Four distinct variants of Alzheimer’s identified in brain imaging study

Posted on by

Researchers have detected four types of Alzheimer's by tracking different patterns of tau protein accumulation in the brains of patients

A new international study has found four distinct patterns of toxic protein spread in the brains of patients with Alzheimer’s disease. The findings indicate these patterns correspond with particular symptoms, and the researchers hypothesize these four variants could respond to different treatments.

Study suggests tiny birds’ blood gets warmer in the winter

Posted on by

In order to stay warm on frigid winter days, small birds may do more than just fluff up their feathers. According to new research, they’re actually able to make their blood run hotter, creating a sort of central heating system.Continue ReadingCategory:… Continue reading Study suggests tiny birds’ blood gets warmer in the winter→

Butterflies cup their wings to produce tiny jets and evade predators

Posted on by

By analyzing the way butterflies rapidly take flight in wind tunnel experiments, scientists have uncovered new detail around how the insects evade predators. The mechanics of their wings were found to help generate small pockets of air that can quickly… Continue reading Butterflies cup their wings to produce tiny jets and evade predators→

Blood tests are emerging as an exciting tool for the detection of Alzheimer's disease in its early stages

Blood tests are starting to show real potential as a way of detecting Alzheimer’s disease in its early stages, with a number of studies producing highly promising results in the past couple of years. Joining them is a new test that can analyze markers in the blood of those with mild memory loss to determine the risk of them going on to develop Alzheimer’s within two to four years.

A new blood test could one day aid in the early diagnosis of Alzheimer's

Alzheimer’s is a disease that can take hold in the brain long before symptoms, like memory and cognitive decline, become evident. This makes it a very tricky one to diagnose early in the piece, but a new breed of blood tests are emerging that could change the game in this regard. The latest centers on a new biomarker in the blood, which was shown to distinguish healthy patients from early asymptomatic Alzheimer’s patients with a high degree of accuracy.

"Eco-friendly" neurotoxin may find use in malaria-mosquito-specific insecticide

Posted on by

According to the World Health Organization, an estimated 429,000 people die from malaria annually. And while it’s tempting to spray heavily for the mosquitoes that spread the disease, conventional insecticides are also toxic to humans and oth… Continue reading "Eco-friendly" neurotoxin may find use in malaria-mosquito-specific insecticide→
