We don’t wanna freak you out, but there’s a serious likelihood that dark matter could be in the room with you right now, and could even be passing through your body as you read this.
“Yeah, absolutely. It’s here,” Yeshiva University researcher Ed Belbruno told Futurism. “Where you’re sitting, you’re feeling, on some level which is beyond our senses… that force.”
It makes sense. Dark matter, which scientists have yet to observe or measure directly, is estimated to make up 95 percent of the universe. With a substance that prevalent, the likelihood that it’s made its way to Earth and into our homes and bodies seems high, right?
While it’s an exciting discovery, it falls short of demonstrating that carbon-based lifeforms once lived on the surface of the Red Planet. It is, however, a step in that direction.
“This experiment was definitely successful,” Maëva Millan, postdoctoral fellow at NASA’s Goddard Spaceflight Center and lead author of a new study published on Monday in the journal Nature Astronomy, told Inverse.
“While we haven’t found what we were looking for, biosignatures, we showed that this technique is really promising,” she added.

Materials scientists at the UCLA Samueli School of Engineering and colleagues from five other universities around the world have discovered the major reason why perovskite solar cells—which show great promise for improved energy-conversion efficiency—degrade in sunlight, causing their performance to suffer over time. The team successfully demonstrated a simple manufacturing adjustment to fix the cause of the degradation, clearing the biggest hurdle toward the widespread adoption of the thin-film solar cell technology.
A research paper detailing the findings was published today in Nature. The research is led by Yang Yang, a UCLA Samueli professor of materials science and engineering and holder of the Carol and Lawrence E. Tannas, Jr., Endowed Chair. The co-first authors are Shaun Tan and Tianyi Huang, both recent UCLA Samueli Ph.D. graduates whom Yang advised.
Perovskites are a group of materials that have the same atomic arrangement or crystal structure as the mineral calcium titanium oxide. A subgroup of perovskites, metal halide perovskites, are of great research interest because of their promising application for energy-efficient, thin-film solar cells.
NASA’s newly-launched X-ray hunting probe has snapped its first science image and — wow — it’s spectacular.
The Imaging X-ray Polarimetry Explorer (IXPE) probe launched Dec. 9, 2021, on a mission to observe objects like black holes and neutron stars in X-ray light, shedding much-anticipated light on the inner workings of the cosmos. The probe spent its first month in space checking out its various systems to get ready to capture its first images, and now the IXPE team has released its very first science image.
Developed by researchers in Saudi Arabia, the novel approach considers both the power yield and the solar module time to failure (TTF), among other factors. According to its creators, the model can be applied to all kinds of module and cell technologies.
It seems some people are using deepfake to misinform people.
Facebook and YouTube said Wednesday that they removed uploads of a deepfake video of Ukrainian President Volodymyr Zelensky that purported to show him yielding to Russia.
For the second time ever, SpaceX has used Starbase’s ‘Mechazilla’ tower and arms to stack a Starship upper stage on top of a Super Heavy booster.
This time around, though, SpaceX clearly learned a great deal from its second February 9th Starship stack and was able to complete the stacking process several times faster on March 15th. During the second attempt, depending on how one measures it, it took SpaceX around three and a half hours from the start of the lift to Starship fully resting on Super Heavy. With Stack #3, however, SpaceX was able to lift, translate, lower, and attach Starship to Super Heavy in just over an hour.
Oddly, SpaceX managed that feat without a claw-like device meant to grab and stabilize Super Heavy during stacking operations. For Stack #2, all three arms were fully in play. First, a pair of ‘chopsticks’ – giant arms meant to grab, lift, and even recover Starships and boosters – grabbed Ship 20, lifted it close to 100 meters (~300 ft) above the ground, rotated it over top of Super Heavy, and briefly paused. A third arm – known as the ship quick-disconnect or umbilical arm – swung in and extended its ‘claw’ to grab onto hardpoints located near the top of Super Heavy. Once the booster was secured, the ‘chopsticks’ slowly lowered Ship 20 onto Booster 4’s interstage and six clamps joined the two stages together.
