Posted on September 23, 2021 by BrianKrebs

In October 2016, media outlets reported that data collected by some of the world’s most renowned cybersecurity experts had identified frequent and unexplained communications between an email server used by the Trump Organization and Alfa Bank, one of Russia’s largest financial institutions. Those publications set off speculation about a possible secret back-channel of communications, as well as a series of lawsuits and investigations that culminated last week with the indictment of the same former federal cybercrime prosecutor who brought the data to the attention of the FBI five years ago.

Salto the jumping robot can now execute stylish precision landings

Posted on June 11, 2020 by Loz Blain

This cute, one-legged hopping robot out of UC Berkeley’s Biomimetics lab has been capable of doing sweet parkour-style double-jumps off walls since 2016. By 2018, it was hopping continuously to heights up to a meter (3.3 ft) or so, with pretty decent a… Continue reading Salto the jumping robot can now execute stylish precision landings→

Hybrid reactor uses living bacteria to turn CO2 into useful molecules

Posted on April 1, 2020 by Nick Lavars

Were humans to one day make it to Mars, one of the problems we’d need to have solved long in advance is how to produce necessities like fuel and drugs without having to take them there ourselves. One way we could do this is by collecting carbon dioxide… Continue reading Hybrid reactor uses living bacteria to turn CO2 into useful molecules→
