The worldwide map of dementia: Scientists reveal the memory-robbing disorder has skyrocketed by 117% over just 26 years as the global population continues to live longer Experts warn rates will double from 43.8million in 2016 to 100million by 2050 Turkey has the most cases, followed by Brazil, and Nigeria and Ghana the least  As well

When penis enlargement goes wrong: Scientists reveal the dangers of girth-increasing procedures which can cause gangrene, deformity and other ‘devastating complications’ A study of 11 men by California scientists revealed horrifying complications One 21-year-old injected his own penis with silicone and it became infected While a 48-year-old had fat injected into his member but it

It’s a common expression to say that your brain is full. Although the brain doesn’t literally fill up, in recent years researchers have discovered that the brain does sometimes push out old memories in order to take up new ones. Now, a team at Scripps Research has shown for the first time the physiological mechanism

Using technology similar to the type that powers facial and speech recognition on a smartphone, researchers at the University of North Carolina Lineberger Comprehensive Cancer Center have trained a computer to analyze breast cancer images and then classify the tumors with high accuracy. In a study published in the journal NPJ Breast Cancer, researchers reported

The emerging technology of sonogenetics—a technique where cells are controlled by sound—offers the potential to one day replace pharmaceutical drugs or invasive surgical treatments for neurological conditions like epilepsy, Parkinson’s disease or posttraumatic stress disorder. The Salk Institute scientist who pioneered the idea of using ultrasonic waves to stimulate neurons and coined the term “sonogenetics”

A bump to the head from slipping on the stairs, falling off a skateboard, or running into an open cupboard door has long been seen as a temporary injury, something resolved with a little rest. But a growing body of research suggests that, for some people, even concussions that seem mild can have serious, long-lasting

When it’s a significant injury, not just a hot pizza, that damages your tongue and taste buds, you appear to need a cell type best known for its inflammation-promoting skills to help restore your sense of taste. The intricate system that enables us to savor that pizza is daily mildly traumatized by the foods we

Simple blood and saliva tests that cost just £40 could help prevent heart attacks, scientists say Major study proves that scientists can identify people at risk of a heart attack  Scientists found DNA testing can be used to spot those with increased risk Currently more than 190,000 people suffer a heart attack in the UK each year

In the United States, over 100 million people are living with diabetes and prediabetes. Type 2 diabetes is a chronic condition requiring lifelong management; the disease impacts a number of systems in the body. As scientists spend increasing amounts of time investigating diabetes and its effects, they are discovering relationships with various other conditions. For

How we are suffering from choice OVERLOAD: Study reveals ‘lazy’ human brains give up trying to decide from more than 15 menu, film or grocery options The brain has to weigh up whether the effort is worth what it will get in return And as the number of options increases, so does the amount of

Using a genetic technique that allows certain neurons in the brain to be switched on or off, UCLA scientists reversed a sensory impairment in mice with symptoms of autism, enabling them to learn a sensory task as quickly as healthy mice. The findings, which appear in the journal Nature Neuroscience, offer an intriguing glimpse of

Hair loss affects millions of people, globally. For some, it is of little concern, but for others, it can impact both self-esteem and confidence. For these people, finding a way to regrow hair as quickly as possible is important. The causes of hair loss are very varied; they can include genetic factors, long-term stress, aging,

Researchers at St. Jude Children’s Research Hospital have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth. The analysis of thousands of brain cells isolated from mice offers researchers a high-resolution map that enables scientists to view the detailed genomic changes

A study led by Boston Children’s Hospital and the National Institute of Mental Health (NIMH) may open up new opportunities for treating neuropathic pain, a difficult-to-treat type of chronic pain due to damage to the nervous system that can make the lightest touch intensely painful. In a report today in Nature, scientists led by Zhigang

An experimental cancer vaccine that boosts the immune system’s ability to fight cancers could work in tandem with other cancer therapies to fight aggressive tumors, scientists reported recently in the Proceedings of the National Academy of Sciences. The researchers demonstrated that adding a molecule called Diprovocim to a vaccine can draw cancer-fighting cells to tumor

Physician researchers with The Ohio State University College of Medicine at the Wexner Medical Center say increased levels of the hormone aldosterone, already associated with hypertension, can play a significant role in the development of diabetes, particularly among certain racial groups. “This research is an important step toward finding new ways to prevent a major

Scientists at the Stanford University School of Medicine have discovered that ketamine works as an antidepressant at least in part by activating the brain’s opioid system. The finding overturns previously held beliefs that the drug’s antidepressant effects stemmed solely from its impact on the glutamate system. These beliefs led to the widespread use of ketamine

Nightmares could be ‘turned off’ after scientists discover the genes that control deep sleep Nightmares could be ‘turned off’ after scientists discover the genes that control deep sleep Two genes discovered that control the rapid eye movement (REM) stage of sleep Dreams occur during REM, which takes place in mammals, including humans Removing the genes

Scientists discover a way to reduce sugar content in cakes by 40% Sweet solution! Scientists discover a way to reduce sugar content in cakes by 40% – without affecting the taste as confectioners plan to alter recipes Experts at Israeli food technology firm DouxMatok were behind the discovery Confectioners have hinted they will alter recipes

Antibiotic use is driving an epidemic of antibiotic resistance, as more susceptible bacteria are killed but more resilient strains live on and multiply with abandon. But if antibiotics aren’t the end-all solution for infectious disease, what is? Salk Institute researchers report that giving mice dietary iron supplements enabled them to survive a normally lethal bacterial
