Play Video: Diversity in #tongues provides a way to study #evolution

An early interest in #reptile feeding behavior led evolutionary biologist Kurt Schwenk to study the tongues of lizards, amphibians and snakes. Like Charles Darwin's finches, the various forms and functions of #lizard tongues help piece together the story of how diversity of reptiles and amphibians evolved.

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.

Play Video: Marine snow mucus might mean slower carbon capture #science #oceanography #carboncycle

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.

An Ethiopian wolf (Canis simensis) laps up nectar from three Ethiopian red hot poker flowers (Kniphofia foliosa) in the country’s Bale Mountains National Park. Anecdotal reports from researchers monitoring the wolves suggest that they hunt rodents during the day and slurp nectar in the afternoon, says wildlife biologist Sandra Lai, almost like the carnivores are getting dessert.

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
