Making catalysts to convert waste carbon dioxide into useful industrial products has been expensive and complicated – until now. UNSW engineers show it’s as easy as playing with Lego.
A nifty move with nitrogen has brought the world one step closer to creating a range of useful products — from dyes to pharmaceuticals — out of thin air.
In August 2024, we published the next phase of our work in Science. Our research proposes a solution to one of the most difficult challenges in computational quantum chemistry: understanding how molecules transition to and from excited states when stimulated.
The new device can continuously sense levels of virtually any protein or molecule in the blood. The researchers say it could be transformative for disease detection, patient monitoring and biomedical research.
A mishap during an experiment led UNSW quantum computing researchers to crack a mystery that had stood since 1961.
When most people think about pi, they associate the mathematical constant with arcs and circles. Mathematicians, however, are accustomed to seeing it in a variety of fields. But two University physicists were still surprised to find it lurking in a quantum mechanics formula for the energy states of the hydrogen atom.
Researchers at EPFL are assessing Switzerland’s solar power potential. Their results show that photovoltaic panels could be installed on more than half of the country’s 9.6 million rooftops. The resulting power would meet more than 40% of Swiss electricity demand.
Many restaurants, theatres and offices are using infrared thermometers to get the country back to work. Multiple companies are advertising these as a way to ‘reassure’ employers and employees. In China, security guards have even been given infra-red spectacles in order to detect people with fever. But where’s the…
New brain networks come ‘online’ during adolescence, allowing teenagers to develop more complex adult social skills, but potentially putting them at increased risk of mental illness, according to new research published in the Proceedings of the National Academy of Sciences (PNAS).
New antiviral materials made from sugar have been developed by researchers from the University of Manchester, the University of Geneva and the EPFL in Lausanne. They can destroy viruses on contact and may help in the fight against viral outbreaks. Although at an early stage of development, the broad-spectrum activity…
AUSTIN, Texas — For decades, researchers have looked for ways to eliminate cobalt from the high-energy batteries that power electronic devices, due to its
Researchers at EPFL have developed a new, high-precision method for 3D-printing small, soft objects. The process, which takes less than 30 seconds from start to finish, has potential applications in a wide range of fields, including 3D bioprinting.
Stanford researchers have determined that average human body temperature in the United States has decreased since the 1800s.
Tracking brainwave patterns and symptoms in patients with depression, researchers used artificial intelligence to predict best treatment options.
The new saliva collection method, which RUCDR developed in partnership with Spectrum Solutions and Accurate Diagnostic Labs, will allow for broader population screening than the current method of nose and throat swabs.
The coronavirus epidemic started one month earlier than is commonly reported and has yet to be brought under control, a new disease-transmission model created by University of Toronto researchers suggests. Using open access data that are updated daily, the model replicates epidemiological scenarios and allows…
How much plastic ends up in the ocean? Where does it come from?
Climeworks has signed groundbreaking agreements with Carbfix and ON Power to lay the foundation for a new plant that will significantly scale-up carbon...
MIT Professor Christopher Voigt and his team are working to transform cereal crops so they are able to fix their own nitrogen. The research has been funded by the Abdul Latif Jameel Water and Food Systems Lab (J-WAFS).
Being able to feel empathy and to take in the other person's perspective – these are two abilities through which we understand what is going on in the other person's mind. Although both terms are in constant circulation, it is still unclear what exactly they describe and constitute. Scientists at the Max Planck…
Venus hosts brutal conditions today, but the planet may have once been more hospitable to life.
The history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, Cornell researchers have discovered a possible third type: g-wave.
A new study from Penn State tracked excess influenza-like illness data from the Centers for Disease Control and Prevention to estimate that the number of early COVID-19 cases in the U.S. may have been more than 80 times greater and doubled nearly twice as fast as originally believed.
