Plate tectonics may have gotten a pretty early start in Earth’s history. Most estimates put the onset of when the large plates that make up the planet’s outer crust began shifting at around 3 billion years ago. But a new study in the Sept. 22 Science that analyzes titanium in continental rocks asserts that plate tectonics began 500 million years earlier.

Using data from the first-ever gravitational waves detected last year, along with a theoretical analysis, physicists have shown that gravitational waves may oscillate between two different forms called "g" and "f"-type gravitational waves. The physicists explain that this phenomenon is analogous to the way that neutrinos oscillate between three distinct flavors—electron, muon, and tau. The oscillating gravitational waves arise in a modified theory of gravity called bimetric gravity, or "bigravity," and the physicists show that the oscillations may be detectable in future experiments.

As kids, our parents drill it into our brains. As adults, we see it posted near bathroom mirrors everywhere. We’re constantly reminded of the importance of washing our hands, yet sometimes we still ask ourselves if it’s really such a big deal. One high school teacher in North Carolina has come up with a brilliant, albeit slightly nauseating experiment that shows the potency of germs in full view, and it just might save a few sinuses this flu season.

hile some still try to deny that our climate is changing, others have to deal with it already. The residents of Los Angeles are among them, and now they’re looking for some ‘outside the box’ ideas to fight the unbearable heat. To combat temperatures that reach 130 -140 degrees on the road’s surface, the city of Los Angeles has started a pilot project to test out the “cool pavement.” 15 streets were covered with this asphalt-based paint-like substance to cool down the streets by about 11-13 degrees Fahrenheit and therefore cools down the buildings around them.

Polaroid instant-photo cameras have been around for years, but as the technology improves, so does the capabilities of it. And finally, the know-how is here to build an instant-GIF camera! In this DIY project, a rather brilliant engineer named Abhishek has tackled yet another whacky idea of his to update the classic Polaroid OneStep camera with the 21st-century tech. Hence, the “Instagif NextStep” was made, capable of capturing a short video of the moment and loop it like a proper GIF.

Not all iPhones and iPads will be able to run iOS 11: anyone with an iPhone 5 or 5C, or iPad 4 or older is out of luck. But the majority of devices bought in the last few years will be able to download the update for free via the Settings app or through iTunes on a computer. If you have any older apps installed that haven’t been updated in a while, be warned that they may not work after installing iOS 11, as it drops support for 32-bit apps. Most will be fine, but you can find out if any of the apps you have installed on iOS 10 won’t work before updating.

The biggest and the smallest of the world's fish, birds, mammals, amphibians and reptiles are most at risk of dying out.Size matters when it comes to extinction risk, with vertebrates in the so-called "Goldilocks zone" - not too big and not too small - winning out, say scientists. Action is needed to protect animals at both ends of the scale, they say.

Microsoft has confirmed that some users of its email service Outlook are unable to send email or access their accounts. Hundreds from around Europe have commented on the website Downdetector that they have been affected by the problem - many since Monday morning. One common issue seems to be that sent emails remain in the drafts folder and are not being delivered to recipients.

Policy debates on climate change and sustainable development routinely cite the massive numbers needed to achieve the United Nations Sustainable Development Goals (SDGs): an additional $1 trillion annually in clean energy investments to limit global warming to below 2 degrees and between $5-7 trillion a year to achieve the SDGs. These numbers are overwhelming – but there is good news. When put in context with broader economic activity, these are far more manageable than they first appear.

A new study has revealed that at least one dinosaur species laid eggs that were a striking blue-green colour - and that suggests the creatures were even more like birds than we previously thought.

Forecasters reported Monday that Maria had grown into a Category 3 hurricane moving west-northwest with maximum sustained winds of about 120 mph.

While the scientists are warning that the humanity is rapidly approaching the point, after which the drastic climate change is pretty much irreversible, others try to prove them wrong and destroy even those minor improvements we managed to reach. While people and nature are already dealing with the environmental consequences of irresponsible humans’ behavior and are forced to live in the circumstances of terrible pollution, the shortage of drinking water and the lack of food, others promote the production that damages the environment and fosters climate change, continue denying the damaging effects and making money on something that makes the bright future of further generations quite questionable.

C.F. Møller‘s International School Nordhavn, the biggest school in Copenhagen, Denmark, has made a leap into the 21st century by transforming more than 6,000 square meters of its facade with over 12,000 solar sea-green panels. None of that sounds like a small feat, but surprisingly, making clear panels in one specific color was one of the biggest challenges that took researchers around 12 years to figure out.

It is too soon to determine whether central banks should issue their own cryptocurrencies, the Bank for International Settlements said on Sunday, as the risks could not yet be fully assessed and the technology underpinning them is still unproven.Central banks already use electronic money - only a very small proportion of their assets are now backed by gold - but this is exchanged in a centralized fashion, across accounts at the central bank.

What’s the single most important thing driving the world’s economies? It isn’t multinational corporations, infrastructure or technology, it’s the education and the skills we all have as individuals. It may be known by the anonymous-sounding term ‘human capital’, but it is about teaching, learning and training; it’s about investing in people. And how we do it is a key factor in ensuring economic growth in the future.

It's tough being different - especially when you're an 8-year-old who absolutely loves bugs and brings them to school as friends.

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole behind. For a long time, scientists have suspected that the liberated electron and the positively charged hole form a new kind of quasiparticle—known as 'core-exciton'. But so far, there has not yet been a real proof of its existence. Scientists have a wide range of tools to track excitons in semiconductors in real-time. Those are generated by ordinary light, and can be employed in various applications in optoelectronics and microelectronics. On the contrary, core-excitons are extremely short-lived, and up to now, no technique was available to track their motion and deduce their properties.

As a CEO at a tech company, I've learned to hone complementary skills to propel our business forward.A few weeks ago I was hosting an informal chat with some interns at our San Francisco office. I try to do this at our major offices throughout the summer because it's important that every person working on our business (even if it's just for a few weeks) understands how their contribution connects to our mission.

Dr. Travis Bradberry shares the skills you should learn that will pay dividends forever.The further along you are in your career, the easier it is to fall back on the mistaken assumption that you’ve made it and have all the skills you need to succeed.
