'Hidden galaxies': Key to unlocking some of universe's secrets
Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it would 'effectively break current models of galaxy numbers and evolution'. The possible galaxies may also provide the missing piece of the puzzle for the energy generation in the universe in infrared light. That's because their combined light would be enough to top-up the energy budget of the universe to the maximum we observe, effectively accounting for all remaining energy emission at these long wavelengths.
Ancient tools from a South African cave reveal connections between prehistoric people
In a cave overlooking the ocean on the southern coast of South Africa, archaeologists discovered thousands of stone tools, created by ancient humans roughly 20,000 years ago. By examining tiny details in the chipped edges of the blades and stones, archaeologists are able to tell how the tools were made -- which revealed that people were sharing crafting techniques over wide distances.
Certain nasal bacteria may boost the risk for COVID-19 infection, study finds
A new study has found that certain bacteria living in the nose may influence how likely someone is to get a COVID-19 infection. The research reveals that certain types of nasal bacteria can affect the levels of key proteins the virus needs to enter human cells, offering new insight into why some people are more vulnerable to COVID-19 than others.
