Researchers identified a novel mechanism by which skin cancer resists immunotherapy

Scientists describe how an immune cell recruited to the tumor induces the programmed suicide, or apoptosis, of the killer T cells harnessed by many immunotherapies. They also identified the specific molecular interaction responsible for this effect. That interaction — between a protein on T cells known as FAS and its ligand produced by suppressive immune cells — could be disrupted to improve the efficacy of cancer immunotherapies.

Scientists have just unveiled silicon probes for HD recording of neural activities

The more detail we can get on the inner workings of the brain, the better our chances of understanding and treating it, and scientists have just unveiled a new high-definition recording probe that’s thinner than a human hair.

Breakthrough research suggests potential treatment for autism, intellectual disability

A research team has identified the pathological mechanism for a certain type of autism and intellectual disability by creating a genetically modified mouse. They are hopeful it could eventually lead to a therapeutic fix.

Researchers have identified a peptide that could lead to the early detection of Alzheimer’s disease

Researchers have identified a peptide that could lead to the early detection of Alzheimer’s disease (AD). The discovery may also provide a means of homing drugs to diseased areas of the brain to treat AD, Parkinson’s disease, as well as glioblastoma, brain injuries and stroke.

New research reveals mechanisms through which low-calorie diets can reverse type 2 diabetes

Links between type 2 diabetes and diet have been well established – it is triggered when the body can no longer manage its blood glucose levels – but this latest study adds to growing evidence that the condition could be reversed in some cases.

Scientists exploit rhythm of DNA replication to kill cancer cells

Human cells divide and create new cells throughout life. In this process, a steady — even rhythmic — supply of DNA building blocks is needed to create new DNA. Now researchers have shown exactly how human cells regulate this process so it does not fail and cause illness. The researchers also show how they can manipulate the rhythm and suggest how this can be used in the future to kill cancer cells.

The way fruit flies identify similarities between odours offers a new approach for similarity search algorithms

Scientists have discovered that the fruit fly brain has an elegant and efficient method of performing similarity searches. For flies, it helps them identify odors that are most similar to those they’ve encountered before, so they know how to behave in response to the odor, such as to approach or avoid it

Researchers have incorporated circuits into fabric, opening up new possibilities for wearable electronics

Researchers have successfully incorporated washable, stretchable and breathable electronic circuits into fabric, opening up new possibilities for smart textiles and wearable electronics. The circuits were made with cheap, safe and environmentally friendly inks, and printed using conventional inkjet printing techniques.

Scientists unravelled the causes of blood vessel leakage in severe dengue

A protein secreted by cells infected with dengue virus can cause dangerous leakage of fluid from blood vessels, and new research supports a primary underlying mechanism: disruption of a molecular barrier that lines the vessels.

Scientists have discovered an entirely new type of eye cells in deep-sea fishes

It turns out this fish has an eye cell that works differently from any other light-sensing cell researchers have encountered – and it might even be more efficient. You may have heard that the vision receptors in most vertebrate retinas, including our own, have two different photoreceptor (or light-sensing) cell types called cones and rods.
