Scientists at a Nevada earthquake lab Wednesday tested new bridge designs with connectors they say are innovative and created to better withstand violent temblors and speed reconstruction efforts after major quake damage.

University of Nevada, Reno engineers performed the experiments on a giant “shake table” to simulate violent motions of an earthquake to rattle a 100-ton (91-metric ton), 70 foot (21-meter) bridge model to determine how well it would hold up.

The tests, conducted a day after a big quake struck Mexico, shook large concrete columns and beams back and forth for about 30 seconds at a time, displacing some nearly a foot before returning largely to their original spot.

Graduate students measured and marked indications of tiny fractures but no major structural damage was observed in the initial review of the experiments.

“The bridge has done better than we expected,” said Saiid Saiidi, a professor of civil and environmental engineering who served as the project leader. He’s done related research for more than 30 years.

Bridges are already designed not to collapse in earthquakes but often are unsafe for travel after big quakes. He said the designs that were tested employed special types of connectors to link prefabricated bridge parts, including ultra-high performance concrete.

“Earthquakes by themselves don’t kill people, it’s the structures,” Saiidi said.

The elements have been tested on their own but never before combined in a bridge model subjected to realistic earthquake motions, like the 1994 Northridge, California quake. Wednesday’s test inside the University of Nevada’s Earthquake Engineering Laboratory simulated activity of a quake as large as magnitude 7.5.

Some design work by the engineers has been incorporated into a highway off-ramp under construction in Seattle. It’s the first bridge in the world that uses flexible columns and reinforcement bars made out of a metal alloy with titanium that bends and then springs back into shape when quakes hit.

Among other things, the innovative connectors allow for prefabricated concrete and other materials to be attached to an existing bridge foundation so as to speed repair and reconstruction.

Part of the research centers on a so-called “pipe pin” connection developed by the California Department of Transportation’s bridge designers for use in connecting certain beam interfaces in bridge construction.

The pin consists of a steel pipe that is anchored in the column and extended into a steel can embedded in the beam. A gap between the steel pipe and the can enables the extended segment to freely rotate inside the steel can and prevents bending of the protruded segment inside the can.

The University of Nevada’s Earthquake Engineering Lab is the largest of its kind in the United States.

The latest project is funded by the California Department of Transportation, which currently is developing plans for 10 pilot projects based on the developing bridge connector technology.

“This study today is going to allow them to make observations of those designs,” Saiidi said.

Removing extremist content from the internet within a few hours of it appearing poses “an enormous technological and scientific challenge,” Google’s general counsel will say later Wednesday to European leaders who want it taken down quicker.

Kent Walker, general counsel for Alphabet’s Google, will speak on behalf of technology companies Facebook, Microsoft, Twitter and YouTube at an event on the sidelines of the annual gathering of world leaders at the United Nations.

The leaders of France, Britain and Italy want to push social media companies to remove “terrorist content” from the internet within one to two hours of it appearing because they say that is the period when most material is spread.

“We are making significant progress, but removing all of this content within a few hours — or, indeed, stopping it from appearing on the internet in the first place — poses an enormous technological and scientific challenge,” Walker will say in a speech on behalf of the Global Internet Forum to Counter Terrorism, a working group formed by the four companies to combine their efforts to remove extremist content.

Tech firms have come under increasing pressure from governments in the United States and Europe to do more to keep extremist content off their platforms after a spate of militant attacks, and the European Union is mulling legislation on the issue.

“There is no silver bullet when it comes to finding and removing this content, but we’re getting much better,” Walker will say.

“Of course, finding problematic material in the first place often requires not just thousands of human hours but, more fundamentally, continuing advances in engineering and computer science research. The haystacks are unimaginably large and the needles are both very small and constantly changing.”

Walker will say the companies need human reviewers to help distinguish legitimate material such as news coverage from the problematic material and train machine-learning tools against “ever-changing examples.”

The companies last year decided to set up a joint database to share unique digital fingerprints they automatically assign to videos or photos of extremist content, known as “hashes,” to help each other detect and remove similar content.

Facebook used a hash that contained a link to bomb-making instructions to find and remove almost 100 copies of that content.

Twitter said Tuesday that it had removed 299,649 accounts in the first half of this year for the “promotion of terrorism,” while Facebook has ramped up its use of artificial intelligence to map out pages and posts with terrorist material.

A chief gripe with Apple Watch is that it requires you to keep an iPhone with you for most tasks. The inclusion of GPS last year helped on runs and bike rides, but you’re still missing calls and messages without the phone nearby.

