  • Scientists discover proteins that could help fight cancer, slow aging-Xinhua

    SYDNEY, July 3 (Xinhua) — Australian scientists have identified a group of proteins that could transform approaches to treating cancer and age-related diseases.

    Researchers at the Children’s Medical Research Institute (CMRI) in Sydney have discovered that these proteins play a crucial role in controlling telomerase, an enzyme responsible for protecting DNA during cell division, according to a recent statement by the CMRI, which led the research.

    This breakthrough clarifies how telomerase both supports healthy aging and fuels cancer cell growth, highlighting new possibilities for treatments that slow aging or stop cancer by targeting these newly identified proteins.

    Telomerase helps maintain the ends of chromosomes, known as telomeres, which are vital for genetic stability. While telomerase is essential for the health of stem cells and certain immune cells, cancer cells often exploit this enzyme to grow uncontrollably, said the study published in Nature Communications.

    The team discovered that three proteins — NONO, SFPQ, and PSPC1 — guide telomerase to chromosome ends; disrupting them in cancer cells prevents telomere maintenance, potentially stopping cancer cell growth.

    “Our findings show that these proteins act like molecular traffic controllers, making sure telomerase reaches the right destination inside the cell,” said Alexander Sobinoff, the lead author of the study.

    Hilda Pickett, head of CMRI’s Telomere Length Regulation Unit and the study’s senior author, noted that understanding how telomerase is controlled opens new possibilities for developing treatments targeting cancer, aging, and genetic disorders linked to telomere dysfunction.

  • UF students are bending metal with lasers to build massive structures in orbit

    UF students are bending metal with lasers to build massive structures in orbit

    In the vast vacuum of space, Earth-bound limitations no longer apply. And that’s exactly where UF engineering associate professor Victoria Miller, Ph.D., and her students are pushing the boundaries of possibilities.

    In partnership with the Defense Advanced Research Projects Agency, known as DARPA, and NASA’s Marshall Space Flight Center, the University of Florida engineering team is exploring how to manufacture precision metal structures in orbit using laser technology.

    “We want to build big things in space. To build big things in space, you must start manufacturing things in space. This is an exciting new frontier,” said Miller.

    An associate professor in the Department of Materials Science & Engineering at UF’s Herbert Wertheim College of Engineering, Miller said the project called NOM4D – which means Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design – seeks to transform how people think about space infrastructure development. Picture constructing massive structures in orbit, like a 100-meter solar array built using advanced laser technology.

    “We’d love to see large-scale structures like satellite antennas, solar panels, space telescopes or even parts of space stations built directly in orbit. This would be a major step toward sustainable space operations and longer missions,” said team member Tianchen Wei, a third-year Ph.D. student in materials science and engineering.

    UF received a $1.1 million DARPA contract to carry out this pioneering research over three phases. While other universities explore various aspects of space manufacturing, UF is the only one specifically focused on laser forming for space applications, Miller said.

    A major challenge of the NOM4D project is overcoming the size and weight limitations of rocket cargo. To address these concerns, Miller’s team is developing laser-forming technology to trace precise patterns on metals to bend them into shape. If executed correctly, the heat from the laser bends the metal without human touch; a key step toward making orbital manufacturing a reality.

    “With this technology, we can build structures in space far more efficiently than launching them fully assembled from Earth,” said team member Nathan Fripp, also a third-year Ph.D. student studying materials science and engineering. “This opens up a wide range of new possibilities for space exploration, satellite systems and even future habitats.”

    Miller said laser bending is complex but getting the correct shape from the metal is only part of the equation.

    “The challenge is ensuring that the material properties stay good or improve during the laser-forming process,” she said. “Can we ensure when we bend this sheet metal that bent regions still have really good properties and are strong and tough with the right flexibility?”

    To analyze the materials, Miller’s students are running controlled tests on aluminum, ceramics and stainless steel, assessing how variables like laser input, heat and gravity affect how materials bend and behave.

