Keeping physically and mentally active in middle age may be tied to a lower risk of developing dementia decades later, according to a new study. Mental activities included reading, playing instruments, singing in a choir...

Researchers have identified a new gene whose variants cause hereditary childhood-onset osteoporosis. The gene defect was first found in two Finnish families.

Researchers have developed a device that can isolate individual cancer cells from patient blood samples.

Scientists report a new and improved method to detect chemical modifications to DNA. These modifications -- or 'epigenetic' marks -- help control gene expression and their aberrant distribution across the genome contribu...

Neuroscientists have used CRISPR/Cas9 genome editing technology to regulate genes in the rat brain. This technique paves the way for researchers to probe genetic influences on brain health and disease in model organisms ...

Scientists have discovered a new protein 'switch' that could stop the progression of blood-poisoning, or sepsis, and increase the chances of surviving the life-threatening disease.

A previously unknown messenger which alarms nearby cells when the immune system recognizes a bacterial or viral infection has been uncovered.

Researchers have identified one of the main mechanisms behind the repair of serious damage to the human DNA.

A 3D hydrogel is helping researchers to quickly screen hundreds of potential drugs for their ability to fight highly invasive cancers.

Syringes and hollow needles have been used to deliver medication for more than a century. However, the precise implementation of these devices depends on the operator, and it can be difficult to deliver medication to del...

The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future gene-editing technology. T...

Researchers have discovered a new and rare skeletal disease. They describe the molecular mechanism of the disease, in which small RNA molecules play a role that has never before been observed in a congenital human diseas...

If greenhouse gas emissions keep rising, a cloud feedback effect could lead to more than 14°C warming above the pre-industrial level

The programme Safe Fall- Safe Schools© establishes a methodology that is suitable for different ages of students, centred on progression by levels and types of fall (backwards, sideways and forwards), in which the child...

Partnered with machine learning, brain scans reveal how people understand objects in our world.

Physician-scientists have identified the cause of a devastating pediatric brain disorder paving the way for the first step in developing potential therapies for this rare neurodegenerative condition.

Nine patients have recently been cured of the Hepatitis C virus (HCV) following lifesaving heart transplants from deceased donors who were infected with the disease, according to a new study. The results highlight the po...

How can you efficiently change someone's mind? The art of debate has always seemed like black magic to me. You're not necessarily arguing for something you believe in--rather, you're carefully dissecting the logic of you...

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of su...

The quarks inside atoms move slower than the quarks inside free-floating protons and neutrons. But why?

(University of Pittsburgh) Per- and polyfluorinated alkyl substances (PFAS) are man-made chemicals that are useful in a variety of industries because of their durability, but do not naturally break down in the environmen...

A new study reports human fat cells have their own internal clocks and circadian rhythms which affect metabolic functions.
