Scientists bring back Earth's 'memory' with mountaintop ice
Good news, everyone: Vine is (probably) coming back. The much beloved wacky short-form-video-sharing app had a short life in the limelight from 2012 to 2017, when it was cut off in its prime (as many would have it). That’s helped ensure that it holds a space in many millennials’ hearts as the last glorious stand of the social web before it became tarnished and commoditized and every app...
Want to save the bees? Pay attention to pathogens and flowers
Humans are fascinated by our planet's distant past. Since human recorded history only goes back a few thousand years, we probe Earth's "memory" in various ways to uncover its secrets. One of these methods is to hunt for traces from the past, also known as "proxies," which help scientists understand what Earth was like long ago.
Cincinnati Zoo shares expertise with Indonesia to save endangered rhinos
New research published in the journal Ecology conclusively shows that certain physical traits of flowers affect the health of bumblebees by modulating the transmission of a harmful pathogen called Crithidia bombi. In particular, the research, conducted by scientists at the University of Massachusetts Amherst, shows that the length of a flower's corolla, or the flower's petals, affects how this...
Mathematicians explain how some fireflies flash in sync
A University of Cincinnati adjunct professor flew to Indonesia this year to visit some old friends, Harapan and Andalas.
Watch an ice sheet melt—and Great Britain and Ireland emerge
Stake out in Pennsylvania's Cook State Forest at the right time of year and you can see one of nature's great light shows: swarms of fireflies that synchronize their flashes like strings of Christmas lights in the dark.

Climate change to produce more rainbows, study finds
Researchers have created the most realistic reconstruction yet of how a vast ice sheet advanced across northwestern Europe starting about 31,000 years ago and then retreated into oblivion, exposing landmasses that today are Great Britain and Ireland. The detailed chronology could improve forecasts of melting ice sheets in Antarctica and Greenland, which could devastate coastal regions...
New research on groundcherries bears new fruits
Climate change will increase opportunities to see rainbows, according to a new study led by researchers at the University of Hawai'i (UH) at Mānoa. The study's authors estimate that by 2100, the average land location on Earth will experience about 5% more days with rainbows than at the beginning of the 21st century.
Partisan divide contributed to false sense of racial equality in pandemic mortality
Over 34 million people in the U.S. don't have enough food. More diverse and adaptable crops are needed to address challenges in food production made worse by climate change. Small, sweet berries called groundcherries may not feed the country, but along with other related "orphan crops," they could strengthen food supplies. Unfortunately, these distant relatives of tomatoes aren't ready for...
New research shows Antarctic summer thaw starts earlier, ends later than previously believed
The early months of the COVID-19 pandemic were marked by far higher death rates among Black people than white people in the United States. Before 2020 ended, however, differences between the two groups had nearly equalized.
Natural nutrient enrichment 8 million years ago caused today's largest ocean 'dead zone'
New research from Colgate University changes our understanding of seasonal thawing in parts of Antarctica, as scientists have learned that summer thawing occurs nearly a month earlier, and stays thawed for a full two months longer than previously believed.
Astronomers spot largest potentially hazardous asteroid detected in last eight years
Oxygen-starved ocean "dead zones," where fish and animals cannot survive, have been expanding in the open ocean and coastal waters for several decades as a result of human agricultural and industrial activity. Trying to predict the scale and location of future dead zones, scientists have looked to the past for historical clues.
Australians less likely to use social media as an information source in a natural disaster
Twilight observations with the US Department of Energy-fabricated Dark Energy Camera at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF's NOIRLab, have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object...
Combination microscopy and DNA analysis reveals new insights into the diet of polar cod
New Charles Darwin University (CDU) research suggest that people are less likely to use social media as an information source during a natural disaster, instead using traditional media and authorities' websites for critical information.
“Why Aren’t We All Bacteria?” Siddhartha Mukherjee Explores the Power of Cells
Polar cod is an important part of the food web of the Arctic. Sarah Maes (KU Leuven) and Fokje Schaafsma (Wageningen Marine Research) investigated the diet of polar cod from the Barents Sea, with the help of colleagues from the KU Leuven and the Alfred Wegener Institute. They did this by combining traditional microscopy with DNA analysis. The study resulted in new insights regarding the diet of...
Study reveals how ancient fish colonized the deep sea
Pulitzer Prize-winning author and doctor Siddhartha Mukherjee on the power of cells and how they shape us
Efficient nanovaccine delivery system boosts cellular immunity
The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive—shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington study, published in Proceedings of the National Academy of Sciences...
California set a record for greenhouse gas reductions in 2020, but it means nothing
Cancer immunotherapies, such as immune checkpoint inhibition therapy, have been attracting attention in recent years as new methods for treating cancer. However, immune checkpoint inhibition therapy is only effective in 20%–30% of cancer patients, so developing better drug delivery systems to induce anticancer cellular immunity is necessary.
A new protocol for light-sheet live imaging of C. elegans adults
First, the good news: The amount of planet-warming gases Californians released into the atmosphere in 2020 was 9% less than the previous year—a record decline mostly because of motorists driving less amid the COVID-19 lockdown.
After years of delays, San Diego's polystyrene foam ban could take effect in April
The beauty of live-imaging studies is the specimen is alive, allowing dynamics such as cell division and embryonic development to be recorded over time.
Examining how first impressions affect later romantic outcomes
Big changes may be coming this spring for many San Diego restaurants and retail stores, because city officials say they plan to follow through on a long-delayed ban on polystyrene foam food containers, coolers, pool toys and similar products.
New push to shore up shrinking Colorado River could reduce water flow to states
A new University of California, Davis, study analyzing romantic first impressions shows that compatibility and popularity among the dating pool are influential in shaping who people pursue as potential romantic partners.
The US may expand speed rules for boaters to protect whales, sparking industry protests
With the Colorado River reservoirs continuing to decline, federal officials announced plans Friday to revise their current rules for dealing with shortages and will pursue a new agreement to achieve larger reductions in water use throughout the Southwest.
A federal effort to expand safety measures to protect endangered right whales from boat collisions in the Atlantic Ocean is receiving a big thumbs down from the maritime industry.