A new model with its own cellular-network connection is Apple’s next step toward an untethered world. Now you can make and receive calls and messages on the watch while leaving your phone at home.

But the watch still needs regular contact with an iPhone, and for most tasks, the phone needs to be on and connected, even if it’s nowhere nearby. So, you can’t get away with ditching the iPhone altogether. (Android users have their own wristwear options, including Samsung Gear and Android Wear watches, some of which can already manage their own network connections.)

The new Apple Watch Series 3, distinguished by a red crown, comes out Friday starting at about $400. You can forgo cellular, and the red crown, for $70 less. Or get a first-generation model, without GPS, for about $250.

Where it helps

You might not want to bring your phone on a short jog; the watch can still keep you in touch. Or you can leave the phone home while walking the dog or performing a quick errand.

You need a data add-on from the same wireless provider as your phone. It typically costs $5 or $10 a month and uses the phone’s data allotment.

While the watch technically has its own phone number, the major carriers have worked out number syncing. Calls to your phone will go to the watch, and calls from the watch will appear on caller ID with your regular number. Same goes for texts and iMessage chats.

Calls use the watch’s speaker and microphone, or wireless earphones. Colleagues say call quality was fine. It came in handy for sneaking in runs during conference calls (though if you’re my boss, just kidding! Now, about that raise …).

Phone calls and iMessage chats work on the watch even if your phone is off, as do turn-by-turn maps and queries to the Siri voice assistant. For texts, the phone needs to be on — somewhere. With the phone on, you can perform a variety of other tasks, including checking weather apps, Yelp recommendations and notifications that go to the phone.

Coming soon: the ability to stream Apple Music, even with the phone off. Unfortunately, this doesn’t apply to rival music services or Apple’s podcast app.

Limitations

Because the watch screen is small, many apps offer only a sliver of information and refer you back to the phone to view more. That was little more than an annoyance when the phone was in the same room. If you’ve left the phone behind, though, you’ll be left hanging.

You can also run into trouble while roaming, particularly internationally. For one thing, engineers weren’t able to squeeze in support for cellular frequencies around the world. And outside the U.S., only a handful of carriers are supporting the cellular watch. In any case, don’t forget to switch to airplane mode on flights.

Cellular data also drains the battery quicker. Apple’s promised 18 hours of battery life includes about four hours of such use. An hour of phone calls over LTE will drain the battery completely.

I got dropped from two conference calls because the battery was low to begin with. Plan ahead. A spare watch charger at your desk helps for those days you’re dumb enough to leave your phone on the kitchen counter.

Embracing the tether

It can be handy to untether the watch at times, but it’s not always necessary. Even when tied to the phone, Series 3 offers improvement such as tracking elevation, so you get credit for climbing stairs or jogging up a hill. And you can now hear Siri responses on the watch speaker, something enabled by the new version’s faster processor.

Software update

For owners of past models, a software update out this week, watchOS 4, will bring easier access to music playback controls when exercising — just swipe left. There are more prompts when reaching or nearing daily goals, and options for multiple sports in a single workout.

A new heart rate app now shows heart rate at rest and averages when walking or recovering from exercise. These can help you gauge your overall fitness.

And if your heart rate is high without any signs of exercise, you’ll get an alert. You enable this when you first open the heart rate app. It can signal health problems, though Apple is stopping short of telling you to see a doctor or visit the emergency room, as the watch isn’t marketed — or certified — as a medical device.

Amazon is attempting to develop glasses that pair with Alexa and would allow users to access the voice-activated assistant outside the home, according to a newspaper report.

The Financial Times, citing anonymous sources, says the glasses could be released before the end of the year.

Amazon.com Inc., based in Seattle, did not immediately respond to a request for comment Wednesday.

Wearable technology, glasses specifically, is already in limited use. Snapchat sells $130 glasses that take a short video and post it on the social media app. And Alphabet Inc. sells Google Glass to employers, so that doctors or factory workers can search information or talk to co-workers hands free.

A cardiac arrest happens when the heart stops beating regularly, due to mixed up electrical signals. According to the American Heart Association, when cardiac arrest occurs, every minute that passes before help arrives lowers a person’s chance of surviving by seven to 10 percent.

A mobile phone app is the latest tool for campaigners seeking to end child marriage in India’s Bihar state, where nearly two-thirds of girls in some of its rural areas are married before the legal age of 18.

