Income inequality and carbon dioxide emissions have a complex relationship
Income inequality and carbon dioxide emissions for high-income nations such as the United States, Denmark and Canada are intrinsically linked—but a new study from Drexel University has taken a deeper look at the connection and found this relationship is less fixed, can change
Pesticides impair mobility and immune system of Brazilian native stingless bees, study shows
A study conducted by Brazilian researchers affiliated with São Paulo State University (UNESP), the Federal University of São Carlos (UFSCar) and the Federal University of Viçosa (UFV) has shown how three pesticides widely used by farmers in Brazil—imidacloprid, pyraclostrobin
Study suggests disproportionate number of the most innovative CEOs hail from US counties with a frontier history
Biographies of Jeff Bezos don't make much of Albuquerque, New Mexico. Although the founder and executive chairman of Amazon lived there from birth until his teenage years, the Duke City is mainly treated as a humble backdrop for Bezos's early exploits as a budding entrepreneur
Feeling rough after your COVID shot? Congrats, it's working!
One of the most common reasons for bypassing the COVID vaccine is concern about side effects like tiredness, muscle and joint pain, chills, headache, fever, nausea and feeling generally unwell. But a new study has found that the symptoms indicate a robust immune response that
Lone Star State: Tracking a low-mass star as it speeds across the Milky Way
Astronomers have discovered a rare hypervelocity L subdwarf star racing through the Milky Way. More remarkably, this star may be on a trajectory that causes it to leave the Milky Way altogether.
NASA's Webb opens new window on supernova science
Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the
Unregulated sales of a toxic and hallucinogenic mushroom endanger public health
Americans' interest in a potentially harmful 'magic mushroom' is soaring, according to a new study. The scientists suggest that the growing market for Amanita muscaria may be sparked in part by emerging clinical research supporting the safety and efficacy of psilocybin as a
Case studies show how quasi-governmental organizations could strengthen climate adaptation governance
The politicization of climate issues and the unsynchronized efforts of stakeholders are hindering the effectiveness of climate adaptation governance in the U.S. According to a new study the design characteristics of quasi-governmental organizations (QGOs) could provide insights
Brain's structure hangs in 'a delicate balance'
Researchers examined anatomy of neurons from humans, mice and fruit flies. They discovered that the cellular structure of the brain is at a critical point, poised between two phases. New insights could help design computational models of the brain's complexity.
Protein study could help researchers develop new antibiotics
A team has found a way to make the bacterial enzyme histidine kinase water-soluble, which could make it possible to rapidly screen potential antibiotics that might interfere with its functions.
Study reveals target for reversing scar tissue after heart attack
New research discovers a potential path to prevent permanent scarring and heart failure following a myocardial infarction.
Researchers engineer new approach for controlling thermal emission
If a material absorbs light, it will heat up. That heat must go somewhere, and the ability to control where and how much heat is emitted can protect or even hide such devices as satellites. An international team of researchers has published a novel method for controlling this
Novel radiotracer produces high quality images of 'Alzheimer's disease of the heart'
A newly developed radiotracer can generate high quality and readily interpretable images of cardiac amyloidosis, a condition referred to as the 'Alzheimer's disease of the heart.' As the first amyloid-specific and pan-amyloid binding radiotracer designed for planar and SPECT/CT
Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments
Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who
Fine-tuning leaf angle with CRISPR improves sugarcane yield
A CABBI research team has used CRISPR/Cas9 gene editing to optimize leaf angle in sugarcane, increasing the amount of sunlight it captures and the amount of biomass it produces.
Early life exposure to weed pollen could increase childhood asthma risk
A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive
Two can play that game: juvenile dolphins who play together are more successful as adults
Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Protocol for creating 'wired miniature brains'
Researchers have developed -- and shared -- a process for creating brain cortical organoids -- essentially miniature artificial brains with functioning neural networks.
Advanced AI-based techniques scale-up solving complex combinatorial optimization problems
A framework based on advanced AI techniques can solve complex, computationally intensive problems faster and in a more more scalable way than state-of-the-art methods, according to a new study.
Study shows first evidence of male-female differences in how pain can be produced
Research suggests that males and females differ in their experience of pain, but up until now, no one knew why.
Hubble finds surprises around a star that erupted 40 years ago
Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst
Researchers demonstrate the first chip-based 3D printer
Researchers have demonstrated the first chip-based 3D printer, a tiny device that emits reconfigurable beams of visible light into a well of resin that rapidly cures into a solid shape. The advance could enable a 3D printer small enough to fit in the palm of a person's hand.
NASA watches Mars light up during epic solar storm
In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet.
Shortage of skilled plant breeders could impact global food security
A lack of scientists specialized in plant breeding could lead to 'dire' food security implications in Australia, and around the world, according to new research conducted across three continents.
Splitting hairs: Research team applies science of biomechanics to understand our bad hair days
Academics are often accused of "splitting hairs," but a team at Trinity College Dublin has now devised a machine to do just that. We all have a bad hair day from time to time, and split ends are a common problem. However, the science behind this kind of hair damage is poorly
