Conquering traffic congestion with mathematics

A new collaborative engineering project funded by NSF aims to make numerical computation of departure rates and route choice faster, enabling rapid rerouting and diversion. The project uses machine learning to develop statistical models of traffic flow, potentially reducing congestion by seconds, minutes or hours ahead of time.

It's good to be rare, for some species

Researchers from UC Davis predict certain traits, such as internal fertilization and long-distance mating signals, can help rare species persist during crises. These traits may provide advantages for chronically rare species when compared to more common species that are likely to face extinction during great extinction events.

US provides most development assistance for health, but lags behind others in per person spending

A new study finds that while the US consistently provides more funding for development assistance for health than any other country, some high-income European nations have surpassed the US's assistance in per capita and expenditure measurements. The US ranking fifth at $714 contributed to DAH for every $1 million in national income.

Lightning, with a chance of antimatter

A team of Japanese researchers from Kyoto University used gamma-ray detectors to study the effects of lightning on atmospheric elements. They found that lightning emits positrons, a form of antimatter equivalent to electrons, through interactions with nitrogen and other elements in the atmosphere.

Man's earliest ancestors discovered in southern England

Fossils of the oldest mammals related to mankind have been discovered on the Jurassic Coast of Dorset, dating back 145 million years. The two teeth belong to small, rat-like creatures that lived during the time of the dinosaurs and are the earliest undisputed fossils of mammals belonging to the line that led to human beings.

Getting the world to listen

Researchers can increase their work's impact by using visual storytelling and developing a media product following a Four Phase Media Development Model. This model involves four steps: scoping, development, release, and review to ensure success.

UM scientist awarded grant aimed to increase aquaculture production in the US

University of Miami Professor Daniel Benetti has been awarded a $967,000 grant from NOAA to develop hatchery technology for three economically important marine fish species. The project aims to create an affordable supply of seed for commercial producers, relieving pressure on wild stocks without negative economic impacts.
