To kill a quasiparticle: A quantum whodunit Posted: 28 Sep 2020 06:37 AM PDT Quasiparticles die young, lasting far, far less than a second. Why? A new Monash University study finds a culprit beyond the usual suspect (decay into lower energy states). Identification of the new villain--many-body dephasing--may be key to controlling quantum effects such as superconductivity and superfluidity.

First study with CHEOPS data describes one of the most extreme planets in the universe Posted: 28 Sep 2020 06:05 AM PDT CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b - one of the most extreme planets known.

First measurements of radiation levels on the moon Posted: 26 Sep 2020 11:52 AM PDT In the coming years and decades, various nations want to explore the moon, and plan to send astronauts there again for this purpose. But on our inhospitable satellite, space radiation poses a significant risk. Scientists report for the first time on time-resolved measurements of the radiation on the moon. The measurements show an equivalent dose rate of about 60 microsieverts per hour. In comparison, on a long-haul flight from Frankfurt to New York, it is about 5 to 10 times lower, and on the ground well over 200 times lower.

Study reveals design flaws of chatbot-based symptom-checker apps Posted: 26 Sep 2020 11:52 AM PDT Millions of people turn to their mobile devices when seeking medical advice. They're able to share their symptoms and receive potential diagnoses through chatbot-based symptom-checker (CSC) apps. But how do these apps compare to a trip to the doctor's office? Not well, according to a new study.

Researchers help develop sustainable polymers Posted: 26 Sep 2020 11:51 AM PDT Researchers have made new discoveries on the effects of temperature on sustainable polymers. Their findings may help the industry to produce plastics that are better for the environment.

Physicists develop a method to improve gravitational wave detector sensitivity Posted: 25 Sep 2020 08:36 AM PDT Gravitational wave detectors opened a new window to the universe by measuring the ripples in spacetime produced by colliding black holes and neutron stars, but they are ultimately limited by quantum fluctuations induced by light reflecting off of mirrors. Researchers have conducted a new experiment to explore a way to cancel this quantum backaction and improve detector sensitivity.

3D camera quickly merges depth, spectral data Posted: 25 Sep 2020 08:36 AM PDT The Hyperspectral Stripe Projector captures spectroscopic and 3D imaging data for applications like machine vision, crop monitoring, self-driving cars and corrosion detection.

Lending color to dead cells -- A novel natural dye for screening cell viability Posted: 25 Sep 2020 08:36 AM PDT Synthetic dyes are commonly used to assess the toxicity of chemical compounds in cell cultures. However, these dyes damage cells, rendering the cultures useless for long-term experiments. Recently, scientists discovered that a natural food pigment can replace synthetic dyes in cell viability assays for three widely varied types of cells -- and performs better. Their approach is also environment-friendly and inexpensive, and opens up possibilities in a range of fields including drug discovery.

Tracking shape changes in Amazon fish after major river is dammed Posted: 25 Sep 2020 08:36 AM PDT Biologists compared museum collections of cichlid fishes collected before a dam was closed in 1984 on the Tocantins River in the Amazon and contemporary specimens taken from the Tucuruí Reservoir by fishermen 34 years later.

Machine learning takes on synthetic biology: algorithms can bioengineer cells for you Posted: 25 Sep 2020 08:34 AM PDT Scientists have developed a new tool that adapts machine learning algorithms to the needs of synthetic biology to guide development systematically. The innovation means scientists will not have to spend years developing a meticulous understanding of each part of a cell and what it does in order to manipulate it.

A clearer view of what makes glass rigid Posted: 25 Sep 2020 08:34 AM PDT Scientists used computer simulations to better understand the mechanical transition in glassy materials.

Magnetic 'T-Budbots' made from tea plants kill and clean biofilm Posted: 23 Sep 2020 09:47 AM PDT Biofilms -- microbial communities that form slimy layers on surfaces -- are difficult to treat and remove, often because the microbes release molecules that block the entry of antibiotics and other therapies.
