A team of researchers from the University of Arizona have penned a new study detailing the creation of a microscope capable of capturing the speed of a electron.

The new research has been published in the Science Advances journal and details the creation of an attosecond electron microscope, or a microscope that instead of using typical camera sensors that capture visible light use direct beams of electrons that pass through whatever the target object is. Researchers transmit these electrons in pulses and the faster a pulse moves through an object, the greater the resolution. Additionally, camera sensors capture the interaction between the electrons and the target sample.

All of the aforementioned data is used to create the end result images. However, ultrafast electron microscopes work by releasing a train of electrons in at a few attoseconds, which is one quintillionth of a second. It's best to think of each of these electron pulses as frames per second (FPS) in a movie or a video game. Until now, researchers were unable to capture the reaction of the electron when passing through the sample when its between each of the FPS, which restricted the total possible resolution.

The second patient of Neuralink's new brain-computer interface (BCI) chip otherwise known as a "Link" has been playing Counter-Strike 2 on his laptop using just his thoughts.

Elon Musk's exciting startup had his Neuralink implant (Link) installed last month, with the surgery taking place at the Barrow Neurological Institute, with Alex discharged the following day, and Neuralink saying "his recovery has been smooth".

With the Link installed, Alex has been improving his ability to play video games, and has started learning how to use computer-aided design (CAD) software to design 3D objects using his thoughts. Neuralink says that this "marks another significant step" towards providing a high-performance interface that will enhance the control of digital devices for people with quadriplegia to help restore their autonomy.

If you're accepted into the position of a "Data Collection Operator, Tesla Bot" then you'll need to walk a pre-determined test route daily for data collection into Optimus, while wearing a motion capture suit and a VR headset, performing designated movements and actions, based on the project requirements.

You'll need to start/stop recording devices and perform minor equipment and software debugging, while providing feedback on the performance of the equipment, and then analyzing and reporting on that data during your shift. You'll need to upload data collected and write daily reports detailing your observations and issues, while ensuring equipment is in proper and safe working condition and safely transported to various collection sites.

The International Space Station (ISS) is a floating laboratory that is manned by astronauts conducting vital science in microgravity.

At an altitude of approximately 250 miles and a moving speed of 17,500 mph, the ISS completes one orbit of Earth approximately every 93 minutes, which is 15.5 orbits every day. Given its position the ISS is certainly disconnected from many of the pleasures found on Earth's surface, and one of these pleasures is the joyous experience of eating fresh fruit. Up there fresh fruit is considered a delicacy.

However, a Russian cargo spacecraft arrived at the ISS over the weekend and delivered close to three tons of supplies, and included in those supplies was a small amount of fresh fruit. The moment was so monumental that it was captured on video and posted to ISS astronaut Matthew Dominick's X account. The short video showed a piece of an orange being pushed toward Dominick in microgravity, resulting in a floating piece of orange that was consumed mid-air by the astronaut.

In April, Earth was hit by a huge solar storm that caused auroras to light up the night sky as far south as Arizona.

Auroras are caused by solar particles interacting with Earth's magnetic field in the upper atmosphere, and now NASA has revealed some more spectacular than incredible colors that occurred during the event. According to the NASA Sun & Space X account, for a brief period of time, a "two-way highway" formed between the Sun and Earth. This rare anomaly was caused by the Sun's coronal mass ejection (CME), a blast of solar particles traveling slower than waves called Alfvén waves.

Typically, the opposite occurs, but during the April 24 event, NASA's Magnetospheric Multiscale spacecraft recorded the CME traveling slower than the Alfvén waves moving through solar plasma. Bow shocks are shockwaves created when the solar wind blows on a planet's magnetic field, and during the April 24 event, the bow shock temporarily disappeared, causing charged particles to spew back at the Sun for approximately two hours.

A team of researchers have used NASA and the European Space Agency's James Webb Space Telescope, the world's most powerful space telescope, to attempt to uncover the mystery surrounding how fast the universe is expanding.

Scientists have been battling to solve what is widely referred to as the "Hubble tension," which is the conflicting answer between the two methods that can be used to measure the expansion rate of the universe. Observations of distant supernovae suggest a lower rate of expansion, while measurements of cosmic objects closer indicate a higher rate of expansion.

