At any given moment, thousands of satellites swarm over our heads at altitudes ranging between a few hundred miles and tens of thousands of miles.

But, of the manmade items in space that are larger than your fist, orbiting satellites are a minority. About 95% of what’s out there is space junk: out-of-control space stations, used rocket parts, dead satellites, lost astronaut tools and more.
The vast majority of this week’s episode focused on psychological drama, but the major events of the episode were bookended by a bit of Elliot’s (or is it Mr. Robot?) hacking ingenuity. Let’s take a peek.
It is good to be paranoid when it comes to cybersecurity.
Google already provides various advanced features such as login alerts and two-factor authentication to keep your Google account secure.

However, if you are extra paranoid, Google has just introduced its strongest ever security feature, called "Advanced Protection," which makes it easier for users, who are usually at high risk of targeted online attacks, to lock down their Google accounts like never before.
Do you think your wireless network is secure because you're using WPA2 encryption?

If yes, think again!

Security researchers have discovered several key management vulnerabilities in the core of Wi-Fi Protected Access II (WPA2) protocol that could allow an attacker to hack into your Wi-Fi network and eavesdrop on the Internet communications.
The psychedelic compound 5-MeO-DMT decreased proteins associated with inflammation and degeneration in neural-cell cultures.

The proteins in our brain associated with learning and memory function can be increased, while the proteins associated with inflammation and brain lesion can be decreased, with use of the psychedelic compound 5-MeO-DMT.

In a study published in the journal Scientific Reports, researchers from Brazil’s D’Or Institute exposed cerebral organoids, 3D cultures of neural cells that act like miniature human brains, to one dose of 5-MeO-DMT and observed the effects.
Oxford in the UK wants to become the world's first carbon emission-free city by 2035, with a plan to ban all petrol and diesel vehicles from the city centre over the next 20 years. The initiative will run in phases, with the first restrictions coming into place in 2020.

The move is partly a response to the levels of nitrogen dioxide (NO2) in the centre of Oxford, levels which have been dropping but remain dangerously high – the gas is produced by burning fuel and causes breathing difficulties and other respiratory problems.
Remember NotPetya?

The Ransomware that shut down thousands of businesses, organisations and banks in Ukraine as well as different parts of Europe in June this year.

Now, Ukrainian government authorities are once again warning its citizens to brace themselves for next wave of "large-scale" NotPetya-like cyber attack.
