Uncovering a cellular process that leads to inflammation

Investigators have identified several steps in a cellular process responsible for triggering one of the body's important inflammatory responses. Their findings open up possibilities for modulating the type of inflammation associated with several infections and inflammatory diseases.

Sports concussions increase injury risk

Concussions are an unfortunate reality of contact sports at junior and senior levels. Now, sports experts are suggesting extended recovery times may be needed for youth athletes suffering from head trauma as new research shows a concussion can increase future injury risk by 50%.

Study shows ancient Alaskans were freshwater fishers

A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

New insights on bacteria that causes food poisoning

A joint research group has clarified how pathogenic genes in some Providencia spp., which have gained attention as causative agents of food poisoning as well as enterohemorrhagic Escherichia coli. O157 and Salmonella, are transferred within bacterial cells. Their findings are expected to provide new insights into the identification of infection routes of Providencia spp. and the establishment of...

42,000-year-old Mongolian pendant may be earliest known phallic art

The human predilection for phallic imagery is well documented—just look at the scrawling in any high school locker room. A pendant recently found in northern Mongolia suggests our species has been artistically recreating the penis for at least 42,000 years. According to researchers behind a study of the pendant, published this week in Nature Scientific Reports , the...

Humanity’s groundwater pumping has altered Earth’s tilt

While spinning on its axis, Earth wobbles like an off-kilter top. Sloshing molten iron in Earth’s core, melting ice, ocean currents, and even hurricanes can all cause the poles to wander. Now, scientists have found that a significant amount of the polar drift results from human activity: pumping groundwater for drinking and irrigation. “The very way the planet wobbles is...

Researchers create new imaging technique based on photoswitchable Raman probe

There are various ways to image biological samples on a microscopic level, and each has its own pros and cons. For the first time, a team of researchers, including those from the University of Tokyo, have combined aspects from two of the leading imaging techniques to craft a new method of imaging and analyzing biological samples. Its concept, known as RESORT, paves the way to observe living...
