Months-long real-time generation of a time scale based on an optical clock

Tue, 20 Mar 18 00:09:30 -0700

The National Institute of Information and Communications Technology (NICT) generated a real-time signal of an accurate time scale by combining an optical lattice clock and a hydrogen maser. The signal generated in this optical-microwave hybrid system continued for half a year without interruption. The resultant 'one second' deviated by 0.8 ns in half a year relative to TT(BIPM). This demonstration proves the capability to keep time with respect to the future optical definition of the second.

UNH Researchers Find Space Radiation is Increasingly More Hazardous.

Getting lost: Why older people might lose their way

Thu, 15 Mar 18 00:07:10 -0700

Researchers at the German Center for Neurodegenerative Disease (DZNE) have found a possible explanation for the difficulty in spatial orientation experienced sometimes by elderly people. In the brains of older adults, they detected an unstable activity in an area that is central for spatial navigation. The results are reported in the journal Current Biology. In the long term, these findings might open up new ways for detecting Alzheimer's disease.

Growing need for urban forests as urban land expands

Wed, 14 Mar 18 00:01:20 -0700

New research projecting urban land growth and updating urban forest values suggests that urbanization and urban forests are likely to be one the most important forest influences and influential forests of the 21st Century.

Mystery of purple lights in sky solved with help from citizen scientists

Wed, 14 Mar 18 00:06:50 -0700

When a thin purple ribbon of light appeared and starting glowing in the midnight sky over Regina, Canada, in 2016, Notanee Bourassa knew that what he was seeing was not normal. Having watched the northern lights for almost 30 years, he knew this wasn't an aurora. It was something else.

Ash from dinosaur-era volcanoes linked with shale oil, gas

Tue, 13 Mar 18 00:16:30 -0700

Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs' reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana.

UH optometrist investigates changes in eye structure in astronauts

Tue, 13 Mar 18 00:04:40 -0700

A University of Houston optometrist studies the vision of returning International Space Station astronauts and proves a structural change to their eyes.

Mowing the lawn less often improves bee habitat

Tue, 13 Mar 18 00:06:20 -0700

New research suggests that homeowners can improve habitat for bees by mowing the lawn less often.

Areas where homes, forests mix increased rapidly over two decades

Tue, 13 Mar 18 00:07:10 -0700

From 1990 to 2010, the nation's wildland-urban interface grew rapidly, increasing from 30.8 to 43.4 million homes (41 percent growth) and expanding in area from 143,568,227 acres to 190,271,144 acres in area, or 33 percent. The vast majority of new WUI areas were caused by new housing (97 percent), not an increase in wildland vegetation.

A revolutionary technique allows to image all the cells in a region of the brain

Mon, 12 Mar 18 00:00:30 -0700

An interdisciplinary group of physicists and biologists working on research into brain cells have come up with a new, revolutionary microscopy technique which for the first time allows images to be obtained of all the cells within a specified area of living brain tissue.

Humans behind majority of raptor deaths in Ontario, study finds

Mon, 12 Mar 18 00:00:20 -0700

University of Guelph researchers found that a majority of raptor deaths are due to trauma and starvation caused by urban expansion and other types of anthropogenic landscape alterations.

NASA's James Webb Observatory prepares for additional testing

Mon, 12 Mar 18 00:04:10 -0700

Engineers removed the combined optics and science instruments of NASA's James Webb Space Telescope from their shipping container in a high bay at Northrop Grumman Aerospace Systems in Redondo Beach, California, on March 8, signaling the next step in the observatory's integration and testing.

Arrested development: Hubble finds relic galaxy close to home

Mon, 12 Mar 18 00:07:00 -0700

Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient 'relic galaxy' in our own cosmic backyard.

The cause of low-level turbulence around Hong Kong International Airport

Mon, 12 Mar 18 00:15:10 -0700

The occurrence of low-level turbulence around Hong Kong International Airport, which can influence the landing and departure of aircraft and is closely related to aviation safety, is an important topic of study. By utilizing the Doppler Light Detection and Range (LIDAR) system at HKIA and radiosonde data at King's Park Meteorological Station, it was found that the possibility of turbulence occurrence is related to the strength of southerly winds.

Three NASA satellites recreate solar eruption in 3-D

Fri, 09 Mar 18 00:13:50 -0800

Scientists have developed a model that simulates how shocks following coronal mass ejections, or CMEs, propagate from the sun -- an effort made possible only by combining data from three different NASA satellites.

NASA's Webb Telescope to make a splash in search for interstellar water

Fri, 09 Mar 18 00:14:50 -0800

Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets.

JHU performs first laboratory simulation of exoplanet atmospheric chemistry

Thu, 08 Mar 18 00:07:00 -0800

Scientists have conducted the first lab experiments on haze formation in simulated exoplanet atmospheres, an important step for understanding upcoming observations of planets outside the solar system with the James Webb Space Telescope.

New 3-D measurements improve understanding of geomagnetic storm hazards

Thu, 08 Mar 18 00:01:00 -0800

Measurements of the three-dimensional structure of the earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.

Weather satellites aid search and rescue capabilities

Wed, 07 Mar 18 00:11:10 -0800

The same satellites that identify severe weather can help save you from it. NOAA's GOES series satellites carry a payload supported by NASA's Search and Rescue (SAR) office, which researches and develops technologies to help first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.

First look at Jupiter's poles show strange geometric arrays of storms

Wed, 07 Mar 18 00:03:40 -0800

With NASA's Juno spacecraft, scientists have gotten a good look at the top and bottom of the planet for the first time. What they found astounded them: bizarre geometric arrangements of storms, each arrayed around one cyclone over the north and south poles -- unlike any storm formation seen in the universe.

Comet Chury formed by a catastrophic collision

Tue, 06 Mar 18 00:02:10 -0800

Comets made up of two lobes, such as Chury, visited by the Rosetta spacecraft, are produced when the debris resulting from a destructive collision between two comets clumps together again. Such collisions could also explain some of the enigmatic structures observed on Chury. This discovery, made by an international team coordinated by Patrick Michel, CNRS researcher at the laboratoire Lagrange (CNRS/Observatoire de la Cote d'Azur/Universite de Nice-Sophia Antipolis 1).