    “We run many controlled tests and collect detailed data on how different metals respond to laser energy: how much they bend, how much they heat up, how the heat affects them and more. We have also developed models to predict the temperature and the amount of bending based on the material properties and laser energy input,” said Wei. “We continuously learn from both modeling and experiments to deepen our understanding of the process.”

    The research started in 2021 and has made significant progress, but the technology must be developed further before it’s ready for use in space. This is why collaboration with the NASA Marshall Space Center is so critical. It enables UF researchers to dramatically increase the technology readiness level (TRL) by testing laser forming in space-like conditions inside a thermal vacuum chamber provided by NASA. Fripp leads this testing using the chamber to observe how materials respond to the harsh environment of space.

    “We’ve observed that many factors, such as laser parameters, material properties and atmospheric conditions, can significantly determine the final results. In space, conditions like extreme temperatures, microgravity and vacuums further change how materials behave. As a result, adapting our forming techniques to work reliably and consistently in space adds another layer of complexity,” said Fripp.

    Another important step is building a feedback loop into the manufacturing process. A sensor would detect the bending angle in real time, allowing for feedback and recalibration of the laser’s path.

    As the project enters its final year, finishing in June of 2026, questions remain — especially around maintaining material integrity during the laser-forming process. Still, Miller’s team remains optimistic. UF moves one step closer to a new era of construction with each simulation and laser test.

    “It’s great to be a part of a team pushing the boundaries of what’s possible in manufacturing, not just on Earth, but beyond,” said Wei.

  • CCD Tech used on latest ESA Sentinel-4 Mission

    CCD Tech used on latest ESA Sentinel-4 Mission

    Teledyne Space Imaging in Chelmsford, UK, has designed, tested, and manufactured two charge-coupled device (CCD) image sensors which were delivered to Airbus GmbH for the European Space Agency’s (ESA) Sentinel-4 air-quality monitoring mission. Sentinel-4, mounted on the Meteosat Third Generation Sounder (MTG-S) satellite, successfully launched on 1 July from Cape Canaveral in Florida, US, as part of the European Union’s Copernicus programme, led by the European Commission (EC) in partnership with ESA.

    This marks the second launch in just one week featuring detector technology from Teledyne Space Imaging. The Japanese Global Observing SATellite for Greenhouse gases and Water cycle (GOSAT-GW) mission, which launched on 28 June 2025, included two CIS120 sensors from Teledyne.

    Mission Purpose

    Sentinel-4 incorporates two different types of CCD sensors within its Ultraviolet-Visible-Near-Infrared (UVN) imaging spectrometer instrument. The CCD374 sensor operates at ultraviolet and visible wavelengths, while the CCD376 sensor provides images in the near-infrared wavelength. From its geostationary orbit, the Sentinel-4 mission will deliver data on a range of trace gases, including ozone, nitrogen dioxide, and sulphur dioxide.

    The Sentinel-4 mission will transmit data on tropospheric constituents over Europe every hour for use in air quality applications and monitoring projects on the ground. This data will provide valuable insights into climate, air pollutants, and ozone/surface ultraviolet (UV) applications, supporting ongoing research into protecting public health.

    Project Involvement and Development

    Teledyne Space Imaging first became involved in the Sentinel-4 project during its initial development phase in 2009, which included detector design, prototype manufacturing, and radiation testing. The second phase, which began in 2012, involved the design and validation of the flight detectors, as well as design updates based on the results of the first phase. The final phase, completed in 2019, was the flight model phase, during which Teledyne Space Imaging manufactured the flight deliverables for the customer. Reliability testing ensured the detectors will survive beyond the expected 10-year duration of the mission.

    Ross Mackie, Principal Project Lead Engineer at Teledyne Space Imaging, said: “Our sensors were selected due to the heritage of our work on Sentinel-2 and -3, as well as internal developments that met the needs of this mission. Our detectors fulfilled all the mission’s requirements for operation in various wavelengths, giving us the edge in developing these exciting products for Sentinel-4. We were able to offer a bespoke approach to provide the best possible results for the mission.”

