Life’s chemistry may begin in the cold darkness of space
New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. Scientists found that simple amino acids bond into peptides on interstellar dust, long before stars and planets exist. This challenges the idea that complex life chemistry only happens on planets. It also boosts the odds that life-friendly ingredients are widespread across the universe.

This tiny peptide could help stop brain damage after injury
A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, calming inflammation and reducing cell death while improving recovery. The peptide worked in both mice and pigs, whose brains are closer to humans in structure. Researchers are now preparing to move toward early human clinical trials.
