What if our universe is not the only one? What if it is just a tiny bubble inside a much larger and more complex reality? This is the idea behind the bubble universe theory, which suggests that our universe is one of many possible universes that exist inside a black hole.

What is a bubble universe?

A bubble universe is a hypothetical region of space that has different physical laws and constants than the rest of the multiverse. The multiverse is the collection of all possible universes that exist or could exist. A bubble universe could form when a quantum fluctuation creates a tiny pocket of space with different properties than its surroundings. This pocket could then expand and inflate into a large and isolated universe, like a bubble in a glass of water.

A team of horticulturists, bio-breeders and agriculture specialists affiliated with a host of institutions across China has produced sweeter tomatoes without sacrificing size, weight or yield by altering two of their genes. In their study, published in the journal Nature, the group modified the genes of a tomato variant that coded for proteins that lowered levels of enzymes related to sugar production.

In an epic story of survival witnessed by the NASA/ESA Hubble Space Telescope, one of our nearest galactic neighbours has crashed through the Milky Way galaxy’s gaseous halo and lived to tell the tale. But in the process, this dwarf galaxy, called the Large Magellanic Cloud (LMC), has been stripped of most of its own surrounding halo of gas. Researchers were surprised to find such an extremely small gaseous halo remaining — one around 10 times smaller than halos of other galaxies of similar mass. Still, the LMC has held onto enough of its gas to keep forming new stars. A smaller galaxy wouldn’t have survived such an encounter. This is the first time astronomers have been able to measure the size of the LMC’s halo — something they could do only with Hubble.

The Large Magellanic Cloud, also called the LMC, is one of the Milky Way galaxy’s nearest neighbours. This dwarf galaxy looms large in the southern nighttime sky at 20 times the apparent diameter of the full Moon.

Many researchers theorise that the LMC is not in orbit around our galaxy, but is just passing by. Those scientists think that the LMC has just completed its closest approach to the much more massive Milky Way. This passage has blown away most of the spherical halo of gas that surrounds the LMC.

The Department of Defense (DoD), alongside the Office of the Director of National Intelligence (ODNI), delivered its 2024 Annual Report on Unidentified Anomalous Phenomena (UAP) to Congress this week, fulfilling requirements outlined in the National Defense Authorization Act (NDAA) for Fiscal Year 2022, with amendments from the FY 2023 NDAA. The report, produced by the DoD’s All-Domain Anomaly Resolution Office (AARO), presents a comprehensive update on UAP sightings and analyses, covering incidents reported from May 2023 through June 2024.

According to the report, AARO received a total of 757 UAP reports during this period. Out of these, 485 incidents occurred within the last year, while the remaining 272 involved sightings from 2021 and 2022 that had not been previously cataloged. These new additions bring the total number of UAP cases reviewed by AARO to over 1,600 as of June 1, 2024.

The DoD emphasizes that UAP reports are critical to national security. Every incursion into designated air, sea, or space zones is taken seriously, with each sighting undergoing a systematic, data-driven analysis. AARO’s mandate includes examining these sightings for potential threats to service members, U.S. facilities, and sensitive operations.

Breast cancer is a major health concern worldwide, and early detection is crucial for effective treatment. Traditional imaging methods, such as mammography, have limitations, especially for women with dense breast tissue. Photoacoustic imaging, which combines light and sound to create detailed images of breast tissue, offers a promising alternative. However, recent research has highlighted a significant challenge: skin tone bias.

A team of researchers from Johns Hopkins University recently investigated how skin tone affects the visibility of breast cancer targets in photoacoustic imaging.

As reported in Biophotonics Discovery, the study focused on three image reconstruction methods: fast Fourier transform (FFT)-based reconstruction, delay-and-sum (DAS) beamforming, and short-lag spatial coherence (SLSC) beamforming. The study used simulations with different wavelengths (757800, and 1,064 nm), target sizes (0.5 to 3 mm), and skin tones (ranging from very light to dark).
