FRB 20190520B, a rare repeating FRB located in a 3.9 billion light-year-distance dwarf galaxy, has been studied using the FAST, CSIRO Parkes, Green Bank, and Murriyang radio telescopes. Results show that FRB 20190520B is surrounded by a highly magnetized environment. Additionally, the magnetic field was seen to reverse directions twice, which may be due to the source of the bursts going in and out of a stellar wind region as it moved through its orbit.

NASA’s James Webb Space Telescope has enabled a long-sought scientific breakthrough in solving the mystery behind Earth’s abundant water. With its efficient detection of gas - specifically water vapor - around a comet in the main asteroid belt, it has been demonstrated that water ice from the early solar system can be preserved in the warmer asteroid belt, inside the orbit of Jupiter. However, the lack of Carbon dioxide present in Comet Read was a surprise, and leads to new possibilities concerning the Comet's origin and other possible explanations.

Recently conducted research demonstrates that there has been a dramatic tenfold increase in the amount of sexual abuse imagery created with webcams since 2019. Cybercriminologists posed as children in chatrooms where adults attempted to lure them into sending videos. Many links sent contained possibilities of malware and phishing websites, with 41% leading to a Norwegian video conferencing platform--Whereby. It is urgent that parents and children are aware of the dangers that come with webcam technology.

U.S. climate envoy John Kerry recently expressed his doubts on oil and gas companies’ ability to develop technological breakthroughs that will allow the world to drill and burn fossil fuels without worsening climate change. Oil and gas companies hold on to the possibility of making these breakthroughs to prevent increasing emissions, but many experts are skeptical of the potential. Without these solutions, countries will have to make a swift switch to renewable energy sources in order to prevent climate change.

Brigham and Women's Hospital conducted a study to uncover the molecular mechanisms of Th17 cell generation. This study found a role for purine metabolite xanthine in the generation of Th17 cells, even without the presence of microbes and suggested cells with protective properties. It is yet to be seen whether the amount of xanthine found in foods like coffee, tea, and chocolate will have a helpful or harmful effect in the gut.

Stratolaunch's Roc, the world's biggest airplane owned by late entrepreneur Paul Allen, has successfully dropped a hypersonic test vehicle, paving the way for its first hypersonic flight in just a few months. The test was part of a strategy change from air-launchable rockets to hypersonic vehicles for the U.S. Department of Defense. After a four-hour-long flight, the Roc was able to deliver its payload safely and is now inching closer to achieving hypersonic flight.

This study investigates the transition from single cell organisms to robust multicellular organisms by researching snowflake yeast. After generations of lab evolution, the snowflake yeast adapted to become physically stronger and larger, providing insights into the biophysical limitations of size and toughness of multicellular life. This is the first major report of the ongoing MuLTEE experiment, which the team hopes to run for decades.

Older adults with depression are aging faster than their peers, researchers have found, with worse cardiovascular and cognitive performance associated with accelerated aging caused by depression. New therapies are being explored to reduce disability associated with late-in-life depression and slow down biological aging.

Tractor beams are a once fictional technology which have now become a reality thanks to recent advances in physics and technology. They use laser or sound waves to manipulate particles, molecules, or larger objects from a distance and have potential applications in fields like healthcare and precision manufacturing. The physics behind how they work involves momentum transfer between the tractor beam and the object it is manipulating.

Google announced that it would be infusing its dominant search engine with more advanced artificial intelligence technology in response to one of the biggest threats to its long-established position as the internet's main gateway. The new technology is called Bard and will involve putting AI-driven search results into the search engine.This AI-powered search engine would need to balance between pushing the boundaries of cutting-edge technology and staying reliable, as well as ensuring that AI-generated summaries will sound more factual than conversational.

The nuclear physics group at the University of Illinois Urbana-Champaign are looking for new physics evidence in neutrons. To do so, they are participating in the nEDM experiment which measures the neutron's electric dipole moment. A grant from the Department of Energy will fund the researchers to develop sensors based on nitrogen-vacancy diamond, to measure these subtle changes accurately. In addition, the material’s quantum properties make it a promising candidate for quantum sensing and quantum memory.

A study published on diaTribe Learn found that a real-time continuous glucose monitor (CGM) plus an insulin pump had a "significantly" higher time in range of 70 percent for children suffering from type 1 diabetes. The article offered the Medtronic’sMiniMed 770G pump and a non-profit, Kyler Cares, was also founded to provide grants for CGMs and insulin pumps for those who can not afford them. The study was published in the JAMA journal and showed that the use of real-time CGM compared with intermittently scanned CGM was associated with improved glycemic control, showing the importance of policy changes for diabetic treatments.
