Scientists at a Russian university have developed a unique metal-vapor laser, which can cut through bones, tissue or glass without burning or damaging them. They say the technology could be used in a wide range of fields – from medicine to smartphones.
Medical marijuana pills do not help relieve dementia symptoms any better than placebo treatment, researchers in the Netherlands have found, refusing however to draw any conclusions on the drug’s effectiveness until higher doses are tested.
Australian scientists have for the first time developed an electronic long-term memory cell that mimics the work of a human brain. Researchers say the discovery is a step towards creating a bionic brain.
A deadly typhoid ‘superbug’ is spreading across Africa and Asia, creating a “previously under-appreciated and ongoing epidemic,” a groundbreaking international study warns. H58, driven by a single family of the bacteria, is resistant to most antibiotics.
A new technique is enabling a patient’s lung to keep breathing for up to a day outside their body. Doctors are hailing it as a success that could see the number of transplants in a year double and allow them to save hundreds more lives.
British scientists have discovered that a series of rapid frosts and thaws could have been a “vital spark” for life to originate on Earth. They now believe that living cells naturally evolved from a biochemical soup at the early days of our planet.
Finishing each dinner with a glass of red wine might to be a good idea for people with diabetes, Israeli researchers claim. The drink appears to boost levels of “good cholesterol,” thus helping to contain the disease.
American scientists have discovered that cosmic hotspots near dying stars are prime locations for forming molecular precursors to DNA. They claim life originated not just in space but also near the incredibly hot dying stars.
Scientists have discovered a novel kind of stem cell that could one day generate cells and tissues for any kind of organ in the human body – a development that may potentially help the 30 Americans who die every day due to a shortage of organ donors.
