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
Insight’s first image of Mars. NASA.
NASA’s InSight lander reached Mars yesterday. It’s the seventh successful landed mission, and it’s the latest in our continuous presence on the red planet since 1997. Yup, we’ve had a rover or a lander doing science on Mars non stop for over 20 years! But landers like InSight don’t get enough love. They seem less exciting than their roving cousins, but these stationary missions have done some really incredible science. Reg ...read more
