Maytal Saar-Tsechansky was standing a few meters from Israeli Prime Minister Yitzhak Rabin in 1995, when he was assassinated by a right-wing extremist in Tel Aviv. “At the time, Rabin was promoting peace with the Palestinians,” says Saar-Tsechansky, professor of information, risk, and operations management and the Mary John and Ralph Spence Centennial Professor at Texas McCombs. “The assassination was the result of a lot of incitement, of some people claiming that he was the enemy of the people.” Although she typically studies artificial intelligence, the traumatic incident planted a seed for a different interest: how to ease political divisions. She began ...

A common antihistamine may offer hope for patients with a rare genetic disease that can lead to severe liver damage and ultimately require transplantation, according to new research from Rutgers Health. The study in Cellular and Molecular Gastroenterology and Hepatology found that chlorcyclizine, a decades-old allergy medication, could potentially treat erythropoietic protoporphyria (EPP), a condition that creates extreme skin light sensitivity and can produce toxic levels of protoporphyrin in the liver, bone marrow, red cells, and plasma. "There is an unmet need for these patients," said Bishr Omary, senior ...

In patients with high-risk HER2-positive breast cancer, post-surgery, or adjuvant, treatment with trastuzumab emtansine (T-DM1) reduced the long-term risk of death or invasive disease by 46% and improved survival compared to trastuzumab alone, according to the final results of the phase 3 KATHERINE clinical trial led by researchers from the University of Pittsburgh and UPMC Hillman Cancer Center.  The findings, published today in the New England Journal of Medicine (NEJM), provide long-term evidence that T-DM1 is an effective adjuvant treatment for this population of breast ...

MINNEAPOLIS — People who eat more red meat, especially processed red meat like bacon, sausage and bologna, are more likely to have a higher risk of cognitive decline and dementia when compared to those who eat very little red meat, according to a study published in the January 15, 2025, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Red meat is high in saturated fat and has been shown in previous studies to increase the risk of type 2 diabetes and heart disease, which are both linked to reduced brain health,” said ...

A new paper by a team of Concordia researchers from the departments of Biology and Physics proposes a novel method of fighting cancer tumours that uses ultrasound-guided microbubbles — a technology already widely used in medical imaging and drug delivery. Writing in the journal Frontiers in Immunology, the researchers describe a process that uses ultrasound to modify the behaviour of cancer-fighting T cells by increasing their cell permeability. They examined how this can influence the release of more than 90 kinds of cytokines, a type of signalling molecule crucial for immune response. The researchers targeted freshly isolated human immune cells with tightly ...

CAMBRIDGE, MA — With a more efficient method for artificial pollination, farmers in the future could grow fruits and vegetables inside multilevel warehouses, boosting yields while mitigating some of agriculture’s harmful impacts on the environment. To help make this idea a reality, MIT researchers are developing robotic insects that could someday swarm out of mechanical hives to rapidly perform precise pollination. However, even the best bug-sized robots are no match for natural pollinators like bees when it comes to endurance, speed, and maneuverability. Now, inspired by the anatomy of these natural pollinators, the researchers ...

Researchers have demonstrated new wearable technologies that both generate electricity from human movement and improve the comfort of the technology for the people wearing them. The work stems from an advanced understanding of materials that increase comfort in textiles and produce electricity when they rub against another surface. At issue are molecules called amphiphiles, which are often used in consumer products to reduce friction against human skin. For example, amphiphiles are often incorporated into diapers to prevent chafing. “We set out to develop a model that would give us ...

Most treatments being pursued today to protect against Alzheimer’s disease focus on amyloid plaques and tau tangles that accumulate in the brain, but new research from Mass General Brigham and Washington University School of Medicine in St. Louis points to a novel—and noble—approach: using Xenon gas. The study found that Xenon gas inhalation suppressed neuroinflammation, reduced brain atrophy, and increased protective neuronal states in mouse models of Alzheimer’s disease. Results are published in Science Translational Medicine, and a phase 1 clinical trial of the treatment in healthy volunteers will begin in early 2025.   “It ...

The snow leopard (Panthera uncia) is a large feline unique to the Qinghai-Tibet Plateau and its surrounding areas. As the apex predator in the region, the snow leopard plays a crucial role in maintaining ecological stability. Its unique characteristics, coupled with its striking appearance, have made it a flagship species for conservation efforts aimed at protecting the ecosystem of the Qinghai-Tibet Plateau. Unfortunately, few snow leopard fossils have been found in the Qinghai-Tibet Plateau region, particularly fossils from the Quaternary period. As a result, it’s unclear how snow leopards evolved their specialized adaptations to this environment. On the one hand, molecular ...

According to the United Nations, soil salinization affects between 20% and 40% of arable land globally, with human activity and climate change – especially rising sea levels – largely responsible for this process. While the human body needs sodium to function, this is not the case for most plants. In fact, excess salt around plants’ roots gradually blocks their access to water, stunting their growth, poisoning them and hastening their death. Ten million hectares of farmland are destroyed by soil salinization every year, posing a threat to global food security. Scientists at EPFL, ...
