The Voyager 2 became just the second human-made object to enter interstellar space early last month. The Voyager 2 probe was launched in 1977 and is NASA’s longest-running mission operating for 41 years. The probe is carrying the unique Plasma Science Experiment Instrument which will allow the collection of unprecedented observations in interstellar space.
In a historic first a healthy baby was born using a womb transplanted from a dead body. While previous attempts were made the transplants failed or ended in miscarriage. The transplant and fertility treatment took place in 2016 in Brazil on a woman born without a womb. The baby was born last December.
He Jiankui the Chinese scientist who claims he created the world’s first genetically edited babies defended his work at a genome summit in Hong Kong. He announced the possibility of a third child being born following the twin girls born this month. The controversial gene editing program has been halted following international opposition.
After seven months of traveling through space, the NASA InSight mission has landed on Mars. A few minutes after landing, InSight sent the official “beep” to NASA to signal that it was alive and well, including a photo of the Martian surface where it landed. InSight, or Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is going to explore a part of Mars that the scientists know the least about: its deep interior.
Scientists decided to overhaul the way the kilogram is defined at the General Conference on Weights and Measures on Friday. The kilogram is currently defined by the weight of a platinum-based inglot called ‘Le Grand K.’ It will now be defined in terms of an electric current starting in May of 2019.
A frozen exoplanet which is three-times the mass of Earth was discovered orbiting a star six lightyears away. It orbits Barnard’s star and is the second closest exoplanet known to astronomers. A large impact crater was found under a half-mile thick Greenland ice sheet. It was created by a meteorite from 12,000 years ago.
A study published in The Lancet on Thursday says population continues to rise despite fertility rates having been cut in half since 1950. The study found that nearly half of the world’s countries are facing a ‘baby bust’ where there are not enough children to maintain population size. Other countries are experiencing a ‘baby boom.’
A study conducted by the Environment Agency Austria discovered the presence of microplastics in human stool for the first time. The study examined participants from Russia, Japan, and Europe and plastic was found in all samples. The study estimated that ‘more than 50% of the world’ could have microplastics in their stool.
A Russian rocket heading for a 6-month mission at the International Space Station failed on Thursday just about 100 seconds after liftoff in Kazakhstan causing an emergency landing. Russian cosmonaut Alexei Ovchinin and American astronaut Nick Hague were unharmed. Russian officials are investigating the booster issue that caused the Soyuz rocket to fail.
Scientists have discovered molecules of fat in fossilized remains of Dickinsonia, an ancient group of organisms, to reveal the earliest confirmed animal in the geological record that lived on Earth 558 million years ago. The new finding ends the scientific debate, whether it is an animal or fungi, over Dickinsonia since it was first discovered 75 years ago.
