The Race for Antarctica's Lost Lakes
American, British and Russian exploration teams are racing to make first contact with long-lost lakes deep beneath Antarctica's ice in search of new life forms and climate change data.
What's the Latest Development?
American, British and Russian research teams are in three-way race to make first contact with long-lost lakes beneath Antarctica's icy surface. In search of new life forms that would have evolved in isolation, as well as climate change data, the teams will drill through ice sheets thousands of yards thick before lowering probes to collect samples of water and sediment. They will have to work quickly. Just 24 hours after drilling, water will rise through the hole and freeze again, as though no drilling had occurred at all.
What's the Big Idea?
Besides seeking new life forms, the explorers will collect data on the west Antarctic ice sheet. Glaciers in the ice sheet have been disappearing for years due to warming caused by global climate change. "If the sheet collapses, sea levels will rise at least 3 meters, and possibly as much as 5 meters, swamping low-lying areas worldwide." Sediments which the British team aim to collect should tell them when the ice sheet last collapsed. The longer ago it happened, the better; the more resilient the ice sheet, the less likely it is to collapse in the future.

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.
- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.
- Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury!
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
