A new Finnish study shows that 180 health care workers who had received two doses of the Pfizer and Biontech vaccine have very good antibody responses against the SARS-CoV-2 virus. The immune response was as strong against the alpha variant (formerly the UK variant) but was somewhat decreased against the beta variant (formerly the South Africa variant). Finnish researchers from the University of Turku and University of Helsinki together with Turku University Hospital, Helsinki University Hospital, and the Finnish Institute for Health and Welfare studied the immune response induced by the coronavirus vaccinations, which started in Finland in December. The researchers analysed vaccine responses ...

Growing in popularity, unagi kabayaki - grilled freshwater eel in soy sauce - can be found on the menu of many Japanese restaurants, and is stocked by Asian shops and in specialist supermarkets. But new research tracing the DNA of eel fillets used for this dish has found that fraudulent food labelling is rife, with a third of the products violating EU regulations on the provision of food information. With certain species of eels now endangered, the researchers say that accurate labelling on these products is vital if the global eel trade is to be sustainable. The European eel is a critically ...

Plants play an essential role in curbing climate change, absorbing about one-third of the carbon dioxide emitted from human activities and storing it in soil so it doesn't become a heat-trapping gas. Extreme weather affects this ecosystem service, but when it comes to understanding carbon uptake, floods are studied far less than droughts - and they may be just as important, according to new research. In a global analysis of vegetation over more than three decades, Stanford University researchers found that photosynthesis - the process by which plants take up carbon dioxide from the atmosphere - was primarily influenced by floods and heavy rainfall nearly as often as droughts in many locations. The paper, published in Environmental Research Letters on June ...

A key component of next-generation solar panels can be created without expensive, high-temperature fabrication methods, demonstrating a pathway to large scale, low-cost manufacturing for commercial applications. Nickel oxide (NiO) is used as an inexpensive hole-transport layer in perovskite solar cells because of its favourable optical properties and long-term stability. Making high-quality NiO films for solar cells usually requires an energy intensive and high-temperature treatment process called thermal annealing, which is not only costly, but also incompatible with plastic substrates, until now precluding the use of ...

Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers from the University of Basel recently came to this conclusion, making the case for better cultivation of spatial reasoning. Good math skills open career doors in the natural sciences as well as technical and engineering fields. However, a nationwide study on basic skills conducted in Switzerland in 2019 found that schoolchildren achieved only modest results in mathematics. But it seems possible to begin promoting math skills from a young ...

New research shows thermal imaging techniques can predict whether a wound needs extra management, offering an early alert system to improve chronic wound care. It is estimated that 1-2% of the population will experience a chronic wound during their lifetime in developed countries - in the US, chronic wounds affect about 6.5 million patients with more than US$25 billion each year spent by the healthcare system on treating related complications.* The Australian study shows textural analysis of thermal images of venous leg ulcers (VLUs) can detect whether a wound needs extra management as early as week two for clients receiving treatment at home. The clinical study by RMIT University and Bolton Clarke, published in the Nature journal Scientific Reports, is the first to investigate ...

Decision-makers around the world are increasingly interested in using ecosystem solutions such as mangroves, coral reefs, sand dunes and forests on steep slopes to help buffer the impacts from hazard events and protect populations. But what evidence exists to show the efficacy of nature-based solutions over man-made protective measures to reduce the impacts of the increasing numbers of hazard events humanity faces due to climate change? An international, multi-disciplinary team of 28 researchers has examined nearly 20 years' worth of peer-reviewed studies on the impacts of ecosystem-based disaster ...

A study analysing the association between a wide variety of prenatal and childhood exposures and neuropsychological development in school-age children has found that organic food intake is associated with better scores on tests of fluid intelligence (ability to solve novel reasoning problems) and working memory (ability of the brain to retain new information while it is needed in the short term). The study, published in Environmental Pollution, was conceived and designed by researchers at the Barcelona Institute for Global Health (ISGlobal)--a centre supported by the "la Caixa" Foundation--and ...

