Can Satellites Fill Gaps in Agricultural Water Monitoring?

As Earth’s population continues to rise and anthropogenic climate change threatens the habitability of parts of our planet, freshwater management is becoming a life-or-death issue for millions. Agriculture uses more of Earth’s freshwater than any other sector, primarily for crop irrigation. In places where water is scarce, policymakers are eager to regulate water […]

After decades of work, why don’t we have an HIV vaccine?

All these tiny breaks in the case could add up over time. “I wouldn’t be surprised if in a decade we have a vaccine with 50 percent protection,” Pulendran says. (That’s on par with the flu shot.) Paired with existing stopgaps, that could be what it takes to outmaneuver the powerful germ—no sci-fi cure-alls required. […]

The new generation solar, developed by TalTech, cells contribute to the green revolution

The biggest changes will take place in the energy production sector, which stands on the […]

New method sees fibers in 3-D, uses it to estimate conductivity

Each of the three methods used to visualize the fibers had pros and cons. Ray casting showed promise to become a powerful approach to estimate the orientation of fibrous materials with little curvature.

Tiny new species of sea blob hovers ‘like a hot air balloon’ over the seabed

Deep in an underwater canyon off the coast of Puerto Rico, there’s a party of balloon-like sea creatures keeping things festive in the abyssal depths. Their bodies are small — about the size of a golf tee (just over 2 inches, or 6 centimeters, long) — but they’re vibrant; when the creatures move and pulse, […]

China is about to collect the first moon rocks since the 1970s

For the first time in almost half a century, scientists are going to get their hands on new moon rocks. The Chinese space agency’s Chang’e-5 spacecraft, which landed on the moon around 10:15 a.m. EST December 1, will scoop up lunar soil from a never-before-visited region and bring it back to Earth a few weeks […]

Messengers of Gates’ Agenda: How the Cornell Alliance for Science Spreads Disinformation on behalf of the Bill and Melinda Gates Foundation – Independent Science News

Farmers practicing agroecology in Kenya

by Heather Day In October of this year, the Cornell Alliance for Science (CAS) hosted a webinar on “agroecology,” a concept that has attracted growing attention in recent years. Agroecology is a transdisciplinary science, practice, and social movement that offers a pathway for food system transformation. Yet, as soon as the webinar began, the moderator […]

High Climatic Response of High-Latitude Forests

Atmospheric CO2 rises and falls with the northern hemisphere winter and summer, respectively, and the amplitude of that seasonality is increasing. Is the vast boreal forest contributing to this trend, and, if so, why? Most models assume that increased CO2 stimulates photosynthesis, increased temperature stimulates respiration, and the difference between the two determines […]
