Algorithms have helped uncover a new antibiotic that shows promise against some nasty bacteria, using a novel mode of attack that should be hard for them to develop resistance to. Most importantly it could unlock a whole new arsenal of antibiotics.

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.

Cataracts are one of the most common forms of vision impairment, and unfortunately surgery is the only real treatment. But the clouds may be parting on a new drug treatment, improving the vision of the majority of mice it was tested on.

Preliminary data from a large Phase 3 clinical trial is offering promising signs for a new anti-obesity drug. Called tirzepatide, the drug helped overweight and obese participants lose up to 22.5 percent of their total body weight over 72 weeks.

New research has found genetically engineered bacteria may be an effective Parkinson’s disease treatment. Scientists engineered a bacteria to synthesize a consistent source of medicine inside a patient’s gut, and animal tests have shown it is effective.

Scientists have found that an existing drug, already used in humans, could help restore vision lost to conditions like age-related macular degeneration and retinitis pigmentosa. The discovery could also lead to a whole new class of drugs.

Treatments like chemo and immunotherapy haven't been very effective against pancreatic cancer. In a new mouse study, scientists have found that blocking an inflammatory pathway helps make this deadly cancer vulnerable to these therapies.

A study has reported the results of the first modern clinical investigation to compare the acute effects of psychedelics LSD and psilocybin. The study reveals little subjective difference between the two drugs beyond LSD lasting longer than psilocybin.

Antibiotic-resistant bacteria are poised to become a major health problem, predicted to claim up to 10 million lives a year by 2050. Researchers have found a new way to fight back, by targeting a protein that bacteria use to generate drug resistance.

A wide-ranging study into pharmaceutical pollution of the world's rivers has found that more than a quarter of those studied carry potentially toxic levels of drugs, with such pollution touching every continent on Earth.

Delta-8 THC is similar to its commonly known psychoactive cousin, delta-9 THC, and new studies are offering the first large-scale insights into what kinds of effects people are experiencing with this unique and under-researched drug.

Animals like axolotls can regrow fully functional replacements for lost limbs. In a breakthrough new study, scientists have demonstrated how one dose of a drug cocktail can regrow lost limbs in frogs that don’t normally have regenerative abilities.
