Basic science in evaporating droplets
What happens if you slowly evaporate a droplet containing dissolved particles? The question sounds simple, but it involves a surprising amount of basic physics and mathematics. Hanneke Gelderblom of the University ...
Farmers want water 'banked' for future droughts
Australian farmers want excess water from large floods to be 'banked' in aquifers, for use in dry times.
The lotus's clever way of staying dry (w/ Video)
An ancient Confucian philosopher once said, "I love the lotus because while growing from mud, it is unstained."
Wallowing in mud is more than just temperature control
Stabilisation of microdroplets using ink jet process
Progress means that many things that are used in everyday life are becoming more manageable, practical and generally smaller. This also applies to biological and chemical experiments. To save material and ...
Insects hold atomic clues about the type of habitats in which they live
Scientists have discovered that insects contain atomic clues as to the habitats in which they are most able to survive. The research has important implications for predicting the effects of climate change on the insects, ...
Researchers make major step in improving forecasts of weather extremes such as floods, droughts
(PhysOrg.com) -- Moisture and heat fluctuations from the land surface to the atmosphere form a critical nexus between surface hydrology and atmospheric processes, especially those relevant to rainfall. While current theory ...
NASA sees new salt in an ancient sea
(Phys.org) -- The expansion of massive salt evaporation projects on the Dead Sea are clearly visible in this time series of images taken by Landsat satellites operated by NASA and the U.S. Geological Survey.
One tree's architecture reveals secrets of a forest, study finds
(Phys.org) —Behind the dazzling variety of shapes and forms found in trees hides a remarkably similar architecture based on fundamental, shared principles, UA ecologists have discovered.
Researchers study change in the dead sea valley
Water evaporation in the Dead Sea valley contributes significantly to sea level drop and varies as a function of the season and meteorological conditions. Within the framework of the HEADS measurement campaign, ...
Scientist: Fire in Israel is a typical example of climate change effects in Mediterranean
The fire disaster in the Carmel Mountains near Haifa is a typical example of climate change effect and a taste of the future, says Dr. Guy Pe'er, one of the authors of Israel's first report to the UN on climate ...
Steroids control gas exchange in plants
Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the ...
Amalgam fillings are safe, but skeptics still claim controversy, researcher says
Dental amalgam has been proven safe and effective for years, yet unfounded controversy still surrounds it, a Medical College of Georgia researcher says.
Using light to build nanoparticles into superstructures
Scientists in the Center for Nanoscale Materials and Argonne's Biosciences Division have demonstrated a remarkably simple, elegant, and cost-effective way of assembling nanoparticles into larger structures ...
