A single gene that regulates testosterone levels in a “crazy” species of shore bird controls the development of three wildly different types of males, an international study involving researchers at Simon Fraser University has found.   Ruffs have long fascinated scientists for their three types of males, known as morphs, that differ radically from each other in appearance and mating behaviours.   A new study published on the cover of the journal Science this month has discovered that these morphs are produced by a super enzyme (HSD17B2) ...

Two-thirds of people with post-COVID-19 syndrome have persistent, objective symptoms – including reduced physical exercise capacity and reduced cognitive test performances – for a year or more, with no major changes in symptom clusters during the second year of their illness, according to a new study published January 23rd in the open-access journal PLOS Medicine by Winfried Kern of Freiburg University, Germany, and colleagues. Self-reported health problems following SARS-CoV-2 infection ...

Researchers from Hohai University, Northwestern University, and Politecnico di Milano have introduced a pioneering mesoscale mechanical discrete model, LDPM-MicroF, to simulate the fracture behavior of micro fiber-reinforced concrete (FRC), as reported in Engineering. Microfibers, with diameters less than 100 µm, are crucial in preventing early shrinkage cracking and reducing pore pressure during fires. However, formulating an accurate mechanical constitutive law for micro-FRC has been challenging due to difficulties in understanding ...

Rapid Intensification (RI) of a tropical cyclone (TC), defined as a maximum sustained wind increase of at least 13 m/s within 24 hours, remains one of the most challenging weather phenomena to forecast because of its unpredictable and destructive nature. Although only 5% of TCs experience RI, its sudden and severe development poses significant risks to affected regions. Traditional forecasting methods, such as numerical weather prediction and statistical approaches, often fail to consider the complex environmental and structural factors driving RI. While artificial intelligence ...

Two leading experts in the field of metamaterials from Tsinghua University co-authored a review article on this emerging scientific field in Engineering recently. Unlike traditional review articles, the authors interpret metamaterials from an artistic perspective. By drawing parallels with art, they reflect on significant achievements made over the past two decades and offer insights into the future development of the field. Their work introduces readers to the novel concept of metamaterials as “the art in materials science.” Metamaterials refer to artificially engineered materials composed of structural units designed to exhibit extraordinary ...

Researchers at University of California San Diego analyzed cannabis smoking practices in San Diego County to assess whether in-home smoking was associated with cannabis detection in children. The study, published in the Jan. 23, 2025, online edition of the Journal of the American Medical Association Network Open, found that in-home cannabis smoking increased the odds of child exposure to cannabis smoke. Smoking is the most common method of cannabis use and is known to generate emissions that are harmful to those exposed. Cannabis is often smoked indoors, putting non-smokers such as children at risk for exposure. “While the long-term health consequences of cannabis smoke are not ...

WASHINGTON, Jan. 23, 2025 – Many science fiction authors try to incorporate scientific principles into their work, but Ian Tregillis, who is a contributing author of the Wild Cards book series when he’s not working as a physicist at Los Alamos National Laboratory, took it one step further: He derived a formula to describe the dynamics of the fictional universe’s viral system. In independent research published in the American Journal of Physics, from AIP Publishing, Tregillis and George R.R. Martin derive a formula for viral behavior in the Wild Cards universe. Wild Cards is a science fiction series written by a collection of authors and ...

The remains of the earliest dinosaurs may lie undiscovered in the Amazon and other equatorial regions of South America and Africa, suggests a new study led by UCL (University College London) researchers. Currently, the oldest known dinosaur fossils date back about 230 million years and were unearthed further south in places including Brazil, Argentina and Zimbabwe. But the differences between these fossils suggest dinosaurs had already been evolving for some time, pointing to an origin millions of years earlier. The new study, published in the journal Current Biology, accounted for gaps in ...

