By some estimates, as many as 4 in 5 people diagnosed with Parkinson's disease go on to develop dementia in the next 15 years.
As intimidating as the figure might be, those predictions are often based on studies with numerous limitations and small sample sizes, calling into question just how closely linked these two neurological conditions might be.



					
			

New research carried out by researchers from the University of Pennsylvania, suggests that the chances of having dementia 15 years following a  Parkinson's diagnosis is more like 50 percent, only reaching 74 percent after 20 years.
That's significantly lower than previous estimates: earlier studies...

Hopeful Parkinson's Study Shows Risk of Dementia Is Lower Than Feared


A new study has revealed for the first time the molecular structure of brains affected by  Alzheimer's disease.
Researchers have produced 3D models of proteins in the brain, including two proteins in particular that are associated with Alzheimer's: beta-amyloid and tau.



					
			

As scientists continue to work towards treatments for the neurodegenerative disease, it's important to understand as much as we possibly can about it.
Clumps of these proteins in the brain are either a cause of Alzheimer's or a consequence of it – we're not quite sure which yet – and thanks to a team from the University of Leeds in the...

3D Molecular Structure of Alzheimer's Brains Revealed For The First Time


The face of an ancient Egyptian mummy set in a gaping rictus may be the result of a death so painful, her face may have become locked in a scream.
Her name is unknown; but so striking is her grim facial expression that she is referred to as the Screaming Woman mummy. In spite of the feelings this face engenders, researchers had previously attributed it to the relatively benign cause of a shoddily performed mummification. New research, however, suggests that this wasn't the case.

(MA) Meet Yoda, a tiny 9-pound senior Shih Tzu who is ready to steal your heart. This little pup is an older boy who has lived his life loved by a caring owner. Sadly, his owner recently passed away, and their family was not able to take care of Yoda. Luckily, Great Dog Rescue New England was able to take him in and place him safely with a foster. He still has a lot of life left in him, and he hopes to spend the majority of it snoozing in YOUR bed.

This Tiny Shih Tzu Who Lost His Owner Is Now Looking For New Family


A little-known form of dementia, easily mistaken for Alzheimer's disease, now has a brand new name and specific diagnostic criteria.
Researchers are calling it limbic-predominant amnestic neurodegenerative syndrome (LANS), and they hope that their work makes it easier for medical professionals to care for and counsel patients with various forms of memory loss.



					
			

LANS presents with a different set of brain changes to  Alzheimer's, and it tends to progress slower and with milder symptoms, mostly impacting those over the age of 80.
Similar to Alzheimer's, a definitive diagnosis is only available upon autopsy.
To help those living with memory loss, neurologist Nick Corriveau-Lecavalier...

Scientists Name New Type of Memory Loss Often Mistaken For Alzheimer's


A 58-year-old man in the United States is the first person in the world to have had his failing heart replaced with a temporary, titanium blood-pumper.
The metal organ looks like it was made for the Tin Man, but it was actually designed by the medical device company BiVACOR to replace the full function of a flesh-and-blood human heart for as long as possible.



					
			

BiVACOR's Total Artificial Heart (TAH) is not designed to beat like a real one. But even without flexible chambers or pumping diaphragms, BiVACOR claims it is powerful enough to sustain a man during exercise, and small enough to...

The ancient monument of Göbekli Tepe in Türkiye is truly one of the most magnificent ancient marvels on our planet.
The temple complex that thrived as a cultural epicenter more than 10,000 years ago is the oldest monument of its kind, handing down mysteries from a people long, long past.



					
			

And now, a carving on a wall in the complex could be the earliest evidence of a calendar, used to track the passage of time and the turning of the seasons.
We don't know exactly how the Neolithic people of Türkiye used Göbekli Tepe, but recent findings suggest that it was occupied at...

As a summer surge of the Coronavirus is underway across the country, a new study has revealed the states with the lowest COVID-19 vaccination rates among adults, and Kentucky has finished among the bottom 10.

Kentucky ranks ninth in recent study of states with lowest COVID-19 vaccination rates


The  virus responsible for  COVID-19 is now widespread in wildlife. A new study in the US identified exposure rates of up to 60 percent in some species.
"I think the big take-home message is the virus is pretty ubiquitous," says Virginia Tech conservation biologist Amanda Goldberg. "We found positives in a large suite of common backyard animals."



