Decadal growth rate of methane in the atmosphere varied dramatically over the past 30 yeas with three distinct periods of slowed (1988-1998), quasi-stationary (1999-2006) and renewed (2007-2016) phases. An inverse analysis with atmospheric chemistry transport modeling explained these variations consistently. While emissions from oil and gas exploitation and natural climate events caused the slowed growth and the temporary pause, those from coal mining in China and livestock farming in the tropics drove the renewed growth.

Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. This is the conclusion of a study using mice. The results suggest that microglial cells contribute to the negative mood experienced during several neurological diseases, and maybe also depression.

Laser beams can be used to precisely measure an object's position or velocity. Normally, a clear, unobstructed view of this object is required. Irregular environments scatter the light beam - but as it turns out, precisely this effect can be used to obtain optimum information in difficult situations.

To predict when earthquakes are likely to occur, seismologists often use statistics to monitor how clusters of seismic activity evolve over time. However, this approach often fails to anticipate the time and magnitude of large-scale earthquakes, leading to dangerous oversights in current early-warning systems. For decades, studies outside the seismology field have proposed that these major, potentially devastating seismic events are connected to a range of non-seismic phenomena -- which can be observed days or even weeks before these large earthquakes occur. So far, however, this idea hasn't caught on in the wider scientific community.

Nature is full of color. For flowers, displaying color is primarily a means to attract pollinators. Insects use their color vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes.

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers announces the discovery of a new polybutadiene molecule - from a material known for over a century and used to make common products like tires and shoes - that could one day advance this goal through depolymerization.

In a new study an international team of researchers examined three-dimensional digital models of the bones, joints, and muscles of the fins and limbs of two extinct early tetrapods and a closely related fossil fish and discover these early tetrapods had a very distinct pattern of muscle leverage that didn't look like a fish fin or modern tetrapod limbs and their limbs were more adapted for propulsion rather than weight bearing.

It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that certain head-on collisions may in fact clear the galactic nuclei of the matter which would otherwise fuel the black holes contained within.

A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a new study. The research shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy - at least in the equatorial Pacific.

The analysis used ethnographic information from 144 traditional, subsistence-level societies from all over the globe. People were more likely to regard dogs as a type of person if the dogs had a special relationship with women -- such as having names and being treated as family.

Although electric vehicles that reduce greenhouse gas emissions attract many drivers, the lack of confidence in charging services deters others. Building a reliable network of charging stations is difficult in part because it's challenging to aggregate data from independent station operators. But now, researchers have developed an AI that can analyze user reviews of these stations, allowing it to accurately identify places where there are insufficient or out-of-service stations.
