Biomechanical model could reduce wobbling of pedestrian bridges
The dangerous wobbling of pedestrian bridges could be reduced by using biomechanically inspired models of pedestrian response to bridge motion and a mathematical formula to estimate the critical crowd size at which bridge wobbling begins, according to a study led by Georgia State University.

Researchers identify how bacterium survives in oxygen-poor environments
Columbia University biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell. The finding could explain how some bacteria, such as Pseudomonas aeruginosa (P. aeruginosa), are able to thrive in oxygen-poor environments like biofilms and resist antibiotics. P. aeruginosa biofilm infections are a leading cause of death for people suffering from cystic fibrosis, a genetic condition that affects the lungs and the digestive system.

UCLA engineers use deep learning to reconstruct holograms and improve optical microscopy
UCLA researchers report that they have developed new uses for deep learning: reconstructing a hologram to form a microscopic image of an object and improving optical microscopy. Their new holographic imaging technique produces better images than current methods that use multiple holograms, and it's easier to implement because it requires fewer measurements and performs computations faster.

Watching atoms move in hybrid perovskite crystals reveals clues to improving solar cells
The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers led by the University of California San Diego discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.

'Brazil nut effect' helps explain how rivers resist erosion, Penn team finds
In a new study, geophysicists from the University of Pennsylvania found that granular segregation helps explain the tendency of riverbeds to be lined by, or 'armored' with, a layer of relatively larger particles.

MIT physicists design $100 handheld muon detector
Physicists at MIT have designed a pocket-sized cosmic ray muon detector to track these ghostly particles. The detector can be made with common electrical parts, and when turned on, it lights up and counts each time a muon passes through. The relatively simple device costs just $100 to build, making it the most affordable muon detector available today.

Seafloor sediments appear to enhance Earthquake and Tsunami danger in Pacific Northwest
The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the geological record, the region is due for its next 'big one.' A new study led by The University of Texas at Austin has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone.

First known interstellar visitor is an 'oddball'
Gemini Observatory provided key observations in characterizing an object visiting from outside our solar system, 'Oumuamua. After the object was discovered by Pan-STARRS1 on Haleakala, both Gemini telescopes dropped everything to observe 'Oumuamua for three nights as it quickly dimmed from view. Researchers found that despite its interstellar origin, the object is similar in composition to some objects in our Solar System but its shape is unlike anything found around our Sun.

Chimp females who leave home postpone parenthood
Female chimps that lack supportive friends and family wait longer to start having babies, Duke University researchers find. An analysis of more than 50 years' worth of daily records for female chimpanzees in Gombe National Park in Tanzania indicates that would-be moms who leave home or are orphaned take roughly three years longer to start a family.

A curious quirk brings organic diode lasers one step closer
Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers use inorganic semiconductors grown in elaborate high vacuum systems. Now, a team of researchers from Penn State and Princeton University have taken a big step toward creating a diode laser from a hybrid organic-inorganic material that can be deposited from solution on a laboratory benchtop.

A team of researchers, including a faculty member and postdoctoral fellow from Washington University in St. Louis, found that oxygen levels appear to increase by roughly 80 percent at about the same time as a three-fold increase in biodiversity during the Ordovician Period, between 445 and 485 million years ago, according to a study published Nov. 20 in Nature Geoscience.

Brain activity buffers against worsening anxiety
Boosting activity in brain areas related to thinking and problem-solving may also protect against worsening anxiety, suggests a new study by Duke University scientists. Using noninvasive brain imaging, the researchers found that at-risk people were less likely to develop anxiety if they had higher activity in a region of the brain responsible for complex mental operations. The results may be a step towards tailoring psychological therapies to the specific brain functioning of individual patients.
