Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com) Original source Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall
(via sciencedaily.com) Original source The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts
(via sciencedaily.com) Original source Southern California's iconic sandy coastlines are vanishing at an alarming rate, and it's a warning sign for coastal communities worldwide, new research suggests.
Published Australian study proves 'humans are planet's most frightening predator'
(via sciencedaily.com) Original source A new study demonstrates that kangaroos, wallabies and other Australian marsupials fear humans far more than any other predator.
Published Cement recycling method could help solve one of the world's biggest climate challenges
(via sciencedaily.com) Original source Researchers have developed a method to produce very low emission concrete at scale -- an innovation that could be transformative in the transition to net zero. The method, which the researchers say is 'an absolute miracle', uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete.
Published New AI accurately predicts fly behavior
(via sciencedaily.com) Original source Researchers trained an AI model to accurately predict male fruit flies' courtship behavior in response to any sight of a female. This breakthrough offers new insight into how the brain processes visual data and may someday pave the way for artificial vision technology.
Published Strings that can vibrate forever (kind of)
(via sciencedaily.com) Original source Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes
(via sciencedaily.com) Original source In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
Published Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds
(via sciencedaily.com) Original source A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.
Published Sewage overflows linked to increase in gastrointestinal illnesses
(via sciencedaily.com) Original source A new study has found that residents living in the downstream communities that border the Merrimack River are at a substantially increased risk of developing acute gastrointestinal illnesses (AGI) in the four days following large-volume combined sewer overflows (CSOs).
Published Study finds widespread 'cell cannibalism,' related phenomena across tree of life
(via sciencedaily.com) Original source Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Detecting odors on the edge: Researchers decipher how insects smell more with less
(via sciencedaily.com) Original source While humans feature a sophisticated sense of smell, insects have a much more basic olfactory system. Yet they depend upon smell to survive. Scientists have figured out how fruit flies use a simple but efficient system to recognize odors, and the answer lies at the edges of their antennae.
Published Recycling carbon dioxide into household chemicals
(via sciencedaily.com) Original source Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.
Published Complete stellar collapse: Unusual star system proves that stars can die quietly
(via sciencedaily.com) Original source University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.
Published 3D printing robot creates extreme shock-absorbing shape, with help of AI
(via sciencedaily.com) Original source See how an autonomous robot created a shock-absorbing shape no human ever could -- and what it means for designing safer helmets, packaging, car bumpers, and more.
Published Researchers discover hidden step in dinosaur feather evolution
(via sciencedaily.com) Original source Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.
Published Green infrastructure plans need to consider historical racial inequalities
(via sciencedaily.com) Original source Urban greening projects should consider historical development patterns and past discriminatory practices to avoid exacerbating the unequal distribution of environmental benefits, says an urban and regional planning professor.
Published Warming climate intensifies flash droughts worldwide
(via sciencedaily.com) Original source Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.
