The largest earthquake sequence in Southern California in two decades has taught scientists that large earthquakes can occur in a more complex fashion than commonly assumed. The sequence also loaded up strain on a nearby major fault, according to a new study.

Objects can be continuously printed from a vat of photocurable resin at rates exceeding 430 millimeters per hour, thanks to a new approach to rapid and large-scale stereolithographic 3d printing (SLA). The method overcomes the challenges imposed by heat buildup from curing resin, which has limited the capabilities of previous iterations of continuous SLA 3d printing. Stereolithographic printing is a widely used method in commercial 3d printing. It relies on UV light to harden photoreactive resins into complex 3d shapes.

COLUMBUS, Ohio - Organic chemists at The Ohio State University have figured out how to synthesize the most common molecule arrangement in medicine, a scientific discovery that could change the way a number of drugs - including one most commonly used to treat ovarian cancer - are produced.

Their discovery, published today in the journal Chem, gives drug makers a crucial building block for creating medicines that, so far, are made with complex processes that result in a lot of waste.

St. Paul, MN (October, 2019)--In August 2017, Kathy S. Lawrence, a plant pathologist at Auburn University, received a call from Drew Schrimsher of Agri-AFC, who had discovered foliar distortion and leaf curling and rolling on approximately 50,000 acres of cotton in southeastern Alabama. After ruling out herbicide damage, Schrimsher contacted Lawrence, and she visited the fields 2 days later.

AMHERST, Mass. - There are an estimated 20,000 to 30,000 proteins at work in cells, where they carry out numerable functions, says computational molecular biologist Roman Sloutsky at the University of Massachusetts Amherst. "One of the central questions in all of biochemistry and molecular biology," he adds, is how their precisely-tuned functions are determined.

Scientists with the Smithsonian's National Museum of Natural History and collaborators surveying the birdlife of Borneo have discovered a startling surprise: an undescribed species of bird, which has been named the Spectacled Flowerpecker. While scientists and birdwatchers have previously glimpsed the small, gray bird in lowland forests around the island, the Smithsonian team is the first to capture and study it, resulting in its formal scientific description as a new species.

Cold Spring Harbor Laboratory Professor Anthony Zador has taken the next step in his quest to solve exactly how the brain is wired.

Ultrashort laser pulses have enabled scientists and physicians to carry out high-precision material analyses and medical procedures. Physicists from the Universities of Bayreuth and Göttingen have now discovered a new method for adjusting the extremely short time intervals between laser flashes with exceptional speed and precision. The intervals can be increased or decreased as needed, all at the push of a button. Potential applications range from laser spectroscopy to microscopy and materials processing. The results were published in Nature Photonics.

The Yellowstone National Park in the USA with its geysers and hot springs is a great attraction for tourists. However, especially in times of little news, the media often focusses on the Yellowstone Supervolcano, which last erupted about 630,000 years ago. Inevitably, then the question of the underlying geological structures will be posed. A recent study by Bernhard Steinberger of the German GeoForschungsZentrum and colleagues in the USA helps to better understand the processes in the Earth's interior.

One of the tasks of the scientists work is to explain how the world functions. Their research ideas often seem being unrealistic but, as it turns out, their research may truly help a great many of us. This is the case with the research work of Dr. Piotr Pieta's team at the IPC PAS. He has shown how the size of the molecules of beta-amyloid - a compound considered to be the 'culprit' in Alzheimer's disease - influences the way these molecules interact with cell membranes.

The roots of plants can do a lot of things: They grow in length to reach water, they can bend to circumvent stones, and they form fine root hairs enabling them to absorb more nutrients from the soil. A team of researchers led by scientists at the Technical University of Munich (TUM) has now identified an important regulator of this process.

New Rochelle, NY, October 17, 2019-Researchers have reported for the first time producing feline induced pluripotent stem cells (fiPSCs) from adult cells of domestic cats. The methods and implications of this research are published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

HARRISBURG, Pa. -- That pint of ice cream after a nasty breakup may not do as much damage as you think. Despite the emotional turmoil, people on average do not report gaining weight after a relationship dissolution, according to new research.

The study, which included researchers from Penn State, were investigating the German concept of "kummerspeck" -- excess weight gain due to emotional eating -- which literally translates to "grief bacon."

Fairfax, VA - Research by George Mason University College of Health and Human Services found that adults who likely had undiagnosed celiac disease (UCD) had lower bone density than the adults without UCD, although they consumed more calcium and phosphorous. Celiac disease is an autoimmune disease triggered by consuming gluten, and individuals with CD are often undiagnosed.
