Watch the First-Ever HD Footage of a Cell Moving Through the Body

Posted by in categories: biotech/medical, innovation

If you’re like most people, the first biological cell you ever saw was flat: a diagram in a book, or maybe a microscope image on a slide if you were lucky. Same goes for scientists. It’s hard enough to zoom in on something so small, much less capture a 3D image of the thing. As a result, it’s easy to imagine that there are a multitude of two-dimensional discs filling your blood vessels and fighting your infections. That’s why this new development is so eye-opening. Researchers have made an imaging breakthrough that lets them capture 3D footage of cells doing their thing inside the body — and it may look nothing like what you imagined.

The video below depicts the inner ear of a zebrafish — you know, that little inch-and-a-half (4-centimeter) striped thing you see in pet store fish tanks? Suffice it to say, the objects in this footage are very, very small. Here, a fiery yellow immune cell rolls on through gobbling up bright-blue particles of sugar.

The First Exoplanet Known to Contain Helium Is a Truly Alien World

Posted by in category: alien life

In addition to filling balloons at birthday parties, helium can be found scattered throughout the cosmos. To date, however, scientists have struggled to detect the ubiquitous element on distant worlds, even though the gas is certain to be there. But that’s now changed, thanks to the discovery of helium on a Jupiter-sized world located 200 light-years from Earth—but that’s only part of the story.

“Helium is the second-most common element in the universe after hydrogen. It is also one of the main constituents of the planets Jupiter and Saturn in our Solar System,” Jessica Spake, the astronomer who made the discovery, said in a statement. “However, up until now helium had not been detected on exoplanets—despite searches for it.”

But now, using Wide Field Camera 3 on NASA’s Hubble Space Telescope, Spake’s team managed to detect this strangely elusive substance, marking the first time that helium has been detected on a planet outside of our Solar System. The key to the finding was the use of infrared spectra to study the exoplanet’s atmosphere, whereas previous attempts used ultraviolet and optical wavelengths. This study now shows that the composition of exoplanetary atmospheres can indeed be studied at longer wavelengths. The details of this discovery were published yesterday in Nature.
