Commonly accepted advice to keep a straight back and squat while lifting in order to avoid back pain has been challenged by new Curtin University research.

The research examined people who had regularly performed manual lifting through their occupation for more than five years and found those who experienced low back pain as a result were more likely to use the recommended technique of squatting and keeping a straight back, while those without back pain tended not to adhere to the recommended lifting advice.

Over the past six months, the World Health Organization has categorized four SARS-CoV-2 variants as being "of concern" because they are more transmissible or may escape the immune response. They have been termed the Alpha, Beta, Gamma and Delta variants. Scientists from the Institut Pasteur, in collaboration with the French National Health Insurance Fund (CNAM), Ipsos and Santé publique France, conducted a nationwide case-control study to evaluate the effectiveness of mRNA vaccines against symptomatic forms of SARS-CoV-2 infection, be that non-variant virus or the Alpha and Beta variants.

Tsukuba, Japan - Rice is the world's most commonly grown and consumed crop. It also supports lives and livelihoods, especially in low- and middle-income regions. As such, methods for securing abundant and profitable rice harvests are key in global food security.

A new study of almost 12,000 Australians has found one-third of the adult population has experienced pure cybercrime during their lifetime, with 14% reporting this disruption to network systems in the past 12 months.

With all forms of cybercrime already costing trillions every year globally, experts from the Australian Institute of Criminology (AIC) and Flinders University say the crimes involved substantial levels of personal victimisation including direct losses as well as the high cost of preventing future attacks.

Researchers from the Antimicrobial Resistance (AMR) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, alongside collaborators from Biobot Analytics, Nanyang Technological University (NTU) and Massachusetts Institute of Technology (MIT), have successfully developed an innovative, open-source molecular detection method that is able to detect and quantify the B.1.1.7 (Alpha) variant of SARS-CoV-2.

Vanderbilt astrophysicist Karan Jani has led a series of studies that make the first case for a gravitational wave infrastructure on the surface of the moon. The experiment, dubbed Gravitational-Wave Lunar Observatory for Cosmology, uses the moon's environment and geocentric orbit to analyze mergers of black holes, neuron stars and dark matter candidates within almost 70 percent of the entire observable volume of the universe, he said.

SARS-CoV-2 still poses major challenges to mankind. The frequent emergence of mutant forms makes the threat posed by the virus difficult to predict. The SARS-CoV-2 variant B.1.617 circulated in India and gave rise to the Delta variant, B.1.617.2, which is now becoming dominant in many countries. Infection researchers from the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen have investigated the B.1.617 variant in detail.

A high proportion of staff working in intensive care units during the COVID-19 pandemic have experienced mental health conditions, according to a new study.

In a study of 515 healthcare staff working in intensive care units (ICUs) across seven countries, the researchers found that on average 48 percent of participants showed signs of mental health conditions - depression, insomnia and post-traumatic stress disorder (PTSD). Their mental health was assessed using a detailed questionnaire and a clinical scoring system.

A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behaviour of active regions and the nature of the solar interior.

A protein involved in making cells move offers a clue to how certain types of cancer metastasize and develop into secondary tumours, according to new research from the University of Warwick.

Scientists from Warwick Medical School have demonstrated for the first time that levels of this protein can increase and decrease the movement of a cell, including cancer cells - suggesting that they could play a role in the spread of tumours.

According to the latest cosmological models, large spiral galaxies such as the Milky Way grew by absorbing smaller galaxies, by a sort of galactic cannibalism. Evidence for this is given by very large structures, the tidal stellar streams, which are observed around them, which are the remains of these satellite galaxies. But the full histories of the majority of these cases are hard to study, because these flows of stars are very faint, and only the remains of the most recent mergers have been detected.

Pregnancy-induced diabetes, also known as gestational diabetes, is a common metabolic complication of pregnancy. The disorder carries a significant risk of adverse obstetric outcome. Additionally, it is associated with a high risk of recurrence, progression to maternal type 2 diabetes as well as an elevated risk of obesity in foetuses exposed to hyperglycaemia during gestation.

In the context of meditation practice, meditators can experience a state of "pure awareness" or "pure consciousness", in which they perceive consciousness itself. This state can be experienced in various ways, but evidently incorporates specific sensations as well as non-specific accompanying perceptions, feelings, and thoughts. These are just some of the findings of the most extensive survey of meditators ever conducted on the experience of pure consciousness. The findings of the survey recently have been published in PLOS ONE.

TORONTO, ON - Researchers at the University of Toronto have developed an innovative tool to aid in the investigation of how we perceive and remember visual experiences.

The new tool, referred to as a "scene wheel," will help researchers study how accurately we construct mental representations of visual experiences for later retrieval -- for example, how well an eyewitness recalls details of a crime or accident.

Natto, a fermented soybean dish often served for breakfast in Japan, originated at the turn of the last millennium but may hold an answer to a modern problem: COVID-19, according to a new study based on cell cultures.
