Nature: "Brain scans reveal how LSD affects consciousness"
We found that under LSD, compared to placebo, disparate regions in the brain communicate with each other when they don’t normally do so. In particular, the visual cortex increases its communication with other areas of the brain, which helps explain the vivid and complex hallucinations experienced under LSD, and the emotional flavour they can take.
On the other hand, within some important brain networks, such as the neuronal networks that normally fire together when the brain is at rest, sometimes called the ‘default mode network’, we saw reduced blood flow — something we’ve also seen with psilocybin — and that neurons that normally fire together lost synchronization. That correlated with our volunteers reporting a disintegration of their sense of self, or ego. This known effect is called ‘ego dissolution': the sense that you are less a singular entity, and more melded with people and things around you. We showed that this could be experienced independently of the hallucinatory effects — the two don’t necessarily go together...

"Man hacked random-number generator to rig lotteries":
A lottery security director who was convicted of fixing a $16.5m lottery jackpot also allegedly rigged several other lottery random-number generators to be able to predict the winning numbers, according to Iowa investigators.
For several years, Eddie Tipton, the former security director of the US Multi-State Lottery Association, installed software code that allowed him to predict winning numbers on specific days of the year, investigators allege. The random-number generators had been erased, but new forensic evidence has revealed how the hack was apparently done.
Tipton was convicted last year of rigging the $16.5m jackpot in Iowa, and is now awaiting trial on charges linking him to prizes in Colorado, Wisconsin, Oklahoma and Kansas.

Forbes: "What To Do When You Catch A Liar".
One interesting tidbit:
One interesting tidbit:
[I]t’s critical to take steps to protect yourself. One way to do that is to have a witness attest to what the liar said. Failing this, interact with the liar via email or text, both of which create a written record.
Though if you’re dealing with a particularly savvy liar, they’re not going to commit to anything in writing. In that case, document the conversation yourself: who, what, when, where, etc., and cap it off by sending your lying colleague an email summarizing the conversation. That’s not as good as having proof in the other person’s words, but at least you’ll be able to make the argument that your colleague had the opportunity to correct you...
