A simple blood test has the potential to accurately screen for Alzheimer’s disease before symptoms start to show, according to a recent study.

The study, published in JAMA Neurology Monday, found the blood test can identify key plasma biomarkers for Alzheimer’s disease, with up to 97 per cent accuracy.

Here’s how much coronavirus people infected with COVID-19 may exhale

To pin the numbers down, olfactory researcher Gregory Lane and colleagues analyzed over 300 breath samples from 43 people with COVID-19, following them for nearly three weeks.

On average, participants breathed out 80 copies per minute for a full eight days after symptoms began,

The ability to regrow your own teeth could be just around the corner.

A team of scientists, led by a Japanese pharmaceutical startup, are getting set to start human trials on a new drug that has successfully grown new teeth in animal test subjects.

Toregem Biopharma is slated to begin clinical trials in July of next year after it succeeded growing new teeth in mice five years ago, the Japan Times reports

If you’ve ever thought it would be great to walk into a room and know whether the virus that causes COVID-19 is hanging around, scientists have a device for you. Researchers have created a machine a little bigger than a toaster that can detect airborne SARS-CoV-2 coronavirus in minutes.

It takes only five minutes to detect as few as seven to 35 viral particles per liter of air, r.

Summary: Habitual daytime napping could help preserve brain health and slow down the brain shrinkage that comes with aging.

Using Mendelian randomization and examining DNA snippets, researchers linked napping to larger total brain volume, a known indicator of brain health and dementia risk reduction.

The study utilized data from 378,932 UK Biobank participants to identify individuals genetically inclined to nap and their brain health measures.

Long but interesting read

The concept of a brain-like Universe β€” seeded by pre-Socratic philosopher Anaxagoras β€” is gaining currency. The cosmos looks remarkably similar to the complete wiring diagram of the brain β€” and β€œnon-local connections” could enable computation. Stephen Hawking saw a path to a new philosophy of physics based on a view of the Universe as a self-organizing entity.

Β Statins lower risk of deadliest kind of stroke, study finds

Doctors know that drugs called statins lower a person’s risk of a stroke due to a blood clot. But a new study shows that the inexpensive medications can also decrease the risk of a first stroke as a result of an intracerebral hemorrhage, the deadliest kind.

Yet germs are present year-round β€” just think back to your last summer cold. So why do people get more colds, flu and now Covid-19 when it’s chilly outside?

In what researchers are calling a scientific breakthrough, scientists behind a new study may have found the biological reason we get more respiratory illnesses in winter. It turns out the cold air itself damages the immune response occurring in the nose.

Never Kill a Centipede That You Find in Your Home

House centipedes are well-known for eliminating pests such as roaches, moths, flies, and termites that may otherwise hide beneath your furniture.
The 15-legged animal carries venom on two of its legs near its head and scoops up its victim with its other legs, a practice known as β€œlassoing.”
Centipedes do not make nets or webs and do not carry deadly diseases, therefore they are essentially harmless.

Summary: Researchers identified a pathway that begins in the gut and ends with a pro-inflammatory protein in the brain that appears to contribute to the development and progression of Alzheimer’s disease.

They also report a simple way to prevent it.

About 70 million years ago, a wee ostrich-like dinosaur wriggled inside its egg, putting itself into the best position to hatch. But that moment never came; the embryo, dubbed "Baby Yingliang," died and remained in its egg for tens of millions of years, until researchers found its fossilized remains in China.

Researchers have discovered many ancient dinosaur eggs and nests over the past century, but Baby Yingliang is one of a kind.

Why it matters that health agencies finally said the coronavirus is airborne

This year, health experts around the world revised their views about how the coronavirus spreads. Aerosol scientists, virologists and other researchers had determined in 2020 that the virus spreads through the air, but it took until 2021 for prominent public health agencies to acknowledge the fact
