Brain tumors occur often in kids with common genetic syndrome

The frequency of brain tumors has been underestimated in children with the common genetic syndrome neurofibromatosis type 1 (NF1), according to a new study. This disorder is characterized by birthmarks on the skin and benign nerve tumors that develop in or on the skin. Brain tumors also are known to […]

New Study Offers Hope of Recovery from Spinal Cord Injury

Spinal cord injury or damage causes permanent changes in strength, sensation and other body functions. Hope of recuperation is slim to none. Now a new Tel Aviv University study finds the intravenous injection of a potent enzyme, just hours after an accident, has the potential to diminish a cascade of pathological events […]

Ant study sheds light on the evolution of workers and queens

Worker ants, despite their diligence, seldom encounter opportunities for social mobility. In many species, individuals adhere to strict caste roles: queens lay eggs and workers take care of almost everything else, including offspring. In a new study, published in Science, Rockefeller scientists describe the molecular mechanisms controlling this division of labor. “We […]

Genes drive ageing, making normal processes damaging

Ageing in worms mainly results from the direct action of genes and not from random wear and tear or loss of function, and the same is likely to be true in humans, according to research by UCL, Lancaster University and Queen Mary University of London scientists. The study, published in Current […]

Artificial intelligence model “learns” from patient data to make cancer treatment less toxic

MIT researchers are employing novel machine-learning techniques to improve the quality of life for patients by reducing toxic chemotherapy and radiotherapy dosing for glioblastoma, the most aggressive form of brain cancer. Glioblastoma is a malignant tumor that appears in the brain or spinal cord, and prognosis for adults is no […]

Key difference in how stem cells act when stressed versus when at rest revealed

Researchers from the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and Jonsson Comprehensive Cancer Center have discovered an important distinction in how blood-forming stem cells are supported by their micro-environments during rest and after injury. The body appears to switch the type of cell that produces […]

Study: Alzheimer's drug may stop disease if used before symptoms develop

About 50 percent of people who reach the age of 85 will develop Alzheimer’s disease. Most will die within about five years of exhibiting the hallmark symptoms of the disease – severe memory loss and a precipitous decline in cognitive function. But the molecular processes that lead to the disease […]

Genetic Mutations of Appendix Cancer Identified, May Impact Treatment

The rarity of appendix cancer, accounting for less than 1 percent of tumors that originate in the gastrointestinal tract, and the lack of scientific data for this disease means that current treatment guidelines recommend applying therapies to people with appendix cancer that are intended for those with colon cancer. To […]

The bladder can regenerate like nobody’s business and now we know why

The bladder is a master at self-repair. When damaged by infection or injury, the organ can mend itself quickly, calling upon specialized cells in its lining to repair tissue and restore a barrier against harmful materials concentrated in urine. But a new study in mice from researchers at the University […]

Scientists discover cause of aging-related disease in mice, then reverse its symptoms

In a study published in Aging Cell, researchers at the University of Wisconsin–Madison show that mice making too much of a human protein called AT-1 show signs of early aging and premature death, which are also symptoms of the human disorder progeria. Researchers were able to reverse the signs of accelerated […]

Sensor could help doctors select effective cancer therapy

MIT chemical engineers have developed a new sensor that lets them see inside cancer cells and determine whether the cells are responding to a particular type of chemotherapy drug. The sensors, which detect hydrogen peroxide inside human cells, could help researchers identify new cancer drugs that boost levels of hydrogen […]

Research reveals molecular details of sperm-egg fusion

The fusion of a sperm cell with an egg cell is the very first step in the process that leads to new individuals in sexually reproducing species. Fundamental as this process may be, scientists are only now beginning to understand the complexities of how it works. In a paper published […]

Created Line of Spinal Cord Neural Stem Cells Shows Diverse Promise

Researchers at University of California San Diego School of Medicine report that they have successfully created spinal cord neural stem cells (NSCs) from human pluripotent stem cells (hPSCs) that differentiate into a diverse population of cells capable of dispersing throughout the spinal cord and can be maintained for long periods […]

Koala virus could explain why humans have ‘junk’ DNA

A koala virus could help researchers explain millions of years of accumulated ‘junk’ DNA in the human genome. An international team of researchers – including scientists from The University of Queensland – is studying a virus infecting koalas in the hope it could demonstrate how viruses have altered the DNA […]

Cellular communication system in mice helps control female fertility

When Joan Jorgensen was an undergraduate at the University of Wisconsin–Madison, her roommate confided that she had just one period before going through menopause in high school. Doctors told Jorgensen’s roommate that she would never have biological children. “This is devastating news at any age, let alone a high school […]

Nanoparticles improve tumor treatment in mice

In the treatment of cancer, chemotherapy is a cleaver, not a scalpel. By attacking rapidly dividing cells, chemotherapy effectively fights tumors, but it also ravages healthy cells in the gut, bone marrow, the scalp and other organs, leading to severe side effects. These toxic chemicals save lives, but at a […]

Striking a Balance Between Immunity and Inflammation

Hookworms infect nearly 430 million people in the world, mostly in countries where sanitation is poor, and people often walk barefoot. The body’s immune system is critical to attacking the hookworm, resulting in damage to the body’s tissues. But just how this damage takes place — and what helps repair […]

Key aspects of human cell ageing reversed by new compounds

Key aspects of the ageing of human cells can be reversed by new compounds developed at the University of Exeter, research shows. In a laboratory study of endothelial cells – which line the inside of blood vessels – researchers tested compounds designed to target mitochondria (the “power stations” of cells). In […]

Team Finds Correlation Between Genetics and Obesity Is Modified by Diet

A correlation between obesity and genetics has been found to be modified by diet, according to a scientific paper in the American Journal of Clinical Nutrition. A research group led by a U.S. Department of Agriculture (USDA) scientist found that a specific gene—APOA2—can result in a higher body mass index (BMI). […]

A breath test for early-stage Parkinson’s

Symptoms of Parkinson’s disease include tremor, loss of smell and neuropsychiatric problems. However, many people aren’t diagnosed until their disease is well-advanced, which could limit their treatment options. Now, researchers have tested a sensor to detect early-stage Parkinson’s disease from the breath of patients. They report their results in ACS Chemical […]

Protein affected by rare Parkinson’s mutation may lurk behind many cases of the disease

Mutations in the gene LRRK2 have been linked to about three percent of Parkinson’s disease cases. Researchers have now found evidence that the activity of LRRK2 protein might be affected in many more patients with Parkinson’s disease, even when the LRRK2 gene itself is not mutated. The study was published […]

No Mutation Needed: New Treatments Being Developed for a Small Group of Parkinson’s Patients May Work for Most People with the Disease

A gene linked to 3 to 4 percent of people with Parkinson’s disease could play an important role in most, if not all, people with the disease, according to new study findings from the University of Pittsburgh School of Medicine and UPMC. The gene, called LLRK2, was previously thought to only cause […]

Learning arithmetic refines the primal brain system for representing quantity

A wildebeest knows when it is outnumbered by a pack of hungry hyenas, thanks to an imprecise, primal brain function called the Approximate Number System, or ANS. Animals have it and human babies are born with it. Scientists have long believed that human’s ability to solve symbolic math problems such […]
