Risk-taking linked to particular brain features

2021-01-28
Risky behaviors such as smoking, alcohol and drug use, speeding, or frequently changing sexual partners result in enormous health and economic consequences and lead to associated costs of an estimated 600 billion dollars a year in the US alone. In order to define measures that could reduce these costs, a better understanding of the basis and mechanisms of risk-taking is needed. Functional and anatomical differences UZH neuro-economists Goekhan Aydogan, Todd Hare and Christian Ruff, together with an international research team looked at the genetic characteristics that correlate with risk-taking behavior. Using a representative sample of 25,000 people, the researchers examined the relationship ...

First mammography screening guidelines issued for older survivors of breast cancer

2021-01-28
BOSTON - A nationwide panel of experts has developed the first mammography guidelines for older survivors of breast cancer, providing a framework for discussions between survivors and their physicians on the pros and cons of screening in survivors' later years. The guidelines, published online today in a paper in JAMA Oncology, recommend discontinuing routine mammograms for survivors with a life expectancy under five years; considering stopping screening for those with a 5-10-year life expectancy; and continuing mammography for those whose life expectancy is greater than 10 years. The guidelines will be complemented by printed materials to help survivors gauge their risk of cancer recurring in the breast and weigh the potential benefits and drawbacks of mammography with ...

How evolution can change science for the better

How evolution can change science for the better
2021-01-28
Science is society's best method for understanding the world. Yet many scientists are unhappy with the way it works, and there are growing concerns that there is something "broken" in current scientific practice. Many of the rules and procedures that are meant to promote innovative research are little more than historical precedents with little reason to suppose they encourage efficient or reliable discoveries. Worse, they can have perverse side-effects that harm both science and scientists. A well-known example is the general preference for positive over negative results, which creates a "publication bias" that gives the false ...

Study reveals cause of common Zika virus birth defect

Study reveals cause of common Zika virus birth defect
2021-01-28
CLEVELAND - Cleveland Clinic researchers have described for the first time how Zika virus (ZIKV) causes one of the most common birth defects associated with prenatal infection, called brain calcification, according to new study findings published in Nature Microbiology. The findings may reveal novel strategies to prevent prenatal ZIKV brain calcification and offer important insights into how calcifications form in other congenital infections. "Brain calcification has been linked to several developmental defects in infants, including motor disorders, cognitive disability, eye abnormalities, hearing deficits and seizures, so it's important to better understand the mechanisms of how they develop," said Jae Jung, ...

Rare genetic syndrome identified, caused by mutations in gene SATB1

2021-01-28
Advances in DNA sequencing have uncovered a rare syndrome which is caused by variations in the gene SATB1. The study, co-authored by academics from Oxford Brookes University (UK), University of Lausanne (Switzerland), Radboud University (The Netherlands), University of Oxford (UK), University of Manchester (UK) and led by Max Planck Institute for Psycholinguistics (The Netherlands), discovered three classes of mutations within the gene SATB1, resulting in three variations of a neurodevelopmental disorder with varying symptoms ranging from epilepsy to muscle tone abnormalities. Recognition of disorder will increase understanding and diagnosis An international team of geneticists and clinicians from 12 countries identified 42 patients with mutations in the gene ...

Sleep disorders: Patients often underestimate their total sleep time

2021-01-28
People with sleep disorders commonly have a misperception about their actual sleep behaviour. A research group led by Karin Trimmel and Stefan Seidel from MedUni Vienna's Department of Neurology (Outpatient Clinic for Sleep Disorders and Sleep-Related Disorders) analysed polysomnography results to identify the types of sleep disorder that are associated with a discrepancy between self-reported and objective sleep parameters and whether there are any factors that influence this. The main finding: irrespective of age, gender or screening setting, insomnia patients are most likely to underestimate how long they sleep. The study has been published in the highly regarded Journal of Clinical Sleep Medicine. Patients' misperceptions about the actual time that they sleep is a well-known ...

Efficient fluorescent materials and OLEDs for the NIR

Efficient fluorescent materials and OLEDs for the NIR
2021-01-28
The ability to manipulate near-infrared (NIR) radiation has the potential to enable a plethora of technologies not only for the biomedical sector (where the semitransparency of human tissue is a clear advantage) but also for security (e.g. biometrics) and ICT (information and communication technology), with the most obvious application being to (nearly or in)visible light communications (VLCs) and related ramifications, including the imminent Internet of Things (IoT) revolution. Compared with inorganic semiconductors, organic NIR sources offer cheap fabrication over large areas, mechanical flexibility, conformability, ...

New ion trap to create the world's most accurate mass spectrometer

New ion trap to create the worlds most accurate mass spectrometer
2021-01-28
Mass spectrometers are widely used to analyze highly complex chemical and biological mixtures. Skoltech scientists have developed a new version of a mass spectrometer that uses rotation frequencies of ionized molecules in strong magnetic fields to measure masses with higher accuracy (FT ICR). The team has designed an ion trap that ensures the utmost resolving power in ultra-strong magnetic fields. The research was published in the journal Analytical Chemistry. The ion trap is shaped like a cylinder made up of electrodes, with electric and magnetic fields generated inside. The exact masses of the test sample's ions can be determined from their rotation frequencies. The electrodes must create a harmonized field of a particular shape ...

Skoltech team developed on-chip printed 'electronic nose'

Skoltech team developed on-chip printed electronic nose
2021-01-28
Skoltech researchers and their colleagues from Russia and Germany have designed an on-chip printed 'electronic nose' that serves as a proof of concept for low-cost and sensitive devices to be used in portable electronics and healthcare. The paper was published in the journal ACS Applied Materials Interfaces. The rapidly growing fields of the Internet of Things (IoT) and advanced medical diagnostics require small, cost-effective, low-powered yet reasonably sensitive, and selective gas-analytical systems like so-called 'electronic noses.' These ...

Wood formation can now be followed in real-time -- and possibly serve the climate of tomorrow

Wood formation can now be followed in real-time -- and possibly serve the climate of tomorrow
2021-01-28
A genetic engineering method makes it possible to observe how woody cell walls are built in plants. The new research in wood formation, conducted by the University of Copenhagen and others, opens up the possibility of developing sturdier construction materials and perhaps more climate efficient trees. The ability of certain tree species to grow taller than 100 meters is due to complex biological engineering. Besides needing the right amounts of water and light to do so, this incredible ability is also a result of cell walls built sturdily enough to keep a tree both upright and able to withstand the tremendous pressure created as water is sucked up from its roots and into its leaves. This ability is made possible by what are known as the secondary cell ...
