Researchers from University of British Columbia published a new paper in the Journal of Marketing that examines whether and how the use of 'ugly' labeling for unattractive produce increases sales and profit margins. The study, forthcoming in the Journal of Marketing, is titled "From Waste to Taste: How "Ugly" Labels Can Increase Purchase of Unattractive Produce" and is authored by Siddhanth (Sid) Mookerjee, Yann Cornil, and JoAndrea Hoegg. According to a recent report by the National Academies of Science, Engineering and Medicine (2020), each year in the U.S. farmers throw away up to 30% of their crops, equal to 66.5 million tons of edible produce, ...

WEST LAFAYETTE, Ind. - New technology from Purdue University and Indiana University School of Medicine innovators may one day help patients who suffer devastating vocal injuries from surgery on the larynx. A collaborative team consisting of Purdue biomedical engineers and clinicians from IU has tissue-engineered component tissue replacements that support reconstruction of the larynx. The team's work is published in The Laryngoscope. The larynx is a very complex human organ consisting of outer cartilage for structural support, inner muscle that contracts to permit voicing, swallowing, and breathing, and inner vibratory lining. Currently, thousands of patients each year with laryngeal cancer ...

RICHLAND, Wash. - No one went to Oktoberfest in 2020, but chances are those who attended in the past are still thinking about it. In a case study of the famous German beer festival, researchers tested the theory that events which create memorable experiences can increase life-satisfaction. This deep connection with customers has big benefits for associated businesses, according to Robert Harrington, lead author of the study recently published online in the International Journal of Contemporary Hospitality Management. "If you can do something that transforms people even a little bit, it can have a huge impact on the success of your company and your brand," said Harrington, professor and director of the School ...

A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition which affects up to a quarter of the world's population. The researchers, from the University of Cambridge, used modelling and high-speed video techniques to show what causes wheezing and how to predict it. Their results could be used as the basis of a cheaper and faster diagnostic for lung disease that requires just a stethoscope and a microphone. Improved understanding of the physical mechanism responsible for generating wheezing sounds could provide a ...

A team of researchers concludes that a game-theory approach may offer new insights into both the spread and disruption of viruses, such as SARS-CoV-2. Its work, described in the journal Royal Society Interface, applies a "signaling game" to an analysis of cellular processes in illuminating molecular behavior. "We need new models and technologies at many levels in order to understand how to tame viral pandemics," explains Bud Mishra, a professor at NYU's Courant Institute of Mathematical Sciences and one of the paper's authors. "At the biomolecular level, we explain how cellularization may be understood in ways that stymie disease and encourage healthy functioning." The analysis, which also included William Casey, ...

A new study involving researchers from the University of Oxford and the Chinese Center for Disease Control and Prevention (China CDC) has examined the change in overall and cause-specific death rates during the three months of the COVID-19 outbreak in early 2020. The results are published today in The BMJ. In China, the emergence of COVID-19 was first reported during mid-December 2019 in Wuhan city, Hubei province. Coinciding with the January 2020 festivities for the Chinese Lunar New Year, the virus spread rapidly across China. This led to a national lockdown on 23 January 2020, which continued until early April. The ...

Night 'owls' may be twice as likely as morning 'larks' to underperform at work and to run a heightened risk of early retirement due to disability, finds research published online in the journal Occupational & Environmental Medicine. Given the move to lengthen working life and delay pension eligibility, it might be worth factoring in a person's chronotype, suggest the researchers. Morning chronotypes, or 'larks' tend to do better early in the morning, while evening chronotypes, or 'owls' do better in the evening. Chronotype is largely genetic, but environmental factors, such as exposure to daylight, work schedules, and family life can also influence it. Owls don't usually fall asleep early enough to get the recommended 7+ hours of sleep on ...

A whole foods, plant based diet may ease the painful skin blistering and scarring of a baffling blood vessel disorder for which there is as yet no commonly accepted cure, and no known cause, suggest doctors in the journal BMJ Case Reports. The primary symptoms of livedoid vasculopathy are extremely painful ulcers of varying sizes on the feet and lower legs, which leave visible scars when healed. The condition affects 1 in 100,000 people, mostly women in their 30s. The symptoms can last for months to years and can recur. Poor blood flow is often associated with the condition, but the exact cause remains a mystery, and there is as yet no commonly accepted cure, note the authors. They report the case of a woman in her early 60s, whose symptoms had first started in 2006. In 2013 ...

