A vast reservoir of ancient water has been found thousands of feet under the ice in western Antarctica, scientists said in a paper published Thursday in the journal Science.
Researchers had long suspected but never before established the existence of such hidden pockets of Antarctic groundwater, which they believe act to lessen friction between ice sheets and underlying bedrock to make the ice more prone to slide from the continent’s interior toward the surrounding ocean.
Time will tell if more effective strategies can be developed to manage space junk in the future. But, as you are about to find out, we may not want to clear up space entirely.
Some of these “dead” spacecraft may still function!
1. Voyager 1 and 2 are still going strong.
Perhaps the most famous example of old spacecraft still in use today are Voyager 1 and 2. By far the farthest-traveled human-made objects ever sent into space, these amazing pieces of kit are still faithfully sending data back to Earth.
Scientists have given a fascinating new insight into the next steps to develop fast, energy-efficient, future computing systems that use light instead of electrons to process and store information—incorporating hardware inspired directly by the functioning of the human brain.
A team of scientists, including Professor C. David Wright from the University of Exeter, has explored the future potential for computer systems by using photonics in place of conventional electronics.
The article is published today (January 29th 2021) in the prestigious journal Nature Photonics.
Hearing loss is usually irreversible because there’s no way to grow back the necessary outer and inner ear sensory cells once they’ve been killed off. But we may have started on the path to change, thanks to new research in mice.
Scientists have discovered a single master gene that’s able to regulate whether ear hair cells into the outer or inner types required to restore hearing. That’s a significant step forward in being able to actually carry this out in the lab.
The master gene is called TBX2. Through experiments on mice, the team found that when it’s expressed, ear hair cells become inner hair cells; when it’s blocked, ear hair cells become outer hair cells. It’s a crucial toggle switch.

The Future is Wild is a series aired in 2002 (official website of the original show: https://www.thefutureiswild.com/) that explored how life could evolve in 3 different time scales: 5,100, and 200 million years into the future. presenting very different possible scenarios.
In these 20 years, some of these creatures would have a different look according to the current knowledge, although most changes are still pure speculation.
