Here’s the reason why lack of sleep is bad for your heart

It found that people who sleep fewer than 7 hours per night have lower blood levels of three physiological regulators, or microRNAs, which influence gene expression and play a key role in maintaining vascular health. The findings could potentially lead to new, non-invasive tests for sleep-deprived patients concerned about their health, the authors said. “This […]

Cancer: Compound found in broccoli, kale can suppress tumour growth

The body has its own mechanisms for fighting cancer, but sometimes they are too weak to suppress tumour growth. Now, scientists have found that broccoli, kale, and other cruciferous vegetables contain a compound that could reinvigorate one of these innate mechanisms. Researchers from Harvard Medical Schools Beth Israel Deaconess Medical Center in Boston, Massachusetts, saw […]

Low oxygen levels harm specific cells in the developing brain

Now, researchers at the Stanford University School of Medicine have identified a specific set of brain cells that are particularly susceptible to harm from low oxygen exposure in early development. This damage is congruent with brain abnormalities, particularly reduction in grey matter, seen among children who are born very prematurely. The researchers have also identified […]

Pregnant women with type 1 diabetes are at a high risk of preterm birth

  These are the findings from researchers at Karolinska Institutet and the Sahlgrenska Academy in Sweden, published in Annals of Internal Medicine. In a previous study published in The BMJ, the research group showed that pregnant women with type 1 diabetes were at an increased risk of having babies with heart defects. Now, a new […]

Turmeric compounds may help fight against stomach cancer, reveals study

Curcumin is widely used to impart colour and flavour to food, but scientists have discovered that this yellow powder derived from the roots of the turmeric plant (Curcuma longa) can also help prevent or combat stomach cancer. The study by researchers at the Federal University of São Paulo (UNIFESP) and the Federal University of Pará […]

Any kind of exercise can help benefit brain health in older adults, says study

Researchers from School of Kinesiology and Graduate Program in Neuroscience have demonstrated that bouts of aerobic exercise, as brief as 10 minutes, enhances cognitive function of older adults. They also found that these benefits could be realised by those previously encouraged not to exercise. The study, which included 17 older adults with an average age […]

Physical activity may help fight depression in older adults, suggest US study

The findings, published in the American Journal of Physiology–Cell Physiology, reveal that the underlying mechanisms which make us feel good when we exercise persist into old age and highlight the importance of staying active. “A previous study demonstrated these mechanisms in healthy young adults, however, it was unknown whether the muscle deterioration which accompanies aging […]

Gene editing tool may inadvertently raise cancer risk, caution scientists

Researchers from the Britain’s Cambridge University and Sweden’s Karolinska Institute said more research needs to be done to assess whether using CRISPR-Cas9 – a type of molecular “scissors” that make gene editing a possibility – might lead to the development of treatments that have added cancer risk. The team, led by Jussi Taipale at Cambridge, […]

Gene that regulates bone growth can also help in cognition

Gene that regulates bone growth can also help in cognition

A gene that regulates bone growth and muscle metabolism in mammals may take on an additional role as a promoter of brain maturation, cognition and learning in human and non-human primates, according to a new study led by neurobiologists at Harvard Medical School. Describing their findings in the Nov. 10 issue of Nature, researchers say […]

Breakthrough: Scientists attempt gene editing inside the human body, for the first time

Breakthrough: Scientists attempt gene editing inside the human body, for the first time

Scientists have tried editing a gene inside the body for the first time, in a bold attempt to tackle an incurable a disease by permanently changing a patient’s DNA. On Monday in California, Brian Madeux, a 44-year-old intravenously received billions of copies of a corrective gene and a genetic tool to cut his DNA in a […]
