A study led by researchers at Indiana University is the first to find similarities between the organization of chromosomes in humans and archaea. The discovery could support the use of archaea in research to understand human diseases related to errors in cellular gene expression, such as cancer.
A new study shows that, contrary to widespread belief within the solar power industry, new kinds of solar cells and panels don't necessarily have to last for 25 to 30 years in order to be economically viable in today's market.
Rather, solar panels with initial lifetimes of as little as 10 years can sometimes make economic sense, even for grid-scale installations -- thus potentially opening the door to promising new solar photovoltaic technologies that have been considered insufficiently durable for widespread use.
Oakland, Calif. - Being overweight or obese is commonly associated with diabetes, but a new Kaiser Permanente study finds the connection differs widely by race or ethnicity. Members of racial and ethnic minority groups were much more likely to have diabetes or prediabetes at lower weights -- even at normal or below-normal body mass index (BMI), according to research published in Diabetes Care.
Bottom Line: An analysis of nearly 1.9 million patients diagnosed with breast cancer suggests overall survival is lower among men than women and that undertreatments and clinical characteristics account for much of the difference. The study included National Cancer Database data for 16,025 male and 1.8 million female patients diagnosed with breast cancer between 2004-2014. Men had higher mortality across all breast cancer stages. For men, the three-year survival rate was 86.4% and the five-year survival rate was 77.6%.
More than one million Americans per year experience myocardial infarction, commonly known as a heart attack, as well as the healing and rebuilding phase that begins shortly thereafter - a complicated process which involves remodeling and repairing the heart.
This process is known as the granulation phase and is critical for healing. But due to bodily response in the form of inflammation and scarring, this phase simultaneously reduces cardiac function, significantly increasing the risk of future cardiac events, including heart failure.
Researchers from the Turku Bioscience Centre in Finland have found changes in molecules in the blood that might be new markers of type 1 diabetes. New findings may help understand the early pathogenesis of the disease.
Finland has the highest recorded incidence of type 1 diabetes in children younger than 15 years, and the global prevalence is continuously increasing among the children in many developed countries.
It is known that the real sector of the economy is of paramount importance in the development of any region, in ensuring the growth of its inhabitants' welfare. Recently, Lobachevsky University researchers conducted a case study of Nizhny Novgorod and the Nizhny Novgorod region showing that the situation in the region had improved markedly on one of most important indicators, the volume of investment in fixed assets of industrial enterprises, the essential component of which are machinery and equipment. At the end of 2018, this indicator grew by 5.6%, to 259 billion rubles.
[Introduction]
A new study from the University of Copenhagen reports that the prevalence of overweight dogs is markedly larger among overweight owners than among normal weight owners. Part of the explanation lies in whether treats are used as training tools or "hygge-snacks". It is the first major study on canine obesity in Denmark.
With a study of the network between nerve and muscle cells in turtles, researchers from the University of Copenhagen have gained new insight into the way in which movements are generated and maintained. In the long term, the new knowledge may have an impact on the treatment of, for example, ALS and spinal cord injuries.
For most people, it is easy to put one leg in front of the other and keep walking. The ability to do it is second nature or, so to speak, in our bones. Quite literally.
For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun's surface. They have observed but been unable to explain why the number of spots peaks every 11 years.
A University of Washington study published this month in the journal Physics of Plasmas proposes a model of plasma motion that would explain the 11-year sunspot cycle and several other previously mysterious properties of the sun.
The first extensively drug-resistant (XDR) strains of Salmonella typhimurium, a pathogen which is responsible for millions of bloodstream infections per year in sub-Saharan Africa, have been identified in the Democratic Republic of Congo (DRC). Drug-resistance has increased in successive groups of S. typhimurium over time. These new strains are resistant to all but one of the commonly available drugs in the DRC, with one sample showing reduced susceptibility to this final antibiotic.
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a technique to observe how radiation damages molecules over time-frames of just one quadrillionth of a second - or a femtosecond.
The technique involves dissolving organic molecules in water to simulate the state molecules are found in biological tissue. This allows the research team to see radiation damage occur in biological tissue and molecules with greater precision and clarity than ever before.
Most people consider the hedgehog a welcome guest in the garden. But a newly published study reveals that the Danish hedgehogs carry a secret.
The results have been published in PLOS ONE.
The research was part of a PhD project called "The Danish Hedgehog Project" intending to describe the state of the Danish hedgehog population.
The BBVA Foundation has presented the first module of its European Values Survey 2019, examining a broad set of values and attitudes held by the adult population of five European countries (Germany, the United Kingdom, France, Italy and Spain) in both the public (politics, economics, the media, trust) and private (religion, ethics, science, environment) domains. This press release refers exclusively to the public sphere.
