- Rhythmic expression of key genes is essential for maintaining proper timekeeping of the body's clock. In addition, rhythmic degradation of clockwork proteins is also crucial. However, surprisingly, researchers know little about these specific processes.
- McMaster Engineering researchers Emily Cranston and Igor Zhitomirsky are turning trees into energy storage devices capable of powering everything from a smart watch to a hybrid car.
- Vicky Schneider, 361° Division at The Genome Analysis Centre, along with UK and European partners, has reviewed key aspects of standards and formats of biological data to highlight the importance of data integration and management tools for biologists.
- Flying cars, hoverboards and video chat - a very futuristic vision for the year 2015 was presented in the movie "Back to the Future Part II", released in 1989. Now, shortly before "Back to the Future Day" on October 21st, 2015, it is time to check whether reality has indeed kept up with the daring predictions of the 80s.
- Tropical Storm Oho intensified into a hurricane on October 6 and appeared to have a "tail" in Infrared NASA satellite imagery. Oho is the seventh hurricane of the 2015 season in the North Central Pacific Ocean.
- Many Americans buying new cars these days are baffled by the rush of new safety features.
- Police officers and firefighters are leveraging big data to do their jobs more efficiently and more accurately.
- The second set of papers related to the remarkable discovery of Homo naledi, a new species of human relative, have been published in scientific journal, Nature Communications, on Tuesday, 6 October 2015.
Team reports detailed analysis of electrical characteristics of a tiny transistor made from two quantum dotsA single-electron transistor (SET) is an electrical device that takes advantage of a strange quantum phenomenon called tunneling to transport single electrons across a thin insulator. The device serves as an on/off switch on the tiniest scale and could play an important role in quantum computing.
- If you've ever waited on an airport runway for your plane to be de-iced, had to remove all your food so the freezer could defrost, or arrived late to work because you had to scrape the sheet of ice off your car windshield, you know that ice can cause major headaches.
- Scientists at the U.S. Department of Energy's Ames Laboratory have developed molecular modeling simulations and new theoretical formulations to help understand and optimize catalytic reactions that take place in chemical environments where the reactant "ingredients" for catalysis are not well mixed.
- NOAA and the other Deepwater Horizon Natural Resource Trustees today released 15-year comprehensive, integrated environmental ecosystem restoration plans for the Gulf of Mexico in response to the April 20, 2010 Deepwater Horizon oil rig explosion and spill. Implementing the plan will cost up to $8.8 billion. The explosion killed 11 rig workers and the subsequent spill lasted 87 days and impacted both human and natural resources across the Gulf.
- Does Jupiter protect us from harm, or cause more objects to change trajectory and head towards Earth?
- When fictional astronaut Mark Watney becomes stranded alone on the Red Planet in the novel and film "The Martian," people and technology from NASA's Jet Propulsion Laboratory in Pasadena, California, play important roles in his castaway adventure. Acclaimed for its attention to scientific and technical detail, "The Martian" is steeped in decades of real-life Mars exploration that JPL has led for NASA.
- (Phys.org)—Australian biologist John Alroy, with Macquarie University has published a paper in Proceedings of the National Academy of Sciences outlining his study and analysis of two groups of animals; amphibians and reptiles, focusing on extinction rates of the past and likelihood of extinction in the future. He suggests the data indicates that unless something changes, frogs are on a path of mass extinction.
- In the arid plains of the southern New Mexico desert, between the site of the first atomic bomb test and the U.S.-Mexico border, a new city is rising from the sand.
- A WageSpot smartphone application released in the United States on Tuesday dove into a historically taboo topic—how much people get paid.
- X-ray crystallography reveals the three-dimensional structure of a molecule, thus making it possible to understand how it works and potentially use this knowledge to subsequently modulate its activity, especially for therapeutic or biotechnological purposes.
- Geological relics from the far reaches of the solar system are the focus of a quest by the fireball hunting team at Curtin University.
- (Phys.org)—A team of researchers with the University of Cape Town and the University of KwaZulu-Natal, both in South Africa, has found an example of a seed from a plant using mimicry to fool a beetle. In their paper published in the journal Nature Plants, the team describes their study of the relationship between the seeds and beetles and the deceptive dispersal they witnessed.
- Environmentalists called Tuesday for a pollution tax in the Indian capital after a top court ordered the city and national governments to quickly come up with a plan to clean New Delhi's notoriously filthy air.
- Scientists often use satellites, supercomputers or high-tech arrays of instruments to show how the climate is changing.
- A team at The University of Manchester is testing a Volkswagen diesel engine to try to get an accurate picture of how polluting it is.
- Scientists investigating how to control take-all, a fungus that lives in soil and infects wheat roots to cause disease, have discovered that different varieties of wheat have distinct and lasting impacts on the health of the soil in which they are grown.
- Breaking up is never easy, and while 20 years ago there may well have been little or no post break-up contact between exes, 21st century technology – from social media to Whatsapp – means there are many new ways to open old wounds. With so many communications channels with which to get hold of people, and with so much of our lives visible online through such things as Facebook, it's easy to keep an eye on our exes once we've parted.
- A blend of two polymers can be used to boost the efficiency of LEDs (light-emitting diodes), according to a research study published in the journal Applied Materials Today. Richard Friend of the Cavendish Laboratory, at the University of Cambridge and colleagues, have blended poly(9,9-dioctylfluorene) (F8) and a poly(para-phenylenevinylene) (PPV) copolymer known as Super Yellow (SY) and used cesium carbonate in their LED's negative electrode to minimize quenching and give them ultrahigh efficien
- At present, tiny magnetic whirls – so called skyrmions – are discussed as promising candidates for bits in future robust and compact data storage devices. At the University of Hamburg these exotic magnetic structures were recently found to exist in ultrathin magnetic layers and multilayers, similar to the ones used in current hard-disk drives and magnetic sensors. However, up to now an additional magnet was necessary for a read-out of skyrmions. Now researchers from the University of
Protein reactions identified with subatomic resolution—why some switch proteins are slower than othersUsing subatomic resolution, researchers have gained insights into the dynamic modus operandi of two switch proteins which are responsible for the import of compounds into the nucleus and for cell growth. The team headed by Prof Dr Klaus Gerwert from the Department of Biophysics at the Ruhr-Universität Bochum, together with partners from Dortmund and Shanghai, combined different methods in order to gain a resolution of one-hundredth of the atomic diameter. The current edition of the Journal
- A newly upgraded high-power laser at the Department of Energy's SLAC National Accelerator Laboratory will blaze new trails across many fields of science by recreating the universe's most extreme conditions, such as those at the heart of stars and planets, in a lab.
