Brain activity and repetitive behaviour

“Civilization advances by extending the number of important operations which we can perform without thinking of them.” In this quote, the philosopher A. Whitehead underlines the importance of automated low-level tasks when performing a complex and repetitive task. Tying shoelaces, writing, walking… our mind is relieved from the elementary actions […]

Advancing Gene Editing With New CRISPR/Cas9 Variant

Using a new variant to repair DNA will improve both safety and effectiveness of the much-touted CRISPR-Cas9 tool in genetic research, Michigan Medicine researchers say. Those two key problems – safety and efficacy – are what continue to hold CRISPR-Cas9 gene targeting back from its full clinical potential, explains co-senior […]

Resistance Pulse

In recent years, targeted therapies have cemented their place as some of the most important tools in cancer treatment. These medicines are designed to block specific signals that tumour cells use to grow and spread, while at the same time leaving normal cells unharmed. Targeted therapies can significantly extend patients’ […]

A novel approach to Parkinson's disease

When scientists study the neuronal mechanisms responsible for neurodegenerative diseases like Parkinson’s, they can open the door to promising new approaches to treating those diseases with drugs. But when a person with Parkinson's dies, looking at their brain reveals little about the cells inside and offers only a glimpse into […]

New DNA modification ‘signature’ discovered in zebrafish

Researchers at the Garvan Institute of Medical Research have uncovered a new form of DNA modification in the genome of zebrafish, a vertebrate animal that shares an evolutionary ancestor with humans ~400 million years ago. Dr Ozren Bogdanovic and his team discovered that unusually high levels of DNA repeats of […]

Clinical guidance for two rare immune conditions revealed

An international study co-led by researchers at the Garvan Institute of Medical Research has provided new guidance for the clinical treatment of two rare inherited immune disorders. Researchers combined global data on the two conditions, caused by variants of the genes CD27 and CD70, and diagnosed mostly in children. Their study revealed that […]

Novel Tool Deciphers Cells’ Energetic Code to Enhance Anticancer Therapies

Immunotherapies are a promising anticancer arsenal and work by mobilizing the immune system to recognize and destroy cancer cells. Currently, however, only a third of patients respond to immunotherapies, in part because the tumour environment can be hostile to immune cells, depriving them of their source of energy, which diminishes treatment […]

Scientists discover why the heart slows down at night

A consensus more than 90-years-old on the mechanisms which regulate the day-night rhythm in heart rate has been fundamentally challenged by an international team of scientists from Manchester, London, Milan, Maastricht, Trondheim and Montpellier. The vagus nerve – one of the nerves of the autonomic nervous system which supplies internal […]

Big data analysis suggests role of brain connectivity in epilepsy-related atrophy

An international study has found a link between the brain’s network connections and grey matter atrophy caused by certain types of epilepsy, a major step forward in our understanding of the disease. In neuroscience, it is becoming increasingly clear that the brain’s connectome is as important as its anatomy when […]

Vision Revision: Reversing Aging in Eye Cells

Scientists reverse age-related vision loss, glaucoma damage in mice. Harvard Medical School scientists have successfully restored vision in mice by turning back the clock on aged eye cells in the retina to recapture youthful gene function. The team’s work, described in Nature, represents the first demonstration that it may be possible […]

Researchers Unlock the Door to Tumor Microenvironment for CAR T Cells

The labyrinth of jumbled blood vessels in the tumour microenvironment remains one of the toughest blockades for cellular therapies to penetrate and treat solid tumours. Now, in a new study published online in Nature Cancer, Penn Medicine researchers found that combining chimeric antigen receptor (CAR) T cell therapy with a PAK4 […]

Common pipe alloy can form cancer-causing chemical in drinking water

Rusted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside. Chromium is a metal that occurs naturally in the soil and groundwater. Trace amounts of trivalent chromium eventually appear in the drinking […]

AI predicts which drug combinations kill cancer cells

When healthcare professionals treat patients suffering from advanced cancers, they usually need to use a combination of different therapies. In addition to cancer surgery, the patients are often treated with radiation therapy, medication, or both. Medication can be combined, with different drugs acting on different cancer cells. Combinatorial drug therapies […]

Telomere shortening protects against cancer

As time goes by, the tips of your chromosomes—called telomeres—become shorter. This process has long been viewed as an unwanted side-effect of ageing, but a recent study shows it is in fact good for you. “Telomeres protect the genetic material,” says Titia de Lange, Leon Hess Professor at Rockefeller. “The DNA […]

Sensor can detect scarred or fatty liver tissue

About 25 per cent of the U.S. population suffers from fatty liver disease, a condition that can lead to fibrosis of the liver and, eventually, liver failure. Currently, there is no easy way to diagnose either fatty liver disease or liver fibrosis. However, MIT engineers have now developed a diagnostic […]
