River research reveals scale of macroplastic pollution
Plastic pollution clogs river systems for considerably longer than previously thought, new research shows.  09/21/2021 05:27 PM

MIND diet linked to better cognitive performance
Researchers have found that older adults may benefit from a specific diet called the MIND diet even when they develop these protein deposits, known as amyloid plaques and tangles.  09/21/2021 05:27 PM

New machine learning method to analyze complex scientific data of proteins
Scientists have developed a method using machine learning to better analyze data from a powerful scientific tool: nuclear magnetic resonance (NMR). One way NMR data can be used is to understand proteins and chemical reactions in the human body. NMR is closely related to magnetic resonance imaging (MRI) for medical diagnosis.  09/21/2021 05:27 PM

Regulator proteins or symphonies of genes: Statistical modeling points way toward unified theory for DNA folding
Researchers seek to point a way toward a unified theory for how DNA changes shape when expressing genes. The scientists use an approach called statistical mechanics to explore the phenomenon of so-called expression waves of gene regulation. The group hopes to reconcile a long-standing gulf between the two scientific fields most involved in the topic, using concepts common to biology and physics.  09/21/2021 05:27 PM

Which types of brain activity support conscious experiences?
Our subjective experience appears to us in a continuous stream of integrated information, and researchers now explore the question: Which characteristics should brain activity have to support this type of conscious experiences? The group searched for integrated structures that encompass most of the brain but change configuration from time to time. Their hypothesis was these structures should vanish during states of deep unconsciousness, such as deep sleep or while under general anesthetics.  09/21/2021 05:27 PM

Carbon fibers electrical measurements pave way for lightning strike protection technologies
Carbon fiber reinforced polymer composite structures are important in several industries, yet the electrical behavior of a composite is challenging to measure or predict because of the electrical conductivity of constituent carbon fibers and the composite's complex hierarchical microstructure. Researchers report a direct measurement of the transverse electrical resistivity of a single carbon fiber. The researchers combined a precise sample preparation with a technique called the van der Pauw method to accomplish this challenging measurement.  09/21/2021 05:27 PM

Researchers build embryo-like structures from human stem cells
Researchers construct an embryo-like structure from human stem cells, resulting in a new way to study the earliest stages of development.  09/21/2021 05:27 PM

Researchers use exosome-based strategy to block HIV in mice
Researchers used exosomes, tiny nanoparticles capable of being taken up by cells, to deliver novel protein into the cells of mice infected with HIV. The protein attached to HIVs' genetic material and prevented it from replicating, resulting in reduced levels of HIV in the bone marrow, spleen, and brain. The study paves the way for the development of novel delivery systems for suppressing HIV.  09/21/2021 05:26 PM

Researchers study recurrent neural network structure in the brain
A recurrent neural network structure exists in the most important part of the brain -- the frontal cortex -- and this network is less complex than has been thought and mostly unidirectional, new research shows.  09/21/2021 05:26 PM

Four dinosaurs discovered in Montana, including a possible rare ostrich-mimic Anzu
A team of paleontologists excavated four dinosaurs in northeastern Montana this summer. The four dinosaur fossils are: the ilium -- or hip bones -- of an ostrich-sized theropod, the group of meat-eating, two-legged dinosaurs that includes Tyrannosaurus rex and raptors; the hips and legs of a duck-billed dinosaur; a pelvis, toe claw and limbs from another theropod that could be a rare ostrich-mimic Anzu, or possibly a new species; and a Triceratops specimen consisting of its skull and other fossilized bones.  09/21/2021 05:26 PM

Electrons on the edge: The story of an intrinsic magnetic topological insulator
An intrinsic magnetic topological insulator MnBi2Te4 has been discovered with a large band gap, making it a promising material platform for fabricating ultra-low-energy electronics and observing exotic quantum phenomena.  09/21/2021 05:26 PM

Is your child a fussy eater?
New research is providing a better understanding of what influences fussy eaters, and what is more likely to increase or decrease picky eating in children under 10.  09/21/2021 05:26 PM

Nasal drugs show promise for slowing Parkinson’s disease progression in lab study
Researchers have shown that two lab-developed and nasally-delivered peptides helped slow the spread of alpha-synuclein in mice. 'If these results can be replicated in patients, it would be a remarkable advance in the treatment of devastating neurological disorders,' says the lead author.  09/21/2021 05:18 PM

Engineering researchers develop new explanation for formation of vortices in 2D superfluid
Researchers have new insight about the formation of vortices in a type of quantum fluid, work that could help our comprehension of the physics mystery of how vortex clusters form and provide valuable understanding into the atmospheric swirling motion on planets such as Earth and Jupiter.  09/21/2021 03:42 PM

Roman-era mixers and millstones made with geology in mind
A study on stone tools from an outpost of the Roman Empire has found that for ancient bakers and millers, having the right tools was a matter of geology.  09/21/2021 02:01 PM

Our eyes and brain work together to create a ‘pipeline’ of meaning – new study
Humans read by 'pre-processing' written words to create a pipeline of meaning, according to new research.  09/21/2021 02:01 PM

Records from Lake Magadi, Kenya, suggest environmental variability driven by changes in Earth’s orbit
Rift Valley lakes within eastern Africa range from freshwater to highly alkaline systems and are homes to diverse ecosystems. These Rift Valley lakes are also sedimentary repositories, yielding a high-resolution environmental record that can be targeted to better understand the environmental and climatic context of human evolution over the past few million years in eastern Africa.  09/21/2021 01:43 PM

Novel method of bioprinting neuron cells
Researchers have developed a new method of bioprinting adult neuron cells. They're using a new laser-assisted technology that maintains high levels of cell viability and functionality.  09/21/2021 01:43 PM

'Beach ball' representations calculated for US underground nuclear tests can aid monitoring
Researchers have calculated moment tensors for 130 underground nuclear and 10 chemical test explosions that took place at the Nevada National Security test site.  09/21/2021 01:43 PM

Darwin’s short-beak enigma solved
Biologists discovered that a mutation in the ROR2 gene is linked to beak size reduction in numerous breeds of domestic pigeons. Surprisingly, different mutations in ROR2 also underlie a human disorder called Robinow syndrome. The ROR2 signaling pathway plays an important role in the craniofacial development of all vertebrates.  09/21/2021 12:51 PM
