Cardiologists establish how e-cigarettes damage the brain, blood vessels and lungs

Credit: European Heart Journal Cardiologists have issued a stark warning about the dangers of e-cigarettes, particularly for young people, as results of new research show the damage they cause to the brain, heart, blood vessels and lungs. The study, which is published in the European Heart Journal [1] today (Wednesday), also identifies some of the mechanisms involved, for which there has been limited information up until now. Professor Thomas Münzel,

Study investigates a critical transition in water that remains liquid far below 0 °C

The theoretical model proposed by Brazilian researchers can be applied to any system in which two energy scales coexist Credit: Miguel Boyayan/Revista Pesquisa FAPESP Water can remain liquid at temperatures far below 0 °C. This phase is known as supercooled and is a current focus for scientific research. A theoretical model developed at São Paulo State University (UNESP) in Brazil shows that in supercooled water, there is a critical point

Early dispersal for quadrupedal cetaceans: amphibious whale from middle Eocene

Early dispersal for quadrupedal cetaceans: an amphibious whale from the middle Eocene of the southeastern Pacific Credit: O. Lambert. Scientists have a relatively precise idea about where whales and their closest terrestrial relatives evolved more than 50 million years ago (early Eocene), thanks to the discovery of ancient cetacean fossils in India and Pakistan. Around 45 million years ago, four-legged whales (protocetids) gradually dispersed out of Asia, westward towards Africa

What and how much we eat might change our internal clocks and hormone responses

Credit: @Helmholtz Zentrum München / Uhlenhaut. The research conducted in mice found that the time-of-day dependent metabolic cycle is altered by high caloric diet. Since glucocorticoids are widely used drugs for the treatment of inflammatory diseases, these findings published in Molecular Cell suggest that lean and obese patients might respond differently to steroid therapy. Finally, it reveals the biological function of daily rhythms of hormone secretion (high before awakening and

New sphenisciform fossil further resolves bauplan of extinct giant penguins

A new sphenisciform fossil from the north island of New Zealand further resolves the bauplan of extinct giant penguins Credit: Simone Giovanardi Penguins are descendants of seabirds that lost the ability to fly more than 60 million years ago in exchange for chasing the abundant food available in the ocean. New Zealand is a key area for understanding the diversity of the extinct penguins and has even revealed the existence

Choosing most cost-effective practices for sites could save in bay cleanup

Credit: Sue Morgan Using site-specific watershed data to determine the most cost-effective agricultural best management practices — rather than requiring all the recommended practices be implemented across the entire watershed — could make staying below the Chesapeake Bay’s acceptable pollution load considerably less expensive. That’s the conclusion of a novel, five-year study conducted by an interdisciplinary team of Penn State and U.S. Department of Agriculture researchers, who modeled and compared

Civil engineering professor recognized for impact on sustainable urban development

A global expert on landfill management Credit: UT Arlington Sahadat Hossain’s passion is trash. The environmental and civil engineering professor at The University of Texas at Arlington is a globally recognized expert on landfill management and what society does with landfills and the trash that is in them. The International Solid Waste Association (ISWA) recently honored Hossain for his outstanding contributions to the field and his continuous efforts to educate

Study shows invasive blue catfish can tolerate high salinities

Indicates potential for further expansion in Chesapeake and into Delaware Bay Credit: © VIMS Trawl Survey. A new study by researchers at the Virginia Institute of Marine Science warns that blue catfish–an invasive species in several Chesapeake Bay tributaries–tolerate salinities higher than most freshwater fishes, and thus may be able to expand their range downstream into mainstem Chesapeake waters, and from there into new Bay tributaries and even Delaware Bay.

2019 ESMO Award for Immuno-Oncology goes to Thomas Gajewski

ESMO Immuno-Oncology Congress, Dec. 11-14, 2019, Geneva, Switzerland Credit: © European Society for Medical Oncology Lugano, Switzerland, 5 November 2019 – The European Society for Medical Oncology (ESMO) has selected Prof. Thomas Gajewski to receive the 2019 ESMO Award for Immuno-Oncology (1). The award is given in recognition of his groundbreaking work elucidating why some patients are resistant to immunotherapy and how to restore the anti-cancer immune response. The award

Discriminating diets of meat-eating dinosaurs

Credit: Joep Schaeffer A big problem with dinosaurs is that there seem to be too many meat-eaters. From studies of modern animals, there is a feeding pyramid, with plants at the bottom, then plant-eaters, and then meat-eaters at the top. A new study by scientists at the University of Bristol’s School of Earth Sciences, published in the journal Palaeontology, shows that dinosaurian meat-eaters, the theropod dinosaurs, specialised a great deal,