					
			

Testing almost 800 nasal and oral swabs from animals in rehabilitation centers or that were trapped and released in the wild, the researchers identified six different species with  antibodies indicating they'd been infected with  SARS-CoV-2 at some point.
Most of the infected...

Virus Behind COVID-19 Now Rampant in Wild Animals, Study Finds


Losing a mouthful of teeth, as can happen in older age, has been linked to a greater risk of dying from heart disease, stroke, and other fatal heart events in a new analysis.
Studies before this have pointed to a link between missing one or more teeth and a higher risk of heart disease and cardiovascular diseases, more broadly.



					
			

Poor oral health is also a known risk factor for cardiovascular diseases (CVDs), a group of conditions affecting the heart and blood vessels, which tallied together represent the leading cause of death globally.
It might sound like a strange connection, but it's plausible that...

The mantis shrimp is one tough customer. Beautiful and deadly are two words you don’t typically use to describe shrimp, but the mantis shrimp is definitely in a class of its own; earning a reputation as the ‘savage boxer of the sea’ and one of the most fearsome creatures in the ocean. And, they're right at home here in South Carolina.

Eventually, we're going to want to expand the World Wide Web across the galaxy, and NASA recently demonstrated a key piece of tech that could help, beaming messages via laser across a distance of almost 16 million kilometers (10 million miles).



					
			

That's about 40 times farther than  the Moon is from Earth, and the accomplishment, achieved in November 2023, represented the first time that optical communications have been sent across such a distance.
Traditionally, we use radio waves to talk to distant spacecraft – but higher frequencies of light, such as near infrared, offer an increase in bandwidth and therefore a...

It's been nearly a century since scientists discovered single-celled organisms capable of spewing methane into the environment.
While these microscopic cousins to bacteria occupy a variety of extreme habitats – under kilometers of ice, among the hot sands of deserts, near hydrothermal vents in the deep sea, and within landfills and wastewater – they have all belonged to the same superphylum within the Archaea kingdom, called Euryarchaeota.



					
			

It turns out, they are not alone.
Around ten years ago, scientists working around oil fields and hot springs uncovered DNA from undescribed microorganisms, which suggested they might produce methane gas. Unlike every other 'methanogen' known...

Homo floresiensis holds the record for the smallest human species to have ever graced our planet, but some of them might have been even smaller than we first imagined.
A 700,000-year-old fragment of an adult humerus uncovered in 2013 has recently been classified as belonging to an early representative of a species once colorfully described as 'hobbits'.



					
			

Smaller than any in the fossil record – from this ancient cousin or any other hominin for that matter – the piece of upper arm bone expands the picture we have of an unusual relative that walked on Earth alongside us until as recently as...

Neuroscientists think they have identified the large-scale neural network that keeps the brain's creative juices flowing.
Unlike specific movements or sensory responses, creative thought isn't confined to any one part of the brain's wrinkled outer cortex. But a team of researchers, led by Baylor College of Medicine, think they have found the brain circuits fundamental to some types of creativity.



					
			

When nine adult participants had specific parts of their default mode network (DMN) temporarily suppressed via deep brain stimulation, they were no longer able to think outside of the box to the same extent.

A tree common in gardens for its pretty flowers and foliage has been harboring a secret this entire time.
The wood of the two species of tulip tree (Liriodendron) is neither hardwood nor softwood, but a type of wood in between, something we didn't even know existed. And this wood, researchers say, seems to be particularly efficient at carbon sequestration and storage.



					
			

This ability, say biochemists Jan Łyczakowski of Jagiellonian University in Poland and Raymond Wightman of Cambridge University in the UK, could be related to the size of the tree's macrofibrils, long threadlike bundles of cell wall components and cellulose, which...

Humans have an incredible ability to guess a person's name simply based on the appearance of their face.
A new study has found it could be a case of self-fulfilling prophecy.
When a photograph of an adult was shown to participants with four possible name choices, they chose the correct name at a rate well above chance. When child faces were shown, however, the study's participants weren't nearly as good at matching faces to names.



					
			

The findings suggest that we tend to alter our appearance as we mature to better suit our own names, whether it be through hairstyles, makeup, glasses, piercings, or...
