A soft layer of white snow blankets the grounds of the Chicago Botanic Garden. The air is chilly, the sky gray.

Just four months ago, Timor-Leste formally became a member of the Association of Southeast Asian States (ASEAN). This week, the tiny country took an unprecedented step: its judicial authorities appointed a prosecutor to examine the Myanmar military's responsibility for war crimes and crimes against humanity. It's believed to be the first time an ASEAN state has taken such an action against another member.

With the departure of the research vessel Polarstern from Punta Arenas (Chile) scheduled for this weekend, the "Summer Weddell Sea Outflow Study" (SWOS) international expedition will commence. Up to early April, a multidisciplinary international research team will investigate the northwestern region of the Weddell Sea—an area of central importance for the global climate and ocean system, but one that can only be explored on site by research icebreakers such as Polarstern due to challenging sea ice conditions.

Their study is published in Scientific Reports.

Two-dimensional (2D) materials, in general, allow the realization of unique quantum phenomena unattainable in the common three-dimensional (3D) world. A prime example is graphene. Transition metal dichalcogenides (TMDs) have a similar structure. Both can be stacked to form van der Waals heterostructures or can be exfoliated into single layers. But TMDs have an extra variety of excellent properties, including strong spin-orbit coupling and superconductivity.

American women now have the option of screening for cervical cancer at home, using newly approved self-collection tools. While experts hope this will increase uptake in the under-screened population, a first-of-its kind study by researchers from The University of Texas MD Anderson Cancer Center found the majority (60.8%) still prefer to see a medical professional in-clinic.

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is quantum key distribution (QKD), a secure, quantum-based method in which eavesdropping attempts disrupt the quantum state, making unauthorized interception immediately detectable.

Engineers at Washington University in St. Louis are working on this challenge, finding ways to stabilize ubiquitous iron components for use in fuel cells to replace the expensive platinum metals, which would make hydrogen fuel-cell vehicles more affordable.

Researchers in Australia have unveiled the largest quantum simulation platform built to date, opening a new route to exploring the complex behavior of quantum materials at unprecedented scales.

Research led by the University of East Anglia (UEA) sheds new light on how mountain birds adapt to changes in climate. Scientists know that species diversity changes as you go up a mountain, but it is not clearly understood why this is the case. One theory is that it is mostly because of long-term evolution, and the climate niches species have adapted to over millions of years. Another—the "energy efficiency" hypothesis—suggests it is about how species today manage their energy budgets and compete for available resources that vary in space and time.

The onset and aggressiveness of cancer are related to the abnormal behavior of certain genes, known as oncogenes. The best-known of these alterations is mutation, but it is not the only one. Sometimes, within a cell, a very high number of copies of the oncogene appear—tens or even hundreds. This amplification of oncogenes occurs in a significant proportion of solid tumors and may make the tumor more aggressive and prevent the body's defenses from detecting it, contributing to the development of resistance to treatments.

A team led by researchers at Baylor College of Medicine and the Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital has uncovered a chain of events that connects genetic alterations, disruptions in lipid metabolism and the manifestation of Parkinson's disease in patients. The findings, published in the journal Brain, bring forward the possibility of identifying people at risk before symptoms appear and developing strategies to treat the disease rather than manage the symptoms.

In recent years, cancer researchers have made major breakthroughs by using the body's immune system to fight cancer. One of the most promising approaches, known as immune checkpoint blockade, works by releasing molecular "brakes" on T cells. This allows them to better recognize and attack cancer cells. While these therapies can be very effective for some patients, many solid tumors, including most forms of breast cancer, remain largely unaffected. Cancer Center at Illinois (CCIL) Program Co-leader Erik Nelson and his research group are working to understand why these treatments fail.

Wistar scientists have combined a promising cancer therapy with a molecule that targets tumors to treat cancer more effectively. The new approach could be a way to deliver treatment directly to tumors at higher doses, while reducing side effects in healthy tissue. The research is published in the journal Molecular Cancer Therapeutics.

A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the microscopic mechanisms by which diamond surfaces affect the quantum coherence of nitrogen-vacancy (NV) centers—defects in diamond that underpin some of today's most sensitive quantum sensors. The study has appeared in Physical Review Materials and was selected to be an Editors' Suggestion paper.

Glioblastoma is the most prevalent and aggressive brain tumor. It proliferates very rapidly, is highly invasive, and there is currently no treatment capable of halting its progression or curing it, which means life expectancy after diagnosis is very short. The standard procedure involves surgical resection of the tumor followed by radiotherapy and chemotherapy, but even with this aggressive treatment, recurrences are very common, often within a year.

Deep brain stimulation (DBS) improves motor symptoms of Parkinson's disease by modulating a specific brain network that is mainly active in the fast beta frequency range (20 to 35 Hz). This conclusion was reached by an interdisciplinary team of neuroscientists and clinicians from the University Hospitals of Cologne and Düsseldorf, Harvard Medical School and Charité Berlin. The study "The Deep Brain Stimulation Response Network in Parkinson's Disease Operates in the High Beta Band" in the journal Brain is the first to bridge the gap between two ways of analyzing DBS response that were previously widely separate: electrophysiology and brain imaging.

