Hypertension is an increasingly encountered condition in modern society, as sedentary lifestyles, poor diet, and other unhealthy lifestyle choices are becoming more prevalent.

The aging processes generally cause our blood pressure to rise, as they steadily clog our arteries, stiffen blood vessels, and cause our hearts to work harder to get blood to all our tissues. However, the rate at which this happens is subject to a great deal of variation, and diet and lifestyle are two big influences on this. At least initially, hypertension is frequently self-inflicted and something that we can reverse to a certain extent, as a new study shows.

Researchers have recently demonstrated that a program seeking to help people change their lifestyles through diet and exercise was almost as effective as some medications for reducing blood pressure.

As the Equifax hack last year showed, there’s a lack of legislation governing what happens to data from a breach. And ultimately, a breach of genetic data is much more serious than most credit breaches. Genetic information is immutable: Vigna points out that it’s possible to change credit card numbers or even addresses, but genetic information cannot be changed. And genetic information is often shared involuntarily. “Even if I don’t use 23andMe, I have cousins who did, so effectively I may be genetically searchable,” says Ram. In one case, an identical twin having her genetic data sequenced created a tricky situation for her sister.

This week, DNA testing service MyHeritage revealed that hackers had breached 92 million of its accounts. Though the hackers only accessed encrypted emails and passwords — so they never reached the actual genetic data — there’s no question that this type of hack will happen more frequently as consumer genetic testing becomes more and more popular. So why would hackers want DNA information specifically? And what are the implications of a big DNA breach?

One simple reason is that hackers might want to sell DNA data back for ransom, says Giovanni Vigna, a professor of computer science at UC Santa Barbara and co-founder of cybersecurity company Lastline. Hackers could threaten to revoke access or post the sensitive information online if not given money; one Indiana hospital paid $55,000 to hackers for this very reason. But there are reasons genetic data specifically could be lucrative. “This data could be sold on the down-low or monetized to insurance companies,” Vigna adds. “You can imagine the consequences: One day, I might apply for a long-term loan and get rejected because deep in the corporate system, there is data that I am very likely to get Alzheimer’s and die before I would repay the loan.”

A case of plague has been diagnosed in Idaho, but you don’t need to cancel your trip to Boise just yet. This is not the first time plague has cropped up in the United States, and it probably won’t be the last. And officials know what to do when a case does pop up.

The diagnosis is devastating and you look for anything that’s going to give you hope.

Remote deterministic spin–spin entanglement is achieved using nitrogen–vacancy centres in diamonds and a single-photon entangling protocol, with much improved entangling rates compared to previously used two-photon protocols.

The connection between food and memory is one of those fundamentally human experiences we can all relate to. A compelling new study from the University of Southern California has revealed an intriguing explanation behind this phenomenon, and it illustrates how strongly the “second brain” in our gut communicates with our brain.

Inside our gastrointestinal tract lies a massive mesh of neurons often referred to as our “second brain.” While this neuronal control system primarily works to independently manage our digestive system, it also has been found to directly communicate with the brain via a long nerve, called the vagus nerve.

The vagus nerve has been found to mediate a great deal of metabolic communication between the gut and the brain. For example, one recent study revealed how feeding behavior, modulated by activity in the hippocampus, is directly activated by vagal nerve stimulation, mediated by signals from the gastrointestinal tract.

Speaking of Pangaea, this video shows how the present-day continents came to be formed from the Pangaea supercontinent about 240 million years ago, then shows what the Earth’s surface might look like 250 million years in the future, if the tectonic plates continue to move in predictable ways.

I hope this explanation is helpful. Of course all of this is scientific speculation, we will have to wait and see what happens, but this is my projection based on my understanding of the forces that drive plate motions and the history of past plate motions. Remember: “The past reveals patterns; Patterns inform process; Process permits prediction.”
