Science Quickly

Sick coral reefs are visually striking—bleached and lifeless, far from the vibrancy we’ve come to expect. But what does an unhealthy coral system sound like? In this rerun, conservation bioacoustics researcher Isla Keesje Davidson tells Science Quickly all about the changing soundscape of the seas.

Drone shows are replacing fireworks for summer celebrations. They’re safer and more environmentally friendly but complicated to program and run. A recent preprint paper proposes an algorithmic solution that can take some technical challenges out of drone operators’ hands and give engineers more creative control. Host Rachel Feltman speaks with researchers Mac Schwager, an associate professor at the aeronautics and astronautics department at Stanford University, and Eduardo Montijano, an associate professor at the department of computer science and systems engineering at the University of Zaragoza in Spain, about their work and what it would take to move the algorithm from theory to the skies.

Protests around the construction of the now complete Dakota Access Pipeline brought national attention to Energy Transfer, the company that built and owns the pipeline and funded private security against the protestors. Energy Transfer sued the nonprofit Greenpeace for hundreds of millions of dollars. The company claimed that the Standing Rock movement was not Indigenous-led environmental activism but a conspiratorial effort by Greenpeace. Reporter Alleen Brown is spending this season of her podcast, Drilled, looking into the lawsuit and the message that legal actions like this send to activists.

Creating a bird flu vaccine requires several layers of bioprotective clothing and typically a whole lot of eggs. H5N1 avian influenza infections have gone from flocks of chickens to herds of cattle and humans. Scientists at the Texas Biomedical Research Institute are taking their best guess at the strains of the virus that could spread and are creating critical vaccine candidates.

Multimedia journalist and Scientific American multimedia intern Naeem Amarsy suited up and went to San Antonio, Tex., to visit a “biosafety level three” (BSL-3) lab at the institute. 

This is the third and final episode of our series about bird flu.

Dairy cattle have become an intermediary between avian influenza found in wild birds and the handful of recorded H5N1 bird flu cases in humans. Senior news reporter Meghan Bartels took a trip upstate to Cornell University’s Teaching Dairy Barn. Early last year Texas dairy farmers noticed lethargic cows producing off-color milk. One of them sent Cornell researchers a sample, which genetic sequencing determined to contain a strain of H5N1. That strain traces its roots to the H5N1 virus that emerged in China in the late 1990s—which spread around the world thanks to migrating wild birds, such as those found on the beach that associate health and medicine editor Lauren Young visited in episode one of our three-part series about bird flu. And outbreak of H5N1 has been running through poultry farms since the early 2020s. Poultry farmers have been forced to cull flocks, reinforce biosecurity protocols and change the prices of eggs as a result. Dairy farms were less prepared for the spillover and its unexpected transition into raw-milk-drinking barn cats. While pasteurization makes milk safe for human consumption, there’s no easy way to prevent the spread between herds of cattle. In the next episode, multimedia intern and producer Naeem Amarsy looks at how the virus made yet another hop—this time into humans.

Bird flu outbreaks in poultry and cattle have caused concern for public health officials. There have been few reported cases of human transmission, but the growing risks of H5N1 avian influenza have virologists on alert.

Researchers at the St. Jude Center of Excellence for Influenza Research and Response take an annual visit to Delaware Bay to collect samples of bird poop for analysis. These samples give the researchers a look at emerging avian illnesses. While spillover of H5N1 into domestic birds has been known for a while, the first case of spillover into humans was only identified during a 1997 outbreak in Hong Kong. Since then H5N1 has gone global and moved from transmitting from bird to bird to spreading from bird to mammal and from mammal to mammal.

Associate health and medicine editor Lauren Young takes a sample collection walk on the beach and speaks with virus detectives about how H5N1 evolved in episode one of our three-part series about bird flu.

Join us on Wednesday to learn how bird flu jumped from poultry to cattle.

Testosterone replacement therapy (TRT) is exploding in popularity among men. TRT has been touted online as a cure-all for everything from low energy to poor mood and even as a way to increase masculinity itself. But how much of the buzz is backed by science? Host Rachel Feltman talks with journalist Stephanie Pappas about the realities behind the trend. They explore who truly benefits from TRT, the overlooked risks—including fertility loss—and the rise of private clinics offering testosterone.
