I am waiting for tricorders.

The idea of visiting the doctor’s office with symptoms of an illness and leaving with a scientifically confirmed diagnosis is much closer to reality because of new technology developed by researchers at McMaster University.

Engineering, biochemistry and medical researchers from across campus have combined their skills to create a hand-held rapid test for bacterial infections that can produce accurate, reliable results in less than an hour, eliminating the need to send samples to a lab.

Their proof-of-concept research, published today in the journal Nature Chemistry, specifically describes the test’s effectiveness in diagnosing urinary tract infections from real clinical samples. The researchers are adapting the test to detect other forms of bacteria and for the rapid diagnosis of viruses, including COVID-19. They also plan to test its viability for detecting markers of cancer.

SpaceX’s Texas facility known as Starbase has seen significant progress in its quest to become a mass-producing entity of Starship Super Heavy rockets.

In the last few weeks, SpaceX’s South Texas facility known as Starbase has seen significant progress in its quest to become a mass-producing entity of heavy-lift rockets.

Company founder and CEO Elon Musk recently shared a series of tweets showing the progress on the heavy-lift rocket known as Super Heavy in the company’s high bay assembly facility.

One of the tweets depicted the aft section of the giant rocket, known as BN2 or booster No. 2, seeming mostly completed in preparation for the company’s upcoming orbital attempt of the Starship launch system.

In an email, the company said that targeted devices included security appliances that have remote management or SSL VPN enabled, namely in the USG/ZyWALL, USG FLEX, ATP, and VPN series running on-premise ZLD firmware. The language in the email is terse, but it appears to say that the attacks target devices that are exposed to the Internet. When the attackers succeed in accessing the device, the email further appears to say, they are then able to connect to previously unknown accounts hardwired into the devices.

Batten down the hatches

“We’re aware of the situation and have been working our best to investigate and resolve it,” the email, which was posted to Twitter, said. “The threat actor attempts to access a device through WAN; if successful, they then bypass authentication and establish SSL VPN tunnels with unknown user accounts, such as ‘zyxel_silvpn,’ ‘zyxel_ts,’ or ‘zyxel_vpn_test,’ to manipulate the device’s configuration.”

Virgin Galactic announced on Friday that the Federal Aviation Administration granted the company the license it needs to fly passengers on future spaceflights, a key hurdle as the venture completes development testing.

“The commercial license that we have had in place since 2016 remains in place, but is now cleared to allow us to carry commercial passengers when we’re ready to do so,” Virgin Galactic CEO Michael Colglazier told CNBC. “This is obviously an exciting milestone and a huge compliment to the team.”

While the FAA previously gave Virgin Galactic a launch license to conduct spaceflights, the license expansion allows the company to fly what the regulator calls “spaceflight participants.” The company completed a 29 element verification and validation program for the FAA, clearing the final two FAA milestones with its most recent spaceflight test in May. Colglazier noted the two last milestones were specific to the spacecraft’s flight control systems and inertial navigation systems.

1. Bigelow must be pissed.

2. A giant ring like that would make a hell of a spacecraft to get around the solar system.

Lawrence Klaes shared a link to the group: Space Settlement Alliance.

The Orbital Assembly Corporation, a space construction firm run by NASA veterans, announced in a press statement today, June 24, that it has successfully demonstrated its technology for developing the world’s first space hotel.

Circa 2012 Dilithium crystal created.

Fusion Engine Space

Brace yourselves: Researchers at University of Huntsville in Alabama say they are using “Dilithium Crystals” in a new fusion impulse engine that could cut the travel time to Mars down to as little as six weeks, not the six months it takes now.

Txchnologist, an online magazine sponsored by General Electric, talked to team member and aerospace engineering PH.D. candidate Ross Cortez, he said “The fusion fuel we’re focusing on is deuterium [a stable isotope of hydrogen] and Li6 [a stable isotope of the metal lithium] in a crystal structure.”

“That’s basically dilithium crystals we’re using,” he said.

Last July, NASA successfully launched the Mars Perseverance rover into space. After traveling for 203 days and 300 million miles at the speed of about 24600 miles per hour, NASA Perseverance Rover landed on Mars on February 18, 2021. Today, the top speed ever reached by NASA ion thruster-powered spacecraft is 200000 mph.

So, what about if NASA wants to explore other planets like Proxima b which is 4.24 light-years away? Unfortunately, we can’t. The current rocket propulsion technology hasn’t changed significantly since it was originally developed in the 1920s. As astronaut Scott Kelly pointed out, it’ll take us 800000 years to get to the TRAPPIST-1 star system. However, with today’s current space propulsion technology.

Circa 2015 In theory this big bang laser could eventually create complex matter but would need to be pocket-size as I want it on a smartphone to make a replicator so I can make fruit or food in space 😀

The Institute of Laser Engineering (ILE), Osaka University, has succeeded to reinforce the Petawatt laser “LFEX” to deliver up to 2000 trillion watts in the duration of one trillionth of one second (this corresponds to 1000 times the integrated electric power consumed in the world). By using this high-power laser, it is now possible to generate all of the high-energy quantum beams (electrons, ions, gamma ray, neutron, positron). Owing to such quantum beams with large current, we can make a big step forward not only for creating new fundamental technologies such as medical applications and non-destructive inspection of social infrastructures to contribute to our future life of longevity, safety, and security, but also for realization of laser fusion energy triggered by fast ignition.

Background and output of research

Petawatt lasers are used for study of basic science, generating such high-energy quantum beams as neutrons and ions, but only a few facilities in the world have Petawatt laser. So far, Petawatt lasers in the world have had relatively a small output (to a few tens of joules). ILE has achieved the world’s largest laser output of dozens of times those at other world-class lasers facilities (1000 joules or more).
