Why does the universe contain matter and (virtually) no antimatter? The BASE international research collaboration at the European Organisation for Nuclear Research (CERN) in Geneva, headed by Professor Dr Stefan Ulmer from Heinrich Heine University Düsseldorf (HHU), has achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before – and thus identify possible matter-antimatter asymmetries. BASE has developed a trap, which can cool individual antiprotons much more rapidly ...

The proliferation of concrete infrastructure worldwide has been met with growing concerns over its durability and safety. Concrete structures are increasingly subjected to dynamic forces from natural disasters like earthquakes and environmental degradation, such as corrosion. These factors, coupled with the saturation of infrastructure projects, amplify the risks associated with structural failure. Consequently, there is a pressing need for effective structural health monitoring (SHM) systems that can preemptively identify and address these vulnerabilities. The ...

In recent years, microwave technology has dramatically progressed, marked by the arrival of the 5G era, owing to the advantages of electromagnetic waves in long-distance, wireless, and high-speed transmissions. However, electromagnetic wave pollution problems such as electromagnetic wave interference and electromagnetic wave radiation are becoming increasingly serious. Electromagnetic wave pollution not only affects the normal operation of electronic equipment, greatly threatens the information security of the scientific community, but also endangers human health and is a possible cause of cancer ...

NEW YORK CITY, August 2, 2024 — According to American Heart Association data, nine out of every ten people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of the time. CPR, especially if performed immediately, can double or triple a person’s chance of survival. That is why the American Heart Association and the National Women’s Soccer League (NWSL) brought cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) training to NWSL staff at the New York headquarters office located on Madison ...

Cavendish physicists have discovered two new ways to improve organic semiconductors. They found a way to remove more electrons from the material than previously possible and used unexpected properties in an environment known as the non-equilibrium state, boosting its performance for use in electronic devices. “We really wanted to hit the nail and figure out what is happening when you heavily dope polymer semiconductors,’ said Dr Dionisius Tjhe, Postdoctoral Research Associate at the Cavendish Laboratory. Doping is the process of removing or adding electrons into a semiconductor, increasing its ability to ...

Housing policies may be becoming more pet inclusive, but housing insecurity is getting worse, finds a new study that examined the housing issues that led to owners turning their pets over to an animal shelter. “Over the duration of the study, instances of animals entering shelters due to loss of housing rose, while those due to pet restrictions and landlord conflicts declined,” said the study’s lead author Jennifer Applebaum, Ph.D., an assistant professor in the Department of Environmental and Global Health in the University ...

Eye-tracking allows studying aspects that cannot be seen, for example, the thinking processes of a student solving a mathematical problem. Researchers at Kaunas University of Technology (KTU) are the first in Lithuania to integrate eye-tracking into education and are using the technology to radically improve the teaching of mathematics. Eye-tracking creates the possibility for researchers to observe a subject’s attention shifts based on where they fix their gaze or how they move it. This helps researchers understand various emotional, thinking and cognitive processes that happen in response to the environment. “By applying this technology in mathematical education, ...

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals’ genes evolved to express themselves differently, leading to signatures of domestication — such as weaker bones and better viral resistance — in pigs and chickens, according to a research team based in Japan. The findings, published on July 6 in Animals, could provide insight into the genetic changes of the domestication process and highlight target genes for healthier and more productive livestock breeding, the researchers ...

A recent study published in Cell Host & Microbe identifies a potential obesity-linked bacterium, Megamonas, from a large-scale cohort of obese individuals in China. This research suggests potential strategies for future obesity management by illustrating how the bacterium degrades intestinal myo-inositol, enhances lipid absorption, and contributes to obesity. The study is jointly conducted by Ruijin Hospital affiliated with Shanghai Jiao Tong University School of Medicine, BGI Research, and BGI Genomics Institute of Intelligent Medical Research (IIMR). "Through a large-scale study of intestinal ...

Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun’s harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant that can trigger chronic health problems including chest pain, difficulty breathing, and impaired lung function.  And somewhere in between, in the upper troposphere — the layer of the atmosphere just below the stratosphere, where most aircraft cruise — ozone contributes to warming the planet as a potent greenhouse gas. There are signs that ozone is continuing to rise in the upper troposphere despite efforts to reduce its ...

A new pathway that is used by cancer cells to infiltrate the brain has been discovered by a team of Canadian and American research groups led by the Singh Lab at McMaster University. The research also reveals a new therapy that shows promise in blocking and killing these tumors. The research, published in Nature Medicine on Aug. 2, 2024, offers new hope and potential treatments for glioblastoma, the most aggressive form of brain cancer. With existing treatments like surgery, radiation therapy and chemotherapy, the tumors often return, and patient survival is limited to only a few months. With this new treatment, ...

