The Daniels Lab at the Florida Museum of Natural History was recently awarded two grants to help support pollinators in Florida. The Florida Department of Transportation has set aside $155,002 for the team to plant and monitor thousands of milkweeds along roads in North Florida, and Duke Energy Florida will distribute $144,421 over three years to evaluate the establishment of pollinator habitat at its new solar site Alachua County. Pollinators are declining on a global scale, the collateral damage of continued habitat destruction and urbanization, among other stressors. ...

For decades, corn and soy farmers have heavily relied on one herbicide: glyphosate. Crops bred to resist glyphosate have been extremely successful, with over 90% of corn and soy hectares planted with glyphosate-resistant varieties by 2014. But as Christopher Landau and colleagues document, the chemical was not quite the “silver bullet” it was promised to be. With an entire industry using the same chemical—the US and Canada alone apply more than 130 million kg annually—evolutionary selection pressures on weed plants have been intense. Since 1996, there have been 354 confirmed cases of glyphosate ...

In a study on fruit flies, daily low-intensity blue light exposure (BLE), similar to that experienced daily by billions of humans in the form of LED lighting and device screens, changed flies at the sub-cellular level, affecting processes related to aging and circadian rhythms. Xiaoyun Wang and colleagues exposed fruit flies (Drosophila melanogaster) to different durations of daily low-intensity BLE and then analysed the consequences to the cellular makeup of the insects, as compared to flies raised in darkness. The authors paid particular attention to ...

A study links hostility on Wikipedia to lost productivity on the site. Wikipedia, the largest reference work ever created, is written and edited by tens of thousands of volunteers, known as Wikipedians. Despite the fact that anyone can edit any page, studies show that Wikipedia is generally a reliable source of information. Ivan Smirnov and colleagues studied how the volunteer labor that keeps the site working is affected by hostile comments in the “user talk” pages connected to each editor. Toxic comments were identified by a toxicity detection algorithm devised by the Perspective API ...

Hamilton, ON, December 5, 2023 – There is no shortage of advice for women on what to eat, how to train, or what supplements to take during their menstrual cycles, but a new review by an international team of scientists has found little evidence to support such recommendations. In fact, they found sparse research on women and exercise at all, and even less on the effect of their periods on sports performance, physiology, or physical fitness. The authors of the paper, from McMaster University, Manchester Metropolitan University and the Australian Catholic University in Melbourne, are calling for much more high quality, standardized research ...

Brussels, 5 December 2023 – In a report launched today at a lunch debate hosted by Deirdre Clune MEP (Ireland), Alzheimer Europe highlighted the continuing inequalities in access to dementia care and treatment across Europe. The objective of the report entitled “European Dementia Monitor” was to provide a benchmark of national dementia policies in order to compare and rate the responses of European countries to the dementia challenge. The survey covered all Member States of the European Union (with the exception of Latvia), as well as Armenia, Iceland, Israel, Jersey, North Macedonia, Norway, Serbia, Switzerland, Turkey, United ...

Despite an end to the national public health emergency in May 2023, the use of telehealth remains high, with over 20% of American adults taking appointments online. These visits include video calls with registered dietitian nutritionists, who have a critical role in helping patients take on lifestyle changes through medical nutrition therapy. With a focus on the changing digital landscape, researchers at Michigan Medicine found that telemedicine patients with hyperlipidemia — an excess of cholesterol or fats in the blood ...

VANCOUVER, Wash. – Seeing robots made with soft, flexible parts in action appears to lower people’s anxiety about working with them or even being replaced by them. A Washington State University study found that watching videos of a soft robot working with a person at picking and placing tasks lowered the viewers’ safety concerns and feelings of job insecurity. This was true even when the soft robot was shown working in close proximity to the person. This finding shows soft robots hold ...

New research from Scripps and NOAA scientists has discovered ecological correlations that could help explain the booms and busts of California’s anchovy population. If the correlations hold up to further research, they could one day help inform management of California’s anchovy fishery and improve conservation. The Northern Anchovy (Engraulis mordax) is a crucial food source for much of California’s most conspicuous marine life – including droves of sea lions, pods of dolphins, lucrative tuna fisheries, and throngs of whales. But one of the hallmarks of the anchovy population off California ...

The results are just published in Nature Communications under the title "Enhanced production of mesencephalic dopaminergic neurons from lineage-restricted human undifferentiated stem cells." In the new research findings, DANDRITE group leader and Associate Professor Mark Denham has developed a method that ensures much higher purity of the so-called dopamine cells, which are crucial in connection with Parkinson's disease. "Stem cells offer promising potential for treating Parkinson's disease by transforming into specific nerve cells. However, the precision of this transformation poses a significant challenge with current methods, resulting in low purity," ...

3D eye scans can reveal vital clues about kidney health that could help to track the progression of disease, research suggests. The advance could revolutionise monitoring of kidney disease, which often progresses without symptoms in the early stages. Experts say the technology has potential to support early diagnosis as current screening tests cannot detect the condition until half of the kidney function has been lost. Researchers used highly-magnified images to detect changes to the retina – the layer of tissue at the back of the eye that senses light and sends signals to the ...