    Tracy Phillips, Teledyne’s Principal Project Manager responsible for the execution and performance of the project, added: “Managing the CCDs for the Sentinel-4 mission was one of my first projects at Teledyne, and it was fascinating to learn about the technological capabilities of our detectors. It’s very exciting to work with such advanced sensors that will contribute to gathering vital information about our planet, ultimately better protecting Earth and helping save lives.”

  • Possible interstellar visitor headed toward Sun discovered by UH telescope

    Possible interstellar visitor headed toward Sun discovered by UH telescope

    Reading time: 3 minutes

    Closeup visual of 3I/ATLAS

    A telescope operated by the University of Hawaiʻi has detected the third known interstellar (from outside our solar system) object to enter our solar system. Researchers say that it poses no danger to Earth.

    Full ATLAS image and a cutout of the discovery image

    The discovery was made by UH’s NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Rio Hurtado, Chile. ATLAS is a global network of four telescopes managed by the UH Institute for Astronomy that scan the skies for asteroids that could pose a threat to Earth. According to researchers, the object is moving right through the Milky Way, making it difficult to distinguish amidst all the stars. But researchers say this is one of ATLAS’s strengths.

    “Spotting a possible interstellar object is incredibly rare, and it’s exciting that our UH-operated system caught it,” said John Tonry, UH Institute for Astronomy astronomer and professor. “These interstellar visitors provide an extremely interesting glimpse of things from solar systems other than our own. Quite a few come through our inner solar system each year, although 3I/ATLAS is by far the biggest to date. The chances of one actually hitting the Earth are infinitesimal, less than 1 in 10 million each year, but ATLAS is continually searching the sky for any object that might pose a problem.”

    Full discovery image

    The newly identified object, designated A11pl3Z, was added to the International Astronomical Union’s Near-Earth Object confirmation list on July 1, and a Minor Planet Electronic Circular was just released that names it 3I/ATLAS. It is currently soaring toward the sun on a trajectory and with speed that reveals that it originated from outside our solar system, and will leave the solar system again after passing the Sun. Early estimates suggest the object may be as large as 12 miles in diameter. Researchers say it will make its closest approach to the sun—about twice the distance from Earth—in October, traveling at more than 150,000 miles per hour.

    Although 3I/ATLAS appears on the Near-Earth Object list, there is no risk of collision with Earth or even a close pass. It is sobering, however, that if it struck the Earth (and it will not) it would create an explosion more than 100 times greater than the asteroid that killed the dinosaurs. Researchers suspect that 3I/ATLAS is a comet and it should show increasing activity as it gets closer to the Sun, although it will never get warm enough to make a naked eye display.

    The four-telescope ATLAS system is the first line of defense in surveying hazardous asteroids capable of monitoring the entire dark sky every 24 hours. Read this UH News story for more about ATLAS.

    Visitor number 3?

    This marks the third likely interstellar visitor, following the discoveries of ʻOumuamua in 2017 and comet 2I/Borisov in 2019. ʻOumuamua was first detected by UH’s Pan-STARRS1 telescope on Haleakalā and became the first object to receive an official interstellar designation. It caught global attention with its strange, elongated shape and unexpected acceleration as it exited the solar system. Although it showed no visible tail, its motion suggested comet-like behavior. Most scientists now agree that it was a natural object, likely a comet from another star system, although its exact nature is still debated.

    SwRI, UTSA selected by NASA to test electrolyzer technology aboard parabolic flight

    Research aims to address NASA’s technology shortfalls and support future missions to Moon, Mars Grant and Award Announcement

    Southwest Research Institute SAN ANTONIO — July 1, 2025 —Southwest Research Institute (SwRI) and The University of Texas at San Antonio (UTSA) will receive a $500,000 award from NASA’s TechLeap Prize program to flight test novel electrolyzer technology designed to improve the production of propellants and life-support compounds on the Moon, Mars or near-Earth asteroids. The project, known as the Mars Atmospheric Reactor for Synthesis of Consumables (MARS-C), is led by SwRI’s Kevin Supak and Dr. Eugene Hoffman and UTSA’s Dr. Shrihari “Shri” Sankarasubramanian.

