Kenyan conservationist Paula Kahumbu leads a new generation of Africans who are taking control of their environmental future
In the cool and serene area of Karen, near Nairobi, in the offices of the conservation organisation she has built, Paula Kahumbu eats chicken and rice and talks about a revolution.

Continue reading...Look carefully at the most uppermost branches upon the great family tree of life on Earth, and near the top you will see a tiny twig labelled “panda”. It is re-growing. Slowly, it is getting sturdier.
Pandas are doing better than they were. In fact, this week, they have been officially downgraded in their conservation status from “endangered” to “vulnerable”, in the International Union for Conservation of Nature's latest “red list” update. The IUCN's annual announcement details the survival fortunes of every leaf upon life's great tree. It is nature's version of the FTSE 100, turned on its head.

Has the social media site been good for our mental health or not? The evidence isn't straightforward, researchers say, despite lots of study. How Facebook makes you feel may depend on how you use it.
In 1954, Brown v. Board of Education declared that separate schools for black students and white students should be dismantled with “all deliberate speed.” However, in recent decades, schools have re-segregated to the levels they were just after Brown. In this video, Atlantic education editor Alia Wong speaks to the U.S. Secretary of Education John King, Jr. about his new plan to integrate schools. King's policy changes will expand a system known as “school choice” that permits students to go to schools outside their neighborhoods and theoretically allows parents to voluntarily integrate schools. But, D.C. parent Natalie Hopkinson argues that schools will continue to re-segregate if the federal government does not intervene more forcefully. “As long as we rely on [parental] choice, we will continue to have the same result,” she says. “White parents will not send their kids to schools unless they are already white.”

Ferdinand Hayden Scientist of the Day
Ferdinand Vandeveer Hayden, an American geologist, was born Sep. 7, 1829.
Another of the world's grand tech exhibitions is now in the books, with Berlin hosting what might have been its most varied and intriguing IFA in years. Like other shows, this one had its oddities, such as LG's fridge running Windows 10, but what stood out to me was the practicality and immediate emotional appeal of many of the new products on show. With modern technology now mainstream and reaching a plateau of good-enough hardware, companies are spending less time chasing and explaining new specs and more of their effort on humanizing and styling out their latest gear.
This is not a criticism. I think there's a great deal of substance in style. It is the substance of design.

Researchers find that one reason some people cheat over and over again is because we all tend to suffer from "unethical amnesia" — our minds are prone to forgetting the bad stuff we've done.

Scientists have demonstrated a method for making 3-D images of structures in biological material under natural conditions at a much higher resolution than other existing methods. The method may help shed light on how cells communicate with one another and provide important insights for engineers working to develop artificial organs such as skin or heart tissue.

In this image, gold nanorods, embedded in a cell-populated collagen gel, scatter light as viewed under a darkfield microscope. The collective excitation of electrons in the conduction band of gold nanoparticles arising from resonance with incident-visible radiation is referred to as localized surface plasmon resonance. This excitation leads to resonant Rayleigh light scattering. Because of this strong scattering, individual nanoparticles, much smaller than the wavelength of light, can be observed using an optical microscope. There has been considerable interest in resonant Rayleigh scattering from gold and silver nanoparticles for biological and chemical analysis. In this application, a fibroblast-seeded collagen gel, an in vitro material system often used to model wound healing, is embedded with nanoparticles. The pattern of scattered light will be tracked using computerized pattern matching and image correlation techniques to measure the deformation that occurs as the collagen gel contracts, in a simulation of the formation of scar tissue. It is hoped that these small scale measurements will illustrate local heterogeneity in the mechanical response of the material.
