Coelacanths may live nearly a century, five times longer than researchers expected
Once thought to be extinct, lobe-finned coelacanths are enormous fish that live deep in the ocean. Now, researchers reporting in the journal Current Biology on June 17 have evidence that, in addition to their impressive size, coelacanths also can live for an impressively long time--perhaps nearly a century.

Predicting resistance to anticancer drugs
Cancer cells can develop resistance to therapy through both genetic and non-genetic mechanisms. But it is unclear how and why one of these routes to resistance prevails. Understanding this 'choice' by the cancer cells may help us devise better therapeutic strategies. Now, the team of Prof. Jean-Christophe Marine (VIB-KU Leuven Center for Cancer Biology) shows that the presence of certain stem cells correlates with the development of nongenetic resistance mechanisms.

State of the art and future directions in the clinical application of HR-pQCT in adults
In recent years, significant progress has been made towards the use of high-resolution peripheral computed tomography (HR-pQCT) imaging in research, and new potential for applications in the clinic have emerged. This new publication by the Joint IOF-ASBMR-ECTS HR-pQCT Working Group provides an important overview of current clinical applications of HR-pQCT in adults, valuable guidance on interpretation of results, and a summary of novel applications and future directions.

RUDN mathematician builds a COVID-19 spread model -- it shows how vaccination affects pandemic
RUDN University mathematicians built a model of COVID-19 spreading based on two regression models. The mathematicians divided the countries into three groups, depending on the spreading rate and on the climatic conditions, and found a suitable mathematical approximation for each of them. Based on the model, the mathematicians predicted the subsequent waves. The forecast was accurate in countries where mass vaccination was not introduced.

Sensitive and specific detecting biomarker of radiation-resistant nasopharyngeal carcinoma
In our study, we constructed a detecting platform based on TpTta-COF nanosheets and fluorescent probe. The TpTta-COF nanosheets can adsorb single-stranded DNA (ss-DNA) probes and quench the fluorescence of ss-DNA. The method enables to capture miR-205 sensitively in aqueous solution with a detection limit of 4.78 nM in the range 0-500 nM and R2 = 0.989, and the method offers great specificity in that it can distinguish the target miRNA from mismatch non-target miRNAs.

Bronze Age Scandinavia's trading networks for copper settled
500 years after the full implementation of copper technology in Scandinavia, the trade that brought the much needed copper to Denmark and southern Sweden also expanded across the Alps. At this time, Bronze Age Scandinavians already traded frequently in central Europe and across the North Sea.

Vortex, the key to information processing capability: Virtual physical reservoir computing
By virtually reproducing physical reservoir computing, a new information processing technology, using numerical simulation, the present study reveals that vortices in fluid flow phenomena in the downstream region of a cylinder are the key to information processing capability. It is expected that this result concerning fluid flow vortices and information processing capability will be useful in enhancing the information processing capability of the physical reservoir using fluid flow.

Passing the COVID test in just five minutes
Osaka University researchers create an intelligent nanopore system sensitive enough to detect single SARS-CoV-2 virus particles. By training a machine-learning algorithm, the platform was able to identify between various coronaviruses in just five minutes. This work may lead to fast and accurate point-of-care testing for COVID and other communicable diseases.

After the big storm: How to supply emergency power
As demand for electricity rises and climate change brings more frequent and extreme storms, residents in rural and suburban communities must have access to the minimal electricity they need to survive a large, long-duration (LLD) power outage.

Mutant genes can promote genetic transfer across taxonomic kingdoms
Researchers from Hiroshima University now have a better understanding of the mechanism underlying how certain bacteria can transfer genetic material across taxonomic kingdoms, including to fungi and protists. Their work, published in Frontiers in Microbiology, could have applications in changing how bacteria perform certain functions or react to changes in their environment.

Prototype may diagnose common pregnancy complications by monitoring placental oxygen
Researchers at the National Institutes of Health have developed a prototype device that could potentially diagnose pregnancy complications by monitoring the oxygen level of the placenta. The device sends near-infrared light through the pregnant person's abdomen to measure oxygen levels in the arterial and venous network in the placenta.

Numerical study first to reveal origin of 'motion of the ocean' in the straits of Florida
Using a numerical model that simulates ocean currents, researchers are shedding light on the important "motion of the ocean" in the Straits of Florida. They have conducted a first-of-its-kind study identifying the mechanisms behind the formation of sub-mesoscale eddies, which have important environmental implications and play a significant role in the health of the Florida Keys coral reef ecosystem.

Study of young chaotic star system reveals planet formation secrets
A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation.

Alpine plant spins its own flavonoid wool
Like the movie version of Spider-Man who shoots spider webs from holes in his wrists, a little alpine plant has been found to eject cobweb-like threads from tiny holes in specialised cells on its leaves. It's these tiny holes that have taken plant scientists by surprise because puncturing the surface of a plant cell would normally cause it to explode like a water balloon.

When tyrannosaurs dominated, medium-sized predators disappeared
A new study in the Canadian Journal of Earth Sciences shows that medium-sized predators all but disappeared late in dinosaur history wherever Tyrannosaurus rex and its close relatives rose to dominance. In those areas -- lands that eventually became central Asia and Western North America -- juvenile tyrannosaurs stepped in to fill the missing ecological niche previously held by other carnivores.

Pandemic adolescent mental health study reveals turnaround finding
Young people with poor mental health took a turn for the better during the pandemic but those with good mental health saw a considerable decline, new research reveals.The first nationally representative evidence regarding the diverse impact of the COVID-19 pandemic on adolescent mental health in the UK was led by researchers at Lancaster University working with the University of British Columbia in Canada.

New invention keeps qubits of light stable at room temperature
Researchers from University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at -270 degrees. Their discovery saves power and money and is a breakthrough in quantum research.
