Researchers have developed an environmentally friendly way to transform discarded orange peels into a highly efficient material that can remove toxic dyes from wastewater, offering a sustainable solution to two growing global challenges: agricultural waste management and water pollution. Industrial dye pollution is a major environmental problem worldwide. Each year, more than 700,000 tons of synthetic dyes are produced, and a significant portion enters waterways due to incomplete treatment. Even at low concentrations, dyes can discolor water, block sunlight essential for aquatic life, and produce harmful compounds that pose risks to human and ecosystem ...

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. ATP powers nearly every biological task, from muscle contraction to neural signaling, by breaking high-energy phosphate bonds and being continually recharged through metabolism. This life-sustaining energy cycle depends on highly coordinated flows of electrons within respiratory supercomplexes. ...

Opioid overdoses continue to take a devastating toll across the United States. According to the U.S. Centers for Disease Control and Prevention (CDC), in 2023, the nation recorded roughly 105,000 drug overdose deaths overall, with nearly 80,000 deaths involving opioids. Worldwide, opioids are also responsible for the majority of drug-related deaths. A University of California San Diego study is working on a potentially life-saving measure that may be as simple as strapping on a smartwatch. Researchers have ...

Cardiovascular disease results in around 20 million deaths worldwide and causes around a quarter of all deaths in the UK. Statins are highly effective drugs that lower LDL (“bad”) cholesterol levels and have been repeatedly proven to reduce the risk of cardiovascular disease. However, there have been concerns about possible side effects. The researchers gathered data from 23 large-scale randomised studies from the Cholesterol Treatment Trialists’ Collaboration: 123,940 participants in 19 large-scale clinical trials comparing the effects of statin therapies against a placebo (or dummy tablet), and 30,724 participants in four trials comparing more intensive versus less intensive ...

RIVERSIDE, Calif. -- Ryan Milton, a fourth-year doctoral student in nuclear physics at UC Riverside, has been awarded a U.S. Department of Energy’s Office of Science Graduate Student Research (SCGSR) Fellowship. The fellowship, which provides a $3,600 monthly stipend for one year, will support his research at the SLAC National Accelerator Laboratory, part of Stanford University. “My research focuses on developing and deploying AI tools to understand the behavior of protons and neutrons in nuclei,” Milton said. “Each proton and neutron is made of quarks, but we still don’t fully understand ...

COLLEGE PARK, Md. – Following one of the largest sewage spills in U.S. history, University of Maryland researchers have detected high levels of fecal-related bacteria and disease-causing pathogens in the Potomac River, raising urgent public health concerns and underscoring the risks posed by aging sewer infrastructure.  Water sample results collected at the site by researchers show high levels of E. coli are present along with Staphylococcus aureus (the bacteria that causes Staph infections). An antibiotic-resistant strain of S. aureus, MRSA, was also identified at the site of the sewage overflow. “People coming into contact with the impacted ...

Cambridge, MA – A longstanding goal of immunotherapies and vaccine research is to induce antibodies in humans that neutralize deadly viruses such as HIV and influenza. Of particular interest are antibodies that are “broadly neutralizing,” meaning they can in principle eliminate multiple strains of a virus such as HIV, which mutates rapidly to evade the human immune system. Researchers at MIT and the Scripps Research Institute have now developed a vaccine that generates a significant population of rare precursor B cells that are capable of evolving to produce broadly neutralizing antibodies. Expanding these cells is the first step toward a successful HIV ...

In a series of tea party-like experiments, Johns Hopkins University researchers demonstrate for the first time that apes can use their imagination and play pretend, an ability thought to be uniquely human. Consistently and robustly across three experiments, one bonobo engaged with cups of imaginary juice and bowls of pretend grapes, challenging long-held assumptions about the abilities of animals. The findings suggest that the capacity to understand pretend objects is within the cognitive potential of, at least, an enculturated ape, and likely dates back 6 to 9 million years, to our common evolutionary ...

Marking a significant step toward a quantum-secure internet, researchers have demonstrated device-independent quantum key distribution over optical fibers spanning 100 kilometers (km). The findings show that cryptographic security can be guaranteed with this method, at the metropolitan scale – which represents a much greater distance than previous efforts – and help to close the gap between proof-of-principle quantum network experiments and real-world applications. Quantum key distribution (QKD) is a leading application of quantum technologies, enabling ultra-secure digital communications. Early forms of QKD derive security using trusted ...

Around the world, the total toxicity and ecological harm from agricultural pesticides are rising, despite recent United Nations commitments to halve pesticide use and risks by 2030. The findings establish a global, toxicity-weighted baseline for pesticide use and identify a subset of pesticides, crops, and countries driving the most biodiversity impacts. The widespread use of agricultural pesticides is a growing threat to global biodiversity. To address this concern, the 15th United Nations Biodiversity Conference set the goal of halving pesticide use and risk by 2030 and recently adopted a new global indicator – total applied toxicity (TAT) – that captures not just ...

