The automotive industry is undergoing a transformative shift toward sustainable propulsion systems to meet stringent environmental regulations, such as the European Union’s push for near-zero-emission vehicles. Among the promising alternatives, proton exchange membrane fuel cells (PEMFCs) stand out due to their high efficiency and rapid response times. However, optimizing PEMFC performance requires advanced turbocharging systems to supply compressed air to the fuel cell stack. Centrifugal compressors, a key component in ...

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 ...

Molecules like DNA are capable of storing large amounts of data without requiring an energy source, but accessing this molecular data is expensive and time consuming. Publishing May 16 in the Cell Press journal Chem, researchers have developed an alternative method to encode information in synthetic molecules, which they used to encode and then decode an 11-character password to unlock a computer.   “Molecules can store information for very long periods without needing power. Nature has given us the proof of principle that this works,” says corresponding author and ...

For the first time, researchers from King’s College London, Imperial College London and The Alan Turing Institute, have created over 3,800 anatomically accurate digital hearts to investigate how age, sex and lifestyle factors influence heart disease and electrical function. Creating cardiac ‘digital twins’ at this scale has helped scientists discover that age and obesity cause changes in the heart’s electrical properties, which could explain why these factors are linked to a higher risk of heart disease. The results, published today in Nature Cardiovascular Research, show the opportunities that cardiac digital twins at scale ...

While Alzheimer’s disease is mostly considered a disorder of the brain, emerging evidence suggests that the condition also affects other organs of the body.

With the rapid development of digital technology and diversification of consumer needs, companies have adopted the buy-online-and-assemble-in-store (i.e., BOAS) approach to better meet the individual needs of consumers. Through BOAS, consumers can place orders online, pick up the products and enjoy services such as assembly at a physical shop. However, due to uncertain post-processing costs, it remains unclear whether companies would benefit from the use of BOAS. Furthermore, the impacts of BOAS on consumers and the environment are of research interest. In a ...

On March 28, 2025, a catastrophic earthquake of magnitude 7.7 struck central Myanmar, marking the most devastating seismic event in the region since 1912. Originating along the Sagaing Fault — a 1,400-km-long dextral strike-slip boundary separating the Burma Microplate and Sunda Plate — the earthquake propagated a supershear rupture over 460 km with surface displacements exceeding 6 meters. The shallow (10 km depth) strike-slip mechanism unleashed violent shaking (Modified Mercalli Intensity IX) across densely populated urban centers, including Mandalay, Sagaing and Naypyidaw, while amplifying seismic energy in distant locations such as Bangkok, Thailand. The human toll was ...

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 ...

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 ...

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 ...

A University of Queensland study has shown scientific knowledge on the conservation of endangered species is often overlooked when not presented in English. PhD candidate Kelsey Hannah examined articles about the protection and management of birds, mammals, and amphibians and compared how often those in English and 16 other languages were cited in further work. “The 500 papers in my study were published in peer-reviewed journals and available internationally to people working in conservation,” Ms Hannah said. “Across the board, the non-English language papers had significantly fewer citations. “The English-language articles had a median of 37 citations while the ...

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 ...

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 ...
