In chimpanzee societies, a whistle followed by a high-pitched hoot seems to mean, “I’m leaving.” Energetic grunts probably say “good food.” And a hip thrust could signal that chimp is ready to get frisky.
These rough translations result from decades of research on chimp communication. In addition to revealing what apes are saying (big surprise: food and sex), the results also reflect why and how chimps communicate — and how this ...read more
An older version of an ultra-stable ytterbium lattice atomic clock at NIST. Ytterbium atoms are generated in an oven (large metal cylinder on the left) and sent to a vacuum chamber in the center of the photo to be manipulated and probed by lasers. Laser light is transported to the clock by five fibers (such as the yellow fiber in the lower center of the photo). (Credit: Burrus/NIST)
Time, like money, only seems important when it’s running out. But to physicists, time is always a big deal ...read more

More than 800 women die every day from complications during pregnancy and childbirth. Part of the reason for this is that scientists still don’t well understand how the placenta works, including how it is implanted into the uterus during a pregnancy.
Now, researchers from the University of Cambridge have created mini-placentas that grow in a dish. The advance provides researchers the ability to study how the placenta works in the lab, with the ...read more

HONG KONG — Chinese researcher He Jiankui, who claims to have edited the genomes of twin infant girls to protect them from HIV while they were embryos, presented his work today at a conference at the University of Hong Kong.
The controversial claim was first reported Sunday by the The Associated Press and through a series of YouTube videos, though no pape ...read more

England’s Royal Society, the national academy founded in November 1660, is still churning out loads of scientific excellence. In this blog, a current fellow shares how we can all help combat climate change.
On Nov. 28, 1660, English scientist Christopher Wren spoke at Gresham College in Central London, launching what is n ...read more

This fall, students everywhere were treated to a citizen science virtual field trip organized by Discovery Education and the Girl Scouts of the USA. “Unleash Your Inner Scientist,” the title of virtual field trip, featured SciStarter’s Founder, Darlene Cavalier, and was filmed on location at the 92-acre STEM Center of Excellence in Dallas, Texas. No worries if you missed it when it originally aired because the full-length virtual field trip video ...read more

Polio once paralyzed more than 350,000 people each year worldwide. Today, vaccines have dropped the number of reported cases to just 407 in 2013, according to the CDC.
But the disease still lurks in developing countries because vaccine storage and transport requires refrigeration. Now, scientists find freeze-d ...read more

Groundbreaking CubeSats
Yesterday, NASA’s InSight lander touched down successfully on the martian surface in a flawless feat of engineering.
Two briefcase-sized satellites known as CubeSats followed the exploratory probe all the way from Earth to the Red Planet. These twin Cubesats are the first of their kind to ever travel to ano ...read more
The fiery behavior of a star can be observed as sound waves. A pair of astronomers has built an AI network to better study stars using these sound waves. (Credit: NASA)
Star Sound Waves
Using artificial intelligence (AI) and sound waves, researchers have found a possible means of looking inside stars.
It’s based on the fact that stars aren’t solid objects — far from it, in fact. They’re intense, vibrating balls of plasma held together by their own gravity and with ...read more
Planet Nine could be lurking in the outer solar system, or it could join the ranks of other discredited planets. (Credit: Caltech/R. Hurt (IPAC)
In 2016, astronomers announced there was a new planet in the outer solar system. Planet Nine, supposedly larger than Neptune and located far beyond the orbits of the planets known so far, is a particular mystery since no one has yet observed it. Scientists have merely tracked its supposed orbit by watching the gravitational pull th ...read more
