The molecule that could alleviate stroke-related brain injury

2024-07-10

A newly developed molecule, LK-2, could inform new therapies for stroke-related brain injury, finds scientists at The Hospital for Sick Children (SickKids). An ischemic stroke occurs when blood flow to a part of the brain is interrupted, depriving the brain cells of oxygen and nutrients. Without timely treatment, brain cells can die, resulting in permanent damage to the brain and its functions. Stroke is one of the leading causes of death and disability worldwide, affecting millions every year. An international study published in Nature co-led by Dr. Lu-Yang Wang, a Senior Scientist in the ...

Scientists discover a cause of lupus and a possible way to reverse it

2024-07-10

· Lupus is an autoimmune disease affecting more than 1.5 million people in the U.S. · Until now, the causes of this disease remained unclear · Scientists are working to expand research into novel treatment CHICAGO --- Northwestern Medicine and Brigham and Women’s Hospital scientists have discovered a molecular defect that promotes the pathologic immune response in systemic lupus erythematosus (known as lupus) and show that reversing this defect may potentially reverse the disease. Lupus affects more than 1.5 million ...

Few U.S. adults use nicotine pouches, study finds

2024-07-10

A new study found that the prevalence of nicotine pouch use was low in U.S. adults despite a 641% increase in sales of the products between 2019 and 2022. Researchers say the findings raise questions about who is using the millions of nicotine pouches sold in the U.S. and why. Nicotine pouches, a new commercial tobacco product, contain a crystalline powder with nicotine, flavorings (including fruit, mint or candy) and other additives. They do not cause respiratory harm and are perceived by some as an alternative to help adults who smoke tobacco quit. ...

Surprise discovery with big scientific potential

2024-07-10

An unexpected find has enabled important progress to be made in the battle against harmful bacteria. An international team of researchers, led by Professor Peter Fineran from the University of Otago, investigated a particular protein used by bacteria-infecting viruses, known as phages. Research into this microscopic arms race between bacteria and phages is important as it can lead to alternatives to antibiotics. Published in prestigious international journal Nature, the study analysed a protein phages use when deploying anti-CRISPR, their method of blocking the CRISPR–Cas immune system of bacteria. Lead ...

The plague may have caused the downfall of the Stone Age farmers

2024-07-10

Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows. In the 14th century Europe, the plague ravaged the population during the so-called 'Black Death,' claiming the lives of nearly a third of the population. But the plague arrived in Scandinavia several thousand years earlier, and despite several theories suggesting otherwise, the plague might have caused an epidemic, according to new research from ...

When there’s money to lose, phone usage while driving drops

2024-07-10

PHILADELPHIA— To make someone put their phone down while driving, show them the money—with a catch, according to new research published in JAMA Open. When a group of auto insurance customers were tempted with a cash incentive—and regular feedback letting the driver know how they were doing compared to other drivers trying to reduce their phone time—handheld phone use dropped significantly, a team at the Perelman School of Medicine at the University of Pennsylvania found. The researchers examined several different strategies ...

Astronomers find missing link in massive black hole formation

2024-07-10

Omega Centauri is a spectacular collection of 10 million stars, visible as a smudge in the night sky from Southern latitudes. Through a small telescope, it looks no different from other so-called globular clusters; a spherical stellar collection so dense towards the center that it becomes impossible to distinguish individual stars. But a new study, led by researchers from the University of Utah and the Max Planck Institute for Astronomy, confirms what astronomers had argued about for over a decade: Omega Centauri contains a central black hole. The black hole appears to be the missing link between its stellar ...

Researchers build first-ever molecular atlas of blood vessel pathways in the human brain, across early brain development, adulthood and disease

2024-07-10

An international consortium of researchers led by University Health Network (UHN) in Toronto and University of Zurich have built the first-ever molecular atlas of the human brain vasculature at single-cell resolution, spanning from early development to adulthood and through disease stages such as brain tumours and brain vascular malformations. The international consortium includes research teams from UHN’s Krembil Brain Institute, Donald K. Johnson Eye Institute, Toronto General Hospital Research Institute and Princess Margaret Cancer Centre, the University of Toronto’s Donnelly Centre, Mount Sinai Hospital’s Lunenfeld-Tanenbaum ...

Antiferromagnetic phase transition observed in fermionic Hubbard quantum simulator

2024-07-10

In a study published online in Nature, a research team led by Prof. PAN Jianwei, Prof. CHEN Yuao, and Prof. YAO Xingcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM). This study highlights the advantages of quantum simulation. It marks an important first step towards obtaining the low-temperature phase diagram of the FHM and understanding the role of quantum magnetism in the mechanism of high-temperature ...

A drug that lowers blood lipids could help treat the world’s most common liver disease

2024-07-10

The University of Barcelona has led a study that suggests using the drug known as pemafibrate to treat liver disease associated with metabolic disorders, the most common liver pathology in the world, which affects one in four people. The drug has long been marketed in Japan for another use: improving blood lipid levels in patients with hyperlipidaemia, a common condition in diabetics. Now, however, it could help address this serious liver disease, which still has no specific treatment. The study, carried out on laboratory animal models and published in the journal Biomedicine & Pharmacotherapy, was conducted by a team led by Professor Juan ...
