Scientists have spotted the building blocks of RNA at the center of the Milky Way. They published their findings in Frontiers in Astronomy and Space Sciences. According to the study, the researchers discovered some of those building blocks in a cloud that lies near the center of our galaxy.

The team of researchers discovered the building blocks of RNA in a molecular cloud known as G+0.693–0.027. The discovery, they say, could have implications on the theories about how life on Earth began. It could also shed more light on how life on other planets began, too.

RNA, or ribonucleic acid, is a molecule similar to DNA. It’s present in all living cells and even behaves similarly to the more well-known double-helix. Unlike DNA’s double-strand, though, RNA is only made up of a single strand. Its overall part in the origin of life is unclear. But, there is some evidence the building blocks of RNA could have preceded DNA.

Mike George’s proposal for an autonomous fleet of modular emergency vehicles that can be arranged to form an on-the-go hospital has been awarded third place in Dezeen’s Future Mobility Competition powered by Arrival.

Called National Health Network Modular Hospital System, George’s proposal features a network of modular autonomous vehicles that can be combined into purpose-built clusters to enable hospitals to grow, adapt and respond to emergencies as effectively and flexibly as required.

Each module has a chassis and mobile platform, which can be customised with various interior components to respond to different medical situations. Each interior is designed to foster patient accessibility and comfort, as well as safety.

If flossing is, in short, the bane of your existence, a group of researchers at the University of Pennsylvania might have an ingenious solution for you.

The team has developed the ultimate no-hands dental care in the form of a swarm of shapeshifting microrobots, ready to treat and remove tooth decay-inducing bacteria and plaque from your filthy, unflossed teeth.

In simple terms, the petite and multifunctional robo-dentists do the work of brushing, flossing, and rinsing, all without the tediousness and, in some cases, the challenges of manual oral care.

The search for a way to treat Alzheimer’s disease has puzzled scientists for decades. This may be why some researchers are shifting their focus slightly, investigating whether treating the systems affected by Alzheimer’s (as opposed to the causes) may better help them find a treatment.

This is exactly what researchers of a new study have shown – finding that drugs normally used to treat ADHD may actually show promise in managing symptoms of Alzheimer’s disease.

The researchers conducted a systematic review which looked at how noradrenergic drugs (commonly used for ADHD) work for managing Alzheimer’s disease symptoms. The review found that taking these drugs improved certain brain functions and other symptoms, such as apathy, in patients with Alzheimer’s disease.

Is longevity desirable? Review of biological immortality in storytelling.

And what the prospects are to achieve it in the near future.

The quest for longer lifespan and healthspan.

Since the dawn of human civilization we were inspired by the quest for immortality and eternal youth.

But now, with new advances in medical science, this quest is on the verge of becoming a reality.

Although rare, people become infected by Naegleria fowleri when water containing the amoeba enters the body through the nose. It then travels to the brain, where it destroys brain tissue. This infection cannot spread from one person to another, and it cannot be contracted by swallowing contaminated water.

“These situations are extremely rare in the United States and in Missouri specifically, but it’s important for people to know that the infection is a possibility so they can seek medical care in a timely manner if related symptoms present,” Dr. George Turabelidze, Missouri’s state epidemiologist, said in a statement.

Symptoms can include severe headaches, fever, nausea, vomiting, stiff neck, seizures, altered mental state and hallucinations. Anyone who experiences these symptoms after swimming in a warm body of water should contact their health care provider immediately.
