A team of researchers at the Perelman School of Medicine at the University of Pennsylvania has discovered that obese mice, treated with the cytokine (a category of proteins) known as TSLP, reported significant fat and weight loss. Described as an “unforeseen finding,” researchers also said that the fat loss was in no way related to decreased food intake or faster metabolism. The treatment revealed, “TSLP prompted the immune system to release lipids through the skin’s oil-producing sebaceous glands.” 

The study is led by Taku Kambayashi, Associate Professor of Pathology and Laboratory Medicine at the University of Pennsylvania. He was joined by Ruth Choa, a fourth-year PhD medical student. Kambayashi said that despite being an unexpected discovery, the team has demonstrated that fat loss was possible by secreting calories from the skin in the form of energy-rich sebum. The professor added that the findings of the animal experiment also show that this could develop into a model for the treatment of obesity among people.  

Kambayashi said that they never thought the TSLP would have any impact on obesity itself. What they set out for was to find out if it impacted insulin resistance. “We thought that the cytokine could correct Type 2 diabetes, without actually causing the mice to lose any weight,” he said.

In order to see the effect of TSLP on Type 2 diabetes, the researchers administered on obese mice a viral vector to increase their bodies’ TSLP levels. Four weeks after the mice were administered injections, the team found that TSLP, besides affecting their diabetes risk, also reduced obesity in them. Compared to TSLP-treated mice, the control group continued to gain weight. The TSLP-treated mice lost 20 grams, going from 45 to just 25 grams in 28 days, the team said. 

Not just that, while the mice reported weight and fat loss, Kambayashi assumed that TSLP was perhaps sickening them. Upon further testing, the group realised that the mice receiving TSLP treatment were also eating 20 to 30 percent more. Besides, they also had similar energy expenditures, base metabolic rates, and activity levels compared to their non-treated counterparts.

Could this work on Humans?

The authors of the study said that in humans, shifting sebum release into “high gear” could feasibly lead to the “sweating of fat” and weight loss.

Kambayashi’s group next plans to test this hypothesis. He said that he doesn’t think humans naturally control their weight by regulating sebum production. “We may be able to hijack the process and increase sebum production to cause fat loss,” he said.

Rare Titan Shadow Transits Will Sweep Across Saturn in Summer 2025

Rare Titan Shadow Transits Will Sweep Across Saturn in Summer 2025

Saturn’s largest moon Titan will cast its shadow across the planet’s surface in a rare spectacle this summer. Over the coming months, observers on Earth may see a dark “hole” move across Saturn’s disk as Titan passes in front of the planet. This event is tied to a special alignment: roughly every 15 years, Saturn’s rings become edge-on to our view (a ring-plane crossing or equinox). Indeed, in March 2025 the rings briefly vanished as they lined up edge-on, setting the stage for Titan’s shadow to loom large on Saturn’s globe. After this year’s transit season, the configuration won’t recur until about 2040, making these transits uniquely unmissable.

Saturn’s Equinox and Titan’s Transits

According to Space.com, right now Saturn is near its equinox, meaning its tilted rings are edge-on to Earth. This geometry allows Titan’s shadow – a dark spot on Saturn – to sweep across the planet’s face, much like a lunar eclipse but on Saturn. Titan orbits Saturn about every 16 days, so during this alignment we can see its shadow cross Saturn’s disk repeatedly. In fact, roughly ten Titan shadow-transit events are expected during 2025. Three have already occurred (most recently on June 16), and seven more are forecast from July through early October 2025. When visible, each transit looks like a moving dark spot (a “hole”) on Saturn’s bright disk.

Viewing the Titan Shadow Transits

These transits are faint and require planning. A good telescope (at least 200× magnification) is needed to see Titan and its shadow. For viewers in North America, Saturn will be low in the pre-dawn sky during the event dates. According to Sky & Telescope, the remaining 2025 transit dates are July 2, July 18, August 3, August 19, September 4, September 20 and October 6 (local viewing times vary by location).

