Virtual clothing trials are the next big thing that can bring fashion and technology together. Computer scientists all around the world are trying to experiment with deep-learning techniques that can be used to virtually dress a 3D avatar (digital versions of humans). Developments in this field are being made in India too. Two researchers at TCS Research India have come up with a deep learning technique called DeepDraper that can predict how clothing items will adapt to the contours of a person’s body. While this technology isn’t new, researchers claim that the new technique is more precise. Therefore, it allows a person to better understand how an item of clothing will look on their body.

This technique was presented at the International Conference on Computer Vision (ICCV) Workshop, this year. 

Brojeshwar Bhowmick, one of the researchers behind DeepDraper, explained how the technique works.

“DeepDraper is a deep learning-based garment draping system that allows customers to virtually try garments from a digital wardrobe onto their own bodies in 3D,” he told TechXplore. 

The virtual draping is done after analysing a photo or a short video of a customer to estimate their 3D body shape, pose, and body measurements. It gets data about a garment from the digital wardrobe of a seller. The tech feeds the customer’s physical estimates to a neural network that predicts how the garment will look on the person’s 3D avatar.

The researchers evaluated their DeepDraper technique in a series of tests that proved to be better and more realistic with their estimates. The system was also able to drape garments of different sizes on human bodies of all shapes and different various characteristics.

Bhowmick said, “Another important feature of DeepDraper is that it is very fast and can be supported by low-end devices such as mobile phones or tablets.” The researchers had wanted to create a lightweight system that required low memory and computational power so that it could run in real-time.

“DeepDraper is nearly 23 times faster and nearly 10 times smaller in memory footprint compared to its close competitor Tailornet,” Bhowmick said.

This feature would allow it to be used on online clothing websites.

Currently, DeepDraper drapes the outfit on a static human body. Researchers are planning to experiment with human movements and animated draping. They are also planning to improve the technology to drape loose and multilayered garments such as dresses, gowns, t-shirts with jackets, and more.

Dark Dwarfs: New Star-Like Objects May Reveal Nature of Dark Matter

Astronomers predict an unseen class of star-like bodies called “dark dwarfs” near our galaxy’s center. A new study suggests these objects could shine thanks to annihilating dark matter, not nuclear fusion. Dark matter makes up about a quarter of the universe and interacts via gravity. If WIMP-like dark matter particles collect in a brown dwarf, they would annihilate and heat it, causing a faint glow. Dark dwarfs would be too light to fuse hydrogen, but would keep lithium-7 in their atmospheres, offering a signature. This prediction comes from a JCAP study. The discovery of one could reveal dark matter’s nature.

Predicted Dark Dwarf Properties

According to the paper, sub-stellar objects just below the hydrogen-burning threshold would be powered by dark matter. The authors find that the minimum mass for hydrogen fusion shifts above ∼0.075 M⊙ in dense dark-matter environments, so lighter brown dwarfs instead become stable dark-matter–powered stars (‘dark dwarfs’) via WIMP annihilation inside them. They predict such objects only appear in regions with extremely high dark-matter density, like the Galactic center (ρ_DM ≳ 10^3 GeV/cm^3), because further out the halo is too tenuous. Crucially, dark dwarfs should retain lithium-7 in mass ranges where ordinary brown dwarfs burn it away, providing a clear observational signature.

Observational Prospects and Implications

Sakstein notes that powerful telescopes like the James Webb Space Telescope might even already detect extremely cold objects like dark dwarfs near the galactic center. Alternatively, astronomers could survey brown dwarf populations for a rare sub-class with anomalous lithium content. Notably, even one confirmed dark dwarf would strongly favor heavy, self-annihilating dark matter.

Sakstein explains that finding dark dwarfs would provide “compelling evidence” for dark matter that is massive and interacts with itself – essentially WIMPs or similar particles. He notes that lighter candidates (like axions) would not produce such stars, so a dark dwarf discovery would disfavor those models. While not a proof of WIMPs, a dark dwarf detection would imply dark matter behaves like WIMPs (heavy and weakly interacting). Indeed, future surveys and JWST observations will also test these predictions.

