How we measure biodiversity can have profound impacts on land-use
A study led by Princeton University illustrates this challenge by using several different approaches to solve the same puzzle: Given a target amount of food, where should new croplands be put to minimize environmental or biodiversity impacts?

Using the ancient art of Kirigami to make an eyeball-like camera
Using Kirigami, the Japanese art of paper cutting, a mechanical engineer at the University of Houston has developed a camera with a curvy, adaptable imaging sensor that could improve image quality in endoscopes, night-vision goggles, artificial compound eyes and fish-eye cameras.

COVID-19 vaccine generates immune structures critical for lasting immunity
A new study from researchers at Washington University School of Medicine in St. Louis, published June 28 in the journal Nature, has found evidence that the immune response to Pfizer's mRNA vaccine against COVID-19 is both strong and potentially long-lasting.

'Unexciting' an anxious brain: Novel drug reduces anxiety-like behavior in mice
Anxiety is considered a natural response to stress. However, a state of heightened anxiety, called anxiety disorder, prevents thousands of people from living their best lives. While several underlying mechanisms have been therapeutically targeted, much remains to be discovered about this disorder. In an effort to get closer to unravelling the mechanisms that govern this condition, Japanese researchers have identified a drug that reduces glutamate-induced neurotransmission, involved in anxiety-like behavior.

Mouse brain imaged from the microscopic to the macroscopic level
Researchers at the University of Chicago and the U.S. Department of Energy's (DOE) Argonne National Laboratory have leveraged existing advanced X-ray microscopy techniques to bridge the gap between MRI (magnetic resonance imaging) and electron microscopy imaging, providing a viable pipeline for multiscale whole brain imaging within the same brain.

CHOP researchers discover unique immune response by cells critical to lung health
CHOP researchers have discovered that a specific type of lung cell exhibits unconventional immune properties and may contribute to the outcome of respiratory viral infections. They found that AT2 cells express high levels of major histocompatibility complex II (MHC-II), an important immune system trigger, and that AT2 MHC-II expression appears to confer an appreciable advantage in the outcome of respiratory viral infection.

Are we missing other earths?
Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds.

Weird warbler reveals genetics of its mismatched colors
An incredibly rare hybrid warbler with mismatched color patterns has allowed researchers to disentangle the genetic drivers of two traits that usually come as a package deal--the black face mask and the black throat patch in blue-winged and golden-winged warblers.

Pediatricians ID cause of muscle breakdown in rare disease found on newborn screening
It was a nagging mystery: A rare disease expert at UPMC Children's Hospital had found a successful treatment for two of the deadliest symptoms of one of the more common classes of rare diseases diagnosed by newborn screenings, but one symptom -- painful episodes of muscle breakdown that land victims in intensive care -- persisted. Today, the scientists announce that they've gotten to the bottom of the self-destructive syndrome and have a good lead on a treatment.

Unique exoplanet photobombs Cheops study of nearby star system
While exploring two exoplanets in a bright nearby star system, ESA's exoplanet-hunting Cheops satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet 'with no known equivalent,' say the researchers.

US presidents' narcissism linked to international conflict
The most narcissistic US presidents since 1897 preferred to instigate conflicts with other great power countries without seeking support from allies, a new study suggests.Results showed that of the presidents measured, those highest in narcissism -- including Lyndon B. Johnson, Teddy Roosevelt and Richard Nixon -- were about six times more likely to initiate a dispute with another great power in any given year than a president with average levels of narcissism.
