Researchers think genetically engineered versions of microbes that can live in humans could help treat some rare genetic disorders and perhaps help with Type 1 diabetes, cirrhosis and cancer.
Getting DNA into plant cells is tricky. Researchers have tried using infectious bacteria, as well as gene guns that shoot gold bullets. Then a physicist came up with a new approach almost by accident.
British doctors report the apparent eradication of HIV from a patient who was undergoing treatment for cancer. It’s only the second time this has been accomplished, despite many attempts.
Researchers are learning that attitude can have measurable effects on health. For a food allergy therapy, thinking of stressful side effects as positive signals helped patients complete the treatment.
Most patients do fine, research suggests, when the lead surgeon steps away to begin another procedure. But patients who are older or have underlying medical conditions sometimes fare worse.
The insects were created, using CRISPR, to carry a powerful “gene drive.” The mosquitoes could provide a potent weapon against malaria, but they raise fears about unpredictable environmental effects.
NASA’s six-wheeled rover landed on the red planet in January 2004 for what was billed as a 90-day mission. The plucky robot was still going until a dust storm on Mars last summer killed it.
Researchers say the metabolism of a woman’s brain remains higher than a man’s throughout a lifetime. And that may help with late-life creativity and learning.
A lot of vaccines and some medications need to be delivered by injection. Two groups of researchers are designing ways of delivering these medications by putting them in pill form.
The last five years are also the five hottest years on record for average global temperature, according to scientists from NASA and the National Oceanic and Atmospheric Administration.
