Scientists build a healthy dietary pattern using ultra-processed foods
Scientists demonstrate it is possible to build a healthy diet with 91 percent of the calories coming from ultra-processed foods (as classified using the NOVA scale) while still following the recommendations from the 2020-2025 Dietary Guidelines for Ame…
Low-glucose sensor in the brain promotes blood glucose balance
Does the brain play a role in blood glucose regulation? Researchers at Baylor College of Medicine found evidence in animal models that glucose-sensing neurons in the brain are important for whole body glucose regulation, including during diabetes.
Exposure to neurotoxic rodenticide bromethalin in birds of prey
In 2020, Tufts Wildlife Clinic Director Maureen Murray, V03, published a study that showed 100% of red-tailed hawks tested at the clinic were positive for exposure to anticoagulant rodenticides (ARs). Such exposure occurs when these chemicals are used …
Warmer weather makes venomous snake bites more likely, especially in spring
Climate change is not only making Georgia hotter but also increasing the likelihood of snake bite, according to a new study. Every degree Celsius of daily temperature increase corresponds with about a 6% increase in snake bites, researchers found.
Researcher turns one of the basic rules of construction upside down
Structural engineers are familiar with seventeenth-century scientist Robert Hooke’s theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regard…
Satellite security lags decades behind the state of the art
Researchers have tested the software of three satellites. And they found many standard security mechanisms missing.
World’s largest association of computing professionals issues Principles for Generative AI Technologies
In response to major advances in Generative AI technologies — as well as the significant questions these technologies pose in areas including intellectual property, the future of work, and even human safety — the Association for Computing Machinery’s…
Crawford Lake, Canada, chosen as the primary marker to identify the start of the Anthropocene epoch
An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global Boundary …
Size does matter: Group size and mating preferences drive deeper male voices
Group size and mating preferences may have caused male primates, including humans, to evolve deeper voices than females. The findingsĀ can help to shed light on social behavior in humans and their closest living relatives.
Using AI to save species from extinction cascades
Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most …
Drug precursor biosynthesis hinges on carrier-mediated ring formation
The entire biosynthetic pathway of actinopyridazone has been unveiled, revealing that an unprecedented carrier protein-mediated ring-forming step is key to its synthesis.
Widespread illegal trade of hazardous chemicals
Researchers have studied the global trade in highly hazardous chemicals subject to a global treaty — the Rotterdam Convention. The results are sobering: Nearly half of the total trade volume of these chemicals crosses national borders illegally, calli…
Capturing the immense potential of microscopic DNA for data storage
A ‘biological camera’ bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data. This represents a significant breakthrough in encoding and storing images directly…
Immune memory is achieved by epigenetic and topological rearrangements of DNA in immune cells
A team of researchers has discovered that the memory of the immune system relies on characteristic epigenetic features and a specific 3D arrangement of the DNA in the nucleus of memory cells, allowing for a fast activation of these cells. These feature…
Revolutionary self-sensing electric artificial muscles
Researchers have made groundbreaking advancements in bionics with the development of a new electric variable-stiffness artificial muscle. This innovative technology possesses self-sensing capabilities and has the potential to revolutionize soft robotic…
New target for antibiotics promises treatment for multi-drug resistant superbugs
The World Health Organization lists bacteria that are resistant to antibiotics as one of the top 10 global health threats. Therefore, researchers are looking for new antibiotics to counter this resistance. Biophysicist have now discovered that the rela…
Lower levels of physical activity can protect against depression among older adults
Brand new research has revealed that even moderate daily physical activity can reduce the risk of depression.
