Two avenues for this are by using animal cells in a lab, or going plant-based. Two breakthroughs in this field of food science were published in journals recently: the...

Being able to belt out a tune like Adele or Pavarotti is not just about raw talent. The best singers in the world have to work on their technique—like how to control their breath and develop the stamina to hit note after note for a two-hour concert. But pop stars and opera singers aren’t the only vocalists who have figured out how to harness their voices for maximum impact. Death metal vocalists a...

It’s zombie season! At least if you’re watching the new season of the fungal thriller “The Last of Us,” airing right now on Max, which chronicles what happens after a fungus turns most of humanity into zombies. It’s fiction for us, but for some organisms on the planet, it’s more like a documentary. The fungus that zombifies humanity in the show is based on Ophiocordyceps , a real fungal group that...

Research suggests that better understanding the psychological and neurological components of chronic pain may lead to better treatments. Chronic pain is remarkably common: Roughly 20% of adults in the US live with it. And people with chronic pain are more likely to have depression, anxiety, and substance abuse disorders. But this relationship between physical and mental health is not as straightfo...

Researchers isolated one kind of cone in the eye and aimed lasers at it to allow subjects to see a super vibrant teal shade they call “olo.”Think about the colors of the world around you—the blue of a cloudless sky, the green of a new leaf, the blazing red of a tulip’s petals. We see these colors because of the way our eyes work. But what if we could change how our eyes respond to light, and prese...

How will market uncertainty and a lack of federal support for climate efforts affect the future of clean energy in the United States?

With the help of cat owners, a new project investigates cats’ biology and aims to link some of their behaviors to their genes. Calling all cat people: This one’s for you. Despite humans’ long history of welcoming felines into their homes and delis, research on cats lags far behind research on dogs. Now, scientists behind the project Darwin’s Ark are working to close the cat gap by enlisting cat ca...

An evolving technology is changing the lives of people with paralysis: brain-computer interfaces (BCI). These are devices that are implanted in the brain and record neural activity, then translate those signals into commands for a computer. This allows people to type, play computer games, and talk with others just by thinking, allowing more freedom to communicate. For decades, this technology has...

Are traffic engineering decisions based on evidence-based research? Not as much as you might think. If you’ve seen a car crash on the side of the road, you might look at it and think that the person at fault is the driver. But how much blame should be shared by the people who designed those roads in the first place? Well, some traffic engineers are calling for the field to accept more blame for th...

The Webb Space Telescope picked up traces of dimethyl sulfide on planet K2-18b. On Earth, the molecule comes from microbes and phytoplankton.
