Digging your nose is a curious habit. Some people pick their nose out of boredom or nervousness. However, according to a new study, this habit could put you at a risk of developing Alzheimer's and dementia. According to a team of researchers at Griffith University, Australia, they demonstrated that a bacteria can travel through the olfactory nerve in the nose and into the brain in mice, where it creates markers that are a revealing sign of Alzheimer's disease.

Scientists are searching far and wide for new tools in the battle against rising obesity rates, and lately a promising candidate has emerged from piles of purified sand. A new study has bolstered the potential of silica particles made from this material by showing how they block enzyme activity to hamper the body’s uptake of fats and sugars, while also hinting at the ideal design for the optimal anti-obesity effects.

An 86-year-old bodybuilder broke his own record as the oldest person to compete in the Japan championships on Oct. 9. Toshisuke Kanazawa, who lives in the city of Hiroshima, took part in the 68th edition of the men's Japan bodybuilding championships in Osaka, going up against young bodybuilders with exquisite poses.

“Forever chemicals,” or perfluoroalkyl and polyfluoroalkyl substances (PFAS), have made quite a few appearances in the news cycle lately. These thousands of manufacturing chemicals leach into the food and water supply, making it nearly impossible to avoid absorption into the human body. Once in the body, they don’t go away—hence the name “forever chemicals”—and can cause a host of health concerns, from thyroid disease and cancer to liver damage and fertility issues.

A male contraceptive jab that last 10 years and prevents men passing HIV and other sexually transmitted diseases could be available within a year. The injection will be less painful and also reversible making it more simpler than a vasectomy. Researchers at the Indian Institute of Technology have completed final trials of the jab and experts say the jab known as Risug- an acronym for reversible inhibition of sperm under guidance - could be available within 12 months.

The path to recovery starts with hope.

For all the advances in medical technology humans have developed, there is one thing it hasn't been able to do: stop us from getting old. We've managed to extend the human lifetime dramatically in the last couple of centuries, greatly diminishing infant and child mortality and pushing back on disease with antibiotics and vaccines.

We’ve all been told our whole lives we need ‘good’ posture: sit up straight, stand straight with shoulders back, and lift by bending the knees. It turns out there’s really no evidence for that advice.

At a time when every dollar counts, many of us are changing the way we eat to save money. Take mother of three and Hong Kong resident Asher Chan, for instance. A lifelong vegetarian, she transitioned to veganism in the past year for a couple of reasons – one of which was the rising cost of milk and eggs. Now her family uses plant-based alternatives to these foods, which she says are more affordable.

Eating Jarlsberg cheese may help to prevent bone thinning and stave off osteoporosis, research suggests. Jarlsberg is a mild cheese made from cow’s milk, with regular holes that mean it is classified as a Swiss-type cheese, although it originates from Norway. It is rich in vitamin K2, which has previously been found to improve bone health.

The likelihood of developing a CV is predicted to rise dramatically among minorities while falling among White people.

Eating a balanced and healthy diet is essential for maintaining a healthy lifestyle. It's not always easy to know which foods to eat in order to achieve this, however.

To the average viewer, this year’s Wimbledon Finals matchup was nothing shocking, with two distinctly different players vying for the Cup, but the two finalists share one unique characteristic: They both follow vegan diets. Defying claims that plant-based diets lack for protein or hinder athletic performance, vegan athletes worldwide have proved otherwise...

Adding salt to meals at the table is linked to an earlier death, according to a study of 500,000 middle-aged Britons. Researchers found that always adding salt to food knocks more than two years off life expectancy for men and one-and-a-half years for women. This does not include seasoning during the cooking process.

Because the heart, unlike other organs, cannot heal itself after injury, heart disease—the top cause of mortality in the U.S.—is particularly lethal. For this reason, tissue engineering will be crucial for the development of cardiac medicine, ultimately leading to the mass production of a whole human heart for transplant.

Most humans can learn how to echolocate, using their tongue to make clicking sounds and interpreting the echoes that come back, reflected from the surrounding environment. Despite how useful this skill can be, very few blind people are currently taught how to do it.

Injectable, biodegradable technology developed by UK team works as a scaffold to help new tissue grow!

The clock used a simple statistical model, which looked at a certain type of epigenetic modification at just two target sites on DNA.

Many people who struggle with addiction feel a lot of guilt and shame over their use. A new study published in PLOS One suggests that independent of depression, this shame and guilt can be significant barriers to reducing drug use, which has considerations for recovery.

People who drink coffee – whether with or without sugar – appear to have a lower risk of an early death, although experts caution the finding may not be down to the brew itself.