A temporary weakening of the atmosphere’s chemical capacity to break down methane, combined with elevated emissions from tropical wetlands, drove the sharp increase in atmospheric methane observed in 2020 to 2021, according to a new study. Methane (CH4) is a significant contributor to atmospheric warming. In the early 2020s, the amount of atmospheric CH4 grew faster than ever before observed, peaking at 16.2 parts per billion per year (ppb yr-1), before declining to 8.6 ppb yr-1 in 2023. It’s hypothesized that this surge was driven by a combination of increased natural emissions and a coincident decrease in the atmosphere’s oxidizing capacity, namely, fewer OH ...

In a Policy Forum, Doni Bloomfield and colleagues discuss the need for expanded – yet tailored and flexible – governance for the biological data used to develop powerful artificial intelligence (AI) models. Rapidly advancing AI systems trained on biological data have enabled researchers to design new molecules, predict protein structure and function, and probe vast and highly complex biological datasets for novel insights that could greatly expand our understanding of nature and human health. However, these same tools could also be misused for dangerous purposes, such as designing harmful pathogens or generating genetic ...

At the 15th UN Biodiversity Conference (COP15) in Montreal, Canada, in 2022, nations committed to reducing the risks associated with pesticide use in agriculture by 50% by 2030. A new study by a research team from RPTUKaiserslautern-Landau, published in the journal Science, reveals that this global target is now under serious threat. Using a novel analytical method, the researchers assessed trends in pesticide toxicity worldwide and found that current trajectories fall far short of the 2030 goal. The study concludes that immediate, coordinated ...

LA JOLLA, CA—One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and antibodies. In most vaccines, HIV proteins are attached to a larger protein scaffolding that mimics a virus. Then, a person’s immune system produces a range of antibodies that recognize different bits of those proteins. Often, however, some of those antibodies react not to HIV itself—but to the scaffold used to deliver the vaccine. Now, researchers at Scripps Research and the Massachusetts Institute of Technology (MIT) have developed a new kind ...

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth’s crust but in our planet’s mantle, the layer sandwiched between the thin crust and Earth’s molten core. The new map will help scientists learn more about the mechanics of mantle earthquakes, in turn opening a window into the complexities and triggers for all earthquakes. As reported in a study published Feb. 5 in Science, continental mantle earthquakes occur worldwide but are clustered regionally, particularly in the Himalayas in southern Asia and the ...

Chestnut Hill, Mass (2/5/2026) – A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early 2020s, an international team of researchers report today in the journal Science. A sharp decline in hydroxyl radicals – the primary “cleaning agent” that breaks down methane in the atmosphere – during 2020–2021 explains roughly 80 percent of the year-to-year variation in methane accumulation, according to the team, including Boston College Professor of Earth and Environmental Science Hanqin Tian. At the same time, ...

PHILADELPHIA (February 5, 2026) — For many Americans, a routine surgical procedure serves as their first introduction to opioid pain medication. While most stop using these drugs as they heal, a considerable number of "opioid-naïve" patients transition into New Persistent Opioid Use (NPOU)—continuing use long after the typical recovery period. A new systematic review and meta-analysis led by Penn Nursing researchers, published in Pain Medicine, has identified the specific patient-related risk factors that most accurately predict which individuals are at the highest risk for this dangerous transition. The ...

Excess carbon dioxide in the atmosphere, polluted water, and increasingly strict environmental regulations are driving the search for materials that can efficiently trap pollutants at the molecular level. For more than two decades, this challenge has drawn scientific attention to metal–organic frameworks (MOFs) – highly advanced porous materials widely regarded as one of the most promising tools for tackling climate change and environmental pollution. The importance of this research field was recognised in 2025, when the Nobel Prize in Chemistry was awarded to the scientists who developed MOFs. Despite this recognition and their ...

The fellowship includes a grant of more than $150,000 that will support research focused on weight gain markers. Her research project, “Examination of Metabolic Characteristics in the Predisposition for Weight Gain,” will reexamine existing clinical trial data with the goal of improving prediction ...

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 from The University of Electro-Communications and the National Institute of Advanced Industrial Science and Technology (AIST) have demonstrated that allowing AI agents to break these rules can actually make them smarter. Their new ...

About The Study: Among patients with non–large vessel occlusion acute ischemic stroke and salvageable brain tissue, intravenous tenecteplase, a modified human tissue plasminogen activator, administered 4.5 to 24 hours after onset resulted in a greater likelihood of an excellent functional outcome at 90 days than standard care but had an increased risk of symptomatic intracranial hemorrhage.

Predicting tumour progression is one of the major challenges in oncology. Scientists at the University of Geneva (UNIGE) and the Ludwig Institute for Cancer Research have discovered that neutrophils, a type of immune cell, undergo reprogramming when they come into contact with the tumour ecosystem and contribute to its progression. They then produce a molecule — the chemokine CCL3 — which promotes cancer growth rather than fighting it. This mechanism appears to be a major variable in tumour biology and could serve ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists has carried out one of the most stringent experimental tests to date of this foundational rule of quantum physics and has found no evidence of its violation. Using the VIP-2 experiment, the team has set the strongest limits so far for possible violations involving electrons in atomic systems, significantly constraining a range of speculative theories beyond the Standard Model, including those that suggest electrons have internal structure, and so-called ‘Quon models.’ Their ...
