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.
NASA's Perseverance Rover unexpectedly has discovered volcanic rock on the surface of Mars. Scientists initially had thought the rocks were sedimentary in nature.
The deadly tornadoes that devastated Kentucky and five other states last weekend have brought climate change back to forefront of the conversation. Scientists say no single weather event can be pinned to climate change alone, but this December has been unseasonably warm, and warmer temperatures can make extreme weather events more likely. Jana Houser, associate professor of meteorology at Ohio University, joined Cheddar to discuss what role climate change might have played in these deadly tornadoes, and what can be done to prevent severe weather events like this from getting even worse in the future.
Even as tech giant Google implements a vaccination mandate, charging its employees to declare their vaccine status within a time frame or risk dismissal, the federal government is tangled up in the court system trying to impose one of its own. Cindy Cohn, the executive director of the Electronic Frontier Foundation, and Harry Nelson, founder and managing partner of Nelson Hardiman LLP, joined Cheddar to debate the ethics, efficacy, and legality surrounding the issue. While Cohn noted that she thinks the federal mandate might be legally sound, her organization is also concerned with a separate question of privacy. "At EFF what we're most interested in is the digital surveillance that's going along with some of these attempts to try to track and confirm whether people are vaccinated or not," she said.
There is a new way for investors to bet on cannabis - the AdvisorShares Poseidon Dynamic Cannabis ETF targets about 20 of the biggest names in U.S. cannabis. It comes at a time when it's still difficult for investors to access the space. Cheddar News cannabis reporter Chloe Aiello spoke with co-founder and managing director for Poseidon Investment Management, Emily Paxhia.
Joellen Russell, Professor at the University of Arizona, joins Cheddar Climate to discuss how poor academic curricula and misinformation online are hindering efforts to educate children about climate change, as well as how Science Moms is providing resources to moms to help create a safer world for their children.
Another successful spaceflight is in the books for Jeff Bezos' Blue Origin. The company's third human spaceflight blasted off from Van Horn, TX. on Saturday, lasting about ten minutes from takeoff to landing. The crew, which included former NFL star and current GMA host Michael Strahan, traveled to the edge of space and experienced a few minutes of weightlessness before the capsule descended back to earth. Andrew Chanin, CEO of ProcureAM, joined Cheddar's Opening Bell to discuss the significance of the launch.
The U.S. Government is making its first major move toward encouraging nuclear energy in the U.S., as it pushes toward a sustainable future. Scott Waldman, White House reporter for Politico's E&E News joined Cheddar News to break down the developments. "There's definitely an audience for this now since we're looking at the value of nuclear in terms of climate policy," he said, regarding the prospects for bipartisan support.
Google reportedly has announced that its employees must declare their vaccination status by January 18 or face a loss of pay, administrative leave, and eventual termination.