    TechLeap prizes are designed to support future missions by advancing transformative solutions that address NASA’s technology shortfalls. The SwRI/UTSA group is one of nine winners funded to test their payloads on suborbital, hosted orbital or parabolic flights. The program aims to accelerate the technology testing timeline, allowing completion within a year of the award.

    SwRI and UTSA will evaluate the performance of a patent-pending electrolyzer developed with NASA support by Sankarasubramanian, an assistant professor in UTSA’s Department of Biomedical and Chemical Engineering, and his team. The device applies a voltage across two electrodes to drive the electrochemical conversion of a simulated Martian brine and carbon dioxide into methane and other hydrocarbons. This technology is designed to use local resources on the Moon or Mars to produce fuel, oxygen and other life support compounds needed for long-term human habitation..

    The work builds on previous research conducted by SwRI, which involved studying boiling processes under partial gravity aboard parabolic flights. Designed to understand how liquids might behave on lunar or Martian surfaces, the research demonstrated that partial gravity affects surface bubble dynamics, which can affect gas production rates.

    Supak, said:

    In a partial gravity environment, like the Moon or Mars, a reduced buoyancy effect on gas bubbles in an electrolyzer poses challenges that aren’t present on Earth,

    “We lack an understanding about chemical processes that leverage bubble nucleation in low gravity, which is the gap we aim to fill.”

    To address this, SwRI and UTSA will integrate the technology into an existing SwRI-built flight rig and test it aboard a parabolic flight, capitalizing on the Institute’s successful history testing technology in reduced gravity aircraft and suborbital spacecraft.

    Sankarasubramanian, said:

    We plan to acquire bubble nucleation and fluid motion videos in an operating electrolyzer during the parabolic flight,

    “Understanding these processes can help us improve the overall efficiency and performance of these electrolyzers.”

    After the flight rig is complete, SwRI will conduct ground tests before the parabolic flight to establish operating procedures and ensure a successful demonstration. The flight is currently planned for 2026.

    Supak, said:

    Humans have an intrinsic drive to push the boundaries of what’s possible.

    “Exploring space catalyzes technological advancements that have far-reaching benefits in our daily lives — often unanticipated innovations arise as a direct result of overcoming the unique challenges of space exploration.Establishing permanent presences on other planetary bodies could pave the way for unprecedented scientific discoveries and technological breakthroughs.”

  • Research Ties Sea Ice Loss to Antarctic Ice Shelf Calving

    Published in Nature Geoscience, the study, led by the University of Adelaide and University of Melbourne, found long periods of sea ice loss surrounding the ice shelves occurred in the six to 18 months prior to calving, as well as the collapse of the ‘landfast’ sea ice attached to the ice shelves only weeks prior to the calving events.

    “Sea ice is retreating at an unprecedented rate all around Antarctica and our work suggests this will put further pressure on already thinned and weakened ice shelves,” said Professor Luke Bennetts, from the University of Melbourne.

    “This could lead to more large-scale calving events, with profound implications for the future of global sea levels.”

    The Antarctic Ice Sheet is the thick layer of ice that sits on top of Antarctica. It holds enough fresh water to raise current sea levels by more than 50 metres.

    Ice shelves are floating platforms that form as glaciers flow off the Antarctic continent onto the ocean, whereas sea ice forms when the surface of the ocean freezes.

    “Except for a relatively short period around summer, sea ice creates a protective barrier between the ice shelves and the potentially damaging swells of the Southern Ocean. Without this barrier, the swells can bend and flex pre-weakened ice shelves until they break,” Professor Bennetts said.

    Previous research has shown that warming temperatures are causing more rapid melting and more frequent ‘calving’ of icebergs from some ice shelves.

    “Increased melting and calving does not directly increase sea levels, as the ice shelves are already floating on the ocean, but it reduces the ability of the ice shelves to push back against the glacial flow into the ocean, which does raise sea levels,” Professor Bennetts said.

    Nathan Teder, a PhD candidate at the University of Adelaide who led the study, said his team also developed a novel mathematical model to quantify the ice shelf flexing caused by the huge Southern Ocean swells.

