Patients and families affected by food allergy worry when they fly and often make travel decisions with food allergy management top-of-mind Airlines don’t always honor buffer zones, allergen-free food or cabin announcements that were promised to travelers during the booking process  Simple steps to help ensure the safety of travelers with food allergy can go a long way CHICAGO ---The skies aren’t always so friendly for patients and families affected by food allergies, who may often experience worry and anxiety regarding airline travel, according to a new study from the Center for Food Allergy and Asthma Research at Northwestern University ...

More images and video available- see link in the Notes section. A new study suggests that the fundamental abilities underlying human language and technological culture may have evolved before humans and apes diverged millions of years ago. The findings will be published 5th December 2024 in the journal PeerJ. Many human behaviours are more complex than those of other animals, involving the production of elaborate sequences (such as spoken language, or tool manufacturing). These sequences include the ability to organise behaviours by hierarchical chunks, and to understand relationships between distantly separated elements. For example, even relatively simple human behaviours like making ...

PULLMAN, Wash. – Analysis of cheek swabs taken from pregnant women revealed a potential epigenetic biomarker for preeclampsia, a potentially life-threatening condition that often leads to preterm births. While a clinical trial is needed to confirm the results, a study published in the journal Environmental Epigenetics offers hope that a simple test can be developed to identify preeclampsia earlier in pregnancy. Currently preeclampsia is usually identified by symptoms, such as abnormally high blood pressure, which only appear in the second trimester of pregnancy. Sometimes the condition can go undetected ...

CHICAGO – More than a third of women across 10 health care practices chose to enroll in a self-pay, artificial intelligence (AI)-enhanced breast cancer screening program, and the women who enrolled were 21% more likely to have cancer detected, according to research being presented today at the annual meeting of the Radiological Society of North America (RSNA). AI has shown great promise in mammography as a “second set of eyes” for radiologists providing decision support, risk prediction and other benefits. Despite its promise, AI is not yet reimbursed by insurance, which likely is slowing its adoption ...

We all need to eat, but the impact of the climate crisis on our crops is throwing the world’s food supply into question. Modern crops, domesticated for high food yields and ease of harvesting, lack the genetic resources to respond to the climate crisis. Significant environmental stresses are reducing the amount of food produced, driving supplies down and prices up. We can’t sustainably take over more land for agriculture, so we need to change our crops—this time to adapt them to the world we have altered. “Agriculture is highly vulnerable to climate change, and the intensity and frequency of extreme events is only going to increase,” said Prof Sergey ...

— By Michael Matz The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated a machine-learning technique to accelerate discovery of materials for film capacitors — crucial components in electrification and renewable energy technologies. The technique was used to screen a library of nearly 50,000 chemical structures to identify a compound with record-breaking performance. The other collaborators from University of Wisconsin–Madison, Scripps Research Institute, University of California, ...

Researchers from Max Planck Florida Institute for Neuroscience have discovered a new pathway to forming long-term memories in the brain. Their work suggests that long-term memory can form independently of short-term memory, a finding that opens exciting possibilities for understanding memory-related conditions. A New Perspective on Memory Formation Our brain works diligently to record our experiences into memories, creating representations of our daily events that stay with us for short time periods. Current scientific theories of memory formation suggest that short-term memories are stored in what we can imagine as a temporary art exhibition in our ...

• A research team led by the UAB has made exceptional discoveries on prehistoric archery from the early Neolithic period, 7,000 years ago. • The well organic preservation of the remains of the Cave of Los Murciélagos in Albuñol, Granada, made it possible for scientists to identify the oldest bowstrings in Europe, which were made from the tendons of three animal species. • The use of olive and reed wood and birch bark pitch in the making of arrows reveals an unprecedented degree of precision and technical mastery, as highlighted in the study, published in Scientific Reports. ...

TORONTO - New research published by a team of researchers from the University of Toronto in collaboration with colleagues from the University of Alberta has found that women who have had both ovaries surgically removed before the age of 50 and carry a variant of the apolipoprotein gene, the APOE4 allele, are at high risk of late-life Alzheimer disease (AD).  Use of hormone therapy mitigates this risk. Why does this matter? By 2050, Alzheimer’s disease is projected to affect 12.7 million individuals 65 and older with women comprising two-thirds of that number. It is still unclear why Alzheimer’s disease is more prevalent in women than in men, but it may have to do with ...

BALTIMORE, Dec. 5, 2024:  Obesity affects a staggering 40 percent of adults and 20 percent of children in the United States. While some new popular therapies are helping to tackle the epidemic of obesity, there is still so much that researchers do not understand about the brain-body connection that regulates appetite. Now, researchers have discovered a previously unknown population of neurons in the hypothalamus that regulate food intake and could be a promising new target for obesity drugs. In a study published in the Dec. 5 issue of Nature, a team of researchers from the Laboratory ...

When a forest is lost to development, some effects are obvious. Stumps and mud puddles across the landscape, a plowed field or houses a year after that. But deforestation isn’t just a loss of trees; it’s a loss of the countless benefits that forests provide—one of which is control of disease. Now, a startling new global study shows that a widespread malaria-fighting strategy—bed nets—becomes less effective as deforestation rises. The research underscores how important a healthy environment can be for human health. Insecticide-treated ...

Polarization photodetectors (pol-PDs) have widespread applications in geological remote sensing, machine vision, and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniaturize and integrate. Chinese researchers have recently made important progress in this area by developing an on-chip integrated polarization photodetector. This study, published in Science Advances on Dec. 4, was conducted by Prof. Li Mingzhu’s group from the Technical ...