Unique analysis of US county-level data finds a strong association between jail incarceration and death rates at the county level from infectious diseases, chronic lower respiratory disease, drug use, and suicide; and to a lesser extent heart disease and cancer. Findings underscore public health benefits of reducing jail incarceration and importance of interventions to mitigate the harmful effects of mass imprisonment on community health including treatment for substance use disorder and greater investment in social services. County jail incarceration rates in the USA are potential drivers of many causes of death in the communities where they are located, with particularly pronounced effects on the number of deaths caused by infectious and respiratory diseases, drug overdose, and suicide, ...

A new study has discovered that not all cockroaches are equal and "super athletes", with larger respiratory systems, are more likely to win physical mating battles. The research, published in the journal Animal Behaviour and led by Dr Sophie Mowles of Anglia Ruskin University (ARU), studied aggressive interactions between male wide-horned hissing cockroaches (Gromphadorhina oblongonota). Animal contests are usually won by the larger opponent and physical fighting is often avoided if clear differences exist between competitors. However, during a series of laboratory contests, the researchers closely matched the cockroaches ...

International travellers are particularly vulnerable to virulent strains of drug-resistant bacteria - often picking up several different types during a trip through spending time in the company of other tourists, a new study reveals. The global spread of intestinal multidrug resistant gram-negative (MDR-GN) bacteria poses a serious threat to human health worldwide, with MDR clones of E.coli and Klebsiella pneumoniae threatening more antibiotic resistant infections around the world. Researchers monitored a group of European travellers visiting Lao People's Democratic Republic for three weeks - analysing daily returns of ...

An analysis of U.S. county-level data found a strong association between jail incarceration and death rates from infectious diseases, chronic lower respiratory disease, drug use, and suicide, in a new study by Columbia University Mailman School of Public Health. The researchers found this was the case to a lesser extent for heart disease and cancer. The study is the first to examine the link between the expansion of the jail population and multiple specific causes of death at the county level, and adds to the growing body of evidence suggesting that decarceration strategies would improve public health. Findings are published online in the journal Lancet ...

Highlight Racial disparities in access to kidney transplantation persist in the United States. New research indicates that registering Black patients on the kidney transplant waitlist at a slightly higher level of kidney function compared with white patients might lessen racial inequality in patients' wait time prior to kidney failure onset, and ultimately improve racial equity in access to kidney transplantation. Washington, DC (February 23, 2021) -- Despite efforts to address them, racial disparities in access to kidney transplantation persist in the United States. New research published in an upcoming issue of JASN indicates that policy changes surrounding patients' eligibility to be put on kidney transplant waitlists might help address these disparities. There are studies ...

MINNEAPOLIS - More than two-thirds of people with migraine do not get enough exercise, according to a preliminary study released today, February 23, 2021, that will be presented at the American Academy of Neurology's 73rd Annual Meeting being held virtually April 17 to 22, 2021. The study found that people who do get a minimum of two-and-a-half hours of moderate to vigorous exercise a week had a reduced rate of migraine triggers like stress, depression and sleep problems. "Migraine is a disabling condition that affects millions of people in the United States, and yet regular exercise may be an effective way to reduce the frequency and intensity of some migraines," said study author Mason Dyess, D.O., of the University ...

One in four women over age 65 is unable to walk two blocks or climb a flight of stairs. Known as mobility disability, it is the leading type of incapacity in the United States and a key contributor to a person's loss of independence. New research from Herbert Wertheim School of Public Health and Human Longevity Sciences at UC San Diego suggests that light-intensity physical activity, including shopping or a casual walk, may protect mobility in older women. Published in the February 23, 2021 online issue of JAMA Network Open, researchers found that women ...

Texas A&M University researchers have designed a reinforcement-based algorithm that automates the process of predicting the properties of the underground environment, facilitating the accurate forecasting of oil and gas reserves. Within the Earth's crust, layers of rock hold bountiful reservoirs of groundwater, oil and natural gas. Now, using machine learning, researchers at Texas A&M University have developed an algorithm that automates the process of determining key features of the Earth's subterranean environment. They said this research might help with accurate forecasting of our natural reserves. Specifically, the researchers' algorithm ...

Isn't it convenient when office building windows adaptively darken according to the intensity of sunlight? Or when standard glasses turn into sunglasses under the sun and switch back as you enter a building? Such feats are possible thanks to photochromic materials, whose optical (and other) properties change radically when irradiated by visible or ultraviolet light. Today, virtually all fast-switching photochromic materials are made using organic compounds. Unfortunately, this makes them considerably expensive and complex to synthesize, requiring multi-step processes that are difficult to scale up for mass production. So, despite the myriad ...

