A new model giving rise to young planetary systems offers a fresh solution to a puzzle that has vexed astronomers ever since new detection technologies and planet-hunting missions such as NASA’s Kepler space telescope have revealed thousands of planets orbiting other stars: While the majority of these exoplanets fall into a category called super-Earths—bodies with a mass somewhere between Earth and Neptune—most of the features observed in nascent planetary systems were thought to require much more massive planets, rivaling or dwarfing Jupiter, the gas giant in our solar system.
Stanford researchers have for the first time captured the freezing of water, molecule-by-molecule, into a strange, dense form called ice VII (“ice seven”), found naturally in otherworldly environments, such as when icy planetary bodies collide.
A discontinued vaccine against a bacteria that causes brain inflammation also shielded people against gonorrhea, the first drug ever to offer such protection against the sexually transmitted disease, researchers said Tuesday.
NASA’s Juno mission just hit a high point with a buzzing flyby on Monday night of one of Jupiter’s most notable features: the Great Red Spot, a massive spinning storm that is a focus of fascination for scientists and space fans. This is the closest Juno has been to the distinctive oval-shaped spot, which is twice as wide as Earth.
President Trump has just recently announced that the U.S. will not participate in the Paris Climate Agreement. He implied that he regarded it as a bad deal for the U.S. economy, while not necessarily disputing its premise that man’s use of fossil fuels was going to cause a disastrous deterioration of the Earth’s climate.
“Your email was blocked, we’ve contacted an HR representative.”
This message could go a long way towards weeding out some of the sexual explicit messaging in the workplace, most recently highlighted by a New York Times report.
Although it would by no means block all suggestive comments that occur in the workplace, there is a way to make an artificial intelligence (AI) become more aware of what is happening in the digital realm.
The Moon is the Tango to Earth’s Cash, the Hall to our Oates, the Lennon to our McCartney before they hated each other. Simply put, our planet and the Moon are soul mates: except, of course, if something were to happen to one of them. Like, I don’t know, what if we just blew up the Moon?
Six years ago, climatologist Dr. Tim Ball challenged the data and scientific methodology of Michael E. Mann’s (in)famous “hockey-stick” temperature graph. As did several other climate observers. But for his harshest critics, Mann took the unusual step of suing them for libel.
Ball, a Canadian citizen, wrote an op-ed in which he wrote that Mann “belongs in the state pen, not Penn State.” The suit alleged that Ball’s statements were factually untrue and defamatory.
Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known.
