□ DGIST (President Lee Kunwoo) Department of Brain Sciences Professor Lee Kwang and his team have discovered a new correlation between neural signaling in the brain and dopamine signaling in the striatum. The human brain requires fast neural signal processing in a short period of less than a second. Dopamine is known to have the strongest effect on brain neural signals, but the research team’s newly developed “optical neural chip-based multiple brain signal monitoring technology” shows that changes in dopamine signals within the physiological range do not affect brain neural signal ...

□ A team led by Professor Seo Dae-ha of the Department of Physics and Chemistry at DGIST (President Lee Kun-woo) has developed new real-time microscopy technology and successfully observed the behavior of “motor proteins”[1], which may hold the key to unraveling the efficient material transport strategy of cells. The research team used nanoparticle probe, high-resolution microscopy, and Fourier transform algorithm technologies to develop “Fourier transform-based plasmonic dark-field microscopy” (FT-pdf microscopy) with positional and angular accuracy comparable to electron microscopy, achieving the highest level of existing ...

Injuries, infection and inflammatory diseases that damage the spinal cord can lead to intractable pain and disability. Some degree of recovery may be possible. The question is, how best to stimulate the regrowth and healing of damaged nerves. At the Vanderbilt University Institute of Imaging Science (VUIIS), scientists are focusing on a previously understudied part of the brain and spinal cord — white matter. Their discoveries could lead to treatments that restore nerve activity through the targeted delivery of electromagnetic stimuli or drugs. As in the brain, the spinal cord is made up nerve cell bodies (gray matter), which process sensation and control voluntary movement, and ...

The U.S. Food and Drug Administration (FDA) has granted accelerated approval for the immunotherapy afamitresgene autoleuecel (Tecelra®, also known as afami-cel) for the treatment of adults with a rare soft tissue cancer called synovial sarcoma. Afami-cel is the first engineered T cell therapy to receive FDA approval for a solid tumor cancer.  The clinical trial that resulted in the drug’s approval was led by Memorial Sloan Kettering Cancer Center (MSK) sarcoma specialist and immunotherapy expert Sandra D’Angelo, MD.  “This treatment offers an important new option for people with this rare cancer,” Dr. D’Angelo ...

Emory researcher David Weiss has spent years studying a baffling phenomenon called heteroresistance, in which a tiny fraction of bacteria remain resistant to antibiotics, while the remainder succumb. Recently, he brought his scientific acumen to the equally deadly threat of fungal bloodstream infections in patients receiving bone marrow transplants. Bloodstream infections can be lethal in these patients, including infections from Candida parapsilosis, a species of fungi that can live in the digestive tract and occasionally make it into the bloodstream. Weiss partnered ...

When two people interact, their brain activity becomes synchronized, but it was unclear until now to what extent this “brain-to-brain coupling” is due to linguistic information or other factors, such as body language or tone of voice. Researchers report August 2 in the journal Neuron that brain-to-brain coupling during conversation can be modeled by considering the words used during that conversation, and the context in which they are used. “We can see linguistic content emerge word-by-word ...

About The Study: The number of prescriptions filled for semaglutide has increased substantially, reaching 2.6 million prescriptions filled at retail pharmacies by December 2023. While Ozempic persistently accounted for most semaglutide fills, increases were considerably greater for Wegovy since its approval for weight loss in June 2021. These increases, which primarily occurred following increased awareness of weight-loss benefits in late 2022, are likely contributing to the FDA-reported shortage of Ozempic and Wegovy first issued in March 2022. Despite the disproportionate burden of obesity in Medicaid and Medicare Part D populations, and recent increases in public spending ...

About The Study: This qualitative study found that semaglutide products are actively being sold without prescription by illegal online pharmacies, with vendors shipping unregistered and falsified products. Two websites evaluated were sent FDA warning letters for unlawful sale of unapproved and misbranded semaglutide.

Inflammation is the body's response to harmful stimuli, characterized by heat, pain, redness, swelling, and loss of tissue function. When balanced, inflammation protects the body by clearing harmful agents and initiating tissue repair. However, excessive inflammation can cause tissue destruction and disease. Key players in this process are various immune cells, which work together during inflammation. The type of immune cells involved often varies depending on the harmful stimulus, influencing the outcome of the inflammatory response. Immune cell trapping during allergic responses Mast cells, residing in tissues and critical for initiating ...

A new USC study suggests that publicly insured individuals who are most likely to benefit from new drugs for diabetes and obesity are less likely to get them than those with private insurance. Prescription fills for the drug best known as Ozempic or Wegovy — semaglutide — increased by more than 400% between January 2021 and December 2023, according to research out today in  JAMA Health Forum. Approved first for type 2 diabetes, then for weight loss, studies show that semaglutide also improves blood pressure and reduces cardiovascular disease — problems that plague millions of Americans. Yet the lion’s share of prescriptions ...

The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team at ORIGINS, a Munich-based Cluster of Excellence, has demonstrated a mechanism that could have enabled the first RNA molecules to stabilize in the primordial soup. When two RNA strands combine, their stability and lifespan increase significantly. In all likelihood, life on Earth began in water, perhaps in a tide pool that was cut off from seawater at low tide but flooded by waves at high tide. Over billions of years, complex molecules like DNA, RNA and proteins ...

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, ...
