Halfway through a true crime podcast, a morning commuter jerks the wheel to narrowly avoid a collision. When discussing the podcast with a coworker later that day, the driver can easily recall the details of the episode’s second half but retains only a blurry recollection of how it began. A new study from psychologists at the Beckman Institute for Advanced Science and Technology suggests that we remember the moments immediately following a distressing episode more sharply than the moments leading up to it. Clarifying the relationship ...

TORONTO, Jan. 18, 2024 – The 2022 FIFA World Cup ended with a tight win for Argentina over France on penalties, but it was also a triumph for SARS-CoV-2 with a significant jump in the number of cases, some of which York University researchers say could have been prevented. New research published today and led by York used the 2022 FIFA World Cup as a case study to help determine the best ways to mitigate virus spread and hospitalizations at mass gatherings in the future. A technique was used ...

Reston, VA—A novel imaging approach, 68Ga-pentixafor PET/CT, has been shown to accurately identify sub-types of primary aldosteronism (an adrenal gland disorder), outperforming traditional methods for diagnosis. Reported in the January issue of The Journal of Nuclear Medicine, this detailed imaging technique provides a clearer picture of the adrenal glands, helping doctors decide more confidently whether surgery is the right option for patients. Primary aldosteronism is an endocrine disorder that occurs when the adrenal glands produce too much of the hormone aldosterone, frequently ...

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study, recently published in the journal PNAS, reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics. "The exceptionally slow pace of genomic evolution sets these plants apart," said Dr. Fay-Wei Li, a professor at the Boyce Thompson Institute and a senior author of the study. ...

Temperature, day length and humidity have been found to be linked to the increased spread of a diarrhoeal illness a new study from the University of Surrey reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services. During this unique study, researchers led by Dr Giovanni Lo Iacono, investigated the impact of weather on the transmission of campylobacteriosis, a bacterial infection which can cause diarrhoea and stomach pains. According to the World Health Organisation, Campylobacter infections are the most common causes of human bacterial gastroenteritis in the world. Infections are generally ...

Scientists have developed two agents, made of therapeutic nanoparticles and antibodies, that could be given to patients shortly before a blood draw to allow physicians to better detect tumor DNA in blood using a technology called liquid biopsy. Liquid biopsies promise to transform how cancers are diagnosed, monitored, and treated by detecting DNA that tumors shed into the blood. But the body presents a significant challenge. Immune cells in the liver and DNA-degrading enzymes in blood remove circulating tumor DNA from the bloodstream within minutes, making this DNA difficult to capture and detect in a blood test. To overcome this, a team from the Broad Institute of MIT and Harvard ...

CAMBRIDGE, MA -- Tumors constantly shed DNA from dying cells, which briefly circulates in the patient’s bloodstream before it is quickly broken down. Many companies have created blood tests that can pick out this tumor DNA, potentially helping doctors diagnose or monitor cancer or choose a treatment. The amount of tumor DNA circulating at any given time, however, is extremely small, so it has been challenging to develop tests sensitive enough to pick up that tiny signal. A team of researchers from MIT and the Broad Institute of MIT and Harvard has now come up with a way to significantly boost that signal, by temporarily slowing the clearance of tumor DNA circulating in the bloodstream. The ...

The cost of climate change may be six months off the average human lifespan, according to a study published January 18, 2024, in the open-access journal PLOS Climate by Amit Roy from Shahjalal University of Science and Technology and The New School for Social Research, U.S. Temperature and rainfall — two telltale signals of climate change — cause myriad public health concerns, from the acute and direct (e.g., natural disasters like flooding and heat waves) to the indirect yet equally devastating (e.g., respiratory and mental illnesses). While impacts like these are observable and well documented, existing research has not established a direct link between climate change and life ...

AMHERST, Mass. – Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb) kills upwards of 1.6 million people a year, making it one of the leading causes of death by an infectious agent worldwide—and that number is only growing larger. How, exactly, Mtb evades the immune system isn’t yet known, but a collaborative team of researchers from the University of Massachusetts Amherst and Seattle Children’s Research Institute recently discovered something surprising: prior exposure to a genus of bacteria called Mycobacterium seems to remodel the first-line defenders in the body’s immune system. Furthermore, how ...

Repeated failures to reproduce make fruit flies stressed and frustrated, which in turn makes them less resilient to other types of stress, Julia Ryvkin at Bar-Ilan University and colleagues report in the open-access journal PLOS Genetics, publishing January 18. Animals are motivated to take actions that improve their survival and reproduction through reward systems in the brain, but failure causes stress. The reward systems have been extensively studied, but less attention has been paid to how animals respond to failure. To investigate, researchers compared ...