Early-season events last several hours, but the crossings shorten as the year goes on: by Oct. 6 the shadow is only visible briefly at the exact mid-transit moment. Observers should consult astronomy software and aim for clear skies on those dates, as any clouds or mist will obscure the subtle shadow.

NASA’s Chandra Reveals Stunning Multi-Wavelength Image of Andromeda Galaxy

NASA’s Chandra X-ray Observatory provides a new look at the Andromeda galaxy in this multi-wavelength image that includes X-ray, ultraviolet, optical, infrared, and radio images and illustrates the “collaboration of light” across the spectrum. The structure and future fate of the Milky Way are modelled with the help of Andromeda, which is 2.5 million light years away. This combined image not only shows high-energy radiation from a supermassive black hole but also provides a clear view of the arms and core of M31 in remarkable detail. The light is transformed into a sound with a sonification video, bringing another level of sensation.

Chandra X-ray Data Reveals Black Hole Flares and Dark Matter Legacy in New View of Andromeda

As per NASA’s Chandra team, the X-ray observations — alongside data from ESA’s XMM-Newton, NASA’s GALEX and Spitzer, Planck, IRAS, COBE, Herschel, and more — reveal distinct galactic features. Notably, a flare detected in 2013 from Andromeda’s supermassive black hole showed enhanced X-ray emission. The data also honours astronomer Vera Rubin, whose M31 rotation studies led to the first convincing evidence for dark matter. Rubin is now commemorated on a 2025 U.S. quarter.

Among the release features is a signature sonification, with different categories of light — X-ray, ultraviolet, optical, infrared, and radio — translated into sound tones. Volume is controlled by brightness, pitch by frequency position. The result is a sound map of the galaxy’s internal structure.

The Chandra programme for NASA’s Science Mission Directorate in Washington is managed by NASA’s Marshall Space Flight Centre in Huntsville, Alabama. Chandra’s overseer is the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.

With this updated M31 panorama in hand, astronomers are in for a beautiful sight, but the broader population is also treated to a sight and sound experience that transports us to our Milky Way’s closest galactic neighbour.

Could These Meteorites Be from Mercury? New Research Hints at Rare Discovery

Scientists have observed whether the meteorites can reach Earth from Mercury. Over thousands of meteorites from Mars and the Moon have been observed, but none have been from Mercury, despite it being a nearby rocky planet. A new study revealed Icarus suggests two meteorites, Ksar Ghilane 022 and Northwest Africa 15915, could belong to Mercurian origin. Such a kind of meteorite can offer a realistic opportunity to study the material of the surface of the planet, if the technical challenges and the cost of sending a spacecraft to Mercury are met.

New Meteorite Samples Show Strong Similarities

As per the new studies reported to Physics.org , Meteorite NWA 7325 and aubrites in the past were considered to be possibly from Mercury. However, the mineral composition of their samples has inconsistencies with the known surface data from the Messenger mission of NASA. Aubrites formed on a planet similar in size to Mercury, lacking spectral and chemical similarities, and further weakened as Mercurian fragments.

Ksar Ghilane 022 and NWA 15915, the new samples, share many traits of Mercury crust, with olivine, oldhamite, pyroxene, and minor albitic plagioclase. The oxygen composition of these matched with the aubrites, signalling a similar planetary origin and putting them among strong Mercurian members.

Key Differences Raise Scientific Questions

There are key differences even after that, and the two meteorites contain very little plagioclase than on the Mercury surface, and are about 4,528 million years older than Mercury’s surface material. If they are from Mercury, there is a possibility that they can represent an ancient crust which is no longer visible on the planet.

Future Missions and Scientific Verification

Relating a meteorite to a particular planet is quite difficult without direct samples. BepiColombo missions are orbiting Mercury currently, and can offer valuable insights to confirm meteorites source. Mercurian meteorites can get valuable insights into the formation, composition and history of the planet. There are further findings to be presented at the Meteoritical Society Meeting 2025 in Australia.
