What’s at stake for science in Supreme Court’s ‘abortion pill’ case?

Next month, the U.S. Supreme Court (SCOTUS) will hear oral arguments in a case that could have profound implications for the authority of the Food and Drug Administration (FDA)—and that will certainly affect access to abortion. The case, which involves disputes over the safety of the FDA-approved abortion drug mifepristone, is an appeal of two lower court decisions that agreed with a...

Results from South Pole Telescope's new camera emerge

For more than five years, scientists at the South Pole Telescope in Antarctica have been observing the sky with an upgraded camera. The extended gaze toward the cosmos is picking up remnant light from the universe's early formation. Now researchers have analyzed an initial batch of data, publishing details in the journal Physical Review D. The results from this limited dataset hint at even more...

Why politics brings out the worst in us

Tap into any social media platform, turn on the television or cue up a podcast, and it is easy to find examples of hypocrisy or bad behavior in political discourse, and new research from University of Nebraska–Lincoln political scientists may explain why.

NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep Space Network (DSN), which communicate with spacecraft via radio waves, to be retrofitted for optical or laser communications.

Cleaned surfaces may be germ-free, but they're not bare

Since the outbreak of COVID-19, surfaces in public spaces have been cleaned more often. While disinfectant solutions eliminate germs, they don't leave behind a truly bare surface. They deposit a thin film that doesn't get wiped up, even after giving the surface a good polish. Researchers reporting in ACS ES&T Air show that residues left by commercial cleaning products contain a wider range of...

Tropical cyclone genesis projected to move toward the poles

In a recent study published in Geophysical Research Letters, researchers unveil a poleward shift of tropical cyclone (TC) genesis on a global scale as a result of climate change. Led by Dr. Xi Cao from the Institute of Atmospheric Physics, the research team collaborated with experts from institutions including the University of Tokyo, Zhejiang University, Yunnan University, the National Climate...

Uncovering the green miracle of urbanization

Between 1990 and 2005, the national average urban fractional vegetation cover (FVC) decreased from 0.38 to 0.35 due to the increase in floor area ratio and impervious surface in urban areas. The decline is particularly pronounced in megacities, small, medium and small cities.

An eight-phase methodology for analyzing microplastics in soil ecosystem

In today's world, plastics are used extensively due to their favorable properties and affordable costs. The widespread use of these non-biodegradable materials, however, makes them a waste management nuisance and global environmental concern. It is estimated that by 2050, approximately 12 billion metric tons of plastic waste will be dumped into landfills.

Politically conservative CEOs found to think differently about transparency

As a purely voluntary form of disclosure, management earnings forecasts may tell us as much about the managers themselves as about their company's financial future. All sorts of personality traits may influence the content and cadence of forecasts, but you would expect core attributes—such as political ideology, which has been likened to an "official religion" in the United States—to be the...

10 years preparing for 'Armageddon'

It's a scenario made famous by the 1998 film "Armageddon": an asteroid is spotted on a collision course with Earth, and experts scramble to plan a space mission to rendezvous with the asteroid and mitigate the danger. It's classic science fiction, but did you know there is a very real group responsible for recommending such a response in real life? And it celebrates its tenth birthday this week.

Temperatures are rising, but soil is getting wetter—why?

Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide, and perhaps most importantly, how productive our food systems are. As temperatures rise due to human-caused climate change, some researchers are concerned that soils will dry. However, between 2011 to 2020, soil moisture increased across 57% of the United States during summer, the warmest time of...
