Study maps four flood model types and urges hybrid approaches to improve forecasts‎

Before rain begins to fall, scientists and engineers can predict where a storm might cause flooding thanks to advanced modeling and digital simulations that help guide billion-dollar decisions involving infrastructure design, emergency response, land-use planning, insurance, agriculture, water quality, and public safety.

Fortified salad packs a healthy punch to meet a growing vitamin B12 need‎

A pioneering research-industry partnership has used advances in indoor farming technology to grow pea shoots fortified with vitamin B12, opening an exciting route to market for farmers and addressing a major public health need. The partnership between the John Innes Centre and the Quadram Institute, based at the Norwich Research Park, the University of Bristol, and indoor farm specialists LettUs Grow, harnessed the latest aeroponic techniques to successfully deliver the recommended daily allowance (RDA) of vitamin B12 within a 15-gram portion of pea shoots.

Failed experiment leads to surprise drug development breakthrough‎

Scientists at the University of Cambridge have developed a new way to alter complex drug molecules using light rather than toxic chemicals—a discovery that could accelerate and improve how medicines are designed and made. Published in Nature Synthesis, the study introduces what the team calls an "anti-Friedel–Crafts" reaction.

Caught but not eaten: Smaller insects more likely to escape catfish mouths‎

A Kobe University study shows that small aquatic beetles survive catfish attacks by resisting ingestion inside the catfish's mouth and being spat out alive. This research contributes to a deeper understanding of size-dependent predator-prey relationships in aquatic insects and fish.

We are not alone: Our sun escaped together with stellar 'twins' from galaxy center‎

Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an unprecedentedly accurate catalog of stars and their properties using data from the European Space Agency's Gaia satellite. Their discovery sheds light on the evolution of our galaxy, particularly the development of the rotating bar-like structure at its center.

Meet Crocodylus lucivenator, a 12- to 15-foot predator that hunted iconic Lucy's species‎

More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in rivers and lakes to attack them. According to a research team led by the University of Iowa, that crocodile is a new species.

Your cat is likely to live longer if you don't let them roam—new study‎

We all know cats represent a major threat to native animals and birds. Australia's 5.3 million domestic cats kill a total of 546 million animals each year in Australia. What's less well known is allowing your domestic cat to roam outside exposes them to considerable danger—and the risk of a short life.

What's it like to be a bat? Scientists develop new solution to the puzzle of animal minds‎

In 1974, philosopher Thomas Nagel posed a deceptively simple question: "What is it like to be a bat?" His point wasn't really about bats. He was offering a provocative challenge about the limits of understanding another mind: no matter how much we try, we cannot access what it feels like to experience the world as another.
