Scientists find a simpler way to make sensory hearing cells

Scientists from the USC Stem Cell laboratories of Neil Segil and Justin Ichida are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce sensory cells known as “hair cells,” due to their hair-like protrusions that sense sound waves. The study was published […]

Obesity is a significant contributor to early dementia

Aging sucks. Your entire body starts deteriorating and it’s sad. There is nothing good about aging. But probably the worst part is the decline of cognitive abilities. Losing the sharpness of your mind is truly heartbreaking, but millions and millions of people are facing the inevitability of dementia. However, scientists […]

Children begin to outsource their thinking at a very young age

Companies often outsource some of their activities. It means that some parts of their work are done by other organizations, typically where labour is cheaper or there are other incentives. But humans outsource some of their activities too. Scientists from the University of Queensland found that children begin outsourcing thinking […]

Scientists uncovered the mechanism how carcinogens cause cancer

Pretty much half of us is going to get cancer. This is part and parcel of our stressful lifestyle as well as aging. Some substances around us are very efficient in causing cancer. But why is that? Why some chemicals are able to cause cancer, which occurs when errors happen […]

Light-activated 'CRISPR' enables fast, precise gene editing and detection of DNA repair

In a series of experiments co-funded by the National Science Foundation, scientists at Johns Hopkins have used light as a trigger to make quick, precise cuts in the genomic material of human cancer cell lines. The researchers cut the DNA within seconds using a molecular scalpel known as CRISPR and were able to […]

Nuclear Softening Allows Cells to Move Into Dense Tissue, Encouraging Injury Repair

Using an enzyme inhibitor in meniscus cells, a Penn team was able to soften their nucleus and promote access to previously impassible areas. By softening a cell’s nucleus so that it can squeeze its way through dense connective tissues, a group of researchers believes they’ve demonstrated a new way to […]

Exercise can slow or prevent vision loss, UVA study suggest

Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests. A study from the University of Virginia School of Medicine found that exercise reduced the harmful overgrowth of blood vessels in the eyes of […]

Laser-welded sugar: Sweet way to 3D-print blood vessels

Powdered sugar is the special ingredient in a Rice University recipe for mimicking the body’s intricate, branching blood vessels in lab-grown tissues. In research published in the journal Nature Biomedical Engineering, Rice bioengineers showed they could keep densely packed cells alive for two weeks in relatively large constructs by creating complex blood vessel […]

New heart valve could transform open heart surgery for millions of patients globally

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's […]

Universal Gut Microbiome-Derived Signature Predicts Cirrhosis

Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease worldwide, affecting an estimated one-quarter of the global population. It is a progressive condition that, in worst cases, can lead to cirrhosis, liver cancer, liver failure and death. In a new paper published online in Cell Metabolism, […]

Genomes front and centre of rare disease diagnosis

Cambridge-led study discovers new genetic causes of rare diseases, potentially leading to improved diagnosis and better patient care. A research programme pioneering the use of whole genome sequencing in the NHS has diagnosed hundreds of patients and discovered new genetic causes of disease. Whole genome sequencing is the technology used […]

Circular RNA makes fruit flies live longer

Ribonucleic acid, or RNA, is part of our genetic code and present in every cell of our body. The best known form of RNA is a single linear strand, of which the function is well known and characterized. But there is also another type of RNA, so-called “circular RNA”, or […]

Immune Cells Infiltrating Tumors May Play Bigger Cancer Role Than Previously Thought

Most traditional cancer therapies target either the tumor cells themselves or indiscriminately kill any rapidly dividing cell. New findings by researchers at University of California San Diego School of Medicine indicate that manipulating macrophages, a type of immune cell found abundantly in the tissues surrounding a tumor, could also be […]

Why memory-forming neurons are vulnerable to Alzheimer's

When Alzheimer’s disease strikes, the entire brain doesn’t crumble at once. Instead, the mind unravels like grim clockwork, beginning with the telltale degradation of a group of brain cells in the entorhinal cortex. These so-called vulnerable neurons are responsible for shuttling experiences into memories. They are always the first to […]