The lack of a unified result causes the "Hubble tension," which refers to the astronomer Edwin Hubble, who discovered distant objects appear to be moving away from Earth faster than closer objects. For example, when measuring the Cosmic Microwave Background, the signature leftover after the Big Bang, astronomers land on a Hubble constant of 67.4 kilometers per second per megaparsec while measuring the brightness of nearby galaxies, the number jumps up to 74 kilometers per second per megaparsec.

A team of scientists at the University of California have created a brain-computer interface (BCI) that is capable of restoring a form of speech for a man suffering from amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.

The 45-year-old man named Casey Harrel suffers from ALS, which causes a loss of muscle control that can severely impact the clarity of speech. Harrel is now able to communicate his thoughts through the BCI, which converts his brain signals into words that are then "read" by the computer and spoken out loud in real time. Moreover, Harrel's BCI is designed to sound like his own voice before the disease influence how it sounded.

How does it work? The BCI was implanted into the region of the brain that is responsible for speech, and with its 256 electrodes, it is capable of analyzing brain activity sent to that region of the brain and then converting it into readable data for the computer to interpret. More specifically, the BCI converts brain activity into what is called a "phoneme" or a "syllable or the unit of speech."

It's always nice to see researchers and technology making progress in the field of renewables, especially in areas that aren't commonly thought of as big contributors to greenhouse gases.

The construction industry isn't the first area that comes to mind when someone mentions greenhouse gases, but perhaps unsurprisingly, it contributes quite a lot. The UN Environment Programme estimates that the buildings and construction sector is by far the largest emitter of greenhouse gases, accounting for a staggering 37% of global emissions.

To reduce global emissions, researchers from the University of Tokyo penned a new process of making renewable concrete bricks out of old building materials and CO2 from the air. The team first revealed the process in 2021, and since then, it has significantly improved. The renewable concrete bricks were made out of demolished school building material, which was grounded down into a fine powerder before it was then mixed with CO2 over three months.

A new study that has been published in the peer-reviewed journal Science has detailed the origins of the asteroid that caused the Chicxulub Crater, or the impact crater left behind by asteroid that ended the rein of the dinosaurs.

The Chicxulub Crater is located off the Yucatán Peninsula in Mexico and is believed to be caused by an asteroid 66 million years ago that measured six miles wide. The impact was catastrophic for life on Earth, causing a mass extinction-level event that wiped out the already declining population of dinosaurs. Researchers have penned a new study that has examined the origins of the dino-killing asteroid, tracing back its origin to the far outskirts of the solar system beyond the biggest planet in the solar system, Jupiter.

Mario Fischer-GÜdde, who researches the origin of asteroids and planets at the University of Cologne in Germany, spoke to Mashable and said the dino-killing asteroid was a "C-type asteroid," which means its composition was mostly carbon. Notably, C-type asteroids are the most common variety of asteroid, accounting for 75% of all known asteroids.

A new report from Bloomberg's Mark Gurman, a known and reliable Apple insider, has revealed the Cupertino company is planning on releasing a smart home command center sometime in 2026.

Gurman writes that Apple's new project is a tabletop robot that will have a display that's similar in size and design to a large iPad, but this display will be mounted on a "thin robotic arm". The display is capable of being rotated 360º and would be used to control smart devices around the house, FaceTime calls, and a home security monitoring tool. Additionally, the Apple command center will also come with Apple Intelligence and Siri functionality, and would be capable of distinguishing the different voices from each member of the house.

Reports indicate that Apple has thrown the company's VP of technology, Kevin Lynch, on the project, along with several hundred other Apple employees. Gurman writes the release date isn't solid and Apple is aiming for a debut sometime between 2026 and 2027 for a price tag around $1,000. Currently Apple is testing this device with a modified version of the iPadOS, with it remaining unclear if it would get its own dedicated OS or would continue using a modified version of iPadOS.

CNBC published a report on August 12 that claimed Elon Musk's SpaceX knowingly violated environmental regulations by releasing pollutants into nearby bodies of water in Texas.