Most people infected with the SARS-CoV-2 virus recover after the acute illness. However, a significant proportion of infected individuals develop long-lasting symptoms with a wide range of manifestations. The causes and disease mechanisms of Long Covid are still unknown, and there are no diagnostic tests or targeted treatments. Part of the immune system active for too long A team of researchers led by Onur Boyman, professor of immunology at the University of Zurich (UZH) and Director of the Department of Immunology at the University Hospital Zurich (USZ), has shown in a study that the complement system plays an important role in Long Covid. It is part of the innate immune system ...

JANUARY 18, 2024, NEW YORK – A Ludwig Cancer Research study has generated a granular portrait of how the cellular and molecular components of the blood vessels that feed brain metastases of melanoma and lung and breast cancers differ from those of healthy brain tissue, illuminating how they help shape the internal environment of tumors to support cancer growth and immune evasion. Led by Ludwig Lausanne’s Leire Bejarano and Johanna Joyce, researchers also developed a platform to identify potentially targetable vulnerabilities in the vasculature of brain metastases. They report in the current issue of Cancer ...

We tend to separate the brain and the muscle—the brain does the thinking; the muscle does the doing. The brain takes in complex information about the world and makes decisions, and the muscle merely executes. This has also shaped how we think about a single cell; some molecules within cells are seen as ‘thinkers’ that take in information about the chemical environment and decide what the cell needs to do for survival; separately, other molecules are seen as the ‘muscle,’ building structures needed for survival.   But a new study shows how the molecules that build structures, i.e, the muscle, can themselves do both the thinking and the doing. The ...

CHAPEL HILL, NC – University of North Carolina at Chapel Hill scientists created a new drug delivery system, called the Spatiotemporal On-Demand Patch (SOP), which can receive commands wirelessly from a smartphone or computer to schedule and trigger the release of drugs from individual microneedles. The patch’s thin, soft platform resembles a Band-Aid and was designed to enhance user comfort and convenience, since wearability is a crucial factor for chronically ill patients. The research team, led by Juan Song, PhD, professor of pharmacology ...

AUSTIN, Texas –– Artificial intelligence has become the Swiss Army knife of the business world, a universal tool for increasing sales, optimizing efficiency, and interacting with customers. But new research from Texas McCombs explores another purpose for AI in business: to contribute to the social good. It can do so by helping businesses better serve vulnerable consumers: anyone in the marketplace who experiences limited access to and control of resources. “AI is widely recognized for its operational and ...

Structural insights into a potent antimalarial drug candidate’s interaction with the malaria parasite Plasmodium falciparum have paved the way for drug-resistant malaria therapies, according to a new study by researchers at Weill Cornell Medicine and Van Andel Institute. The antimalarial molecule, TDI-8304, is one of a new class of experimental therapeutics that targets the proteasome, an essential, multiprotein complex in P. falciparum cells. Two years ago, the researchers showed in a preclinical study that TDI-8304 potently kills malaria parasites at multiple stages of their life cycle and ...

RICHMOND, Va. (Jan.  18, 2024) – New research from Virginia Commonwealth University fundamentally challenges the paradigm that business organizations should promote profit above all else. Christopher S. Reina, Ph.D., executive director of the VCU Institute for Transformative Leadership, lays out the foundation for transforming business to be much more people-centered and humanistic in “Humanistic Organizing: The Transformative Force of Mindful Organizational Communication.” ...

The quantum ground state of an acoustic wave of a certain frequency can be reached by completely cooling the system. In this way, the number of quantum particles, the so-called acoustic phonons, which cause disturbance to quantum measurements, can be reduced to almost zero and the gap between classical and quantum mechanics bridged. Over the past decade, major technological advances have been made, making it possible to put a wide variety of systems into this state. Mechanical vibrations oscillating between ...

Electrical deep brain stimulation (DBS) is a well-established method for treating disordered movement in Parkinson’s disease. However, implanting electrodes in a person’s brain is an invasive and imprecise way to stimulate nerve cells. Researchers report in ACS’ Nano Letters a new application for the technique, called magnetogenetics, that uses very small magnets to wirelessly trigger specific, gene-edited nerve cells in the brain. The treatment effectively relieved motor symptoms in mice without damaging surrounding ...
