Frozen mammoth skin retained its chromosome structure
Features as small as 50 nanometers preserved in a 50,000-year-old sample. Enlarge (credit: LEONELLO CALVETTI/SCIENCE PHOTO LIBRARY) One of the challenges of working with ancient DNA samples is that damage accumulates ove.....»»
Physicists reveal evolution of shell structure using machine learning
A research team has used a machine learning approach to investigate the evolution of shell structure for nuclei far from the stability valley. The study, published in Physics Letters B and conducted by researchers from the Institute of Modern Physics.....»»
New method improves understanding of light-wave propagation in anisotropic materials
Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional differences in how they scatter light, known as anisotrop.....»»
Bridging large riverine ecosystems for inter-basin exchanges
Many of the world's large rivers have been modified to support food security, hydropower production, navigation and trade. While these developments are necessary to support a growing human population, they also pose substantial risks to the structure.....»»
Mice made transparent with a dye used in Doritos
Matching refractive indexes lets some wavelengths pass cleanly through the skin. Enlarge / Zihao Ou, who helped develop this solution, holds a tube of it. One key challenge in medical imaging is to look past skin and ot.....»»
Are white patches on whale shark skin cause for concern?
Marine scientists have been taking samples from whale shark skin to try and determine the effect of pollutants on whale health......»»
Research team uses terahertz pulses of light to shed light on superconducting disorder
A team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, Germany, and Brookhaven National Laboratory in the United States has demonstrated a new way to study disorder in superconductors using ter.....»»
Study shows urbanization has impacted the population genetic structure of the Eurasian red squirrel in Japan
Since many kinds of wildlife have started living in urban environments, urban environments have been recognized as places of biodiversity conservation. What kind of factors facilitate or prohibit wildlife from living in urban environments?.....»»
Researchers simulate novel metal-filtered VCSEL modal control
A study led by researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences revealed a novel metal-dielectric film mode filter structure that can flexibly regulate transverse modes in vertical-cavi.....»»
Researchers solve long-standing mystery of alumina surface structure
Aluminum oxide (Al2O3), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide range of applications: in electronic components, as a support material for catalysts, or as a chemically resistant ceramic, to na.....»»
NMR spectroscopy method provides faster way to determine chiral structure of molecules
Researchers from Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH have developed a new method that allows, for the first time, the elucidation of the chiral structure of molecules—the exact spatial arrangement of the atoms—by nuclear ma.....»»
Archaeologists suggest Neolithic Scandinavians may have used skin boats to hunt, travel and trade
Recent research by Dr. Mikael Fauvelle and his colleagues, published in the Journal of Maritime Archaeology, proposes that the neolithic Pitted Ware Culture (PWC) may have used skin boats to conduct trade, travel, fishing, and hunting activities......»»
Destiny 2 moving to two smaller expansions per year instead of one big one
Bungie is making some big changes to Destiny 2, including its release structure and how expansions will play out......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»
Crystallized alternative DNA structure sheds light on insulin and diabetes
The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team......»»
A window into the body: New technique makes skin invisible
Researchers have developed a new way to see organs within a body by rendering overlying tissues transparent to visible light. The counterintuitive process—a topical application of food-safe dye—was reversible in tests with animal subjects, and ma.....»»
How fish guts might play a role in future skin care products
There are some pretty strange ingredients in cosmetics and skin care products. One example is snail mucin—also known as snail slime—which is used for its moisturizing and antioxidant properties. But researchers reporting in ACS Omega might have f.....»»
Algorithm maps protein degradation patterns to improve infection diagnosis and treatment
Peptides are small fragments of proteins, mainly found in the skin and mucous membranes. Some peptides act as a barrier, protecting the body against infections by fighting off microorganisms like bacteria, viruses, and other pathogens, while others p.....»»
Researchers find genetic variant for speed of hair graying, susceptibility to skin melanoma in horses
Graying with age is a common coat color variant in horses, characterized by progressive hair graying and susceptibility to skin melanoma. In a new study published in Nature Communications, an international consortium led by scientists from Uppsala Un.....»»
Assorted, distinctive behavior of molten uranium salt revealed by neutrons
In a paper published in the Journal of the American Chemical Society, researchers have documented for the first time the unique chemistry dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt, a potential nuclear fuel sour.....»»
Color-changing, self-healing hydrogel microparticles: A smart solution for advanced wound care
