Scheduled for first light in the 2020s, a powerful new class of giant telescopes will study the Universe in more detail than ever before — as long as their adaptive optics systems can sharpen their view. ESO’s Laser Systems group is currently undertaking field tests with a specialised laser at the Observatorio del Roque de los Muchachos, at La Palma on the Canary Islands. One of their goals is to make laser guide stars even brighter for large and extremely large telescopes, such as ESO’s ELT and the Giant Magellan Telescope. To find out more, we spoke to Domenico Bonaccini Calia, a physicist from ESO’s Laser Systems Department with over 20 years of experience.

Older people can still grow new brain cells like young people, new study shows. Reference: surg.ws/2GYVXOU

Researchers show for the first time that healthy older men and women can generate just as many new brain cells as younger people.

We all know about the double helix structure of DNA, but researchers have described a type of DNA that’s never been observed in a living cell: i-motif DNA. This knot-shaped DNA uses nucleotides differently than helical DNA, and scientists suspect it plays a regulatory role in the cell.

Today we will be discussing new research published in nature where researchers modified a protein associated with Alzheimer’s disease into a more harmless form, allowing them to remove the damage caused by Alzheimer’s in human cells. This is especially important because the research was not conducted on mice but rather human cells, and shows a potential way to halt the formation of the plaques associated with Alzheimer’s in the first place.

Some time ago, we discussed the matter of beauty in the context of life extension; in particular, we tried to dispel the belief that the motivation behind life extension might be simply vanity. The article argued that there is nothing wrong with wanting to preserve youthful looks and attempted to explain the evolutionary reasons for our perception of beauty, but it did not discuss a perhaps even more important fact: aesthetics are not the main problem of elderly looks. The main problem, as it always is with age-related decay, is a decline in health and functionality.

What do elderly people look like?

If I ask you to imagine an old person, you’re likely to imagine somebody with grey hair, slack, wrinkled skin, and weak and flaccid muscles. While these features may vary from person to person, this is an accurate enough description of anyone past the age of 70, and it generally gets worse and worse as aging progresses. Exercise might help improve your physical condition, and perhaps a good facial cream might make you look slightly younger than your chronological age, but, after a certain point, the signs of age-related decay are unmistakable and irreversible.
