Colombian Scientists Develop Supplement to Protect Bees from Pesticides
Bees from the apiary of the Universidad del Rosario raised for the research of the formula to protect the brain of bees and other pollinators affected by exposure to insecticides, which was patented in Britain under the leadership of researchers from the Faculty of Natural Sciences of the Universidad del Rosario, in alliance with the Department of Neuroscience of the University of Arizona - Reuters

Scientists in Colombia say they have developed a novel food supplement that protects bees' brains from pesticides, keeping the insects safe from neurological damage caused by agricultural chemicals.
Bees, as pollinators, are considered essential for the preservation of natural ecosystems and food production.
The plant-based supplement developed at Colombia's private Rosario University in Bogota, in partnership with the Department of Neuroscience at the University of Arizona and Colombian Universidad Javeriana, allows bees to cope with neurotoxins commonly used in agriculture and avoid having their motor system and memory harmed by the chemicals, Reuters reported.
"This is a nutritional solution to the problem bees face when exposed to pesticides," said Andre Riveros, associate professor at Rosario University. "The food induces them to develop a protection (against pesticides)".
The formula is created with flavonoids, plant-derived secondary metabolites known for their health benefits.
Sedated and then confined to small laboratory tubes, bees were fed one-by-one by scientists during initial development of the supplement.
Testing has now moved to real-world scenarios in a university apiary, explained Juan Jose Ovalle, a natural science student at the university.
"We already know that there are molecules that improve the bees' health, we already know that there are molecules that prevent neuronal damage caused by pesticides", Ovalle explained, adding it was important to continue the work to boost the effectiveness of these methods in supporting bees.

Rare Sahara Floods Bring Morocco’s Dried-up South Back to Life

In Morocco's southeastern desert, a rare downpour has brought lakes and ponds back to life, with locals -- and tourists -- hailing it as a gift from the heavens.
In Merzouga, an attractive tourist town some 600 kilometers (370 miles) southeast of the capital Rabat, the once-parched golden dunes are now dotted with replenished ponds and lakes.
"We're incredibly happy about the recent rains," said Youssef Ait Chiga, a local tour guide leading a group of German tourists to Yasmina Lake nestled amidst Merzouga's dunes.
Khalid Skandouli, another tour guide, said the rain has drawn even more visitors to the tourist area, now particularly eager to witness this odd transformation.
With him, Laetitia Chevallier, a French tourist and regular visitor to the region, said the rainfall has proved a "blessing from the sky".
"The desert became green again, the animals have food again, and the plants and palm trees came back to life," she said.
Locals told AFP the basin had been barren for nearly 20 years.

Last year was Morocco's driest in 80 years, with a 48 percent drop in rainfall, according to an October report from the General Directorate of Meteorology (DGM).
But in September, torrential rains triggered floods in southern parts of Morocco, killing at least 28 people, according to authorities.
The rare heavy rains come as the North African kingdom grapples with its worst drought in nearly 40 years, threatening its economically crucial agriculture sector.
Neighboring Algeria saw similar rain and flooding in early September, killing six people.
North African countries currently rank among the world's most water-stressed, according to the World Resources Institute, a non-profit research organization.
The kingdom's meteorological agency described the recent massive rainfall as "exceptional".
It attributed it to an unusual shift of the intertropical convergence zone -- the equatorial region where winds from the northern and southern hemispheres meet, causing thunderstorms and heavy rainfall.

- 'Climate change' -
"Everything suggests that this is a sign of climate change," Fatima Driouech, a Moroccan climate scientist, told AFP. "But it's too early to say definitively without thorough studies."
Driouech emphasized the importance of further research to attribute this event to broader climate trends.
Experts say climate change is making extreme weather events, such as storms and droughts, more frequent and intense.
In Morocco's south, the rains have helped partially fill some reservoirs and replenish groundwater aquifers.
But for those levels to significantly rise, experts say the rains would need to continue over a longer period of time.
The rest of the country is still grappling with drought, now in its sixth consecutive year, jeopardizing the agricultural sector that employs over a third of Morocco's workforce.

Jean Marc Berhocoirigoin, a 68-year-old French tourist, said he was surprised to find Yasmina Lake replenished. "I hadn't seen these views for 15 years," he said.
Water has also returned to other desert areas such as Erg Znaigui, about 40 kilometers south of Merzouga, AFP reporters saw.
While the rains have breathed life into Morocco's arid southeast, Driouech warns that "a single extreme event can't bring lasting change".
But last week, Morocco's meteorological agency said such downpours could become increasingly frequent, "driven partly by climate change as the intertropical convergence zone shifts further north".
