Injuries to peripheral nerves –– tissues that transmit bioelectrical signals from the brain to the rest of the body ­­–– often result in chronic pain, neurologic disorders, paralysis or disability. Now, researchers have developed a stretchable conductive hydrogel that could someday be used to repair these types of nerves when […]

For many people, getting older can, unfortunately, mean an increased risk of illnesses, from cardiovascular disease to cancer. University of Michigan scientists are actively researching the biological underpinnings of ageing with the aim of developing interventions that could help people live longer, healthier lives. A paper in the journal Science Advances describes […]

A study led by researchers at WIMR has, for the first time, demonstrated how CD47 – a cell surface protein – drives biological dysfunctions in the body, such as decreased circulation and poor metabolic homeostasis, both of which worsen with age. Researchers hope developing therapies that target CD47 will significantly reduce […]

All life depends upon DNA repair and replication. In every human cell the essential ability to replicate and repair genomes depends upon the coordinated actions of the genome sequence. Flaws or mistakes in repair and cell cycle regulation can lead to defects in the structure of the DNA and can […]

Individuals with traumatic brain injuries, or TBIs, frequently experience the shrinking or atrophying of brain tissue near where the injury occurred, causing additional damage beyond the original harm. If this can be prevented, many could function in the future who cannot now. Few therapies currently exist to treat TBIs, but […]

Driven by a machine learning algorithm, the closed-loop biohybrid device maintained a set membrane voltage in human stem cells for 10 hours. In an impressive proof-of-concept demonstration, an interdisciplinary team of scientists has developed a bioelectronic system driven by a machine learning algorithm that can shift the membrane voltage in […]

People with pale coloured melanomas are more likely to have a gene mutation associated with albinism, University of Queensland research has found. Study lead author Dr Jenna Rayner said albinism, a rare genetic disorder affecting one in 10,000 people, prevented brown pigment from being synthesised in the body and led to fair hair and […]

Biology textbooks may need to be re-written, with scientists finding a new piece of DNA essential to forming male sex organs in mice. An international research collaboration with The University of Queensland found the Y-chromosome gene that makes mice male is made up of two different DNA parts, not one, as scientists […]

A new study published in The Lancet, led by a Liverpool based research collaboration, has identified the first effective treatment for a rare genetic condition known as Alkaptonuria (AKU). The aim of the study, led by Professor Lakshminarayan Ranganath and Professor James Gallagher of the University of Liverpool’s Institute of Life Course and Medical […]

Long-term memory is controlled by protein synthesis in inhibitory cells, an international team at UdeM, McGill University and the University of Haifa finds. A Canadian-Israeli research team involving scientists at Université de Montréal has discovered that during memory consolidation, there are at least two distinct processes taking place in two […]

The risk for melanoma, the most deadly skin cancer, can be estimated long before the detection of any suspicious moles, according to a UC San Francisco scientist who led a new study to detect DNA mutations in individual skin cells. Skin damage from the sun builds up over time but […]

Microplastic fibre pollution in the ocean affects larval lobsters at each stage of their development, according to new research. A U.S. National Science Foundation-funded study published in the Marine Pollution Bulletin reports that the fibres affect the animals' feeding and respiration, and they could prevent some larvae from reaching adulthood. “In […]

A recent study by researchers at McGill University has identified polycystic ovary syndrome (PCOS) is an independent risk factor for gestational diabetes and hypertensive disorders of pregnancy. The condition, known to lead to multiple reproductive complications, including infertility, affects 1 in 10 women of childbearing age. PCOS was already known […]

Researchers from The Liverpool Centre for Cardiovascular Science have contributed to a new study, published in The European Heart Journal, that shows people with atrial fibrillation (AF) have a reduced risk of dementia if they undergo a procedure called catheter ablation to restore the normal rhythm of their heart. AF is the […]

In 2015, researchers began noticing that a drug used to treat Type 2 diabetes, empagliflozin, came with the added benefit of decreasing hospitalization for heart failure and death from cardiovascular causes in those patients. “It was very unexpected, because this drug is targeted and marketed for Type 2 diabetes, not […]

Stopping the cannibalistic behavior of a well-studied enzyme could be the key to new drugs to fight age-related diseases, according to a new study published online in Nature Cell Biology. For the first time, researchers in the Perelman School of Medicine at the University of Pennsylvania show how the self-eating cellular […]

The gut’s microbiome — a complex, dense mixture of bacteria, fungi, and other microbes — plays an integral role in human health. A new Yale study reveals just how early the microbiome is formed and begins delivering this benefit. For the first time, Yale scientists report that components of the […]

Astrocytes with the APOE4 gene variant show deficits of a key cellular function, but overexpressing the gene PICALM overcame the defect. In a new study, a team of scientists based at The Picower Institute for Learning and Memory at MIT and the Whitehead Institute for Biomedical Research reveals evidence showing that […]

Imaging techniques could replace the need for invasive tissue biopsies in helping rapidly determine whether cancer treatments are working effectively, according to researchers at the University of Cambridge. In a study published in the journal Cancer Cell, researchers at the Cancer Research UK (CRUK) Cambridge Institute have shown how a new […]

Being able to talk in several languages is an important skill to have. The world is shrinking and if you want to do business or build a career in other international organizations you will have to speak at least one foreign language. But is it true that younger people pick […]

If you want to know how old the tree was, you have to count the rings on its stomp. That, of course, requires you to cut down the tree or at least core it – drill a deep hole into it. But how can you know the age of the […]

A recent study published in the journal Nature Medicine, led by researchers James Riley, PhD, a professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, and Todd Allen, PhD, a professor of Medicine at Harvard Medical School and Group Leader at the Ragon Institute of MGH, MIT and […]

Ambitious efforts at the UVA Cancer Center to improve care delivered to patients with cancer that has spread to the brain have yielded important insights and tools that can benefit other hospitals, a new publication reports. The tools include the first set of metrics to assess care provided for these […]

The team of biomedical researchers at the Center for Computational Imaging and Personalized Diagnostics (CCIPD) has tackled various aspects of lung cancer, breast cancer, colon cancer and more since the centre was launched at Case Western Reserve University in 2012 by bioengineering pioneer Anant Madabhushi. Now, Madabhushi’s lab and partners in the Perelman […]

Every living human is controlled by an internal “clock” which drives our circadian rhythm – the natural internal process that regulates our sleep-wake cycle during a 24-hour period. This internal clock controls most of our body processes over this period, including our sleep cycle, digestion, metabolism, appetite and immunity. External […]

The number of mutations that can contribute to ageing may be significantly higher than previously believed, according to new research on fruit flies. The study by scientists at Linköping University supports a new theory about the type of mutation that can lie behind ageing. The results have been published in […]
