Here’s a simple how-to on how to construct a traversable cosmic wormhole that could send your spaceship to the furthest reaches of space: take two charged black holes, place them back to back, and thread two cosmic strings through both. Stretch both strings to infinity and presto! You’ve got yourself a traversable wormhole. Confused yet?

Third Kuaizhou-1A mission follows a period of new companies and light launch vehicles reaching the pad and competing for limited commercial contracts in China. HELSINKI — A commercial Kuaizhou-1A rocket launched two satellites late Friday, continuing a recent intense period of light launch vehicle activity in China. The Kuaizhou-1A launched from a mobile platform at
This photo provided by the National Hurricane Center shows a view of Hurricane Dorian from Hurricane Hunter P-3 Aircraft early Saturday, Aug. 31, 2019. Dorian has gained fearsome new muscle as an “extremely dangerous” Category 4 storm, bearing down ASSOCIATED PRESS As of this writing, Hurricane Dorian is a category 4 storm churning towards the
It was supposed to be extinct by now. The invasive tumbleweed Salsola ryanii only popped up on scientists’ scopes in 2002, but early research concluded it was nothing to worry about. A 2008 study predicted S. ryanii wouldn’t easily adapt, nor be able to expand its range. Those predictions have not aged well. Since the
Back in 2017, neuroscientists used a classic branch of maths in a totally new way to peer into the structure of our brains. What they discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions. We’re used to thinking of the world from a 3-D perspective, so
Last Wednesday, a gravitational wave detection gave astronomers quite the surprise. As researchers were going about their work at the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of gravitational waves rolled in just minutes apart. The first, labelled S190828j, was picked up by all three of LIGO’s gravitational wave detectors at 06:34 am, coordinated universal time. The
WASHINGTON — Orbion Space Technology announced Aug. 28 it raised a $9.2 million Series A round to develop and mass produce Hall-effect plasma thrusters for small satellites. Material Impact, a venture capital firm focused on early-stage investments, led the round, with Invest Michigan, Invest Detroit, Wakestream Ventures, Ann Arbor Spark, and Boomerang Catapult also participating.

We’re sure you have your favourite animal. It may even be a really smart one. But corvids – such as crows, magpies and ravens – really are something special. In fact, they’re some of the most intelligent animals in the world. And here we’ve gathered some of the finest examples of just how clever these
What comes to mind when you hear the words “artificial intelligence”? Perhaps you think of Apple’s digital assistant, Siri, or Rosie the Robot from The Jetsons? Perhaps you think of Haley Joel Osment as a robot boy in the 2001 film, AI? Elon Musk thinks you’re looking at it all wrong. “I think generally people
If all the hydro-power dams in the United States were removed and replaced with solar panels, it would take up a fraction of the land and produce substantially more electricity, according to a new analysis. The idea is ambitious, and for now, it’s really just a thought experiment. Today, hydropower is a significant source of
WASHINGTON — Japanese satellite operator Sky Perfect JSAT said it is focusing on a wide range of growth initiatives as fiber optic cable expansion and smartphone video viewing habits make its satellite broadcasting business increasingly difficult. JSAT has lost more than half a million satellite television subscribers since 2013, when that business reached 3.83 million
Brands are beginning to realize the power of incorporating diversity and inclusivity in their marketing and product development. Cadbury Cadbury At Adobe Annual Conference in 2018, Matt May, Adobe’s head of inclusive design, stressed that “the time is now to rethink how designers create products with diversity and inclusion in mind.” Most recently, I have seen a new
WASHINGTON (Reuters) – Artifacts including stone tools and animal bone fragments found in Idaho dating back about 16,600 years represent what may be the oldest evidence of humans in the Americas and offer insight into the routes people took as they spread into the New World. Excavation work by scientists at the Cooper’s Ferry archaeological
WASHINGTON — Members of the InSight mission team are using a break in spacecraft operations to study new ways to get one of the spacecraft’s key instruments to resume burrowing into the Martian surface. Scientists and engineers involved with InSight’s Heat Flow and Physical Properties Package instrument have been working for the last several months
Maj Gen Nina Armagno, Director of Space Programs for the Secretary of the Air Force United States Air Force Success in space is much like that in any team sport: every team member, from the most senior leader to the newest hire, must relentlessly pursue contradictory values, individual excellence and commitment to team goals. Because
Given the extravagant profusion of moons in our own Solar System, it seems likely that there are way more exomoons out there in the Universe than there are exoplanets. We’re yet to conclusively find one – but astronomers just found a signal that could mean the presence of an exomoon. Not just any exomoon, either,
The brain is the ultimate computing machine, so it’s no wonder researchers are keen to try and emulate it. Now, new research has taken an intriguing step in that direction – a device that’s able to ‘forget’ memories, just like our brains do. It’s called a second-order memristor (a mix of “memory” and “resistor”). The clever
LONDON (Reuters) – A large scientific study into the biological basis of sexual behavior has confirmed there is no single “gay gene” but that a complex mix of genetics and environment affects whether a person has same-sex sexual partners.

WASHINGTON — NASA’s partners in the International Space Station remain committed to participating in the lunar Gateway despite changes to the program earlier this year that could delay their contributions to the outpost. In an Aug. 28 statement, members of the station’s Multilateral Coordination Board (MCB), which includes the five space agencies involved in the
