    Fossils reveal a massive shark that ruled Australia in dinosaur times
    22/11/25 11:08:49
    Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks were experimenting with gigantic sizes far earlier than scientists believed, competing with the marine “monsters” of the dinosaur age.
    Rapid fault healing could rewrite earthquake physics
    22/11/25 08:37:56
    Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the fault quickly regains strength. Lab experiments show that mineral grains can weld together under intense heat and pressure, acting like a natural glue. This rapid cohesion may be a missing factor in earthquake modeling.
    Just a few cigarettes a day can damage your heart for decades
    22/11/25 06:19:55
    People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see their risk of heart failure climb sharply. While quitting leads to major health improvements, some risk remains for decades. The safest approach is quitting entirely, especially at younger ages.
    New evidence shows tirzepatide and semaglutide strongly protect the heart
    22/11/25 05:10:04
    A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection—reducing heart attack, stroke, and death in adults with type 2 diabetes. While companies have claimed large differences favoring their own medications, researchers found only modest distinctions between the two blockbuster GLP-1 drugs.
    Scientists reveal a hidden hormone switch for learning
    22/11/25 05:32:51
    Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain how hormonal cycles influence cognitive performance and psychiatric symptoms. This connection offers a new path for understanding brain disorders tied to dopamine.
