NASA analyzed the soil moisture in southeastern Texas before and after Harvey made landfall and found the ground was already somewhat saturated. NASA-NOAA’s Suomi NPP Satellite provided a night-time look at Harvey after it moved into the Gulf of Mexico, and NOAA’s GOES East satellite provided a look at the storm after it made its final landfall near the Texas-Louisiana border on Aug. 30.

Immunotherapy is an emerging field in the global fight against cancer, even though scientists and clinicians have been working for decades to find ways to help the body’s immune system detect and attack cancerous cells. Doug Mahoney’s lab at the University of Calgary recently discovered an immunotherapy that uses existing cancer drugs in a whole new way.

An herb widely used in traditional Chinese medicine might hold the key to a new osteoporosis therapy that could prevent bone loss without causing side effects.

Using a compound derived from red sage, UBC researchers have found a way to selectively block an enzyme called Cathepsin K (CatK), which plays a major role in the breakdown of collagen in bones during osteoporosis. The findings were published in the Journal of Bone and Mineral Research.

A natural process that occurs during photosynthesis could lead to the design of more efficient artificial solar cells, according to researchers at Georgia State University.

During photosynthesis, plants and other organisms, such as algae and cyanobacteria, convert solar energy into chemical energy that can later be used as fuel for activities. In plants, light energy from the sun causes an electron to rapidly move across the cell membrane. In artificial solar cells, the electron often returns to its starting point and the captured solar energy is lost. In plants, the electron virtually never returns to its starting point, and this is why solar energy capture in plants is so efficient. A process called inverted-region electron transfer could contribute to inhibiting this “back electron transfer.”

A University of Alberta forestry professor has cracked a key mystery surrounding the mountain pine beetle.

After studying lodgepole pine trees in the Grande Prairie area that survived a pine beetle attack, U of A professor Nadir Erbilgin and his team discovered certain chemicals in the trees that produce high levels of resin—sticky sap—that overwhelms the insect.
