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.

The death of the world’s most famous grizzly bear on a highway in western Wyoming has made an orphan of its cub, but biologists say the youngster’s chances of surviving -- even with a chilly mountain winter coming on -- are good.
"High chances of survival going forward for the yearling, even being on his own,” said Grand Teton National Park bear biologist Justin Schwabedissen.
It should be reassurance to the many worrying, The Associated Press reported.
After grizzly No. 399 died in a vehicle strike Tuesday south of Jackson Hole, her male cub's fate has been a big topic of discussion on a popular Facebook page dedicated to following the bear and her previous cubs. Evidently unhurt by the crash, the cub hasn't been seen since.
Some online commenters say the cub — known informally as “Rowdy” or “Spirit” — should be found and rescued.
Others agree with the usual approach of wildlife managers: Don't interfere with nature. So far, no cub search has been announced.
Had the cub been born last winter, survival would be much less likely.
But this youngster's age of nearly two years, its healthy size and the season — almost time to den up, safe and snug for the winter — are factors working in his favor, according to Schwabedissen.
Perils for grizzlies in the region besides highways include getting shot when the smell of game carcasses draw them into unintentional confrontations with elk hunters. Others are killed when they acquire too much of a taste for apples, dog food, garbage and other human sources of food near homes and become a risk for people.
This 28-year-old momma bear was the oldest known reproducing female grizzly in the Yellowstone ecosystem. Starting in 2004, she birthed 18 cubs in eight litters and had a penchant for hanging out with them near roads in Grand Teton.
Such behavior made her a hit with tourists, sometimes drawing hundreds at a time and causing traffic jams. Dozens of wildlife photographers and scientists — she's named for a numbered tag they put in her ear — watched her as well.
She's not the only famous animal in the region. Last summer, a confirmed sighting of a rare white buffalo calf in Yellowstone stirred widespread excitement.
Just a handful of people saw the bison calf soon after it was born and there have been no sightings since. But according to Native American legend, the calf fulfills an old prophesy and foretells better times ahead.
In 2009, a 725-pound Yellowstone bull elk known by his ear tag number drew attention when he died at a ripe old age of at least 15. Famous for getting aggressive with other males — and cars — elk No. 6 suffocated after tripping on a fence and getting pinned between rocks on his back.
Other Yellowstone-area wildlife are known only in death, such as a wolf which a man ran down with a snowmobile and brought into a bar in western Wyoming before killing it last winter.
Grizzly No. 399 and her cub leave a more uplifting legacy: helping people appreciate grizzlies as their numbers in the Yellowstone region continue to rebound from just over 100 in the 1970s to around 1,000 today.
Some of her offspring have had cubs that are now much older than her youngest who's now out there alone, fending for himself.
“She truly was an icon and ambassador for not only for of her species but also the wildness of the Greater Yellowstone Ecosystem,” Grand Teton Superintendent Chip Jenkins said.
