En el desenlace del video expuesto en texto, el gato...

En dicho video, Adrianna Joy y sus amigas grababan un tutorial de peinados; las tres niñas en primer plano se crenchaban el pelo cuando sorprendidas comenzaron a mirar la lámpara que estaba a sus espaldas. "¿Está bailando?", preguntaba inocentemente una de las niñas señalando al gato debajo de la pantalla de la lámpara; pero poco tardaron las presentes en percatarse de que la mascota de la casa estaba en problemas. En la escena, se ve al gato moviéndose frenéticamente como si se estuviera electrocutando bajo la caperuza de una lámpara de piso. Los gritos de las jovencitas se confundían con los maullidos del animal. Nadie sabía qué era lo que en realidad sucedía. Lo primero que hizo Adrianna fue intentar sacar al gato de la lámpara, pero terminó mandándolo al suelo. Ella misma se acercó a la cámara y la apagó. El video vio la luz gracias al hermano de Adrianna, quien logró recuperarlo después de varios meses y publicarlo en las redes sociales. Ante la insistencia de los usuarios sobre la suerte del gato, a su dueña no le quedó más que responder a través de Instagram con otro video. Ante la respuesta, algunos expectadores sádicos que gozaban con el sufrimiento de la mascota quedaron decepcionados y no volvieron a mirar el video con la misma retorcida morbosidad. Por fortuna, no pasó de un susto; el gato, en realidad, maullaba porque se había atorado entre las piezas metálicas de la lámpara. Jamás recibió una descarga eléctrica. Asunto resuelto y miles de usuarios ya pueden respirar tranquilos.

Sunflowers Make Bees Poop—a Lot. Here's Why That's Good
Paragraph	Text
[1]	Bumblebees and other pollinators face many threats, including pesticide exposure,
[2]	climate change, habitat loss due to agriculture and development, and pathogens
[3]	that ravage multiple species. But a recent finding may help lighten their load.
[4]	Previous studies have shown sunflower pollen can work like a medicine for
[5]	bumblebees afflicted by a parasite called Crithidia bombi, a single-celled organism
[6]	that takes up residence in the bee's gut [and harms their health]. But scientists couldn't
[7]	explain how sunflower pollen vanquished C. bombi—did it boost the bees' immune
[8]	function, or perhaps poison the parasite directly?
[9]	New research, published in the Journal of Insect Physiology, shows the answer is
[10]	deceptively simple. "Sunflower pollen makes bumblebees poo a whole lot," says lead
[11]	author Jonathan Giacomini, which flushes the parasite out.
[12]	Plant products like nectar and pollen are a treasure trove of potential insect medicines
[13]	that scientists are just beginning to understand, he adds. "There are natural things out
[14]	there that bees are interacting with that can be beneficial for them," Giacomini says.
[15]	And by making changes to the landscape, scientists hope we can help give bees a
[16]	fighting chance.
[17]	Plant power
[18]	If you happen upon a fuzzy, buzzing, flying creature in eastern North America, there's
[19]	a strong chance it's a common eastern bumblebee (Bombus impatiens). Yellow and
[20]	black striped with a rump covered in soft hairs, they're social insects that live in
[21]	colonies and love a good crevice—they build their homes in birdhouses, woodpiles,
[22]	abandoned burrows, and dense grasses.
[23]	[They] are important pollinators, both in the wild and in agriculture, where they're raised
[24]	and used to pollinate crops including tomatoes and pumpkins. Like other pollinators,
[25]	bumblebees face many threats, and C. bombi isn't even the biggest bumblebee
[26]	bugaboo. On its own, the parasite doesn't have much of an effect on a bumblebee's
[27]	health. But when food is scarce, C. bombi can shorten a bee's lifespan and even
[28]	reduce the number of young queens a colony can produce.
[29]	Lynn Adler is an evolutionary ecologist at the University of Massachusetts Amherst
[30]	who studies interactions between plants and insects. For years, she and longtime
[31]	collaborator Rebecca Irwin at North Carolina State University suspected pollinators
[32]	might be getting dosed by flowers since plants often invest chemically active
[33]	compounds into their nectar and pollen to help their genetic payload arrive at
[34]	its destination.
[35]	"Many plant defensive compounds can be medicinal at certain doses," Adler says. After
[36]	all, "most of our human medicines come from plants."
[37]	Giacomini discovered the effect of sunflower pollen as an undergraduate working in
[38]	Adler's lab in 2018. From [these] very first tests, sunflower pollen dramatically reduced
[39]	C. bombi parasite load in common eastern bumblebees, often clearing infection
[40]	completely. "We've been shocked at how consistent and effective sunflower pollen
[41]	has been," Adler says.
