Physicists have discovered that changes in the Earth’s ozone layer due to climate change will reduce the amount of ultraviolet radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. Other regions of the Earth, such as the tropics and Antarctica, will instead face increasing levels of UV radiation.

Scientists have developed a prototype of an electrocardiogram or ECG necklace. The technology enables long-term monitoring of cardiac performance and allows patients to remain ambulatory and continue their routine daily activities while under observation. The embedded beat detection algorithm copes with the artefacts inherent to ambulatory monitoring systems.

Less than two months after they inaugurated the world’s largest telescope, astronomers have used one of the world’s most advanced telescopic instruments to gather images of the heavens. The handful of “first light” images include a yellow and blue orb-like structure that depicts our Milky Way galaxy, home to thousands of black holes — including, [...]

In tumors formed by human breast cancer cells in mice, a diabetes drug was more effective than chemotherapy alone in prolonging remission. Mice appeared tumor-free for the two months after treatment before the end of the experiment. The drug, metformin, appears to selectively kill cancer stem cells in culture dishes and in mice.
