Mimicking a molecule found in poppies
A Rice University undergraduate student's grit and talent paid off in a big way when she introduced the first synthesis of a rare and potentially potent molecule drawn from poppies. .....»»
Fat-secreted molecule lowers response to common cancer treatment
Leptin, a molecule produced by fat cells, appears to cancel out the effects of the estrogen-blocking therapy tamoxifen, a drug commonly used to treat and prevent breast cancers, suggests a new study......»»
Immune system early responder can combat COVID-19
A simple RNA molecule jumpstarts the immune system's 'first responders' to viral infection and can even eradicate the SARS-CoV-2 virus in mice with chronic cases of COVID-19, a new study finds......»»
ESR-STM on single molecules and molecule-based structures
Scaling down information devices to the atomic scale has brought the interest of using individual spins as a basic unit for data storage. This requires precise detection and control of spin states and a better understanding of spin-spin interactions......»»
Scammers steal more than $500,000 using Google Ads for fake crypto wallets
Check Point says the scammers place Google Ads designed to look like official wallet websites like Phantom App or MetaMask. Researchers even saw scams mimicking crypto exchanges such as Pancake Swap. Since these are advertisements, they appear above.....»»
Single molecule controls unusual ants" switch from worker to queen-like status
Depending on the outcome of social conflicts, ants of the species Harpegnathos saltator do something unusual: they can switch from a worker to a queen-like status known as gamergate. Now, researchers reporting in the journal Cell on November 4th have.....»»
Better models of atmospheric "detergent" can help predict climate change
Earth's atmosphere has a unique ability to cleanse itself by way of invisible molecules in the air that act as minuscule cleanup crews. The most important molecule in that crew is the hydroxyl radical (OH), nicknamed the "detergent of the atmosphere".....»»
Drug-like molecule points to novel strategies for cancer therapy
A decade ago, genome sequencing revealed a big surprise: about 50 percent of human cancers are linked to mutations in what are known as epigenetic regulators, which control the activity of genes. Medical researchers have now developed a new drug-like.....»»
How legumes give oxygen to symbiotic bacteria in their roots
Scientists discover the genetics inside legumes that control the production of an oxygen-carrying molecule, crucial to the plant's close relationships with nitrogen-fixing bacteria......»»
Mechanism behind ineffective psoriasis drugs identified
Interleukin-12 -- a messenger molecule of immune cells -- was long considered to trigger the development of psoriasis. Now, researchers have shown that interleukin-12 does not actually cause the skin disease but protects against it. This also explain.....»»
Supernova: A glowing DNA enzyme
Once thought to function primarily as a storage molecule for genetic information, it is now known that DNA can also catalyze chemical reactions. Although such DNA enzymes (deoxyribozymes) have not been identified in nature, they can be isolated in th.....»»
A beacon molecule that prevents vision, behavioral problems in mice
Nestled deep in the middle of the vertebrate brain is a multi-sensory integration and movement control center called the superior colliculus. In rodents, this brain region integrates multi-sensory inputs—visual cues, sounds, touch information, and.....»»
Researchers unlock secret path to a quantum future
In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins of two nuclei in a molecule, with each spin's "up" or "dow.....»»
The complex dynamics of stem cell tethers and slings
An innovative experiment design shows, in real time and at the scale of a single molecule, how stem cells slow their rolling inside the circulatory system by growing long tethers that attach to the inner surfaces of blood vessels. The strategy could.....»»
An unusual molecule protects nerve cells from degeneration
An international research team led by Professor Stephanie Grond from the Institute of Organic Chemistry at the University of Tübingen has found that the natural substance collinolactone reduces artificially-induced stress on nerve cells, protecting.....»»
Intelligence emerging from random polymer networks
Reservoir computing (RC) tackles complex problems by mimicking the way information is processed in animal brains. It relies on a randomly connected network that serves as a reservoir for information and ultimately leads to more efficient outputs. For.....»»
Dreams Update 2.32 Adds New Subtitle Options And Bug Fixes
The Dreams update 2.32 patch notes have been confirmed by Media Molecule. Read up on the latest Dreams patch notes here. The post Dreams Update 2.32 Adds New Subtitle Options And Bug Fixes appeared first on PlayStation Universe. Media Molecule h.....»»
Sequencing multiple RNA base modifications simultaneously: A new era of RNA biology
After a gene is transcribed into RNA, modifications can occur to the subunits or "bases" that make up the RNA molecule, which can affect its structure and function. The study of these changes is known as "epitranscriptomics." These base modifications.....»»
Organic molecule remnants found in nuclei of ancient dinosaur cells
A team of scientists from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and from the Shandong Tianyu Museum of Nature (STM) has isolated exquisitely preserved cartilage cells in a 125-million.....»»
Mimicking how water and wind create complex shapes in nature
Intricate natural formations like star-shaped sand dunes or arc-shaped rocks can appear so purposeful in form that it's easy to wonder whether someone has designed them. Scientists have long recognized that a particular combination of random and chao.....»»
Scientists ID sterol essential for oil accumulation in plants
Scientists seeking to unravel the details of how plants produce and accumulate oil have identified a new essential component of the assembly line. They discovered a particular sterol—a molecule related to cholesterol—that plays a key role in the.....»»
