Mitochondria are organelles that are known for providing the energy currency that fuels chemical reactions within cells, but they are also involved in other important processes vital for cell health including the innate immune response to pathogens like v

Proteins not only carry out the functions that are critical for the survival of cells, but also influence the development and progression of diseases. To understand their role in health and disease, researchers study the three-dimensional atomic structure

Brown bears foraging for food in the Shiretoko Peninsula of Hokkaido, Japan, have been disrupting tree growth in artificial conifer forests, according to a new study published in Ecology. Researchers compared soil and tree samples from human-forested plot

Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel genetic arrangement that may help a common bacterium in the human gut, Bacteroides fra

Asian elephants loudly mourn and bury their dead calves, according to a study by Indian scientists that details animal behavior reminiscent of human funeral rites.

An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark—and within just two minutes.

Put the word "evolution" into Google images and the results are largely variations on one theme: Ralph Zallinger's illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming taller and standing

Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. Th

From the fuzzy feeling on your teeth to the unfortunate condition of halitosis, bacteria shape mouth health. When dental illnesses take hold, diagnosis and treatment are necessary, but identifying the microorganisms behind an infection can be a lengthy an

Vanderbilt researchers have developed a new nanoparticle that can more get drugs inside cells to boost the immune system and fight diseases such as cancer.

The speed of innovation in bioelectronics and critical sensors gets a new boost with the unveiling of a simple, time-saving technique for the fast prototyping of devices.

Inspired by the design of space shuttles, Penn Engineering researchers have invented a new way to synthesize a key component of lipid nanoparticles (LNPs), the revolutionary delivery vehicle for mRNA treatments including the Pfizer-BioNTech and Moderna CO
