3D printing has driven innovations in fields ranging from art to aerospace to medicine. However, the high-energy ultraviolet (UV) light used in most 3D printers to cure liquid resins into solid objects limits the technique's applications. Visible-light curing, which would be more appropriate for some uses, such as tissue engineering and soft robotics, is slow. Now, researchers reporting in ACS Central Science have developed photopolymer resins that boost the speed of visible-light curing.
E-cigarette, or vaping, associated lung injury (EVALI) has sickened thousands of people, most under the age of 35. Studies have linked vitamin E acetate, an oily substance in some vaping liquids, to the disorder. Now, researchers reporting in ACS' Chemical Research in Toxicology have uncovered a possible mechanism: Vitamin E acetate could increase the fluidity of lung surfactant, causing the surfactant layer to collapse, contributing to symptoms such as shortness of breath and lung inflammation.
The most basic activity of a living thing is to turn one copy of its genome into two copies, crafting one cell into two. That replication event begins with a set of proteins--the Origin Recognition Complex (ORC). And, with some cancers and developmental diseases linked to ORC proteins, structural biologists need to see how the complex works so they can understand how it might go wrong.
Higher viral loads are associated with a greater risk of death among cancer and non-cancer patients hospitalized with coronavirus disease 2019 (COVID-19), researchers report September 15 in the journal Cancer Cell. Among hospitalized COVID-19 patients, those with hematologic malignancies who had recently been treated for cancer had the highest levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19.
The culture of science is changing. Researchers are examining the methods and practices that have long been the basis for scientific research and publication with the goal of improving it. This "moment of change," the authors of a new paper write, presents an opportunity to address science's "historic lack of diversity and noninclusive culture."
UTICA, NY -- Researchers from the Masonic Medical Research Institute (MMRI), the Precision Cardiology Lab (PCL) of the Broad Institute at MIT and Harvard, Bayer USA, Massachusetts General Hospital, and University of Pennsylvania collaborated to uncover some pressing questions about the biology of the heart. While understanding the mechanisms causal to human heart disease remain active areas of research for many scientists, important knowledge gaps about its composition and function remain unknown.
ITHACA, N.Y. - When stars like our sun die, all that remains is an exposed core - a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.
In a study published in the Astrophysical Journal Letters, they show how NASA's upcoming James Webb Space Telescope could find signatures of life on Earth-like planets orbiting white dwarfs.
New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.
The findings, published today in Nature, show that a gene family only found in vertebrates is critical for forming the head skeleton and other traits unique to them during embryonic development.
WASHINGTON -- Researchers have developed an advanced spectrometer that can acquire data with exceptionally high speed. The new spectrometer could be useful for a variety of applications including remote sensing, real-time biological imaging and machine vision.
Spectrometers measure the color of light absorbed or emitted from a substance. However, using such systems for complex and detailed measurement typically requires long data acquisition times.
An international collaboration between researchers at Queen Mary University of London and the Chinese Academy of Science in Nanjing has led to the discovery of world's oldest animal sperm inside a tiny crustacean trapped in amber around 100 million years ago in Myanmar.
The research team, led by Dr He Wang of the Chinese Academy of Science in Nanjing, found the sperm in a new species of crustacean they named Myanmarcypris hui. They predict that the animals had sex just before their entrapment in the piece of amber (tree resin), which formed in the Cretaceous period.
Tortoises are born with a natural preference for faces, according to new research from scientists at Queen Mary University of London, the University of Trento and the Fondazione Museo Civico Rovereto.
The study provides the first evidence of the tendency for solitary animals to approach face-like shapes at the beginning of life, a preference only previously observed in social species such as human babies, chicks and monkeys.
Artificial intelligence researchers at North Carolina State University have improved the performance of deep neural networks by combining feature normalization and feature attention modules into a single module that they call attentive normalization (AN). The hybrid module improves the accuracy of the system significantly, while using negligible extra computational power.
In the first research of its kind, a new University of California, Davis, study suggests that for the most part, people formulate goals consistent with their personality traits -- and an individual's goals are related to how their personality subsequently changes over time.
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging.
Tropical Storm Karina was making night moves like the old Bob Seger song. NASA-NOAA's Suomi NPP satellite provided an infrared image of Tropical Storm Karina's nighttime movement as it moved away from the Baja California peninsula of Mexico. Infrared data showed the storm was weakening.