A scientific breakthrough: Researchers from Tel Aviv University have engineered the world's tiniest technology, with a thickness of only two atoms. According to the researchers, the new technology proposes a way for storing electric information in the thinnest unit known to science, in one of the most stable and inert materials in nature. The allowed quantum-mechanical electron tunneling through the atomically thin film may boost the information reading process much beyond current technologies. The research was performed by scientists from the Raymond and Beverly Sackler School of Physics and Astronomy and Raymond and Beverly Sackler School of Chemistry. The group includes Maayan Vizner Stern, Yuval Waschitz, Dr. Wei Cao, Dr. Iftach Nevo, Prof. Eran Sela, Prof. Michael Urbakh, ...

Working out just five minutes daily via a practice described as "strength training for your breathing muscles" lowers blood pressure and improves some measures of vascular health as well as, or even more than, aerobic exercise or medication, new CU Boulder research shows. The study, published June 29 in the Journal of the American Heart Association, provides the strongest evidence yet that the ultra-time-efficient maneuver known as High-Resistance Inspiratory Muscle Strength Training (IMST) could play a key role in helping aging adults fend off cardiovascular disease - the nation's leading killer. In the United States alone, 65% of adults over age 50 have ...

A University of Arkansas researcher and international colleagues found that employed individuals, on average, are 35.3% more likely to be infected with the flu virus. The findings confirm a long-held assumption about one prevalent way illness spreads and could influence government policy on public health and several issues for private companies, from optimal design and management of physical work spaces to policy decisions about sick leave and remote work. To track influenza incidence, Dongya "Don" Koh, assistant professor of economics in the Sam M. Walton College of Business, and colleagues relied on nationally representative data from the Medical ...

A new study shows that colleges students are experiencing significant grief reactions in response to the COVID-19 pandemic. The paper, "College Student Experiences of Grief and Loss Amid the COVID-19 Global Pandemic," was recently published in OMEGA - Journal of Death and Dying. "This study aimed to identify the most common non-death losses and grief reactions experienced by undergraduate and graduate college students amid the pandemic," said author Erica H. Sirrine, Ph.D., director of Social Work at St. Jude Children's Research Hospital. "What we found is that students ...

New Brunswick, N.J. (June 28, 2021) - Rutgers researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power. The findings appear in the journal Applied Energy. Offshore wind is rapidly maturing into a major source of renewable energy worldwide and is projected to grow by 13% in the next two decades and 15-fold by 2040 to become a $1 trillion industry, matching capital spending on gas- and coal-fired power generation. In the United States, for instance, New York and New Jersey recently awarded two offshore ...

When it comes to climate change, not all organisms will lose out. A new Cal Poly study finds that rattlesnakes are likely to benefit from a warming climate. A combination of factors makes a warming climate beneficial to rattlesnakes that are found in almost every part of the continental United States but are especially common in the Southwest. Rattlers are experts at thermoregulation. Researchers found that, when given a choice, the snakes prefer a body temperature of 86-89 degrees Fahrenheit, a much warmer temperature than they generally experience in nature. The average ...

CHICAGO (June 30, 2021) -- Four leading medical specialty societies released a new clinical practice guideline today that includes recommendations for reducing blood loss during heart surgery and improving patient outcomes. The document, a multidisciplinary collaboration among The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, the American Society of ExtraCorporeal Technology, and the Society for the Advancement of Patient Blood Management, is available online in The Annals of Thoracic Surgery and two other journals. "As medicine evolves and we learn more, it always is important to review past ...

Na3V2(PO4)2F3(NVPF), a cathode material used in sodium-ion batteries (SIB), features ultrafast Na+ migration and high structural stability because of its three-dimensional open framework. However, the poor intrinsic electronic conductivity of NVPF often leads to high polarization, low Coulombic efficiency, and unsatisfactory rate performance, which hinder its commercial application. Recently, a group led by Prof. Shuangqiang Chen and Prof. Yong Wang from Shanghai University synthesized zirconium-doped NVPF nanoparticles coated with a nitrogen-doped ...

Researchers at Chalmers University of Technology, Sweden, have succeeded in developing a method to label mRNA molecules, and thereby follow, in real time, their path through cells, using a microscope - without affecting their properties or subsequent activity. The breakthrough could be of great importance in facilitating the development of new RNA-based medicines. RNA-based therapeutics offer a range of new opportunities to prevent, treat and potentially cure diseases. But currently, the delivery of RNA therapeutics into the cell is inefficient. For new therapeutics to fulfil ...

