Honey appears to be a preferable treatment for cough or cold symptoms rather than antibiotics and over-the-counter medicines, according to a new systematic review that’s looked at the results from 14 previous studies — but the conclusions may not be quite so clear-cut as they appear at first.

“Honey is a frequently used lay remedy that is well known to patients,” write the researchers from the University of Oxford in the UK. “It is also cheap, easy to access and has limited harms.”

One particular area of interest is the comparison of honey to antibiotics. With antibiotics often causing side effects and antibiotic resistance on the rise, there are multiple advantages to using honey as an alternative remedy, the authors of the review point out.

Summary: Researchers identified a group of closely related genes that capture molecular links between Alzheimer’s and LATE, a common brain disorder that mimics Alzheimer’s symptoms.

Alzheimer’s disease is one of the most common causes of dementia, and while most people might know someone who is affected by it, the genetic factors behind the disease are less known. A new study by investigators from Brigham and Women’s Hospital uncovered a group of closely related genes that may capture molecular links between Alzheimer’s disease and Limbic-predominant Age-related TDP-43 Encephalopathy, or LATE, a recently recognized common brain disorder that can mimic Alzheimer’s symptoms. LATE is often combined with Alzheimer’s disease to cause a more rapid cognitive decline. The study’s results are published in Neuron.

Machine logic can be too precise to seem fully human. Chatbots that learn logic from Aristotle instead might behave more like people.

Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Earth.

Kepler’s supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. In 1604 early astronomers, including Johannes Kepler who became the object’s namesake, saw the supernova explosion that destroyed the star.

NASA’s Mars rovers have been one of the great scientific and space successes of the past two decades.

Four generations of rovers have traversed the red planet gathering scientific data, sending back evocative photographs, and surviving incredibly harsh conditions—all using on-board computers less powerful than an iPhone 1. The latest rover, Perseverance, was launched on July 30, 2020, and engineers are already dreaming of a future generation of rovers.

While a major achievement, these missions have only scratched the surface (literally and figuratively) of the planet and its geology, geography, and atmosphere.

The Raptor engine, designed to power the ship that will send humans to Mars and beyond, has been racking up impressive test results.

Beetle-size machine can climb, crawl, and carry heavy objects—all without batteries.

Aug. 18 (UPI) — New research suggests harmful cosmic rays from a nearby supernova might have caused the extinction events that form the boundary between the Devonian-Carboniferous periods.

Around 360 million years ago, a lengthy period of biodiversity declines culminated in a series of extinction events that saw 19 percent of all families and 50 percent of all genera disappear.

Scientists have previously unearthed a diversity of Late Devonian plant spores that show evidence of being burnt by ultraviolet light, signs of a prolonged ozone-depletion event.
