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.
Amazon plans to launch its first prototype satellites for Project Kuiper, an internet-from-space venture, in 2022. It's the first major step in the e-commerce giant's plan to rival SpaceX by building a network of satellites in space, providing internet to rural, underserved communities around the world. Loren Grush, senior science reporter for the Verge, discusses the project and how it could transform internet access moving forward.
The FDA is assessing whether the Moderna vaccine can cause heart problems in adolescents. Professor Peter Pitts, founder of the Center for Medicine in the Public Interest and former FDA Associate Commissioner, discusses what the FDA is looking into and what it means for the millions of kids yet to be vaccinated.
Pfizer posted an earnings beat in its third quarter, with revenue soaring over 134% thanks to solid Covid-19 vaccine sales. Pfizer also raised its outlook for the full-year, expecting revenue to surpass $80 billion. Peter Andersen, CEO & founder of Andersen Capital Management, joined Cheddar Movers to discuss.

Leaders around the world have come together to discuss plans to bring action towards the Paris Agreement along with solutions on how to solve the evolving climate change crisis at the COP26 Summit. President and CEO of Center for International Environmental Law Carroll Muffett, joined Cheddar to discuss more.
Rachel Cleetus, the policy director and lead economist of the climate and energy program for the Union of Concerned Scientists, joined Cheddar to break down some of the key goals from the COP26 summit and why leaders must focus on the science of climate change instead of getting bogged down by petty politics and the fossil fuel industry. "The main thing they have to do, make sure we're cutting our emissions sharply within this decade because the science shows that we have to cut global emissions in half by 2030 if we're going to meet our goals of averting some of the most catastrophic impacts of climate change," she said.
Coastal cities around the world are grappling with sea level rise. And building a seawall? Not so fast. While a sea wall can be effective in certain scenarios, it can make the effects of sea level rise worse. That’s why municipalities are looking into creative alternatives.