    “There is currently no observation system that allows for long-term recording of swell waves that pass through Antarctic sea ice to reach ice shelves, so mathematical modelling is an essential link in quantifying the connection between ice shelf stability and changes in local sea ice and ocean conditions,” said Mr Teder.

    The research was funded by the Australian Antarctic Science Program and the Australian Research Council and collaborators included the University of Melbourne, the University of Adelaide, the Australian Bureau of Meteorology, the University of Tasmania, and the Australian Antarctic Division.

  • Weather Satellites Can Even Study the Weather Over on Venus

    Weather Satellites Can Even Study the Weather Over on Venus

    In 2014 and 2016, the Himawari-8 and -9 satellites were launched into orbit. Owned and operated by the Japan Meteorological Agency (JMA), these satellites monitor global weather patterns and atmospheric phenomena using their multispectral Advanced Himawari Imagers (AHIs). In a recent study, a team led by the University of Tokyo presented infrared images that capture changes in Venus’ atmosphere, revealing unseen temperature patterns in its cloud tops. The results show that meteorological satellites can complement observations of Venus’ atmosphere by robotic missions and ground-based telescopes.

    The team was led by Gaku Nishiyama, a visiting postdoctoral researcher at the University of Tokyo and the Institute of Space Research at the German Aerospace Center (DLR). The Max Planck Institute for Extraterrestrial Physics (MPE), National Institute of Advanced Industrial Science and Technology, the University of Tokyo’s Institute of Astronomy, Graduate School of Frontier Sciences, the National Astronomical Observatory of Japan (NAOJ), Institute of Space and Astronautical Science (ISAS) at the Japan Aerospace Exploration Agency (JAXA), the European Space Research and Technology Centre (ESTEC), and multiple universities.

    Scientists have studied Venus’ atmosphere for decades, hoping to learn more about the dynamics of the hottest planet in the Solar System. However, several mysteries are still unresolved, such as its thermal tides and planetary-scale waves. As Nishiyama and his colleagues indicated in their study, multi-band spectral monitoring of Venus’ atmosphere would shed light on these and related phenomena. This presents multiple challenges, however, and robotic probes sent to Venus in the past decade have been limited to either single-band imagery or short observation periods. As Nishiyama said in a UTokyo press release:

    The atmosphere of Venus has been known to exhibit year-scale variations in reflectance and wind speed; however, no planetary mission has succeeded in continuous observation for longer than 10 years due to their mission lifetimes. Ground-based observations can also contribute to long-term monitoring, but their observations generally have limitations due to the Earth’s atmosphere and sunlight during the daytime.

    Nishiyama and his colleagues believe meteorological satellites could fill this gap thanks to their extended lifetimes and capabilities. The Himawari satellites are scheduled to remain operational for more than a decade (until 2029). In addition, the AHI instruments provide multi-band infrared coverage of Earth’s atmosphere to obtain temperature information from different altitudes, which is essential to tracking and predicting weather patterns. Lastly, the geostationary satellites can obtain images of the turbulent atmosphere when they are aligned with Earth and Venus.

    To demonstrate the potential of these missions, the team used data from the Himawari-8 and -9 satellites to map the temporal dynamics of Venus’ atmosphere and create a comparative analysis with previous datasets. This consisted of extracting all the AHI images where Venus was visible in the distance (437 images in total) to create a dataset. This allowed them to track temperature variations in multiple infrared bands in Venus’ cloud tops over time. This was then analyzed on daily and annual timescales to discern variability in Venus’ thermal tides and planetary-scale waves.

    Their analysis confirmed that both the tides and waves are subject to changes in amplitude over time, which appear to decrease with altitude. Moreover, it allowed them to identify calibration discrepancies in data retrieved by previous planetary missions. Last, the results suggest that variations in thermal tide amplitude could be linked to variations in the structure of Venus’ atmosphere that occur every decade or so. However, the limited temporal resolution of the AHI data makes it very difficult to determine the physics behind these variations at this time.

