Ants could be the next line of defense against cancer.
A study published in the journal Proceedings of Royal Society B: Biological Sciences focused on Ants and their keen sense of smell. Ants use smell via their thin sensory appendages that sit on top of their heads to do almost everything, including hunt for food, spotting mates, and protecting their young.
In the study, scientists used pieces of a breast cancer tumor, which were grafted onto mice, and then trained 35 ants to associate urine from the infected mice with sugar. In analyzing, scientists detected that the ants would hover for longer periods of time near the sick mouse rather than the healthy one.
Using ants to detect cancers would be a cost-cutting tool. Currently, cancers are diagnosed by blood withdrawal, biopsies, and colonoscopies, which are all considered invasive as well as being expensive procedures. Utilizing ants to screen for cancer would be significantly more reasonable.
While dogs have similar capabilities in that they are able to detect cancer in humans through smell, they take much longer to train. Baptiste Piqueret, a postdoctoral fellow at the Max Planck Institute for Chemical Ecology in Germany, said ants would be the ideal animal to use because they have good memories, are easy to train and don't bite.
Though progress has been made with ants and their cancer detection capabilities, there is still more research to be done on their efficacy. The next phase of the study will be human trials to see if ants are able to sniff out cancers through human excrement.
Jurors in the trial against Theranos CEO Elizabeth Holmes have entered day six of deliberations. Holmes is accused of lying to investors about the functionality of a newly developed blood-testing technology. Andrew George, partner at Baker Botts, joined Cheddar to break down key points in the case and what the jury might be considering during their deliberations. He also noted that the rest of Silicon Valley, including Holmes' business partner, Ramesh "Sunny" Balwani, who is facing identical charges, is closely watching the outcome of deliberations — as it could set the tone for future regulations and Balwani's own trial.
According to researchers, the state of California's cap-and-trade program is currently being undermined by forest fires caused primarily by climate change. Over the past few years, trees that were set aside for the program have been releasing carbon as they continue to burn in fires. Climate Researcher and Policy Director at CarbonPlan Danny Cullenward, joined Cheddar to discuss more.
The CDC's latest update to its COVID-19 quarantine guidelines reduces the isolation period from ten days to just five for people who test positive but are asymptomatic. Dr. Bayo Curry-Winchell, regional clinical director at Carbon Health, spoke to Cheddar's Baker Machado about the new guidance. She noted that while the reduced quarantine time "makes sense," the CDC should also require that a person test negative after their quarantine and before interacting with the public. "There is science behind it. We know that the majority of illness happens, or transmission, one to two days before the onset of symptoms and then two to three days as you have symptoms. So there is science behind the reducement of the actual five days," she said.
Prices at the pump this year reached a seven-year high, and a new forecast from GasBuddy shared with CNN predicts that gas prices will only continue to rise in 2022 and that the national average could even reach $4.00 a gallon; however, analysts at GasBuddy say anything could happen when it comes to gas prices in the future, as the pandemic has made it difficult to make any predictions about the economy. Consumer Energy Alliance federal policy advisor Michael Zehr joins Cheddar News' Closing Bell to discuss.
As the Omicron variant is fueling a surge in COVID-19 cases, parents and schools are faced with tough choices between absences and outbreaks. Matt Barnum, a national reporter at Chalkbeat, joins Cheddar News to discuss.
Ron Gutman, Co-CEO of Intrivo, joins Cheddar News to discuss how the company is creating a test and tech solution for Covid testing called 2Gather, and how it's using data-driven digital diagnostics to make these tests widely available and affordable.
As 2021 winds down, the number of positive COVID-19 cases has surged dramatically with numbers not seen since the heights of the pandemic. Dr. Laolu Fayanju, the regional medical director at primary care provider Oak Street Health, joined Cheddar to discuss the numbers, how the healthcare system is handling the surge this time around, and what it means that the CDC just cut the quarantine time guideline in half for those who are infected. "These are incredibly high numbers because they reflect the transmissibility of the omicron variant," Fayanju said.
