SpaceX rocket ship lifts off with 2 Americans (Update)

A rocket ship built by Elon Musk's SpaceX company thundered away from Earth with two Americans on Saturday, ushering in a new era of commercial space travel and putting NASA back in the business of launching astronauts from U.S. soil for the first time in nearly a decade.

Scientists develop method to help epidemiologists map spread of COVID-19

Rochester Institute of Technology scientists have developed a method they believe will help epidemiologists more efficiently predict the spread of the COVID-19 pandemic. Their new study, published in Physica D: Nonlinear Phenomena, outlines a solution to the SIR epidemic model, which is commonly used to predict how many people are susceptible to, infected by, and recovered from viral epidemics.

Mergers between galaxies trigger activity in their core

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. They were able to compile about 10 times more pictures of merging galaxies than previous studies by using a machine-learning algorithm.

Heightened interaction between neolithic migrants and hunter-gatherers in Western Europe

The Neolithic lifestyle, including farming, animal domestication and the development of new technologies, emerged in the Near East around 12,000 years ago and contributed profoundly to the modern way of life. The Neolithic spread rapidly across Europe, mainly along the Danube valley and the Mediterranean coastline, reaching the Atlantic coast around 5000-4500 BCE. The existing archaeogenetic data...

Taking a deep look into animals

Advances in neuroscience research and microscopy: a collaborative project driven by researchers of the Max Perutz Labs Vienna, a joint venture of the University of Vienna and the Medical University of Vienna, and the TU Wien (Vienna) allows researchers to look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders.

Towards a climate neutral Europe: The land sector is key

Land use choices can have a significant impact on climate change mitigation and help meet the increased ambition foreseen by the "European Green Deal." It is time to step up efforts to quantify the land sector's carbon emissions and removals. A study, which includes the CMCC Foundation's participation analyzes the EU regulations in force on the subject, which to date still place limits on the...

Can government stimulus programs boost consumer spending?

The world has been experiencing an unprecedented economic downturn due to the COVID-19 pandemic. A significant number of economic activities have shut down, causing contractions in global output, as well as the loss of businesses and family income. Recent evidence shows that millions of people globally lost their jobs and projecting the extent of the impending global economic loss remains a...

A deep dive into better understanding nitrogen impacts

A key atomic building block for all living organisms and one of the most abundant elements in the galaxy, nitrogen is an essential part of our ecosystem. But for our ecosystem to function, nitrogen-based compounds must cycle through air, water, and soil in a delicate balance among the other organic chemical drivers of life.

Researchers develop experimental rapid COVID-19 test using nanoparticle technique

Scientists from the University of Maryland School of Medicine (UMSOM) developed an experimental diagnostic test for COVID-19 that can visually detect the presence of the virus in 10 minutes. It uses a simple assay containing plasmonic gold nanoparticles to detect a color change when the virus is present. The test does not require the use of any advanced laboratory techniques, such as those...
