Psoriasis – a common, chronic skin disease that affects over 100 million people worldwide. It is incurable, even though there are pretty effective techniques for managing the symptoms. However, now scientists from the University of Birmingham have discovered a protein, which could eventually lead to more effective therapies for many […]

Reporting in the academic journal Cancer Research, a group of Japanese researchers have devised an artificial intelligence (AI) system (called VGG16) that can identify different types of cancer cells comprising a single tumour, and successfully gauge their susceptibility to radiotherapy. “This study demonstrates rapid and accurate identification of radioresistant tumour […]

Incorporating genetic diversity into a mouse model of Alzheimer’s disease resulted in greater overlap with the genetic, molecular and clinical features of this pervasive human disease, according to a study funded by the National Institute on Aging (NIA), part of the National Institutes of Health. The study also suggests that […]

There is nothing fun about getting old. One of the worst things is deterioration of mental capacities, such as memory. As people get older, retention of new information typically declines, but there are ways to delay and slow down this process. Scientists from the University of Waterloo found that drawing […]

A team of Florida State University researchers has unlocked a decades-old mystery about how a critical cellular process is regulated and what that could mean for the future study of genetics. In cells, DNA and its associated material replicate at regular intervals, a process essential to all living organisms. This […]

An outstanding question in dermatology that researchers have studied for decades is: How do hair follicles emerge from a sea of seemingly uniform skin cells during embryonic development? New research findings from a Yale-led team offer answers to that question, which may lead to strategies for regenerating lost hair follicles […]

Scientists have identified a growth factor found in the kidneys that could minimise the diabetes-inducing effects of blood vessel damage. The findings come in the wake of recent data from Diabetes UK which revealed that almost 4.6 million people nationwide have either type 1 or type 2 diabetes.  Coupled with […]

Scientists in Anant Madabhushi’s computational imaging lab at Case Western Reserve University have started thinking outside the box—or in their case, looking outside the tumor. They’re hoping that this novel computerized approach represents a historic leap in diagnosing cancer using just routine CAT scans. If proven successful, it would be […]

Eye trauma or various infections often lead to impaired vision or even blindness. However, these conditions do not have such an effect in themselves – usually disability occurs due to scar tissue forming in cornea. This outer layer of the eye is transparent, but turns opaque due to scarring. Now […]

A series of studies conducted by teams led by Harvard Medical School systems biologists Allon Klein, Marc Kirschner and Sean Megason, as well as the work of teams led by Alexander Schier at Harvard University in collaboration with Aviv Regev at the Broad Institute of MIT-Harvard, have been featured as part of the “2018 Breakthrough of the […]

Of the many outstanding mysteries of neuroscience, the pathogenic origins of Alzheimer’s disease (AD) remain one of the most perplexing neurological puzzles. An estimated 5.7 million Americans are presently afflicted with the disease, which gradually ravages the aging brain, resulting in progressive loss of memory followed by other cognitive abilities. […]

Professor Matt Smalley, from Cardiff University’s European Cancer Stem Cell Research Institute, said: “There are 150 new cases of breast cancer diagnosed in the UK every day. To achieve better outcomes for people facing this disease, we need to better understand how it develops so we can improve therapies. “We […]

With the help of a new human embryonic stem cell line, researchers make initial strides toward treatment for the genetic mutation. Fragile X syndrome is the most common inherited cause of intellectual disability and autism and poses a significant burden to affected families. The syndrome gets its name because — […]

A group of genes that has been largely ignored by scientists could play critical roles in atherosclerosis (hardening of the arteries), inflammation, and likely obesity and other metabolic diseases, new research suggests.
