Scientists reveal how light behaves in formless solids
For a long time, it was thought that amorphous solids do not selectively absorb light because of their disordered atomic structure. However, a new uOttawa study disproves this theory and shows that amorphous solids actually exhibit dichroism, meaning.....»»
Novel non-destructive inspection technique reconstructs inner hidden composition and structure of inspection targets
A research group at Chuo University, Japan, led by Assistant Professor Kou Li (Faculty of Science and Engineering), in collaboration with National Institute of Informatics, have developed a novel non-destructive inspection technique by effectively co.....»»
New tool helps decipher gene behavior
Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact with diseases. This research has partly focused on 'epigen.....»»
An 80-mph speed record for glacier fracture helps reveal the physics of ice sheet collapse
There's enough water frozen in Greenland and Antarctic glaciers that if they melted, global seas would rise by many feet. What will happen to these glaciers over the coming decades is the biggest unknown in the future of rising seas, partly because g.....»»
Double trouble at chromosome ends: New study alters our understanding of telomere biology
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres that protect the ends of chromosomes should have be.....»»
Nvidia is the ‘GPU cartel,’ says former AMD Radeon manager
The former head of AMD graphics has come out with some strong words against Nvidia, calling the mammoth GPU company the GPU cartel......»»
Enhancing electrogenerated chemiluminescence of an iridium complex
Electrogenerated chemiluminescence (ECL) cells, characterized by their self-emissive nature, have gathered significant interest for prospective display applications due to their uncomplicated structure and straightforward fabrication process. These c.....»»
Tattoo inks found to not match the ingredients listed on the bottle
When you get a tattoo, do you know what you're putting under your skin? According to new Binghamton University research, the ingredient labels on tattoo ink don't match the actual substances in the bottle......»»
A new theoretical development clarifies water"s electronic structure
There is no doubt that water is significant. Without it, life would never have begun, let alone continue today—not to mention its role in the environment itself, with oceans covering over 70% of Earth......»»
Observations explore radio jet of a powerful quasar
European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties of this jet, sugges.....»»

Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds
A new technique for electrospinning sponges has allowed scientists from the University of Surrey to directly produce 3D scaffolds—on which skin grafts could be grown from the patient's own skin......»»
How to track important changes in a dynamic network
Networks can represent changing systems, like the spread of an epidemic or the growth of groups in a population of people. But the structure of these networks can change, too, as links appear or vanish over time. To better understand these changes, r.....»»
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Elec.....»»
How colourism affects families in the UK—and how positive parenting can challenge it
Actor Lupita Nyong'o describes colourism as "the daughter of racism" in "a world that rewards lighter skin over darker skin". This form of prejudice sees people more penalized the darker their skin is and the further their features are from those ass.....»»
