Heat Waves Can Buckle Train Tracks, Delaying Commutes and Commerce
Extreme heat can cause train tracks to expand and buckle. That’s forcing rail operators to adapt as the climate warms.....»»
New electron microscopy technique reveals complex spin structures at femtosecond timescales
Plasmons are collective oscillations of electrons in a solid and are important for a wide range of applications, such as sensing, catalysis, and light harvesting. Plasmonic waves that travel along the surface of a metal, called surface plasmon polari.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»
Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging objects such as black hol.....»»
Plasma heating efficiency in fusion devices boosted by metal screens
Heating plasma to the ultra-high temperatures needed for fusion reactions requires more than turning the dial on a thermostat. Scientists consider multiple methods, one of which involves injecting electromagnetic waves into the plasma, the same proce.....»»
More than 1,300 Hajj pilgrims died this year when humidity and heat pushed past survivable limits—it"s just the start

Prototype sunscreen uses TiO₂ nanoparticles to cool skin while blocking UV rays
Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV light and heat from the sun using radiative cooling......»»
NASA payload aims to probe moon"s depths to study heat flow
Earth's nearest neighboring body in the solar system is its moon, yet to date, humans have physically explored just 5% of its surface. It wasn't until 2023—building on Apollo-era data and more detailed studies made in 2011–2012 by NASA's automate.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
Storm fears overshadow India coast decades after tsunami
The deadly tsunami that swamped India's southern coast two decades ago was a one-off disaster, but storms that are growing ever more intense spark panic each time howling gales whip up waves......»»
Aerosols could be weakening summertime circulation in the Northern Hemisphere
Over the past several decades, summer jet streams (or west to east wind flow) and weather systems in the Northern Hemisphere have weakened. Projections suggest the trend will continue, which could make extreme heat events more likely and affect air q.....»»

Rising drought frequency poses new threats to US wildlife, study finds
People around the world are dealing with drought, so it's not shocking that it affects wildlife, too: lack of moisture contributes to habitat loss, affects how animals compete for resources, and leads to dehydration and heat stress. The surprising pa.....»»
Scientists struggle to explain record surge in global heat
The world has been getting hotter for decades but a sudden and extraordinary surge in heat has sent the climate deeper into uncharted territory—and scientists are still trying to figure out why......»»
Surveys show full scale of massive seabird die-off due to Pacific Ocean heat wave
Murres, a common seabird, look a little like flying penguins. These stout, tuxedo-styled birds dive and swim in the ocean to eat small fish and then fly back to islands or coastal cliffs where they nest in large colonies. But their hardy physiques di.....»»
