A recent article in the ACS Sustainable Chemistry & Engineering journal reported that used coffee pods’ plastic can be recycled to create filament for 3D printers. The solution was successfully tested by research groups in Brazil at the Federal University of São Carlos (USFCar) and the State University of Campinas (UNICAMP) and in the UK

With the recent increase in extreme weather events both in New Zealand and globally, a new study published in Nature Geoscience aims to improve the prediction of heavy rainfall and provide earlier warnings to the public. Cameron McErlich, a Ph.D. student at the University of Canterbury, used models and satellite observations to examine daily rainfall.
Scientists from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences, leading an international team, have discovered aerosols from the Hunga Tonga eruption in the stratospheric westerlies of the Northern Hemisphere for the first time. The discovery, published in Science Bulletin, will help scientists to simulate the physical and chemical processes in
Researchers from Germany and the United States have discovered that terahertz (THz) light pulses can be used to stabilize ferromagnetism in a crystal at temperatures more than three times its usual transition temperature. This breakthrough could revolutionize processing speeds and efficiency. Details of the Study The team used pulses that were hundreds of femtoseconds long,
Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have developed a new technique to measure the masses of key nuclei with high precision. Using this method, they have studied X-ray bursts on the surface of a neutron star, which has provided new insights into the properties of these
Nightmares are a common problem that affects many people. Not only do they disturb sleep, but they are also linked to other health issues such as anxiety and poor-quality sleep. Researchers have been investigating ways to help reduce the frequency and severity of nightmares, and a recent study suggests that non-invasive techniques can help manipulate
As the International Space Station (ISS) approaches the end of its service, China and India are planning to deploy their own space stations, and NASA has contracted with three aerospace companies to design commercial space stations. Now, Airbus has proposed its own Multi-Purpose Orbital Module (MPOP) called the Airbus LOOP, a modular space segment for
Germany’s Economy Minister, Robert Habeck, has presented a plan to cap the price of electricity used by energy-intensive industries. The move aims to insulate the sector against sharp cost increases. However, the proposal has already sparked criticism. The cap would be set at €0.06 ($0.07) per gigawatt-hour (GWh) and would apply until 2030. At least
Glioblastoma is a malignant brain tumor known for its aggressiveness and difficulty to treat. However, a new hydrogel treatment has shown promising results in eliminating glioblastoma tumors in mice. The Hydrogel Treatment The hydrogel treatment uses paclitaxel, a chemotherapy drug, to create nano-sized filaments for insertion into the brain. The hydrogel covers the cancer cavity
Anomaly detection is a valuable tool in distinguishing normal data from abnormal data. It is achieved by assigning anomaly scores to each instance, which are then ranked and evaluated. However, using a static unsupervised streaming anomaly detector can be difficult to dynamically adjust anomaly score calculation. To overcome this, a research team led by Prof.
Researchers at North Carolina State University (NCSU) have discovered that senior dogs with cognitive decline experience disruptions similar to those found in people with Alzheimer’s disease. This study suggests that dogs could provide a good model for research on Alzheimer’s. The Study The researchers recorded the brain waves of 28 senior dogs, some with cognitive
The Moon is not the only object orbiting Earth; there are a small number of quasi-satellites that do as well. Kamo’oalewa is a near-Earth asteroid that was discovered in 2016, and it is one of these quasi-satellites. Its orbit changes over time, but it always stays near Earth. It reflects light the same way the
Artificial intelligence (AI) has been causing unease among Hollywood writers, with chatbots that write or rewrite scripts being one of the key concerns. The Writers Guild of America is currently striking for better pay, but AI is looming as a rising anxiety. AI-Powered Screenwriting AI chatbots could potentially be used to create a rough first
In March 2023, a group of researchers and tech leaders, including Elon Musk and Steve Wozniak, published an open letter calling for a pause in the artificial intelligence (AI) race. They recommended that labs halt the training of technologies stronger than OpenAI’s GPT-4, the most sophisticated language-generating AI system, for at least six months. While
Los Alamos scientists have achieved light amplification using electrically driven devices based on solution-cast semiconductor nanocrystals. These tiny specs of semiconductor matter are made through chemical synthesis, also known as colloidal quantum dots. This breakthrough, reported in the journal Nature, opens the door to a completely new class of electrically pumped lasing devices. These laser
