Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a technique to observe how radiation damages molecules over time-frames of just one quadrillionth of a second - or a femtosecond.
The technique involves dissolving organic molecules in water to simulate the state molecules are found in biological tissue. This allows the research team to see radiation damage occur in biological tissue and molecules with greater precision and clarity than ever before.
Most people consider the hedgehog a welcome guest in the garden. But a newly published study reveals that the Danish hedgehogs carry a secret.
The results have been published in PLOS ONE.
The research was part of a PhD project called "The Danish Hedgehog Project" intending to describe the state of the Danish hedgehog population.
The BBVA Foundation has presented the first module of its European Values Survey 2019, examining a broad set of values and attitudes held by the adult population of five European countries (Germany, the United Kingdom, France, Italy and Spain) in both the public (politics, economics, the media, trust) and private (religion, ethics, science, environment) domains. This press release refers exclusively to the public sphere.
A complicated metabolic syndrome called cachexia is a type of cancer-related muscle wasting disease that can be deadly. The name comes from the Greek words for "bad condition", which is quite descriptive of the health state of patients after a tumor has triggered muscle atrophy in their bodies over a long period.
"The tumor may be in a completely different place than where the affected muscle cells are," says Geir Bjørkøy, a professor at NTNU's Department of Biomedical Laboratory Science, in the Faculty of Natural Sciences.
(Jerusalem, September 19, 2019)--If you could travel back in time to 100,000 years ago, you'd find yourself living among several different groups of humans, including Modern Humans (those anatomically similar to us), Neanderthals, and Denisovans. We know quite a bit about Neanderthals, thanks to numerous remains found across Europe and Asia. But exactly what our Denisovan relatives might have looked like had been anyone's guess for a simple reason: the entire collection of Denisovan remains includes three teeth, a pinky bone and a lower jaw.
People with persistent back pain or persistent headaches are twice as likely to suffer from both disorders, a new study from the University of Warwick has revealed.
The results, published in the Journal of Headache and Pain, suggest an association between the two types of pain that could point to a shared treatment for both.
New confocal reflectance interferometric microscope enables scientists to probe nuclear membrane mechanics within intact cells in a label-free fashion
Nuclear mechanics is known to play a key role in many diseases including cancer metastasis and genetic illnesses such as progeria and muscular dystrophy
The label-free technology does not affect cells, allowing cell screening for therapeutic applications in which cells are injected or implanted into the human body
(Philadelphia, PA) - Like an emergency response team that is called into action to save lives, stress response proteins in the heart are activated during a heart attack to help prevent cell death. As part of this process, Lewis Katz School of Medicine at Temple University researchers show for the first time that one of these specialized emergency responder proteins, known as MCUB, temporarily decreases harmful levels of calcium transport into mitochondria, the energy-generating batteries of cells.
BROOKLYN, NY - It is one of the great unsolved mysteries of anthropology. What killed off the Neanderthals, and why did Homo sapiens thrive even as Neanderthals withered to extinction? Was it some sort of plague specific only to Neanderthals? Was there some sort of cataclysmic event in their homelands of Eurasia that lead to their disappearance?
A new study from a team of physical anthropologists and head & neck anatomists suggests a less dramatic but equally deadly cause.
Toxins produced during harmful algal blooms may be more harmful to people than previously known.
Researchers at The University of Toledo College of Medicine and Life Sciences sought out to examine how microcystin might affect individuals with non-alcoholic fatty liver disease, a widespread condition that is frequently asymptomatic. They found the toxin can significantly amplify the disease at levels below what would harm a healthy liver.
Poor diabetes control was responsible for £3 billion in potentially avoidable hospital treatment in England in the operational year 2017-2018, according to new research comparing the costs of hospital care for 58 million people with and without diabetes.
New research presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain (16-20 Sept) shows that patients with the highest variability in their blood sugar control are more than twice as likely to die as those with the most stable blood sugar measurements. The study is by Professor Ewan Pearson, University of Dundee, UK and Dr Sheyu Li, West China Hospital, Sichuan University, Chengdu, China, and University of Dundee, UK, and colleagues.
Data from the 2019 Monitoring the Future Survey of eighth, 10th and 12th graders show alarmingly high rates of e-cigarette use compared to just a year ago, with rates doubling in the past two years. University of Michigan, Ann Arbor, scientists who coordinate and evaluate the survey released the data early to The New England Journal of Medicine (NEJM) to notify public health officials working to reduce vaping by teens. The survey is funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.
Genesis 36:31 describes an early, pre-10th century BCE Edomite kingdom: "... the kings who reigned in Edom before any Israelite king reigned." But the archaeological record has led to conflicting interpretations of this text.
Now a Tel Aviv University study published in PLOS ONE on September 18 finds that the kingdom of Edom flourished in the Arava Desert in today's Israel and Jordan during the 12th-11th centuries BCE.
Coral reefs and the abundant life they support are increasingly threatened today, but a snapshot of a coral reef that flourished 150 million years ago shows that many animals were then at their peak of diversity, just offshore of the land ruled by dinosaurs.
