Receiving at least one dose of a covid-19 vaccine before the first infection is strongly associated with a reduced risk of developing post-covid-19 condition, commonly known as long covid, finds a study published by The BMJ today. The findings, based on data for more than half a million Swedish adults, show that unvaccinated individuals were almost four times as likely to be diagnosed with long covid than those who were vaccinated before first infection. The researchers stress that causality ...

Change in clinical practice would have clear benefits for patients undergoing major bowel surgery, according to analysis conducted by researchers from UCL and the Royal Devon and Exeter Hospital. The study, published in The British Journal of Surgery, provides evidence that giving iron intravenously before colorectal surgery improves outcomes for patients, reducing the need for blood transfusion by 33%. Anaemia is a common problem in patients undergoing bowel surgery due to bleeding from the gut and blood loss during the operation. Anaemia is also associated ...

Blueberry, a common Vaccinium species with small-sized berries, is known for its delicious taste, balanced sweetness and acidity, and rich nutritional content. It is abundant in various vitamins and antioxidants. However, the limited genetic resources for cultivated blueberries have significantly hindered their development and utilization. Therefore, utilizing wild blueberries' genetic resources for breeding is paramount to enhancing the resilience and quality of cultivated varieties. Vaccinium duclouxii, native to the southwestern region of China, is an endemic wild blueberry ...

Chinese and Russian cooperation has grown significantly in the past three decades thanks to joint work on energy trade, politics and official visits, analysis shows. There was a ‘limited’ Sino–Russian cooperation intensity in 1992–1995, which grew from then until 2007 and then rose. The bilateral relationship grew progressively, with no exponential growth or peaks, according to the study. There were no or dramatic changes following Russia’s 2014 annexation of Crimea. The ...

A team of investigators from Massachusetts General Hospital (MGH), Brigham and Women’s Hospital (BWH), and the Broad Institute of MIT and Harvard have developed a non-invasive genetic test that can screen the blood of pregnant individuals to survey all genes for fetal DNA sequence variants. The team evaluated the test by examining blood samples from 51 pregnant persons, finding that the test was able to capture variants that were inherited from the mother as well as new variants that were not present in the mother and associated with prenatal diagnoses. ...

“Our study may reveal previously uncharacterized population-specific variants that may increase the risk of BC in the Kazakh population.” BUFFALO, NY- November 22, 2023 – A new research paper was published in Oncotarget's Volume 14 on October 4, 2023, entitled, “Determination of genetic predisposition to early breast cancer in women of Kazakh ethnicity.” Breast cancer (BC) is the most common type of cancer among women in Kazakhstan. To date, little data are available on the spectrum of genetic variation in Kazakh women with BC. In this new study, researchers Gulnur Zhunussova, Nazgul Omarbayeva, ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, NOVEMBER 22, 2022 MINNEAPOLIS – Black people who eat more foods with whole grains, including some breads and cereals, quinoa, and popcorn, may have a slower rate of memory decline compared to Black people who eat fewer whole grain foods, according to a study published in the November 22, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The researchers did not see a similar trend in white participants. The study does not prove that eating more whole grains slows memory decline; it only shows an association. The study found that among Black ...

A new publication from Opto-Electronic Science; DOI  10.29026/oes.2023.230021 overviews multi-synaptic photonic SNN based on a DFB-SA chip.   Compared with traditional artificial neural networks, spiking neural networks (SNN) are more biologically authentic, more powerful, and less power-consuming due to their spatiotemporal coding and event-driven characteristics. In recent years, optical computing has been widely considered as a hardware acceleration platform, where nonlinear computing poses a challenge. Photonic SNN provides an ultra-fast and energy-efficient platform for high-performance ...

A new publication from Opto-Electronic Science; DOI  10.29026/oes.2023.230019  overviews optical trapping of optical nanoparticles.   This article reviews the fundamentals and applications of optically trapped optical nanoparticles. Optical nanoparticles are nowadays one of the key elements of photonics. They do not only allow optical imaging of a plethora of systems (from cells to microelectronics), but also behave as highly sensitive remote sensors. In recent years, it has been demonstrated the success of optical tweezers in isolating and manipulating individual optical nanoparticles. This has opened the door to high resolution single particle scanning ...

Modern hippos first dispersed in Europe during the Middle Pleistocene, according to a study published November 22, 2023 in the open-access journal PLOS ONE by Beniamino Mecozzi of the Sapienza University of Rome and colleagues. Modern hippos, Hippopotamus amphibius, arose from African ancestors during the Quaternary, a time when hippos were widespread in Europe. However, the details of the modern species’ origin and dispersal into Europe are unclear and highly debated. In this study, Mecozzi and colleagues provide new insights via analysis of a fossil hippo skull from the study area of Tor di Quinto in Rome. The skull of Tor di Quinto, currently housed at the ...

Spurred by the current climate crisis, there has been a heightened attention within the scientific community in recent years to how past climate variation contributed to historic human migration and other behaviors.  Now, an international group of scientists — including archaeologists, historians, climate scientists, paleo-scientists, a volcanologist and others — are calling for a strengthened commitment to transdisciplinary collaboration to study past and present human-environmental interactions, which they say will advance our understanding of these complex, entangled histories. Their recommendations were published ...

WASHINGTON – Using a specialized device that translates images into sound, Georgetown University Medical Center neuroscientists and colleagues showed that people who are blind recognized basic faces using the part of the brain known as the fusiform face area, a region that is crucial for the processing of faces in sighted people. The findings appeared in PLOS ONE on November 22, 2023. “It’s been known for some time that people who are blind can compensate for their loss of vision, ...

Susceptibility to misinformation and disinformation likely to have played part in Leave vote New research from the University of Bath’s School of Management finds that higher cognitive ability was strongly linked to voting to Remain in the 2016 UK referendum on European Union Membership. The study shows that cognitive skills including memory, verbal fluency, fluid reasoning and numerical reasoning, were correlated with how people decided to vote.  Lead author Dr Chris Dawson, from the University of Bath’s School of Management, said: “This study adds to existing academic evidence showing that low ...
