Since the early 1980s, agricultural scientist Tony Rinaudo has been fighting encroaching desertification in Africa. His methods are now helping to stop the relentless forward march of desert sands by preventing erosion and improving water retention in the soil.
Average lifespans are creeping up, and that's affecting views on aging. Sociologist François Höpflinger has looked at attitudes and discovered that most elderly people today feel much younger than they did in the 1960s.
Samuel Alemán from Tocoa in Honduras wants to know.
Pathogens are growing increasingly resistant to antibiotics, and multiresistant germs are a challenge that desperately needs addressing. Proteins called artilysins could usher in a new approach to treating multiresistant infections.
Future Urban Mobility - gridlock & emission free. Also: Innovative battery designs for e-cars, a new weapon in the war on bacteria, age is relative and trees and the encroaching desert in Africa.
Why medicines aren't equally effective for both men and women. Also, a special report from Sierra Leone about life after the Ebola outbreak. How to tell whether someone is telling the truth. And, deceptive tactics in the animal kingdom.
Lying and cheating aren’t just human behaviors. Plants and animals also use deception to lure prey or choose partners. Some of nature's most clever ruses are housed at Hamburg's Tierpark Hagenbeck.
How can forensic psychologists tell whether a witness or defendant is telling the truth?
What is their method? And what are the telltale signs? We’ll take a peek over Professor Niels Habermann’s shoulder.
Mauricio De La Torre from Bonn wants to know
In early 2016, the World Health Organization announced a vaccine for Ebola. Its success rate in West Africa was nearly 100%. Our report from Sierra Leone asks how the vaccine has changed life there.
Could a compound in green tea be used to treat Alzheimer’s patients? Can dancing slow the progress of Parkinson’s disease? Also: Sustainable large-scale greenhouses in Bavaria, and the how climate change is affecting animals in Greenland.
Bernard Amenya from St. Paul in the US wants to know:
Green tea has been a folk remedy for centuries, and its proponents believe it helps heal a wide range of conditions. Now a molecular biologist is looking at one compound in particular that could bring new breakthroughs in dementia therapy.
Researchers say that over the coming decades, people will interact a lot more with robots. In Japan, they're already developing the next generation of robots.
Why don't human beings have thick fur? Scientists say it's one reason the human race has developed the way it has. Plus: The art of sweating. Survival strategies. Are we becoming a robotic society?
...asks Shweta Gupta from Mumbai, India.
The human body has developed sophisticated responses to a range of threats, such as heat, cold, hunger, thirst, and danger.
It's not so widespread among animals, but humans are great at it: sweating. Sweat cools the skin, serving to naturally regulate body temperature. But there’s even more to sweat than you might realize.
Paleobiologist Christine Hertler says the loss of thick hair made extended periods of exertion possible in our ancestors. Effort generates heat, and sweating dissipates it. But for that to work, the skin has to be free of too much hair.
Ankur Chaudhari from Vyara, India wants to know.
The southern Pacific archipelago of New Caledonia boasts a rich variety of plant life. The unique, endemic species include so-called "hyperaccumulators" capable of mopping up toxic heavy metals like nickel. Researchers want to use them to help clean up soil contaminated with the metals.
Many plastics contain additives intended to make the material soft and elastic. These so-called plasticizers are now being detected in human blood and urine. Children are particularly affected and that is alarming scientists.
How can we keep microplastics out of rivers and lakes? More research needs to be done, but many scientists say an additional treatment stage in sewage plants is a promising solution.
A group of researchers had spent months on the Southern Ocean when water quality measurements unexpectedly revealed plastic fibers. The fibers from synthetic fabrics absorb harmful substances that attack the immune systems of many animal species.
