Phys.org / Unexpected allies: DNA packaging aids gene expression
It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own version. Cornell researchers have discovered that DNA packaging structures called nucleosomes, ...
Phys.org / Phage-resistant bacteria can still sink carbon to ocean floor
Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but many operate in constant threat of being infected by viruses called phages, and mutate to fend ...
Phys.org / Sourdough starters: How flour choice shapes microbial communities
Sourdough starter, a fermented mix of flour and water, is a staple for bakers. It's also a rich experimental testing ground for microbiologists. The bread's chewy texture and tangy taste arise from the mix of microbes that ...
Phys.org / Nodding off is dangerous. Some animals have evolved extreme ways to sleep in precarious environments
Every animal with a brain needs sleep—and even a few without a brain do, too. Humans sleep, birds sleep, whales sleep and even jellyfish sleep.
Phys.org / Research reinvents MXene synthesis at a fraction of the cost
MXenes (pronounced like the name "Maxine") are a class of two-dimensional materials, first identified just 14 years ago, with remarkable potential for energy storage, catalysts, ultrastrong lightweight composites, and a variety ...
Medical Xpress / Cancer's hidden 'safety switch': Silencing TAK1 gene could boost immunotherapy performance
Australian researchers have discovered that the TAK1 gene helps cancer cells survive attack from the immune system, revealing a mechanism that may limit the effectiveness of immunotherapy treatments.
Phys.org / Femtosecond laser technique captures elusive atomic oxygen in water
A never-before-seen image of individual oxygen atoms dissolved in water has been captured.
Phys.org / High-energy photons drive conversion of greenhouse gases into high-value chemicals, no catalyst needed
Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful chemicals without any expensive catalysts, using only light.
Phys.org / Long-standing puzzle of the Sadovskii vortex pair solved after nearly a half-century
A team of researchers affiliated with UNIST has made a significant breakthrough by mathematically proving that a special type of vortex pair, called the Sadovskii vortex patch, can exist within ideal fluid flows. This marks ...
Phys.org / Kangaroos fix their posture to save energy at high hopping speeds, study shows
Researchers have taken a leap in understanding how kangaroos can increase their hopping speeds without incurring an associated energetic cost.
Phys.org / Nanoparticle vaccine strategy could protect against Ebola and other deadly filoviruses
Filoviruses get their name from the Latin word "filum," meaning thread—a reference to their long, filamentous shape. This virus family contains some of the most dangerous pathogens known to science, including Ebola, Sudan, ...
Medical Xpress / Exposure to common air pollutants alters adolescent brain development, study finds
Physician-scientists at Oregon Health & Science University warn that exposure to air pollution may have serious implications for a child's developing brain.