Scientists have developed a new, safe and effective way to infect volunteers with the parasite that causes leishmaniasis and measure the body’s immune response, bringing a vaccine for the neglected tropical disease a step closer.   The breakthrough, by a team from the University of York and Hull York Medical School, is described in the journal Nature Medicine and lays the foundations for vaccine development and for testing new preventative measures. Controlled human infection studies, where volunteers are exposed to small amounts of ...

Two of the planet’s more pressing environmental stressors have the potential to alter the growth and reproductive output of plants found right along the world’s coastlines, a new study suggests. The research, published in the journal Environmental Pollution, is one of the first to examine the combined effects of seawater flooding and microplastic pollution on coastal plants. It showed that both stressors had some effects on the species tested, with microplastics impacting the plants’ reproduction while flooding caused greater tissue death. However, being exposed to both microplastics ...

A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals. The study reveals clues into the forces that drove the evolution of the earliest organisms, from which all major animal groups descended. A team from the University of Edinburgh studied a compilation of rocks and fossils from the so-called Ediacaran-Cambrian interval – a slice of time 580–510 million years ago. This period witnessed an explosion of biodiversity according to fossil records, the causes of which have ...

In 1935, the Metropolitan Museum of New York led an archaeological expedition to Egypt. In Deir Elbahari near Luxor, the site of ancient Thebes, they excavated the tomb of Senmut, the architect and overseer of royal works – and reputedly, lover – of the famed queen Hatschepsut (1479-1458 BCE). Beneath Senmut's tomb, they found a separate burial chamber for his mother Hat-Nufer and other, unidentified relatives. Here, they made an uncanny discovery: a wooden coffin holding the mummy of an elderly woman, wearing a black wig and two scarab rings in silver and gold. But what struck the archaeologists was the ...

Similar to other sectors around the world, the light speed development of artificial intelligence (AI) has made its way into healthcare, particularly the radiology field. As such, AI-based diagnostic systems are flourishing, with hospitals quickly adopting the technology to assist radiologists. In contrast, there are concerns about the environmental impact of increasingly complex AI models and the need for more sustainable AI solutions. Therefore, Associate Professor Daiju Ueda of Osaka Metropolitan University’s ...

Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission bands, and the color is determined by the transition energy levels, molecular vibrations and rotations. There is a variety of characteristic colors of auroras, such as green and red, but there are multiple theories about the emission process by which they appear in different types of auroras, and to understand the colors of auroras, the light must be broken down. ...

Mountain hikes are invigorating. Crisp air and clear views can refresh the soul, but thin air presents an additional challenge for high-altitude birds. ‘All else being equal, bird wings produce less lift in low density air’, says Jonathan Rader from the University of North Carolina (UNC) at Chapel Hill, USA, making it more difficult to remain aloft. Yet this doesn’t seem to put them off. Bar-headed geese, cranes and bar-tailed godwits have recorded altitude records of 6000 m and more. So how do they manage to take to the air when thin air offers ...

A drug that was developed to treat pancreatic cancer has now been shown to increase symptom-free survival in preclinical medulloblastoma models – all without showing signs of toxicity. Medulloblastoma is the most common malignant brain tumor in children. Survival rates vary according to which one of the four subtypes a patient has, but the worst survival rates, historically at about 40%, are for Group 3, which this research focused on. Jezabel Rodriguez Blanco, Ph.D., an assistant professor who holds dual appointments at MUSC Hollings Cancer Center and the Darby Children’s ...

MADISON — As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers at the University of Wisconsin–Madison and their collaborators have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago. That would make the tropical Andes the first region in the world known to pass that threshold as a result of the steadily warming global climate. It also makes them possible harbingers of what's to come for glaciers globally. "We think these are the canary ...

Scientists at St. Jude Children’s Research Hospital have created a panel that is able to provide a diagnosis for >90% of pediatric cancer patients by sequencing 0.15% of the human genome. The panel is a cost-effective way to test and classify childhood malignancies and to help guide patient treatment. The panel’s performance and validation were published this week in Clinical Cancer Research. Finding the mutations in a child’s cancer with powerful sequencing technology can lead to better outcomes. Physicians use that knowledge to tailor targeted treatments to the specific cancer-causing mutations affecting each patient. However, current ...

Prior authorization—the process by which a health insurance company denies or approves coverage for a health care service before the service is performed—became standard practice beginning with Medicare and Medicaid legislation in the 1960s. Although research has uncovered disparities in prior coverage for cancer patients based on race, little has been known to date on the role of prior authorization in increasing or decreasing these disparities. To learn more about the issue, Benjamin Ukert, PhD, an assistant professor of health policy and management in the Texas A&M ...

UNIVERSITY PARK, Pa. — Snacks provide, on average, about one-fourth of most people’s daily calories. With nearly one in three adults in the United States overweight and more than two in five with obesity, according to the National Institutes of Health, researchers in the Penn State Sensory Evaluation Center are investigating how Americans can snack smarter. The latest study conducted in the center, housed in the College of Agricultural Sciences, investigated how eating behavior changes when consumers are served a dip with a salty snack. The findings, available online now and to be published in the November issue ...
