SUPERSIZED WIND TURBINES GENERATE CLEAN ENERGY—AND SURPRISING PHYSICS

Twenty years ago, wind energy was mostly a niche industry that contributed less than 1% to the total electricity demand in the United States. Wind has since emerged as a serious contender in the race to develop clean, renewable energy sources that can sustain the grid and meet the ever-rising global energy demand. Last year, wind energy supplied 7% of domestic electricity demand, and across the country—both on and offshore—energy companies have been installing giant turbines that reach higher and wider than ever before.

TRACING THE FLOW OF CEREBROSPINAL FLUID

Swelling is one of the most dangerous and immediate consequences of a brain injury or stroke. Doctors have long known about the dangers of swelling, which has traditionally been blamed on ruptured blood vessels. New research suggests the brain’s other plumbing system, the one that circulates cerebrospinal fluid (CSF), may play an underappreciated role in both good health and response to injury.

UNDERSTANDING DANGEROUS DROPLET DYNAMICS

Researchers who study the physics of fluids are learning why certain situations increase the risk that droplets will transmit diseases like COVID-19.

RESTORATION OF DEGRADED GRASSLANDS CAN BENEFIT CLIMATE CHANGE MITIGATION AND KEY ECOSYSTEM SERVICES

New research has demonstrated how, in contrast to encroachment by the invasive alien tree species Prosopis julifora (known as Mathenge -in Kenya or Promi in Baringo), restoration of grasslands in tropical semi-arid regions can both mitigate the impacts of climate change and restore key benefits usually provided by healthy grasslands for pastoralists and agro-pastoralist communities.

STABILITY OF EARTH’S BIGGEST LUMP OF ICE AT RISK FROM WARMING OCEANS

The drastically increasing influence of humans on Earth’s climate causes a melting of polar ice sheets and therefore a rise in global sea levels. A team of international scientists led by the Institute of Earth Sciences at Heidelberg University and including the University of Southampton has now analyzed the response of the largest ice sheet on Earth—the East Antarctica Ice Sheet—to a warming climate.

CASCADING EVENTS LED TO 2018 KĪLAUEA VOLCANIC ERUPTION, PROVIDING CLUES FOR FORECASTING

The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai’i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai’i (UH) at Mānoa and U.S. Geological Survey (USGS).

In his paper uploaded to the arXiv preprint server, Caballero describes searching the Gaia database for possible sun-like stars that might host an exoplanet capable of supporting intelligent life.

NATIONAL SOLAR OBSERVATORY PREDICTS A LARGE SUNSPOT FOR THANKSGIVING

On November 18 scientists from the US National Science Foundation’s National Solar Observatory predicted the arrival of a large sunspot just in time for Thanksgiving. Using a special technique called helioseismology, the team has been ‘listening’ to changing sound waves from the Sun’s interior which beckon the arrival of a large sunspot. Recent changes in these sound waves pointed to the imminent appearance of new sunspots which we can now see from Earth near the eastern solar limb.

GEMINI NORTH OBSERVATIONS ENABLE BREAKTHROUGH IN CENTURIES-OLD EFFORT TO UNRAVEL ASTRONOMICAL MYSTERY

An international team of astronomers using Gemini North’s GNIRS instrument have discovered that CK Vulpeculae, first seen as a bright new star in 1670, is approximately five times farther away than previously thought. This makes the 1670 explosion of CK Vulpeculae much more energetic than previously estimated and puts it into a mysterious class of objects that are too bright to be members of the well-understood type of explosions known as novae, but too faint to be supernovae.

🗞 NANOTECHNOLOGY NEWS⛄☃:

DIRECT VISUALIZATION OF QUANTUM DOTS REVEALS SHAPE OF QUANTUM WAVE FUNCTION

Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.

SOUND WAVES POWER NEW ADVANCES IN DRUG DELIVERY AND SMART MATERIALS

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations.

ANIMAL-FREE METHOD PREDICTS NANOPARTICLE TOXICITY FOR SAFER INDUSTRIAL MATERIALS

Our lungs are exposed to a multitude of hazardous airborne particles on a daily basis. Nanoparticles, due to their small size, may reach the sensitive alveolar region of the human lung and trigger inflammation even after a single inhalation leading to severe diseases such as heart disease, brain damage and lung cancer for prolonged exposure. In manufacturing, toxic nanoparticles may be released into the environment during the production, processing, degradation or combustion of materials. Despite advances in models for nanotoxicology, currently neither in vitro nor in silico testing tools can reliably predict adverse outcomes or replace in vivo testing. In order to facilitate the introduction of safer materials into our lives, novel testing strategies are needed to predict the potential toxicity of industrial nanoparticles before and during the manufacturing process.

GOING BEYOND THE ANTI-LASER MAY ENABLE LONG-RANGE WIRELESS POWER TRANSFER

Ever since Nikola Tesla spewed electricity in all directions with his coil back in 1891, scientists have been thinking up ways to send electrical power through the air. The dream is to charge your phone or laptop, or maybe even a healthcare device such as a pacemaker, without the need for wires and plugs. The tricky bit is getting the electricity to find its intended target, and getting that target to absorb the electricity instead of just reflect it back into the air—all preferably without endangering anyone along the way.
