When the Montreal Protocol phased out the use of chlorofluorocarbons starting in 1989, scientists expected to see improvements in the Antarctic ozone hole that was opening each spring. They weren't anticipating anything immediate—instead, improvement was expected within 20 to 30 years of the protocol’s implementation. Ozone recovery occurs through distinct stages, including a reduction in the rate of ozone decline and a leveling off of the depletion. Only once these are done should we expect to see an ozone increase, termed “ozone healing.”

Previous studies of the Antarctic ozone have provided evidence that the early phases of ozone recovery have been occurring. A new paper published in Science presents the first signs ozone healing may be occurring as well. The data shows an overall increase in the thickness and abundance of the Antarctic ozone layer in the last 15 years.

The Antarctic ozone hole fluctuates in size over the course of a year. It is largest during the spring, which occurs from September to November in the southern hemisphere. Historically, the majority of each year’s ozone hole growth occurs in late August and early September, building to a peak in October.

Austin Haughwout thought he'd be facing a legal showdown with the Federal Aviation Administration over his armed drone, but now he's got bigger legal problems.

The 19-year-old Connecticut man was arrested yesterday on child pornography charges. He also faces charges of enticing a minor and attempted sexual assault. The arrest warrant is sealed, but local police outlined the allegations against Haughwout to The Hartford Courant.

The arrest is a result of a "lengthy investigation" that has its origins in a violent incident from July 2015. That month, Haughwout went to the police department to turn himself in due to charges "stemming from a confrontation with officers at the town's library," the Courant reported. While he was being arrested, Haughwout engaged in "assaultive behavior with the officers that were taking him into custody."

We already knew that Hillary Clinton's e-mail and mobile device issues were likely a pain for State Department employees—and even some foreign governments. But new testimony recorded on Tuesday by one of Clinton's top aides illuminates the extent of those headaches.

Huma Abedin is the vice-chair of Clinton's presidential campaign and the former deputy chief of staff and senior advisor to Clinton during her stint as Secretary of State. She was deposed on June 28 by an attorney representing the conservative action group Judicial Watch as part of discovery for a lawsuit being brought against Clinton. Judicial Watch published the transcript of that deposition yesterday, and Abedin revealed what she knew about Clinton's use of the mail server and how she was "frustrated" with the technical glitches caused by Clinton's mobile device and e-mail travails. 

Both Clinton and Abedin had accounts on the clintonemail.com server, which was originally set up at the Clinton residence by staffers of former president Bill Clinton prior to the family's arrival at the State Department. (The server would later be managed by Platte River Networks, a managed IT services firm, with security provided by Datto.) Clinton had been using a BlackBerry mail account through AT&T during the 2008 presidential campaign, and she had been having "technical issues" with the account, according to Abedin. Clinton switched to the private server when she got a new device, and Abedin was given an account on the server after she lost access to her Senate e-mail account. Abedin said she used it primarily for personal business in addition to a personal Yahoo e-mail account (where she would later forward press clippings received from a State Department clipping service, she said).

Verizon Wireless says it has a big announcement coming next week, and rumors suggest the mobile carrier will start offering rollover data and a "safety mode" that lets customers use slower data without paying overage fees once their monthly high-speed data allotments run out.

The new plans are described in the above image, which was posted by a Reddit user and allegedly comes from a Verizon test site that occasionally leaks new offerings before they hit the main Verizon website. Verizon didn't confirm or deny the new offerings, but the company vaguely told news sites that "We're going to have some fireworks next week—stay tuned."

The "Carryover Data" referenced in the Verizon leak would let customers roll unused data over to their next monthly allotment, similar to rollover plans introduced about 18 months ago by T-Mobile USA and AT&T.

After launching 12 years ago and achieving its primary mission of reaching an orbit around Comet 67P/Churyumov–Gerasimenko, the aging Rosetta spacecraft will now die. On September 30, the European Space Agency says it will command Rosetta to crash into the comet it has been following since 2014.

Now at a distance of more than 850km from the Sun, Rosetta's two solar arrays cannot collect enough power to guarantee the spacecraft's heaters will keep it warm enough to survive. Instead of putting Rosetta into hibernation, which engineers believe is not survivable, Rosetta will follow its Philae lander to the surface of the comet.

The journey, at least, should prove fruitful. During the final hours of descent, Rosetta will attempt to capture some very-high-resolution images of the comet while collecting other data about 67P. Scientists hope communications with the spacecraft continue right up until the very end—when it crashes into the comet.

Joshua Browder, a 19-year-old British student at Stanford University, has created a chatbot (DoNotPay.co.uk) that successfully challenged parking tickets in London and New York City.

The chat interface asks a few basic questions and then auto-generates a legal appeal for a parking ticket (it can also make a claim for compensation regarding delayed flights). Alternatively, a simple Web form is available for those who don’t want to interact with an AI.

"When I started the website, it was because I got a few parking tickets myself," Joshua Browder told Ars by phone. "Local governments aren’t issuing these tickets when people are doing something wrong—they’re doing it to raise revenue."
