Good news, everyone!

Urinary tract infections (UTIs) are among the most common bacterial infections, with catheter-associated UTIs accounting for more than half of infections contracted in hospitals. When detected early and accurately, UTIs are treatable. Current diagnostic methods can be slow or inaccurate, creating a need for improved methods.

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked up by different telescopes that are at different locations, then reconstructing images using computational techniques.

One night in 2010, Mohit Gupta decided to try something before leaving the lab. Then a Ph.D. student at Carnegie Mellon University, Gupta was in the final days of an internship at a manufacturing company in Boston. He'd spent months developing a system that used cameras and light sources to create 3D images of small objects. "I wanted to stress test it, just for fun," said Gupta, who would begin his postdoctoral research at Columbia Engineering a few months later.

It will be business as usual for SpaceX when it tries to send up a rocket from the Space Coast Thursday night, but not so much for when the rocket comes back down.

More cases of colorectal cancer are detected at an early stage with screening. This is according to new research based on data from over 278,000 60-year-olds, who were randomly selected to undergo one of two interventions or no screening at all (usual care). The study, which is a collaboration between Uppsala University and Karolinska Institutet, has been published in Nature Medicine.

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a group of specialized cells, known as "germ cells," which will later form sperm and eggs, these inherited chemical instructions must be erased or reshuffled so development can begin again with a fresh blueprint in future generations.

New research shows that employees are far more likely to act in environmentally responsible ways when their leaders actively demonstrate green values in how they lead, not just what they say. The study, published in the Journal of Organizational Effectiveness: People and Performance, finds that leadership is the critical foundation of an authentic green workplace culture. Where leaders consistently prioritize environmental responsibility, employees respond with higher levels of voluntary green behavior, from reducing waste to conserving resources and supporting sustainability initiatives.

Research shows that metabolic surgery and GLP-1 medications are both effective therapies for treating obesity. Medications typically result in a 10% loss of body weight in a real-world setting, while surgery can achieve more dramatic results, up to 25% to 30%.

Approximately 10.5 million Americans have atrial fibrillation (AFib), a condition that causes an irregular, often too fast, heartbeat. AFib increases the risk of stroke four to five times more than normal because it can cause blood to pool in the atria, or upper chambers of the heart. This allows clots to form, which can travel to the brain and cause a stroke.

Stanford d.school's Jeremy Utley wants people to stop using AI. Instead, he wants them to work with it. "If you're 'using' AI, I know you're misusing it," said Utley, an adjunct professor at the Hasso Plattner Institute of Design (aka the "d.school"). Utley argues that people fall into two categories when it comes to AI: underperformers who treat it like a tool and outperformers who treat it like a teammate.

Led by Dr. Marco Funari, the project focused on developing a 3D model of a Grade I listed historic site, providing an accurate representation of the building's current condition to support effective management and preservation. The project addresses the United Nations Sustainable Development Goals (UN SDGs) SDG 9 and SDG 11.

On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a cosmic ray detector, was designed to measure the radiation environment in Earth orbit. Though its final transmission was in May 1958, it continued to revolve around Earth more than 58,000 times. As those looping orbits continued, NASA was busy building other groundbreaking instruments to observe and better understand Earth's systems.

Mitral regurgitation is the most prevalent valvular heart disease in humans. It's also common among dogs, especially older and smaller breed dogs. In both species, the mitral valve fails to close tightly enough to keep blood from flowing back into the left atrium as the heart is contracting. Untreated, it can lead to heart failure. Surgery is often needed to repair this issue in humans. For dogs, treatment has historically been less advanced, but veterinarians and animal researchers are taking cues from the human health world.

Cancer researchers are making strides in efforts to use genetic profiling to develop a more precise understanding of the response to treatment of acute myeloid leukemia (AML), a rare but aggressive blood cancer.

When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region of the electromagnetic spectrum. Infrared spectroscopy, which measures how light excites these vibrations, is often likened to listening to a molecule's voice.

When developing new drugs, one thing is particularly important: finding and producing the right molecules that can be used as active ingredients. The key elements of some drugs, such as penicillin, are small, tri- or quadripartite ring molecules. A team led by Prof Frank Glorius from the Institute of Organic Chemistry of the University of Münster (Germany) has now developed a method for efficiently converting readily available basic materials into such small, high-grade ring molecules. The product has a structure reminiscent of a line drawing of a house, hence its name "housane." The reaction is triggered by a photocatalyst that transfers light energy to the molecules to enable the conversion.

We all know the feeling: the mental clarity that comes after a good run or a heavy workout. Science backs this up, even showing that for non-severe depression, exercise can be just as effective as antidepressants or therapy. But there is a cruel irony at play: the symptoms of depression, such as low energy and lack of motivation, are often the very things that can stop people from moving.

