“Significant proportion” of world’s rural population missing from global estimates, says study

Aalto University
Peer-Reviewed Publication

Governments, international bodies and researchers rely on global population data for resource allocation and infrastructure planning to disease epidemiology and disaster risk management. In a new study published in Nature Communications, researchers from Aalto University in Finland show the profound and systematic extent to which these datasets underestimate rural population figures worldwide.

Efficient development of drugs with fewer mice

University of Zurich
Peer-Reviewed Publication

New active ingredients such as antibodies are usually tested individually in laboratory animals. Researchers at UZH have now developed a technology that can be used to test around 25 antibodies simultaneously in a single mouse. This should not only speed up the research and development pipeline for new drugs, but also hugely reduce the number of laboratory animals required.

Innovative infant wearable uses artificial intelligence for at-home assessments of early motor development

University of Helsinki
Peer-Reviewed Publication

The smart MAIJU jumpsuit offers a novel approach to at-home monitoring of infants’ early motor development. The wearable device developed collaboratively by the University of Helsinki and the New Children’s Hospital at Helsinki University Hospital combines expertise in medicine, measuring technology and AI, enabling objective and accurate assessment of children’s motor skills without the presence of researchers.

Lords of the molecular rings: An innovative shortcut to high-performance organic materials

University of Vienna
Peer-Reviewed Publication

Scientists at the Institute of Organic Chemistry, University of Vienna, have unveiled an innovative approach for synthesizing azaparacyclophanes (APCs), a class of highly advanced ring-shaped molecular structures with immense potential in material science. Their innovative Catalyst-Transfer Macrocyclization (CTM) method, currently published in JACS Au, streamlines the production of these complex macrocycles, paving the way for more efficient and scalable applications in organic electronics, optoelectronics, and supramolecular chemistry – such as displays, flexible solar cells and transistors.

Researchers develop new nanoplastic for sustainable street lighting

King Abdullah University of Science & Technology (KAUST)
Peer-Reviewed Publication

A new study led by King Abdullah University of Science and Technology (KAUST) Professor Qiaoqiang Gan and in collaboration with King Abdulaziz City for Science and Technology (KACST) shows how nanomaterials can significantly reduce the carbon emissions of LED (light emitting diode) streetlights. Gan and his colleagues estimate that by adopting this technology, the United States alone can reduce carbon dioxide emissions by more than one million metric tons.

Engraving light nonlinearly: A breakthrough in optical storage promises a faster, greener future

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

A groundbreaking study from Northeast Normal University, published in Light: Science & Applications, introduces "Upconversion Charging" (UCC), a revolutionary optical storage technique. Using low-energy photons, UCC slashes data writing times to 0.01 seconds, enabling fast, high-resolution, eco-friendly storage with phosphors like Gd₃Ga₅O₁₂:Cr³⁺. This innovation promises transformative applications, from compact data libraries to advanced medical imaging, redefining the future of sustainable, high-capacity technology.
