Phys.org / A painting signed 'L daVinci': Analysis reveals Renaissance pigments and later alterations
Researchers at Uppsala University have analyzed the color pigments in a historical painting signed "L daVinci." Most of the pigments are consistent with materials used during the Renaissance, while a more recent pigment appears ...
Medical Xpress / Fecal microbiota transplantation may improve immunotherapy-related colitis
Targeting the gut microbiome with fecal microbiota transplantation (FMT) may help cancer patients with immunotherapy-related colitis avoid the need for steroids and other immunosuppressive treatments, according to researchers ...
Phys.org / How advertising turns our insecurities into profit—and how you can resist the manipulation
Have you ever bought something not because you wanted it, but because you were afraid of what might happen if you didn't? Maybe you worried about looking older, falling behind at work or simply not fitting in.
Phys.org / Peptide position determines whether gold nanoparticles branch or stay spherical
The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from the Institute of Science Tokyo. Peptides localized at the membrane interface promote branched ...
Phys.org / Three DNA loops prove essential for efficient wing tissue regeneration in fruit flies
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act ...
Phys.org / Advanced X-ray crystallography determines structure of macromolecule at unprecedented resolution
Proteins are high-performance molecular machines that carry out nearly every biochemical function inside living cells. To understand how they achieve this, scientists often examine their detailed atomic structure, which holds ...
Phys.org / Cancer-linked protein binds to chromosome in unexpected way, study finds
A new 3D structure of a cancer-linked protein bound to its cellular partner reveals details of how the protein binds to chromosomes and could offer insights for future disease treatments. The protein—BRD4—plays a critical ...
Tech Xplore / What if you only see part of a network? And how do you spot meaningful connections?
From friendship networks and the internet to connections in the brain and trade relationships between countries, networks are everywhere. Physicists at Leiden study the fundamental principles underlying all these networks, ...
Tech Xplore / 'Hardflow' algorithm could help generative AI produce high-quality outputs that obey strict requirements
MIT researchers have developed a new technique that helps generative artificial intelligence models find solutions to high-stakes problems. In these settings, a plausible answer is not enough: The output often must also satisfy ...
Phys.org / Common wastewater pollutant turns male minnows into poorer parents and fiercer rivals
A team of researchers has found that a common wastewater pollutant turned male fathead minnows into worse fathers and fiercer rivals, revealing ecological impacts that laboratory studies missed.
Tech Xplore / Periodic voltage fluctuations can 'see' inside lithium batteries, no disassembly required
Monitoring the lifespan of a lithium-ion battery without disassembling it may be possible. This prospect emerged from a study published in May in the journal Cell Reports Physical Science by researchers at the State University ...
Medical Xpress / Iron overload: How tea, coffee, red meat and alcohol can affect absorption
Most of us are used to hearing about the risks of not getting enough iron. Yet having too much iron in the body can also cause serious health problems.
