Can localized fertilization become a key strategy for green agricultural development?

2025-05-16
In agricultural ecosystems, there exists a remarkable heterogeneity in the spatial and temporal distribution of soil nutrients. This heterogeneity can cause the nutrient concentrations that different roots of the same plant are exposed to vary by several orders of magnitude, which undoubtedly poses a great challenge to plant growth. In the face of such a complex soil environment, plants have gradually developed a series of coping strategies during the long evolutionary process. Their roots can keenly sense the nutrient-rich hotspots and make corresponding responses. However, traditional fertilization methods are difficult to precisely meet the needs of plants. They not ...

How do middle-aged folks get dementia? It could be these proteins

2025-05-16
Dementia usually affects older people, so when it occurs in middle age, it can be hard to recognize. The most common form is frontotemporal dementia (FTD), which is often mistaken for depression, schizophrenia, or Parkinson’s disease before the correct diagnosis is reached.  Now, as part of an NIH-funded study, researchers at UC San Francisco have found some clues about how FTD develops that could lead to new diagnostics and get more patients into clinical trials. The findings appear in Nature ...

Novel molecular maneuver helps malaria parasite dodge the immune system

2025-05-16
Researchers at Weill Cornell Medicine have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body’s immune system, sometimes for years. It turns out that the parasite, Plasmodium falciparum, can shut down a key set of genes, rendering itself “immunologically invisible.” “This finding provides another piece of the puzzle as to why malaria has been so difficult to eradicate,” said Dr. Francesca Florini, research associate in microbiology and immunology ...

A step closer to the confident production of blood stem cells for regenerative medicine

2025-05-16
Stem cells can produce any other cell type, it is just a matter of telling them in the right way. From a biological perspective, this means activating the proper genetic programme by pressing the right keys, this is, the right genes, at the right moment. Quite often, blood cancer patients require the replacement of their blood stem cells in the bone marrow, the tissue producing blood cells where their cancer grows. Unfortunately, finding a compatible donor happens to be too challenging sometimes. What if we could produce the cells that make blood in the lab, right from basic stem cells, and use them to regenerate a new and healthy ...

School dinners may encourage picky teenagers to eat better, says new study

2025-05-16
Having school dinners rather than packed lunches could encourage picky eating 13-year-olds to eat a wider variety of foods, according to a new University of Bristol-led study.  The findings are published in the Journal of Human Nutrition and Dietetics today [15 May]. The research showed when children who were picky eaters as preschoolers got to choose their own food (school dinners) at lunchtime, they were less picky in what they ate, compared with a packed lunch. To the research team’s knowledge, this is the first time that lunchtime food behaviours in picky children have been studied outside of the home, and ...

Study suggests loss of lung capacity begins between the ages of 20 and 25

2025-05-15
A study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by ”la Caixa” Foundation, in collaboration with the Clínic-IDIBAPS, has shown for the first time, how lung capacity evolves from childhood to old age. The findings, published in The Lancet Respiratory Medicine, provide a new basic framework for assessing lung health. Until now, it was thought that lung function increased until it peaked at around 20–25 years of age, after which it stabilised. It was also thought that in later adulthood, lung function begins to decline as the ...
