Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher’s discovery, other scientists—notably, Phoebus Levene and Erwin Chargaff—carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix.

ESO’s Very Large Telescope (VLT) at Paranal Observatory, Chile, is the world’s most advanced optical instrument. The VLT uses state-of-the-art technology to provide the sharpest possible images, including adaptive optics with the laser guide stars shown in this image. The VLT uses these lasers to measure the turbulence in the Earth’s atmosphere, and responds by changing the shape of a mirror to counteract the negative effects of this turbulence.

Tesla is apparently significantly ramping up its effort to help rebuild the power grid in Puerto Rico after it was destroyed by hurricanes last year.

After having completed hundreds of energy storage project on the islands in the last few months, Tesla CEO Elon Musk now says that they have ‘about 11,000’ energy storage projects underway in Puerto Rico, which means something big is in the work.

LunaDNA and Nebula Genomics are offering incentives in hopes of getting consumers to share their data with scientific “bio-banks”.

There is no doubt that artificial general intelligence (AGI) — an AI that is capable of generating human-level intelligence — is on its way. It’s only a matter a when, not if. According to some researchers, the quest to developing AGI may take longer than expected. But even then, the quest continues on.

How we treat robots in the future may significantly rely on how we expose children to artificially intelligent supertoys today.

This NASA/ESA Hubble Space Telescope image shows a cluster of hundreds of galaxies located about 7.5 billion light-years from Earth. The brightest galaxy within this cluster, named SDSS J1156+1911, is visible in the lower middle of the frame. It was discovered by the Sloan Giant Arcs Survey, which studied data maps covering huge parts of the sky from the Sloan Digital Sky Survey. The survey found more than 70 galaxies that look to be significantly affected by a cosmic phenomenon known as gravitational lensing.

Gravitational lensing is one of the predictions of Albert Einstein’s General Theory of Relativity. The mass contained within a galaxy is so immense that it can actually warp and bend the very fabric of its surroundings (known as space-time), forcing light to travel along curved paths. As a result, the image of a more distant galaxy appears distorted and amplified to an observer, as the light from it has been bent around the intervening galaxy. This effect can be very useful in astronomy, allowing astronomers to see galaxies that are either obscured or too distant to be otherwise detected by our current instruments.

Galaxy clusters are giant structures containing hundreds to thousands of galaxies, some with masses over one million billion times the mass of the Sun! SDSS J1156+1911 is only roughly 600 billion times the mass of the Sun, making it less massive than the average galaxy. However, it is massive enough to produce the fuzzy, greenish streak seen just below the brightest galaxy — the lensed image of a more distant galaxy.

Current state of the art in-space propulsion systems based on chemical or ion propellants fail to meet requirements of 21st century space missions. Antimatter is a candidate mechanism for a propulsion system that could transport humans and/or robotic systems with drastically reduced transit times, providing quicker scientific results, increasing the payload mass to allow more capable instruments and larger crews, and reducing the overall mission cost. Unfortunately, previous propulsion concepts relied on unrealistic amounts of trapped antimatter — orders of magnitude away from any near-term capability. The goal of this effort is to determine the feasibility of a (TRL 1–2) radioisotope positron catalyzed fusion propulsion concept that does not rely on trapped antimatter. Such a transformative technology inspires and drives further innovation within the aerospace community and can be applied to a relevant mission — the bulk retrieval of an entire asteroid into translunar space — a mission of great scientific and commercial interest (e.g. asteroid mining). The idea of harnessing resources from asteroids goes back more than a century to Tsiolkovsky. Fundamentally, for asteroid mining to become financially viable, the cost of the retrieval spacecraft must be less than the value gained from the asteroid. Therefore, developing technology (e.g. efficient propulsion systems) that decreases the mass and complexity of the retrieval spacecraft must be a priority.

That’s how long it will take to produce and launch a rocket if the parts are 3D printed, according to the CEO of Relativity Space, a startup that seeks to do just that.
