Humans Still Evolving, Large-Scale Study of Genetic Data Shows

In a study analyzing the genomes of 210,000 people in the United States and Britain, researchers have found that the genetic variants linked to Alzheimer’s disease and heavy smoking are less frequent in people with longer lifespans, suggesting that natural selection is weeding out these unfavorable variants in both populations. “It’s a subtle signal, but we find genetic evidence that…

Our Brains Have A Basic Algorithm That Enables Our Intelligence, Scientists Say

Our brains have a basic algorithm that enables us to not just recognize a traditional Thanksgiving meal, but the intelligence to ponder the broader implications of a bountiful harvest as well as good family and friends. “A relatively simple mathematical logic underlies our complex brain computations,” said Dr. Joe Z. Tsien, neuroscientist at the Medical College of Georgia at Augusta University,…

Unlocking Big Genetic Data Sets

The same algorithms that personalize movie recommendations and extract topics from oceans of text could bring doctors closer to diagnosing, treating and preventing disease on the basis of an individual’s unique genetic profile. In a study to be published Monday, Nov. 7 in Nature Genetics, researchers at Columbia and Princeton universities describe a new machine-learning algorithm for scanning massive genetic…

Using big data, scientists discover biomarkers that could help give cancer patients better survival estimates

People with cancer are often told by their doctors approximately how long they have to live, and how well they will respond to treatments, but what if there were a way to improve the accuracy of doctors’ predictions? A new method developed by UCLA scientists could eventually lead to a way to do just that, using data about patients’ genetic…

We Know Where You Live – From Location Data Alone, Even Low-Tech Snoopers Can Identify Twitter Users’ Homes, Workplaces.

Researchers at MIT and Oxford University have shown that the location stamps on just a handful of Twitter posts — as few as eight over the course of a single day — can be enough to disclose the addresses of the poster’s home and workplace to a relatively low-tech snooper. Twitter’s location-reporting service is off by default, but many Twitter users…
