Researchers have developed a highly efficient new gene-editing method that uses virus-based protein fragments. The method could be used to level up existing cell and gene therapies used to treat cancer and other diseases.
-
One of the most profound mysteries facing science is how exactly life arose from non-living matter. Now, scientists have pinpointed a particular peptide that potentially kickstarted life – and it could all be nickelback’s fault.
-
Bacteria are fast developing resistance to our antibiotics, potentially ushering in a new “dark age of medicine” where basic infections become lethal again. Now scientists have developed self-assembling “nanonets” that can trap and kill superbugs.
-
In frontotemporal dementia and motor neuron disease, nerve cells are attacked and killed off, leading to the fast progression of the degenerative conditions. Now, a novel breakthrough might be able to stop this process without invasive surgery.
-
It's always good if the use of antibiotics can be avoided, to keep harmful bacteria from developing a resistance to them. A new wound-treatment spray could help, as it kills bacteria using peptides that occur naturally in our bodies.
-
Instead of injections or pills, why not engineer bacteria to secrete therapeutic molecules from within our gut? A new study is showing how a genetically modified probiotic can produce an anti-inflammatory molecule to treat rheumatoid arthritis in rats.
-
Researchers have demonstrated a new technique to fight cancer by attaching immunotherapy drugs to a molecule that seeks out the acidic environment of cancer cells. In tests in mice, a single dose was enough to eradicate even advanced tumors.
-
As many couples trying to conceive know, much can go wrong during that fateful meeting of sperm and egg. Now scientists have identified a new protein eggs use to draw in sperm, which could one day lead to new fertility treatments and contraceptives.
-
Melanoma is the deadliest form of skin cancer thanks to its ability to rapidly spread to other organs. Brazilian researchers have now developed a peptide that seems to slow the growth and spread of melanoma, improving the survival rates of test mice.
-
Spinal cord injuries are among the most debilitating. In a new breakthrough study, Northwestern University researchers have developed a gel containing “dancing molecules” that allowed paralyzed mice to walk again four weeks after a single injection.
-
Antibiotic-resistant bacteria are poised to become a major health threat in the coming decades – but new antibiotics may have been inside us all along. A search algorithm has discovered dozens of potential antimicrobial peptides in the human body.
-
Not only are surgical scars unsightly, but their limited elasticity can also reduce the patient's range of motion. There may be new hope, though, as a recent study has shed light on how a therapeutic peptide could drastically reduce such scarring.
