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.....»»
Exploring how cells can be strong at the right place and time
Researchers from TU Delft and NWO institute AMOLF discovered how certain molecular bonds make living cells both flexible, in order to move, as well as strong, in order to withstand forces. Paradoxically, it turns out that these force-sensitive catch.....»»
Bioinspired molecular dyes for biomedical fluorescent imaging
Fluorescence imaging can be conducted with long Stokes shift dyes that minimize crosstalk between the excitation source and fluorescent emission to improve the signal-to-background ratio. Regardless, researchers still form simple, small molecule dyes.....»»
New machine-learning approach facilitates molecular conformer search in complex molecules
CEST researchers developed a new machine learning approach based on a low-energy latent space (LOLS) and density functional theory (DFT) to search for molecular conformers......»»
Amplifying the radiation of molecules after excitation to improve molecular laser spectroscopy
Sensitive animal noses can sniff out trace particles, such as volatile organic compounds, in the ambient air. Humans, on the other hand, are developing innovative technologies for this purpose, such as optical spectroscopy. This uses laser light to d.....»»
Apple store union battle expands to Australia, as in-store anti-union briefings continue
The Apple Store union battle has now expanded to Australia, with a series of Zoom briefings organized by Apple Together. It previously reached the UK. Apple is still attempting to talk retail staff out of joining a union, though it has now made its.....»»

Scientists unravel molecular mechanism of PIN-mediated polar auxin transport
Auxin is the most important hormone in plants. It is mainly synthesized in cotyledons, young leaves and other growing tissues, and is transported to targeted issues via polar transport to regulate plant development and growth. How is this polar auxin.....»»
Design and Build Pull Tray Office Carts
I need to keep my studio organized and looking clean. I prefer to build rolly carts that I can move around and use as needed depending on the projects that I undertake. I have built carts for my 3D printers and those serve me well. I will use MDF ma.....»»
The complex origins of Apiaceae and the current state of research
Recently, scientists from Nanjing Agricultural University summarized the current state of Apiaceae research, including traditional and molecular breeding practices, bioactive compounds, medicinal applications, nanotechnology, and omics research. Curr.....»»
Plant molecular geneticists discover, and begin to crack, the epigenetic code
When plants sense environmental challenges such as drought or extended periods of extreme temperatures, they instinctively reprogram their genetic material to survive and even thrive. The chemical code that triggers those changes can be deciphered an.....»»
Cells regulating blood stem cell maintenance are diverse and conserved between species
Deep molecular analysis of the bone marrow microenvironment reveals that the cells regulating blood stem cell maintenance are more diverse than expected and have features likely to be conserved between species......»»
New study maps the influence of organized crime and the wealthy over Russian foreign policy
Russian foreign policy-making is often guided by elites, intermediaries, private companies, and organized crime groups rather than the national interest, a new study shows......»»
Sugar metabolism is surprisingly conventional in cancer
For over a century, cancer cell metabolism has been viewed as something of a paradox. New work from researchers at Washington University in St. Louis shows that it might not be such an anomaly after all. The study is published Aug. 15 in Molecular Ce.....»»
Newfound Molecular Switch Signals a Thumbs-up or Thumbs-down in the Mouse Brain
This molecule tells the brain whether to put a positive or negative spin on events. Mental disorders may result when the up/down labeling goes awry.....»»
Nanoscale fluid-phase changes revealed
Millions of barrels of oil are produced daily from shale reservoirs, yet a significant amount remains untouched, trapped in molecular-sized pores on a nanoscale. Current reservoir models can't predict oil behavior or recovery at this scale, so compan.....»»
Scientists provide new insights into flowering dates in Prunus species
Recently, scientists from the French National Institute for Agriculture provided new insights into the control of flowering dates in Prunus species, paving the way for development of molecular breeding strategies......»»
Chemists achieve "molecular editing" feat
Chemists from Scripps Research and the University of California, Los Angeles, have developed methods for the precise, flexible modification of a broad class of chemical compounds called bicyclic aza-arenes, which are commonly used to build drug molec.....»»
Scientists hid encryption key for Wizard of Oz text in plastic molecules
It's "a revolutionary scientific advance in molecular data storage and cryptography." Enlarge / Scientists from the University of Texas at Austin encrypted the key to decode text of the The Wizard of Oz in polymers. (credit: S.D. Dahlh.....»»
How do PA, ABA, and CBF pathways synergistically regulate melon cold tolerance?
Polyamines (PAs), including putrescine (Put, a diamine), spermidine (Spd, a triamine), and spermine (Spm, a tetramine), are low-molecular-weight polycations and aliphatic nitrogen-containing substances. They play important roles in the overall life c.....»»
A matter of concentration: Molecular mechanisms of water homeostasis
When making a soup, maintaining the correct balance of liquid and salt is key. Similarly, maintaining the balance of water and electrolytes is an important physiological process in the human body, and disruption of this process can have serious conse.....»»
