As we move through the world, our brains do more than plan our actions - they anticipate potential disruptions. A new Western study published in the high impact journal Nature reveals that we rely on sensory expectations to get prepared for unexpected disturbances, helping us react faster and more accurately.

Researchers have developed a method to calibrate electron spectrometers with extreme accuracy by linking microwave, optical, and free-electron frequencies. Frequency is one of the most precisely measurable quantities in science. Thanks to optical frequency combs, tools that generate a series of equally spaced, precise frequencies like the teeth of a ruler, researchers can connect frequencies across the electromagnetic spectrum, from microwaves to optical light, enabling breakthroughs in timekeeping, spectroscopy, and navigation .

New analysis of chemical signatures measured by NASA's Curiosity Rover gives a peek at Mars' past to a time, some 3.7 billion years ago, when it was warmer and wetter. Through measurements of isotopic ratios of oxygen, a team of collaborators, including researchers from Caltech's campus and NASA's Jet Propulsion Laboratory (JPL) have discovered that the lake which once existed in Mars' Gale Crater was undergoing significant evaporation earlier than the mineralogy and geochemistry of the lake bed sediments would suggest.

Researchers at the Cluster of Excellence "Balance of the Microverse" at the University of Jena have discovered a previously unknown survival mechanism in bacteria. They found that the freshwater bacterium Caulobacter crescentus can change its nutritional strategy in a matter of seconds with the help of a special 'RNA sponge'.

Sleep problems affect more than one in five residents in long-term care facilities, with pain, daytime napping and certain medications emerging as key contributors. An international team led by University of Waterloo researchers analyzed health records from more than 21,000 residents aged 65 and older living in 228 long-term care homes across New Brunswick and Saskatchewan between 2016 and 2021, using data from the standardized interRAI assessment system.

An international collaboration between the University of Valencia and Texas A&M University-Corpus Christi has achieved an important advance in the study of seasonal and multi-annual sea level changes. By applying artificial intelligence (AI) techniques, the teams have significantly extended the forecasting timescales of these variations, strengthening coastal planning capabilities and scientific cooperation in ocean research.

Researchers at Universities of Göttingen and Kassel analyse models of multifunctional land use Land use is at the heart of the many emergencies facing our world today: climate change, biodiversity loss, social injustice and food insecurity. These - exacerbated by unsustainable practices such as industrial agriculture - combine to create simultaneous and interconnected crises.

Researchers at the University Hospital Bonn and the University of Bonn are reconstructing neural networks in the laboratory and investigating new mechanisms of signal transmission in the brain How do the circuits of the human brain work - and what happens when they are disrupted? To investigate these questions, researchers at the Eye Clinic of the University Hospital Bonn (UKB) and the University of Bonn, together with colleagues from the Univer

A puzzle in theoretical chemistry has been solved at TU Wien: a new computational method now makes it possible to calculate the forces between large molecules with unprecedented accuracy. Why can geckos walk up walls? Why does nitrogen become liquid at -196 °C? Many everyday phenomena can be explained by van der Waals forces - weak bonds between molecules that are notoriously difficult to calculate.

4D visualisation of the vascularisation of an entire kidney obtained using the multi-lens probe developed in this study. Veins are shown in blue and arteries in red. Colour variations indicate blood flow velocity: the brighter the colour, the faster the blood is flowing. The smallest vessels are less than 100 micrometres in diameter.

A pair of distant black hole mergers, measured just one month apart in late 2024, are improving how scientists understand the nature and evolution of the most violent deep-space collisions in our universe. The new observations suggest that the colliding black holes might themselves have been products of earlier cosmic smashups.

An international clinical study led by the Medical University of Vienna shows that the drug patritumab deruxtecan (HER3-DXd) can have a promising effect in patients with active brain metastases of various tumour types. Patients with advanced disease benefited from treatment in both non-small cell lung cancer (NSCLC) and metastatic breast cancer, as shown in two simultaneous publications in The Lancet Oncology.

Scientists at TU Delft have developed a new algorithm that allows multiple autonomous drones to work together to control and transport heavy payloads, even in windy conditions.

Researchers find those who began using cannabis regularly before age 15 were more likely to seek care for depression, anxiety, suicidal thoughts and physical health problems as young adults Adolescents who start using cannabis early and often are more likely to need health care for both mental and physical problems as they enter adulthood, according to a new study led by McGill researchers.

Two gravitational wave signals explain why the heavier black holes of the causal pairs did not originate in a stellar explosion Unusual signals: Two extraordinary gravitational wave events, which can also be traced back to two pairs of merging black holes, stand out from the data jointly observed by the LIGO, Virgo, and KAGRA detectors in the fall of 2024.

Researchers have developed and tested Votegral a complete e-voting pipeline, demonstrating for the first time that there is a plausible and practical approach to coercion-resistant electronic voting in elections. Over the past decade, many studies have identified coercion and corruption as major challenges for electoral integrity around the world.

Drugs to treat inflammatory and autoimmune diseases - such as asthma, psoriasis, rheumatoid arthritis or Chrousos syndrome - act mainly through the glucocorticoid receptor (GR). This essential protein regulates vital processes in various tissues, so understanding its structure and function at the molecular level is essential for designing more effective and safer drugs.

Scientists at the University of Glasgow have harnessed a powerful supercomputer, normally used by astronomers and physicists to study the universe, to develop a new machine learning model which can help translate the language of proteins. In a new study, published in Nature Communications, the cross-disciplinary team developed a large language model (LLM), called PLM-Interact, to better understand protein interactions, and even predict which mutations will impact how these crucial molecules 'talk' to one another.

Is your ultra-high-definition television really worth it? Do you need a 4K or an 8K screen to get the best viewing experience at home? According to researchers at the University of Cambridge and Meta Reality Labs, the human eye has a resolution limit: in other words, there are only so many pixels the eye can see.

In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for suitable atomic nucleus states had been ongoing worldwide.
