The sound of astrophysics <♥> "If you stretch them (the waveform models) out, you get other waves inside them. [...] You can get the computer to just track the shape of the waveform—and that's how I was getting all the piano melodies,"

Come on out, exotic matter, don't be shy! Let's ride a TARDIS with the Doctor! <♥>

New research shows that time travel is mathematically possible _ "Physicists have developed a new mathematical model that shows how time travel is theoretically possible. They used Einstein's Theory of General Relativity as a springboard for their hypothetical device, which they call a Traversable Acausal Retrograde Domain in Space-time (TARDIS)."

These radical thoughts are a disease! Who has infected you? (...) Again with this woman?! Did I not warned you that she was dangerous? (...) You are a very clever boy Einstein... very clever. But you have one fault: you will never let yourself be told anything. - Weber to Einstein about Mileva Maric

The ‘AgIC’ pens make it possible for people to draw ink that conducts electricity on paper as it runs through circuits. To illustrate the properties of its pen, Kandenko created pop-up paper houses that are illuminated by the pen and posters in traditional Japanese patterns that also feature elements that have been created from the ink. These pens have the potential to bring architectural paper models and children’s storybooks to life like never before. The electronic pens from Kandenko simplify the process of building circuits into an easy and intuitive process that requires little to no experience—just a steady drawing hand.

Zhenan Bao, a professor of chemical engineering at Stanford, has spent a decade trying to develop a material that mimics skin’s ability to flex and heal, while also serving as the sensor net that sends touch, temperature and pain signals to the brain. Ultimately she wants to create a flexible electronic fabric embedded with sensors that could cover a prosthetic limb and replicate some of skin’s sensory functions.

Bao’s work, reported today in Science, takes another step toward her goal by replicating one aspect of touch, the sensory mechanism that enables us to distinguish the pressure difference between a limp handshake and a firm grip.

“This is the first time a flexible, skin-like material has been able to detect pressure and also transmit a signal to a component of the nervous system,” said Bao, who led the 17-person research team responsible for the achievement.

Using the Bridge Inspector HoloLens app created by the Cambridge team, engineers are able to inspect the condition of infrastructure in office as if they were standing on site in front of the real asset. "Bringing a bridge to life at full scale while still being aware of your surroundings is a major time saver for experienced inspectors," explains Dr Ioannis Brilakis.

In the study, the research team reported that red-light absorbing carbon nitride (C₃N₄) sheets lead to remarkable proliferation and osteogenic differentiation by runt-related transcription factor 2 (Runx2) activation, a key transcription factor associated with osteoblast differentiation. (...)

Professor Kim and Professor Suh examined the C₃N₄sheets. They discovered that this material absorbs red light and then emits fluorescence, which can be used to speed up bone regeneration. Professor Kim's team synthesized carbon nitrogen derivatives from melamine compounds. Then, they analyzed the light-absorbing characteristics of C₃N₄sheets at a wavelength range of 455-635 nanometers (nm). As a result, the C₃N₄sheets were found to emit fluorescence at the wavelength of 635 nm when exposed to red light in a liquid state. At this time, the released electrons induced calcium to accumulate in the cytoplasm.

Professor Suh conducted a biomedical application of this material. First, stem cells and cancer cells were cultured in a medium containing 200 μg/ml of C₃N₄sheets. After two days of testing, the material showed no cytotoxicity, making it useful as biomaterials.It was also confirmed that C₃N₄sheets act on stem cells to differentiate into osteoblasts to promote mineral formation. In this process, the osteogenic differentiation marker genes (ALP, BSP, and OCN) proliferated. Moreover, the Rux2 (Runt-related transcription factor 2), a key factor in osteoblast differentiation was also activated. This resulted in the increased osteoblast differentiation and accelerated bone formation.

The droids eat algae through a polymer membrane mouthpiece. Algae-filled water goes into the robot’s ‘stomach’ that includes a microbic fuel cell. The bacteria dissolves the organic food, and that gives the bot energy. The robot then excretes waste through a canal in the back. The robot can also “die” and decompose away.

“This is exciting as all subjects accomplished the tasks using a completely noninvasive technique. We see a big potential for this research to help people who are paralyzed or have neurodegenerative diseases to become more independent without a need for surgical implants.”

Places where precision is required often uses industrial automation. These include hazardous environments, heavy lifting or repetitive production. But more often than not, the robotics are working alongside humans on factories’ production lines. However, they come with the risk of injury as the robot will continue along its path no matter the obstruction. (...)

The robot can perform a variety of tasks. These tasks include positioning, drilling, assembling and any automated job that requires some form of dexterity. The Franka Emika uses strain gauges to measure the forces on its motors, which classifies the Franka as a torque-controlled robot. It can not only detect minor collisions but also halt the action to prevent any damage and continue once the path is clear.

“The extremely flexible mesh, made of gold wires sandwiched between layers of a polymer, easily coils into a needle so it can be injected rather than implanted, avoiding a more extensive surgery. Part of the mesh sticks out though the brain and a hole in the skull so that it can be wired up to a computer that controls the electric jolts and measures the neurons’ activity. But eventually, Lieber says, the controls and power supply could be implanted in the body, as they are in today’s systems for deep brain stimulation. “
