The new Mayflower, set to traverse the Atlantic in 2021, won’t bear any pilgrims. It’s a robot boat, sailing sailor-free.

SAN BENITO — Willie Rosales Jr. grew up in San Benito, and he never imagined the Valley would become a hub for space travel.
Inspired by all the SpaceX rocket activity near Boca Chica Beach, along with Elon Musk’s vision for the area, Rosales decided to turn his home into a tribute.
“My intentions are for travelers to visit San Benito, and I wanted to pay homage to Elon Musk,” he said.
As Elon Musk and Jeff Bezos rocket companies lead a new space race, NASA is working on AI and robotics to farm space plants and feed interplanetary humans.
One of my favorite science fiction authors is/was Isaac Asimov (should we use the past tense since he is no longer with us, or the present tense because we still enjoy his writings?). In many ways Asimov was a futurist, but — like all who attempt to foretell what is to come — he occasionally managed to miss the mark.
Take his classic Foundation Trilogy, for example (before he added the two prequels and two sequels). On the one hand we have a Galactic Empire that spans the Milky Way with millions of inhabited worlds and quadrillions of people. Also, we have mighty space vessels equipped with hyperdrives that can convey people from one side of the galaxy to the other while they are still young enough to enjoy the experience.
On the other hand, in Foundation and Empire, when a message arrives at a spaceship via hyperwave for the attention of General Bel Riose, it’s transcribed onto a metal spool that’s placed in a message capsule that will open only to his thumbprint. Asimov simply never conceived of things like today’s wireless networks and tablet computers and suchlike.
In this week’s edition of new unexplained astronomical phenomena, a team of astronomers led by Dr. Leigh Smith from Cambridge found a star 100 times larger than our sun that nearly disappears from the sky every few decades. They also have no idea why it does so.
The star, called VVV-WIT-08, is located 25000 light years away, and decreases in brightness by a factor of 30 rather than disappearing altogether. It’s not the first star to be discovered with this changing brightness pattern, but evidence is beginning to mount that this might just be another example of a new class of stars.
VVV-WIT-08’s name itself is calling out for an explanation. The “WIT” in the middle actually stands for “what is this”, which is what astronomers call stars that are difficult to classify into any particular established category.
In ‘Tsunami: The World’s Greatest Waves,’ two scientists chronical hundreds of eyewitness accounts to show the human cost of life at the water’s edge.
The search for life on exoplanets takes a fairly conservative approach. It focuses on life that is similar to that of Earth.
It’s time to think beyond “Earth-like” exoplanets and turn to some truly unusual places to find alien life: the exomoons of rogue planets in the Milky Way.
The plasticizers contained in many everyday objects can impair important brain functions in humans. Biologists from the University of Bayreuth warn of this danger in an article in Communications Biology. Their study shows that even small amounts of the plasticizers bisphenol A and bisphenol S disrupt the transmission of signals between nerve cells in the brains of fish. The researchers consider it very likely that similar interference can also occur in the brains of adult humans. They, therefore, call for the rapid development of alternative plasticizers that do not pose a risk to the central nervous system.
Bisphenols are plasticizers that are found in a large number of plastic products worldwide — for example, in food packaging, plastic tableware, drinking bottles, toys, tooth fillings, and babies’ dummies. In recent years, numerous health risks have already been associated with them, especially with bisphenol A (BPA). The Bayreuth research team led by Dr. Peter Machnik at the Animal Physiology research group (led by Prof. Dr. Stefan Schuster) has now for the first time investigated the effects of plasticizers on signal transmission between nerve cells in the adult brain. The study covers not only BPA, but also bisphenol S (BPS), which is often considered less harmful to health. Their findings: Both plasticizers impair communication between the nerve cells of the brain.
