Physicists pin down the pay off between speed and entropy

“You have to work harder to get the job done faster,” explains Gianmaria Falasco, a researcher at the University of Luxembourg as he sums up the results of his latest work with Massimiliano Esposito. This will come as no …

Nanoengineered biosensors for early disease detection

University of Queensland researchers have developed biosensors that use nanoengineered porous gold which more effectively detect early signs of disease, improving patient outcomes.

Four new open clusters detected in the Cygnus Cloud

By analyzing the data from ESA’s Gaia satellite, Chinese astronomers have discovered four new open clusters in the Cygnus Nebula Cloud. The newfound clusters, designated QC1 to QC 4, are located between 4,100 and 7,600 light-years …

Galactic bar paradox resolved in cosmic dance

New light has been shed on a mysterious and long-standing conundrum at the very heart of our galaxy. The new work offers a potential solution to the so-called “Galactic bar paradox,” whereby different observations produce …

Transparent near-infrared light-emitting diodes

NUS researchers have developed transparent, near-infrared-light-emitting diodes (LEDs) that could be integrated into the displays of smart watches, smart phones and augmented or virtual reality devices.

Detecting and responding to incidents with images

When a natural disaster occurs, on-the-ground emergency response teams act quickly to make life-saving decisions. Reducing the response time in such situations is critical to reduce damage impact and save lives. Helpful efforts …

Potential of achieving climate target with bioenergy is limited

Large-scale implementation of bioenergy with carbon capture and storage (BECCS) is often considered to be an important measure to reach the climate targets set out in the Paris Agreement. A new study from researchers at Radboud …

Scientists get atomistic picture of platinum catalyst degradation

Degradation of platinum, used as a key electrode material in the hydrogen economy, severely shortens the lifetime of electrochemical energy conversion devices, such as fuel cells. For the first time, scientists elucidated …

Blocking cellular communication stops SARS-CoV-2

In the transmission of signals within the cell which, for example, stimulate cell growth or trigger metabolic processes, phosphate groups play an important biochemical role. The phosphate groups are often attached to proteins …

Climate change and the challenge of community relocation

Climate change will profoundly affect how people move and where people live. Coastal communities, home to approximately 40% of the U.S. population, face the prospect of continuing sea level rise. Inland areas are not immune, …

A new generation of synchrotron

Inside the European Synchrotron Radiation Facility’s 844-meter-diameter storage ring, electrons traveling at almost the speed of light produce some of the brightest X-ray beams in the world. These X-rays can reveal the position …

How students learn from their mistakes

An fMRI-based study of error-monitoring shows that students who are focused on monitoring their own learning process, rather than on getting right answers, learn better over time.

Why COVID-19 infection curves behave so unexpectedly

With the first COVID-19 epidemic peak behind them, many countries explained the decrease of infection numbers through non-pharmaceutical interventions. Phrases like “social distancing” and “flatten the curve” have become …

Computers excel in chemistry class

Machine learning models can rapidly and accurately estimate key chemical parameters related to molecular reactivity.

What new research reveals about rude workplace emails

With the advent of the coronavirus pandemic and remote work on the rise, the sheer volume of email exchanges has skyrocketed. Electronic communication is efficient, but it’s also distant and detached, and often can be rude.

A colorful detector

Researchers at the University of Tsukuba have developed a new kind of color-shifting crystalline material that can be used to indicate the presence of water. The change in hue is dramatic enough to be gaged by the unaided …

High human population density negative for pollinators

Population density, and not the proportion of green spaces, has the biggest impact on species richness of pollinators in residential areas. This is the result of a study from Lund University in Sweden of gardens and residential …
