    A blood-thinning drug helped more stroke patients recover after clot removal

    After doctors pulled a blood clot from a stroke patient's brain, adding a drug called tirofiban helped more people return to living independently. In a trial of 1,380 people, 49% on the drug were independent after three months, versus 43% on a dummy treatment.

AI & Computer Science

  1. Credibility: Promising

    A tiny robot that folds from a hand into a walking humanoid

    Researchers built one small 27-joint robot whose parts rearrange to become either a five-fingered hand or a mini walking humanoid. The same hand fingers slide down to become the robot's legs and arms.

    A protein-folding AI may secretly hold clues about how proteins move, not just their final shape

    AlphaFold2 is a program that predicts a protein's folded shape. By gently blurring and shrinking the numbers inside it, a researcher pulled out a range of shapes that matched how one real protein bends and comes apart in physics simulations.

Physics & Space

  1. Credibility: Early

    Could dark matter slowly change its weight? A new idea explains an odd sign in the sky

    Physicists built a model where dark matter, the invisible stuff that outweighs stars, slowly changes its mass over billions of years. When tested against maps of the sky, this idea fit the real data a little better than today's standard picture of the universe.
  2. Credibility: Solid

    A telescope the size of Earth sees a black hole's jet twisting near its source

    Astronomers made the sharpest-ever picture of the gas beam shooting from a giant black hole in the galaxy 3C 279. The innermost part of the beam is bent almost sideways from the rest and points nearly straight at Earth, and this twist keeps showing up over ten years.

    A specific carbon molecule may explain a faint glow James Webb sees in space

    Scientists think a molecule called hexahydropyrene creates part of a faint infrared glow seen in a star-forming cloud. They measured its light fingerprint in the lab and matched it to what the James Webb Space Telescope sees.
  4. Credibility: Promising

    A bumpy surface might make sliding smoother, not rougher, a physics study hints

    Scientists found that when the squeezing force between two crystal surfaces is strongest in the middle and fades to zero at the edges, the surfaces can slide with even less friction. They showed this with mathematics and computer simulations of tiny sliding chains.

    People with low or unstable incomes may face higher odds of a rare, severe pain disease

    In South Korea, adults with the lowest incomes were more likely to develop a rare chronic pain condition than the richest. Those in the lowest income group had about 3.7 times the risk over 10 years.
