This emerging treatment could help people avoid knee replacement surgery

A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood vessels associated with inflammation, GAE can significantly reduce pain, with some patients reporting little or no pain afterward. Studies suggest the benefits may last two to four years in people who respond well.

An Epic View of the Seasons

The tilt in Earth’s axis of rotation makes the apparent position of continents shift with the seasons in imagery from a NASA camera in deep space.

Scientists discover first new penguin species in more than 100 years

Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threat, as warming oceans could leave several island populations with little suitable habitat by 2050.

Brain scans reveal a possible cause of long COVID fatigue and brain fog

Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.

Stopping Ozempic may raise heart attack and stroke risk

A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the medications, patients had a 22% higher risk of heart attack, stroke, and death compared with those who stayed on them.

Stem cells reverse stroke damage and restore movement in mice

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.

Embracing the Equinox

Depending on your locale, equinoxes can be seen as harbingers of longer nights and gloomy weather, or promising beacons of nicer temperatures and more sunlight. Observing and predicting equinoxes is one of the earliest skills in humanity’s astronomical toolkit. Many ancient observatories around the world observed equinoxes along with the more pronounced solstices. These days, […]

Perseverance’s View of ‘Turquoise Bay’

Description NASA’s Perseverance Mars rover used its Mastcam-Z camera to capture this 360-degree panorama of “Turquoise Bay,” a geologic area of interest in the “Margin Unit.” The 818 images used to create the natural-color panorama were captured between Oct. 5 and Oct. 16, 2023, the 933rd to 944th Martian days, or sols, of the mission. […]

NASA Discovery Reveals Complex Water Systems on Early Mars

When NASA’s Perseverance rover reached the inner edge of Mars’ Jezero Crater in September 2023, mission scientists were surprised by what they found. Called the “Margin Unit,” the geologic area stretches along the shoreline of an ancient Martian lake, so they expected sedimentary rocks, which would have formed as layers of sand piled on top […]
