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 powerful future insights about the nature of our universe.

A bounty of 10 African penguin chicks has hatched in just over a year at a San Francisco science museum as part of an effort to conserve the endangered bird.

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.

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.

It has long been established that changing an environment can reduce crime. For example, increased light in an area has the potential to discourage would-be offenders by making them more visible.

Recent studies have shown a strong correlation between responses to plant density and low light, indicating that the scarcity of light is often a limiting factor in high-density crop communities.

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 compounds that could impact indoor air quality than previously thought.

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 Center, and the University of New South Wales.

Since the Green Revolution in the 1960s, intensive agricultural production practices have laid the foundation for food security. However, these measures are also accompanied by significant resource input and environmental impacts. Meeting the increasing food demand in a sustainable manner becomes a global challenge.

In a study published in the journal Science China Earth Sciences, a research team conducted joint observations of ecosystem oxygen production and carbon sinks and near-surface atmospheric oxygen concentrations on the Qinghai-Tibetan Plateau and meteorological elements at Beijing Fangshan Station from 2018 to 2020.

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.

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.

PFAS have earned the name "forever chemicals" with good reason—the man-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
