When Solids and Liquids Meet: In Nanoscale Detail
When Solids and Liquids Meet: In Nanoscale Detail
Infrared technique at Berkeley Lab's Advanced Light Source probes active chemistry at the solid-liquid interface How a liquid interacts with the surface of a solid is important in batteries and fuel cells, chemical production, corrosion phenomena, and many biological processes. To better understand this solid-liquid interface, researchers at Berkeley Lab developed a platform to explore these interactions under real conditions ("in situ") at the nanoscale using a technique that combines infrared light with an atomic force microscopy (AFM) probe.

Automated technique helps identify cancer cell metabolism inhibitors
FINDINGS UCLA Jonsson Comprehensive Cancer Center researchers have developed a new automated method for testing hundreds of molecules at a time to find out which ones block cancer cells from consuming glucose — the sugars they need to spread and grow. Using robotics, the researchers tested 3,555 compounds on non-small-cell lung cancer cells.

Underwater Telecom Cables Make Superb Seismic Network
Underwater Telecom Cables Make Superb Seismic Network
Adapted from a news release by UC Berkeley : Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath the ocean surface. In a recent paper in the journal Science , researchers from UC Berkeley, Lawrence Berkeley National Laboratory (Berkeley Lab), Monterey Bay Aquarium Research Institute (MBARI) , and Rice University describe an experiment that turned 20 kilometers of undersea fiber-optic cable into the equivalent of 10,000 seismic stations along the ocean floor.

A Matchmaker for Microbiomes
New tool will enable important insights into the microbial communities in the environment and inside our bodies Microbiomes play essential roles in the natural processes that keep the planet and our bodies healthy, so it's not surprising that scientists' investigations into these diverse microbial communities are leading to advances in medicine, sustainable agriculture, cheap water purification methods, and environmental clean-up technology, just to name a few.

New Software Aims To Make Science More Replicable
Every field in science and engineering employs highly specialized equipment: surface area analyzers, nanosizers, recording membrane osmometers. This equipment is often incredibly specific, designed for just a single function, but it's essential for performing accurate, replicable research. And without the ability to replicate the research of other scientists, the validity of science itself falls apart.

Many pregnancies are shorter as climate change causes more 90-degree days
A UCLA study suggests that climate change is causing many women to have shorter pregnancies than they would normally, which could pose risks for infant health and child development. According to research published today , birth rates were 5% higher on days when the temperature exceeded 90 degrees Fahrenheit.

Big Data makes intensive care better
Big Data makes intensive care better
Patient safety in intensive care units could be significantly improved if false alarms could be greatly reduced and critical complications such as epileptic seizures could be predicted. This is where the "ICU Cockpit" project of the National Research Programme "Big Data" (NRP 75) comes in: The large amounts of data from intensive care medicine will be used to develop procedures for early warning systems and therapeutic recommendations.

Improved health check for running waters
If one turns a stone over in a river or stream, it swarms with tiny animals: caddisflies, water beetles, freshwater shrimp, and snails. The invertebrates living on the beds of water bodies that can be seen with the naked eye, called macroinvertebrates, are rather unimposing, but for science and the protection of surface waters they are of great importance.

Placebo use among Australian GPs surprisingly high
Most Australian GPs have used a placebo in practice at least once, with active placebos (active treatments used primarily to generate positive expectations) more commonly used than inert placebos, according to a new study in Psychology. Placebo use by GPs high International studies indicate that placebo use by general practitioners (GPs) is remarkably high, but until now usage in Australia was unknown.

What's driving erosion worldwide?
What’s driving erosion worldwide?
ETH Zurich researchers are reexamining the causes of soil erosion around the world - and have found that countries themselves have a surprisingly strong influence on their soil. This country effect was previously undetected. Soil erosion is a global problem that threatens food security and the functioning of ecosystems.

Annual Title IX/Sexual Harassment Report released
Today Stanford University released its third annual Title IX/Sexual Harassment Report , which outlines the ways in which the university responded to reported concerns of sexual harassment, sexual violence and gender discrimination on campus and in all programs and activities connected to Stanford. The report includes information about reports of prohibited sexual conduct involving students, faculty and staff during the period from Sept.

CMU, UPMC researchers use machine learning algorithms to develop a risk score used to predict tachycardia episodes Artur Dubrawski is not a critical care physician, but his best friend is. Dubrawski, a research professor in Carnegie Mellon University's Robotics Institute , loves talking about disease symptoms with Michael Pinsky, a professor of critical care medicine, cardiovascular disease, bioengineering and more at the University of Pittsburgh Medical Center.

Controlling the optical properties of solids with acoustic waves
Controlling the optical properties of solids with acoustic waves
Physicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors. One of the main challenges in materials science research is to achieve high tunability of the optical properties of semiconductors at room temperature.

Opinion: How the technology behind deepfakes can benefit all of society
Professor Geraint Rees, Pro-Vice-Provost of Artificial Intelligence at UCL, writes that AI can and must be used for good, to complement and augment human endeavour rather than replace it. Recent advances in deepfake video technology have led to a rapid increase of such videos in the public domain in the past year.

Sounds of the past give new hope for coral reef restoration
Sounds of the past give new hope for coral reef restoration
An international team of scientists from the UK's Universities of Exeter and Bristol, and Australia's James Cook University and Australian Institute of Marine Science, say this "acoustic enrichment" could be a valuable tool in helping to restore damaged coral reefs. Working on Australia's recently devastated Great Barrier Reef, the scientists placed underwater loudspeakers playing healthy reef recordings in patches of dead coral and found twice as many fish arrived - and stayed - compared to equivalent patches where no sound was played.

Underwater telecom cables make superb seismic network
The oceans are criss-crossed by telecommunications cables, as illustrated by this graphic predicting the fiber-optic cables that will be operational by 2021, many of them (yellow) owned by private companies like Google and Microsoft. These cables could serve a dual purpose as seismic stations to monitor earthquakes and fault systems over the 70% of Earth covered by water.

Death risk up to 12 times higher for mothers with prenatal opioid use
Approximately one in 20 mothers whose babies are born with neonatal abstinence syndrome (NAS) died within 10 years of delivery in both England and Canada, according to a new study from researchers at UCL and ICES and The Hospital for Sick Children (SickKids) in Canada Neonatal abstinence syndrome (also called NAS) is a group of symptoms experienced by babies from withdrawal from certain drugs (predominantly opioids) that they are exposed to in the womb before birth.