Can fragments of tumor DNA in the blood predict whether chemotherapy will be effective? Researchers at the Princess Máxima Center investigated this question together with experts from Italy and Slovakia. They focused specifically on young adults with germ cell tumors for whom standard chemotherapy doesn't work well.

Language barriers contribute substantially to inequities in U.S. surgical care. Spanish-speaking patients are especially affected by communication challenges and inconsistent interpreter access during complex or time-sensitive encounters. A study led by Gezzer Ortega, MD, MPH, a physician investigator from the Center for Surgery and Public Health at Brigham and Women's Hospital, sought to understand how Spanish-speaking surgical patients perceive emerging interpreter technologies, specifically artificial intelligence (AI)-based interpretation and remote video interpretation (RVI), and how these modalities could be implemented in clinical practice.

In the realm of medical advancements, a universal vaccine that can protect against any pathogen has long been a Holy Grail—and about as elusive as a mythological vessel. But Stanford Medicine researchers and collaborators have taken an astonishing step forward in that quest, surprising even themselves.

The brain not only communicates through fast electrical impulses, it also relies on slower, more diffuse chemical signals that modulate our emotional and social states over time. A study led by the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University of Elche (UMH), has identified a key molecular mechanism that regulates the release of oxytocin within the brain.

A new study demonstrates that computer models of gut metabolism can predict which probiotics will successfully establish themselves in a person's gut and how different prebiotics affect production of health-promoting short-chain fatty acids. The findings are published in PLOS Biology by Sean Gibbons of the Institute for Systems Biology, US, and colleagues.

RMIT University researchers have developed a flexible nylon-film device that generates electricity from compression and keeps working even after being run over by a car multiple times, opening the door to self-powered sensors on our roads and other electronic devices. The paper is published in the journal Nature Communications.

An international research team has demonstrated how conventional radiative cooling coatings can be optimized to further reduce building surface temperatures, cutting energy consumption, while also improving fire safety.

Flexible electronics are often sold on a simple promise: bendable screens, lightweight solar cells or wearable devices that can bend and flex without breaking. But what does that "flexibility" actually look like at the molecular scale, and how does it affect performance? Researchers led by the University of Cambridge say they have taken a first step towards answering this question. Using ultra-sensitive atomic force microscopy—which analyzes materials by "feeling" them—the researchers were able to measure how stiff flexible semiconductor molecules are when packed together, down to the scale of just a few molecules.

Researchers at Columbia Engineering have developed a new gel electrolyte that both improves the lifetime and safety of anode-free lithium batteries, an emerging battery architecture that could dramatically boost energy density while simplifying manufacturing. Although such a design promises higher energy density and lower cost, the approach has long been plagued by short battery life and safety concerns caused by unstable lithium plating and parasitic reactions at the electrode-electrolyte interface.

It happens every day—a motorist heading across town checks a navigation app to see how long the trip will take, but they find no parking spots available when they reach their destination. By the time they finally park and walk to their destination, they're significantly later than they expected to be.

Researchers from the Department of Computer Science at Bar-Ilan University and from NVIDIA's AI research center in Israel have developed a new method that significantly improves how artificial intelligence models understand spatial instructions when generating images—without retraining or modifying the models themselves. Image-generation systems often struggle with simple prompts such as "a cat under the table" or "a chair to the right of the table," frequently placing objects incorrectly or ignoring spatial relationships altogether. The Bar-Ilan research team has introduced a creative solution that allows AI models to follow such instructions more accurately in real time.

Small, possibly portable, nuclear reactors that can't melt down are moving toward reality in the United States, with what may be the first two coming online or beginning construction this year.

Researchers at Kogakuin University have discovered that adding phosphorus (P2O5) to sodium-yttrium-silicate glasses significantly enhances their performance as solid electrolytes for next-generation sodium-ion batteries. This improvement arises from the formation of the high-performance Na5YSi4O12 crystal phase, which promotes high ionic conductivity and stability, making sodium-based batteries a safer and promising alternative to lithium-ion technologies. However, the effects of phosphorus on the glass structure and its location after crystallization had not been fully understood.

Researchers have developed a solar cell system that uses mirrors to concentrate solar energy. In addition to electricity, it produces heat for a plant that will capture carbon from industrial emissions. The solar cells in the large pilot plant are a full 5 meters high and consist of many mirrors that are angled toward the solar cells to concentrate sunlight. They make it possible to collect the sun's rays into concentrated solar energy, as well as heat that supports a plant designed to capture CO2.

The EU is expected to achieve climate neutrality by 2050. How far along is it? "At its core, we simply don't know. We have a good picture of the supply side—how quickly wind turbines are being erected, grids expanded, and storage capacity increased. But there are no official figures on how fast industry and firms are retrofitting, replacing their machinery, and electrifying their processes," says CSH President Stefan Thurner.

Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.

Combining wind turbines with wave, solar and tidal devices on shared platforms reduces construction costs, improves stability and generates more reliable power, according to researchers from the University of Surrey.
