New antibiotic class effective against multidrug-resistant bacteria discovered
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article i.....»»
Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission......»»
Scientists develop AI tool for personalized phage therapy as a targeted alternative to antibiotics
With the rapid development of antibiotics in the 1930s, phage therapy—using viruses known as bacteriophages or phages to tackle bacterial infections—fell into oblivion. But as the current rise in antibiotic resistance is making it increasingly di.....»»
M4 Mac minis in a computing cluster is incredibly cool, but not hugely effective
There is a way to use a collection of M4 Mac minis in a cluster, but the benefits only really exist when you use high-end Macs.A cluster of M4 Mac minis - Image credit: Alex Ziskind/YouTubeWhile most people think of having a more powerful computer me.....»»
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.....»»
Researchers create high-resistant starch rice by impaired amylopectin synthesis
Rice is one of the most important staple crops and an excellent starch-provider. Resistant starch (RS) has shown beneficial effects on diabetes, weight management and inflammatory bowel disease......»»
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.....»»
Educating young people about social media could be far more effective than a ban—Finland can show us how
The federal government's proposed social media ban for under-16s has sparked widespread debate, affecting millions of young Australians, their families and educators. But will it actually work?.....»»
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.....»»
Introducing "UFO" galaxies—the Milky Way"s dustier cousins
In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red Flattened Objects, or UFOs.....»»
Infrastructure and communication challenges can be barriers to food safety in the low-moisture food industry
Low-moisture foods such as dried fruits, seeds, tree nuts and wheat flour were once considered to carry minimal microbial risks. However, the increased number of outbreaks linked to bacteria-contaminated low-moisture foods has resulted in product rec.....»»
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.....»»
Race-blind college admissions harm diversity without improving quality, study finds
Critics of affirmative action in higher education have argued that the policy deprives more qualified students of a spot at a university or college. A new study by Cornell researchers finds that ignoring race leads to an admitted class that is much l.....»»
Novel nano-vaccine administered as nasal spray found to be effective against all major COVID-19 variants
Researchers at Tel Aviv University have developed an effective, inexpensive, and simple COVID-19 vaccine that can be stored at room temperature and administered as a nasal spray.....»»
DNA-based methods found highly effective for identifying insect species
A team of researchers from Linnaeus University and Linköping University, extensively evaluated DNA barcoding and metabarcoding methods. A comprehensive study has demonstrated that DNA-based methods are remarkably reliable for identifying insect spec.....»»
Support for carbon pricing higher than expected, finds study
Viewed by many experts as one of the most effective tools of climate policy, carbon pricing seeks to reduce carbon dioxide emissions. Currently, however, only 23% of global greenhouse gas emissions are subject to this climate tax, as it is seen as un.....»»
Nature-based solutions are cheap and effective, and governments have the tools to make them a reality
As the world gathers in Azerbaijan for this year's annual UN climate conference (COP29), the urgency to act on climate change has never been greater......»»
