Volatile air pollutants such as nitrogen dioxide and ozone are only monitored loosely in the EU. Separate devices are used for each individual pollutant, and real-time monitoring is not possible. Birgitta Schultze-Bernhardt from the Institute of Experimental Physics at Graz University of Technology (TU Graz) would like to simplify and significantly improve these measurements. In her MULTI TRACE research project, she is developing a portable device that can determine the concentration of several gaseous pollutants in ambient air with the utmost accuracy ...

Most genes are ancient and shared across species. But a small subset of genes are relative newcomers, spontaneously emerging from stretches of DNA that once encoded nothing at all. Now, after nearly a decade of charting these genes in fruit flies, researchers have discovered how these de novo genes are regulated. In complementary studies, in Nature Ecology & Evolution and PNAS, the team showed how transcription factors and genomic neighbors switch these genes on and integrate them into cellular networks—the first studies to identify these master regulators. Together, the findings shed light on how new genes become ...

KANSAS CITY, MO — July 14, 2025 — While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ears are damaged, the result is often permanent hearing loss, deafness, or balance problems. In contrast, animals like fish, frogs, and chicks regenerate sensory hair cells effortlessly. Now, scientists at the Stowers Institute for Medical Research have identified how two distinct genes guide the regeneration of sensory cells in zebrafish. The discovery improves our understanding of how regeneration works in zebrafish and may guide future studies ...

Astronomers have detected a giant exoplanet – between three and ten times the size of Jupiter – hiding in the swirling disc of gas and dust surrounding a young star. Earlier observations of this star, called MP Mus, suggested that it was all alone without any planets in orbit around it, surrounded by a featureless cloud of gas and dust. However, a second look at MP Mus, using a combination of results from the Atacama Large Millimeter/submillimeter Array (ALMA) and the European Space Agency’s Gaia mission, suggest that the star is not alone after all. The international team of astronomers, led by the University of Cambridge, detected a large gas giant in the star’s ...

Researchers have demonstrated a new technique that allows “self-driving laboratories” to collect at least 10 times more data than previous techniques at record speed. The advance – which is published in Nature Chemical Engineering – dramatically expedites materials discovery research, while slashing costs and environmental impact. Self-driving laboratories are robotic platforms that combine machine learning and automation with chemical and materials sciences to discover materials more quickly. The automated process allows machine-learning algorithms to make use of data from each experiment when predicting which experiment to conduct next to achieve ...

Spotting the Missteps: How MiROM Detects Protein Misfolding in Cancer Cells MiROM identifies proteins by using mid-infrared light to detect molecular vibrations – essentially the natural “dance” of molecules within protein structures. Unlike optical spectroscopy, which measures light attenuation, optoacoustics capture ultrasound waves generated when proteins absorb infrared light. This absorption causes a tiny, localized temperature increase, leading to transient expansion of medium surrounding the protein and the emission of ultrasound waves. By analyzing these signals in real time, MiROM can detect structural changes ...

At the dawn of the millennium, a group of eminent scientists began compiling a list of the threats they felt were most likely to impact the world’s rocky shorelines over the coming quarter of a century. Published in 2002, it included forecasts that – among other things – pollution from oil spills would decrease, the number of invasive species across the world would rise, genetically-modified organisms would have harmful effects on the ocean, and the impacts of global climate change would be felt more intensely. Now, 25 years on, the same academics – along with a larger and more wide-ranging team of international experts – have revisited ...