The report claims the Elon Musk-led company violated wastewater regulations at its Boca Chica, Texas launch site Starbase. The report cites investigative records along with notices from the Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality (TQEC). CNBC writes that SpaceX moved quickly to rebuild its destroyed launchpad following the first test flight of Starship, causing some damage to the environment, vehicles, and the in-question launchpad.

To prevent such catastrophic damage SpaceX rebuilt the launchpad with a new deluge system capable of muffling sound, reducing heat, and energy produced by a launch. What the report claims is SpaceX skipped obtaining a permit before going ahead with their next launch. More specifically, the EPA launched an investigation into the wastewater from the new system following SpaceX's full pressure test of in July 2023. Here come the crux of the allegations.

Seismic data acquired by NASA's InSight lander, which has now retired, has revealed the presence of large liquid water reservoirs beneath the surface of Mars.

Researchers have known for some time that Mars was once home to large bodies of liquid water, which formed running river-like delta systems across various regions of the planet. Evidence of liquid water is critical to the quest of identifying any ancient microbial life on the Red Planet, as its an ingredient for life as humans know it. But what if life is still present on Mars, but humans just can't get to it as it is miles beneath the Red Planet's surface?

Data from NASA's InSight lander, which used a seismometer along with other instruments to measure Mars' geological activity, point to massive underground reservoirs of liquid water. These readings informed researchers the reservoir is so large that if it was emptied it would cover the entire planet in about a mile of ocean. Unfortunately, humans won't be able to access it for quite some time as it's located between 7 and 13 miles beneath the planet's surface in the mid-crust region.

The speed at which you can charge your phone can always be improved, and it appears we are about to showcase what the future of fast charging will look like with a new battery charging technology scheduled to be unveiled on August 14.

Realme will unveil the Realme 320W SuperSonic battery charging system, according to posts on Weibo and X, formerly Twitter. According to the teaser posts, the new charging system will be the "world's fastest charge ever," and users will now be able to "say goodbye to long waits and hello to lightning fast-power." Unfortunately, there isn't any official to go by yet, so these claims from Realme are just that, claims.

However, the brand did unveil a 240W charging system that was capable of charging a 4,600mAh battery in under 10 minutes. This incredible speed can be attributed to the combination of GaN charging technology, special USB cables, and several chipsets managing power, cooling, thermals, etc. Considering the 240W system from last year can charge a 4,600 mAh battery in under 10 minutes, we can expect the 320W to come with some pretty big improvements.

YouTube Music is moving toward adopting more social features that make interacting with the music streaming service much more communal.

The new feature will enable a user to share a pinnable playlist called a shareable personal radio, which will be updated daily with the latest songs the user has listened to and their general music tastes. The personalized ratio will be displayed on the user's profile, showcasing the top songs, playlists and videos, but it can be shared to friends via link or added to a library, and anyone with a link will be able to save this personalized radio.

Based on current reports, the new YouTube Music feature isn't available for everyone globally and is rolling out in stages. A way to check if the feature has been enabled for your region will be navigating to your profile, then "Privacy and location" under "Channel Settings," then "Enable public stats," or "Enable public personal radio." It appears these features are automatically disabled when they become available.

Perceptive, the company behind the world's first fully automated dental procedure, has provided some details on its new revolutionary robotics system.

The company explained in a press release that its new robotics system is AI-driven and recently completed the world's first fully automated dental procedure on a human using its advanced dentistry system. Notably, the new robotics system uses a combination of AI-driven 3D imaging software and robotic arms that are designed for quick but precise restorative dentistry.

According to the report, the robot is capable of performing some surgeries completely independently, and basic tasks such as crown placements can take as little as 15 minutes instead of the current procedure that takes two separate visits of one hour each. As previously mentioned, the robot uses 3D volumetric data to diagnose the target area and conceive an applicable treatment.

The last time we heard about the second human patient undergoing a Neuralink brain implant, the story was that they had to be canceled for the surgery due to the discovery of unforeseen medical issues.

