New research in Science is showing how the rise of modern agriculture has turned a North American native plant, common waterhemp, into a problematic agricultural weed.

Rising ocean temperatures are driving deterioration of kelp forests worldwide, but a University of Otago study hopes to help turn the tide and restore the valuable habitats.

Electric cars – and their continued sales growth – are expected to have a greener, cleaner influence on air pollution and reduce human mortality in most, if not all, U.S. metropolitan areas, according to Cornell research published in Renewable and Sustainable Energy Reviews (March 2023).

As with many natural phenomena, scientists look to past climate to understand what may lie ahead as Earth warms. 

Invasive species of plants have a knack for settling in new settings and making big changes to an ecosystem, even leading to extinctions of native species.

The researchers say that one possible explanation for this residual glow is that our inner solar system contains a tenuous sphere of dust from comets that are falling into the solar system from all directions, and that the glow is sunlight reflecting off this dust.

In December 2022, Earth was in the grips of La Niña—an oceanic phenomenon characterized by the presence of cooler than normal sea-surface temperatures in the central and eastern tropical Pacific.

Dust briefly clouded the skies over Sicily in early December 2022, yet the Italian island’s iconic volcano still managed to put on a show.

Sand lance are small schooling fish impressively rich in lipids, which makes them a fantastic and significant food source for at least 70 different species ranging from whales and sharks to seabirds, says UConn Associate Professor of Marine Sciences Hannes Baumann.

A research group from Nagoya University in Japan has developed a model to clarify the importance of analyzing the formation of clouds from human and natural particles.
