Study reveals an unprecedented change in Europe's fire regime      (via sciencedaily.com) 

A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.

Climate change will increase chances of wildfire globally -- but humans can still help reduce the risk      (via sciencedaily.com) 

New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.

Wildfires may have sparked ecosystem collapse during Earth's worst mass extinction      (via sciencedaily.com) 

New research reveals that wildfires may have been a key contributor to the total collapse of land ecosystems during Earth's worst mass extinction event over 250 million years ago.

Simultaneous extreme weather created dangerous cascades in U.S.      (via sciencedaily.com) 

Intense heat in the southwestern United States broke records last summer partly because it hit in tandem with an unusually severe drought, finds a new study measuring for the first time how the two extreme weather events dangerously interacted in real time.

Insight into past--and future--of Western US wildfires      (via sciencedaily.com) 

A new study examines the context surrounding the fires and offers insight into the historical role of large, high-severity fires -- and the future of wildfires -- west of the Cascades.

A new model sheds light on how we learn motor skills      (via sciencedaily.com) 

Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased variability in movements -- is important when learning a new task. These results may lead to improved motor rehabilitation in patients after injury or disease.

Wildfire smoke exposure negatively impacts dairy cow health      (via sciencedaily.com) 

Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western states, where wildfires are especially prevalent, are home to more than two million dairy cows that produce more than 25% of the nation's milk. A new report examines how dairy cattle in the Western United States may be affected by unique air pollutants from wildfire smoke.

Earliest record of wildfires provide insights to Earth's past vegetation and oxygen levels      (via sciencedaily.com)     Original source 

While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth's systems without the influence of humans for hundreds of millions of years.

New, highly tunable composite materials--with a twist      (via sciencedaily.com) 

Mathematicians have found that they can design a range of composite materials from moiré patterns created by rotating and stretching one lattice relative to another. Their electrical and other physical properties can change --s ometimes quite abruptly, depending on whether the resulting moiré patterns are regularly repeating or non-repeating.

New fire shelter prototypes could buy time for wildfire firefighters      (via sciencedaily.com)     Original source 

Temperatures inside new wildfire shelter prototypes remained within survival limits for longer, and the shelters took longer to break open, compared with an industry standard.

Study explores the promises and pitfalls of evolutionary genomics      (via sciencedaily.com) 

A new study examines mathematical models designed to draw inferences about how evolution operates at the level of populations of organisms. The study concludes that such models must be constructed with the greatest care, avoiding unwarranted initial assumptions, weighing the quality of existing knowledge and remaining open to alternate explanations.

Agriculture tech use opens possibility of digital havoc      (via sciencedaily.com) 

Wide-ranging use of smart technologies is raising global agricultural production but international researchers warn this digital-age phenomenon could reap a crop of another kind -- cybersecurity attacks. Complex IT and math modelling has highlighted the risks.

AI reveals unsuspected math underlying search for exoplanets      (via sciencedaily.com) 

The astronomers' goal: find an artificial intelligence algorithm to interpret microlensing events captured by the upcoming Roman Space Telescope and speed detection of exoplanets around other stars. They achieved that, but the AI told them something unexpected and deep: the theory used to infer stellar and exoplanetary masses and orbits from observations was incomplete. Digging into the mathematics, they uncovered a theory that explains all types of microlensing events and possible ambiguities in interpreting them.

The numbers don't lie: Australia is failing at maths and we need to find a new formula to arrest the decline      (via sciencedaily.com) 

Australia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide.

An easier way to teach robots new skills      (via sciencedaily.com) 

Researchers have developed a technique that enables a robot to learn a new pick-and-place task with only a handful of human demonstrations. This could allow a human to reprogram a robot to grasp never-before-seen objects, presented in random poses, in about 15 minutes.

Study shows simple, computationally-light model can simulate complex brain cell responses      (via sciencedaily.com) 

Studying how brain cells respond to signals from their neighbors can aid the understanding of cognition and development. However, experimentally measuring the brain's activity is complicated. Neuron models provide a non-invasive way to investigate the brain, but most existing models are either computationally intensive or cannot model complex neuronal responses. Recently, a team has used a computationally simple neuron model to simulate some of the complex responses of neurons.
