Neutrophils are less aggressive at night, explaining why nighttime heart attacks cause less damage than daytime events

A study by CNIC reveals that neutrophils, a type of immune cell, are less aggressive at night, resulting in less severe heart attacks. Researchers developed a pharmacological strategy to block the molecular clock in neutrophils, reducing their harmful potential during infarction.

Reproduced human neural circuits show the crucial role of the thalamus in shaping the cortical circuit

Scientists have successfully replicated human neural circuits using assembloids, a type of miniature organoid derived from induced pluripotent stem cells. The study shows that the thalamus plays a crucial role in shaping cell-type specific neural circuits in the human cerebral cortex, promoting cortical growth and maturation.

Chromatin accessibility maps reveal how stem cells drive myelodysplastic progression

Chromatin accessibility maps reveal that MDS stem cells gradually lose their normal identity and acquire characteristics typical of myeloid progenitors. A 'progenitor score' developed by the team tracks cell movement toward a progenitor-like state, correlating with disease severity and prognosis.

Global measures consistently underestimate food insecurity; one in five who suffer from hunger may go uncounted

A new study reveals that global food insecurity analyses systematically underestimate hunger, with significant implications for humanitarian aid allocation. The researchers found that 66.2 million people, or one in five, who suffer from hunger may go uncounted due to underestimation.

Largest study of its kind highlights benefits – and risks – of plant-based diets in children

A large meta-analysis of over 48,000 children found that well-planned plant-based diets can support healthy growth and even offer additional health benefits for children. However, the study also highlights risks of deficiencies in key nutrients such as vitamin B12 and zinc if not obtained through fortified foods or supplements.

Chinese scientists reveal how isoflavone 6-hydroxylase mediates soybean resistance to Phytophthora sojae

Researchers discovered the biosynthetic pathway of glycitein, a key soybean isoflavonoid, and its role in plant immunity. They found that GmIF6H1 enzyme catalyzes the production of glycitein, which acts synergistically with glyceollins to defend soybeans against infection by Phytophthora sojae.

Atomic Josephson junctions: How Bose-Einstein condensates replicate Shapiro steps

Researchers simulated the Josephson effect using ultracold atomic gases and observed characteristic Shapiro steps, confirming its universality. The findings enable the study of quantum effects in atomic systems, paving the way for 'atomtronics' and potential applications in quantum computing and medical diagnostics.

Risk to Amazon rainforest from land use and climate change

A new study estimates that the Amazon rainforest could lose up to 38% of its area by the end of the 21st century due to land use changes and climate change. The research, published in PNAS, suggests that abrupt transitions from dense forest coverage to savannah-like landscapes pose a significant risk to the ecosystem.

Wildfires can turn harmless minerals in soils into contaminants

Researchers found that wildfires can convert chromium 3, a benign form in rocks and soil, into the carcinogenic chromium 6. Soils from summits contained high levels of chromium 6 when burned at temperatures above 750 F, which could taint groundwater for up to 2.5 years. The study highlights the need for better understanding of fire's i...

UBCO study finds microdosing can temporarily improve mood, creativity

A UBC Okanagan study found that microdosing psychedelics temporarily improves mood, creativity, and wellbeing, but these effects do not persist on non-dosing days. The study, tracking over 1,435 participants from 49 countries, suggests that microdosing may 'reactivate' or build upon prior effects of larger-dose psychedelic experiences.
