Good news, everyone!

Time-restricted eating has emerged as a popular dietary approach because it focuses on when people eat rather than strictly limiting calories. Instead of counting calories, individuals restrict their daily food intake to a defined time window. While this approach has been widely studied, most research has focused on whether time-restricted eating works, with less attention paid to how eating timing and eating duration interact.

Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature Photonics, the team, led by Ranjan Singh at the University of Notre Dame, say that with further refinements, the design could help underpin future sixth-generation (6G) wireless networks, allowing data to be shared at unprecedented speeds.

Rounds focused on critically ill pediatric patients at the greatest risk for developing health care–associated conditions (HACs) reduced the rate of specific HACs by nearly 50% at a Colorado hospital, according to a study published in Critical Care Nurse. After implementing a high-risk rounding process, Children's Hospital Colorado, Aurora, was able to decrease the mean rate of project-specific HACs in its pediatric intensive care unit (PICU) from 5.41 to 2.89 events per 1,000 patient days. The 48-bed PICU averages 3,500 admissions annually from across the seven states served by the hospital.

There is no known cure for Huntington's disease. A genetic mutation creates harmful proteins that accumulate and cause the disease's typical symptoms. A team from the Department of Human Genetics at Ruhr University Bochum, Germany, has now shown how targeted ubiquitin tagging at two positions in the mutated huntingtin protein affects its breakdown and distribution within the cell. This insight could provide a starting point for future therapies. The team in Bochum, led by Professor Hoa Huu Phuc Nguyen, worked closely with Israeli researcher Professor Aaron Ciechanover, who was awarded the Nobel Prize in Chemistry in 2004 for his work on the protein degradation system.

Selecting the healthiest embryo is one of the most important steps in in‑vitro fertilization (IVF), yet it remains one of the most uncertain. Roughly 15% of couples worldwide experience infertility, and IVF success rates often remain below 33%. A major challenge is that embryologists must choose a single embryo to implant, relying on what they can see under a microscope.

How do children learn to cooperate with others? A new cross-cultural study suggests that the answer depends less on universal rules and more on the social norms surrounding the child.

A research team at The Hong Kong University of Science and Technology (HKUST) has developed an innovative urban food waste management framework by analyzing food waste data from 29 large cities worldwide, including Hong Kong, Beijing, and New York. The study shows that in cities with higher food waste moisture loads, such as Hong Kong, grinding food waste and diverting it into the sewage system is more effective than relying solely on landfilling. This approach can reduce overall greenhouse gas emissions by about 47% and lower total waste-management costs by about 11%. The research provides a new, quantitative basis for shaping food waste management strategies in cities around the globe.

Utrecht University researchers Rodolfo Subert and Marjolein Dijkstra show in their latest study that complex three-dimensional networks in materials can emerge from nothing more than particle shape. In Nature Communications they describe how simple geometries, aided by entropy, can give rise to layers, networks and even spontaneous left- and right-handed twisting, which is a phenomenon previously linked mainly to highly complex molecules.

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today's sensors do not work optimally in humid environments—because where there is hydrogen, there is very often humidity. Now, researchers at Chalmers University of Technology, Sweden, are presenting a new sensor that is well suited to humid environments—and actually performs better the more humid it gets.

A University of Houston psychology professor is challenging the notion that dyslexia, or specific reading disorder, stems from a single faulty gene in the brain, suggesting instead that it is caused by an overall brain network vulnerability. The insight reshapes understanding of one of the world's most common learning disorders, which affects up to 20% of the world's population—nearly 780 million people who face lifelong challenges with reading.

Doing something romantic for Valentine's Day does not need to involve a heart-shaped box of chocolates, roses or an atypically expensive dinner, according to relationship experts.

Why did the rotisserie chicken cross the aisle—and end up in your shopping cart? Maybe you grabbed the container that was closest to you, or maybe you examined all of the chickens, checking dates and timestamps to see when they were cooked. Markets follow various display strategies for prepared foods, with many stores making older items more visible so they'll be sold before they spoil. However, a theoretical model created by an NJIT researcher suggests that customers prefer finding the freshest items at the front of the displays.

Researchers have analyzed the stepwise hydration of prolinol, a molecule widely used as a catalyst and as a building block in chemical synthesis. The study shows that just a few water molecules can completely change the preferred structure of prolinol. The research is published in the Journal of the American Chemical Society.

Students with disabilities account for almost 15% of the K-12 student population in the United States. Yet they are often underrepresented in charter schools, which are publicly funded schools open to all students. While there are discussions about what type of school environment best supports these students, it is important to take a closer look at the difference in learning environments.

GLP-1 drugs have ushered in a new era in weight loss.

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown that one such structure, known as i-DNA, not only forms in living cells but also acts as a regulatory bottleneck linked to cancer.

For decades, astronomers have been watching WOH G64, an enormous heavyweight star in the Large Magellanic Cloud, a galaxy visible with the naked eye from the Southern Hemisphere. This star is more than 1,500 times larger than the sun and emitting over 100,000 times more energy. For a long time, red supergiant WOH G64 looked like a star steadily reaching the end of its life, shedding material and swelling in size as it began to run out of fuel.
