Babies as young as two months old are able to categorise distinct objects in their brains – much earlier than previously thought – according to new research from neuroscientists in Trinity College Dublin.  The research, which combined brain imaging with artificial intelligence models, enriches our understanding of what babies are thinking and how they learn in the earliest months of life. The study has been just published in the journal Nature Neuroscience by a team from Trinity College Institute of Neuroscience (TCIN) and the ...

Tsukuba, Japan—The underwater dolphin kick is a swimming technique in which propulsion is generated solely through the undulatory motion of the lower limbs, increasing swimmers' speed by moving the body in a wavelike pattern similar to fish or marine mammals. However, because the human body is not naturally adapted to such undulatory movements, swimmers must master advanced motor skills to improve performance in this technique. This study analyzed time-series data of joint movements during underwater dolphin kick to examine differences in swimmer performance levels. Using conducting kinematic synergy analysis, the researchers identified two ...

Polaritons—hybrid light-matter particles—allow light to be squeezed into deep subwavelength scales, holding great promise for ultra-compact photonic devices. By structuring materials into periodic crystals, known as polaritonic crystals (PoCs), researchers can engineer exotic optical modes called Bloch modes for enhanced light control. However, once fabricated, these crystals and their Bloch modes are fixed, lacking the dynamic tunability required for adaptive optical devices. While graphene supports highly tunable plasmon polaritons, their performance is limited by substantial optical ...

Wetlands make up only about six percent of the land area but contain about 30 percent of the terrestrial organic carbon pool. Therefore, CO2 emissions from wetlands are central to the global climate balance. In Denmark, the plan is to flood 140,000 hectares of low-lying land such as bogs and meadows as part of the Green Tripartite Agreement. Flooding such areas will slow down the decomposition of organic material in the soil and keep the CO2 in the soil rather than allowing it to be released to the atmosphere and contribute to the greenhouse effect. At least, that has been the rationale until now. However, a new study from the University of Copenhagen, published in Nature ...

Twisting upwardly on trees and other plants—along with houses and even lampposts—vines are a wonder of nature. However, their marvels mask their parasitic behavior: in attaching to other life forms, vines block sunlight necessary for growth and strangle their hosts, preventing the flow of water and other nutrients. While these threats were widely known, less clear is what gives vines their searching, attaching, and climbing capabilities.  An international team of scientists has now unlocked a formula that enables vines to search for ...

Physical aggression by young people toward their parents occurs quite frequently – yet the subject remains taboo. Victims often struggle with shame and avoid seeking help, hoping to shield their children from repercussions. Now, in a first-of-its-kind longitudinal study, researchers at the University of Zurich (UZH) have tracked the development of this behavior from early adolescence to young adulthood, identifying which factors increase or reduce the risk.   The research draws on the Zurich Project on Social Development from Childhood to Adulthood (z-proso), directed by Manuel Eisner, Denis Ribeaud and Lilly Shanahan at UZH’s Jacobs Center ...

Electromagnetic pulses (EMPs)—high-energy-density and ultra-wideband beams of electromagnetic radiation—are generated from sources such as nuclear explosions, high-power electromagnetic pulse devices, and intentional electromagnetic interference. These pulses can infiltrate electronic equipment to significantly incapacitate civilian and military electrical, electronic, and communications infrastructures and undermine command, control, communications, computers, intelligence, surveillance, and reconnaissance. In recent years, scientists have explored EMP-shielded exterior glass windows for buildings and transportation systems to address ...

A national clinical trial led by the Alliance for Clinical Trials in Oncology has found that oxybutynin, a drug often used to treat overactive bladder symptoms, reduces hot flashes compared to the placebo in men receiving hormone therapy for prostate cancer. This primary analysis of Alliance A222001 is published in the Journal of Clinical Oncology. “Oxybutynin demonstrated clear and clinically meaningful improvements in both hot flash frequency and quality of life for men undergoing hormone therapy for prostate cancer,” said Bradley J. Stish, MD, the study’s lead investigator and a radiation oncologist ...

By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light – and, as a result, its electronic and optical properties. This is shown by a study from Umeå University published in Nature Communications. Gold plays a crucial role in modern advanced technology thanks to its unique properties. New research now demonstrates that changing the material's physical structure – its morphology – can fundamentally enhance both its electronic behaviour and its ability to interact with light. “This might make it possible to improve the efficiency of chemical reactions such as those used in hydrogen ...

The tool combines a wearable activity tracker (Fitbit watch) with an app that sends helpful messages throughout the day, reminding users ...

Generative AI models have been used to create enormous libraries of theoretical materials that could help solve all kinds of problems. Now, scientists just have to figure out how to make them. In many cases, materials synthes is not as simple as following a recipe in the kitchen. Factors like the temperature and length of processing can yield huge changes in a material’s properties that make or break its performance. That has limited researchers’ ability to test millions of promising model-generated materials. Now, MIT researchers have created an AI model that guides scientists ...

A sediment core from the Pacific sector of the Southern Ocean has provided a research team led by geochemist Dr Torben Struve from the University of Oldenburg, Germany, with evidence of an unexpected climate feedback in Antarctica. As the team reports in the latest issue of Nature Geoscience, there was a close correlation between changes in the West Antarctic Ice Sheet (WAIS) and marine algae growth over previous glacial cycles – but the correlation was not as expected. Based on the results, the team concludes ...

Scientists have created a complete map showing how hundreds of possible mutations in a key cancer gene influence tumour growth. The study focused on CTNNB1, a gene that produces the protein β-catenin, which helps regulate tissue growth and repair. When β-catenin is disrupted, cells can begin uncontrolled growth – a hallmark of cancer. By systematically testing all possible mutations in a priority area of the gene in mouse cells, the map helps explain why certain mutations appear in specific cancers and could guide the development of new treatments, experts say. Many cancers carry mutations ...

A new study in Nature Geoscience reveals that changes in the West Antarctic Ice Sheet (WAIS) closely tracked marine algae growth in the Southern Ocean over previous glacial cycles, but not in the way scientists expected. The key factor is iron-rich sediments transported by icebergs from West Antarctica. Iron acts like fertilizer for algae. But when analyzing a sediment core taken from the Pacific sector of the Southern Ocean in 2001, more than three miles below the water’s surface, researchers were surprised to find that a high iron supply did not accelerate marine algae growth. “Normally, an increased supply of iron in the Southern Ocean would stimulate algae ...
