The southern Red Sea is more readily connected with the Indian Ocean than with the northern Red Sea, according to simulations carried out at KAUST. This helps explain genetic patterns seen in the Red Sea and highlights the need for a collaborative regional approach to marine conservation.
Graphene is often seen as the wonder material of the future. Scientists can now grow perfect graphene layers on square centimetre-sized crystals. A research team from the University of Göttingen, together with the Chemnitz University of Technology and the Physikalisch-Technische Bundesanstalt Braunschweig, has investigated the influence of the underlying crystal on the electrical resistance of graphene. Contrary to previous assumptions, the new results show that the process known as the 'proximity effect' varies considerably at a nanometre scale.
WEST LAFAYETTE, Ind. - Nickel is a widely used metal in the manufacturing industry for both industrial and advanced material processes. Now, Purdue University innovators have created a hybrid technique to fabricate a new form of nickel that may help the future production of lifesaving medical devices, high-tech devices and vehicles with strong corrosion-resistant protection.
The Purdue technique involves a process where high-yield electrodeposition is applied on certain conductive substrates. The Purdue team's work is published in the December edition of Nanoscale.
Clicks, squeaks, chirps, and buzzes...though they may be difficult to distinguish to our ears, such sounds are used by echolocating animals to paint a vivid picture of their surroundings. By generating a sound and then listening to how the sound waves bounce off of objects around them, these animals are able to "see" using sound. While a number of species engage in some form of echolocation, including some birds, shrews, and even humans, the echolocation systems of bats and toothed whales (including dolphins, porpoises, killer whales, and sperm whales) are exquisitely sophisticated.
The operation of components for future computers can now be filmed in HD quality, so to speak. Manish Garg and Klaus Kern, researchers at the Max Planck Institute for Solid State Research in Stuttgart, have developed a microscope for the extremely fast processes that take place on the quantum scale. This microscope - a sort of HD camera for the quantum world - allows the precise tracking of electron movements down to the individual atom. It should therefore provide useful insights when it comes to developing extremely fast and extremely small electronic components, for example.
In 1931, Duke Ellington and Irving Mills even dedicated a song to the phenomenon of swing which they called "It Don't Mean a Thing, If It Ain't Got That Swing". Yet, to this day, the question of what exactly makes a jazz performance swing has not really been clarified. A team drawn from the Max Planck Institute for Dynamics and Self-Organization in Göttingen and the University of Göttingen recently carried out an empirical study into the role played by microtiming in this process - a topic that has hitherto been controversial among music experts and musicologists.
The concert of motion that fish schools are famous for isn't merely an elaborate display of synchronized swimming. Their seemingly telepathic collective movement is part of a time-tested strategy for improving the group's chances for survival as a whole, from defense against predators to food-finding and mating.
A study published in Physical Review X is offering new details that show how the aquatic flows created by certain schools of fish can benefit each of its individual members in yet another way -- hydrodynamically.
Anyone who's read "The Lorax" will recognize that certain species serve as the foundation of their ecosystems. When the truffula trees disappear, so to do the swomee-swans and bar-ba-loots. However, the same is not necessarily true the other way around.
Researchers identified two proteins -- mutant tumor protein 53 (mtp53) and poly-ADP-Polymerase (PARP) -- that are present and interacting with DNA during the replication process in patients with triple negative breast cancer.
Suppressing these proteins through a combination of existing PARP-inhibiting therapies could be an effective way to interrupt the development of triple negative breast cancer cells and offer the first targeted treatment for this form of the disease.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots -- tiny islands of confined electric charge that act like interacting artificial atoms. Such "coupled" quantum dots could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer. Moreover, the patterns of electric charge in the island can't be fully explained by current models of quantum physics, offering an opportunity to investigate rich new physical phenomena in materials.
Researchers from the Moscow Institute of Physics and Technology have discovered an additional component in ATP synthase, a molecular machine that produces the energy-conserving compound in all cellular organisms. The new unique features of the ATP synthase structure are described in detail in a paper in Scientific Reports.

January 29, 2020 - In the era of 'Dr. Google,' social media is a tremendous influence on patients interested in cosmetic surgery, and with more than two billion users - representing almost one-third of the internet - YouTube has emerged as an essential platform for reaching people interested in plastic surgery.
PROVIDENCE R.I. [Brown University] -- Researchers from Brown University have designed a new type of wing that could make small fixed-wing drones far more stable and efficient.
WASHINGTON, January 29, 2020 -- Most nuclear data measurements are performed at accelerators large enough to occupy a geologic formation a kilometer wide, like the Los Alamos Neutron Science Center located on a mesa in the desert. But a portable device that can reveal the composition of materials quickly on-site would greatly benefit cases such as in archaeology and nuclear arms treaty verification.
