Batteries have become an integral component of modern technology. Lithium-ion batteries (LIBs) can be found virtually everywhere, from handheld electronic devices and electric vehicles to the large power banks used in renewable energy generation systems. However, current LIB designs suffer from some crippling drawbacks, including low durability and the use of toxic liquid electrolytes. To address these limitations, scientists have been studying all-solid-state batteries for over a decade. Although silicon-based all-solid-state batteries should be theoretically more durable than conventional LIBs, ...

By Jenifer Fouch University of Arkansas System Division of Agriculture Arkansas Agricultural Experiment Station FAYETTEVILLE, Ark. — Causing an estimated $160 billion in damages globally each year, one of agriculture’s biggest enemies is too small to see without a microscope. Plant-parasitic nematodes feed on agricultural crops at their roots, reducing yields and profits for producers. In the U.S., soybean producers lose about 11 percent of their crops to soybean diseases, including the southern root-knot nematode, Meloidogyne incognita, or SRKN as it’s commonly known. The nematode forms abnormal growths — or knots — in soybean ...

BIRMINGHAM, Ala. – Immune checkpoint blockades, or ICBs, have revolutionized treatment for various advanced cancers. However, their effectiveness has plateaued due to therapeutic resistance that renders tumor-infiltrating lymphocytes, or TILs, ineffective. Thus, finding ways to disarm that resistance and rejuvenate anti-cancer TILs — so they can kill tumor cells — is an important goal for cancer clinicians. Yet any potential intervention has to take place under unusual conditions — the cancer microenvironment nearly devoid of oxygen due to fast ...

PHILADELPHIA – During a shortage of the generic platinum chemotherapy drugs cisplatin and carboplatin that began in early 2023, there was no difference in mortality rates among patients with advanced cancer compared to the previous year, and prescription rates for the two drugs fell less than three percent overall—and 15.1 percent at the peak—according to an analysis published this week in the Journal of the National Cancer Institute by researchers from the University of Pennsylvania’s Perelman ...

A new study led by UCLA Health Jonsson Comprehensive Cancer Center investigators offers new evidence that dietary changes may help reduce cancer cell growth in patients undergoing active surveillance, a treatment approach that involves regular monitoring of the cancer without immediate intervention. The findings, published in the Journal of Clinical Oncology, show that a diet low in omega-6 and high in omega-3 fatty acids, combined with fish oil supplements, significantly reduced the growth rate of prostate cancer cells in men with early-stage disease. “This ...

UNIVERSITY PARK, Pa. — Dark-humored memes — like “This is fine,” featuring a dog wearing a bowler hat in a room on fire — tend to dominate social media during times when the world appears to be falling apart. But what bothers people most can spur action and change, especially on the local level, according to Lisa Silvestri, associate teaching professor of communication arts and sciences at Penn State. Silvestri shifted her research focus to peace- and community building after studying ...

Physics lab courses are vital to science education, providing hands-on experience and technical skills that lectures can’t offer. Yet, it’s challenging for those in Physics Education Research (PER) to compare course to course, especially since these courses vary wildly worldwide.  To better understand these differences, JILA Fellow and University of Colorado Boulder physics professor Heather Lewandowski and a group of international collaborators are working towards creating a global taxonomy, a classification system that could create a more equitable way to compare these courses. Their findings were recently ...

Key takeaways The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the galaxy’s center. An international research team including UCLA has observed a teraelectronvolt gamma-ray flare seven orders of magnitude — tens of millions of times — larger than the event horizon, or surface of the black hole itself.  A flare of this intensity — which has not been observed in over a decade —  can offer crucial insights ...

Multinational enterprises (MNEs) are not just falling short of global sustainability targets but are actively contributing to the very problems they claim to address, according to a new study from the University of Surrey. This study argues that there is an urgent need for MNEs to reassess their innovation strategies to align with the United Nations Sustainable Development Goals (SDGs). The research team found that many MNEs are prioritising profit over sustainable practices. The study highlights how MNEs often adopt superficial compliance measures rather than engaging in meaningful, sustainable innovations by analysing case studies from various countries, including both advanced ...

