    Scientists find a massive hidden CO2 sponge beneath the ocean floor
    11/12/25 18:42:22
    Researchers found that eroded lava rubble beneath the South Atlantic can trap enormous amounts of CO2 for tens of millions of years. These porous breccia deposits store far more carbon than previously sampled ocean crust. The discovery reshapes how scientists view the long-term balance of carbon between the ocean, rocks, and atmosphere. It also reveals a hidden mechanism that helps stabilize Earth’s climate over geological timescales.
    Stressed rats keep returning to cannabis and scientists know why
    11/12/25 18:15:09
    Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility and low endocannabinoid levels also contributed to increased use. The results hint at possible early indicators of vulnerability to drug misuse.
    Even moderate drinking carries a bigger cancer risk than you think
    11/12/25 17:33:33
    Researchers found that both how often and how much someone drinks significantly shape their cancer risk, even at moderate levels. Vulnerability varies across groups, with genetics, socioeconomic status, obesity, and lifestyle behaviors amplifying harm. The review also uncovered gender differences, beverage-specific risks, and biological pathways that intensify cancer development.
    Gene-edited CAR-T cells erase aggressive T-cell leukemia
    11/12/25 10:14:40
    A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely rewriting tiny sections of DNA, scientists at UCL and Great Ormond Street Hospital created universal CAR T-cells capable of targeting the cancer without harming themselves—a long-standing challenge in T-cell–based therapies. Early trial results show deep, long-lasting remissions, including in patients who had exhausted standard treatment options.
    New research reveals how everyday cues secretly shape your habits
    11/12/25 04:41:05
    Researchers uncovered how shifting levels of a brain protein called KCC2 can reshape the way cues become linked with rewards, sometimes making habits form more quickly or more powerfully than expected. When this protein drops, dopamine neurons fire more intensely, strengthening new associations in ways that resemble how addictive behaviors take hold. Rat studies showed that even brief, synchronized bursts of neural activity can amplify reward learning, offering insight into why everyday triggers, like a morning routine, can provoke strong cravings.
