A Kobe University research reveals that insect snatching forelimbs have evolved in a similar direction but did not settle on a single solution. The study's framework allowed researchers to quantify the process across lineages and found that different shapes can capture the same ecological function.
A team of international scientists reconstructed size evolution in ancient sharks using interdisciplinary analysis. The study revealed that modern sharks experimented with enormous body sizes much earlier in their evolutionary history than previously suspected.
The superior colliculus, an ancestral brain structure, enables the brain to distinguish objects from the background and detect relevant stimuli in space. It generates centre–surround interactions independently, allowing for the detection of contrasts, edges, and salient features.
A newly-published Cochrane review found significant gaps in clinical rating scales used to assess pain in newborn babies. The review of 79 studies involving over 7,000 infants across 26 countries revealed that none of the available scales are backed by high-quality evidence.
Researchers from Tsinghua University sent 2D materials and field-effect transistors into orbit aboard China's reusable recoverable satellite, Shijian-19. The materials maintained their structural integrity, exhibiting stable switching characteristics after a 14-day space flight.
A new study suggests that US abortion bans are associated with increased fertility rates, particularly among subpopulations experiencing structural disadvantages. The findings also highlight the negative impact of these policies on maternal and child health outcomes.
A new study debunks the long-held Protura-sister hypothesis by revealing critical errors in molecular analysis. The researchers re-examined non-nucleotide sequence data and identified misinterpretations that led to the incorrect grouping of hexapod lineages.
Researchers have uncovered clay tablets with ancient cuneiform writing, game boards, and large structural remains at the ancient Mesopotamian site of Kurd Qaburstan in Iraq. The study sheds new light on literacy, urban development, and social inequality in this Middle Bronze Age city.
Researchers re-examined the taxonomy of a jumping bristletail species found in Japan, uncovering its evolutionary characteristics and shedding light on the transition from aquatic to terrestrial life. The study's findings provide significant insights into early insect evolution and mating behaviors.
A scoping review found associations between myositis disease activity and gluten exposure in patients with inflammatory myopathies and celiac disease. The study suggests that gluten may act as an exogenous antigen driving myositis in genetically predisposed patients.
The study discovered significant alterations in the region's state of stress and deformation following the 1975 Kalapana earthquake. The researchers found that Kīlauea's south flank experienced greater displacement prior to the earthquake, pointing to changes in mechanical properties influencing seismic activity.
A Virginia Tech-led team is searching for signs of dark matter in billion-year-old rocks. By analyzing crystal lattice structures, they aim to uncover miniature trails of destruction left by long-ago dark matter interactions.
A new reconstruction of the 375-million-year-old fossil fish Tiktaalik reveals that its ribs likely attached to its pelvis, enabling support of the body and potentially leading to the evolution of walking. This discovery provides insights into the major evolutionary transition from fish to four-limbed vertebrates.
A study of 205 adolescent football players and 70 noncontact control athletes reveals discernible structural and physiological differences in brain regions associated with mental health. These findings suggest a potential link between football playing and mental health outcomes.
Researchers have observed a first-order structural transition in the impurity phase of cuprous sulfide, providing evidence that LK-99 is non-superconducting. This finding disproves previous claims of room temperature superconductivity and has significant implications for technology.
A study by the University of Delaware found that structural stigma negatively impacts LGB individuals, leading to later coming-out ages and longer closet durations. The research used EU-LGBTI Survey II data from over 137,000 participants across 28 European countries.
A study by Florida Atlantic University and CINVESTAV found that long-term running maintains the connectivity of adult-born hippocampal neurons, which contribute to memory function during aging. Exercise may prevent or delay age-related memory decline by increasing the survival and modifying the network of these neurons.
Researchers from Xi'an Jiaotong-Liverpool University identify vital differences between the plants, including pollinators and lifespan, confirming their classification. The study highlights the importance of recognizing every species for conservation programs.
Research on interventions to mitigate housing insecurity found low-certainty evidence of positive health outcomes, primarily for emergency rent assistance and homeownership assistance. However, existing interventions may need to be paired with other efforts to address structural determinants of health.
A special article in JPHMP presents a pathway for public health departments and practitioners to incorporate law into efforts to advance equity in health outcomes. The article highlights the illustrative case of Coal Run, where residents filed a civil rights complaint and ultimately received water services after decades of denial.
Researchers identified physical binding sites for cholesterol in GIRK channels, which play a role in neurodegenerative diseases. The study provides structural insights into how cholesterol alters channel function, paving the way for drug development.
A new study published in the American Journal of Preventive Medicine highlights the devastating impact of structural racism on the health of foreign-born Blacks and Latinx. Chronic exposure to stressors erodes health, with significant disparities found among these groups compared to US-born individuals.
Fossil insects from Jurassic and mid-Cretaceous periods exhibit structural colors due to wavelength-selective scattering of light. The discovery provides insight into the evolution of lepidopteran scales and their optical properties.
A study by Elliott R. Haut and colleagues found no significant differences in death rates among patients treated by novice vs. experienced trauma surgeons in a structured trauma program. Patients managed by novice surgeons showed improvement in mortality rates after structural changes were implemented.
The Lancet series highlights the importance of combination prevention approaches, combining behavioural, medical, and structural strategies. The authors warn that global prevention efforts are woefully insufficient, with fewer than 10% of individuals at risk receiving key services.
