Body cam footage of an Aurora, Colorado, cop tasing an unarmed black man in the back paved the way for the city to pay $110,000 to settle police abuse allegations, the man's lawyers told Ars Thursday.
Footage from September's tasing shows two black men being questioned by police who are responding to a weapons incident at a nearby apartment building. One of the men is seen and overheard on the video demanding to know why he's being questioned. "For what... ?" he says.
The research was conducted by Shoukhrat Mitalipov, the same guy who first cloned embryonic stem cells in humans. And came up with three-parent in-vitro fertilization.
Age may not be a state of mind, but the brain is definitely involved. That's the conclusion of a study published on Wednesday in the journal Nature, which provides compelling evidence that a specific structure in the brain, called the hypothalamus, plays a significant role in controlling the entire body's aging. The results suggest stem cells play a critical role, but only in part via their ability to generate new neurons.
The results come from researchers at the Bronx's Albert Einstein College of Medicine. They, along with several other labs, have generated evidence that suggested the hypothalamus played a key role in aging. That makes a certain amount of sense: aging is a systemic process, and the hypothalamus contains structures like the pituitary that release hormones that influence the entire body. And there's already been some indications that factors that control the dynamics of aging end up circulating through the blood.Aging and stem cells
But what controls the timing of aging? One intriguing possibility is that neural stem cells are involved. These stem cells continue to divide and produce new neurons even after the brain is fully developed, but their numbers appear to go down over time (possibly because more of them produce new neurons than are replaced by cell divisions). If the key factors are produced by neural stem cells, then their levels should go down over time, allowing aging to proceed.

After two serious accidents in 2015 and 2016, SpaceX has been on a tear in 2017 with 10 successful launches, including the historic re-flight of two used boosters and a used Dragon spacecraft. These achievements suggest the company is well on its way toward developing low-cost, reusable boosters, and therefore the rocket company founded by Elon Musk may be on the cusp of capturing much of the global launch market.
A new valuation appears to back up this optimism. According to the New York Times, SpaceX recently raised $350 million in additional funding, and during this process the company was valued at $21 billion. This represents a significant increase from 2015, when Google and Fidelity invested $1 billion in SpaceX, valuing the company at $12 billion.
The new report notes that the updated value of SpaceX places the company in rarefied air, as just six other venture-backed companies are valued at $20 billion or more around the world. These companies include US-based companies Uber, Airbnb, Palantir, and WeWork, as well as Chinese firms Didi Chuxing and Xiaomi.

Some four months after its initial release, Microsoft says it has opened the floodgates and is now pushing out Windows 10 version 1703, the Creators Update, to every compatible PC (a category that excludes systems using Intel's Clover Trail Atoms).
Earlier this month, AdDuplex, which tracks the penetration of the different Windows 10 versions, reported that as of July 18, the Creators Update had just passed 50 percent of Windows 10 systems. Forty-six percent are on the previous version, 1607 (aka the Anniversary Update).
Until now, the deployment of the Creators Update has been throttled to stage its rollout. That throttle is now removed, so most of that 46 percent should now start upgrading. Microsoft is also saying that with this full rollout, enterprise customers should have confidence deploying the update. With Microsoft getting rid of the "Current Branch" and "Current Branch for Business" nomenclature, this is the closest thing to a signal that the version is enterprise-ready.

In recent years, there has been a lot of interest in coupling sound and light together. Admittedly, we've been doing this for a long time, but we've always been limited in terms of what we can do with how nature puts materials together. Now, with our ability to construct structures that are the right size, we can make devices that really dance to the tune that we give them.
This control has been demonstrated in a very cute way recently. Researchers have put together micro pillars that convert light into long-lasting, very high-frequency sound waves.Nature leads the way
Nature, of course, allows sound and light to play together in different ways. For instance, if a gas absorbs light, it will heat up and expand, so flashing a light into a gas will generate a sound wave at the frequency of the flashing. One of the most sensitive techniques for measuring how materials absorb light makes use of this.
