Scientists have discovered the world's oldest known example of a squid-like creature attacking its prey, in a fossil dating back almost 200 million years.
The fossil was found on the Jurassic coast of southern England in the 19th century and is currently housed within the collections of the British Geological Survey in Nottingham.
In a new analysis, researchers say it appears to show a creature - which they have identified as Clarkeiteuthis montefiorei - with a herring-like fish (Dorsetichthys bechei) in its jaws.
A study in the May 6th issue of Nature indicates the increase in rainfall forecast by global climate models is likely to hasten the release of carbon dioxide from tropical soils, further intensifying global warming by adding to human emissions of this greenhouse gas into Earth's atmosphere.
What The Study Did: The intensive care unit and inpatient bed needs for patients with coronavirus disease 2019 (COVID-19) in two cities in China are described and compared to estimate the peak number of intensive care unit beds needed in U.S. cities if an outbreak equivalent to that in Wuhan occurs.

DALLAS, TEXAS (May 6, 2020) - A new study by an international team from the Perot Museum of Nature and Science in Dallas and Hokkaido University and Okayama University of Science in Japan further explores the proliferation of the most commonly occurring duck-billed dinosaur of the ancient Arctic as the genus Edmontosaurus.
Over the last six years a group of Estonian geneticists led by Associate Professor Agne Velthut-Meikas and a PhD student Ilmatar Rooda from TalTech Department of Chemistry and Biotechnology have studied genes previously associated primarily with female hormone synthesis and ovarian follicle development. The findings suggest that these genes may play a far more complex role in oocyte maturation than previously assumed.
FOSH is rapidly gaining momentum as part of a global "open design movement", whereby the free release of information on customized research hardware, such as design, schematics and bill of materials are easily accessible anywhere with an internet connection.
Quantum technology was once considered to be something very expensive and available only to the largest research centers. However, in our days it's widely used in many applications, and one of them is magnetic resonance imaging.
The public would comply with major changes to medical advice - but would then be less likely to follow other new guidelines in the future, research shows.
High levels of deference towards doctors means most people would obey reformed advice about taking antibiotics. However, the study suggests reforms to public health policy should be made sparingly as this risks undermining future compliance.
The mental well-being of the elderly refers to how they perceive their everyday existence, i.e., if their outlook is positive or negative, which, in turn, makes their life pleasant or unpleasant.
The positive feeling of emotional well-being allows people to live fully and feel integrated in society; moreover, people enjoying good mental health are better capacitated to recover from sudden illness, change or misfortune.
Scientists have made a pivotal breakthrough in advancing our understanding of how bacteria move and perform genetic exchange - that could potentially lead to the development of new antimicrobial drugs.
A team of researchers from the University of Exeter's Living Systems Institute and the University of Frankfurt has made a crucial discovery around the structures of long filaments - hair like appendages - called type IV pili found on the surface of bacteria.
A University of Saskatchewan (USask) research team has uncovered how bats can carry the Middle East respiratory syndrome (MERS) coronavirus without getting sick--research that could shed light on how coronaviruses make the jump to humans and other animals.
Coronaviruses such as MERS, Severe Acute Respiratory Syndrome (SARS), and more recently the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats. While these viruses can cause serious and often fatal disease in people, for reasons not previously well understood, bats seem unharmed.
To restart surgeries cancelled because of the coronavirus disease 2019 (COVID-19) pandemic, Canada needs to adopt single-entry models (SEMs) with team-based care, argues a commentary https://www.cmaj.ca/content/cmaj/early/2020/05/06/cmaj.200791.full.pdf in CMAJ (Canadian Medical Association Journal).
Heart failure and cancer are conditions with a number of shared characteristics. A new study published in the Journal of Internal Medicine found that in patients with heart failure, several known tumor markers can also be indicators of heart failure severity and progression.
In the study, researchers measured six markers that are indicators for various cancers-- including ovarian, breast, lung, pancreatic, colorectal, and germ cell cancers--in 2,079 patients with heart failure.
A study of over 4 million children and adolescents in the U.S. enrolled in Medicaid found that those who rely on urgent care centers for more than a third of their outpatient health care needs had fewer visits to primary care providers. This may result in missed opportunities for preventative services, such as vaccinations, and identification and management of chronic conditions, such as obesity or asthma. Findings were published in JAMA Network Open.
BELTSVILLE, MARYLAND, May 6, 2020--A new freeze-resistant Trichinella species has been discovered in wolverines by Agricultural Research Service scientists and their colleagues. Trichinella are parasites that cause the disease trichinosis (formally referred to as trichinellosis), which people can get by eating raw or undercooked meat from infected animals.
Before the advent of modern biosafety practices, Americans risked infection from a spiralis from contaminated pork. Residual risk exists when consuming wild game infected with this, or other species of Trichinella.
