    UT Arlington physics professor unveils latest picklock to the brain

    A UT Arlington assistant physics professor has published a paper about a new fiber-optic tool that would make it possible to show how neighboring regions of the brain react to stimulation. Dr. Samarendra Mohanty and his team — who have a knack for fiber-optics — wrote in the journal Optics Letters about the development of a “fiber-optic, two-photon, optogenetic stimulator and its use on human cells in a laboratory.”

     

    In more layman’s terms, this tiny tool, which is more precise and safer than previous methods, would be helpful in understanding how the brain interacts with itself when stimulated.

     
     

      The tiny, fiber-optic tool would be helpful in understanding how the brain interacts with itself when stimulated.

     

     

    The two-photon optogenetic stimulator works by introducing the gene for a light-responding protein called ChR2 into a cluster of cells, which are then excited with a fiber-optic infrared beam. Researchers examine the response in the cluster, as well as any other parts of the brain that change with the stimulation.

     

    Because of its use of infrared light, the stimulator does not cause the damage associated with traditional electric pulses used in current and past research. Infrared light also is more precise because it requires less energy than other optogenetic stimulators higher up on the electromagnetic spectrum, like blue or green.

     

    Mohanty’s use of fiber-optics gives his team more precision than previous microscopes and scanners.

     

    Last month, President Obama announced the BRAIN initiative — short for Brain Research through Advancing Innovative Neurotechnologies — an effort to “map the brain” to combat conditions like stroke, autism and Alzheimer’s. BRAIN would supply $100 million to research to help scientists better understand how we think, learn and remember.

     

    Dr. Mohanty’s stimulator could help progress exploration within the initiative.

    Texas ranks as No. 1 state with the most people in financial distress

    Texans are stretched thin financially.

    Experiencing financial strife is a nightmare of many Americans, but it appears to be a looming reality for Texans, according to a just-released WalletHub study ranking Texas the No. 1 most financially distressed state in America.

    To determine the states with the most financially distressed residents, WalletHub compared all 50 states across nine metrics in six major categories, such as average credit scores, the share of people with "accounts in distress" (meaning an account that's in forbearance or has deferred payments), the one-year change in bankruptcy filings from March 2024, and search interest indexes for "debt" and "loans."

    Joining Texas among the top five most distressed states are Florida (No. 2), Louisiana (No. 3), Nevada (No. 4), and South Carolina (No. 5).

    Texas' new ranking as the most financially distressed state in 2025 may be unexpected, WalletHub says, considering the state has a "bigger GDP than most countries" and still has one of the top 10 best economies in the nation (even though that ranking is also lower than it was in previous years).

    Even so, Texas residents are stretching themselves very thin financially this year. Texans had the ninth lowest average credit scores nationwide during the first quarter of 2025, the study found, and Texans had the sixth-highest increase in non-business-related bankruptcy filings over the last year, toppling 22 percent.

    "Texas also had the third-highest number of accounts in forbearance or with deferred payments per person, and the seventh-highest share of people with these distressed accounts, at 7.1 percent," the report said.

    This is where Texas ranked across the study's six key dimensions, where No. 1 means "most distressed:"

    • No. 5 – "Loans" search interest index rank
    • No. 6 – Change in bankruptcy filings from March 2024 to March 2025 rank
    • No. 7 – Average number of accounts in distress rank
    • No. 8 – People with accounts in distress rank
    • No. 13 – Credit score rank and “debt” search interest index rank
    The study also clarified that the state's high search rates for "debt" and "loans" is a key indication that Texans are "desperate to borrow, despite already owing money."
    Examining these financial factors on the state level is important for understanding how Americans are faring with economic issues like inflation, unemployment rates, or natural disasters, according to WalletHub analyst Chip Lupo.
    "When you combine data about people delaying payments with other metrics like bankruptcy filings and credit score changes, it paints a good picture of the overall economic trends of a state," Lupo said.

    At least inflation isn't impacting Dallas as much as other U.S. cities.

    On the other side of the spectrum, states like Hawaii (No. 50), Vermont (No. 49), and Alaska (No. 48) are the least financially distressed states in America.

    The top 10 states with the most people in financial distress in 2025 are:

    • No. 1 – Texas
    • No. 2 – Florida
    • No. 3 – Louisiana
    • No. 4 – Nevada
    • No. 5 – South Carolina
    • No. 6 – Oklahoma
    • No. 7 – North Carolina
    • No. 8 – Mississippi
    • No. 9 – Kentucky
    • No. 10 – Alabama
