Scientists Determine ‘Oumuamua Isn’t Made From Molecular Hydrogen Ice After All
The debate over the origins and molecular structure of ‘Oumuamua continued with an announcement in that despite earlier promising claims, the interstellar object is not made of molecular hydrogen ice after all.
Summary: Variations of CD38, a gene associated with attachment behaviors in humans and animals, may play a key role in relationship behaviors and perceptions that support bonding.

Variations in a gene called CD38, which is involved in attachment behaviour in non-human animals, may be associated with human romantic relationship dynamics in daily life, according to a study published in Scientific Reports.
First and foremost, I would likd to reiterate that Elon Musk is not motivated by money. Elon Musk uses his wealth to make a difference to mankind. Yes he makes billions (and deservedly) but he invests his billions for other projects too. From Tesla to Neuralink; from Starlink to The Boring Company. And for me the ever exciting SpaceX. My only wish is I live long enough to witness his many inventions and projects.
Four months ago when I did the video below and predicted that Elon Musk would be the World’s First Trillionaire, most people laughed and ridiculed the video especially as at that time Elon was only the 35th Richest Man in the World with a net worth of around the $30 Billion mark.
Fast forward four months later, Elon has added another £57.2 Billion to his net worth. And from 35th to 4th richest person in the world.
Imagine being the world’s first Trillionaire overcoming Jeff Bezos. What further projects will Elon do to advance the development of mankind. I for one, can’t wait.
A team of Harvard astronomers have a wild new theory: the Sun used to have a companion star, making our solar system a binary one during its ancient history.
The astronomers say the theory could explain the formation of the Oort cloud, a theoretical cloud of dust and smaller objects in the distant regions of our solar system that many believe was created out of the left overs from the early solar system.
In a new preprint submitted last month to the preprint archive arXiv, the team suggests that the Sun used to have a long lost binary star companion. Such a system could explain how some objects were scattered to the far reaches of the solar system, sometimes even making it to neighboring systems and vice versa.
“Previous models have had difficulty producing the expected ratio between scattered disk objects and outer Oort cloud objects,” Amir Siraj, a Harvard undergraduate student involved in the research, said in a statement. “The binary capture model offers significant improvement and refinement, which is seemingly obvious in retrospect: most Sun-like stars are born with binary companions.”
A binary star system would be far more likely to capture the Oort cloud.
Aubrey interviewed by, um, alien scientists.
Our conversation covers the importance of non-academic institutions in science, strategies for combating for repair the damage of aging, and an exploration of how extending human lifespan will change the Earth. In Dr. de Gray’s perspective, age-related decline is a medical problem like any other that can be treated and cured by cutting edge technology. He’s devoted himself to this pursuit as a founder of the SENS Research Foundation, the Methuselah Foundation, and the medical startup AgeX.

There is little in the way of law or custom to restrain this new arms race. Alarmed by the risks, several groups of diplomats and lawyers are trying to change that, and work out how to extend the laws that cover Earth-bound war into orbit.
Experts want to clarify how the laws of war on Earth apply beyond it.
Valuing diversity leads to scientific excellence, the progress of science and, most importantly, it is simply the right thing to do. We must value diversity not only in words, but also in actions.

What if I were to tell you that passwords could be replaced by 1,000 trillion atoms to create an unclonable ID tag? Yeah, that.
Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put the brakes on light particles, or photons, it would open the door to a host of new technology applications.
Now, in a paper published on Aug. 17, in Nature Nanotechnology, Stanford scientists demonstrate a new approach to slow light significantly, much like an echo chamber holds onto sound, and to direct it at will. Researchers in the lab of Jennifer Dionne, associate professor of materials science and engineering at Stanford, structured ultrathin silicon chips into nanoscale bars to resonantly trap light and then release or redirect it later. These “high-quality-factor” or “high-Q” resonators could lead to novel ways of manipulating and using light, including new applications for quantum computing, virtual reality and augmented reality; light-based WiFi; and even the detection of viruses like SARS-CoV-2.
“We’re essentially trying to trap light in a tiny box that still allows the light to come and go from many different directions,” said postdoctoral fellow Mark Lawrence, who is also lead author of the paper. “It’s easy to trap light in a box with many sides, but not so easy if the sides are transparent—as is the case with many Silicon-based applications.”