Oxygen is a vital and constant presence on Earth today. But that hasn't always been the case. It wasn't until around 2.3 billion years ago that oxygen became a permanent fixture in the atmosphere, during a pivotal period known as the Great Oxidation Event (GOE), which set the evolutionary course for oxygen-breathing life as we know it today. A new study by MIT researchers suggests some early forms of life may have evolved the ability to use oxygen hundreds of millions of years before the GOE. The findings may represent some of the earliest evidence of aerobic respiration on Earth.

Cancer is one of the leading causes of death worldwide, marked by the uncontrolled growth of abnormal cells. What makes it more dangerous is the ability of cancer cells to move quickly through the body, allowing them to invade surrounding tissues. While this behavior is well known, the mechanism behind this rapid spread remains unclear. Researchers from Kyushu University set out to fill this gap and unveiled a new physical process that helps cancer cells move rapidly throughout the body.

A team of archaeologists from the Universitat Jaume I, the University of Barcelona, and the Catalan Institution for Research and Advanced Studies (ICREA) has developed a new methodology that allows for a much more detailed, precise, and objective analysis of Late Paleolithic portable art pieces. Thanks to this study, the research team was able to review several previously published pieces from Matutano Cave (Vilafamés), a reference site in the Iberian Mediterranean, with greater accuracy and demonstrate that some of the marks previously interpreted as artistic motifs are not anthropic engravings but natural surface reliefs.

A UT San Antonio-led international research team has identified chitin, the primary organic component of modern crab shells and insect exoskeletons, in trilobite fossils more than 500 million years old, marking the first confirmed detection of the molecule in this extinct group.

For decades, scientists assumed that order drives efficiency. Yet in the bustling machinery of mitochondria—the organelles that crank out adenosine triphosphate (ATP), the universal "energy currency" of cells—one of the most enigmatic components is a protein that appears anything but orderly.

In the U.S., one in eight women will get breast cancer in their lifetime, and about half of them will have mastectomies. Many of those women opt to have their breasts surgically reconstructed, most commonly with implants, but a relatively high percentage develop infections after implant surgery, requiring intravenous antibiotics and often removal of the implant. This can lead to additional surgeries, delays in cancer care and increased costs, as well as added emotional distress for women already under strain from cancer diagnosis and treatment.

Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to perform specific jobs in nature. But these elegant structures form only under narrow pH and temperature conditions, a property dictated by billions of years of evolution that has limited efforts to develop synthetic, protein-based advanced materials.

The findings indicate the material, which was until now thought near-impossible to make, can act as a highly effective semiconductor—a key component of modern electrical devices.

In a typical online meeting, humans don't always wait politely for their turn to speak. They interrupt to express strong agreement, stay silent when they are unsure, and let their personalities shape the flow of the discussion. Yet, when artificial intelligence (AI) agents are programmed to debate or collaborate, they are usually forced into a rigid, round-robin structure that stifles this natural dynamic.

Researchers have developed an AI control system that enables soft robotic arms to learn a wide repertoire of motions and tasks once, then adjust to new scenarios on the fly without needing retraining or sacrificing functionality. This breakthrough brings soft robotics closer to human-like adaptability for real-world applications, such as in assistive robotics, rehabilitation robots, and wearable or medical soft robots, by making them more intelligent, versatile, and safe. The research team includes Singapore-MIT Alliance for Research and Technology's (SMART) Mens, Manus & Machina (M3S) interdisciplinary research group, and National University of Singapore (NUS), alongside collaborators from Massachusetts Institute of Technology (MIT) and Nanyang Technological University (NTU Singapore).

Conventional lithium-ion batteries contain problematic substances such as nickel and cobalt, and the solvents used to coat the electrode materials are also toxic. Materials scientists at Saarland University are therefore working to develop environmentally friendly alternatives. By introducing finely dispersed iron oxide into tiny, highly porous, hollow carbon spheres developed by Professor Michael Elsaesser at the University of Salzburg, the Saarbrücken team has achieved some very promising results: higher storage capacities using materials that are both readily available and environmentally far less problematic. These results have now been published in Chemistry of Materials.

Taiwan's chipmaker TSMC said Thursday it will be manufacturing some of the world's most cutting-edge semiconductors in Japan to meet booming artificial intelligence-related demand, in a boost for the country's chipmaking ambitions.

What if the energy produced by wind turbines on a beautiful summer day could be stored until January to heat homes in the dead of winter? It might be possible, thanks to the discovery of a new organic molecule that can hold a charge for months with virtually no loss of energy. Dubbed AzoBiPy, the molecule was developed by a research team in the Department of Chemistry at Université de Montréal in collaboration with Concordia University researchers. Their results were published in the Journal of the American Chemical Society.

Skeleton is an exhilarating Winter Olympic sport in which athletes race head-first down an ice track at speeds reaching over 80 miles per hour (130km/h). While the event can look basic at first glance, success relies heavily on highly engineered equipment and extensive wind-tunnel testing—much like elite Olympic track cycling programs.

High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are made of heavy, inflexible metal tubes with an even heavier flange on either end, neither of which is ideal for space applications.
