Imaging study offers clue to how obesity can increase Alzheimer’s risk

A direct association between increased body weight and reduced blood flow in the brain was detected in a new study

New data from one of the largest brain imaging studies of its type has found a consistent association between increased body weight and decreased cerebral blood flow. The research offers greater insights into the links between Alzheimer’s and obesity, suggesting maintaining a healthy weight can directly reduce one’s risk of developing dementia.

Satellites and penguin poop reveal new emperor penguin colonies

A team of scientists from the British Antarctic Survey (BAS) led by geographer Peter Fretwell has used satellite imagery of penguin poop captured by ESA’s Copernicus Sentinel-2 mission to calculate that there are 20 percent more emperor penguin colonie… Continue reading Satellites and penguin poop reveal new emperor penguin colonies

New drug target in humans activates brown fat to burn excess energy

Scientists have previously shown how to activate energy-burning brown fat in mice, which helps shed weight and improves health. Results have been hard to replicate in humans, but a new study has found that we might be targeting the wrong receptor in ou… Continue reading New drug target in humans activates brown fat to burn excess energy

Anti-aging drug targets Alzheimer’s by altering metabolism in the brain

Scientists studying the effects of an experimental drug in mice have uncovered new mechanisms that appear to drive the development of Alzheimer's

Scientists investigating Alzheimer’s treatments at the Salk Institute have uncovered some key mechanisms that enable an experimental drug to reverse memory loss in mouse models of the disease. The discovery not only bodes well for the possibility of clinical trials, but provides researchers with a new target to consider in the wider development of compounds to counter the degenerative effects of the condition.

DJI sets up education branch, launches first product

China’s DJI Innovations is probably best known for its consumer and enterprise drones, and maybe even its smartphone stabilizers, but last year the company launched an educational robot platform named after its annual RoboMaster Robotics Competition. N… Continue reading DJI sets up education branch, launches first product

Moth eyes inspire anti-icing surface for aircraft, and maybe eyewear

The unique arrangement of nanoscale bumps coating a moth’s eye have inspired all kinds of interesting technological advances, owing to the incredible antireflective properties that allow the eye to absorb almost all the light that hits it. These range … Continue reading Moth eyes inspire anti-icing surface for aircraft, and maybe eyewear

Large clinical trial affirms vitamin D does not prevent depression

The results of the largest clinical trial ever conducted into the relationship between vitamin D and depression suggest the important vitamin does not improve mood or prevent depression. The randomized, placebo-controlled trial did not investigate subj… Continue reading Large clinical trial affirms vitamin D does not prevent depression

Upping the contrast enables daytime laser tracking of space debris

A team of ESA scientists has developed a way to use lasers to accurately track space debris even in broad daylight. Using a combination of special telescopes, detectors, and light filters tuned to specific wavelengths, it’s now possible to increase the… Continue reading Upping the contrast enables daytime laser tracking of space debris
