Unravelling an ancient European extinction mystery: Disappearance of dwarf megafauna on palaeolithic Cyprus

Scientists have unravelled a mystery about the disappearance of dwarf hippos and elephants that once roamed the picturesque landscape on the Mediterranean island of Cyprus before palaeolithic humans arrived. Cyprus only had two species of megafauna present during the Late Pleistocene — the 500-kg dwarf elephant (Palaeoloxodon cypriotes), and the 130-kg dwarf hippo (Phanourios minor), but both species disappeared soon after humans arrived around 14,000 years ago. In examining the reasons behind the extinction of these prehistoric animals, research funded by the European Regional Development Fund and the Republic of Cyprus through the Research and Innovation Foundation ...

Highly-sensitive beaks could help albatrosses and penguins find their food

Researchers have discovered that seabirds, including penguins and albatrosses, have highly-sensitive regions in their beaks that could be used to help them find food. This is the first time this ability has been identified in seabirds. An international team of researchers, led by the University of Cambridge, studied over 350 species of modern birds and found that seabirds have a high density of sensory receptors and nerves at the tip of their beaks, which has been previously identified in specialised tactile foragers such as ducks. The researchers say this touch-sensitive region could have come from a common ancestor, and further work is needed to determine ...

New research shows how oral cancer cells avoid immune system

Macquarie University researchers have discovered new information about how oral cancer cells may block the body's immune response. This could lead to better treatments for this aggressive disease. Their research, published in the Journal of Oral Biosciences this month, looked at protein interactions in oral cancer cells that might stop our immune cells from attacking these tumours. Oral cancer is the sixth most common cancer in Australia and the most common in India. Advanced forms of oral cancer are hard to treat, with patients typically surviving less than 12 months. Lead author Dr Rajdeep Chakraborty from Applied Biosciences ...

Abnormal electrolyte levels in people with eating disorders may increase risk of death, poor health outcomes

Ottawa, ON, September 17, 2024 – A new study published in The Lancet Psychiatry found that 32% of individuals with an eating disorder had abnormal electrolyte levels, which were associated with a higher risk of death from any cause.  The study, led by researchers at ICES and The Ottawa Hospital, found that electrolyte abnormalities were also linked to the development of other serious health conditions, including chronic kidney disease, bone fracture, bowel obstruction, and acute kidney injury.  This is one of the first large, population-based studies to identify an important risk factor for mortality and poor health outcomes in individuals ...

No major concerns about risks to offspring for would-be dads taking epilepsy meds

Would-be dads taking drugs to stop their epilepsy seizures—and valproate in particular—should be largely reassured that the available evidence on the developmental risks to their offspring doesn’t justify any major concerns, concludes a systematic review of relevant studies published online in the Journal of Neurology Neurosurgery & Psychiatry. The available evidence is scarce and inconsistent, but most studies indicate no heightened risk, the findings show, casting doubt on the stance taken by the UK drugs regulator, the MHRA, in particular, say ...

Fifth of GPs using AI despite lack of guidance or clear work policies, UK survey suggests

A fifth of family doctors (GPs) seem to have readily incorporated AI into their clinical practice, despite a lack of any formal guidance or clear work policies on the use of these tools, suggest the findings of an online UK-wide snapshot survey, published in the open access journal BMJ Health & Care Informatics. Doctors and medical trainees need to be fully informed about the pros and cons of AI, especially because of the inherent risks of inaccuracies (‘hallucinations’), algorithmic biases, and the potential to compromise patient privacy, ...

USC launches large-scale nationwide study of type 1 diabetes and brain development

About half of adults with type 1 diabetes face significant cognitive impairment, including problems with working memory and executive function that affect day-to-day thinking. But less is known about how the condition affects children during a window of time known to be critical for healthy brain development. A new large-scale longitudinal study, led by the Keck School of Medicine of USC, will unite 12 research centers across the United States to explore that important question. Researchers will collaborate to recruit a large, diverse group of children newly diagnosed with diabetes, taking a sweeping look at the environmental, lifestyle, ...

Ancestry-specific genetic variants linked to multiple sclerosis risk, new study shows

A landmark study has uncovered novel ancestry-specific genetic variants linked to multiple sclerosis (MS), offering new insights that could reshape treatment approaches for diverse populations affected by the disease.1 The research, presented today at ECTRIMS 2024, is the result of efforts by the Alliance for Research in Hispanic MS (ARHMS) Consortium and is the first large-scale study to identify ancestry-specific genetic effects for MS risk. In a comprehensive analysis of over 7,000 individuals from self-reported Hispanic (n=4,313; 2,201 MS, 2,112 controls) and African American (n=3,085; 1,584 MS, 1,501 controls) backgrounds, researchers discovered ...

Early high-efficacy treatment significantly reduces long-term disability in children with multiple sclerosis, new study finds

New research presented today at ECTRIMS 2024 reveals that initiating monoclonal antibody therapy during childhood, rather than delaying treatment until early adulthood, significantly reduces long-term disability in multiple sclerosis (MS) patients.1 The study, which utilised data from the French MS Registry, Italian MS Register, and the global MSBase Registry, analysed the outcomes of 282 patients with paediatric-onset MS who began experiencing symptoms before the age of 18 years. Patients were divided into two groups based on when they initiated monoclonal antibody treatment: either ...

Browser extensions, the software add-ons that help users customize and enhance their web browsers, are wildly popular. Some of the most-used extensions find shopping deals, fix grammar and typos, manage passwords, or translate web pages. The types of extensions available are nearly endless, and many have become indispensable tools for businesses and everyday users.  While these extensions can make web browsing more accessible, productive, and rewarding, they are not without risk. New research from Georgia Tech reveals that thousands of browser extensions pose significant threats to privacy, and hundreds automatically ...

Building better DNA editors: Retrons raise the bar for gene research

SAN FRANCISCO—Within bacterial cells, specialized immune systems known as retrons fend off viral attacks. But that’s not all they can do. Scientists, including Seth Shipman, PhD, at Gladstone Institutes, have shown that retrons also serve an important purpose in the lab: precise DNA editing. In fact, retrons can be combined with CRISPR—the far more famous bacterial-defense-system-turned-gene-editor—to better edit human cells. Yet, for all their potential to help scientists better understand disease and develop new therapies, only a small number of retrons have been studied. In nature, many thousands of variations exist, some with greater gene-editing powers than ...

Mapping out matter’s building blocks in 3D

NEWPORT NEWS, VA – Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom’s nucleus — particles called hadrons that a high school student would recognize as protons and neutrons — are made up of a seething mixture of interacting quarks and gluons, known collectively as partons. A group of physicists has now come together to map out these partons and disentangle how they interact to form hadrons. Based at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility and known as the HadStruc Collaboration, these ...
