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.
With the emergence of the omicron variant, the U.S. is considering tightening international travel guidelines. The CDC said it might reduce the window for foreign travelers to submit a negative COVID-19 test from three days prior to one day before allowing entry.
Jill and Carlo cover the latest on Omicron, another school shooting in America and more. Plus, bidding farewell to 'transitory' inflation, and the controversy surrounding 'Lovely Bones' author Alice Sebold.
Sarav Arunachalam, air pollution scientist at the University of North Carolina at Chapel Hill, joins Cheddar Climate, where he discusses what he needs to happen when it comes to EV production on a global level to help reduce the effects of climate change.
The United Nations Secretary-General said this year that his agency's warning about climate change was a 'code red for humanity.' So how will political pledges to lower emissions, increase green energy, and ramp up electric vehicle infrastructure play out, and can we reverse some climate damage next year? Vijay Vaitheeswaran, Global energy & climate innovation editor for The Economist, and host of 'To a Lesser Degree,' The Economist’s podcast on climate change, joins Cheddar Climate to discuss what we can look ahead to in 2022, including global policy shifts and investments from the private and public sectors, holding global leaders accountable, and more.
In recent years, extreme weather events like flooding and wildfires have become more frequent, and more severe - and scientists say global warming is to blame. Climate crises could leave people in need of help, and that's where Global Rescue steps in. The crisis response firm employs former Navy Seals and Army Rangers to rescue travelers from climate-related emergencies. Global Rescue CEO Dan Richards joins Cheddar Climate to discuss.
Jennifer Lotito, president and COO at the non-profit (RED), joined Cheddar to discuss the CODE (RED) campaign as the organization looks to expand its mission to support both AIDS and COVID-19 relief. She explained that people can get involved in the campaign for Giving Tuesday and ahead of World AIDS Day by shopping (RED) branded products and even using credit card rewards points to add their own support. Lotito also pointed out that COVID-19 has also impacted HIV testing as people avoid clinics out of fear of the other pandemic.
NASA indefinitely delayed a spacewalk to repair an ISS antenna, citing concerns about space debris. It was unclear if the warning from the space agency to astronauts aboard the ISS was related to the recent destruction of a non-functioning Russian satellite.
