Millions of Galaxies and Thousands of Asteroids

4 days ago | discovermagazine.com | Monica Cull

The anticipation is over. After over 20 years of hard work, the first images from NSF-DOE Vera C. Rubin Observatory (Rubin) are finally here. With a 10-hour period of observation, the telescope captured 10 million galaxies, thousands of asteroids, and stars across the Milky Way. And because of funding from the U.S. National Science Foundation (NSF) and the U.S. Department of Energy's Office of Science (DOE), these images are only just scratching the surface of Rubin's mission for the next 10 years.
Breathing Lunar Dust Is Bad for Our Bodies, But Not as Bad as City Dust on Earth

What's better for your lungs? A breath full of dust from the moon or from a city on Earth? The answer seems simple enough - especially since the latter is experienced by humans each and every day. But a new study in Life Sciences in Space Research suggests that the healthier option is more surprising than you might think.
FDA Approves Breakthrough HIV Drug, but It Could Be Hard to Access

1 week ago | discovermagazine.com | Monica Cull

In 2022, the Food and Drug Administration (FDA), along with other health organizations, approved the drug lenacapavir as a groundbreaking HIV/AIDS treatment. The FDA, as of June 18, 2025, has now approved the drug as an HIV preventive, or HIV pre-exposure prophylaxis (PrEP). In a 2024 clinical trial, lenacapavir had a 100 percent success rate at preventing HIV transmission with only two injections per year.
A Rare Whale Tooth Reveals a Copper-Age Community's Connection to the Sea

In 2018, a team of archaeologists discovered a fragment of a sperm whale tooth at Valencina, a Copper Age archaeological site near Seville in southwest Spain. Deposited at the site over 4,000 years ago, the find represented one of the first discoveries from a Copper Age site in Spain, but its arrival at the site - some 40 miles from the sea - remained something of a mystery. A new study in solves much of this mystery.
You May Think Animals Are More Human-Like Because of Your Social Life

There are a lot of factors that push people toward conservation, from an interest in preserving species for their contributions to human health to an inclination to protect them for their control of pollutants, pests, or overpopulated prey. But one of the most powerful forces that causes people to support conservation is anthropomorphism - the tendency to see animals as similar to humans.

Extinct Mastodons Still Have an Impact on Modern-Day Ecosystems in South America

1 week ago | discovermagazine.com | Monica Cull

The extinct mastodon continues to have an impact on modern ecosystems in South America. Although this prehistoric ancestor of the elephant species went extinct around 11,000 years ago, the large fruit plants that relied on them for seed dispersal are still around, albeit critically endangered. A new study published in Nature Ecology & Evolution highlights how Notiomastodon platensis, a South American mastodon, was a frugivore and an essential seed spreader.

According to the study authors, the research doesn't just have implications for bacterial neighborhoods; it also has implications for human health and medicine. By harnessing these bacterial weapons, it may be possible to build better targeted antibiotics, designed to overcome antibiotic resistance. Researchers have long known that some bacteria can be ruthless, using weapons like the T6SS to clear out their competition.
Here Are the First Images of the Sun's South Pole, a Completely New View in Our Solar System

2 weeks ago | discovermagazine.com | Sam Walters

The European Space Agency's (ESA's) Solar Orbiter is out of alignment with the rest of the Solar System. And that's a good thing. By orbiting the Sun outside of the Solar System's orbital plane, the spacecraft has captured the first clear images of the Sun's south pole . According to the ESA, these observations (and other observations to come) will provide important insights into the Sun and its activity, with implications for the whole solar system.

Could seeing the luminescent twinkle of fireflies on summer evenings soon be a thing of the past? Recent claims circulating on social media say that we may be the last generation to have grown up with fireflies. But how true is that? A 2024 study in Science of The Total Environment compiled 24,000 North American surveys from Firefly Watch, a citizen science initiative, revealing that firefly populations in North America are declining.
