Play Video: Can a twice-a-year shot help end the HIV/AIDS epidemic

HIV infects more than a million people every year worldwide. While decades of research have led to effective treatments and pre-exposure prophylactic (PrEP) drugs that have dramatically reduced the impact of HIV/AIDS epidemic, completely wiping the virus out has remained out of reach. Lenacapavir, a new twice-yearly PrEP injection, may be the solution. Two clinical trials this year showed the drug can offer near complete protection from HIV infection, and the long-lasting effects mean daily pills could be a thing of the past, as long as it is accessible to populations who need it most. Science journalist Jon Cohen, physician-scientist Linda-Gail Bekker, and biochemist Wesley Sundquist describe the history of HIV/AIDS prevention and the unique mechanism that led lenacapavir to be named the 2024 Breakthrough of the Year.

After an oil spill, bacteria like Alcanivorax borkumensis can help the cleanup process, consuming oil and breaking it down. A group of biophysicists have observed how a biofilm forms around the oil and push and pull the oil's surface into branching tubes.

Marine snow is the dead, discarded, and sloughed off organic matter that floats down to the sea floor like snowflakes. Originating from living organisms at the surface, then dropping down to the depths, it's an important part of how the ocean captures carbon from the atmosphere. However, by analyzing the sinking patterns of individual marine snowflakes, researchers found that their mucus trails slow their sinking speed, meaning this process captures carbon much slower than previously thought.

This flatworm species has the most extreme soldiers yet among parasites. When the nest of Haplorchis puilio is threatened, the soldiers crawl up to the foreign trematodes, attach their mouths, and expand their throats. The resulting vacuum blows a hole in the larger parasites, allowing the soldiers to suck out their guts. Video by: Sierra Boucher/Science Footage: Daniel Metz Music: Chris Burns/Science

Researchers put vampire bats through their paces to discover what fuels their metabolism. After a fine meal of cow blood, bats were put into a closed mini-gym with a moving floor. As the bats walked and then — as the treadmill sped up — ran, researchers checked bat breath for signs that amino acids from the cow blood were getting metabolized in the workout. Unlike most mammals burning carbs and fats during exercise, bats metabolize more amino acids.

A sit-and-wait flirter, a male riflebird (left in the first clip) puts on a high-energy — and noisy — show for a female visiting his perch. The most flexible wrist joints yet measured in a bird let him curve his dark wings like a flaring cape. Opening and closing his beak, as seen in the first slow motion clip, adds flashes of gold from the mouth and throat lining. Between flashes, he closes his beak to scrape it over the spread feathers for the show’s thwackity-thwack soundtrack, as seen in the second slow motion clip. Scientists previously thought the birds somehow clapped their wings together to make the sounds. Video: Thomas MacGillavry and Joris De Raedt

This animation shows how the ambipolar electric field works. The most abundant gas in the lower atmosphere, the part we live in, is nitrogen (N2, shown around seven seconds). Pan up to the ionosphere (14 seconds), though, and you’ll find more atomic oxygen. Photons from the sun can collide with oxygen and knock one of their electrons loose, leaving a positively charged oxygen ion behind. The pull between those ions and their lost electrons is the ambipolar electric field, which ties them together.
