NASA's Aqua satellite passed over the Eastern Pacific Ocean and provided an image of Hurricane Juliette as its eye began to emerge. Juliette has grown into a major hurricane, about 450 miles southwest of the southern tip of Baja California, Mexico.
Juliette developed on Sunday, Sept 1 around 5 a.m. EDT (0900 UTC) as a tropical storm. By 5 p.m. EDT on Sept. 2, the storm had strengthened into a hurricane.
Despite a broad campaign among physician groups to reduce the amount of imaging in medicine, the rates of use of CT, MRI and other scans have continued to increase in both the U.S.
Despite a broad campaign among physician groups to reduce the amount of imaging in medicine, the rates of use of CT, MRI and other scans have continued to increase in both the U.S. and Ontario, Canada, according to a new study of more than 135 million imaging exams conducted by researchers at UC Davis, UC San Francisco and Kaiser Permanente. This concerns researchers because medical imaging is widely believed to be overused.
A deep drilling project at Lake Ohrid, situated at the border between Albania and North Macedonia and involving 47 researchers from 13 nations, has brought new insights into climate history to light. The team, headed by the geologist Professor Dr Bernd Wagner from the University of Cologne, has now published its findings under the title 'Mediterranean winter rainfall in phase with African monsoon during past 1.36 million years' in 'Nature'.
Researchers have shed new light on how some geese can fly high for long periods of time, according to a study published today in eLife.
The team collected the first ever cardiorespiratory measurements of bar-headed geese flying in a wind tunnel at a simulated altitude of 9,000m. They discovered that the animals are able to maintain flight in these low-oxygen conditions via a reduction in their metabolism.
A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
The team's research has now identified several avenues by which ringed molecules known as polycyclic aromatic hydrocarbons, or PAHs, can form in space. The latest study is a part of an ongoing effort to retrace the chemical steps leading to the formation of complex carbon-containing molecules in deep space.
CAMBRIDGE, Mass. - The utterances of Old World monkeys, some of our primate cousins, may be more sophisticated than previously realized -- but even so, they display constraints that reinforce the singularity of human language, according to a new study co-authored by an MIT linguist.
The following papers will be presented at the ESC Congress 2019, organised by the European Society of Cardiology in Paris and published simultaneously in either The Lancet or The Lancet Global Health journals. All papers are under embargo until the stated time. Contact details for corresponding authors are provided in the Articles and linked Comments. Funding information is listed on the first page of each Article.
Mothers who are dissatisfied with their male partners spend more time talking to their infants - but only if the child is a boy, according to a new study from researchers at the University of Cambridge.
A previously unknown type of light wave has been discovered by researchers, based on the pioneering work of a 19th century Scottish scientist.
Equations developed by renowned mathematician and physicist James Clerk Maxwell have helped to reveal how crystals can be manipulated to produce a distinctive form of light wave.
The phenomena - recently named Dyakonov-Voigt waves - could have a range of useful applications, such as improving biosensors used to screen blood samples or developing fibre optic circuits that transfer data more efficiently.
University of Cambridge researchers have shown that an algorithm can predict the outcomes of complex chemical reactions with over 90% accuracy, outperforming trained chemists. The algorithm also shows chemists how to make target compounds, providing the chemical 'map' to the desired destination. The results are reported in two studies in the journals ACS Central Science and Chemical Communications.
Animals have adapted to diverse thermal environments from cold to hot. During the course of thermal adaptation processes, preferred thermal ranges for survival shift among species adapted to different thermal niches. Accordingly, evolutionary changes of thermal perception must be required during thermal adaptation. To understand the molecular basis for the shift in thermal perception, the researchers compared the functional properties of thermal sensors among clawed frog species adapted to different thermal niches in Africa.
New research has found that habitat loss is a major concern for hundreds of Australian bird species, and south-eastern Australia has been the worst affected.
The Threatened Species Recovery Hub study, featuring University of Queensland scientists, found that half of all native bird species have each lost almost two-thirds of their natural habitat across Victoria, parts of South Australia and New South Wales.
Lead researcher, Dr Jeremy Simmonds, said the team looked at both threatened and non-threatened birds, including common species.
Paris, France - 3 Sept 2019: Nearly one-third of patients with an implantable cardioverter defibrillator (ICD) resume driving despite it being medically contraindicated - a practice that is dangerous for themselves and others, and is illegal in some countries. The Danish research is presented today at ESC Congress 2019 together with the World Congress of Cardiology.(1)
Protein aggregates have been observed in the nerve tissue of patients with Parkinson's disease which consist of individual components (monomers) of the protein α-synuclein which assemble into what are referred to as amyloid fibrils. Similar deposits are also found in the case of other neurodegenerative diseases such as Alzheimer's. Researchers are looking for approaches to prevent fibril formation and potentially cure the diseases.
