Droplet spread from humans doesn't always follow airflow

The World Health Organization has warned that aerosol transmission of COVID-19 is being underestimated. If aerosol spread is confirmed to be significant, as suspected, we will need to reconsider guidelines on social distancing, ventilation systems and shared spaces.

CERN experiments announce first indications of a rare Higgs boson process

At the 40th ICHEP conference, the ATLAS and CMS experiments announced new results which show that the Higgs boson decays into two muons. The muon is a heavier copy of the electron, one of the elementary particles that constitute the matter content of the Universe. While electrons are classified as a first-generation particle, muons belong to the second generation. The physics process of the Higgs boson decaying into muons is a rare phenomenon as only about one Higgs boson in 5000 decays into muons. These new results have pivotal importance for fundamental physics because they indicate for the first time that the Higgs boson interacts with second-generation elementary particles.

Casimir force used to control and manipulate objects

A collaboration between researchers from the University of Western Australia and the University of California Merced has provided a new way to measure tiny forces and use them to control objects.

Sulfur-containing polymer generates high refractive index and transparency

Researchers reported a novel technology enhancing the high transparency of refractive polymer film via a one-step vapor deposition process. The sulfur-containing polymer (SCP) film produced by Professor Sung Gap Im's research team at KAIST's Department of Chemical and Biomolecular Engineering has exhibited excellent environmental stability and chemical resistance, which is highly desirable for its application in long-term optical device applications. The high refractive index exceeding 1.9 while being fully transparent in the entire visible range will help expand the applications of optoelectronic devices.

Scientists propose a novel method for controlling fusion reactions

Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions—delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

Professor's milestone in nuclear physics seeks to understand the universe itself

A nuclear physics professor from Florida International University was among a team of researchers that proposed something so out of this world, colleagues first hesitated to accept it was possible.

Researchers explore the origins of stars rich in phosphorus

The journal Nature Communications has published the discovery of a new type of star that is very rich in phosphorus, which could help to explain the origin of phosphorous in our galaxy. This achievement has been made by astronomers of the Instituto de Astrofísica de Canarias (IAC) and researchers in computer science from the Centre for Research in Information and Communication Technology (CITIC) at the University of La Coruña (Galicia).

Surprisingly dense exoplanet challenges planet formation theories

New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet's existence is at odds with the predictions of leading planet formation theories.

Future energy systems need to be climate proof

Climate policy for future energy systems typically focus on the challenge to make them carbon neutral to avoid climate change. However, it will also be critically important to make them climate proof to ensure that they are resilient to future climate change. This is the key conclusion of a literature review published in Nature Energy, analyzing 220 peer-reviewed articles. Climate proofing of energy systems is becoming more important as energy systems are expected to become more sensitive to climate change.

Researchers shine light on roiling market for stolen debit and credit cards

Much of the world has switched to embedded anti-counterfeit EMV (Europay, MasterCard, Visa) chips in credit cards, but adoption in the U.S. lags. Therefore, a significant percentage of the U.S. population is vulnerable to theft by "skimming" and other means of stealing data from magnetic stripes during the transactional process, which is then used to produce counterfeit cards or to monetize data through other illicit activities.

Safeguarding the power supply in the event of a major outage

Germany's power supply is one of the most reliable in the world. Yet the growth in renewable energy has introduced a host of unpredictable factors into the power mix. The increasing number of irregular power sources can bring problems for grid stability. Moreover, in the event of a prolonged outage, there is the need to maintain the supply of power to critical infrastructure. In a groundbreaking concept, Fraunhofer research teams are seeking to combine digital twin technology with a fleet of autonomous electric vehicles for precisely this purpose.
