Unfolding the blindness proteins through fly eyes
Every 6 minutes someone is told they're going blind. One of the major causes of human blindness is a disease called Retinitis Pigmentosa (RP), which causes progressive degeneration of the retina and vision loss. Approximately one-tenth of Retinitis.....»»
Biologists" mapping method illustrates paths to new proteins
Scientists at The University of Texas at Dallas are using machine learning to study proteins—the molecules that carry out essential life functions—in a way that could impact protein engineering, human health and the evolutionary tracking of prote.....»»
How one of nature"s most fundamental molecules forms
Life runs on ribosomes. Every cell on Earth needs ribosomes to translate genetic information into all the proteins needed for the organism to function—and to in turn make more ribosomes. But scientists still lack a clear understanding of how these.....»»
Honor’s new Android phone has a feature we’ve never seen before
The new Honor 90 has a big 6.7-inch screen, but what makes it special is the industry-first anti-flicker technology to save your eyes......»»
Chemists discover why photosynthetic light-harvesting is so efficient
When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, cells convert the energy into electrons, which eventu.....»»
Scientists pinpoint where thousands of individual proteins are made in intact tissue and single cells
For researchers studying how proteins can cause human disease, knowing precisely where proteins are made within cells and tissues could help them learn about their role in disease and come up with new treatments......»»
Prepared for war: How cells survive viral invasion
"Let him who desires peace, prepare for war," wrote the Roman author Vegetius in the 4th century CE. Our bodies, it seems, live by this dictum: Even in times of peace, some cells express high levels of defensive, antiviral proteins. A new Weizmann In.....»»
Clever fly offers lessons on advanced predator adaptations
The saffron robber fly (Laphria saffrana) is an extremely fast bee-colored hunter that has to determine, while perched, which insects it wants to chase and eat. This is complicated by the fact that its eyes have poor resolution, especially at distanc.....»»
Molecular "hub" regulates gene-silencing proteins
To keep their vital functions in balance, many organisms use small snippets of RNA to "silence" messenger RNAs that code for certain proteins. New research from FMI scientists has revealed a molecular hub that integrates the activities of different p.....»»
Pathogen protein modularity enables elaborate mimicry of host phosphatase
Pathogens have developed an extensive array of proteins during the co-evolutionary arms race with their hosts. This is particularly true for Phytophthora, a genus that causes significant damage to agriculture and forestry. One well-known species, Phy.....»»
Research team shows that a cell"s membrane can be reversibly deformed with light
Membranes fulfill a variety of tasks in living cells: for example, they separate the cells from their surroundings and thus protect them. Also, by means of transport proteins they convey the necessary nutrients to the interior. Membranes are also ins.....»»
Animation shows what the world would look like if you could see carbon dioxide emissions
It's a strange, eerie-looking place. Carbon dioxide gas appears… and disappears in cycles and bursts throughout the year. It's how our planet would look if we could detect carbon dioxide (CO2) with our eyes. Scientists at NASA's Global Modeling and.....»»
This phone may have already beat the Galaxy Z Flip 5 in a big way
All eyes are on the Galaxy Z Flip 5, which is set to be one of the year's best folding phones, but a new competitor may have beaten it even before it launches......»»
Smart yet simple: Creating uniform DNA-encapsulating microgels that mimic a living cell
The living cell harbors physiologically relevant components such as the genetic material (DNA) and proteins in a "self-organized" setting. Understanding this process of self-assembly can reveal the underlying mechanism of self-organization of living.....»»
Bridging the gap for precision medicine: Nanofluidic aptamer nanoarray measures individual proteins
In the evolving world of precision medicine, the need for methods that can measure biomolecules with supreme accuracy and specificity is paramount. Recognizing this, Associate Professor Yan Xu of the Graduate School of Engineering at Osaka Metropolit.....»»
Biolab replaces horseradish roots for production of important enzymes
It is one of the most important enzymes in medical diagnostics: Horseradish peroxidase is used for many medical products—it is often used when a color change of a test strip is to detect the presence of antibodies or other proteins......»»
Ribosomal gatekeepers: Study sheds light on molecular control centers of eukaryote protein factories
Based on genetic blueprints, individual amino acids are assembled into long amino acid chains, the proteins, in the protein factories of our cells, the ribosomes. Each newly formed protein starts with the amino acid methionine. This amino acid is oft.....»»
Nanoparticle drug delivery system super-enhances neuron regeneration in zebrafish eye, new study shows
In a recent study from the Wilmer Eye Institute, researchers say they found that using a nanoparticle to target immune cells in the eyes of zebrafish enhanced neuron regeneration rates after injury. This research expands on previous studies, from Wil.....»»
How proteins protect mammalian sperm on their way to the egg cell
Mammalian seminal fluid contains a variety of proteins secreted by the accessory sex glands that are important for the processes involved in fertilization. One of these proteins, which is found in ungulates—and in particularly large quantities in b.....»»
A roadmap for gene regulation in plants
For the first time, researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression.....»»
Mazda eyes EV battery supply partnership with Panasonic
Panasonic Energy would supply Mazda with automotive cylindrical lithium-ion batteries made in Japan and North America for Mazda EVs expected to be rolled out in the latter half of this decade, the companies said in a statement......»»
