A new type of nuclear reactor designed to power crewed outposts on the moon and Mars could be ready for its first in-space trial just a few years from now, project team members said.

A flight test is the next big step for the Kilopower experimental fission reactor, which aced a series of critical ground tests from November 2017 through March 2018. No off-Earth demonstration is on the books yet, but Kilopower should be ready to go by 2022 or so if need be, said Patrick McClure, Kilopower project lead at the Department of Energy’s (DOE) Los Alamos National Laboratory in New Mexico.

A remarkable new study from scientists at Stanford University has revealed thousands of previously undiscovered small proteins produced by bacteria in the human microbiome. Almost all of these newly described proteins serve unknown functions in the human body and the researchers suggest their discovery opens up a new frontier for future therapeutic drug development.

Security researchers from Google’s Project Zero team recently uncovered pre-installed apps in Android devices that either allowed remote attackers to carry out remote code execution, could disable Google Play Protect in devices, or could collect information on users’ web activities.

At the Black Hat cybersecurity conference in Las Vegas, Maddie Stone, a security researcher on Project Zero and who previously served as Senior Reverse Engineer & Tech Lead on Android Security team, revealed that her team discovered three instances of Android malware being pre-installed in budget Android phones in the recent past.

One such pre-installed app was capable of turning off Google Play Protect, the default mobile security app in Android devices, thereby leaving devices vulnerable to all forms of cyber attacks or remote surveillance. The Project Zero team also found an app pre-installed on Android phones that gathered logs of users’ web activities.

What. The. Heck. Did you see that? Simone Biles appears to defy the laws of physics with this epic tumbling pass from the 2019 US Gymnastics Championships. It’s called a triple-double. That means she rotates around an axis going through her hips twice while at the same time rotating about an axis going from head to toe THREE times. Yes, it’s difficult—but it doesn’t defy physics, it uses physics.

Today, we have to share some bad news about Organovo and its liver tissue bioprinting program.

Dark matter most likely makes up an incredible 80 percent of the universe’s mass. But this single fact is the extent of our knowledge about this mysterious, all pervasive substance, with scientists unsure exactly what it is and how it came to be. Now a groundbreaking study has revealed dark matter may be even more bizarre than first thought, as its origin may have actually pre-dated the beginning of the Universe – the Big Bang.

Growing evidence suggests that certain types of bacteria are capable of causing colorectal cancers, indicating that a sub-set of these cancers could be the result of infectious disease.

But understanding how bacteria interact in the human gut – our microbiome — has been challenging because of the complex microbial mixture of “good” and “bad” bacteria.

Over a decade ago, French scientists discovered a pathway in certain strains of E. coli, a bacterium normally found in 90% of humans, that is “genotoxic” – toxic to DNA – causing tumor formation and colorectal cancer in mice.

What is reality and how do we know? For many the answer is simple: What you see — hear, feel, touch, and taste — is what you get.

Your skin feels warm on a summer day because the sun exists. That apple you just tasted sweet and that left juices on your fingers, it must have existed. Our senses tell us that reality is there, and we use reason to fill in the blanks — that is, we know the sun doesn’t cease to exist at night even if we can’t see it.

But cognitive psychologist Donald Hoffman says we’re misunderstanding our relationship with objective reality. In fact, he argues that evolution has cloaked us in a perceptional virtual reality. For our own good.

If you want a vision of the future, imagine a thousand bots screaming from a human face – forever (apologies to George Orwell). As U.S. policymakers remain indecisive over how to prevent a repeat of the 2016 election interference, the threat is looming ever more ominous on the horizon. The public has unfortunately settled on the term “bots” to describe the social media manipulation activities of foreign actors, invoking an image of neat rows of metal automatons hunched over keyboards, when in reality live humans are methodically at work. While the 2016 election mythologized the power of these influence-actors, such work is slow, costly, and labor-intensive. Humans must manually create and manage accounts, hand-write posts and comments, and spend countless hours reading content online to signal-boost particular narratives. However, recent advances in artificial intelligence (AI) may soon enable the automation of much of this work, massively amplifying the disruptive potential of online influence operations.

This emerging threat draws its power from vulnerabilities in our society: an unaware public, an underprepared legal system, and social media companies not sufficiently concerned with their exploitability by malign actors. Addressing these vulnerabilities requires immediate attention from lawmakers to inform the public, address legal blind spots, and hold social media companies to account.
