WATER WORLD Aging sewers impacting urban watersheds

Aging sewer systems are spilling a considerable amount of nitrogen into urban watersheds, diminishing both the quality of water and ecosystems' habitats. However, many studies documenting the impacts of nitrogen on urban environs have not properly estimated th... more

EARTH OBSERVATION Indra Incorporates Rapideye Satellite Capacity Into Its Earth Observation Service

Indra has signed an agreement making it the only company in Spain to market images from RapidEye's constellation of five satellites. This will strengthen the Earth observation service it provides for domestic and international public administrations, companies... more

MOON Artemis I to launch first-of-a-kind deep space biology mission

Space radiation is like a demolition derby - on the nano scale. High-energy galactic cosmic rays and bursts of solar particles permeate deep space. These types of radiation can wreak havoc on electronics and living cells alike. BioSentinel's main job is to mon... more

STELLAR CHEMISTRY Extending LIGO's reach into the cosmos

In the future, as more and more upgrades are made to the National Science Foundation-funded LIGO observatories-one in Hanford, Washington, and the other in Livingston, Louisiana-the facilities are expected to detect increasingly large numbers of these extreme ... more

STELLAR CHEMISTRY NASA Team Takes on a New Optical Challenge - the Lyman Alpha Limit

Now, they're attempting to set another record. Manuel Quijada and his team, optical experts at NASA's Goddard Space Flight Center in Greenbelt, Maryland, are investigating techniques for creating highly reflective aluminum mirrors sensitive to the infrared, op... more

ENERGY TECH X-rays reveal another feature of high-temperature superconductivity

Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivit... more

STELLAR CHEMISTRY Revolutionary camera allows scientists to predict evolution of ancient stars

Scientists at the University of Sheffield have been working with HiPERCAM, a high-speed, multicolour camera, which is capable of taking more than 1,000 images per second, allowing experts to measure both the mass and the radius of a cool subdwarf star for the ... more

STELLAR CHEMISTRY Astronomers pinpoint elusive galaxy after decade-long hunt

An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy has managed for the first time to determine the distance of the galaxy HDF850.1, well-known among astronomers as being one of the most productive star-forming g... more
