Forget rockets: This ‘space elevator’ could launch you into orbit

Posted by in category: space

A Canadian company has clinched a patent for a 12.4 mile-high “space elevator” that could launch astronauts and tourists into orbit.

The free-standing tower would essentially be inflated, supported by a series of gas-pressurized cells, and serve as a docking platform for space planes that could launch cargo, tourists and satellites directly into lower orbit.

Thoth Technology, the Ontario-based company behind the invention, told CNBC the elevator could transport 10 tons of cargo at approximately seven miles per hour, with passengers able to reach the top of the tower in about 60 minutes. Passengers could then board a space plane that could reach lower orbit without the need for costly a rocket launch.

First Near-Fully Formed Brain Grown In Lab, Ohio State Scientists Say

Posted by in categories: biotech/medical, neuroscience

Scientists at Ohio State University say they’ve grown the first near-complete human brain in a lab.

The brain organoid, if licensed for commercial lab use, could help speed research for neurological diseases and disorders, like Alzheimer’s and autism, Rene Anand, an Ohio State professor who worked on the project, said in a statement Tuesday.

Killing Cancer Through Overstimulation

Posted by in category: biotech/medical

Cancer requires extensive and fast division in order to become a serious threat, but this feature also renders it vulnerable, allowing certain growth pathways to be targeted. A new drug candidate has emerged which exploits this weakness, overstimulating proteins required for growth — tipping cellular stress in virulent cancer cells over the edge.

“No prior drug has been previously developed or proposed that actually stimulates an oncogene to promote therapy. Our prototype drug works in multiple types of cancers and encourages us that this could be a more general addition to the cancer drug arsenal.”

Many types of cancer require specific mutations in genes related to growth, and one particular target is the steroid receptor coactivator (SRC) family of oncogenes. These lie at the centre of signalling pathways used to grow rapidly, and conventional research has focused on inhibiting them to prevent tumour growth. Instead of inhibiting, this new strategy aims to upregulate their activity, overstimulating them to an extent that destroys the host cell. In their search for a suitable molecule which might cause such stimulation, researchers stumbled across a compound labeled MCB-613.

Samsung says we can achieve Earth-wide Internet via 4,600 micro-satellites

Posted by in category: internet

A new report from tech giant Samsung proposes that a fleet of roughly 4,600 micro-satellites orbiting Earth could solve our impending data crisis.

Predicting that by 2028, 5 billion Internet users around the world will be collectively chewing through at least 1 zettabyte per month — to put that in perspective, 1 zettabyte is 1,000 exabytes, 1 exabyte is 1,000 petabytes, and 1 petabyte is 1,000 terabytes — the report says we’re going to have to think seriously about how we can deliver that. A constellation of tiny Internet-beaming satellites could be a viable option, it says, and Samsung could be the one to build it.

The report, entitled Mobile Internet from the Heavens, describes an Internet satellite system that will avoid the latency issues of current communications satellites by being positioned much closer to Earth. “Most modern communications satellites live in geostationary orbit, roughly 35,000 kilometres above the surface, and this imposes a hard limit on speed due to travel time for the data transmissions,” Graham Templeton writes for ExtremeTech. “Samsung wants to position its constellation in Low Earth Orbit (LEO) and thus reduce this delay.”

Record-Breaking Laser Hits 2,000 Trillion Watts

Posted by in categories: energy, solar power, sustainability

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or one picosecond.

Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.

Cryptographers Develop Encryption Method Resistant to Future Quantum Attacks

Posted by in categories: computing, encryption, internet, quantum physics

Cryptographers are working on new encryption methods able to protect today’s Internet communications from future quantum computers that can be able to break today’s cryptography techniques. The researchers have developed upgrades to the Internet’s core encryption protocol that will prevent quantum computer users from intercepting Internet communications.
