Medical Xpress / Silencing stress signals could pave the way to a longer life
Silencing a major cellular stress signal could be the key to a longer life, according to new University of Sheffield research. While previous studies suggested that mild stress might help organisms live longer, new research ...
Tech Xplore / Overlooked 'in-between' materials could reshape solar fuel and battery design
Researchers have identified previously unknown materials, including a new form of a widely studied clean-energy material, by carefully controlling and tracking how molecular precursors break down during heating.
Phys.org / A new way to plan trajectories to asteroids
There are tens of thousands of near-Earth objects (NEOs) that represent some of the most easily accessible resources in the solar system. Planning trajectories to rendezvous with these miniature worlds is notoriously difficult, ...
Phys.org / Drone radar reveals buried glaciers on Earth, guiding the search for water on Mars
Understanding how to explore hidden glaciers on Mars begins not in a laboratory, but in remote field camps across Alaska and Wyoming.
Medical Xpress / Host genetics and sex can steer flu toward greater virulence, mouse experiments reveal
During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, rather than to evade the host's immune system. The genetics and sex of the host influence how a novel ...
Phys.org / Studying the emergence of leaders in moving crowds of pedestrians
When humans are moving as a crowd, their movements tend to be highly coordinated, similarly to the collective motions of bird flocks or other groups of animals. These group behaviors can limit collisions in dynamic environments, ...
Phys.org / Captured mid-reaction, RNA polymerase reveals universal blueprint for gene transcription
The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and a process fundamental to all life. But the inner workings of this essential enzyme have long baffled ...
Phys.org / Archaeologists at Pompeii use AI to reconstruct the face of a man killed in the volcano's eruption
Archaeologists and researchers at the ancient Roman site of Pompeii have used artificial intelligence for the first time to digitally reconstruct the face of a man killed in the AD 79 eruption of Mount Vesuvius that smothered ...
Phys.org / Hidden 3D atomic structure of relaxor ferroelectrics revealed for first time
Materials called relaxor ferroelectrics have been used for decades in technologies like ultrasounds, microphones, and sonar systems. Their unique properties come from their atomic structure, but that structure has stubbornly ...
Medical Xpress / Severe narcolepsy found to damage a second brain region
For nearly 25 years, scientists believed they knew what caused the most severe form of narcolepsy. A new UCLA Health study now suggests they were only half correct. In a study published in Nature Communications, UCLA Health ...
Phys.org / Western US is fending off more fires before they start—and still getting hit by its biggest blazes yet
The number of wildfires burning in the Western United States each year dropped roughly 28% over the past three decades, even as annual burned area and damage from wildfires have soared. A decline in fires accidentally sparked ...
Tech Xplore / Ultralight carbon fiber lattices achieve aluminum-level performance at a fraction of the weight
Researchers at Seoul National University have developed a new class of ultralight structural materials that combine the load-bearing strength of engineering materials with the weight of foam. Using a method called 3D node ...
