We Now Have Artificial Embryos So Life-Like, They Initiate Pregnancy In Mice
Researchers have successfully mimicked the blastocyst stage of development in an artificial embryo created using stem cells.
The First Exoplanet Known to Contain Helium Is a Truly Alien World
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.

Tiny satellites named Wall-E and Eva are about to take a trip to Mars. Will they survive?
But if the tiny satellites do successfully work, similar low-cost satellites could be sent to other distant planets and moons, making communication with Earth from these deep reaches of space easier, and in some cases, possible at all.
When NASA lands a spacecraft on another planet, scientists generally need to have a “relay satellite” to beam images and measurements back to Earth.
Space exploration is hugely expensive, and cubesats could provide a much cheaper way to relay this information back home, rather than building and launching heavy spacecraft.
Undoing Aging 2018 – Dr. Nichola Conlon
Today, we have an interview with Dr. Nichola Conlon, one of the speakers at the Undoing Aging 2018 Conference in Berlin, hosted by the Forever Healthy Foundation and SENS Research Foundation.
Introducing Nuchido
Dr. Conlon is the CEO of Nuchido, a new company that is set to launch later this year and was encouraged in part by four recent breakthroughs in biogerontology, which each showed rejuvenation in mammals [1–9]. These studies, which were all published in leading peer-reviewed scientific journals, showed that rejuvenation of aged animals was possible via different mechanisms of action.
Stephen Hawking’s Final Theory About Our Universe Has Just Been Published, And It Will Melt Your Brain
Posthumous journal.
Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.
The paper, published today in the Journal of High Energy Physics, puts forward that the Universe is far less complex than current multiverse theories suggest.
It’s based around a concept called eternal inflation, first introduced in 1979 and published in 1981.
