Research has revealed the cluster of neurons that helps the brain’s internal GPS remember key landmarks. It is hoped that the findings will provide insight into a range of psychiatric disorders.

Dark energy is apparently even more mysterious than astronomers had thought.
Scientists first proposed the existence of this invisible force two decades ago, to explain the surprising discovery that the universe’s expansion is accelerating. (Surprising and incredibly important; the find netted three researchers the Nobel Prize in physics in 2011.)
The most-used astrophysical model of the universe’s structure and evolution regards dark energy as a constant. Indeed, many astronomers believe it to be the cosmological constant, which Einstein posited in 1917 as part of his theory of general relativity. [The History & Structure of the Universe in Pictures].

Building cracks and deterioration are common points of concern for asset owners and managers alike, but a new technology may soon alleviate these industry issues.
Researchers at the University of Cambridge are using micro-encapsulation technologies developed by Dolomite Microfluidics to develop self-healing construction materials.
The university’s Department of Engineering’s Geotechnical and Environmental Research Group said last month that it is developing microcapsules containing ‘healing’ agents such as minerals, epoxy, or polyurethane which can be added to building materials to allow the self-repair of small cracks that develop over time.

Smart building materials are altering the fabric of the housebuilding industry. Housebuilders are already looking ahead to the days when homes will fix themselves, serve their residents and tell us how we can build them better.
SMART CONCRETE
While housebuilders gaze into the future, researchers have been turning to the past for inspiration. Over the last few years, the DNA of concrete has been decoded and rewritten by scientists to make the material that built the Roman Empire fit for the future.

A new breed of algorithms has mastered Atari video games 10 times faster than state-of-the-art AI, with a breakthrough approach to problem solving.
Designing AI that can negotiate planning problems, especially those where rewards are not immediately obvious, is one of the most important research challenges in advancing the field.
A famous 2015 study showed Google DeepMind AI learnt to play Atari video games like Video Pinball to human level, but notoriously failed to learn a path to the first key in 1980s video game Montezuma’s Revenge due to the game’s complexity.

Experiencing a bacterial infection? You’re generally prescribed antibiotics by your doctor. But how exactly do those antibiotics and your white blood cells work in tandem to improve your infection?
“The human body’s first line of defense against bacteria are certain white blood cells called neutrophils,” says J. Scott VanEpps, M.D., Ph.D., assistant professor of emergency medicine at Michigan Medicine. “One of their weapons are neutrophil extracellular traps, also called NETs.”
The traps are microscopic networks of fibers made primarily of DNA that are produced by the neutrophils to capture bacteria. But how exactly they work, VanEpps notes, is still unclear.

Aubrey de Grey, Judy Campisi, Nir Barzilai in a panel titled “A Therapeutic Revolution Against Aging”. Hosted by John Lewis of Oisin.
This was an excellent panel! Topics included Yamanaka factors, epigenetic rollback, partial reprogramming and many more. Judy disagreed with Aubrey on the nature of aging, Nir brought up a great point about the secret to rejuvenation lying in uncovering just how a 50-year old egg cell becomes a new rejuvenated baby, and even a paper on Jeanne Calment was mentioned!
