New clues to a long-pursued drug target in cancer may reside within immune cells, researchers at the University of Michigan Rogel Cancer Center have discovered. The findings, which appear in Nature Immunology, not only shed new light on cancer immunology, they also suggest clinical trials related to this key target — an interaction that […]

Scientists have genetically engineered immune cells, called myeloid cells, to precisely deliver an anticancer signal to organs where cancer may spread. In a study of mice, treatment with the engineered cells shrank tumors and prevented the cancer from spreading to other parts of the body. The study, led by scientists […]

Researchers at the National Institutes of Health (NIH) have discovered specific regions within the DNA of neurons that accumulate a certain type of damage (called single-strand breaks or SSBs). This accumulation of SSBs appears to be unique to neurons, and it challenges what is generally understood about the cause of […]

A recent study published in JCI found that a neutrophil’s endoplasmic reticulum, the organelle that normally makes proteins in the cell, becomes stressed in the autoimmune disorder lupus. This stress activates a molecule called IRE1α, which appears to play a critical role in lupus pathogenesis in mice. A multidisciplinary research group at the University […]

To prepare codes for the architecture and scale of […]

Two papers by University at Buffalo researchers reveal important new findings as to how regeneration of myelin in multiple sclerosis fails and, potentially, more efficient ways to treat it. The findings include the first demonstration that an existing drug, currently being studied as a cancer therapy, can alter key signalling […]

Epileptics, listen up: imagine being able to have a “weather forecast for your brain,” a way to get advance of the onset of your next seizure, thanks to a microchip planted under your scalp. Science fiction, you think? Not for two researchers at the Centre hospitalier de l’Université de Montréal […]

New research provides insights into the process of diffusion in living systems, with implications from novel active coatings to understanding how pathogens are cleared from lungs. A drop of food colouring slowly spreading in a glass of water is driven by a process known as diffusion. While the mathematics of […]

A new study led by University of Wisconsin–Madison School of Veterinary Medicine professor Erin Lashnits shows evidence of Bartonella infection in the blood of people with schizophrenia and schizoaffective disorder. “Researchers have been looking at the connection between bacterial infection and neuropsychiatric disease for some time,” Lashnits says in a news release by North Carolina […]

Excessive fat accumulation in the liver can lead to serious medical problems, including liver failure. Thus, understanding the distribution of lipids within the liver is a critical step in diagnosing fatty liver diseases. A team of researchers at Tokyo University of Science has now shown that near-infrared hyperspectral imaging permits […]

A large study of people living on five continents, led by researchers at McMaster University and the University of Toronto, has found a diet high in poor quality carbohydrates leads to a higher risk of heart attacks, strokes, and death. The higher risks of a diet high in poor quality […]

Graybiel lab identifies genes linked to abnormal repetitive behaviors often seen in models of addiction and schizophrenia. Extreme repetitive behaviors such as hand-flapping, body-rocking, skin-picking, and sniffing are common to a number of brain disorders including autism, schizophrenia, Huntington’s disease, and drug addiction. These behaviors, termed stereotypies, are also apparent in animal models […]

Cold Spring Harbor Laboratory (CSHL) President and CEO Bruce Stillman have been dissecting DNA replication, a critical step in cell division, since the 1980s. His lab studies how Origin Recognition Complexes—ORCs—coordinate DNA duplication. They discovered how our cells assemble and disassemble ORCs during the cell division cycle. One ORC protein is sequestered […]

‘We noticed that the patient monitoring processes in hospitals are inefficient. They also lack digital solutions and generate unnecessary manual and administrative tasks for the overworked nurses and doctors.’ says Miklós Knebel. Knebel and Péter Dános participated in a project run by EIT Digital Master School in which students designed a new type […]

Newborn babies with indicators of alcohol in their stool are more likely to face behavioral difficulties later in childhood, according to new study from a team of multi-disciplinary researchers at Case Western Reserve University.
