Medical science has come a long way from tribal shaman dispensing herbs and roots. Having already cured many diseases and conditions that were once a death sentence, medical researchers continue to strive to help us live longer and healthier lives. Great advances are being made in regrowing damaged organs, turning back our biological clocks, and the big one – finding a cure for cancer.
Scientists are reporting success in using ultrasound to treat cognitive dysfunction in mice with simulated vascular dementia and Alzheimer's disease, which are the two most common forms of dementia. The ultrasound improved both the formation of blood vessels, and the regeneration of nerve cells.

As a lung infection, the most direct route to treat pneumonia would be inhalable drugs. Now researchers at Georgia Tech have made a step towards that goal, with breathable viruses that hunt down and kill disease-causing bacteria in the lungs.

Cancer cells have gone rogue and are dividing unchecked, and now Australian researchers have designed a new molecule that may put a stop to that. It targets a protein called PCNA, a donut-shaped structure that plays a key role in cell division, which could lead to a new class of cancer treatments.

Melanoma, a common type of skin cancer, is traditionally detected via observing changes in irregular moles, and then conducting a skin biopsy. A team has now developed a blood test that can detect melanoma in its early stages, reducing the need for expensive, and frequently unnecessary biopsies.

A fascinating cancer detection technique has been developed by scientists at Stanford University. The process involves a small magnetic wire being inserted into a vein where it attracts free-floating tumor cells in the blood.

Researchers at CNBP have developed a new targeted treatment for cancer. Chemotherapy drugs are wrapped in “nano-bubbles” called liposomes, which are then injected into the desired part of the body and made to release their payload on demand, by applying X-ray radiation.

The CRISPR gene editing revolution is less than a decade old and scientists are still learning how best to deploy this ground-breaking technique. A team has recently discovered why the technique sometimes fails, uncovering a novel insight that will hopefully make future research more efficient.

An emerging class of drugs called senolytics has been found to help restore the body to a more youthful state, and a new study has used a drug compound to extend the lifespan and improve the general health of older mice.

When a doctor prescribes a patient more than one drug they have no way to predict whether that combination will have an adverse side effect. A new system from Stanford University presents a novel solution – an AI-driven computer system than can predict the consequences of combining two drugs.

A promising new cancer drug delivery system has successfully passed early human safety trials. The treatment delivers cancer drugs in heat-activated capsules to tumors in the liver and then uses a focused ultrasound beam to remotely trigger the targeted release of their drug payload.
