Molecular gardening: New enzymes discovered for protein modification pruning
Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders......»»
Researchers identify two fungal enzymes that hijack the immune system of plants to colonize roots
In nature, plant roots are always colonized by fungi. This interaction can be either mutualistic, benefiting both the plant and the fungus, or pathogenic, where the fungus harms the host plant. A research group led by Professor Dr. Alga Zuccaro at th.....»»
Cell model identifies important factor in neural development
The Wistar Institute's Alessandro Gardini, Ph.D., and lab have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular "bridge" complex demonstrate a new level of detail in the under.....»»
Dogs prefer texture over shape when identifying objects, research reveals
In a new study exploring how dogs recognize and generalize objects, researchers from Eötvös Lorand University (Budapest) discovered that dogs prioritize texture over shape when identifying objects. The paper is published in the journal Scientific R.....»»
Decoding the structure of nano "gene ferries" to advance RNA drugs
LMU researchers have investigated how cationic polymers organize on a molecular level when transporting RNA drugs......»»
ESET researchers analyze first UEFI bootkit for Linux systems
ESET Research has discovered the first UEFI bootkit designed for Linux systems, named Bootkitty by its creators. Researchers believe this bootkit is likely an initial proof of concept, and based on ESET telemetry, it has not been deployed in the wild.....»»
From days to hours: A faster way to make a promising new catalyst
Scientists have discovered a faster, more sustainable method for making metal-encapsulated covalent organic frameworks (COFs), materials that have the potential to play a crucial role in catalysis, energy storage, and chemical sensing......»»
Researchers reveal exploitable flaws in corporate VPN clients
Researchers have discovered vulnerabilities in the update process of Palo Alto Networks (CVE-2024-5921) and SonicWall (CVE-2024-29014) corporate VPN clients that could be exploited to remotely execute code on users’ devices. CVE-2024-5921 CVE-2.....»»
Magnetically driven vortices may be generating Earth-size concentrations of hydrocarbon haze at Jupiter"s poles
While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet's north and south poles that appear and disappear seemingly at r.....»»
Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published November 19 in The Astr.....»»
A molecular trap for exotic metals promises improved diagnostics and faster drug development
A group of scientists from IOCB Prague, led by Dr. Miloslav Polášek, have created compounds that are up to a million times more stable than similar substances used in contemporary medicine to treat tumors or as contrast agents for magnetic resonanc.....»»
Molecular morphers: DNA-powered gels shape-shift on command
Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter or number to another when tri.....»»
On the trail of an 18th-century master forger: New evidence discovered
A document held in Göttingen University's Faculty of Humanities has been revealed as an 18th century forgery. The document purports to be from 1266, but mentions a church in Pisa that was not built until later. This discovery is the result of resear.....»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Next-generation, nature-inspired sunscreens have a new molecular scaffold
A team of researchers led by professors Wybren Jan Buma at the University of Amsterdam and Vasilios Stavros at the University of Warwick (U.K.) have laid the groundwork for using urocanic acid and its derivatives as a novel class of sunscreen filters.....»»
Fossil discovery reveals giant worm lizard with snail-cracking jaws
An international team of researchers has discovered a new fossil worm lizard species in Tunisia. Terastiodontosaurus marcelosanchezi is the largest known species of the Amphisbaenia group, with a skull length of over five centimeters......»»
tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein can be made. They publis.....»»
Study reveals RNA"s unknown role in DNA damage repair
A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative disorders while chan.....»»
Are fast radio bursts caused by interstellar objects crashing into neutron stars?
Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were first discovered a couple of decades ago, we had.....»»
New structure gives insight into mRNA export and cancers, and how viruses hijack the process to infect their host
The central dogma of biology defines the flow of genetic information: It describes how proteins are made from mRNA templates, which are in turn made from DNA. Exporting the mRNA from inside the nucleus to the site of protein translation in the cytopl.....»»
Spatial interactomics tool maps protein interactions to fight lung cancer
As Ahmet F. Coskun and his team of researchers continue their mission to create a 3D atlas of the human body, mapping cells and tissues, they're making discoveries that could lead to better treatments for the most common type of lung cancer......»»
