Hidden brain wiring may help keep the mind sharp as gray matter shrinks

Scientists have discovered that the brain’s short-range wiring may help protect cognition even as gray matter shrinks with age. Healthier connections just beneath the brain’s surface were linked to better language skills and appeared to weaken the impact of gray matter loss.

Blind chimp in Louisiana regains sight after cataract surgery

Fifty-four-year-old Pierre was completely blind before undergoing a cataract surgery that restored his sight. With this surgery comes a greater ability to move around his surroundings, participate in fun activities, climb more confidently, and control his dynamics with other chimps (Pan troglodytes). Oh forgot to mention, Pierre is a chimpanzee. He’s a resident at Chimp Haven, a chimpanzee sanctuary in Louisiana (and the largest in the world) where most of the chimps have retired from biomedical research. In humans, cataract surgery is a very common procedure that replaces the eye’s cloudy lens with an artificial one. However, in other animals, it’s not so simple. Pierre required months of preparation, not for the surgery itself, but for his recovery and possible post-operative needs. Before the surgery, Pierre’s team trained him to present his eyes for care, including positioning for the administration of eye drops and close eye monitoring if necessary, according to a statement sent to Popular Science.

Throughout their training sessions, Pierre learned to hold his face against the safety mesh of his enclosure and hold it there with his eyes open for Mary to administer eyedrops. This training was an important step in getting Pierre approved for surgery.” Dr

Asteroid named after ‘Weird Al’ Yankovic

Over the past 50 years, musician “Weird Al” Yankovic has become the first artist to have a comedy album debut at #1 on the Billboard Top 200, been given a star on the Hollywood Walk of Fame, amassed five Grammy awards, and one Emmy. As if that weren’t enough, the “Amish Paradise,” “Eat It,” and “The Saga Begins” singer now has an asteroid named in his honor. The International Astronomical Union (IAU) officially approved the naming of asteroid (14331) Alyankovic earlier this month. The naming citation was published in the WGSBN Bulletin as well as the Minor Planet Center and the Jet Propulsion Laboratory’s Small Bodies Search. Asteroid (14331) Alyankovic is located in the Main Asteroid Belt between Mars and Jupiter. Image: International Astronomical Union. Asteroid names are often used to honor researchers, educators, explorers, and individuals who have made lasting scientific contributions to society. Occasionally, the scientific community will recognize people outside of science whose work has inspired curiosity, creativity, and learning. Many celebrities also have animal species named after them, including Harrison Ford, Queen Victoria, and Kermit the Frog. This particular asteroid award recognizes Weird Al’s influence on scientists, engineers, educators, and students. For many scientists working today, songs such as “It’s All About the Pentiums,” “White and Nerdy,” and “Word Crimes,” and his 2009 short film Al’s Brain: A 3-D Journey Through the Human Brain made intelligence, technology, science, and being unapologetically curious feel fun rather than embarrassing. Weird Al has a long history of encouraging people to celebrate learning through humor. “The asteroid science community believes Weird Al’s influence extends far beyond music,” said Dr. Allison McGraw, a pla

Even morning coffee can mess with your sleep

Coffee drinkers often fall into two groups—those who refuse another cup past a certain time of day, and those who are happy to grab a refill well into the night. The people who practice restraint frequently cite mounting evidence of caffeine’s effects on your sleep cycle, while freewheeling coffee chuggers say they have no problem going to bed after their post-dinner espresso. Unfortunately, a recent study is likely to annoy people on both sides of the argument. According to medical researchers at Poland’s Wroclaw University, coffee’s caffeine content may disrupt a person’s nightly sleep quality no matter when they brew a pot. The findings are detailed in a recent study published in the journal Nutrients. For their analysis, researchers relied on electroencephalography (EEG) scans collected during a clinical sleep experiment. Standard sleep assessments typically focus on sleep cycle duration, but EEG is designed to record much more detailed information about quality of rest. “EEG allows us to see not only whether a person is sleeping, but also how the brain is sleeping,” study co-author and Wroclaw University family medicine specialist Donata Kurpas recently told Science News. “Quantitative EEG analysis reveals more subtle changes, such as reduced slow-wave activity, which is an important marker of sleep depth and its restorative character.” Kurpas and her colleagues learned during their examinations that even if someone falls asleep at a normal time and remains asleep for the full recommended eight hours, caffeine can still dramatically cut down on their brain’s slow-wave activity. This means that even if a person assumes they got a full night’s sleep, the actual quality may be compromised. “Caffeine may shorten sleep or make it more difficult to fall asleep; however,
