of thousands of years to see how the Earth’s climate patterns have shaped the world we live in today.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
THE EFFECTS OF SOLAR FLARES ON EARTH’S MAGNETOSPHERE
Planet Earth is surrounded by a system of magnetic fields known as the magnetosphere. This vast, comet-shaped system deflects charged particles coming from the sun, shielding our planet from harmful particle radiation and preventing solar wind (i.e., a stream of charged particles released from the sun’s upper atmosphere) from eroding the atmosphere.
ASTEROID THAT HIT BOTSWANA IN 2018 LIKELY CAME FROM VESTA
An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science.
🗞 NANOTECHNOLOGY NEWS⛄☃:
CHEMISTS SHOW IONS’ STAGED RELEASE FROM GOLD-SILVER NANOPARTICLES COULD BE USEFUL PROPERTY
There’s gold in them thar nanoparticles, and there used to be a lot of silver, too. But much of the silver has leached away, and researchers want to know how.
3D MOTION TRACKING SYSTEM COULD STREAMLINE VISION FOR AUTONOMOUS TECH
A new real-time, 3D motion tracking system developed at the University of Michigan combines transparent light detectors with advanced neural network methods to create a system that could one day replace LiDAR and cameras in autonomous technologies.