Thuwal/Helsinki/Leipzig. Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities. An international research team has now been able to prove this through laboratory experiments with state-of-the-art measurement technology at the University of Helsinki and the Leibniz Institute for Tropospheric ...

LOS ALAMOS, N.M., February 23, 2021--A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described in this week's Nature Communications journal. This automated approach to "interatomic potential development" could transform the field of computational materials discovery. "This approach promises to be an important building block for the study of materials damage and aging from first principles," said project lead Justin Smith of Los Alamos National Laboratory. "Simulating the dynamics of interacting atoms is a cornerstone of understanding and developing new materials. Machine learning methods are providing computational scientists new tools to accurately and efficiently conduct these atomistic ...

Neuroblastoma is a cancer that develops in nerve tissue, most commonly in the glands around the kidneys. The gene MYCN is overexpressed in 20-25% of neuroblastoma, and MYCN-amplified neuroblastoma contributes to a considerable percentage of pediatric cancer-related deaths. Anthony Faber, Ph.D., and a team of researchers at VCU Massey Cancer Center were awarded a grant from the American Cancer Society to study how MYCN and an abundance of iron can drive cancer cell death in neuroblastoma and potentially be targeted with novel treatments. This award is the first part of a potential two-stage grant worth a combined total of $600,000. "Iron is a double-edged sword in a cancer cell. It can help the cancer grow and survive, but it also creates ...

Schizophrenia, a chronic, neurological brain disorder, affects millions of people around the world. It causes a fracture between a person's thoughts, feelings and behavior. Symptoms include delusions, hallucinations, difficulty processing thoughts and an overall lack of motivation. Schizophrenia patients have a higher suicide rate and more health problems than the general population, and a lower life expectancy. There is no cure for schizophrenia, but the key to treating it more effectively is to better understand how it arises. And that, according to Ryuta Mizutani, professor of applied biochemistry at Tokai University in Japan, means studying the structure of brain tissue. Specifically, it means comparing the brain tissues of schizophrenia patients with those ...

Even as more people are logging onto popular video chat platforms to connect with colleagues, family and friends during the COVID-19 pandemic, Stanford researchers have a warning for you: Those video calls are likely tiring you out. Prompted by the recent boom in videoconferencing, communication Professor Jeremy Bailenson, founding director of the Stanford Virtual Human Interaction Lab (VHIL), examined the psychological consequences of spending hours per day on these platforms. Just as "Googling" is something akin to any web search, the term "Zooming" has become ubiquitous and a generic verb to replace videoconferencing. Virtual meetings have skyrocketed, with hundreds of millions happening daily, as social distancing protocols have kept people apart physically. In ...

Biologically active compounds from the marine fungus Penicillium dimorphosporum protect cells from paraquat, the highly toxic herbicide with no remedy, and might enhance the action of some drugs. The fungus was isolated from soft coral collected in the South China Sea during an expedition on the Akademik Oparin research vessel. Scientists of Far Eastern Federal University (FEFU) and G. B. Elyakov Pacific Institute of Bioorganic Chemistry reported the results in Marine Drugs. Paraquat a herbicide compound highly toxic for animals and humans. About a hundred countries, including the United States, apply it for crop cultivation and weed control. Dozens of countries, including Russia, have banned the ...

A new research study out of the University of Nevada, Reno's School of Community Health Sciences has just been published by the American Journal of Public Health and addresses state preemption of local sugar-sweetened beverage (SSB) taxes, issuing an emerging public health threat. Assistant Professor Eric Crosbie examines commercial determinants of health and public health policy, specifically in industries like tobacco and food and beverage. "The beverage industry is aggressively attempting to preempt sugar-sweetened beverage taxes at the state level to prevent the diffusion of progressive policies at the local level throughout the United States," Crosbie, an affiliate of the University's Ozmen Institute for Global Studies, said. "Once preemption laws are enacted, ...

There is growing evidence that ketone bodies may be beneficial to heart disease patients regardless of the method of delivery used to increase ketone delivery to the heart. A Journal of the American College of Cardiology review paper examines emerging evidence regarding ketone bodies' effects on the heart and the potential for ketone therapy as a cardiovascular intervention in heart disease patients. In recent years ketone bodies entered the popular lexicon through the "keto diet," which consists of a very low carbohydrate and high fat diet that endeavors to force the body into ketosis. This is a metabolic ...
