Human composting: California clears the way for greener burial method

State is the fifth to legalize environmentally friendly process that allows for natural reduction of human remains to soilCalifornia lawmakers have approved a new way of returning those who have died to the earth, after Gavin Newsom signed into law a bill allowing human composting on Sunday.Cremation, which accounts for more than half of burials, is an energy-intensive process that emits...

U.S. math professor gets probation, not prison, in China Initiative case

An applied math professor at Southern Illinois University (SIU), Carbondale, was sentenced today to 1 year of probation—and no prison time—after being found guilty earlier this year of filing incorrect tax returns and failing to report a foreign bank account. Mathematician Mingqing Xiao was prosecuted under a controversial U.S. law enforcement effort launched in 2018, called...

Why you should pay attention to fly vomit

New research from the University of Massachusetts Amherst concerning "synanthropic" flies—or the non-biting flies that live with us—argues that we need to pay far more attention to them as disease carriers. While epidemiologists have focused their attention on the biting flies that can spread diseases by transferring infected blood from host to host, it turns out that what the non-biting flies...

Elusive atmospheric wave detected during Tonga volcanic eruption

The catastrophic eruption of the Hunga Tonga–Hunga Haʻapai volcano in 2022 triggered a special atmospheric wave that has eluded detection for the past 85 years. Researchers from the University of Hawaiʻi at Mānoa, Japan Agency for Marine–Earth Science and Technology (JAMSTEC), and Kyoto University relied on state-of-the-art observational data and computer simulations to discover the...

Research team creates new magnetic quasiparticle

From The City College of New York's Center for Discovery and Innovation and the Physics Department comes news of a new type of magnetic quasiparticle created by coupling light to a stack of ultrathin two-dimensional magnets. This achievement sprouting from a collaboration with the University of Texas at Austin lays the foundation for an emergent strategy to artificially design materials by...

Research team looks to past for insights on future of megafauna

Are elephants important? How about rhinoceros? Or lions? What happens if Earth loses its last remaining large animals? New research by Professor of Biology Felisa Smith at the University of New Mexico shows the profound impacts of losing large-bodied mammals, or megafauna, in ecosystems.

A better understanding of crop yields under climate change

Researchers use satellites to measure soil moisture around certain crops to solve a long-standing mystery about how water impacts agricultural production. The researchers found that models using soil moisture explain 30% to 120% more of the year-to-year variation in yield across crops than models that rely on rainfall. The research give scientists a better understanding of how crop yields will...

A better understanding of crop yields under climate change

You don't need a Ph.D. in agriculture to know that water is critical to crop production. But for years, people like Jonathan Proctor, who has a Ph.D. in Agriculture and Resource Economics from the University of California Berkeley, have been trying to explain why the importance of water isn't showing up in statistical models of crop yield.

How many ants are there on Earth?

How many stars are there in our galaxy? How many grains of sand in the Sahara? How many ants live on Earth? These are all questions that seem impossible to answer. However, through intensive and extensive data analysis, science is coming amazingly close to finding the solutions. When it comes to ants, a team led by Würzburg biologists Sabine Nooten and Patrick Schultheiss has done just that.

Amino acid supplement is a key to reproductive health in dairy cows

Lysine is an essential amino acid for dairy cows, helping boost milk production when added to the diet at adequate levels. But could lysine benefit cows in other ways? A new University of Illinois study shows rumen-protected lysine can improve uterine health if fed during the transition period. The study, "Effect of feeding rumen-protected lysine through the transition period on postpartum uterine...

Researchers create new magnetic quasiparticle

A new type of magnetic quasiparticle has been created by coupling light to a stack of ultrathin two-dimensional magnets. This achievement lays the foundation for an emergent strategy to artificially design materials by ensuring their strong interaction with light.

Undergrad publishes theory on immune dysfunction in space

It's been known for decades that though astronauts' immune systems become suppressed in space, leaving them vulnerable to disease, the exact mechanisms of immune dysfunction have remained a mystery. Now a Cornell undergraduate has found a potential solution.

Researchers transplant the RNA editing machine of moss into human cells

If everything is to run smoothly in living cells, the genetic information must be correct. But unfortunately, errors in the DNA accumulate over time due to mutations. Land plants have developed a peculiar correction mode: They do not directly improve the errors in the genome, but rather elaborately in each individual transcript. Researchers at the University of Bonn have transplanted this...

Wildfire smoke may have amplified Arctic phytoplankton bloom

Smoke from a Siberian wildfire may have transported enough nitrogen to parts of the Arctic Ocean to amplify a phytoplankton bloom, according to new research from North Carolina State University and the International Research Laboratory Takuvik (CNRS/Laval University) in Canada. The work, which appears in Communications Earth & Environment, sheds light on some potential ecological effects from...

Researcher helps identify new evidence for habitability in ocean of Saturn's moon Enceladus

The search for extraterrestrial life has just become more interesting as a team of scientists, including Southwest Research Institute's Dr. Christopher Glein, has discovered new evidence for a key building block for life in the subsurface ocean of Saturn's moon Enceladus. New modeling indicates that Enceladus's ocean should be relatively rich in dissolved phosphorus, an essential ingredient for...
