Cancer patients who undergo chemotherapy could soon benefit from a new AI that is able to identify and predict the development of different combinations of symptoms – helping to alleviate much of the distress caused by their occurrence and severity. In the first study of its kind, published by Nature Scientific Reports, researchers from the University of Surrey and the University of California…
Researchers at the University of Strathclyde have developed an innovative, low cost test for earlier diagnosis of sepsis which could save thousands of lives. The simple system for sensitive real-time measurement of the life threatening condition is much quicker than existing hospital tests, which can take up to 72 hours to process. Using a microelectrode, a biosensor device is used to detect if…
Researchers at Cardiff University have used x-ray crystallography and computer simulation to get a closer look at how viruses bind cells and cause infection. The new insight could help in the development of drugs and therapies for infections and further advance the exploitation of viruses for medical treatments. The first author of the study, Alex Baker from Cardiff University’s School of…
By studying fish raised in aquaculture, researchers from the Helmholtz Zentrum München, the University of Copenhagen and the University of Campinas in Brazil have shed new light on the mechanisms by which antibiotic resistance genes are transferred between bacteria. According to the study published in the journal ‘Microbiome’, those mechanisms are more varied than previously thought. “In…
‘Night owls’ – those who go to bed and get up later – have fundamental differences in their brain function compared to ‘morning larks’ , which mean they could be disadvantaged by the constraints of a normal working day.
A study provides new insight into how the stiffening of breast tissue plays a role in breast cancer development. By examining how mammary cells respond in a stiffness-changing hydrogel, bioengineers at the University of California San Diego discovered that several pathways work together to promote the transformation of breast cells into cancer cells. The work could inspire new approaches to…
In a simulation training study, pediatric team leaders who wore a blindfold improved their leadership skills ratings by 11% over the course of 3 resuscitation scenarios, versus 5% for non-blindfolded leaders. Published in Frontiers in Pediatrics, the findings demonstrate a promising tool for improving training and outcomes in pediatric resuscitation. “Our study suggests that blindfolding the…
The pill could be blurring your social judgement ‒ but perhaps not enough so you'd notice. By challenging women to identify complex emotional expressions like pride or contempt, rather than basic ones like happiness or fear, scientists have revealed subtle changes in emotion recognition associated with oral contraceptive pill (OCP) use. Published in Frontiers in Neuroscience, their study found…
Getting enough sleep is vital to supporting our immune system in fighting off pathogens – this much is common knowledge. But what we don't know is how exactly sleep affects certain immune functions. Scientists at the Universities of Tübingen and Lübeck have now discovered a new mechanism by which sleep supports the immune system. The team led by Dr. Luciana Besedovsky and Dr. Stoyan Dimitrov…
Scientists at Newcastle University believe it may be possible to reverse the damage in the heart caused by ageing. New research, which has been published in the journal EMBO, could suggest a new way of preventing heart failure in older patients. Heart failure occurs when the heart is not pumping blood around the body as well as it should, most commonly when the heart muscle has been damaged –…
Oxford University Radcliffe Department of Medicine researchers have developed a new method that uses a protein originally found in marine corals to visualise the flow of calcium that makes the heart beat. In a paper published in the journal Circulation Research, they used this technique to uncover the effects of genetic errors that contribute to a heart condition that is the leading killer of…
Were Anders Breivik’s actions the work of a madman? Is Theo van Gogh’s killer Mohammed Bouyeri a psychopath? Much is still unclear about the role of psychological disorders (psychopathology) in terrorism. While some research supports the idea that terrorists are mentally ill, other studies contradict this view. In a study commissioned by the Research and Documentation Centre/Dutch Ministry of…
A team of researchers from the Icahn School of Medicine at Mount Sinai and Keck School of Medicine at the University of Southern California (USC) have developed a novel machine-learning framework that distinguishes between low- and high-risk prostate cancer with more precision than ever before. The framework, described in a Scientific Reports paper, is intended to help physicians—in particular,…
Until now, neurologists were largely convinced that having a higher level of education would build some kind of protective barrier against neurodegenerative diseases like Alzheimer's. But a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the online issue of Neurology, the medical journal of the American Academy…
Researchers investigating the effect of cannabis smoking on men’s testicular function have made the unexpected discovery that it is linked to higher sperm counts and higher testosterone levels among moderate users compared to men who never smoked it. The study is published in Human Reproduction, one of the world’s leading reproductive medicine journals. Previous studies had suggested that…
The heart's motion is so powerful that it can recharge devices that save our lives, according to new research from Dartmouth College. Using a dime-sized invention developed by engineers at the Thayer School of Engineering at Dartmouth, the kinetic energy of the heart can be converted into electricity to power a wide-range of implantable devices, according to the study funded by the National…
UC San Francisco researchers have for the first time transformed human stem cells into mature insulin-producing cells, a major breakthrough in the effort to develop a cure for type 1 (T1) diabetes. Replacing these cells, which are lost in patients with T1 diabetes, has long been a dream of regenerative medicine, but until now scientists had not been able to figure out how to produce cells in a…
Nanoparticles can be found in processed food (e.g. food additives), consumer products (e.g. sunscreen) and even in medicine. While these tiny particles could have large untapped potential and novel new applications, they may have unintended and harmful side effects, according to a recent study by researchers from the National University of Singapore (NUS). Specifically, NUS researchers found that…
Activating a neural pathway from the Ventral Tegmental Area (VTA) to the Dorsal Raphe Nucleus (DRN) could significantly reduce morphine addiction while not affecting its analgesic effect, suggests new research led by Prof. Li Xiaoming from Zhejiang University’s School of Medicine. The study, published in the January issue of Neuron, found two parallel inhibitory neural pathways from VTA to DRN:…
For decades, women have shouldered most of the burden of contraception. However, long-term use of female birth control pills could increase the risk for side effects such as blood clots or breast cancer. Now, inspired by colorful layered cocktails, researchers have developed a medium-term, reversible male contraceptive. They report their results in the journal ACS Nano. Common forms of male…
Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a Rutgers-led study in the journal Alcoholism: Clinical & Experimental Research. “We found that people who drink heavily may be changing their DNA in a way that makes them crave alcohol even more,” said Distinguished Professor Dipak K. Sarkar, senior author of…
In a recent study published in the journal Anticancer Research, Saint Louis University scientists, together with a visiting scientist from Fujian Medical University in China, have discovered evidence that oolong tea can lead to DNA damage of breast cancer cells and inhibit the growth and progression of tumors in the lab, potentially offering a non-toxic strategy to prevent breast cancer. The…
Poor sleep has long been linked with Alzheimer’s disease, but researchers have understood little about how sleep disruptions drive the disease. Now, studying mice and people, researchers at Washington University School of Medicine in St. Louis have found that sleep deprivation increases levels of the key Alzheimer’s protein tau. And, in follow-up studies in the mice, the research team has…
Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA. But while losing the plastic tips may lead to messy laces, telomere loss may lead to cancer. Salk Institute scientists studying the relationship of telomeres…
Alzheimer's disease is often marked by a creeping progression: Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tübingen now show that a protein found in the blood can be used…
