A Macquarie University team proposes using genetically engineered black soldier flies (Hermetia illucens) to address worldwide pollution challenges and produce valuable raw materials for industry, including the USD $500 billion global animal feed market.  In a new paper published on 24 July in the journal Communications Biology, scientists at Macquarie University outline a future where engineered flies could transform waste management and sustainable biomanufacturing, addressing multiple United Nations Sustainable Development Goals (SDGs).  Synthetic biologist Dr Kate Tepper is lead author of the paper and a Postdoctoral Research Fellow at Applied BioSciences, Macquarie University. “One ...

OAK BROOK, Ill. – A new study of more than 10,000 non-smoking adults found that solid lung nodules were present in a considerable portion of study participants. Non-smokers are traditionally thought to be at low risk for lung nodules and lung cancer. The results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA). Incidental lung nodules are common findings on chest CT and in high-risk groups are more likely to be a sign of early-stage lung cancer. Because most previous research on the prevalence and size of lung nodules has typically been ...

(COLUMBUS, Ohio) – As the nation’s youth mental health crisis continues, providers continue to find ways to help address gaps in care. Patients who receive care for suicidal thoughts and behaviors need extra support as they transition after they are discharged from inpatient care or the emergency department. Caring Contacts are validating messages sent to patients via text messages, postcards or letters to offer patients ongoing care and support without placing any demands (such as reminders to attend their next appointment). At Nationwide ...

CORVALLIS, Ore. – Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, new research has shown. “There is a growing conservation movement regarding coastal areas that host surf breaks,” said Jacob Bukoski of Oregon State University, one of the study’s co-authors. “Earlier research showed that surf breaks tend to be biodiversity hotspots, but no one had looked at the stocks of carbon held within these ecosystems – carbon that could drive climate change if ...

A new discovery by a team of paleontologists, led by Dr. Mathieu Boisville (University of Tsukuba, Japan), has uncovered a new species of the extinct genus Ontocetus from the Lower Pleistocene deposits in the North Atlantic. This species, named Ontocetus posti, displays surprising similarities in feeding adaptations to the modern walrus (Odobenus rosmarus), highlighting an intriguing case of convergent evolution. The research is published in the open access journal PeerJ Life & Environment. The fossils ...

Involving women in implementing solar energy technologies in developing countries not only has great climate impact. A new study published in Nature Energy and carried out by researchers from Chalmers University of Technology, Sweden, shows that empowering women through energy care work can change unjust, gendered norms and long-lived injustices. Unlike going from fossil to renewable fuels within the transport sector, transitioning to renewable energy for electricity production is often done at the local level due to decentralised energy providers. Around the world, there are community-led programmes that provide solar, wind and hydro power, as alternative, greener energy sources. ...

PULLMAN, Wash. – The smaller carbon footprint, or wheel print, of automatic delivery robots can encourage consumers to use them when ordering food, according to a Washington State University study. The suitcase-sized, self-driving electric vehicles are much greener than many traditional food delivery methods because they have low, or even zero, carbon emissions. In this study, participants who had more environmental awareness and knowledge about carbon emissions were more likely to choose the robots as ...

ROCHESTER, Minn. — Cardiologists in Mayo Clinic's Heart Rhythm Clinic are using a new innovative energy source to safely and successfully treat a common type of heart arrhythmia. The therapy, called pulsed field ablation (PFA), has received Food and Drug Administration (FDA) approval and represents a significant milestone in treating atrial fibrillation (AFib). The irregular and often very rapid heart rhythm of AFib can lead to blood clots in the heart, increasing a patient's risk of stroke. Clinicians can use medication and therapies to help reset the heart rhythm, but some patients have AFib that ...

Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets, a new study reveals.   Researchers believe that a currently over-consuming 56.9% of the global population would save 32.4% of global dietary emissions by changing their diet to the planetary health diet proposed by the EAT-Lancet Commission.  Publishing their findings today (13 Aug) in Nature Climate Change, an international group of researchers note that a diet switch to the planetary health diet would balance the ...

Key points: Researchers identified a significant link between heme iron—iron found in red meat and other animal products —and risk of type 2 diabetes (T2D), as well as the metabolic pathways underlying the link. Non-heme iron—iron found in plant-based foods—was not associated with risk of T2D. The study suggests that cutting down on heme iron from red meat and adopting a plant-rich diet can help lower diabetes risk. And it raises concerns about the addition of heme to increasingly popular plant-based meat alternatives. Boston, MA—Higher intake ...

TORONTO, ON – Do older adults who live alone feel less satisfied with their lives? A new analysis of about 12,000 respondents aged 65 and older reveals that what matters for Canadian older adults’ life satisfaction is not living alone per se. Rather personality-based social dispositions play a key role in how older adults feel about living alone. In addition, the role these dispositions play tend to differ between Canadian-born and immigrant older adults. The researchers found that despite the existence ...

