A new study led by Swansea University and the University of Bristol has revealed the size of the legendary giant shark Megalodon, including fins that are as large as an adult human.
To date only the length of the legendary giant shark Megalodon had been estimated but now, a new study led by the University of Bristol and Swansea University has revealed the size of the rest of its body, including fins that are as large as an adult human.
Using the Wood Stork, researchers compared city storks with natural wetland storks to gauge their success in urban environments based on their diet and food opportunities. Results provide evidence of how a wetland species persists and even thrives in an urban environment by switching to human foods like chicken wings and hots dogs when natural marshes are in bad shape. These findings indicate that urban areas can buffer a species from the unpredictability of natural food sources.
Sturt Manning is leading investigations into the timelines of ancient events, using tree ring data to refine the widely used radiocarbon dating method.
Noise sensitivity, fear of novel situations and, for example, fear of slippery surfaces and heights are common behavioural problems among dogs.
Variations in a gene called CD38, which is involved in attachment behaviour in non-human animals, may be associated with human romantic relationship dynamics in daily life, according to a study published in Scientific Reports.

Injections of a natural “energy” molecule prompted regrowth of almost half of the cartilage lost with aging in knees, a new study in rodents shows.
Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study.
Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's health. Researchers are developing a method to diagnose brain tumors without any incisions.
Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago discovered that a set of genes with decreased expression in individuals with Down syndrome may lead to clinical abnormalities in this population, such as poor muscle development and heart valve problems. Impairment in these same genes may also protect people with Down syndrome from developing solid tumors. Their findings were published in Scientific Reports.
Infertility is a worldwide clinical problem for human health that affects 8 to 12 percent of couples. A new study from Washington University in St. Louis has implications for understanding some age-related aspects of male reproductive health in primates, including humans. Older male rhesus monkeys sire fewer offspring, even though they appear to be mating as much as younger monkeys with similarly high social status.
Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes.
Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths.
The classic dinosaur family tree has two subdivisions of early dinosaurs at its base: the Ornithischians, or bird-hipped dinosaurs, which include the later Triceratops and Stegosaurus; and the Saurischians, or lizard-hipped dinosaurs, such as Brontosaurus and Tyrannosaurus.
Whale-watching season is delighting the viewing public along the east Australian coast but while it's a boon for the tourism industry, for the majestic humpback whale it's potentially a time of less optimal health.
By analyzing the FDA database of adverse drug effects, UC San Diego researchers discovered that people who received Botox injections — not just in the forehead — reported depression significantly less often than patients undergoing different treatments for the same conditions.
Penn Medicine researchers have shown that federated learning is successful specifically in the context of brain imaging, by being able to analyze magnetic resonance imaging (MRI) scans of brain tumor patients and distinguish healthy brain tissue from cancerous regions.
To fight antibiotic resistance more antimicrobials are needed to treat bacterial biofilms, which protect an infection from antibiotics
Researchers from MIPT and their colleagues from Ural Federal University have combined optical and acoustic approaches and found that incorporating titanium atoms into barium hexaferrite leads to an unexpected substructure forming in the crystal lattice. The resulting material is promising for ultrafast computer memory applications. The findings were published in Scientific Reports.
Microplastics have been found in the guts of sharks that live near the seabed off the UK coast.
New instructions for using nasal sprays may help deliver at least eight times more inflammation-reducing medicine to diseased sinus tissues.
A new method for estimating the biological sex of human remains based on reading protein sequences rather than DNA has been used to study an archaeological site in Northern California.
Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water.
A new study by Kansas State University researchers is the first to confirm that SARS-CoV-2 cannot be transmitted to people by mosquitoes.
Recent studies indicate HIV infection heightens the risk of dental cavities – but a Rutgers researcher has found evidence that the risk of cavities comes not from HIV itself but from a weakened immune system, which could be caused by other diseases.
Blood-feeding livestock mites can be detected with wearable sensor technology nicknamed "Fitbits for chickens."
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.
Microbes found deeper in the ocean are believed to have slow population turnover rates and low amounts of available energy. But microbial communities found deeper in seafloor sediments and around hydrocarbon seepage sites have now been found to have more energy available and a higher population turnover. Deeper sediments in the seepages are most likely heavily impacted by the material coming up from the bottom, which means that the seep could be supporting a larger amount of biomass than previously thought.
Hearing is widely thought to be the last sense to go in the dying process. Now UBC researchers have evidence that some people may still be able to hear while in an unresponsive state at the end of their life.
Artisanal makers of mezcal have a tried and true way to tell when the drink has been distilled to the right alcohol level.
Researchers at McMaster University who study how the brain processes sound have discovered the common practice of using artificial tones in perception experiments could mean scientists are overlooking important and interesting discoveries in the field of brain research

Research from the McKelvey School of Engineering at Washington University in St. Louis has shown that understanding brain activity as a network instead of readings from an EEG allow for more accurate and efficient detection of seizures in real-time.
Chemically engineered peptides, designed and developed by a team of researchers at Rensselaer Polytechnic Institute, could prove valuable in the battle against some of the most persistent human health challenges. The team’s findings, recently published in Nature Scientific Reports, demonstrate how researchers can engineer peptides capable of selectively and specifically binding to polysialic acid (PSA) — a unique carbohydrate that is present on critical human cells and plays a key role in various physiological and pathological processes, including neurological development and disease progression.
A new study investigated the prevalence of activity limitations among older adults in 23 low- and middle-income countries, to help policymakers prepare for the challenges associated with the world’s aging population.
A new study brings neural-level evidence that the continuous variation in natural speech makes the discrimination of phonemes challenging for adults suffering from developmental reading-deficit dyslexia.
With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Picture the sun setting over the ocean.
A study involving Arabian horses from 12 countries found that some populations maintained a larger degree of genetic diversity and that the breed did not contribute genetically to the modern-day Thoroughbred, contrary to popular thought.
Differences in the rate that genetic mutations accumulate in healthy young adults could help predict remaining lifespan in both sexes and the remaining years of fertility in women, according to University of Utah Health scientists. Their study, believed to be the first of its kind, found that young adults who acquired fewer mutations over time lived about five years longer than those who acquired them more rapidly.
A new study highlights a different approach to designing an international climate agreement that would incentivize countries to cooperate.
