MIAMI, FL – February 15, 2024 – A study co-led by researchers at Miami Cancer Institute, part of Baptist Health South Florida, found that ablative stereotactic magnetic resonance (MR)-guided adaptive radiation therapy may improve local control (LC) and overall survival (OS) in patients with borderline resectable (BRPC) and locally advanced pancreas cancer (LAPC). Long-term outcomes from the Phase 2 SMART trial demonstrate encouraging OS and limited toxicity as published recently in Radiotherapy & Oncology (“The Green Journal”). “Pancreatic ductal adenocarcinoma is a leading cause of cancer death. Surgery is the only known ...

One of the grand challenges for materials science is the design and discovery of new materials that address global priorities such as Net Zero. In a paper published in the journal Science, researchers at the University of Liverpool have discovered a solid material that rapidly conducts lithium ions. Such lithium electrolytes are essential components in the rechargeable batteries that power electric vehicles and many electronic devices. Consisting of non-toxic earth-abundant elements, the new material has high ...

Why do Serengeti zebra, wildebeest, and gazelle – all sharing limited food resources – follow the same migratory routes, one after another, in a body-size dependent way? This longstanding question has now been evaluated by researchers who used novel data to show how a balance of species interactions and ecological factors regulate this process. They say competition pushes zebra ahead of the wildebeest, and wildebeest then eat plants in a way that facilitates development of newer growth the trailing gazelle like. “Our results highlight a balance between facilitative and competitive forces,” the authors say. Large seasonal migrations are a ...

Oxygenation in the tropical North Pacific Ocean increased during a warm climatic interval that occurred roughly 56 million years ago, despite high global temperatures, according to a new study. Its findings offer insights into how modern tropical oceans may respond to ongoing anthropogenic climate warming. The availability and distribution of dissolved oxygen in Earth’s oceans play a fundamental role in supporting marine ecosystems and marine life. However, oxygen in the global oceans is declining in response to anthropogenic warming. Although these trends writ large are predicted to continue, the future of oxygen in the highly productive ...

Cresomycin – a novel synthetic molecule – demonstrates remarkably robust efficacy against multiple, evolutionary divergent forms of antimicrobial resistance (AMR), researchers report. The emergence and widespread distribution of bacteria broadly resistant to approved antibiotics raises serious global public health concerns. Given the growing rate of deaths attributable to antimicrobial resistance (AMR) worldwide, it’s evident the pace of discovery and development of antibiotics effective against AMR has not kept up with the need. Many small ...

Scientists have observed so-called 'roaming' chemical reactions, those that at certain points move away from the lowest minimum energy 'path of least resistance', in highly excited energy states for the first time.   Chemical reactions are supposed to occur along their minimum energy paths. In recent years, so-called roaming reactions that stray far from this path have begun to be observed, but only for chemical species in their ground state or, at most, their first excited state. However, researchers have now observed a roaming reaction even in highly excited energy states. The researchers ...

Researchers at Michigan State University and the Carnegie Institution for Science have developed a model that connects microscopic biology to macroscopic ecology, which could deepen our understanding of nature’s laws and create new opportunities in ecosystem management. Reporting in the journal Science on Feb. 16, the team showed how microscopic relationships in plankton — such as between an organism’s size and nutrient consumption — scales up to predictably affect food webs. “Using data that other researchers have measured at the microscale about these organisms, our model can predict what’s happening at the scale of whole ecosystems,” said Jonas ...

RICHLAND, Wash.—In an experiment akin to stop-motion photography, scientists have isolated the energetic movement of an electron while “freezing” the motion of the much larger atom it orbits in a sample of liquid water. The findings, reported today in the journal Science, provide a new window into the electronic structure of molecules in the liquid phase on a timescale previously unattainable with X-rays. The new technique reveals the immediate electronic response when a target is hit with an X-ray, an important step in understanding the effects of radiation exposure on objects and people. “The chemical reactions induced by radiation ...

A new antibiotic created by Harvard researchers overcomes antimicrobial resistance mechanisms that have rendered many modern drugs ineffective and are driving a global public health crisis. A team led by Andrew Myers, Amory Houghton Professor of Chemistry and Chemical Biology, reports in Science that their synthetic compound, cresomycin, kills many strains of drug-resistant bacteria, including Staphylococcus aureus and Pseudomonas aeruginosa. “While we don’t yet know whether cresomycin and drugs like it are safe ...

CAMBRIDGE, MA — A simple technique that uses small amounts of energy could boost the efficiency of some key chemical processing reactions, by up to a factor of 100,000, MIT researchers report. These reactions are at the heart of petrochemical processing, pharmaceutical manufacturing, and many other industrial chemical processes. The surprising findings are reported today in the journal Science, in a paper by MIT graduate student Karl Westendorff, professors Yogesh Surendranath and Yuriy Roman-Leshkov, and two others. “The results are really striking,” says Surendranath, a professor of chemistry ...

The natural ends of chromosomes appear alarmingly like broken DNA, much as a snapped spaghetti strand is difficult to distinguish from its intact counterparts. Yet every cell in our bodies must have a way of differentiating between the two because the best way to protect the healthy end of a chromosome also happens to be the worst way to repair damaged DNA.   Consider the enzyme telomerase, which is responsible for maintaining protective telomeres at the natural ends of chromosomes. Were telomerase to seal off a broken strand of DNA with a telomere, it would prevent further repair of that break and delete essential genes. Now, a new study in Science describes how cells avoid ...

Upending the prevailing theory of how and why multi-species mass-migration patterns occur in Serengeti National Park, researchers from Wake Forest University have confirmed that the millions-strong wildebeest population pushes zebra herds along in competition for the most nutrient-dense grasses. The study resulting from this research, “Interplay of competition and facilitation in grazing succession by migrant Serengeti herbivores,” appears today in the peer-reviewed journal Science. For decades, biologists have believed the major grazing ...

Irvine, Calif., Feb. 15, 2024 – Throughout human history, technologies have been used to make peoples’ lives richer and more comfortable, but they have also contributed to a global crisis threatening Earth’s climate, ecosystems and even our own survival. Researchers at the University of California, Irvine, the University of Kansas and Oregon State University have suggested that industrial civilization’s best way forward may entail embracing further technological advancements but doing so with greater awareness of their potential drawbacks.   In a paper titled “Scientists’ Warning on Technology,” published recently in the Journal of Cleaner ...

– By Julie Bobyock Wetlands are Earth’s largest natural source of methane, a potent greenhouse gas that is about 30 times more powerful than carbon dioxide at warming the atmosphere. A research team from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) analyzed wetland methane emissions data across the entire Boreal-Arctic region and found that these emissions have increased approximately nine percent since 2002.  Livestock and fossil fuel production are well studied for their role in releasing tons of methane per year into the atmosphere. Although more uncertain, quantifying natural wetlands emissions is important to predicting climate ...
