Watch my “7 Signs of Longevity Revolution” keynote at Barclays

Longevity investor and visionary Sergey Young, founder of Longevity Vision Fund and Innovation Board Member of XPRIZE Foundation, delivers “7 Signs of Longevity Revolution” keynote at Barclay’s recent “Accelerating Evolution” conference, discussing recent developments in the longevity industry.

Watch to find out the forecasts for the industry’s trajectory of growth in the coming years, the increasing emergence of practical, real-world applications in the longevity sphere and how Longevity Vision Fund striving to be on the very forefront of the ongoing Longevity Revolution that is already happening around us today.

Bottomonium particles don’t go with the flow

A few millionths of a second after the Big Bang, the universe was so dense and hot that the quarks and gluons that make up protons, neutrons and other hadrons existed freely in what is known as the quark–gluon plasma. The ALICE experiment at the Large Hadron Collider (LHC) can recreate this plasma in high-energy collisions of beams of heavy ions of lead. However, ALICE, as well as any other collision experiments that can recreate the plasma, cannot observe this state of matter directly. The presence and properties of the plasma can only be deduced from the signatures it leaves on the particles that are produced in the collisions.

In a new article, presented at the ongoing European Physical Society conference on High-Energy Physics, the ALICE collaboration reports the first measurement of one such signature—the elliptic flow—for upsilon produced in lead–lead LHC collisions.

The upsilon is a bottomonium particle, consisting of a bottom (often also called beauty) quark and its antiquark. Bottomonia and their charm-quark counterparts, charmonium particles, are excellent probes of the quark–gluon . They are created in the initial stages of a heavy-ion collision and therefore experience the entire evolution of the plasma, from the moment it is produced to the moment it cools down and gives way to a state in which hadrons can form.

Russia Launches Telescope Into Space To Map The Cosmos In ‘Outstanding’ Detail

It would be the first-ever map of the universe in high-energy X-rays, Nature magazine noted.

Such a map “will be essential to solve the core questions of modern cosmology,” Roscosmos said in a press release. “How do dark energy and dark matter affect formation of the large-scale structure of the Universe? What is [the] cosmological evolution of supermassive black holes?”

The agency added that the telescope, which has reportedly taken decades to develop, is expected to find about “100,000 massive clusters of galaxies” and millions of supermassive black holes ― many of them new to science ― over a four-year survey period.

Fast new directed evolution technique makes viruses create drug proteins in days

Evolution is one of nature’s most impressive forces, allowing organisms to adapt to changing environments to survive. By harnessing and guiding that process scientists have managed to manipulate micro-organisms into producing useful new drugs and materials, but it’s still a time-consuming process. Now, researchers at the University of North Carolina (UNC) have developed a new tool that speeds up the process in mammalian cells, creating new therapeutics in a matter of days.

Neutral evolution shapes lifespan and aging

Different African killifish species vary extensively in their lifespans—from just a few months to several years. Scientists from the Max Planck Institute for Biology of Ageing in Cologne investigated how different lifespans have evolved in nature and discovered a fundamental mechanism by which detrimental mutations accumulate in the genome causing fish to age fast and become short-lived. In humans, mutations accumulate mainly in the genes that are active in old age.
