NASA Is Investigating a Bizarre Explosion on the Sun

Posted by in category: space

The explosion contained elements of three different types of solar eruptions: Bubble-like coronal mass ejections, beam-like jets, and partial eruptions that collapse onto themselves. Those eruptions all happen independently of one another, making this hybrid the first of its kind to ever be spotted, according to CNET. NASA is referring to the explosion as a sort of “solar Rosetta Stone,” comparing it to the ancient slab that helped researchers decode Egyptian hieroglyphs, because picking apart the three different eruptions could help researchers finally understand the root causes for each and how they differ.

The 2016 explosion was too big to be a jet but too narrow to be a coronal mass ejection, according to a NASA press release. And when it finished, a partial eruption emerged from the same place just to bubble up and fall back onto itself. Seeing all three forms of eruption emerge in the same place and within the same hour suggested to NASA that all three are caused by the same mechanisms, according to the research, which was presented at Monday’s American Astronomical Society meeting and has been accepted for publication in Astrophysical Journal Letters.

“This event is a missing link where we can see all of these aspects of different types of eruptions in one neat little package,” NASA solar scientist and lead study author Emily Mason said in the release. “It drives home the point that these eruptions are caused by the same mechanism, just at different scales.”

Relativity has a bold plan to take on SpaceX, and investors are buying it

Posted by in category: space

“We’re trying to ice skate to where the puck is going,” Ellis said, adding that Relativity wants to be similarly disruptive to SpaceX, but in its own way. “What we keep hearing from customers is that they don’t want just a single launch company that is, frankly, the only quickly moving, disruptive provider.”

Powered by seven main engines, the Terran R vehicle will initially launch from Cape Canaveral Space Force Station in Florida. Relativity has set a goal to launch in 2024, and Ellis said the company has signed a binding contract for multiple launches with an “anchor customer” he declined to name. Relativity has not publicly released a price for a launch.

MIT is Building a Dynamic, Acrobatic Humanoid Robot

Posted by in category: robotics/AI

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.

Ultra-high-density hard drives made with graphene store ten times more data

Posted by in categories: computing, materials

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.

The military is funding a “living pharmacy” scientists can stick inside you

Posted by in categories: biotech/medical, military

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.

Unexpected discovery opens a new way to regulate blood pressure

Posted by in category: biotech/medical

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.

Activating Genes With a Smartwatch to Control Insulin Production

Posted by in categories: biotech/medical, engineering

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.”
