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.

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.

For the first time, researchers have attributed an understudied adverse fetal outcome to the strenuousness of an expectant mother's job.

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth's magnetic field protects the planet from solar...

The more TV kids watch, the more ads they see and the more likely they are to ask for things on shopping trips. That may contribute to parents' overall stress levels, researchers found.

Using the Nobel Prize gene-editing technique, a researcher has found that two genes regulate social dominance in cichlid fish and - possibly - humans.

A study compared crime rates near abandoned houses that were demolished and similar properties that were not, finding no reduction in violent or property crime near those torn down. Findings suggest simply demolishing dangerous houses is not enough to reduce crime.

Researchers have explored all COVID-19 research published during the initial phase of the pandemic. The results, which were achieved by using a machine learning-based approach, will make it easier to direct future research to where it is most needed.

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.

A new synthetic protein nanoparticle capable of slipping past the nearly impermeable blood-brain barrier in mice could deliver cancer-killing drugs directly to malignant brain tumors, new research shows.

While immunotherapies work well for some cancers, others are immune-resistant and condemn patients to the severe side effects of long-term chemo treatment. A new cancer vaccine successfully treated immune-resistant breast cancer in mice, 100% of which survived a second injection of cancer cells, indicating long-term immunity with no side effects.

Researchers have devised a system for decontaminating N95 masks using off-the-shelf materials that can be purchased at a hardware store, combined with ultraviolet type C (UV-C) lights found in academic research and industrial facilities.

Brain-computer interface (BCI) technologies are no longer hypothetical, yet there are fundamental aspects of the technology that remain unaddressed by both ethicists and policy-makers.

When the San Francisco Bay Area mandated shelter-in-place March 16, it created a natural experiment for UC Berkeley's Ron Cohen, who had established an inexpensive pollution sensor network in local neighborhoods. The sensors showed carbon dioxide emissions plummeting 25 percent in the subsequent six weeks, mostly because of a 48 percent drop in traffic. Networks like this -- soon to be emplaced in...

For adults, the goal of exercise is often to shed some pounds, but new research suggests the objective should be different for kids.

Diversifying agricultural systems beyond a narrow selection of crops leads to a range of ecosystem improvements while also maintaining or improving yields, according to a new study that analyzed thousands of previously conducted experiments. Diversification practices such as crop rotations and planting prairie strips can lead to 'win-win' results that protect the environment without sacrificing...

A new study 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.

Using high-speed video and schlieren imaging, a research engineer has created videos that show how air flows through masks with and without exhalation valves.

A study of how 98 million Americans move around each day suggests that most infections occur at 'superspreader' sites, and details how mobility patterns help drive higher infection rates among minority and low-income populations.

Groups of animals consider multiple factors before deciding whether to fight rivals, researchers say.

Bioengineers have used organoids - tiny lab-grown organs - to mimic the early development of the heart in the mouse embryo. The work is another step towards future bioartificial organs for research and transplants.
