Heading upriver
A river's only consistent attribute is change. As the Greek philosopher Heraclitus remarked, 'No man ever steps in the same river twice.' Although this dynamic nature is often out of sight and mind, forgetting about it has led to many a historical catastrophe. (2020-09-30)

Sea-level rise could make rivers more likely to jump course
A new study shows that sea level rise will cause rivers to change course more frequently. (2020-08-12)

Strangely ordinary strata
Researcher uncovers why most of the records left by ancient rivers preserve commonplace processes. (2020-06-16)

UCI scientists see order in complex patterns of river deltas
River deltas, with their intricate networks of waterways, coastal barrier islands, wetlands and estuaries, often appear to have been formed by random processes, but scientists at the University of California, Irvine and other institutions see order in the apparent chaos. (2017-10-18)

Transformations to granular zircon revealed: Meteor Crater, Arizona
Having been reported in lunar samples returned by Apollo astronauts, meteorites, impact glass, and at a number of meteorite craters on Earth, granular zircon is the most unusual and enigmatic type of zircon known. The mechanisms and transformations that form this distinctive granular zircon have, until now, remained speculative because it has not been produced in shock experiments. (2016-07-27)

Sudden shifts in the course of a river on a delta may be predicted, thanks to new study
Scientists studying deltas show how they may be able to predict where destructive changes in a river's course may occur. (2016-05-20)

Most herniated discs result from avulsion, not rupture, suggests study in spine
Herniated discs in the lower (lumbar) spine most often result from avulsion (separation) of the tissue connection between the disc and spinal bone, rather than rupture of the disc itself, according to a study in Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. (2013-08-14)

Cam-type deformities linked to MRI detected hip damage in asymptomatic young men
Hip impingement may be a risk factor of osteoarthritis of the hip. A new study reveals that the presence of an underlying deformity, known as cam impingement, is associated with hip damage in young men without any arthritis symptoms and detected using magnetic resonance imaging (MRI). Full findings are now published in Arthritis & Rheumatism, a journal of the American College of Rheumatology. (2011-09-08)

Catastrophic flooding may be more predictable after Penn researchers build a mini river delta
Researchers created a miniature river delta that replicates flooding patterns seen in natural rivers, resulting in a mathematical model capable of aiding in the prediction of the next catastrophic flood. (2010-03-16)