However, it appears Neuralink found the right applicant as Elon Musk has revealed during an interview the company has successfully implanted its second Brain-Computer-Interface (BCI) into a human patient. Musk revealed the news on a recent 8-hour-long episode of the Lex Fridman Podcast, where the Neuralink founder sat down for an hour and a half to discuss the goal of BCIs, their potential at curing previously incurable diseases, and societal impacts of the technology being integrated with people that don't have any medical issues.

During the interview, Musk revealed the surgery with the second patient went "extremely well" and the implanted BCI is "working very well." Musk said Neuralink has detected 400 electrodes on the second patient's BCI, which are essentially the bridge between the device and the human brain's electrical signals.

Tractor beams are one of the most iconic pieces of science-fiction technology, most likely popularized through movies and TV shows such as Star Wars, Star Trek, and anything to do with advanced alien lifeforms operating UFOs.

While those pop-culture depictions of tractor beams are certainly very far away, researchers may be able to create a small tractor beam that would be used for health benefits. A team of researchers penned a new study in the scientific journal ACS Photonics, which details the creation of a tractor beam that's specifically designed to target cells that could lead to health complications. The invention would reduce the invasive nature of removing tissue through physical slicing, and thus, the chance of infection and further health complications.

The team used three strands of light that were twisted together like a Raspberry Twister, but the light formed together into a small tunnel or tube. These three forms of light are created by passing normal light through a surface that has an extremely thin nanopatterned silicon placed over a small plane of glass. The result is a triple helix solenoid beam that works like a tractor beam, except it's extremely thin.

NASA's Mars rover has discovered a rock on the surface of the Red Planet that shows possible signs of ancient life once existing on Earth's desolate neighbor.

The team monitoring the progress of NASA's Perseverance rover, which landed in the Jezero Crater in early 2021, is excited over the discovery of a rock that shows three signs of possible evidence of ancient microbial life once existing on Mars. The signs the rover discovered are often associated with the Earth's fossilized record of microbes living in the subsurface, and never before has NASA found all three together.

NASA explains via the above video that one of the first signs of possible microbial life is the discovery of calcium sulfate veins running up and down the rock. Calcium sulfate veins are "clear" evidence that water once ran through the rock. This discovery coincides with the overall theory that Mars was once home to large quantities of running water systems that caused the landscape observed by Perseverance to resemble dried up river systems similar to what is seen on Earth.

On July 11, SpaceX encountered a critical failure problem on one of its Falcon 9 rockets. The problem resulted in a Rapid Unscheduled Disassembly (RUD) protocol to be initiated, or boom.

SpaceX has taken to its website and X account to share an update on the review process following the failure of a Falcon 9 rocket. Notably, SpaceX's Falcon 9 is the company's workhorse rocket, having already launched 24 times this year and more than 350 times since its debut in 2010. During that time it has only experienced one catastrophic in-flight failure.

However, on July 11, a critical failure occurred during the first burn of Falcon 9's second-stage engine. SpaceX explains a liquid oxygen leak developed within the simulation around the upper stage engine, with engineers later discovering the cause of the leak was a crack in a sense line for a pressure sensor that's attached to the vehicle's oxygen system. The sense line cracked due to "high loading from engine vibration and looseness in the clamp that normally constrains the line."

NASA has taken to its website to detail newly snapped images of an exoplanet called Epsilon Indi Ab, which the space agency says is one of coldest exoplanets it has observed to date.

An international team of astronomers pointed Webb's extremely powerful infrared instruments at the exoplanet Epsilon Indi Ab, which is approximately 12 light-years away from Earth and within the constellation of Indus. The planet orbits the K-type star known as Epsilon Indi A, which is approximately the same age as our Sun, only slightly cooler. The team used Webb's MIRI instrument, which stands for Mid-Infrared Instrument, to directly image the exoplanet and reveal its interesting properties.

The space agency explains Epsilon Indi Ab is one of the coldest exoplanets to be directly detected, measuring an extremely freezing temperature of 35 degrees Fahrenheit, or 2 degrees Celsius. Notably, Epsilon Indi Ab is the closest planet to Earth that is more massive than Jupiter, and is the twelfth closest exoplanet to Earth known to date.
