Mobile phones, smartwatches and earbuds are some gadgets that we carry around physically without much thought. The increasingly digitalised world sees a shrinking gap between human and technology, and many researchers and companies are interested in how technology can be further integrated into our lives.   What if, instead of incorporating technology into our physical world, we assimilate ourselves into a virtual environment? This is what Assistant Professor Xiong Zehui from the Singapore University of Technology ...

The research teams of Professor René Ketting at the Institute of Molecular Biology (IMB) in Mainz, Germany, and Dr. Sebastian Falk at the Max Perutz Labs in Vienna, Austria, have identified a new enzyme called PUCH, which plays a key role in preventing the spread of parasitic DNA in our genomes. These findings may reveal new insights into how our bodies detect and fight bacteria and viruses to prevent infections. Our cells are under constant attack from millions of foreign intruders, such as viruses and bacteria. To keep us from getting sick, ...

UVA Health researchers have developed a powerful new tool to understand how medications affect men and women differently, and that will help lead to safer, more effective drugs in the future. Women are known to suffer a disproportionate number of liver problems from medications. At the same time, they are typically underrepresented in drug testing. To address this, the UVA scientists have developed sophisticated computer simulations of male and female livers and used them to reveal sex-specific differences in how the tissues are affected by drugs. The new model has already provided ...

Using zebrafish as a model, investigators have determined a suitable combination of chemical compounds in which to store hearts, and potentially other organs, when frozen for extended periods of time before transplantation. The work, which is published in The FASEB Journal, involved a variety of methods, including assays at multiple developmental stages, techniques for loading and unloading agents, and the use of viability scores to quantify organ function. These methods allowed scientists to perform the largest and most comprehensive screen of cryoprotectant agents to determine their toxicity and efficiency at preserving ...

Osaka, Japan - Circadian rhythms, the internal biological clocks that regulate our daily activities, are essential for maintaining health and well-being. While the role of transcription in these rhythms is well-established, a new study sheds light on the critical importance of post-transcriptional processes. The research, titled “Circadian ribosome profiling reveals a role for the Period2 upstream open reading frame in sleep,” to be published in PNAS, redefines our understanding of how translation and post-transcriptional processes influence the body’s internal clock and its impact on sleep patterns. Timing Is Everything: ...

Osaka, Japan – Memory B cells depend on autophagy for their survival, but the protein Rubicon is thought to hinder this process. Researchers from Osaka University have discovered a shorter isoform of Rubicon called RUBCN100, which enhances autophagy in B cells. Mice that lacked the longer isoform, RUBCN130, produced more memory B cells in a way that relied on autophagy. These findings provide further insight into the role of Rubicon in autophagy. Autophagy is a mechanism that degrades and ...

Until recently, our understanding of Parkinson's disease has been quite limited, which has been apparent in the limited treatment options and management of this debilitating condition. Our recent understanding has primarily revolved around the genetic factors responsible for familial cases, while the causative factors in the vast majority of patients remained unknown. However, in a new study, researchers from the University of Copenhagen have unveiled new insights into the workings of the brain in Parkinson's patients. Leading the groundbreaking discovery is Professor Shohreh Issazadeh-Navikas. “For the first time, we can show that mitochondria, ...

Predation is a driving force in the evolution of anti-predator strategies, and death feigning, characterized by immobility in response to threats, is a common defensive mechanism across various animal species. While this behavior can enhance an individual's survival prospects by reducing a predator's interest, it also carries costs, such as limited opportunities for feeding and reproduction. Recently, researchers from Okayama University, Japan, investigated how pheromones, important chemical signals that affect foraging and reproduction, might influence death-feigning behavior in the red flour beetle, Tribolium castaneum.  “Male beetles release an aggregation pheromone called ...

Genetic quality or genetic compatibility? What do female fruit flies prioritize when mating? Researchers at the University of Zurich show that both factors are important at different stages of the reproductive process and that females use targeted strategies to optimize the fitness of their offspring. Breeding female fruit flies face a difficult decision: do they mate with the male that has the best genes, or with the one whose genes best match their own? Evolutionary biologists from the University of Zurich and Concordia University have now investigated ...

Identifying the underlying cause of extreme events such as floods, heavy downpours or tornados is immensely difficult and can take a concerted effort by scientists over several decades to arrive at feasible physical explanations. Extreme events cause significant deviation from expected behavior and can dictate the overall outcome for a number of scientific problems and practical situations. For example, practical scenarios where a fundamental understanding of extreme events can be of vital importance include rogue waves in the ocean that could endanger ships and offshore structures or increasingly ...

A breakthrough study, jointly led by Professor Jang Hyun Choi and Professor Sung Ho Park from the Department of Biological Sciences at UNIST has identified an important factor involved in the development of non-alcoholic fatty liver disease (NAFLD) caused by obesity. The research team discovered that Thrap3, a protein associated with thyroid hormone receptors, plays a significant role in exacerbating NAFLD by inhibiting the activity of adenosine monophosphate-activated protein kinase (AMPK), a key regulator of fat metabolism in the liver. NAFLD encompasses various metabolic diseases such as fatty hepatitis and cirrhosis resulting from excessive fat accumulation. ...

Lower income breast cancer patients often struggle to afford life’s necessities such as housing, transportation and utilities due to direct and incidental costs related to their treatment, according to a new analysis by Susan G. Komen®, the world’s leading breast cancer organization. These top needs were identified by Susan G. Komen’s Patient Care Center, which provided nearly $9.1 million in grants to more than 16,000 breast cancer patients from April 1, 2022 to March 31, 2023, as part of Komen’s direct-to-patient ...