The app, Bandhan Tod, was developed by Gender Alliance — a collective of more than 270 charities in Bihar focused on gender rights — and launched this week by Deputy Chief Minister Sushil Kumar Modi. It is backed by the U.N. Population Fund.

India ranks among countries with the highest rates of child marriage in the world, accounting for a third of the global total of more than 700 million women, according to UNICEF, the United Nations children’s agency.

Bandhan Tod — meaning “break the binds” — includes classes on child marriage and dowries and their ill effects. It also has an SOS button that notifies the team when activated.

“The app is a big part of our efforts to end child marriage in the state,” said Prashanti Tiwary, head of Gender Alliance.

“Education is good, but when a young girl wants help because she is being forced to marry before the legal age, the app can be her way out,” she told the Thomson Reuters Foundation.

Despite a law banning girls from marrying before they turn 18, the practice is deeply rooted in tradition and widely accepted in Indian society. It is rarely reported as a crime and officials are often reluctant to prosecute offenders.

While boys also marry before the legal age of 21, girls are disproportionately affected.

Risks of abuse, death rise

Early marriage makes it more likely that girls will drop out of school, and campaigners say it also increases risks of sexual violence, domestic abuse and death in childbirth.

Legal efforts have failed to break the stranglehold of tradition and culture that continues to support child marriage, charity ActionAid India said in a report this year.

When the SOS on Bandhan Tod is activated, the nearest small NGO will attempt to resolve the issue. If the family resists, then the police will be notified, said Tiwary.

A similar app in West Bengal state to report child marriage and trafficking of women and children has helped prevent several such instances, according to Child in Need Institute, which launched the app in 2015.

Other efforts include a cash incentive, where the state transfers a sum of money to the girl’s bank account if she remains in school and unwed at age 18.

Suppliers of wedding tents in Rajasthan state have stopped dozens of child marriages by alerting officials.

“It will take a change in mindset and behavior to end child marriage,” said Tiwary, who is lobbying the government to raise the marriage age for women to 21, so they have the same opportunities as men.

“But technology provides a practical and accessible way to help prevent it on the ground,” she said.

Twitter said that its internal controls were allowing it to weed out accounts being used for “promotion of terrorism” earlier rather than responding to government requests to close them down.

U.S. and European governments have been pressuring social media companies including Twitter, Facebook and Alphabet’s Google to fight harder against online radicalization, particularly by violent Islamist groups.

Twitter said it had removed 299,649 accounts in the first half of this year for the “promotion of terrorism,” a 20 percent decline from the previous six months. Three-quarters of those accounts were suspended before posting their first tweet.

Less than 1 percent of account suspensions were due to government requests, the company said, while 95 percent were thanks to Twitter’s internal efforts to combat extremist content with “proprietary tools,” up from 74 percent in the last transparency report.

Twitter defines “promotion of terrorism” as actively inciting or promoting violence “associated with internationally recognized terrorist organizations.”

The vast majority of notices from governments concerned “abusive behavior,” which includes violent threats, harassment, hateful conduct and impersonation.

The difference between Apple’s new iPhone models is a bit like flying first class compared with coach. We envy first class, but coach gets us there without breaking the budget.

The iPhone 8 will do just fine for $300 less than the glitzy iPhone X , even though it won’t make your friends and colleagues jealous. It’s also available much sooner – this Friday – starting at almost $700. The X (read as the numeral 10) won’t be out until November.

Still, the iPhone 8 remains a fairly straightforward update of the iPhone 7 , which itself was a fairly straightforward update of the iPhone 6S. Then again, no one expects much different from a coach seat.

What you’re not getting

It’s hard to talk about the iPhone 8 without comparing it to my 15 minutes with the iPhone X last Tuesday.

The X wowed with a fancy new display that flows to the edges of the phone. The phone is compact, yet features a screen slightly larger than the one on the supersized iPhone 8 Plus. The X also features facial recognition that lets you unlock the phone with a glance; you can also create animated emojis that match your facial expressions.

The 8 has none of that, although it does share other new goodies the X is getting, including wireless charging. The 8 and the X both have faster processors and sensors to enhance graphics in augmented reality, a blending of the virtual and physical worlds, though older iPhones will also run AR apps with a software update Tuesday.

Wireless charging

Apple is embraces wireless-charging technology that Android phones have had for years. It’s a rare case in which Apple isn’t going its own way; instead, it’s adopting an existing standard called Qi (pronounced chee). That means the iPhone gets all the technical advancements from the consortium behind Qi _ and can take immediate advantage of a slew of public wireless-charging stations.