About The Study: The results of this retrospective cohort study of 44,000 individuals suggest that fasting plasma glucose level, age, body mass index (BMI), and male sex were all associated with development of diabetes, with significant interaction between these variables. These data contribute to understanding the clinical course of diabetes and highlight the substantial individual variation in diabetes risk according to commonly measured clinical variables. The findings facilitate lifestyle and pharmacologic interventions to treat those at highest risk of diabetes to reduce future morbidity and mortality. Further work is needed to validate this risk ...

About The Study: In this cohort study, food insecurity in pregnancy was associated with a higher risk of perinatal complications, and these associations were overall attenuated to the null among individuals who received food assistance in pregnancy. These findings support clinical guidelines of screening for food insecurity in pregnancy and provide evidence to expand food assistance programs that may help improve maternal and neonatal outcomes.  Corresponding Authors: To contact the corresponding authors, email Rana F.

About The Study: In this cross-sectional study, in-home cannabis smoking was associated with significantly increased odds of child exposure to cannabis smoke, as assessed by urinary cannabinoid biomarkers. As young children spend most of their time at home, reducing in-home cannabis smoking could substantially reduce their exposure to the toxic and carcinogenic chemicals found in cannabis smoke.  Corresponding Authors: To contact the corresponding authors, email Osika Tripathi, PhD (otripath@health.ucsd.edu) and ...

Researchers have found that a newly developed diet inspired by the eating habits of non-industrialised societies can significantly reduce the risk of a number of chronic diseases – and are to share recipes with the public. Industrialised diets—high in processed foods and low in fiber— have contributed to a substantial rise in chronic diseases like obesity, diabetes, and heart disease, in affluent countries such as Ireland. A paper published today in the prestigious scientific journal Cell shows that a newly developed diet that mimics eating habits in non-industrialissed ...

130 years after a fungus-eating plant received its name, a Kobe University researcher has uncovered the purpose of the structure that inspired its name — revealing a novel mechanism by which plants ensure reproduction. MAKINO Tomitaro, a towering figure in Japanese botany, named around 1,000 species and discovered about 600 new plants between 1887 and 1957. Among his notable discoveries was the diminutive orchid Stigmatodactylus sikokianus, first identified in 1889. After Makino’s discovery, the plant was named for the unique, tiny finger-like appendage (the “dactylus” part) on its stigma, the flower’s ...

Genetically tailored treatment plans for children with a type of kidney cancer could help provide the most effective care while minimising side effects as much as possible. Researchers at the Wellcome Sanger Institute, Cambridge University Hospitals NHS Foundation Trust, Great Ormond Street Hospital, the University of Würzburg, and their collaborators, have mapped the genetic differences across children with a type of childhood kidney cancer called Wilms tumour.   In about 30 per cent of children with Wilms tumour, there is an inherited genetic change that increases the risk of developing this cancer. This study, published today (23 January) in Cancer Discovery, ...

WASHINGTON — Researchers have developed a new type of optical memory called a programmable photonic latch that is fast and scalable. This fundamental memory unit enables temporary data storage in optical processing systems, offering a high-speed solution for volatile memory using silicon photonics. The new integrated photonic latch is modeled after a set-reset latch, a basic memory device used in electronic devices to store a single bit by switching between set (1) and reset (0) states based on inputs. “While optical communications and computing have seen significant progress over the past decades, data storage has been predominantly implemented using electronic memory,” ...

A case report published in Eurosurveillance on an adult with an imported case of leprosy in Ireland shows that there are notable challenges in tackling the disease in settings where it is rare. The affected individual was one of five individuals with leprosy reported in Ireland in the past decade. The authors report challenges faced in the public health response due to a delayed recognition of the symptoms by healthcare providers, a lack of specific Irish and European guidelines, and contact tracing in a congregate setting. Ahead of World Leprosy Day, this case study highlights ...

Despite South Florida’s reputation as paradise, the reality for many is stark. In the 2023-24 school year, Broward County reported more than 6,027 homeless children.