Australian-led research is unlocking new ways for immunotherapy to better target cancer.  Cancer immunotherapy has revolutionised treatment for patients, whereby the body’s own immune system is harnessed to destroy cancer cells.  Typically, several molecules restrain the ability of T cells to target cancer cells and developing approaches to limit this restraining effect can lead to improved effectiveness of cancer immunotherapy.   Research published in Science Immunology has determined the structure of how an inhibitory molecule, LAG3, interacts with its main ligand and provides a new targeted approach to ...

A new twist: the molecular machines that loop our chromosomes also twist DNA Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they now discovered that these motors also put significant twists into the loops that they form. These findings help us better understand the structure and function of our chromosomes. They also provide insight into how disruption of twisted DNA looping can affect health—for instance, in developmental ...

The air around us contains a powerful solution for making agriculture more sustainable. Researchers at Stanford University and King Fahd University of Petroleum and Minerals in Saudi Arabia have developed a prototype device that can produce ammonia – a key fertilizer ingredient – using wind energy to draw air through a mesh. The approach they developed, if perfected, might eliminate the need for a century-old method that produces ammonia by combining nitrogen and hydrogen at high pressures and temperatures. The older method consumes 2% of global energy and contributes 1% of annual carbon dioxide emissions from its ...

An international team of researchers, including a glaciologist at Newcastle University, UK, has discovered remarkably well-preserved glacial landforms buried almost 1 km beneath the North Sea. The team used sound wave, known as seismic, data to reveal Ice Age landforms buried beneath almost 1 km of mud in the North Sea. The results, reported in the journal Science Advances, suggest that the landforms were produced about 1 million years ago, when an ice sheet centred over Norway extended towards the British Isles. This is important because the timing of this ice advance corresponds to a period of global cooling called the Mid-Pleistocene Transition. Glacial ...

Intermittent fasting has proven benefits for metabolic health, but a new study shows that it could slow hair growth—at least in mice. Researchers report December 13 in the Cell Press journal Cell that mice subjected to intermittent fasting regimes showed improved metabolic health but slower hair regeneration compared to mice with 24/7 access to food. A similar process might occur in humans, based on a small clinical trial that the team also conducted, but it’s likely to be less severe since humans have a much slower metabolic rate and different hair growth patterns compared to mice. “We don't want to scare people away ...

About The Study: The findings of this study suggest that body mass index and obesity prevalence in the U.S. decreased in 2023 for the first time in more than a decade. The most notable decrease was in the South, which had the highest observed per capita glucagon-like peptide 1 receptor agonist (GLP-1RA) dispensing rate. However, dispensing does not necessarily mean uptake, and the South also experienced disproportionately high COVID-19 mortality among individuals with obesity.  Corresponding Author: To contact the corresponding author, Benjamin Rader, PhD, MPH, email benjamin.rader@childrens.harvard.edu.

A recent study has reported a novel breeding strategy to rapidly create climate-smart crops that show higher yield under normal conditions and greatly rescue yield losses under heat stress both in staple grain and vegetable crops. The study, which was published in Cell on 13 December, was conducted by Prof. XU Cao’s team from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences. The year 2050 is fast approaching and farm productivity must increase by 60% in order to feed a projected global population of 10 billion. However, current crop production is insufficient and is expected to worsen due to the abiotic-stress burden ...

Led by researchers from the University of Oxford’s Leverhulme Centre for Demographic Science and the University of Iceland, the review explores how genetic variations can explain differences in reproductive health and longevity. The study provides the most comprehensive review of male and female genetic discoveries of reproductive traits to date, and provides new insights into how our DNA affects when we have children, the timing of menopause, and even how that is connected to how long we live.   Genes at the heart of reproduction Using the GWAS Catalog, an online database of Genome Wide Association Studies (GWAS), the researchers identified ...

Wildfire smoke has long been known to exacerbate health problems like heart disease, lung conditions, and asthma, but now a new study finds that smoke from these fires can lead to poor health thousands of miles away. Researchers from the University of Maryland Institute for Health Computing (UM-IHC) found that medical visits for heart and lung problems rose by nearly 20 percent during six days in June, 2023, when smoke from Western Canadian wildfires drifted across the country, leading to very poor air quality days in Baltimore and ...