It worked perfectly for me while waiting for a connecting flight in Los Angeles – no need to rummage through my backpack for a charging cord.

Apple says the wireless system should charge as quickly as the wall adapter included with iPhones. But I found wireless slower in testing, using a Belkin charger with the same power output as the iPhone charger.

Wireless charging is largely about convenience; it’s terrific if you can just drop your phone on a charging pad overnight or during the day at your desk. Apple says it will boost wireless-charging power by 50 percent in coming months, which will speed things up further. But those in a rush should consider a wall charger that comes with the iPad, which will still be even faster.

In a way, wireless charging makes up for Apple’s earlier decision to ditch the headphone jack in the iPhone 7, which made people share the Lightning port with both charging cords and wired headphones. You can now charge and use wired headphones at the same time.

Display

Colors on the 8’s screen adapt to lighting in the room. It’s noticeable in my apartment at night, as artificial lighting tends to be warmer and more yellowish. The screen adapts by making whites more like beige and yellow even yellower. It’s softer on the eyes and mimics how light glows on white paper, though it can make images appear less natural. You can turn this feature off.

Resolution isn’t as sharp as what the X and many rival Android phones offer. The Plus offers enough pixels for high-definition video at the highest quality, 1080p, while the regular model is comparable to the lesser 720p.

Camera

New color filters produce truer and richer colors without looking fake, while a new flash technique tries to light the foreground and background more evenly. You have to know to look, as the iPhone 7 already had a great camera. Differences in test shots taken while sightseeing in Poland were subtle, but noticeable – more so on the iPhone 8 screen than on last year’s Mac.

The iPhone 8 also offers additional video options, including recording of ultra-high definition, or 4K, at 60 frames per second, twice the previous rate. (The phone’s display, though, isn’t sharp enough for 4K.)

A second lens in the 7 Plus and 8 Plus models lets the camera gauge depth and blur backgrounds in portrait shots, something once limited to full-featured SLR cameras. Samsung adopted that feature in this year’s Note 8 .

Coming to the 8 Plus are filters to mimic studio and other lighting conditions. My favorite, stage light, highlights the subject’s face and darkens the background. Some of these filters make images look fake – Apple has slapped a “beta” test tag to signal it’s not flawless. You can try them out and undo any changes you don’t like.

Design

To make wireless charging work, the 8 features a glass back, something last seen in the iPhone 4S in 2011. Aesthetic considerations aside, this gives you another sheet of glass to break.

Apple says custom glass from Corning makes the phone stronger. Even so, consider a service plan and get a case. Wireless charging works with most cases, as long as there’s no metal or magnets. I found the phone charged just as fast with the case on.

About the price tag

The iPhone 8 is about $50 more than what the iPhone 7 cost at launch. Samsung has similarly increased the prices of its flagship Galaxy phones, and the S8 still outsold last year’s S7. Consumers seem willing to pay.

You do get double the storage – 64 gigabytes – at that price, a value considering that iPhone storage boosts typically cost $100. You’ll need that extra storage for video, apps and fancy features such as AR and animated photos.

Nonetheless, I would have preferred the option of a cheaper, lower-storage version. For that, you need an older model , such as the $549 iPhone 7 and the $449 6S. There’s also the smaller iPhone SE for $349.

Alphabet unit Google has offered to display rival comparison shopping sites via an auction as part of an EU compliance order following a landmark fine for favoring its own service, four people familiar with

the matter said on Monday.

The proposal, submitted to the European Commission on August 29 following a record 2.4-billion-euro ($2.87 billion) penalty, would allow competitors to bid for any spot in its shopping section known as Product Listing Ads, the people said.

Three years ago, the world’s most popular internet search engine made a similar offer in an attempt to settle a long-running investigation by the European Commission and stave off a fine. The offer was ultimately rejected following negative feedback from rivals and discord within the EU executive.

Under this earlier proposal, Google had reserved the first two places for its own ads. The new offer would also see Google set a floor price with its own bids minus operating costs. The company has sought feedback from competitors.

The offer does not address the issues set out by EU competition regulators, the people said. The Commission had ordered Google to treat rivals and its own service equally.

“This is worse than the commitments,” one of the people said, declining to be named because of the sensitivity of the matter.

The Commission was not immediately available for comment.

Google did not respond to a request for comment. Google has until September 28 to stop its anti-competitive practices or its parent company Alphabet could be fined up to 5 percent of its average daily worldwide turnover.
