Jurassic fossils from northeastern China reveal morphological stasis in the catkin-yew
160,892 articles from EurekAlert
Dong and colleagues studied well-preserved plant fossils from the Middle-Late Jurassic Daohugou Bed in eastern Inner Mongolia, northeastern China. These fossils closely resemble the extant catkin-yews Amentotaxus. They provide unequivocal evidence that the catkin-yews have undergone little morphological change over at least ~160 million years. Like ginkgo, the catkin-yews are living fossils that...

Alaskan volcano linked to mysterious period with extreme climate in ancient Rome
Researchers from the Center for Diagnostics and Telemedicine together with colleagues from Mayo Clinic College of Medicine and Science, University of Munich and Sechenov University used computed tomography to analyze the individual anatomy of the nasolabial triangle. They identified possible options for the distribution of blood vessels on three-dimensional course.
An early morning whey protein snack increases morning blood sugar level in healthy people
The cold, famine and unrest in ancient Rome and Egypt after the assassination of Julius Caesar in 44 BCE has long been shrouded in mystery. Now, an international team, including researchers from the University of Copenhagen, has found evidence suggesting that the megaeruption of an Alaskan volcano may be to blame.
Arctic Ocean changes driven by sub-Arctic seas
Consuming protein at night increases blood sugar level in the morning for healthy people, according to new research presented this week at The Physiological Society's virtual early career conference called Future Physiology 2020.
Basel study: Why lopinavir and hydroxychloroquine do not work on COVID-19
New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.
Black phosphorus-based van der Waals heterostructures for mid-infrared light-emission applications
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the...
BU researchers: 'Gun culture 3.0' is missing link to understand US gun culture
Optically- and electrically- driven mid-infrared (MIR) light-emitting devices are realized in a simple but novel van der Waals (vdW) heterostructure, constructed from thin-film black phosphorus (BP) and transition-metal dichalcogenides (TMDC). This work suggests that vdW heterostructure is a promising platform for mid-infrared research and applications.
Collective behavior research reveals secrets of successful football teams
A new Boston University School of Public Health (BUSPH) study published in the Nature journal Humanities & Social Sciences Communications, shows that gun ownership means very different things in different parts of the United States.
Columbia physicians give first comprehensive review of COVID-19's effects outside the lung
Collective behaviour researchers have applied a new tool for analysing the movement of football players that goes beyond looking at individual athletes to capturing how the team operates as a whole. The tool, which comes from statistical physics but has never been used for sports analysis, finds clear differences in collective dynamics between winning and losing teams and can even predict the...
Commentary in Pediatrics: Children don't transmit Covid-19, schools should reopen in fall
Based on their experience treating COVID-19, Columbia physicians have assembled critical information about the coronavirus's effects on organs outside the lungs.
Construction: How to turn 36 seconds into USD 5.4 billion
Based on one new and three recent studies, the authors of this commentary in Pediatrics conclude that children rarely transmit Covid-19, either among themselves or to adults. Based on the evidence, the authors recommend that schools reopen in the fall, since staying home can adversely affect children's development.
Couldn't socially distance? Blame your working memory
A team of researchers from Aarhus University have, for the first time ever, linked 40 years of productivity data from the construction industry with the actual work done. The results show that productivity in the construction industry has been declining since the 1970s. The results also explain the decline and how to achieve far more efficient construction in North America and Europe. The study...
COVID-19 can be transmitted in the womb, reports pediatric infectious disease journal
Whether you decided to engage in social distancing in the early stages of COVID-19 depended on how much information your working memory could hold. Researchers found individuals with higher working memory capacity have an increased awareness of benefits over costs of social distancing and show more compliance with recommended social distancing guidelines during the early stage of the COVID-19...
Day in, day out: Targeting the daily magnesium "rhythm" can optimize crop yield
A baby girl in Texas -- born prematurely to a mother with COVID-19 -- is the strongest evidence to date that intrauterine (in the womb) transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur, reports The Pediatric Infectious Disease Journal, the official journal of The European Society for Paediatric Infectious Diseases. The journal is published in the Lippincott...
Discovery of a novel drug candidate to develop effective treatments for brain disorders
Many processes of photosynthesis, including the intake of magnesium, follow a pattern of variation over 24 hours. In a new study, scientists from Okayama University, Japan and Fujian A & F University, China, tested the effect of this variation on the efficiency of photosynthesis in rice plants. Their findings suggest potential candidates for modification for increasing the yield of rice crops,...
Experts, advocates publish guidance for research on HIV, co-infections in pregnancy
Researchers at IIT-Istituto Italiano di Tecnologia discovered a novel chemical compound, which has the potential to became a new drug for the treatment of core symptoms of brain disorders like Down syndrome and autism. Results are obtained in preclinical models where the new compound ameliorated difficulties in cognitive tasks, social interactions and repetitive behaviors. Researchers aim to...
Extraordinary regeneration of neurons in zebrafish
Changing practices in the HIV/co-infections research community so that women, providers, and policy makers can make evidence-informed decisions around the use of medications during pregnancy is the goal of the new report, Ending the Evidence Gap for Pregnant Women around HIV and Co-infections: A Call to Action, issued today by the Pregnancy and HIV/AIDS: Seeking Equitable Study (PHASES) Working...
Farmers' climate change conundrum: Low yields or revenue instability
Biologists from the University of Bayreuth have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish. They studies the Mauthner cells, which are solely responsible for the escape behaviour of the fish, and previously regarded as incapable of regeneration. However, their ability to regenerate crucially depends on the...
Climate change will leave some farmers with a difficult conundrum, according to a new study by researchers from Cornell University and Washington State University: Either risk more revenue volatility, or live with a more predictable decrease in crop yields.