A computer algorithm has achieved a 98% accuracy in predicting different diseases by analysing the colour of the human tongue. The proposed imaging system developed by Iraqi and Australian researchers can diagnose diabetes, stroke, anaemia, asthma, liver and gallbladder conditions, COVID-19, and a range of vascular and gastrointestinal issues. Engineering researchers from Middle Technical University (MTU) and the University of South Australia (UniSA) achieved the breakthrough in a series of experiments where they used 5260 images to train machine learning algorithms to detect tongue colour. Two ...

Bisphenols are widely used as the main raw material for plastics such as receipts, water bottles, water containers, and vinyl due to their heat-resistant and mechanochemical properties. Among bisphenols, bisphenol A (BPA) that we often refer to as an "endocrine-disrupting chemicals" has been linked to adverse effects on reproduction, development, intelligence, and various metabolic diseases. Bisphenol F (BPF), a recently developed alternative to BPA Bisphenol A has also been reported in the literature to cause neurological disruption and various health risks. Dr. Jong Min Kim of the Materials Architecturing ...

Cell–cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion, Hokkaido University researchers find. Fingerprints are one of the best-recognised examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors affecting this pattern formation have been reported, the exact mechanisms underlying the process are still not fully understood. A team of researchers, led by Associate ...

RICHLAND, Wash.—Last year marked Earth’s warmest year on record. A new study finds that some of 2023’s record warmth, nearly 20 percent, likely came as a result of reduced sulfur emissions from the shipping industry. Much of this warming concentrated over the northern hemisphere. The work, led by scientists at the Department of Energy’s Pacific Northwest National Laboratory, published today in the journal Geophysical Research Letters. Regulations put into effect in 2020 by the International Maritime Organization required a roughly 80 percent reduction in the sulfur content of shipping ...

HOUSTON – (Aug. 12, 2024) – Ammonia plays a critical role in sustaining food production for the world’s growing population, but making it accounts for about 2% of global energy consumption and 1.4% of carbon dioxide emissions. Rice University engineers have developed a revolutionary reactor design that could decarbonize ammonia production while also mitigating water pollution. In a study published in Nature Catalysis, a team of Rice engineers led by Haotian Wang described the development of a new reactor system that converts nitrates — common pollutants found in industrial wastewater and ...

New research from a Florida State University professor and colleagues explains the mathematics behind how initial predispositions and additional information affect decision making. The research team’s findings show that when decision makers quickly come to a conclusion, the decision is more influenced by their initial bias, or a tendency to err on the side of one of the choices presented. If decision makers wait to gather more information, the slower decision will be less biased. The work was published today in Physical Review E. “The basic result might ...

A new study found that most routine laboratory tests are not reliable for diagnosing Long COVID, also known as Post-Acute Sequelae of SARS-CoV-2 infection (PASC). The study, published today in Annals of Internal Medicine, found no reliable biomarker among 25 routine clinical laboratory values for prior infection, PASC or specific types of PASC clusters. This suggests none of these routine labs can serve as a clinically useful biomarker of PASC. "Our study shows patients can have severe Long COVID with normal lab results. This ...

Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys’ base. Now, a team of UCLA engineers has created a new class of tunable dynamic material that mimics the inner workings of push puppets, with applications for soft robotics, reconfigurable architectures and space engineering. Inside a push puppet, there are connecting cords that, when pulled taught, will make the toy stand stiff. But by loosening these cords, the “limbs” of the toy will go limp. Using the same cord tension-based principle that controls a puppet, researchers have developed a new type of metamaterial, a material ...

From a nondescript industrial building in the small town of Crossville, Tennessee, the team of engineers at Whisper Aero is planning a revolution in aviation technology. Previously home to a publisher of magazines — including, coincidentally, Trade-A-Plane, an airplane sales publication started in 1937 — the long-empty property’s cavernous spaces are now filled with multidisciplinary activities that include the creation of a new electric aircraft engine. In January 2024, employees of the 3-year-old start-up moved into their new headquarters, refurbishing its dusty rooms into a 21st century aerospace technology facility with areas ...

PROVIDENCE, R.I. [Brown University] — A new study that explores ancient temperatures and rainfall patterns in the tropical Andes of South America has revealed how 16,000 years of climate history in this part of the world was driven by carbon dioxide levels and ocean currents from global climate events. Led by Brown University researchers, the study marks the first high-resolution temperature record covering the past 16,000 years in the tropical Andes and could help scientists predict and mitigate future climate impacts in tropical regions of the planet. The work is described in the Proceedings of the National Academy of Science. “Usually ...
