Study reveals optimum time to apply eco-friendly biopesticides to tackle Oriental migratory locust pest

Researchers from the Chinese MARA-CABI Joint Laboratory have discovered the optimum time to apply safer-to-use biopesticides to fight the Oriental migratory locust pest. The study, published in Frontiers in Physiology, found that applying biopesticides on younger locusts at dawn or dusk is most effective due to lower body temperatures.

Do forest trees really “talk” through underground fungi?

Researchers found no strong evidence that underground fungal networks, known as common mycorrhizal networks (CMNs), offer benefits to trees and their seedlings. While CMNs exist, there is limited understanding of their structure and function in the field, leading to questionable claims about resource transfer and seedling survival.

Black girls benefit most when STEM teachers train up

A study by Rice University found that students in classes taught by STEM teachers who received professional development training were more likely to pursue STEM majors in college. Black female students showed the greatest increase, with nearly double the percentage of non-AMP! teachers.

Nightly sleep is key to student success

A recent study at Carnegie Mellon University discovered that students who receive less than six hours of sleep per night experience a pronounced decline in academic performance. The study, which tracked over 600 first-year college students, found that each hour of lost sleep corresponded to a 0.07 decrease in end-of-term GPA.

The carbon intensive shipping activities on the high seas could become a potential barrier against the worldwide carbon mitigation and sustainability efforts

A recent study found that high seas shipping accounts for one-third of all shipping emissions, with annual CO2-e emissions reaching 211.60 million metric tonnes in 2019. The study suggests implementing tailored carbon mitigation policies in different high seas regions could reduce emissions by up to 54.36 million tonnes.

Study suggests fructose could drive Alzheimer’s disease

A study suggests that fructose metabolism in the brain may be driving the development of Alzheimer's disease, an evolutionary survival pathway gone awry. Researchers found that fructose reduces blood flow to areas involved in self-control and memory, leading to progressive brain atrophy and neuron loss.

Out with the old, in with the new? Exploring differences in elite mobility during the Meiji Restoration

A new study by Tokyo University of Science researchers examines the connection between political regime changes and social mobility during the Meiji Restoration. The results show that social mobility increased before the consolidation of a new political power, with meritocracy playing a key role in this period.

Overweight and obesity prevalent and poorly managed among adults with type 1 diabetes

A recent study found that adults with type 1 diabetes are at a high risk of being overweight or obese, but only half receive lifestyle recommendations to manage their weight. The study also highlighted the importance of individualized patient education in improving weight management for these patients.

Urban birds prefer native trees

A long-term study from Lund University in Sweden found that native trees are preferred by urban birds due to their availability of resources. Non-native trees lack an evolutionary history with the local ecosystem and have fewer insects, leading to a shortage of food for insectivorous birds.

Scientific AI’s ‘black box’ is no match for 200-year-old method

A new study uses Fourier analysis to understand how deep neural networks learn complex physics. By analyzing the equation of a fully trained model, researchers were able to identify crucial information about how the network learns and generalizes. This breakthrough could accelerate the use of scientific deep learning in climate science.

The relationship between ghosting and closure

A recent study found nearly two-thirds of participants have ghosted someone, and individuals with a high need for closure reported even lower needs satisfaction after being ghosted. On the other hand, those who wanted closure felt more positive when recalled times they were acknowledged by their partner.

Reign of invasive rusty crayfish may be ending; Wisconsin lakes rejoice

A new study suggests that the invasive rusty crayfish may be dying off naturally, allowing native water plants and snails to flourish. In some Northern Wisconsin lakes, crayfish populations have declined by nearly zero, leading to a resurgence of plant life and potential ecosystem recovery.

Dispersed marketing responsibility enhances the profitability of firms in the early stages of their operations

A recent study found that dispersing marketing responsibility between personnel groups in early-stage operations promotes market orientation and improves profitability. Young firms should avoid rigid structures, instead focusing on information flow to support marketing in the early stages.

How teamwork makes superbugs more deadly and drug-resistant

Researchers have characterised the mutually beneficial relationship between Klebsiella pneumoniae and Acinetobacter baumannii, two pathogens responsible for severe infections. This relationship enables Klebsiella to survive in higher antibiotic concentrations, making it more deadly and resistant to treatment.
