Optimality in self-organized molecular sorting
The eukaryotic cell is the basic unit of animals and plants. Through the microscope, it looks highly structured and subdivided in many membrane-bound compartments. Each compartment has a specific function, and its membrane is populated by specific mo.....»»
Protecting biocatalysts from oxygen
Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their use is that they are des.....»»
Study shows circadian clock helps cells recover during starvation
Cells with a functioning molecular clock are better able to adapt to changes in glucose supply and can recover faster from long-term starvation, according to a study published today in eLife......»»
Insights into the formation of ATP synthase: A new important function of the folding helper Hsp70
Scientists led by Prof. Thomas Becker, Director of the Institute of Biochemistry and Molecular Biology at the University Hospital Bonn (UKB), have gained new insights into the formation of ATP synthase, the turbine of the cells' power plants, the mit.....»»
Weiss-Kruszka syndrome and the failure to establish neuronal identity
Weiss-Kruszka syndrome is a rare neurodevelopmental disorder characterized by craniofacial anomalies, developmental delay, and autistic features. Researchers at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences and t.....»»
New metric of molecular evolution in the search for the genetic basis of phenotypic traits
With its powerful digging shovels, the European mole can burrow through the soil with ease. The same applies to the Australian marsupial mole. Although the two animal species live far apart, they have developed similar organs in the course of evoluti.....»»
Study creates new open-access database to better identify plastic pollution sources
Research led by the Monterey Bay Aquarium and MBARI (Monterey Bay Aquarium Research Institute) provides a new open-access Raman spectral library that can be used to detect molecular "fingerprints" of particles and better trace sources of ocean plasti.....»»
Enabling nanoscale thermoelectrics with a novel organometallic molecular junction
The Seebeck effect is a thermoelectric phenomenon by which a voltage or current is generated when a temperature difference exists across a conductor. This effect is the basis of established and emerging thermoelectric applications alike, such as heat.....»»
Harnessing tumor"s power to heal non-healing wounds
Scientists have discovered a way to train healthy immune cells to acquire the skills of some tumor cells—but for a good purpose—to accelerate diabetic wound healing. This remarkably promising finding, recently published in EMBO Molecular Medicine.....»»
Breakthrough in plant breeding: Grafting and mobile CRISPR for genome editing in plants
A ground-breaking twist to the CRISPR tool—aka "genetic scissors"—is being put to use to edit plant genomes by scientists from the Max Planck Institute of Molecular Plant Physiology, signaling a methodology change. The discovery, recently publish.....»»
Tracking the adversary
Raj Samani, SVP, Chief Scientist, Rapid7, discusses the tactics observed from a recent case of espionage, and what can be learned from such observations. This video was recorded at IRISSCON 2022, an annual conference organized by IRISSCERT. The all-d.....»»
Tech resolutions to kick off 2023: Rotate backups, export photos out of iCloud, experiment with self-hosting tools, and more
As we kick off 2023, it’s a good time to start thinking about tech resolutions for the coming year. These resolutions can help us stay organized, secure, and up-to-date with the latest technology. Here are some tech resolutions for 2023 that I am.....»»
Scientists uncover a novel cellular mechanism that regulates aging and fertility
Research at the Institute of Molecular Biology and Biotechnology (IMBB) of the Foundation for Research and Technology-Hellas (FORTH), published today in the journal Nature Aging, reveals a fundamental quality control mechanism that operates in cells.....»»
Researchers discover "Humpty-Dumpty" water-based mechanism of human sex reversal at edge of developmental ambiguity
Researchers from Indiana University School of Medicine have discovered a molecular "clamping" mechanism within a male-specific protein-DNA complex whose mutation causes sex reversal: children with XY chromosomes but female bodies, a condition called.....»»
Collective circular dichroism by chiral plasmonic nanoparticles
Molecular chirality refers to the geometrical property of molecules with broken mirror symmetry. Characterizing molecular chirality and understanding their roles in physiochemical situations has been important in broad research scope such as, biology.....»»
What TSMC CEO CC Wei says about the semiconductor industry (1)
On a cold and wet weekend morning last week, TSMC CEO CC Wei delivered a speech at an event organized by the Monte Jade Science and Technology Association on the topic of "New Challenges in the Semiconductor Industry.".....»»
3D structure of mammalian genome reveals record-breaking diversity
The genome (the code of life) is organized in the form of folded chromosomes within the nucleus of cells. This three-dimensional organization of the genome is fundamental, as it determines which genes are switched on and off in each cell type. Compar.....»»
AI image recognition allows automatic identification and sorting of single bacterial cells
The identification, sorting and export of single bacterial cells rather than populations of them has long been incredibly complex, expensive and often just does not work without damaging the cells......»»
The clever glue keeping the cell"s moving parts connected
Researchers from Paul Scherrer Institute PSI and ETH Zurich have discovered how proteins in the cell can form tiny liquid droplets that act as a smart molecular glue. Clinging to the ends of filaments called microtubules, the glue they discovered ens.....»»
A poison helps us understand molecular hydrogen-producing biocatalysts
In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore of interest for biobased hydrogen production. Although.....»»
Some cancer cells may not be as immortal as previously thought
Scientists at Johannes Gutenberg University Mainz (JGU) and the Institute of Molecular Biology (IMB) in Mainz may have discovered new insights into how cancer cells regulate the ends of their chromosomes, called telomeres. Certain cancers use a speci.....»»
