Obesity linked to neurodegeneration through insulin resistance

Researchers have discovered a link between obesity and neurodegenerative disorders like Alzheimer's disease. Using the common fruit fly, the research shows that a high-sugar diet -- a hallmark of obesity -- causes insulin resistance in the brain, which in turn reduces the ability to remove neuronal debris, thus increasing the risk of neurodegeneration.

An optical and electrically driven single-molecule Raman switch

The role of molecular junctions in nanoelectronics is most often associated with electronic transport; however, their precise characterization hinders their widespread development. Recently, most research has focused on investigating molecular junctions based on electronic characterization.

Crohn’s disease can be detected in blood eight years before symptoms show, finds study

Findings may enable earlier treatment before severe damage happens requiring life-changing surgerySigns of the debilitating bowel condition Crohn’s disease can be detected in routine blood tests up to eight years before the onset of symptoms, and up to three years before a diagnosis of ulcerative colitis. The discovery suggests that early stages of inflammatory bowel diseases may begin far...

Study shows animals like crickets use the ground to amplify calls

When animals "sing" sitting on the ground—such as when crickets chirp—their volume and reach increase dramatically, by as much as ten-fold. This result from a study by Western researchers, published today in the journal PNAS, contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.

Education is key to curbing antimicrobial resistance in cats, study says

Better education for cat owners, more communication from veterinarians, increased drug choices and cheaper, rapid diagnostic tools can help improve antimicrobial use in cats, which has important implications for rising antimicrobial resistance in animals and humans, according to two new papers by Cornell researchers.

Volcanic eruption: Scientists perform volcanic scenarios to develop response plan

What would happen if a volcano were to erupt tomorrow in New Mexico? How prepared as we as a society for an event like this to occur? When volcanic unrest occurs, both academic and government agencies need to have advanced fundamental understanding of the volcanic system with coordination before, during and after the event. This necessity has prompted the development of a response plan.

Research improves formable cellulose-based food packaging to replace single-use plastic

In a pilot-scale study to find alternative raw materials for rigid plastic packages, VTT Technical Research Center of Finland has obtained unprecedented maximum limits of its highly extensible formable cellulose-based webs used for rigid packaging applications. The results enable the manufacturing of a wide range of sustainable 3D packaging solutions that were previously unattainable.

Study finds that colostrum is key to saving beef calves from trouble

In a pair of recent studies, researchers examined risk factors that contribute to insufficient antibody transfer to newborn beef calves, as well as the subsequent negative health effects. They found that the mother's parity (in "heifers" or first-time cow moms vs. older cows) and the need for colostrum intervention were the risk factors most likely to result in insufficient antibody protection....

Theia slammed into Earth, left marks and then formed the Moon, study suggests

Long ago, our solar system lost a planet. The planet, which scientists have since named Theia, found itself barreling uncontrollably toward a young Earth. The resulting impact destroyed Theia, turned Earth molten, and ultimately spun off some of the materials mixed between the two bodies into the Moon, which, by some estimates, formed in asContinue reading "Theia slammed into Earth, left marks and...
