They’re among the most ruthless opponents for pediatric oncologists: brain tumors that can’t be surgically removed or that resist standard therapies. Doctors have limited weapons to fight them, contributing to why brain cancer is still the leading cause of cancer-related death in children. But some institutions are re-thinking their approach. […]

Running and lifting weights might be a crucial step in helping your body delay the effects of aging, but those exercises may be only part of the story. In a new article published in Psychological Bulletin, a University of Georgia researcher found that the type of activity you choose may also have […]

Neural crest cells — embryonic cells in vertebrates that travel throughout the body and generate many cell types — have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development. But the capacity of neural crest cells to […]

Yale Cancer Center scientists have built a powerful genomic research platform to study cervical cancer, a disease that often is untreatable if it progresses after surgery or primary chemo-radiation treatment. The work is described in a study published in the Proceedings of the National Academy of Sciences (PNAS). “We have identified […]

Scientists at the University of Virginia School of Medicine have discovered a strange new organelle inside our cells that helps to prevent cancer by ensuring that genetic material is sorted correctly as cells divide. The researchers have connected problems with the organelle (a subcellular structure) to a subset of breast cancer […]

Is it dangerous to have high blood pressure when exercising? “It depends”, is the answer from a newly published study. One important parameter used to give a prognosis or diagnosis in several conditions is blood pressure during exercise. A new study led by LiU scientist Kristofer Hedman shows that high […]

A study from McMaster has found a potential mechanism explaining why some people who take drugs to lower their cholesterol develop sore, aching muscles. The use of statin drugs to significantly lower cholesterol, and ultimately reduce the risk of cardiovascular disease, has become widespread and large-scale studies suggest that nearly […]

If you’re a human embryonic stem cell — and who among us hasn’t been — the G1 (“Gap 1”) phase of development is an important time. For the first few hours of this phase that occurs within the larger process of the cycle of cell division, you’re deliberating the nature […]

Zebrafish—striped fish a few centimeters long—have the ability to regrow up to 20 percent of their hearts after sustaining major damage. Now, Caltech scientists have discovered that embryonic cells from the hindbrain, called neural crest cells, migrate to the developing heart and form heart muscle in zebrafish and other species. […]

Researchers at Karolinska Institutet have followed children who have sought emergency care for wheezing during their first years of life and found specific biomarkers that can predict the need for asthma medication several years later. The study is published in the prestigious European Respiratory Journal. Today, biomarkers for asthma are […]

People with multiple sclerosis who can walk at a relatively normal speed and effectively process information are more likely to continue to participate in social activities, according to a new study by researchers at Karolinska Institutet in Sweden published in the Multiple Sclerosis Journal. The findings highlight the importance of […]

Could an animal’s personality and problem-solving skills help it to cope with environmental adversity? Cairns animal behaviourist, Dr Tasmin Rymer, is working with Australian native rats to identify the characteristics that make some individuals better able to cope and survive in damaged and changed environments than others. The James Cook […]
