October 6, 2017 3:01 PM Using indigenous knowledge for better agricultural policies

Wa, Oct. 5, GNA – Agriculture is the backbone of Ghana’s economy with about 80 per cent of total agricultural production attributed to smallholder farmers including women. These farmers are faced with issues of environmental degradation and poor soil fertility, due to climate change yet it is amazing how smallholder farmers are able to use their own knowledge 75

September 21, 2017 12:51 PM Climate change challenges the survival of fish across the globe

Climate change will force many amphibians, mammals and birds to move to cooler areas outside their normal ranges, provided they can find space and a clear trajectory among urban developments and growing cities. But what are the chances for fish to survive as climate change continues to warm waters around the world? University of Washington researchers 90

August 31, 2017 1:03 PM U.S.-China mission rushes bomb-grade nuclear fuel out of Africa

ACCRA AND BEIJING—Dan Peng steps onto a narrow steel frame just above a 6-meter-deep pool, which holds a nuclear reactor about to go critical. Clad in a lab coat with a pocket radiation dosimeter, sweating in the stifling reactor hall here on the outskirts of Ghana's capital, the young nuclear physicist edges out to a tube jutting above the water's surface 128

August 21, 2017 11:02 AM The great American eclipse is finally here

But even as celestial bodies moved to align in the sky, terrestrial-bound bodies were scurrying in a mad last-minute scramble for the best vantage points to witness it. Procrastinators dashed from store to store in search of eclipse-safe glasses. Scientists nervously checked and rechecked their equipment at observatories and research airplanes across 105

August 21, 2017 7:45 AM The Solar Eclipse: What to Expect

Because of planetary geometry, the total eclipse can last less than one minute in some places, and as long as two minutes and 41 seconds in others. The eclipse’s longest point of duration is near a small town called Makanda, Ill., population 600. Around 1:15 p.m. Eastern time, the total solar eclipse will first reach Oregon’s coast. Then it will race for the next 90 or so minutes 112

August 10, 2017 11:45 AM Chinese satellite sends 'hack-proof' message

China has successfully sent "hack-proof" messages from a satellite to Earth for the first time. The Micius satellite beamed messages to two mountain-top receiving stations 645 km (400 miles) and 1,200 km away. The message was protected by exploiting quantum physics, which says any attempt to eavesdrop on it would make detectable changes. Using satellites 108

August 8, 2017 11:16 PM Women Who Chase the Sun

The total solar eclipse that will take place over North America in a couple of weeks is a chance for millions of people to experience an exciting event (with proper viewing glasses to protect our sensitive eyes, of course!). Given the population’s demographics, it stands to reason that about half of those who will be under the spectacle of totality will be women 127

July 30, 2017 2:51 PM Space capsule with 3 astronauts blasts off to orbiting lab

BAIKONUR, Kazakhstan (AP) - A Soyuz space capsule successfully blasted off for the International Space Station on Friday, carrying an American astronaut, a Russian cosmonaut and an Italian astronaut. NASA's Randy Bresnik, Russia's Sergei Ryazansky and Italy's Paolo Nespoli lifted off from the Russia-leased launch pad in Kazakhstan shortly after sunset 125

July 20, 2017 7:45 AM Dementia Field Shifts to Prevention

Reports reverse old stance that little can be done to prevent dementia LONDON -- With several failed drug trials and without full understanding of the etiology of Alzheimer's disease for developing better therapeutics, dementia specialists have shifted their focus to prevention. At this year's Alzheimer's Association International Conference, press briefings 102

May 26, 2017 2:17 PM Dubai employs a real-life RoboCop to help keep its streets safe

But carnage, in this case, isn't on the list of functions. What would you call a police officer that was also a robot? An automocop? Chrome constable? We're damned if we know. Regardless of what you call it, Dubai has just deployed one such robotic policeman on its streets. The Dubai Police Robot will be delivering swift justice, bullet by bullet, won't 56
