Science Friday

News & Information: Sat • 11am-1pm
  • Hosted by Ira Flatow

Yes, we know it's on Saturday but they wouldn't change the name of the show for us ... we asked.  But we think it's a great program for Saturdays. Covering the outer reaches of space to the tiniest microbes in our bodies, Science Friday is the trusted source for news about science, technology, and other cool stuff. Each week host Ira Flatow mixes it up with people in the know and those who want to be.  It's brain fun, for curious people.

Bacteria are thriving in the sky — and they influence the weather

Ever since Antoni van Leeuwenhoek first observed “animalcules” through a microscope in the late 1600s, we’ve been finding bacteria all over. They’ve been discovered in deep sea vents, on human skin, and deep in Antarctic ice. There are even bacteria all the way up in the clouds. Strange and wonderful, no?

There's a sweet new test for pee in the pool

The artificial sweetener acesulfame potassium (ACE) can be found in everything from chewing gum, to baked goods, to the packets of sugar substitute on restaurant tables. But researchers at the University of Alberta recently made headlines with the announcement that they’d found ACE somewhere else: in 31 swimming pools and hot tubs.

Another way to grow crops — by laying down the plow

At a time when many modern farmers face problems like soil erosion, nutrient loss and drought, the black dirt on Doug Palen’s family farm is a field apart: Its health and texture just keep improving.

“Its organic matter continues to rise, and it just continues to perform even better than it did,” Palen says.

Here’s an unexpected story: Scientists are working on a drug to stimulate ear hair growth.

In this case, the ear hairs in question are actually tiny, sensory hair cells in our cochlea. We have about 15,000 of them in each ear, and they’re crucial to helping us detect sound waves. But the little cells are also very fragile.

New report gives cautious support for embryonic gene editing in humans

Last month, the National Academy of Sciences and the National Academy of Medicine released a report about the use of gene editing techniques like CRISPR on human embryos. The new report, coming from two globally respected scientific organizations, suggests the technique could be warranted in certain cases — not just in the laboratory, but in real life.

NASA was big on the internet in late February, when it announced that scientists had discovered seven Earth-sized exoplanets orbiting an ultra-cool dwarf star, 40 light-years away.

The planets are closer to their cool star than Mercury is to the sun, and scientists think they could all be temperate enough to hold liquid water — a key ingredient for life. Not surprisingly, the scientific community is abuzz about what the planets hold, water and otherwise.

Trump’s plan for the EPA is death by ‘a thousand cuts’

If President Donald Trump has his way, the Environmental Protection Agency will be downsized quite a bit: 31 percent, with more than 50 programs eliminated, as laid out in his budget proposal released on Thursday. But penny-pinching isn’t the only tool his administration and Republican lawmakers have at their disposal, to undermine the agency.  

As two environmental law experts explain, different congressional actions and executive orders can also be used to chip away at the EPA. Some already have.