Researchers from Singapore and China have used a superconducting quantum processor to study the phenomenon of quantum transport in unprecedented detail. A better understanding of quantum transport, which can refer to the flow of particles, magnetisation, energy or information through a quantum channel, could propel advances in technologies such as nanoelectronics and thermal management. “We’re quite excited because this is, practically, a new paradigm of doing quantum transport experiments,” says Centre for Quantum Technologies (CQT) Fellow Dario Poletti, whose co-corresponding authors for the new work published in Nature ...

An international team of researchers including The University of Tokyo Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) has found evidence showing that old elliptical galaxies in the universe can form from intense star formation within early galaxy cores. This discovery will deepen our understanding of how galaxies evolved from the early Universe, reports a new study in Nature. Galaxies in today’s Universe are diverse in morphologies and can be roughly divided into two categories: younger, disk-like spiral galaxies, ...

Bamboo invasion has been widely observed across Asia (e.g., China, Japan, and India), North America, South America (e.g., Brazil and Peru) and Africa. Moso bamboo (Phyllostachys edulis), a large-running bamboo species native to subtropical China, is known for its invasive nature and ability to encroach upon adjacent communities, particularly derived forests. While some plot-based studies exist, our understanding of how forest structural dynamics and diameter–height allometric relationships respond to bamboo invasion has remained limited. In a study published in the KeAi journal Forest Ecosystems, researchers from China ...

Developing reliable methods to replace dead or damaged tissue is one of the primary goals of regenerative medicine. With steady advances in tissue engineering and biomedicine, we are almost at a point where growing cell sheets in the lab and transplanting them onto damaged or diseased organs is becoming a reality rather than fiction. Notably, myoblast cell sheets have already been used to successfully treat severe heart failure, demonstrating the potential of this technology. However, there are still a few unsolved challenges ...

Earth's tropical rain belt, responsible for monsoons that sustain billions of people and vibrant ecosystems, has long been a reliable feature of the planet's climate. But new research reveals this vital system wasn't always so dependable. A study published in Geophysical Research Letters shows that during the early Eocene—the hottest period in the last 65 million years—the rain belt's seasonal shifts weakened dramatically. These ancient changes could offer critical warnings about the impact of modern global warming. A Greenhouse Climate 50 Million Years ...

Rice paddies, responsible for approximately 10% of global anthropogenic methane (CH₄) emissions, are increasingly recognized as a key contributor to global warming. Reducing emissions from rice cultivation is essential to achieving international climate goals, especially in light of commitments to carbon neutrality and peak emissions targets. A team led by Prof. LI Tingting from the Institute of Atmospheric Physics at the Chinese Academy of Sciences has validated an independently developed methane emission model, CH4MOD, at the global scale. This research highlights the advantages of process-based models over the commonly ...

Women who experience infertility but do not use fertility treatments have a higher risk of developing a group of conditions called systemic autoimmune rheumatic diseases (SARD) in the nine years after a naturally conceived birth compared to women without fertility problems.   The new research, published today (Thursday) in Human Reproduction [1], one of the world’s leading reproductive medicine journals, found that this was true even after accounting for higher rates of pre-eclampsia (high blood pressure during pregnancy), preterm birth ...

Colorful auroras appeared around Japan's Honshu and Hokkaido islands on May 11, 2024, sparked by an intense magnetic storm. Usually, auroras observed at low latitudes appear red due to the emission of oxygen atoms. But on this day, a salmon pink aurora was observed throughout the night, while an unusually tall, blue-dominant aurora appeared shortly before midnight.   Smartphone videos and amateur photos captured the event, enabling scientists to combine public data with their own research and study the phenomenon.   In a ...

Higher rates of certain cancers in countries, such as the UK, may be linked to two particular strains of bacteria. Targeting these with treatments or vaccines could help reduce the risk of colorectal, bladder, and prostate cancers. Researchers from the Wellcome Sanger Institute, the University of Helsinki, and collaborators investigated the differences in cancer incidence for colorectal, bladder and prostate cancers, and compared these to global data tracking Escherichia coli (E.coli) strains. Specifically, they looked at the dominant two E.coli strains that produce a substance that has been previously identified as a risk factor for colorectal cancer. Their ...

Embargoed for release: Wednesday, Dec. 4, 6:30 PM ET Key points: Study participants who consumed at least five servings of any chocolate per week showed a 10% lower risk of type 2 diabetes (T2D) compared to those who rarely or never ate chocolate. Dark chocolate had an even bigger impact: Participants who consumed at least five servings of this chocolate per week showed a 21% lower risk of T2D. Consumption of milk chocolate, but not dark chocolate, was not associated with T2D risk; it was associated ...

Eating five servings of dark chocolate a week is associated with a reduction in the risk of type 2 diabetes, according to a long-term US study published by The BMJ today. Global rates of type 2 diabetes are set to rise to 700 million by 2045. Chocolate contains high levels of flavanols (a natural compound found in fruits and vegetables) which have been shown to promote heart health and reduce the risk of type 2 diabetes. But the link between chocolate consumption and risk of type 2 diabetes remains controversial due to inconsistent results. In addition, most previous studies have not looked at whether eating dark and milk chocolate – which have different ...

An investigation published by The BMJ today reveals widespread influence of food and drink brands in schools and nurseries – through breakfast clubs, nutrition guidance, and healthy eating campaigns - while rates of obesity in the UK have worsened. Experts say the tactics are “subtle but very problematic” and require much greater scrutiny and pushback. Organisations influencing food provision and education in schools include Kellogg’s, Greggs, Nestle, and the British Nutrition Foundation, a “policy development” charity ...