Researchers have discovered magnetic monopoles – isolated magnetic charges – in a material closely related to rust, a result that could be used to power greener and faster computing technologies. Researchers led by the University of Cambridge used a technique known as diamond quantum sensing to observe swirling textures and faint magnetic signals on the surface of hematite, a type of iron oxide. The researchers observed that magnetic monopoles in hematite emerge through the collective behaviour of many spins (the angular momentum of a particle). These monopoles glide across the swirling textures on the surface of the hematite, like tiny ...

A new organoid model of the dopaminergic system sheds lights on its intricate functionality and potential implications for Parkinson’s disease. The model, developed by the group of Jürgen Knoblich at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences, replicates the dopaminergic system’s structure, connectivity, and functionality. The study, published on December 5 in Nature Methods, also uncovers the enduring effects of chronic cocaine exposure on the dopaminergic circuit, even after withdrawal.   A completed run, the early morning hit of caffeine, the smell of cookies in the oven - these ...

Recent advances allow imaging of neurons inside freely moving animals. However, to decode circuit activity, these imaged neurons must be computationally identified and tracked. This becomes particularly challenging when the brain itself moves and deforms inside an organism’s flexible body, e.g. in a worm. Until now, the scientific community has lacked the tools to address the problem. Now, a team of scientists from EPFL and Harvard have developed a pioneering AI method to track neurons inside moving and deforming animals. The study, now published ...

The ongoing mental health crisis is causing significant challenges for many psychologists as they grapple with demand fueled by patients presenting with increasingly severe symptoms year after year, according to APA’s 2023 Practitioner Pulse Survey. The survey, which was completed by 561 licensed practicing psychologists between Aug. 30 and Sept. 29, 2023, found that not only did more than half of psychologists (52%) say that they were seeing an increase in severity of symptoms among their patients, but 41% said that they were seeing ...

SYDNEY, Dec. 5, 2023 – Millions suffer from musculoskeletal injuries every year, and the recovery process can often be long and difficult. Patients typically undergo rehabilitation, slowly rebuilding muscle strength as their injuries heal. Medical professionals routinely evaluate a patient’s progress via a series of tasks and exercises. However, because of the dynamic nature of these exercises, obtaining a clear picture of real-time muscle function is extremely challenging. Parag Chitnis of George Mason University led a team that developed a wearable ultrasound system that can produce clinically relevant information about muscle function during dynamic physical activity. He ...

Ashley Dayer hopes to peck away at the notion that bird feeding is simply for the birds. Associate professor in the Department of Fish and Wildlife Conservation at Virginia Tech, Dayer is the lead author of an article published in People and Nature that argues not only for the acknowledgment of the activity’s benefit to humans, but that it should play a role in public guidance and policy. “Wildlife agencies and others making decisions on managing bird feeding need to be considering not only what the science is behind what’s going on with birds, but also the science behind what’s going on with people,” ...

An interdisciplinary research team from the University of Waterloo is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before. Microplastics are commonly found in food and are dangerous pollutants that cause severe environmental damage – finding them is the key to getting rid of them. The research team’s advanced imaging identification system could help wastewater treatment plants and food production industries make informed decisions ...

Unmanned Underwater Vehicles (UUVs) are used around the world to conduct difficult environmental, remote, oceanic, defence and rescue missions in often unpredictable and harsh conditions.  A new study led by Flinders University and French researchers has now used a novel bio-inspired computing artificial intelligence solution to improve the potential of UUVs and other adaptive control systems to operate more reliability in rough seas and other unpredictable conditions.   This innovative approach, using the Biologically-Inspired Experience Replay (BIER) method, has been published by the Institute of Electrical and Electronics Engineers journal IEEE Access.  Unlike conventional ...

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but University of Adelaide researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory. The finding, made by researchers from the School of Agriculture, Food and Wine, widens the concept of aquaporins’ role in plant biology and will have implications for the bioengineering of plants for food production and plant survival. Aquaporins, which belong to a class of membrane ...

Research led by Hiromi Shiraishi, researcher at Chuo University, indicated a steep rise in the importation of American Eel (Anguilla rostrata) live fry to East Asia for aquaculture purposes. This surge poses a potential threat to the already endangered species, further depleting the resources of this species. Japan relies on imports for two-thirds of its eel consumption and it is believed that a significant quantity of American Eel is included in these imports. As a major consumer of eels, Japan is urged to take a leading role in ensuring the sustainable utilisation of eel species, including ...

Superior knee and hip replacements are a step closer after Flinders University and Chinese researchers further test and develop a new orthopedic implant coating which has the strong ability to ward off infection – as well as stimulate bone growth.   The technology, which has been patented after more promising results just detailed in the lead scientific journal Advanced Functional Materials, consists of novel Silver-Gallium (Ag-Ga) nano-amalgamated particles that can be easily applied to medical device surfaces.   “The antibacterial capabilities of compounds derived from silver have been extensively researched. ...
