This small-scale humanoid is designed to do parkour over challenging terrains.

For a long time, having a bipedal robot that could walk on a flat surface without falling over (and that could also maybe occasionally climb stairs or something) was a really big deal. But we’re more or less past that now. Thanks to the talented folks at companies like Agility Robotics and Boston Dynamics, we now expect bipedal robots to meet or exceed actual human performance for at least a small subset of dynamic tasks. The next step seems to be to find ways of pushing the limits of human performance, which it turns out means acrobatics. We know that IHMC has been developing their own child-size acrobatic humanoid named Nadia, and now it sounds like researchers from Sangbae Kim’s lab at MIT are working on a new acrobatic robot of their own.

We’ve seen a variety of legged robots from MIT’s Biomimetic Robotics Lab, including Cheetah and HERMES. Recently, they’ve been doing a bunch of work with their spunky little Mini Cheetahs (developed with funding and support from Naver Labs), which are designed for some dynamic stuff like gait exploration and some low-key four-legged acrobatics.

Graphene can be used for ultra-high density hard disk drives (HDD), with up to a tenfold jump compared to current technologies, researchers at the Cambridge Graphene Center have shown.

The study, published in Nature Communications, was carried out in collaboration with teams at the University of Exeter, India, Switzerland, Singapore, and the US.

HDDs first appeared in the 1950s, but their use as in personal computers only took off from the mid-1980s. They have become ever smaller in size, and denser in terms of the number of stored bytes. While solid state drives are popular for mobile devices, HDDs continue to be used to store files in desktop computers, largely due to their favorable cost to produce and purchase.

If hearing the words “military,” “soldier,” and “implant” all in the same sentence conjures images of Jason Bourne, you’re not alone — and with good reason.

The military is currently working with scientists to develop new technology to implant in soldiers. But this time it has less to do with creating superhuman assassins and more to do with quelling jet lag and diarrhea.

In May, researchers from Northwestern University signed a $33 million dollar contract with the Defense Advanced Research Projects Agency (DARPA) to develop a wireless implantable device that will function as a “living pharmacy” for military personnel. It’s called a living pharmacy because everything the “patient” needs can be produced by their own body.

For all the cool regenerative tricks the human body can do, it’s kind of weird that we only have one shot at tooth enamel with no way to get it back. That may be about to change, as researchers at the University of Washington have developed a lozenge that rebuilds this precious protective coating a few microns at a time and are taking it to the trial stage. Could it really work? It’s certainly something to chew on.

Another surprising fact is that genes that control zinc levels within cells are known to be associated with cardiovascular diseases including hypertension, and hypertension is also a known side effect of zinc deficiency. This new research provides explanations for these previously known associations.

High blood pressure, or hypertension, is the leading modifiable risk factor for cardiovascular diseases and premature death worldwide. And key to treating patients with conditions ranging from chest pain to stroke is understanding the intricacies of how the cells around arteries and other blood vessels work to control blood pressure. While the importance of metals like potassium and calcium in this process are known, a new discovery about a critical and underappreciated role of another metal—zinc—offers a potential new pathway for therapies to treat hypertension.

The study results were published recently in Nature Communications.

All the body’s functions depend on arteries channeling —energy—to where it’s needed, and within these vessels direct how fast or slow the gets to each destination. As smooth muscles contract, they narrow the artery and increase the , and as the muscle relaxes, the artery expands and blood falls. If the blood pressure is too low the will not be enough to sustain a person’s body with oxygen and nutrients. If the blood pressure is too high, the blood vessels risk being damaged or even ruptured.

They need to speed these processes along.

Many modern fitness trackers and smartwatches feature integrated LEDs. The green light emitted, whether continuous or pulsed, penetrates the skin and can be used to measure the wearer’s heart rate during physical activity or while at rest.

These watches have become extremely popular. A team of ETH researchers now wants to capitalize on that popularity by using the LEDs to control genes and change the behavior of cells through the skin. The team is led by Martin Fussenegger from the Department of Biosystems Science and Engineering in Basel. He explains the challenge to this undertaking: “No naturally occurring molecular system in human cells responds to green light, so we had to build something new.”

Hundreds of websites worldwide crashed this morning following a massive internet outage – with the UK government, Amazon and Spotify among those experiencing issues.

Millions of users across the globe reported problems trying to access web pages, with Netflix, Twitch and news websites including the BBC, Guardian, CNN and the New York Times hit by the problem.

Passengers desperately trying to fill out locator forms on UK.Gov to enter the UK from Portugal and abroad were also affected by the outage.

The U.S. Department of Treasury and NASA did not immediately respond to CNBC’s requests for comment.

Launched in 1998, the ISS serves as the largest hub for scientific research and collaboration in orbit. The U.S., Russia, Canada and Japan alongside a dozen countries participating in the European Space Agency work in support of the ISS.
