Ukraine filed lawsuits against Poland, Hungary, and Slovakia over a ban on imports of its agricultural products, Economy Minister Yuliia Svyrydenko said in a statement Monday. “It is crucially important for us to prove that individual member states cannot ban imports of Ukrainian goods. That is why we are filing…
A new study finds that creating physical gaps in the forest canopy give eastern hemlocks more access to resources and help those trees withstand infestation by an invasive insect. The approach adds another tool to the toolkit that foresters can use to protect these trees. Eastern hemlocks are an ecologically…
When it comes to weight loss, nuts can get a bad rap — while they’re high in protein, they’re also high in fats, and this often deters those looking to shed a few kilos. But new research from the University of South Australia shows that you can eat almonds and…
An innovative phase 2 clinical trial led by Dana-Farber Cancer Institute in collaboration with 10 major brain tumor centers around the country and designed to find new potential treatments for glioblastoma has reported initial results in the Journal of Clinical Oncology. While none of the three therapeutics tested so far…
There has been a real race among scientists to create a technology that enables easy protein sequencing. Professor of Chemical Biology Giovanni Maglia of the University of Groningen has now found the missing piece in the puzzle: a way to transport a protein through a nanopore, which allows sequencing of…
Remote workers can have a 54% lower carbon footprint compared with onsite workers, according to a new study by Cornell University and Microsoft, with lifestyle choices and work arrangements playing an essential role in determining the environmental benefits of remote and hybrid work. The study, published in the Proceedings of…
In recent years, cancer researchers have hailed the arrival of chimeric antigen receptor T cell (CAR T) therapy, which has delivered promising results, transforming the fight against various forms of cancer. The process involves modifying patients’ T-cells to target cancer cells, resulting in remarkable success rates for previously intractable forms…
Zachary Schug, Ph.D., assistant professor in the Molecular and Cellular Oncogenesis Program of the Ellen and Ronald Caplan Cancer Center at The Wistar Institute, has published a new paper in the journal Nature Cancer. Schug’s paper — titled, “Acetate acts as a metabolic immunomodulator by bolstering T-cell effector function and…
A new study looks at the impact of learning environments on the academic success of racialized students. Compared to their peers, these students feel they have less control in their academic environment, less confidence and self-efficacy in their academic abilities, and weaker connections to other students and professors. The University…
Climate change is causing extinctions at an increasing rate, a new study by the University of Arizona researchers shows. They surveyed populations of the Yarrow’s spiny lizard in 18 mountain ranges in southeastern Arizona and analyzed the rate of climate-related extinction over time. “The magnitude of extinction we found over…
Although there are some cultural exceptions to the rule, medicines for children are often given in liquid form that is sweetened to make it taste good. But not every child experiences the same medicine in the same way. A multidisciplinary research group specializing in pediatrics, genetics, and psychophysics, co-led by…
As the days get shorter and chillier in the northern hemisphere, those who choose to work out in the mornings might find it harder to get up and running. A new study in PNAS identifies a protein that, when missing, makes exercising in the cold that much harder — that…
Living things act with purpose. But where does purpose come from? How do humans make sense of their relation to the world and realize their ability to effect change? These fundamental questions of agency — acting with purpose — have perplexed some of the greatest minds in history including Sir…
Some 2,000 years ago in ancient Rome, glass vessels carrying wine or water, or perhaps an exotic perfumes, tumble from a table in a marketplace, and shatter to pieces on the street. As centuries passed, the fragments were covered by layers of dust and soil and exposed to a continuous…
Neurons are talkers. They each communicate with fellow neurons, muscles or other cells by releasing neurotransmitter chemicals at “synapse” junctions, ultimately producing functions ranging from emotions to motions. But even neurons of the exact same type can vary in their conversational style. A new study in Cell Reports by neurobiologists…
Adding more natural areas across our towns and cities could cool them by up to 6°C during heatwaves, according to new research from the University of Surrey’s Global Centre for Clean Air Research (GCARE).