    Nevertheless, Nishiyama and his team believe their analysis method will provide vital data about Venus until future planetary missions are sent there. At present, there are six missions under development worldwide, including NASA’s Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy (VERITAS) orbiter and the Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) probe, and the ESA’s EnVision orbiter. In the meantime, Nishiyama and his colleagues are already contemplating how their research using multi-band spectral data from Earth observation satellites could be applied to the study of other planets:

    I think that our novel approach in this study successfully opened a new avenue for long-term and multi-band monitoring of solar system bodies. This includes the moon and Mercury, which I also study at present. Their infrared spectra contain various information on physical and compositional properties of their surface, which are hints at how these rocky bodies have evolved until the present. We hope this study will enable us to assess physical and compositional properties, as well as atmospheric dynamics, and contribute to our further understanding of planetary evolution in general.

    The paper that details their findings appeared in Earth, Planets and Space on June 30th.

  • Recently-Discovered Exoplanet Triggers Flares on Its Parent Star

    Recently-Discovered Exoplanet Triggers Flares on Its Parent Star

    The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface, heating and inflating the planet’s atmosphere, according an analysis of data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and ESA’s CHaracterising ExoPlanets Telescope (CHEOPS).

    An artist’s impression of the young planetary system HIP 67522. Image credit: J. Fohlmeister, AIP.

    HIP 67522 is a G0-type star located about 417 light-years away in the constellation of Centaurus.

    Otherwise known as HD 120411, 2MASS J13500627-4050090 and TYC 7794-2268-1, the star is a member of the Scorpius-Centaurus stellar association.

    HIP 67522 is approximately 17 million years old, and hosts two young exoplanets.

    The inner planet, HIP 67522b, orbits the star once every 7 days and is about 10 times the diameter of Earth, or close to that of Jupiter.

    Using five years of data from NASA’s TESS and ESA’s CHEOPS telescopes, ASTRON astronomer Ekaterina Ilin and her colleagues took a closer look at the HIP 67522 system.

    They found that the planet and its host star form a powerful but likely a destructive bond.

    In a manner not yet fully understood, the planet hooks into the star’s magnetic field, triggering flares on the star’s surface; the flares whiplash energy back to the planet.

    Combined with other high-energy radiation from the star, the flare-induced heating appears to have increased the already steep inflation of the planet’s atmosphere.

    This might well mean that the planet won’t stay in the Jupiter size-range for long.

    One effect of being continually pummeled with intense radiation could be a loss of atmosphere over time.

    In another 100 million years, that could shrink the planet to the status of a hot Neptune, or, with a more radical loss of atmosphere, even a sub-Neptune, a planet type smaller than Neptune that is common in our Galaxy but lacking in our Solar System.

    “We’ve found the first clear evidence of flaring star-planet interaction, where a planet triggers energetic eruptions on its host star,” said Dr. Ilin, first author of a paper published in the journal Nature.

    “What’s particularly exciting is that this interaction has persisted for at least three years, allowing us to study it in detail.”

    “This type of star-planet interaction has been expected for a long time, but getting the observational evidence was only possible with this large space telescope dataset,” said Dr. Katja Poppenhäger, an astronomer at the Leibniz-Institut für Astrophysik Potsdam and the Universität Potsdam.

    “The planet is essentially subjecting itself to an intense bombardment of radiation and particles from these induced flares,” said Dr. Harish Vedantham, an astronomer at ASTRON.

    “This self-inflicted space weather likely causes the planet’s atmosphere to puff up and may dramatically accelerate the rate at which the planet is losing its atmosphere.”

    In an accompanying paper in the journal Astronomy & Astrophysics, the astronomers confirm that HIP 67522 is a magnetically active star with strong radio wave emission powered by its magnetic field.

    They observed the star at low radio frequencies for about 135 hours with the Australian Telescope Compact Array (ATCA), revealing it as a bright and bursty source of radio waves.

    At the same time, they found no signs of radio wave flares that could be attributed to the interaction of the star with the planet.

    “The non-detection is compatible with expectations that the planet-induced flares are too faint to be detected by ATCA, in line with the Nature paper’s conclusion of magnetic star-planet interaction driving flaring activity,” they said.
