There is a supermassive black hole at the center of our galaxy, and it's not alone. There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually spiral ever closer together. These gravitational waves are too faint for us to detect at the moment, but future observatories will be able to observe them. This poses an interesting astronomical challenge.

A new technique to extract tiny cellulose strands from cow dung and turn them into manufacturing-grade cellulose, currently used to make everything from surgical masks to food packaging, has been developed.

Researchers have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual brain cells are affected, and how cells work together. The pipette could also be used for treatments.

Groundbreaking device instantly detects dangerous street drugs, offering hope for harm reduction A portable device that instantly detects illicit street drugs at very low concentrations, thereby highlighting the risks they pose. The device has the potential to address the growing global problem of people unknowingly taking drugs that have been mixed with undeclared substances, including synthetic opioids such as fentanyl and nitazenes.

Influenza viruses are among the most likely triggers of future pandemics. A research team has developed a method that can be used to study the interaction of viruses with host cells in unprecedented detail. With the help of their new development, they have also analyzed how novel influenza viruses use alternative receptors to enter target cells.

Two new advanced predictive algorithms use information about a person's health conditions and simple blood tests to accurately predict a patient's chances of having a currently undiagnosed cancer, including hard to diagnose liver and oral cancers. The new models could revolutionize how cancer is detected in primary care, and make it easier for patients to get treatment at much earlier stages.

As fast fashion continues to fill wardrobes and landfills at a staggering pace, new research suggests that the future of fashion might lie not in fabric, but in pixels.

Surgical face masks help prevent the spread of airborne pathogens and therefore were ubiquitous during the COVID-19 pandemic. Now, a modified mask could also protect a wearer by detecting health conditions, including chronic kidney disease. Researchers incorporated a specialized breath sensor within the fabric of a face mask to detect metabolites associated with the disease. In initial tests, the sensor correctly identified people with the condition most of the time.

Magnetar flares, colossal cosmic explosions, may be directly responsible for the creation and distribution of heavy elements across the universe, suggests a new study.

Researchers have outlined a bold new roadmap for harnessing heterogeneous catalysis to destroy per- and polyfluoroalkyl substances (PFAS), the so-called 'forever chemicals' that have contaminated water supplies worldwide.

National Football League (NFL) players may be more likely to sustain a specific type of knee injury if they have a shorter period of rest between games.

Physicists captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the 'free-range' particles that until now were predicted but never directly observed.

Engineers have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled. The water-from-air device remained effective across a broad range of humidity levels (30 -- 90%) and temperatures (5 -- 55 degrees Celsius).

Scientists have developed a lactation pad equipped with sensing technology that allows parents of newborns to monitor breast milk in real time. The device is capable of ensuring that breast milk contains safe levels of the painkiller acetaminophen, which is often prescribed after childbirth and can be transferred to breastfeeding infants.

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this complicated network requires a precise look into how these nerve cells are arranged and connected. A new method makes use of off-the-shelf light microscopes, hydrogel and deep learning.

An artificial intelligence (AI) model improved outcomes in hospitalized patients by quadrupling the rate of detection and treatment of delirium. The model identifies patients at high risk for delirium and alerts a specially-trained team to assess the patient and create a treatment plan, if needed.
