Picking your nose might seem harmless albeit gross, but new research is showing it may have some devastating consequences, according to a press release published by Griffith University Friday.

A direct path to the brain

The new research demonstrates 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 tell-tale sign of Alzheimer’s disease.

New research from SAHMRI has found a link between the omega-3 fatty acid known as docosahexaenoic acid (DHA) and increased IQ among children born prematurely.

Preterm children are more likely to have lower IQ scores and cognitive impairments compared with term-born children.

Dr. Jacqueline Gould, who led the study now published in the New England Journal of Medicine, says infants born at the earliest gestations are deprived of the natural supply of DHA that normally builds up in the brain during the last trimester of pregnancy.

Biomedical and electrical engineers at UNSW Sydney have developed a new way to measure neural activity using light—rather than electricity—which could lead to a complete reimagining of medical technologies like nerve-operated prosthetics and brain-machine interfaces.

Professor François Ladouceur, with UNSW’s School of Electrical Engineering and Telecommunications, says the multi-disciplinary team has just demonstrated in the lab what it proved theoretically shortly before the pandemic: that sensors built using liquid crystal and integrated optics technologies—dubbed “optrodes”—can register nerve impulses in a living animal body.

Not only do these optrodes perform just as well as conventional electrodes—that use electricity to detect a nerve impulse—but they also address “very thorny issues that competing technologies cannot address,” says Prof. Ladouceur.

10 years ago we saw a breakthrough in modern biology.

An American scientist discovered that manipulation of the Cas9 protein resulted in a gene technology worthy of a sci-fi film: CRISPR.

Think of it as a pair of molecular scissors capable of cutting and editing the DNA of humans, animals, plants, bacteria and viruses.

Researchers from the Chinese Academy of Sciences‘Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) have recently found two fossil repositories in the early Silurian strata of southwest Guizhou and Chongqing that are rewriting the “from fish to human” evolutionary story.

Four different papers describing their findings were recently published in the journal Nature.

The results of a phase I clinical trial show that a new drug candidate could safely target pancreatic, lung, colon, and other cancers in humans.

Rheumatoid arthritis affects 1 in 100 people worldwide. It causes inflamed, painful and swollen joints, often in the hands and wrists, and can lead to loss of joint function as well as chronic pain and joint deformities and damage. What causes this condition has been unknown.

In our recently published study, my colleagues and I found an important clue to a potential culprit behind this disease: the bacteria in your gut.

GENEVA (AP) — The number of people infected with tuberculosis, including the kind resistant to drugs, rose globally for the first time in years, according to a report Thursday by the World Health Organization.

The U.N. health agency said more than 10 million people worldwide were sickened by tuberculosis in 2021, a 4.5% rise from the year before. About 1.6 million people died, it said. WHO said about 450,000 cases involved people infected with drug-resistant TB, 3% more than in 2020.

Dr. Mel Spigelman, president of the non-profit TB Alliance, said more than a decade of progress was lost when COVID-19 emerged in 2020.

Two lots of quinapril and hydrochlorothiazide tablets have been recalled due to the presence of nitrosamines, according to a notice posted on the Food and Drug Administration’s website.

Nitrosamines are common in water and foods, including cured and grilled meats, dairy products and vegetables and may increase the risk of cancer if people are exposed to them above acceptable levels over long periods of time.

The pink, round tablets contain 20 milligrams of quinapril and 12.5 milligrams of hydrochlorothiazide and are supplied in 90-count bottles with an expiration date of January 2023. The drug is used to treat hypertension and lower blood pressure.
