New AI software may be used to help companies hire or fire employees

Posted by in category: robotics/AI

In the past, companies have often used technology to keep track of employee actions and increase productivity. But recently, they’ve begun using AI for hiring, firing and compensation.

Xander, which is developed by tech firm Ultimate Software, is being used at steel processor SPS Companies in Manhattan, Kansas, the Journal noted.

NASA’s planet-hunting spacecraft TESS moves closer to launch

Posted by in category: satellites

NASA is now just weeks away from launching its next mission to find undiscovered worlds beyond our solar system.

In a press conference Wednesday afternoon, the space agency revealed its Transiting Exoplanet Survey Satellite (TESS) is undergoing the final preparations in Florida ahead of its April 16 launch.

The Alt Rocket Tech That May One Day Take Humans to Mars

Posted by in category: space travel

A one-way trip to Mars with conventional chemical rockets could take up to nine months. It’s a long time for humans to be in a spaceship exposed to radiation and other hazards. That’s one reason NASA, space agencies, universities, and private industry are pursuing different rocket technologies. Here’s a look at them.

Are there extra dimensions lurking at the quantum scale?

Posted by in categories: nanotechnology, quantum physics

Some theories suggest there could be many more dimensions that we’re unaware of, mostly because they’re imperceptibly tiny. Now researchers have taken the search for extra dimensions down to the nanoscale, using a neutron beam to study gravitational forces more precisely than ever before.

The workplace of the future

Posted by in categories: business, economics, employment, robotics/AI

The march of AI into the workplace calls for trade-offs between privacy and performance. A fairer, more productive workforce is a prize worth having, but not if it shackles and dehumanises employees. Striking a balance will require thought, a willingness for both employers and employees to adapt, and a strong dose of humanity.

ARTIFICIAL intelligence (AI) is barging its way into business. As our special report this week explains, firms of all types are harnessing AI to forecast demand, hire workers and deal with customers. In 2017 companies spent around $22bn on AI-related mergers and acquisitions, about 26 times more than in 2015. The McKinsey Global Institute, a think-tank within a consultancy, reckons that just applying AI to marketing, sales and supply chains could create economic value, including profits and efficiencies, of $2.7trn over the next 20 years. Google’s boss has gone so far as to declare that AI will do more for humanity than fire or electricity.

Such grandiose forecasts kindle anxiety as well as hope. Many fret that AI could destroy jobs faster than it creates them. Barriers to entry from owning and generating data could lead to a handful of dominant firms in every industry.

Earth Likely Had Water Before Moon-Forming Smashup

Posted by in category: space

New research suggests that the moon-forming impact of another body and Earth, early in the solar system’s history, fully scrambled the two objects, and that water was already present before the smash-up.

Asteroids to serve as refuelling stations for space exploration

Posted by in categories: business, space travel

Many asteroids are rich in minerals, metals and water, making them potential life support systems for humans venturing deep into the solar system.

“Asteroids contain all the materials necessary to enable human activity,” says Peter Stibrany, chief business developer and strategist of California-based Deep Space Industries (DSI). “Just those near Earth could sustain more than 10bn people.”

Moreover, their relatively small mass means their gravitational field is weak, so in this respect, at least, they are much easier than larger bodies such as the moon to land on and leave, he argues.
