Algae as vessels for synthetic biology

Posted by in categories: bioengineering, biological

Nice.


Algae (a term used to group many photosynthetic organisms into a rather heterologous mash-up) do not have a kind place in the public imagination. Take for example the following passage from Stephen King’s Pet Semetary:

“Dead fields under a November sky, scattered rose petals brown and turning up at the edges, empty pools scummed with algae, rot, decomposition, dust…”

The magic of the game changing electric dark matter black holes BH in the crowded centers of galaxies

Posted by in categories: cosmology, quantum physics

New electric dark matter black holes seem to be game changers if concentrated in galaxy centers.

Game changing because BH crowded areas do not form linear Herbig Haro systems with star formation in between.

Result: Red and Dead galaxies as the start of the decline and big crunch.

Quantum Entanglement: Slower Than Light

Posted by in categories: particle physics, quantum physics, space

Although this is true (speed of communication via entanglement is not at the speed of light); like other early stage technologies this will also evolve and improve in time.


China recently launched a satellite to test quantum entanglement in space. It’s an interesting experiment that could lead to “hack proof” satellite communication. It’s also led to a flurry of articles claiming that quantum entanglement allows particles to communicate faster than light. Several science bloggers have noted why this is wrong, but it’s worth emphasizing again. Quantum entanglement does not allow faster than light communication.

This particular misconception is grounded in the way quantum theory is typically popularized. Quantum objects can be both particles and waves, They have a wavefunction that describes the probability of certain outcomes, and when you measure the object it “collapses” into a particular particle state. Unfortunately this Copenhagen interpretation of quantum theory glosses over much of the subtlety of quantum behavior, so when it’s applied to entanglement it seems a bit contradictory.

Organic LEDs with low power consumption and long lifetimes

Posted by in categories: energy, mobile phones, quantum physics

A novel device architecture is used to simultaneously achieve extremely high internal quantum efficiencies, low drive voltages, and long lifetimes, at practical luminance levels.

An LED with an emissive organic thin film sandwiched between the anode and cathode is known as an organic-LED (OLED). The emission mechanism of an OLED is superficially similar to that of a standard LED, i.e., holes and electrons are injected from the anode and cathode, respectively, and these carriers recombine to form excited states (excitons) that lead to light emission.1 In recent years, smartphones and TVs with OLED displays have rapidly become widespread because OLEDs provide high contrast, a wide color gamut, light weight, thinness, and flexibility for the displays. OLEDs also have great potential for the creation of new lighting applications.2 The high power consumption and short lifetime of OLEDs, however, remain key issues.

New single-photon microwave source developed

Posted by in categories: computing, quantum physics

A collaboration including researchers at the National Physical Laboratory (NPL) has developed a tuneable, high-efficiency, single-photon microwave source. The technology has great potential for applications in quantum computing and quantum information technology, as well as in studying the fundamental reactions between light and matter in quantum circuits.

The tuneable microwave single-photon source

Circuits which produce single photons are a vital component in quantum computers. They usually consist of a quantum bit or ‘qubit’, coupled to a resonance circuit. The resonant circuit limits the photon output to specific frequencies depending on the design of the circuit.

ESO confirms the discovery of Earth’s closest potentially habitable neighbour

Posted by in categories: physics, space

Astronomers have today confirmed the existence of a planet orbiting the sun’s nearest neighbour, Proxima Centauri, which has the potential to host liquid water, and therefore life.

The exoplanet in question, Proxima b, is thought to be the Earth’s closest potentially habitable neighbour, making this discovery a major landmark in humanity’s exploration of the universe.
