Phys.org / Early respiratory infections may lower higher education completion and adult income
Infants exposed to respiratory illnesses through older siblings typically fare worse in education, income and health in adulthood, according to new research from the University of Copenhagen.
Phys.org / New simulation challenges leading explanation for why galaxies stop forming stars
For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt. Upending this long-held ...
Phys.org / Generating red blood cell-like cells from canine induced pluripotent stem cells
Blood transfusions are crucial in human and veterinary medicine, yet human blood reserves are in constant need of donors, while blood bank systems in veterinary care are nearly nonexistent. This leaves canine transfusions ...
Tech Xplore / Shade-resistant solar cells keep 97% efficiency after 2,000‑hour stress test
It is common for solar panels to be shaded by trees, clouds, birds or buildings. For thin-film solar technologies, however, such shading can cause shaded areas to develop reverse-bias stress (negative voltage), which can ...
Phys.org / Rare sighting reveals Arctic bobtail squid and egg masses in subzero Greenland fjord
Marine biologists have observed the Arctic bobtail squid in its natural habitat in the North Atlantic Ocean for the first time, including the rare discovery of a mature female with eggs. Dr Paige Maroni, from The University ...

The Chinese bahaba (Bahaba taipingensis), a marine fish species endemic to the Chinese coast and known as the "Panda of the Sea," is critically endangered and one of the few marine fish listed as a first-class protected wild ...
Phys.org / Drought, water shortages and crop failures: How does the medieval warm period compare with today?
A heat wave lasting four months, followed by water shortages and crop failures. This is England in the 13th century, not the 21st. What is often called the Medieval Warm Period saw elevated temperatures in many parts of the ...
Phys.org / Samples reveal how Earth slows solar wind striking moon's near side
The moon has been bathed in solar wind for billions of years, but the two hemispheres are struck by solar wind of different speeds and energies.
Medical Xpress / Same carcinogen, different tumors: Mouse study reveals the role of genetic background
Why do cancers develop differently in different people—even when they are exposed to the same risk factors? An international research group, including the German Cancer Research Center (DKFZ), has demonstrated in mice that ...
Phys.org / There's a business case for companies to embrace sustainability, if it's pitched the right way
