15,000-year-old site in Mexico reveals human-made 'mammoth traps'
Researchers have long believed that during the hunter-gatherer phase, humans were not very willing to hunt mammoths, giant elephant-like mammals, except in very special circumstances. But a discovery at Tultepec, north of Mexico City, has revealed human-made pits containing the bones of at least 14 mammoths. The pits were 1.7m deep and 25m wide, with perpendicular walls to prevent escape, suggesting humans may have hunted mammoths much more actively.

Urea could help make concrete on moon
The European Space Agency said researchers in a recent study it sponsored found that urea, the main organic compound in urine, would make the mixture for a “lunar concrete” more malleable before it hardens into its sturdy final form. “The hope is that astronaut urine could be essentially used as it is on a future lunar base, with minor adjustments to the water content,” study co-author Marlies Arnhof said

Coronavirus vaccine begins pre-clinical trials in Australia
Australia's national science agency has begun pre-clinical trials to find a vaccine for the deadly coronavirus. This stage will likely take three months and experts say the vaccine will probably not be ready until late next year. Although the process is going much faster than usual, it is unlikely that the vaccine will be available this year.

Australian researchers move one step closer to coronavirus vaccine
Australian researchers have said that they have managed to map the immune system's response to the coronavirus and that it is remarkably similar to the flu. This has allowed them to find what the immune system is lacking to properly fend off the virus. They are now one step closer to a vaccine.
