Promising Plant Sciences Breakthrough Could Lead To Photosynthesis 2.0

  Promising Plant Sciences Breakthrough Could Lead To Photosynthesis 2.0 By solving a complex protein structure, biologists have unlocked a critical mechanism in plants that could lead to improvements in how photosynthesis works, and by consequence, greater crop yields. Photosynthesis is a brilliant invention of nature, but that’s not stopping scientists from trying to make it even better. New research published today in Nature describes how a team at the University of Sheffield has uncovered new insights into how an electrical chemical reaction in plants can significantly influence plant growth. The researchers are calling this mechanism the “beating heart” of photosynthesis.

Scientists have created the brightest light ever produced on the Earth, shining a billion times stronger than the surface of the sun. Normally an electron scatters just one photon of light at a time, but the light beam produced in the University of Want to discuss real- world problems, be involved in the

Scientists in Estonia and Finland have published the first research from their new facility within Sweden’s famous MAX IV x-ray laboratory.

In their new paper, they share tests on ionic liquids—think electrolytes on steroids—that were made possible by MAX IV’s brightest-in-the-world synchrotron beams.

The extremely bright light is cutting edge and approaches the speed of light, which shortens experiment duration and increases the fidelity of data and measurements.

A synchrotron is a kind of particle accelerator that uses the power of magnets (pictured above) to bend extremely bright beams in a circle. Where a cyclotron lets radiation bend further and further outward in a spiral, a synchrotron keeps the beam synced together in the same circular path, and each magnet bounces an individual beam off into a beamline. Brightness and speed accumulate together as electrons are pressed into traveling the circular path over and over. It’s easier to approach the speed of light when you have what feels like an infinite runway.

This creates an oscillating electric field (E) in the gap between each pair of electrodes, which exerts force on the particles when they pass through At speeds near the speed of light , the incremental velocity increase will be small, with the energy appearing as an increase in the mass of the particles.

Large accelerators are used for basic research in particle physics. The most powerful accelerator Thus elementary particle physicists tend to use machines creating beams of electrons , positrons Besides being of fundamental interest, electrons accelerated in the magnetic field causes the high

Synchrotron facilities like the one at MAX IV are also rare. There are only a handful of such facilities in the world. All are funded by governments or even by multiple governments in scientific coalitions. The newest planned synchrotron facility, Sirius, will be in Brazil. Sirius’s website presents synchrotron-enabled atomic and molecular studies as the future not just of science but of consumer and world health.

MAX IV is a synchrotron radiation facility within Sweden’s national laboratory, MAX-lab, where it’s the fourth successive synchrotron (MAX-I, II, and III) and by far the most powerful. The facility offers research space and time to a huge variety of projects, because radiation touches almost every kind of science in the 21st century.

How The 2010s Changed Physics Forever

NT Chief Minister Michael Gunner addresses the media in Darwin after Kumanjayi Walker, 19, was shot by a police officer who was trying to arrest him in his bedroom at Yuendumu on Saturday. Mr Gunner says it is his priority that the community of Yuendumu is supported through the healing process. "This is an incredibly sad time for all, a time of high emotion," he says. "What I ask for, right here, right now, is that everyone remain respectful and peaceful to each other. We cannot and will not let this divide us." (AAP VIDEO/Greg Roberts)

The Finnish-Estonian beamline, which is the term for the kinds of focused x-rays that teams at MAX IV are able to experiment with, opened in late 2018 after MAX IV’s first international collaboration. The technology that enables the beam is similar to other particle accelerators like at Fermilab, or the proton beam treatment for certain kinds of cancer.

The University of Tartu-sponsored research team studies ionic liquids, which are salts that stay liquid at or just above room temperature. Because of their chemical properties—salts are conductive and liquids are flexible and easy to work with—ionic liquids have strong potential in the field of supercapacitors. Some ionic liquids perform better than electrolytes in the same capacitor setup, but scientists don’t understand why that is.

Electrolytes enable transmission of electrical pulses within the human body and also make up the bulk of capacitors used in electrical applications. Electrolytes decompose (or separate) easily, but ionic liquids are much less understood, and they occur naturally in liquid form. To study the electronic makeup of ionic liquids, the Tartu researchers used their beamline to vaporize different ionic liquids and examine the results using their own metrics.

Thanks to the beamline's "intense photon flux," says Vambola Kisand, the head of the laboratory of x-ray spectroscopy at the UT Institute of Physics, the studies were "conducted with extremely good spectral resolution and short data acquisition times."

Sounds like Max IV has a very, very bright future ahead.

CERN's Oldest Particle Accelerator Is Still Running, 60 Years Later .
The oldest particle accelerator at CERN, home to the world’s most powerful particle accelerator, is celebrating its 60th birthday. It’s still running. The Proton Synchrotron (PS) accelerated its first protons on November 24, 1959. It was the world’s highest-energy accelerator when it first began running. Though it’s since lost the title but today supplies protons or heavy ions to a number of particle physics experiments, including the Large Hadron Collider (which currently holds the title as the largest and highest-energy accelerator).
