The idea Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of life, but it is associated with a greatly increased incidence of most chronic diseases, including various cancers, diabetes, and Alzheimer’s disease. The laboratory of Kris Burkewitz, assistant professor of cell and developmental biology, wants to figure out if there is a way to break the links between the aging process and disease so that we can stay healthy longer, allowing ...

Toronto, ON, February 2, 2026 — A new study suggests that people born more recently are being diagnosed with psychotic disorders (e.g., schizophrenia) more often and at younger ages compared with people born earlier.   The study included over 12 million individuals who were born between 1960 and 2005 and followed them for new diagnoses of a psychotic disorder between 1993 and 2023. Over the study, 152,587 individuals were diagnosed with a psychotic disorder. Researchers from ICES, North York General, The Ottawa Hospital, and Bruyère Health Research Institute found that the rate of new diagnoses of psychotic disorders ...

About The Study: In 2021-2023, most U.S. adults with uncontrolled blood pressure (BP) were not taking antihypertensive medication. Approximately two-thirds of U.S. adults with uncontrolled BP who were not taking antihypertensive medication had systolic BP and diastolic BP within 10 mm Hg of the 2025 AHA/ACCBP goal, indicating that many could potentially achieve BP control with initiation of antihypertensive medication and lifestyle modification.

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 ...
