In a pair of new papers, scientists paint a picture of how solar cycles suddenly die, potentially causing tsunamis of plasma to race through the Sun's interior and trigger the birth of the next sunspot cycle only a few short weeks later.
A team led by Johns Hopkins Kimmel Cancer Center investigators reports that a new laboratory test they developed to identify chemical changes to a group of cancer-related genes can accurately detect which breast tumors are cancerous or benign, and do it in far less time than gold-standard tests on biopsied breast tissue.
While the number of babies who die from sudden infant death syndrome (SIDS) has been on the decline, a study by researchers at Florida Atlantic University's Schmidt College of Medicine and collaborators shows that infant deaths from accidental suffocation and strangulation in bed have more than tripled between 1999 and 2016 in the United States with increases in racial inequalities.
New research, published in The Milbank Quarterly, highlights the potential health and economic impact of the United States (US) Food and Drug Administration's (FDA) proposed voluntary salt policy on workers in the US food industry.
Excess salt consumption is associated with higher risk of cardiovascular disease (CVD). Globally, more than 1.5 million CVD related deaths every year can be attributed to excess dietary salt intake.
Archaeologists of Far Eastern Federal University (FEFU), Institute of Archeology and Ethnography SB RAS (Russia), Escuela Superior Politécnica del Litoral (ESPOL) (Ecuador), and Tohoku University (Japan) found shards of ceramic vessels referred to the cultural sediments of early periods of Real Alto site. Findings date back to 4640 - 4460 BC, this period borders with Valdivia, one of the oldest pottery-featured cultures in North and South America. A related article is published in Antiquity.
A single-molecule imaging technique, called protein-induced fluorescence enhancement (PIFE), has gained traction in recent years as a popular tool for observing DNA-protein interactions with nanometer precision. Yet, according to a new KAUST study, research laboratories have not been using the technique to its fullest potential.
Back in January, CERN released a conceptual report outlining preliminary designs for a Future Circular Collider (FCC), which if built, would have the potential to be the most powerful particle collider the world over. Earlier this month attendees of the 2019 FCC week in Brussels got the first look at what this could look like with the release of the four volume FCC study conceptual design report (CDR).
Trinity College Dublin researchers have found that one in 347 men and one in 436 women can be expected to develop motor neuron disease during their lifetime. Motor neuron disease (MND) is a devastating condition which causes progressive paralysis, increasing physical disability and ultimately death within an average of two to three years. There are over 350 people in Ireland with MND, and one person is diagnosed every 3 days with the condition.
Scientists at the CECAD Cluster of Excellence in Aging Research of the University of Cologne have discovered that body cells which are in direct contact with the germ cells in the nematode Caenorhabditis elegans are responsible for controlling the stability of the genome in primordial germ cells (PGCs). All germ cells, including sperm and eggs, originate from primordial germ cells that form during early embryo development. Professor Dr.
Most people take speech for granted, but it's actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries or other lesions, a person can lose the ability to speak. Now, researchers reporting in ACS Nano have developed a wearable artificial throat that, when attached to the neck like a temporary tattoo, can transform throat movements into sounds.
In order to control cellular processes and thwart the immune system, the bacterium Legionella pneumophilia, the cause of the notorious Legionnaires' disease, releases hundreds of enzymes. Biochemists at Goethe University have now elucidated important details in the interaction of bacterial effectors. They discovered how the regulatory enzyme SidJ keeps other dangerous virulence factors in check.
PHILADELPHIA -- Parkinson's disease often begins with small tremors. Over time symptoms worsen. Tremors become shakes and stiffness takes the body hostage. People with advanced stages of the neurodegenerative disease often have trouble with coordination, walking and maintaining their balance. Currently no cure exists for the condition and available treatments only address symptoms. No therapies are able to slow the progression of the disease yet.
Miami Beach, Fla.--A progressive Emergency Medical Services (EMS)-driven partnership in South Florida has expedited access to lifesaving care for stroke patients. This groundbreaking effort to optimize the likelihood of recovery from a "brain attack" was showcased this week at the Society of NeuroInterventional Surgery's (SNIS) 16th Annual Meeting.
A team from Ruhr-Universität Bochum and the University of Oxford has discovered how hydrogen-producing enzymes, called hydrogenases, are activated during their biosynthesis. They showed how the cofactor - part of the active centre and also the heart of the enzyme - is introduced inside.
Visits to the dentist drop significantly after adults turn 80, finds a new study by researchers at NYU Rory Meyers College of Nursing and the University of Hawai'i at Mānoa.
The study, published online in the journal Research on Aging, also highlights disparities in dental visits for U.S. adults by race and country of birth, with immigrants and racial and ethnic minorities less likely to access care.