NASA Astronaut Captures Rare Red Sprite Over Storm from Space Station

NASA Astronaut Captures Rare Red Sprite Over Storm from Space Station

In early July 2025, NASA astronaut Nichole “Vapor” Ayers snapped a rare image of a giant red “sprite” phenomenon erupting above a thunderstorm, as she orbited 250 miles (400 km) above Earth. Sprites are brief, luminous columns caused by powerful lightning discharges far below. Ayers noted that having the ISS vantage makes for a “great view above the clouds” and helps scientists analyze these elusive events. This sprite appeared over storm clouds spanning Mexico and the southern U.S. on July 3, 2025. The sighting coincides with NASA’s Spritacular citizen-science project, which crowdsources photos of sprites and other upper-atmosphere flashes.

Rare ‘Sprite’ Phenomenon Explained

According to NASA, sprites are one of the “least understood” and most visually striking upper-atmosphere phenomena. They are brief columns of red light that flash high above thunderclouds, triggered by powerful lightning strikes. Data show sprites often form around 50 miles (80 km) altitude above Earth. These fleeting bursts take varied shapes – tendrils, plumes or towering columns of red light.

In Ayers’s photo, the sprite looks like an inverted scarlet umbrella extending into the sky. Each sprite flash lasts only a few milliseconds, so every image provides valuable data. Observations from orbit and the ground are steadily building a clearer picture of these mysterious storm-driven events. For example, NASA’s Juno mission even recorded sprite-like flares in Jupiter’s atmosphere, suggesting similar lightning processes on other worlds.

Crowdsourcing Sprites

To gather more data on sprites, NASA launched the Spritacular citizen-science project. Through Spritacular, volunteers with cameras can submit photos of upper-atmosphere flashes for research. The project’s website reports over 800 volunteers from 21 countries have uploaded about 360 sprite sightings since its 2022 launch. Each contribution helps scientists map where and how sprites occur. Ayers’s ISS photo adds a valuable perspective that complements citizen reports.

Space.com notes that multiple ISS crew members have begun photographing sprites from orbit, bolstering the data. Spritacular principal investigator Dr. Burcu Kosar says the project “will bridge the gap” between casual observers and researchers. NASA scientists say many questions about how and why sprites form “remain unanswered”, so more images could soon help decode the mystery.

Progress 92 Spacecraft Docks at ISS with Vital Supplies for Expedition 73

The progress of 92 spacecraft, which is unpiloted, reached the space-facing port of the Poisk of the orbiting laboratory at 2:55 a.m. IST on Sunday, July 5, 2025. At 5:25 p.m. EDT, Saturday, July 5, 2025, the spacecraft landed. The spacecraft launched a 1:02 a.m. IST on July 4, 2025, on a Soyuz rocket from Kazakhstan’s Baikonur Cosmodrome. This spacecraft by Roscosmos is for providing tons of food, fuel and other supplies for the Expedition 73 crew on the International Space Station.

Six-Month Docking to Aid Research and Waste Management on ISS

As reported by NASA, it will be there on the dock for around six months before its departure and re-entry into the atmosphere of the Earth to dispose of the trash that the crew has loaded. This spacecraft includes a wide variety of essential items for astronomers. Apart from food and fuel, there are some equipment and spare parts also which are needed by the astronauts. Such items help the astronauts to perform their daily activities and conduct the planned experiments in space. It would be very difficult to maintain the life support and let the operations continue without any hampering.

Progress 92 Delivers Crucial Supplies to Support Expedition 73

Dr. Natalia Sergeyevna, the Roscosmos scientist, said in a statement that this successful docking portrays our strength in the continuous support to the ISS for the successful completion of Expedition 73. Every cargo mission is crucial and needs to ensure safety, health, and productivity. NASA praised the mission, calling the Progress Cargo deliveries a key part of keeping long-duration space missions going in a smooth manner.

Along with the everyday needs, the cargo also carried the materials for research related to health, plant growth, space materials and fluid dynamics. Scientists can better understand how living and working in space impacts their bodies and the milieu.

Progress 92 will stay docked at the ISS for about six months. After the work, the spacecraft will undock and make its re-entry into the atmosphere of the Earth and burn up safely. Cargo missions not just supply but also manage waste, keeping the ISS efficient and clean.
