Science News! Let’s take a look at some of the important developments in science this week…
First, scientists entered the Bruniquel Cave in southern France, which had been sealed off for thousands of years, and found mysterious semicircles of stalagmites and evidence of fires that had been created by Neanderthals. Uranium dating shows the rings were stacked up 175,000 years ago, which makes them among the oldest structures created by our human relatives ever found. What the purpose of the structures was is still a mystery. Do you have a theory? Read more from the Smithsonian here.
Second, astronomers using the world’s most powerful telescope and a gravitational lensing technique were able to detect the faintest galaxy of the early universe yet found. The galaxy was born just after the Big Bang and appears to us as it was 13 Billion years ago. Read more from Phys.org here.
Third, the American military has reported the first instance of a bacteria resistant to colistin, a drug considered the last resort in killing superbugs. Although resistant to this last resort drug, the bacteria in this case was luckily not resistant to a class of drugs called carbapenems, and the patient who was carrying the bacteria is now well. However, if bacteria that are resistant to carbapenems are also able to acquire the resistance to colistin they may be unstoppable. Read more from the New York Times here.
