Cooking up a new theory for better accelerators

While particle accelerators may be on the cutting edge of science, the building and preparation of some particle accelerator components has long been more of an art form, dependent on recipes born of trial and error. Now, Ari Deibert Palczewski hopes to change that. A staff scientist at the Department of Energy's Thomas Jefferson National Accelerator Facility, Palczewski has been awarded a DOE...

Contrast-enhanced ultrasound predicts nodule transformation to hepatocellular carcinoma

A new study has identified sonographic biomarkers that can predict eventual malignant transformation of pathologically confirmed cirrhotic nodules for patients at risk for hepatocellular carcinoma (HCC). These additional imaging features may have the potential to be adopted as ancillary or even major features to stratify probability for HCC in the contrast-enhanced LI-RADS system.

US corn yields get boost from a global warming 'hole'

The global average temperature has increased 1.4 degrees Fahrenheit over the last 100 years. In contrast, the Corn Belt of the U.S., one of the most agriculturally productive regions of the world, has experienced a decrease in temperatures in the summer during the growing season. Known as the "U.S. warming hole," this anomalous cooling phenomenon, which occurred in tandem with increasing rainfall,...

Schizophrenia risk gene linked to cognitive deficits in mice

Researchers have discovered in mice how one of the few genes definitively linked to schizophrenia, called SETD1A, likely confers risk for the illness. Mice genetically engineered to lack a functioning version of the enzyme-coding gene showed abnormalities in working memory, mimicking those commonly seen in patients. Restoring the gene's function corrected the working memory deficit and...

Why Saving the Oceans Is as Vital as Protecting Rain Forests

Saving the oceans is key to fighting the climate crisis, according to Ayana Elizabeth Johnson, a Brooklyn-born marine biologist and activist who is a rising figure in the climate movement.Johnson, 39, is the founder of Ocean Collectiv, a conservation consultancy, and of Urban Ocean Lab, a think tank, and speaks frequently at TED Talks, climate rallies and her salons at Pioneer Works in Brooklyn....

Vision scientists disprove 60-year-old perception theory

Vision researchers have disproved a long-standing theory of how the human vision system processes images, using computational models and human experiments. The findings could have implications for the understanding of human vision and diagnosis of vision anomalies.
