Yale study: Doctors give electronic health records an 'F'
The transition to electronic health records (EHRs) was supposed to improve the quality and efficiency of healthcare for doctors and patients alike — but these technologies get an 'F' rating for usability from health care professionals, and may be contributing to high rates of professional burnout, according to a new Yale-led study.

Buckyballs in space may come from dying stars
New research may explain how "buckyballs"—complex carbon molecules with a soccer-ball-like structure—form in space. Carbon 60, or C60 for short, (the official name is Buckminsterfullerene) comes in spherical molecules consisting of 60 carbon atoms organized in five-membered and six-membered rings. The name "buckyball" derives from their resemblance to the architectural work of Richard Buckminster

How to make better biofuels? Convince yeast it's not starving
Yeast already helps make bread and beer and cranks out the biofuel ethanol, but scientists believe it can be used to create an even more efficient fuel called isobutanol. Normally, yeast only creates a tiny amount of isobutanol. Now researchers at Princeton University have discovered a genetic switch that significantly ramps up production.

The team distributed the problem in such a way that the algorithm reached a performance of less than 15 seconds of wall-clock time per time step for more than 6 trillion grid points–a new world record surpassing the prior state of the art in the field for the size

NASA's Terra satellite sees fire and smoke from devastating bushfires in Australia
The state of New South Wales (NSW) in south eastern Australia is continuing to experience devastating bushfires due to the dry tinder-like atmosphere in the territory: high winds, dry lightning and continuing heat. Approximately 69 fires are still raging in NSW according to its Facebook page and more than 70 are burning to the south in Queensland. And the summer has just begun in the region.

Diet trials often amend their outcome measures as they go
A study published today in JAMA Network Open concludes that 86 percent of diet trials amended their desired study outcomes along the way. That raises the possibility of bias, say researchers David Ludwig, MD, PhD and Cara Ebbeling, PhD, of Boston Children's Hospital, and Steven Heymsfield, MD, of the Pennington Biomedical Research Center (Baton Rouge, Louisiana).

Mechanical signaling cascade central to fibrotic scar tissue development defined
In a new study published in Science Signaling, Cleveland Clinic researchers have identified a novel target for new therapies that may help to treat or prevent a host of fibrotic conditions, which contribute to nearly half of overall mortality in the United States.

85% of Venice underwater after worst flooding in 50 years
About 85 percent of Venice was underwater on Tuesday, with water levels reaching more than six feet deep at some points. Venice's mayor said the unusually strong flooding was caused by climate change, estimating the damage to be in the hundreds of millions of Euros. Venice's MOSE engineering project aims to protect Venice from rising seas, but some say it won't help the city stay above water. Non

Mysteries behind interstellar buckyballs finally answered
Scientists have long been puzzled by the existence of so-called "buckyballs"—complex carbon molecules with a soccer-ball-like structure—throughout interstellar space. Now, a team of researchers from the University of Arizona has proposed a mechanism for their formation in a study published in the Astrophysical Journal Letters.

When reporting climate-driven human migration, place matters
A quick Google search for "What is driving migration from Central America?" reveals that nearly all of the top hits claim climate change as a major catalyst for the mass movement of people out of their home countries. University of Arizona climate researchers, however, have shown that the reality is much more nuanced.

Early spinal patterns may predict scoliosis in teen years
A pediatric researcher has identified patterns of spinal curvature in younger children that may be likely to develop into scoliosis by adolescence. Accurately predicting scoliosis, a common, abnormal curvature of the spine, may set the stage for the first-ever methods to prevent the potentially disabling condition.

People who cannot read may be three times as likely to develop dementia
New research has found that people who are illiterate, meaning they never learned to read or write, may have nearly three times greater risk of developing dementia than people who can read and write. The study is published in the Nov. 13, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Chitin-binding proteins override host plant's resistance to fungal infection
A recent article studies chitin-binding proteins from a soilborne fungus (Verticillium nonalfalfae) that causes vascular wilt in plants. This fungus binds a particular protein (VnaChtBP) to chitin in order to abolish the host plant's chitin-triggered burst of reactive oxygen species and shield the fungus from being digested by the plant.

New artificial intelligence system automatically evolves to evade internet censorship
Researchers developed a tool called Geneva (short for Genetic Evasion), which automatically learns to circumvent censorship. Tested in China, India and Kazakhstan, Geneva found dozens of ways to circumvent censorship by exploiting gaps in censors' logic and finding bugs that the researchers say would have been virtually impossible to find manually.

How the cellular recycling system is put on hold while cells divide
Research involving several teams has shown that cellular recycling (autophagy) is repressed during the process of cell division, and how repression of autophagy during mitosis utilizes a different master regulator. The findings address a long-standing point of contention in biology.
