The 2024 #NobelPrize in Physiology or Medicine focuses on the discovery of a vital regulatory mechanism used in cells to control gene activity. Genetic information flows from DNA to messenger RNA (mRNA), via a process called transcription, and then on to the cellular machinery for protein production. There, mRNAs are translated so that proteins are made according to the genetic instructions stored in DNA. Since the mid-20th century, several of the most fundamental scientific discoveries have explained how these processes work. In 1993, this year's Nobel Prize laureates published unexpected findings describing a new level of gene regulation, which turned out to be highly significant and conserved throughout evolution. They discovered microRNA, a new class of tiny RNA molecules that play a crucial role in gene regulation. Read more: bit.ly/4dlPE6f

The retina is arguably the most impressive part of the brain. It’s the only part of the brain that faces the world directly - it’s a sensor and processor in one Its consumes 50% more energy per gram than the rest of the brain. 1000:1 compression from retina to optic nerve 25000:1 from optic nerve to brain For every 1Gb collected by the retina, 1Mb is sent to the brain thru the optic nerve and < 100bits used, at a rate of about 875Kbps. Similar to broadband internet.

Mathematician Terrence Tao (currently 48 y/o) is the youngest person to be promoted to full professor at UCLA, at the age of 24. He also holds the James and Carol Collins chair, which is one of the highest honors in the UCLA faculty. He was a child prodigy who started learning calculus at the age of seven and competed in the International Mathematical Olympiad at the age of ten, winning a bronze, silver, and gold medal in three consecutive years. He has won numerous prestigious awards, including the Fields Medal, the MacArthur Fellowship, the Breakthrough Prize in Mathematics, the Royal Medal, and the Grande Médaille. He is also a Fellow of the Australian Academy of Science and the Royal Society. He has written or co-authored over 300 research papers, covering a wide range of topics such as harmonic analysis, partial differential equations, combinatorics, number theory, and more. He is also an editor or associate editor of several mathematical journals.
