The first ever photograph of light as both a particle and wave

Posted by in categories: particle physics, quantum physics

(Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.

Quantum mechanics tells us that can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.

Meet Five Synthetic Biology Companies Using AI To Engineer Biology

Posted by in categories: bioengineering, biological, genetics, robotics/AI

TVs and radios blare that “artificial intelligence is coming,” and it will take your job and beat you at chess.

But AI is already here, and it can beat you — and the world’s best — at chess. In 2012, it was also used by Google to identify cats in YouTube videos. Today, it’s the reason Teslas have Autopilot and Netflix and Spotify seem to “read your mind.” Now, AI is changing the field of synthetic biology and how we engineer biology. It’s helping engineers design new ways to design genetic circuits — and it could leave a remarkable impact on the future of humanity through the huge investment it has been receiving ($12.3b in the last 10 years) and the markets it is disrupting.

World’s First 3D Printed Diamond Composite Was Created

Posted by in categories: 3D printing, materials

Anders Ohlsson Delivery Manager at Sandvik Additive Manufacturing, shared his excitement for the new process in the Sandvik press release stating, “On seeing its potential, we began to wonder what else would be possible from 3D-printing complex shapes in a material that is three times stiffer than steel, with heat conductivity higher than copper, the thermal expansion close to Invar – and with a density close to aluminum.”


Today we are taking a look at how Sandvik created the first-ever 3D printed diamond composite.

Positronic brain powered by Wikia

Posted by in category: robotics/AI

The positronic brain was an extremely sophisticated computation device capable of artificial sentience, created by Dr. Noonian Soong, based on an idea from author Isaac Asimov. ( TNG : “ Datalore ”)

This device consisted of an artificial neural network, designed to imitate the humanoid brain. The construction of a positronic brain was extremely complex, and Dr. Soong was the only scientist to have done so successfully – on at least six occasions: two unspecified prototypes, B-4, Lore, Data, and Juliana Soong (although the latter three were the only truly stable units).

One of the difficulties in creating a stable positronic brain was determining how the electron resistance across the neural filaments was to be resolved. ( TNG : ” The Measure Of A Man ”)

Graphene boosts microscope resolution by a factor of 10

Posted by in categories: biotech/medical, materials

Sub-nanometre resolution in 3D position measurements of light-emitting molecules has been achieved by physicists in Germany. Jörg Enderlein and colleagues at the University of Göttingen achieved the result by replacing metal films used in previous super-resolution techniques with single layers of graphene. Their innovation could allow researchers in a wide variety of fields to measure molecular positions to unprecedented degrees of accuracy.

Recently, the technique of single-molecule localization super-resolution microscopy (SMLM) has become an incredibly useful tool for researchers in fields ranging from fundamental physics to medical research. By analysing images of single light-emitting molecules, researchers can pinpoint the positions of their centres to within single atomic widths. However, SMLM faces one significant shortcoming: it can only locate molecules in 2D, giving no information about their positions along the out-of-plane axis.

This problem can be partially overcome through the technique of metal-induced energy transfer (MIET), which introduces a thin metal film to the setup. The idea is that the apparatus picks up changes in the molecule’s fluorescence that are caused by the molecule coupling to collective excitations of surface plasmons in the film. Since this light emission varies with distance from the film, researchers can use MIET to calculate the molecule’s distance relative to the film surface, allowing them to locate it along the third axis. Yet with current versions of the technique, the accuracy of this out-of-plane measurement is 3–5 times worse than that of lateral localization, in the plane of the film.

Real Artificial Gravity for SpaceX’s Starship

Posted by in categories: physics, space travel

Despite the many, many problems we face in the world today, it is still an exciting time to be alive! As we speak, mission planners and engineers are developing the concepts that will soon take astronauts on voyages beyond Low Earth Orbit (LEO) for the first time in almost fifty years. In addition to returning to the Moon, we are also looking further afield to Mars and other distant places in the Solar System.

This presents a number of challenges, not the least of which are the effects of prolonged exposure to radiation and microgravity. And whereas there are many viable options for protecting crews from radiation, gravity remains a bit of a stumbling block. To address this, Youtuber smallstars has proposed a concept that he calls the Gravity Link Starship (GLS), a variation of SpaceX’s Starship that will be able to provide its own artificial gravity.

Researchers build microscopic biohybrid robots propelled by muscles, nerves

Posted by in categories: bioengineering, robotics/AI

Researchers have developed soft robotic devices driven by neuromuscular tissue that triggers when stimulated by light—bringing mechanical engineering one step closer to developing autonomous biobots.

In 2014, research teams led by mechanical science and engineering professor Taher Saif and bioengineering professor Rashid Bashir at the University of Illinois worked together to developed the first self-propelled biohybrid swimming and walking biobots powered by beating derived from rats.

“Our first swimmer study successfully demonstrated that the bots, modeled after sperm cells, could in fact swim,” Saif said. “That generation of singled-tailed bots utilized cardiac tissue that beats on its own, but they could not sense the environment or make any decisions.”