Wine grapes are particularly finicky when it comes to their environment. For instance, heatwaves and droughts lead to earlier berry ripening and lackluster wine. And these types of episodes are expected to intensify as Earth's climate changes. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have tweaked growing conditions for Cabernet Sauvignon grapes to slow down their ripening, which increased the levels of compounds associated with wine's characteristic floral and fruity notes. As grapes ripen and change color from light green to deep red, sugars and aroma compounds accumulate in the berries. But, when they ripen quickly because of heat or water stress, the resulting fruits produce ...

Amyotrophic lateral sclerosis, or ALS, attacks nerve cells known as motor neurons in the brain and spinal cord, gradually leading to paralysis. The loss of function of an important gene, C9orf72, may affect communication between motor neurons and muscles in people with this disease. These findings were revealed by the team of Dr Kessen Patten of the Institut national de la recherche scientifique (INRS) in the prestigious journal Communications Biology. A mutation in the C9orf72 gene is the primary genetic cause of ALS. The mutation in C9orf72 consists of an expansion of a sequence of six DNA bases (GGGGCC) that is very unusual, going from a few copies (less than 20 in a healthy person) to more than 1000 copies. The mutation, in part resulting in a loss of function, ...

DALLAS, June 30, 2021 -- Regularly eating a Southern-style diet may increase the risk of sudden cardiac death, while routinely consuming a Mediterranean diet may reduce that risk, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association. The Southern diet is characterized by added fats, fried foods, eggs, organ meats (such as liver or giblets), processed meats (such as deli meat, bacon and hotdogs) and sugar-sweetened beverages. The Mediterranean diet is high in fruits, vegetables, fish, whole grains and legumes and low in meat and dairy. "While this study was observational in nature, the results suggest that diet may be a modifiable risk factor for sudden cardiac death, and, therefore, diet ...

Arlington, Va., June 30, 2021 - Much has been rightfully made of the valiant work of doctors and nurses during the coronavirus pandemic. But what of infection preventionists (IP), whose job was to keep those workers and their facilities safe, and who many Americans do not even know exist? At the Association for Professionals in Infection Control and Epidemiology's (APIC's), 48th Annual Conference, the head of infection prevention at a top New York City hospital presented an iterative diary, kept in real time by infection preventionists during the height of the pandemic, from March-July 2020. Almost 50 IPs completed more than 150 surveys over 14 survey rounds during those four dark months and told of the fear that frontline medical workers felt. "Fear ...

How common COVID-19 is among infants may depend on the degree of the pandemic virus circulating in a community, a new study finds. Published online June 30 in the journal Pediatrics, the study found specifically that rates of the infection with the virus that causes COVID-19 were higher among infants hospitalized, not for COVID-19 - but instead because they were being evaluated for a potential serious bacterial infection (SBI) - during periods of high COVID-19 circulation in New York City. The study also found rates of COVID-19 positivity in this age group were lower when infection rates in the city were low. Led by researchers from NYU Langone Health, the study also examined the clinical course of the infection in young infants and found that the most ...

CLEVELAND, Ohio (June 30, 2021)--The link between obesity and the risk of endometrial cancer has been well documented. A new study, however, shows that an even lower body mass index (BMI) than previously thought can signal an increased risk in Asian women with postmenopausal bleeding. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS). Endometrial cancer is the sixth most common form of cancer in women worldwide and is a leading cause of cancer death. Because there is currently no routine screening for endometrial cancer in asymptomatic women, it is important for healthcare professionals to be aware of added risk factors so that ...

Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. For the past decade, astrophysicists have been gradually dividing into two camps: one that believes that the difference is significant, and another that thinks it could be due to errors in measurement. If it turns out that errors are causing the mismatch, that would confirm our basic model of how the universe works. The other possibility presents a thread that, when pulled, would suggest some fundamental missing new physics is needed to stitch it back together. For several years, each new piece ...

Oncotarget published "High in vitro and in vivo synergistic activity between mTORC1 and PLK1 inhibition in adenocarcinoma NSCLC" which reported that the aim of this study was therefore to define combination of treatment based on the determination of predictive markers of resistance to the mTORC1 inhibitor RAD001/Everolimus. When looking at biomarkers of resistance by RT-PCR study, three genes were found to be highly expressed in resistant tumors, i.e., PLK1, CXCR4, and AXL. The authors have then focused this study on the combination of RAD001 Volasertib, a PLK1 inhibitor, and observed a high antitumor activity ...