A group of international collaborators led by the Research Institute for Humanity and Nature (RIHN) team performed the first quantitative study of air pollution in the north-western India region using 29 low-cost and reliable instruments, demonstrating the advantages of source region observations to link crop residue burning (CRB) and air pollution at local to regional scales.  Exposure to particulate matter less than 2.5 µm in diameter (popularly known as PM2.5) causes health hazards in cities and major emission regions of the world. Although the major sources ...

Osaka, Japan – Will printed photographs ever match the precision of a mirror's reflection? Even though the answer may still be no for a while, Osaka Metropolitan University scientists have made significant strides in precision printing with their innovative optical vortex laser-based technique that allows for the precise placement of minuscule droplets with micrometer-scale accuracy. Inkjet technology is a well-known printing technique that emits microdroplets from a nozzle directly onto a surface. However, when the ink droplets are viscous, with high density, ...

HPV, or human papillomavirus, is the most common sexually transmitted infection. It is also the leading cause of cervical cancer. Over 1,400 Canadian women are affected yearly, with almost 400 deaths, according to the Canadian Cancer Society. It is completely preventable with the HPV vaccine, and yet, unfortunately, many people are unvaccinated. University of Waterloo researchers have found a possible solution to this on-going issues. Using an electronic questionnaire at the time of appointment scheduling for seasonal influenza or COVID-19 vaccines, researchers have found, is a quick and efficient way to identify people in Ontario willing to receive additional life-saving vaccines.  “This ...

By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization. Nearly half the embryos studied underwent developmental arrest   because of genetic mishaps in early development — a revealing insight that suggests more IVF babies could come to term with changes in the fertility treatment process. The unique combination of data from arrested embryos also sheds new light on the still largely mysterious earliest stages of pregnancy through natural ...

SAN DIEGO, October 1, 2023 — The presence of a clinical navigator to act as a liaison between people with prostate cancer and the health care system greatly increases the likelihood that patients, especially Black patients, will receive advanced testing that can help predict the severity of their disease and guide treatment, a new study suggests. The study showed patients seen by a precision medicine navigator were substantially more likely to receive genomic testing than those not seen by the navigator. Black patients, whose genomic testing rates traditionally ...

Dr Jacqueline Harding, director of Tomorrow’s Child and an early childhood expert at Middlesex University, argues that the young child’s brain is inherently designed to be playful and this is crucial for its development. In her new book, The Brain that Loves to Play, she challenges the traditional division between play and learning, emphasizing the essential role of play in early years education and holistic child development. With a renewed vision for the fusion of play and learning, the book aims to contribute to the ...

Faith primary schools are admitting fewer children with special educational needs and disabilities (SEND) than local authority community primaries, according to new research from the London School of Economics and Political Science (LSE). In research funded by the British Academy, Dr Tammy Campbell analysed Reception year admissions to mainstream state schools from 2010-2020 in England using the National Pupil Database census.  She concluded that many faith primary schools ‘serve as hubs of relative advantage, seeming disproportionately to serve ...

New research being presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Hamburg, Germany (2-6 Oct) has found that severe hypoglycaemia is more than twice as common among adults with diabetes who struggle to afford food. Severe hypoglycaemia occurs when a person’s blood sugar levels fall to such an extent that it can cause loss of consciousness, seizures, coma and, in rare cases, death. Severe hypoglycaemia is rare in people with diabetes unless they are taking insulin or secretagogues – two commonly prescribed ...

New research being presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Hamburg, Germany (2-6 Oct) has linked infant formula and the early introduction of fizzy drinks with higher levels of body fat later in childhood.   Youngsters who were breastfed for at least six months or longer had a lower percentage of body fat by age nine compared to those who did not receive breast milk for six months (a group that includes children who were never breastfed or received breast milk for less than 6 months).   Children ...

Exposure to natural light could help treat and prevent type 2 diabetes, new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Hamburg, Germany (2-6 Oct), suggests. “The misalignment of our internal circadian clock with the demands of a 24/7 society is associated with an increased incidence of metabolic diseases, including type 2 diabetes,” says Ivo Habets, of Maastricht University, Maastricht, the Netherlands, who co-led the research.  “Natural daylight is the strongest zeitgeber, or environmental cue, of the circadian ...

Boston – Researchers at Dana-Farber Brigham Cancer Center have found that a shorter course of radiation therapy after mastectomy and breast reconstruction surgery provides the same protection against breast cancer recurrence and equivalent physical side-effects but substantially reduces life disruption and financial burden for patients. The results of the multicenter randomized clinical trial – the FABREC Study (Hypofractionated versus Conventionally Fractionated Postmastectomy Radiation Therapy After Implant-Based Reconstruction) – were presented ...

SAN DIEGO, October 1, 2023 — In a first-of-its-kind study, people with breast cancer who underwent implant-based breast reconstruction immediately following a mastectomy reported that getting fewer, higher doses of radiation was just as effective as standard radiation, did not increase side effects and saved them time and money. There also was a small improvement in quality of life for women under 45 who received the shortened treatment regimen. The FABREC study is the first prospective randomized study comparing quality-of-life and clinical outcomes following accelerated versus conventional radiation therapy specifically for patients with ...

SAN DIEGO, October 1, 2023 — People who engage in sexual activity or vaginal dilation after chemoradiation treatment for cervical cancer are at lower risk for long-term side effects, according to a new study from researchers in Austria. Findings of the EMBRACE study will be presented today at the American Society for Radiation Oncology (ASTRO) Annual Meeting.  “Curing cancer is always our first priority,” said lead study author Kathrin Kirchheiner, MSc, PhD, a clinical psychologist in the department of radiation oncology at the Medical University of Vienna. “But with a growing number of relatively young cervical cancer survivors, ...
