Researchers from Case Western Reserve University School of Medicine in collaboration with researchers from Dartmouth Geisel School of Medicine and RWTH Aachen University (Germany) have adapted virus particles—that normally infect potatoes—to serve as cancer drug delivery devices for mice. But in a recent article published in Nano Letters, the team showed injecting the virus particles alongside chemotherapy drugs, instead of packing the drugs inside, may provide an even more potent benefit.

They are all around you! Most plastics, conductive polymers, and even medicines derive from molecules with a double bond between two carbon atoms, C=C. These molecules are called olefins and are mainly produced from fossil fuels through an energy-intensive and polluting process known as steam cracking. It requires temperatures of 800°C and produces the greenhouse gas carbon dioxide. Needless to day, alternatives to this process which could bring environmental and economic benefits are highly sought after.

Cell biologists at the University of Toronto have discovered animals can adapt their ability to see even with extreme changes in temperature.

The researchers looked deeply into the eyes of catfish living in cold-water streams at altitudes of up to nearly three kilometres in the Andes Mountains to find out how. Their findings are published in Proceedings of the National Academy of Sciences.

Shortly after lasers were first developed in the 1960s, LiDAR – whose name originated as a combination of “light” and “radar” – capitalized on the newly unique precision they offered for measuring both time and distance. LiDAR quickly became the standard method for (3-D) land surveys and is now used in a multitude of sensing applications, such as self-driving cars.
By scanning areas of land with lasers, often from airplanes, LiDAR’s travel-time measurements for light reflected back from the scanned area provide the distances that make up a resulting high-resolution topography.

The intensive management of grasslands is bad for biodiversity. However, a study by the Terrestrial Ecology Research Group at the Technical University of Munich (TUM) has brought a ray of hope: If different forms of management are optimally distributed within a region, this can lead to higher yields without the loss of insect species. In ideal cases, this will allow even more species to find habitats that are optimal for them. What is crucial here is that management is planned at the landscape level.

A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

Israel is subjected to sand and dust storms from several directions: northeast from the Sahara, northwest from Saudi Arabia and southwest from the desert regions of Syria. The airborne dust carried in these storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.

Farmers earn more profits when there is demand for corn for biofuel instead of for food only. This can lead some to convert grasslands and forests to cropland. This conversion, also called indirect land use change, can have large-scale environmental consequences, including releasing stored carbon into the atmosphere. To penalize the carbon emissions from this so-called indirect land use change, the USEPA and California Air Resources Board include an indirect land use change factor when considering the carbon savings with biofuels for their compliance with the federal Renewable Fuel Standard or California’s Low-Carbon Fuel Standard.

Sometimes, a little snot goes a long way. And not just in the physical, stretchy sense. Today, some decade-old snot collected from the sinuses of cancer patients revealed a new technique to forecast how flu evolves.

NOAA met with ocean observations experts from six nations and 13 global organizations in May 2017 in Honolulu, Hawaii, to plan for the redesign of the Tropical Pacific Observing System by the year 2020 (TPOS 2020).

TPOS is an ocean-based monitoring network comprised of a variety of observing technologies, operated by NOAA and other foreign partners.  This network provides the essential ocean data needed to understand important environmental phenomenon and develop weather and climate forecasts for the US and countries around the world.
