Dr. Thomas Hainmüller and Prof. Dr. Marlene Bartos of the Institute of Physiology of the University of Freiburg have established a new model to explain how the brain stores memories of tangible events. The model is based on an experiment that involved mice seeking a place where they received rewards in a virtual environment.
Recently, scientists have explored another version of embolization, called gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization (ADV), which uses microscopic gas bubbles induced by exposure to ultrasonic waves. A team of researchers from China and France has discovered that these bubbles could also be used as potential drug delivery systems.
T cells fight pathogens and tumors: Researchers from the Universities of Tübingen and Lübeck present a simple and fast method to rapidly assess their function. Due to its simplicity, reliability and versatility, it could be broadly implemented for basic research and in the clinical setting. Methods so far to test T-cell response were technically cumbersome and time-consuming and therefore only…

Researchers have shown for the first time that a form of artificial intelligence or machine learning known as a deep learning convolutional neural network (CNN) is better than experienced dermatologists at detecting skin cancer. In a study published in the leading cancer journal Annals of Oncology, researchers in Germany, the USA and France trained a CNN to identify skin cancer by showing it more…
Clinical trial enrolment favours men, according to a study presented at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology congress.1 The study found that fewer women meet eligibility criteria for trials of heart failure medication. Helena Norberg, author of the study, junior lecturer and PhD student, Umeå University, Sweden, said: “One of the…
When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and early 1990s, MTV had only one format—music videos—and that genre…
Triggers of acute heart failure vary globally, according to late breaking results from the REPORT-HF registry presented at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology congress. REPORT-HF is a global, prospective registry comparing regional differences in causes of acute heart failure, therapies, time to treatment, and outcomes. Professor Sean…
Blood is the juice of life, as while circulating through the body it delivers vital substances such as oxygen and nutrients to cells and tissues. Chemotherapy, radiotherapy and blood loss in general impoverish the system. A special kind of cells in the bone marrow, called hematopoietic stem cells (HSCs) is able to replenish the impoverished system by giving rise not only to red blood cells, but…
Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease. Numerous studies have already shown that a calorie-restricted diet can significantly delay age-related conditions in several organisms like flies, worms, fish and mice, and that it even improves fitness at old age. But who…
Antimicrobial resistance is on the rise worldwide. This is becoming a problem for infectious diseases like tuberculosis as there are only a few active substances available to combat such diseases. Pharmacists at Martin Luther University Halle-Wittenberg (MLU) have now found a way to increase the efficacy of a common tuberculosis agent while, at the same time, reducing resistance to it. The…
Social media often features celebrities drinking cocktails, boozy how-to posts, and party pictures. This is the environment American teens are immersed in every day, with 71 percent of teens using more than one social media site, spending an average of nine hours a day using media. Despite the popularity of social media and alcohol-filled posts, little is known about the influence social media…
People who consume an egg a day could significantly reduce their risk of cardiovascular diseases compared with eating no eggs, suggests a study carried out in China, published in the journal Heart. Cardiovascular disease (CVD) is the leading cause of death and disability worldwide, including China, mostly due to ischaemic heart disease and stroke (including both haemorrhagic and ischaemic…
Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards…
What a difference a year or two can make: If you started smoking marijuana at the start of your teens, your risk of having a drug abuse problem by age 28 is 68 per cent, but if you started smoking between 15 and 17 your risk drops to 44 per cent, according to a new study by Université de Montréal researchers. All the more reason, they say, to educate kids early, in primary school, about the…
The way you walk can reveal current and future health problems. New research from Halmstad University suggests the use of wearable sensors for analysing your movement. This can potentially result in early detection of for example Parkinson’s disease, dementia, multiple sclerosis and other neuro-physiological disorders. Many of our body systems, such as the cardio-vascular system and the…
Could weight loss surgery before knee replacement improve outcomes or even eliminate the need for joint replacement in severely overweight patients? A study by researchers at Hospital for Special Surgery (HSS) aims to answer that question. Orthopedic surgeons often encourage obese patients considering knee replacement to try to lose weight before the procedure. The study, known as SWIFT (Surgical…
A small study of adults with the most common form of pancreatic cancer adds to evidence that patients with BRCA1 or BRCA2 gene mutations long linked to a high risk of breast cancer have poorer overall survival rates than those without the mutations. The same study also found that those with BRCA1 or BRCA2 had better survival rates with platinum-based chemotherapy, compared with similar patients…

At the same time, the trial results were published in the New England Journal of…
Making tumour cells glow: Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in "Communication Physics".
Older adults with mild cognitive impairment (MCI), often a precursor to Alzheimer’s, showed significant improvement with certain complex thinking and memory skills after exergaming, according to a new study. The results could encourage seniors, caregivers and health care providers to pursue or prescribe exergames (video games that also require physical exercise) in hopes of slowing the…
A recently identified pig virus can readily find its way into laboratory-cultured cells of people and other species, a discovery that raises concerns about the potential for outbreaks that threaten human and animal health. Researchers at The Ohio State University and Utrecht University in the Netherlands collaborated to better understand the new virus and its potential reach. Their study, the…
Scientists from the German Cancer Research Center (DKFZ) have been studying how the immune system succeeds in keeping pathogens in check. For the first time, the researchers have now discovered antibodies that are capable of disarming not only one specific bacterium but a whole variety of microorganisms at once. The newly discovered antibodies recognize a tiny sugar structure found on the surface…
Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth and spread of tumors. Now researchers from The Scripps Research Institute are reporting an innovative…
