Illinois Sportfish Recovery a Result of 1972 Clean Water Act, Scientists Report

Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

New Findings Explain How UV Rays Trigger Skin Cancer

Melanoma, a cancer of skin pigment cells called melanocytes, will strike an estimated 87,110 people in the U.S. in 2017, according to the Centers for Disease Control and Prevention.

Researchers Customize Catalysts to Boost Product Yields, Decrease Chemical Separation Costs

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy’s Oak Ridge National Laboratory.

Global Calcium Consumption Appears Low, Especially in Asia

Daily calcium intake among adults appears to vary quite widely around the world in distinct regional patterns, according to a new systematic review of research data ahead of World Osteoporosis Day on Friday, Oct. 20.

Nice Ice, Maybe? Husker Research Finds Ice Removal Can Be a Breeze

Water-repellent surfaces and coatings could make ice removal a literal breeze by forcing ice to grow up rather than just skate by, says a new study from the University of Nebraska-Lincoln and several Chinese institutions.

Living Mulch Builds Profits, Soil

Living mulch functions like mulch on any farm or garden except — it’s alive. No, it’s not out of the latest horror movie; living mulch is a system farmers can use to benefit both profits and the soil. While the system has been around for a while, scientists at the University of Georgia are making it more efficient and sustainable.

DNA Tests on Albatross Poo Reveal Secret Diet of Top Predator

A study that used DNA tests to analyse the scats of one of the world’s most numerous albatrosses has revealed surprising results about the top predator’s diet.

Hardy Corals Make Moves to Build Reefs from Scratch

Resilient species of coral can move to inhospitable areas and lay the foundations for new reefs, a study shows.

Separating methane and CO2 will become more efficient

To make natural gas and biogas suitable for use, the methane has to be separated from the CO?. This involves the use of membranes: filters that stop the methane and let the CO? pass through. Researchers at KU Leuven have developed a new membrane that makes the separation process much more effective.

University of Hertfordshire physicists track atmospheric particles producing Monday's red sky

Using a Lidar, a laser ranging instrument, at the University’s Bayfordbury Observatory near Hertford, the team monitored the height of the particles throughout the day. Laser pulses reflected from the particles show their arrival around midday, their growing height in the atmosphere, and their eventual departure in the evening.

The atmospheric profile was measured every second, allowing the changes in the particle layering to be observed throughout the day. The particles responsible for the red sky are seen as a diagonal stripe in the profile sequence. The layer of dust arrived over Hertford around 11:00 GMT at 1 km altitude, drifted past over the next 6 hours at progressively higher altitudes, and reached 2-3 km altitude by the time it moved away from Hertford around 18:00 UTC.
