Harvard University researchers have made a breakthrough in battery tech: a long-lasting solid-state lithium battery.
“A lithium-metal battery is considered the holy grail for battery chemistry,” researcher Xin Li told the Harvard Gazette.
Strong, cheaper, faster: Most of today’s electric vehicles (EVs) are powered by lithium-ion batteries, the same type of battery you’ll find in your laptop or smartphone.
Soon, the majority of portable PCs won’t need to be equipped with an ugly barrel jack and a proprietary power brick to charge. The USB Implementers Forum (USB-IF) has just announced that it’s more than doubling the amount of power you can send over a USB-C cable to 240 watts, which means you’ll eventually be able to plug in the same kind of multipurpose USB-C cable you currently use on lightweight laptops, tablets, and phones to charge all but the beefiest gaming laptops.
Extended Power Range.

As the world is running out of lithium, planet-friendlier batteries are waiting to hit the market. We are using up lithium, the essential metal in rechargeable batteries. Some experts estimate that there won’t be any lithium left by 2035, and some say that it may already disappear within four years. Who should lose sleep over this? Anyone with a smartphone, a laptop or an electric car. Without lithium, they would have to be plugged in at all times.
But it’s not just about comfort. Lithium also plays an important role in storing wind and solar energy, an increasingly important sector. Therefore, the world is in the midst of a battery revolution.
An iPhone app that estimates biological aging discovered that life expectancy has the capacity to be almost double the current norm.
GEYLANG, Singapore — Have you made any plans for the 22nd century yet? A new study finds you might want to think about it because it’s possible for humans to live to see their 150th birthday!
Scientists in Singapore have developed an iPhone app that accurately estimates biological aging. It discovered that life expectancy has the capacity to be almost double the current norm. The findings are based on blood samples from hundreds of thousands of people in the United States and United Kingdom.
The instrument, called DOSI, uses artificial intelligence to work out body resilience, the ability to recover from injury or disease. DOSI, which stands for dynamic organism state indicator, takes into account age, illnesses, and lifestyles to make its estimates.
It may not look nice, but maybe it can help prevent accidents. 😃
It’s generally good to watch where you’re going while out walking around, but if you’re someone who just can’t resist a glance at your phone – or a full scrolling session – then this industrial design student’s third eye is for you.
Created as part of his Innovation Design Engineering degree at London’s Royal College of Art and Imperial College, student Minwook Paeng came up with the impressive piece of tech to help out all the ‘phono-sapiens’ out there.
With so much of our lives now wrapped up in our phones, Paeng’s ‘third eye’ offers a solution to issues that can present themselves as we walk around with our heads down, taking in everything on the screen.
Tune in to find out about how we’re furthering our mission to organize the world’s information and make it universally accessible and useful.

These clever semiconductors make our internet-connected world go round. In addition to iPhones and PlayStations, they underpin key national infrastructure and sophisticated weaponry.
But recently there haven’t been enough of them to meet demand.
The reasons for the ongoing global chip shortage, which is set to last into 2022 and possibly 2023, are complex and multifaceted. However, nations are planning to pump billions of dollars into semiconductors over the coming years as part of an effort to sure up supply chains and become more self-reliant, with money going toward new chip plants, as well as research and development.
Marilyn Monroe famously sang that diamonds are a girl’s best friend, but they are also very popular with quantum scientists—with two new research breakthroughs poised to accelerate the development of synthetic diamond-based quantum technology, improve scalability, and dramatically reduce manufacturing costs.
While silicon is traditionally used for computer and mobile phone hardware, diamond has unique properties that make it particularly useful as a base for emerging quantum technologies such as quantum supercomputers, secure communications and sensors.
However there are two key problems; cost, and difficulty in fabricating the single crystal diamond layer, which is smaller than one millionth of a meter.
Did you know your Pixel had this? Did you know any phone had this? Google now wants you to know about it.
ETH Computer scientists have developed a new AI solution that enables touchscreens to sense with eight times higher resolution than current devices. Thanks to AI, their solution can infer much more precisely where fingers touch the screen.
Quickly typing a message on a smartphone sometimes results in hitting the wrong letters on the small keyboard or on other input buttons in an app. The touch sensors that detect finger input on the touch screen have not changed much since they were first released in mobile phones in the mid-2000s.
In contrast, the screens of smartphones and tablets are now providing unprecedented visual quality, which is even more evident with each new generation of devices: higher color fidelity, higher resolution, crisper contrast. A latest-generation iPhone, for example, has a display resolution of 2532×1170 pixels. But the touch sensor it integrates can only detect input with a resolution of around 32×15 pixels—that’s almost 80 times lower than the display resolution: “And here we are, wondering why we make so many typing errors on the small keyboard? We think that we should be able to select objects with pixel accuracy through touch, but that’s certainly not the case,” says Christian Holz, ETH computer science professor from the Sensing, Interaction & Perception Lab (SIPLAB) in an interview in the ETH Computer Science Department’s “Spotlights” series.
