The weather in Hateruma island is frequently influenced by the northwest monsoon traveling over China, which carries the emission signals of air pollutants. The observed ratios of CO2 and CH4 variabilities showed a significant decrease

Utilizing a 'krafty' waste product: Toward enhancing vehicle fuel economy
Given concerns over global climate warming, researchers are hard at work on minimizing the amount of fuel that we all use in everyday life. Reducing the weight of vehicles will lessen the amount of fuel required to power them, and put money back into your pocket.

Scientists define binary tropical cyclones
In the Northwest Pacific, most tropical cyclones occur alone during their lifetime. However, sometimes two or several tropical cyclones exist simultaneously. Generally, two tropical cyclones occurring simultaneously are referred to as binary tropical cyclones (BTCs), and they concurrently perform a mutual counterclockwise spin and move closer to each other when at a relatively close range. This ph

Noise reduction via intermittent control by utilizing a plasma actuator
A research team in the Department of Mechanical Engineering at Toyohashi University of Technology developed a method for reducing aerodynamic noise via plasma. Cavity flow, such as the flow around car gaps of high-speed trains, often radiates aerodynamic noise. A plasma actuator inducing flow was applied to suppress this noise. By periodically switching off the power of the plasma actuator, a high

Starship Test Flight to 50,000 Feet Could Happen as Soon as Next Week
It's a Date According to local road closure filings , SpaceX is getting ready for its next big test flight: Starship's first high-altitude flight, to 50,000 feet (roughly 9.5 miles), at its testing facility in Boca Chica, Texas. The filings, published on Wednesday, say that SpaceX is looking at a time window on November 9, from 9 am to 9 pm. The listed purpose is a second static fire test of the

Gray wolves are leaving the endangered species list. But should they?
Wolves continue to be a contentious issue. (Pexels/) Last week, the Trump administration announced its plan to remove the gray wolf from the endangered species list after it's "successful" recovery. In a press release, Secretary of the Interior David Bernhardt stated that "the gray wolf has exceeded all conservation goals for recovery." But biologists argue that the decision is premature, and wou

Strain of rhizobacteria shown to naturally and sustainably promote rice growth
Large amounts of chemical fertilizers can lead to severe environmental pollution. Biofertilizers are a preferred and sustainable alternative technology that can promote plant health without damaging ecological impacts. Plant growth-promoting rhizobacteria (PGPRs) can be used as biofertilizers and reduce the use of chemical fertilizers and pesticides while also ensuring sustainable and increased pr

Research reveals infertile spikelets contribute to yield in sorghum and related grasses
Much of the food we eat comes from grasses such as rice, wheat, corn, sorghum, and sugarcane. These crops still resemble the wild species from which they were derived. In all grasses the structures that contain the flowers and seeds are called spikelets. In the tribe Andropogoneae, a major group of grasses that cover 17 percent of the earth's surface, the spikelets come in pairs, one of which bear

When new males take over, these female primates hurry up and mature
Most mammals—including humans and other primates—reach sexual maturity early or late depending on lots of different factors, such as how much food there is to eat. Now, researchers studying close primate relatives of baboons known as geladas have shown for the first time that females of this species suddenly hurry up and mature when a new male enters the picture. Their findings are reported in the

Population dynamics and the rise of empires in Inner Asia
In a new study published in Cell, researchers explored the genetic, sociopolitical and cultural changes surrounding the formation of the eastern Eurasian Steppe's historic empires. The study analyzed genome-wide data for 214 ancient individuals spanning 6,000 years and discusses the genetic and cultural changes that preceded the rise of the Xiongnu and Mongol nomadic pastoralist empires.

From hard to soft: Making sponges from mussel shells
Scientists have discovered a spongy form of calcium carbonate (CaCO3), a material found in limestone, chalk, marble, and the shells of mussels and other shellfish. While most forms of calcium carbonate are hard minerals, this new form is soft and absorbent. The researchers, reporting November 5 in the journal Matter, made the discovery while exploring new uses for leftover mussel shells.

Light pollution at night severely disrupts the reproductive cycle of corals
Studying the reproductive cycle of two coral species from the Indo-Pacific Ocean over the course of three months, researchers found that light pollution caused delayed gametogenesis and unsynchronized gamete release. To shed light on the findings, they created a first-of-its-kind global map that highlights areas in the world most threatened by nighttime artificial light. This light pollution impac
