A systematic search for copies of the first edition of Newton's Principia (1687) unearthed copies in at least 27 countries, yielding new insights about how people engaged with the famous book.
Forget glue, screws, heat or other traditional bonding methods. Engineers have now developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed.
A first of its kind assessment of coral reefs in U.S. waters is again sounding the alarm over the continued decline of these sensitive underwater ecosystems, which scientists deem essential to the health of the world's oceans amid the environmental effects posed by human activity and climate change. The report, released Tuesday by the National Oceanic and Atmospheric Administration and the...
Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3-D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed.
Climate change is fueling record-breaking fires, hurricanes and floods. Global emissions of greenhouse gases are returning to pre-pandemic levels. And America—which has emitted more planet-warming gases than any other nation—has just become the only country to quit the Paris climate agreement.
Scientists have developed an optical elastography technique that could revolutionize the accuracy and ease to which health professionals can detect biomechanical alterations of cells and tissues.
New research by LSU sociologists indicate it wasn't Christian nationalism that drove churchgoers' Trump vote in 2016. Rather, surprisingly, Christian nationalism was important among non-churchgoers. Christian nationalism is thought to have been an important factor in the election of Donald Trump as President of the United States in 2016—and likely drove many of his supporters to the polls in...
Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster than the radio waves we currently rely on. A new research project, supported by the National Geospatial-Intelligence Agency, proposes to use the properties of light itself to...
Just when you thought it should be safe to go back to the water, the record-setting tropics are going crazy. Again.
A new study conducted at the University of New South Wales and published in the November/December 2020 issue of Physiological and Biochemical Zoology sheds light on a possible connection between an animal's environmental conditions and the traits of its offspring. The study, Maternal Temperature, Corticosterone, and Body Condition as Mediators of Maternal Effects in Jacky Dragons (Amphibolurus...
A new mobile app allows people to explore how global warming will affect the future climate of their towns and cities.
For a geoscientist, the benefits of performing fieldwork are countless. Researching in nature gives geoscientists firsthand contact with the earth's raw materials and a chance to test ideas and develop theories—as well as to make new discoveries. For this reason, geoscientists often trek to faraway locations, negotiating difficult physical terrain and distinctive cultural landscapes to access...
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. The agency established the MSR Independent Review Board (IRB) to evaluate its early concepts for a groundbreaking, international partnership with ESA (European Space Agency) to return the first...
Researchers have identified a gene signature in localized prostate cancer that predicts the cancer's odds of spreading and its response to a common treatment for advanced disease.
A molecular regulator made of analog signals is found to regulate electrical signals in the brain.
A new model shows how brine on Jupiter's moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings, which are important for the upcoming Europa Clipper mission, may explain cryovolcanic eruptions across icy bodies in the solar system.
