Wednesday Science News Roundup #20

Below are 10 science news that I found interesting and are related to topics I care about.

Diabetes drug ‘significantly reverses memory loss’ in mice with Alzheimer’s – A drug developed for diabetes could be used to treat Alzheimer’s after scientists found it ‘significantly reversed memory loss’ in mice through a triple method of action. This is the first time that a triple receptor drug has been used which acts in multiple ways to protect the brain from degeneration. It combines three growth factors. Problems with growth factor signalling have been shown to be impaired in the brains of Alzheimer’s patients. Science Daily

State-of-the-art MRI technology bypasses need for biopsy – The most common type of tumor found in the kidney is generally quite small (less than 1.5 in). These tumors are usually found by accident when CAT scans are performed for other reasons and the serendipitous finding poses a problem for doctors. Science Daily

New brain mapping technique highlights relationship between connectivity and IQ – A new and relatively simple technique for mapping the wiring of the brain has shown a correlation between how well connected an individual’s brain regions are and their intelligence, say researchers. Science Daily

Food Comas Are Real And They’re Slowing Down Your Brain, New Study Finds – Ever felt your brain a little sluggish a little while after eating sugar or a giant meal? You are probably feeling the effects of a sugar crash, which, new research shows, really can slow down your cognitive function. Science Alert

Some People Have an Uncanny Sixth Sense For Detecting Sickness – Humans may possess an inherent ability to detect sick people from subtle visual cues. This skill could act as a behavioural defence against disease by limiting the risk of contamination, according to new research. Science Alert

If We Don’t Act Now, Climate Change Could Devastate The Chocolate Industry In Just 30 Years – It’s that time of the year when even just looking at another piece of chocolate runs the risk of making you feel slightly queasy. But our insatiable appetite for the sweet treat coupled with predicted temperature rises due to climate change could mean that we might run out of chocolate within just three decades if nothing is done to prevent it.

Hybrid Bird Species Discovered In The Amazon For The First Time– A species of bird first described in 1957, but then not seen again until its rediscovery 45 years later, is even more mysterious than previously thought. It turns out that the golden-crowned manakin – a small, vivid green bird with a yellow noggin – is actually the result of a hybridization event between two other species of manakin birds. IFLScience

The World Didn’t Have Many Natural Disasters In 2017 (Except For The US) – It’s fair to say that the US will remember 2017 for two things: political shitstorms and literal storms. Over the past year, North America has had more than its fair share of extreme weather events, from an onslaught of hurricanes and blazing wildfires to droughts and floods. IFLScience

A sinking, melting ancient tectonic plate may fuel Yellowstone’s supervolcano – The driving force behind Yellowstone’s long and explosive volcanic history may not be as deep as once thought. A new study suggests that instead of a plume of hot mantle that extends down to Earth’s core, the real culprit is a subducting tectonic plate that began sinking beneath North America hundreds of millions of years ago.

Spider’s web inspires removable implant that may control type 1 diabetes – For the more than 1 million Americans who live with type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a team has developed a device that could revolutionize management of the disease. Science Daily
