Politicians in the European Parliament are supportive of post-growth and ecosocialist positions to tackle the climate crisis, and not only green growth. This is the main conclusion of a study carried out by researchers at the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) and the Department of Political and Social Sciences at Pompeu Fabra University (UPF), published this week in the journal Nature Sustainability, which analyzes viewpoints of political elites on degrowth and green growth.
For over 20 years, a research team at Lund University in Sweden has studied the common bluetail damselfly. Females occur in three different colour forms – one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic colour variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.
Researchers at the University of Wisconsin–Madison have identified a protein key to the development of a type of brain cell believed to play a role in disorders like Alzheimer’s and Parkinson’s diseases and used the discovery to grow the neurons from stem cells for the first time.
Microbial communities are thought to contain keystone species, which can disproportionately affect the stability of the communities, even if only present in low abundances. Identifying these keystone species can be challenging, especially in the human gut, since it is not feasible to isolate them through systematic elimination.
We’ve all heard it: Put a frog in boiling water, and it will jump out. But put the same frog in lukewarm water and heat it gradually, and you’ll cook the frog.
Once a favored food of grazing dinosaurs, an ancient lineage of plants called cycads helped sustain these and other prehistoric animals during the Mesozoic Era, starting 252 million years ago, by being plentiful in the forest understory. Today, just a few species of the palm-like plants survive in tropical and subtropical habitats.
In the background of image recognition software that can ID our friends on social media and wildflowers in our yard are neural networks, a type of artificial intelligence inspired by how own our brains process data.
In 1973, physicist Phil Anderson hypothesized that the quantum spin liquid, or QSL, state existed on some triangular lattices, but he lacked the tools to delve deeper. Fifty years later, a team led by researchers associated with the Quantum Science Center headquartered at the Department of Energy’s Oak Ridge National Laboratory has confirmed the presence of QSL behavior in a new material with this structure, KYbSe2.

Researchers from UC San Diego have developed an easily-implemented toolkit for genomics researchers that simplifies the process of analyzing data with deep learning, a type of artificial intelligence capable of improving itself with limited user input.
For decades, the standard reference tool for ultraprecise timekeeping has been the atomic clock. Scientists have known that an even more precise and reliable timepiece was possible, but technical limitations kept it only a theoretical prospect.Now, researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, Texas A&M University and several European institutions are turning theory into practice.
Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough to grasp heavy objects but soft enough to interact safely with humans.

Working laser-powered quantum computers will need a system that can accurately and reliably count and distinguish 50 or more photons every few nanoseconds.
Scientists at St. Jude Children’s Research Hospital showed that a fusion oncoprotein can drive molecularly indistinguishable rhabdomyosarcomas arising from both muscle and blood vessel cells.
Researchers performed complementary experiments showing that inhibiting a specific enzyme in a mouse model protects the dopamine-producing neurons that are normally lost as Parkinson's disease progresses, effectively halting the progression of the disease. The findings open the door to the development of novel therapeutics targeting the enzyme that may slow or prevent the progression of Parkinson's disease in people—a major unmet need.
Susanna Stroik, PhD, and Dale Ramsden, PhD, in the Department of Biochemistry and Biophysics at the UNC School of Medicine, have learned more about an enzyme found to be overly expressed in patients with hereditary breast cancer, ovarian cancer, and prostate cancer.
New research appearing today in the journal Nature shows that a cocktail of drugs already approved to treat high blood pressure quickly reduces brain swelling and improves outcomes in animal models of brain injury.
One University of Kentucky researcher has helped solve a 60-year-old mystery about one of the body’s most vital organs: The heart. The research team has microscopically mapped out part of the heart. To put this microscopic level into perspective, if the heart is a continent, UK's Kenneth S. Campbell and fellow researchers are looking at single strands of hair.
A new analysis shows where and how industrial agriculture is most sensitive to disruptions
An international team has for the first time researched the longevity of neutralizing antibodies in HIV-1-infected people. Currently, it is assumed that an HIV-1 vaccine can only be effective if it produces these antibodies in vaccinated humans.
Glaucoma remains one of the most common causes of vision loss and blindness in the U.S. and much of the world, disproportionately affecting older people, African Americans, and Hispanics and Latinos.
One University of Kentucky researcher has helped solve a 60-year-old mystery about one of the body’s most vital organs: The heart. Kenneth S. Campbell, Ph.D., the director of translational research in the Division of Cardiovascular Medicine in the UK College of Medicine, helped map out an important part of the heart on a molecular level. The study titled “Cryo-EM structure of the human cardiac myosin filament” was published online in the prestigious journal Nature earlier this month.

An international research team at DTU has increased the shelf life of electrolyzers that convert CO2 from half a day to 100 hours. This is good news for companies working with the process. The findings were recently published in Nature Catalysis
Far from being stiff and pointy, a coronavirus’s infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A tiny hinge makes that bendiness possible, and scientists say disabling that hinge could be a good way to thwart infection.
A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA—loops of DNA found outside of regular chromosomes—are twice as likely to relapse and three times as likely to die within five years of diagnosis.
