Cities across the country have sought ways to improve neighborhood safety and in recent years have pointed to demolishing abandoned housing as a way to achieve the goal. While millions of dollars have been spent on the efforts, a recent University of Kansas study found a program demolishing more than 500 abandoned residential properties in Kansas City, Missouri, did not significantly reduce nearby...
Even with decades of unprecedented development in computational power, the human brain still holds many advantages over modern computing technologies. Our brains are extremely efficient for many cognitive tasks and do not separate memory and computing, unlike standard computer chips.
In a story of lost and stolen books and scrupulous detective work across continents, a Caltech historian and his former student have unearthed previously uncounted copies of Isaac Newton's groundbreaking science book Philosophiae Naturalis Principia Mathematica, known more colloquially as the Principia. The new census more than doubles the number of known copies of the famous first edition,...
Scientists have shown that the size and makeup of groups of social birds can predict how efficiently they use and move through their habitat, according to new findings published today in eLife.
According to a new Finnish study, different groups of insectivores compete for the same type of food. Researchers of the University of Turku, Finland, and the Finnish Museum of Natural History made a discovery by comparing birds, bats and dragonflies that forage in the same area in Southwest Finland. These very distantly related predators consumed the same insect groups, such as flies, mosquitoes,...
The universe is getting hotter, a new study has found.
Researchers have discovered a new "hidden" gene in SARS-CoV-2—the virus that causes COVID-19—that may have contributed to its unique biology and pandemic potential. In a virus that only has about 15 genes in total, knowing more about this and other overlapping genes—or "genes within genes"—could have a significant impact on how we combat the virus. The new gene is described today in the...
A team at Aalto University has used bacteria to produce intricately designed three-dimensional objects made of nanocellulose. With their technique, the researchers are able to guide the growth of bacterial colonies through the use of strongly water repellent—or superhydrophobic—surfaces. The objects show tremendous potential for medical use, including supporting tissue regeneration or as...
A new study lead by GSI scientists and international colleagues investigates black-hole formation in neutron star mergers. Computer simulations show that the properties of dense nuclear matter play a crucial role, which directly links the astrophysical merger event to heavy-ion collision experiments at GSI and FAIR. These properties will be studied more precisely at the future FAIR facility. The...
NASA released an independent review report Tuesday indicating the agency is well positioned for its Mars Sample Return (MSR) campaign to bring pristine samples from Mars to Earth for scientific study.
