More than 30 years ago, the European comet mission Giotto flew past Halley's comet. The Bernese ion mass spectrometer IMS, led by Prof. em. Hans Balsiger, was on board. A key finding from the measurements taken by this instrument was that there appeared to be a lack of nitrogen in Halley's coma - the nebulous covering of comets which forms when a comet passes close to the sun. Although nitrogen (N) was discovered in the form of ammonia (NH3) and hydrocyanic acid (HCN), the incidence was far removed from the expected cosmic incidence.
Amsterdam, January 20, 2020 - A new study published in the Journal of Alzheimer's Disease (JAD) supports a growing body of research that links human exposure to aluminum with Alzheimer's disease (AD). Researchers found significant amounts of aluminum content in brain tissue from donors with familial AD.
Nightclubs and bars must create a supportive environment that cracks down on unwanted sexual attention and allows women to enjoy their nights out, according to a new study.
Increasing numbers of women are prepared to speak back to sexual harassment whilst enjoying a night out with female friends by confronting the men responsible and telling them clearly and robustly that their behaviour is unacceptable.
Developing new medicines and understanding how they target specific organs often gives a crucial advantage in the fight against human diseases. An international team led by researchers at the European Molecular Biology Laboratory and Cellzome, a GSK company, has developed a technology to systematically identify drug targets in living animals. In their results, published in Nature Biotechnology on Jan. 20, the scientists mapped protein-drug interactions in rat organs and blood. Their research opens pathways in drug discovery, fundamental biology, and personalized medicine.
The study was led by Rodrigo Ramos Catharino, a professor in UNICAMP's School of Pharmaceutical Sciences.
OAK BROOK, Ill. - The risk of administering modern intravenous iodinated contrast media in patients with reduced kidney function has been overstated, according to new consensus statements from the American College of Radiology (ACR) and the National Kidney Foundation (NKF), published in the journal Radiology.
PITTSBURGH, Jan. 21, 2020 - Commercially insured children in the U.S. are seeing pediatricians less often than they did a decade ago, according to a new analysis led by a pediatrician-scientist at the University of Pittsburgh and UPMC Children's Hospital of Pittsburgh.
But whether that's good or bad is unclear, the researchers say in the study, published today in JAMA Pediatrics.
Simple, no-cost computer changes can affect the number of opioid pills prescribed to patients, according to a new UC San Francisco study.
Researchers found that when default settings, showing a preset number of opioid pills, were modified downward, physicians prescribed fewer pills. Fewer pills could improve prescription practices and protect patients from developing opioid addictions.
BOZEMAN -- A new search led by Montana State University has revealed more than a dozen massive black holes in dwarf galaxies that were previously considered too small to host them, and surprised scientists with their location within the galaxies.
A new approach to reclaiming lands disturbed by surface mining is having the desired result of improving ecosystem diversity, including restoration of foundation species such as sagebrush, according to a study by University of Wyoming researchers.
Precise determination of the chemical structure of a molecule is of vital importance to any molecular related field and is the key to a deep understanding of its chemical, physical, and biological functions. Scanning tunneling microscope and atomic force microscope have outstanding abilities to image molecular skeletons in real space, but these techniques usually lack chemical information necessary to accurately determine molecular structures. Raman scattering spectra contain abundant structural information of molecular vibrations.
Presently, Earth is the only known location where life exists in the Universe. This year the Nobel Prize in physics was awarded to three astronomers who proved, almost 20 years ago, that planets are common around stars beyond the solar system. Life comes in various forms, from cell-phone-toting organisms like humans to the ubiquitous micro-organisms that inhabit almost every square inch of the planet Earth, affecting almost everything that happens on it.
Australian researchers have uncovered a metabolic system which could lead to new strategies for therapeutic cancer treatment.
A team at Flinders University led by Professor Janni Petersen and the St Vincent's Institute of Medical Research have found a link between a metabolic system in a yeast, and now mammals, which is critical for the regulation of cell growth and proliferation.
Gatersleben, 20.01.2020 The development of next-generation-sequencing (NGS) has enabled researchers to investigate genomes that might previously have been considered too complex or too expensive. Nevertheless, the analysis of complex plant genomes, which often have an enormous amount of repetitive sequences, is still a challenge.
Many teenagers are struggling to control their impulses on the internet, in a scramble for quick thrills and a sense of power online, potentially increasing their risks of becoming cyber criminals.
A new study by Flinders Criminology analysed existing links between legal online activities and cybercrime- for example, how viewing online pornography progresses to opening illegal content, and motivations to evolve from online gaming to hacking.
