Aging usually improves the flavor of cheese, but that's not why some very old cheese discovered in an Egyptian tomb is drawing attention. Instead, it's thought to be the most ancient solid cheese ever found, according to a study published in ACS' journal Analytical Chemistry.
Reports from cannabis users that the drug reduces the symptoms of inflammatory bowel disease (IBD) may finally be explained by new research from the University of Massachusetts Medical School and the University of Bath showing that endocannabinoids help control and prevent intestinal inflammation in mice.
As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular man-made pesticide. The implications of this discovery, announced today in Science, led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales.
Hurricane Harvey made landfall in Texas on August 25, 2017, bringing more than 50 inches of rain and extreme flooding to the city of Houston. In addition to wreaking havoc on buildings and infrastructure, urban floodwaters harbor hidden menaces in the form of bacteria that can cause disease. Now, researchers have surveyed the microbes that lurked in Houston floodwaters, both inside and outside of homes. They report their results in Environmental Science & Technology Letters.
Doxorubicin is a chemotherapy drug used in ovarian, bladder, lung, thyroid and stomach cancers, but it carries a harmful side effect. The drug causes a dose-dependent heart toxicity that can lead to congestive heart failure. Researchers have found an important contributor to that heart pathology -- disruption of the metabolism that controls immune responses in the spleen and heart. This dysregulated immunometabolism impairs resolution of inflammation, and chronic, non-resolving inflammation leads to advanced heart failure.
The anemonefish is more familiarly known as the clownfish, as its bright coloration reminds of the face painting of a clown. The striking and unique coloration consists of white stripes on an orange background, but its biological function has remained a mystery thus far. Now, a study by the researchers of the University of Turku and the University of Western Australia has revealed new information on the coloration of the fish.
Estrogen treatment promotes apoptotic death in cancer cells through balanced upregulation of liganded and non-liganded pathways of estrogen receptor activation.
Drinking water from wells in rural north central Pennsylvania had low levels of pharmaceuticals, according to a study led by Penn State researchers.
When dairy cattle consume aflatoxin-contaminated feed, they are lethargic, their appetite wanes, they produce less milk, and their immune system goes awry. Some of those symptoms relate to oxidative stress, in which dangerous free-radicals bounce around, damaging cells. In a new study, researchers at the University of Illinois investigated the potential of injectable trace minerals to reduce the damage and keep dairy cows healthier.
An extensive experiment testing the immune effects of lab-designed nucleic acid nanoparticles found varying and specific responses from various immune cells, depending on each particle's shape and formulation, a finding that may encourage further study of the particles' therapeutic use. The researchers propose that they may have discovered an auxiliary system for managing immune response -- a molecular 'alphabet' for communicating with the human immune system.
