In search for alien life, purple may be the new green
From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth, where conditions favored the evolution of organisms that perform oxygen-producing photosynthesis using the green pigment chlorophyll a.
Physicists explain, and eliminate, unknown force dragging against water droplets on superhydrophobic surfaces
Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it's commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics of how water droplets behave.
Creating an island paradise in a fusion reactor
In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have shown how two old methods can be
Study quantifies ecological restoration effectiveness on greenhouse gas emissions
Increasing atmospheric concentrations of greenhouse gases (GHGs) are having irreversible consequences for the future of the Earth. However, the general pattern of the impacts of ecological restoration on the three major GHGs on a global scale has not yet been analyzed.
Researchers create new AI pipeline for identifying molecular interactions
Understanding how proteins interact with each other is crucial for developing new treatments and understanding diseases. Thanks to computational advances, a team of researchers led by Assistant Professor of Chemistry Alberto Perez have developed an algorithm to identify these
Scientists develop nanosilver-impregnated silk suture against surgical site infection
In recent years, the adherence of microorganisms to surfaces or coatings has created major health risks to humans. Among these, microbial attachment and growth on surgical suture lines accounts for more than 20% of health-related infections in patients.
New study sheds light on the structure and evolution of an enzyme in psychoactive fungi
An international research team has investigated the biosynthesis of psilocybin, the main ingredient of hallucinogenic mushrooms. They gained new insights into the structure and reaction mechanism of the enzyme PsiM. It plays a key role in the production of psilocybin. The
A universal path for converting light into current in solids
Researchers have long wondered whether light can be efficiently converted into electricity. Realistic and efficient methods to generate electricity from light, photocurrent, has numerous potential applications in the clean conversion of energy, information processing, sensors,
Deadly bacteria show thirst for human blood: Research outlines the phenomenon of bacterial vampirism
Some of the world's deadliest bacteria seek out and feed on human blood, a newly-discovered phenomenon researchers are calling "bacterial vampirism."
Exploring the interactions between baby marmosets and their caregivers
The connection that infants form with their parents or caregivers is crucial for their cognitive, social, and emotional development. These attachments vary in quality, depending on how caregivers respond to the infant's needs. When caregivers are attentive, infants are likely
Electrical control of magnetism by electric field and current-induced torques
In a review article published in Reviews of Modern Physics, Fèlix Casanova from the Nanodevices group at CIC nanoGUNE, Prof. Albert Fert, Nobel Prize in Physics, and his colleagues review the state of the art of electrical control of magnetism and give scientific and
Pleasure or Pain? He Maps the Neural Circuits That Decide.
The work of the neuroscientist Ishmail Abdus-Saboor has opened up a world of insights into precisely how much pleasure and pain animals experience during different forms of touch. The post Pleasure or Pain? He Maps the Neural Circuits That Decide. first appeared on Quanta
CMS collaboration releases Higgs boson discovery data to the public
As part of its continued commitment to making its science fully open, the CMS collaboration has just publicly released the combination of CMS measurements that contributed to establishing the discovery of the Higgs boson in 2012.
How phytochemical diversity affects plant adaptation to stress
Phytochemical diversity plays a critical role in determining plant adaptation and fitness, as well as ecosystem functions and services. However, phytochemicals and their ecological adaptations have long been ignored. Fine (or absorptive) roots, microorganisms, and soil form the
New time-resolved ultraviolet photodissociation mass spectrometry strategy for target protein stability analysis
How mutations impact protein stability and structure dynamics is crucial for understanding the molecular mechanism of the disease and the targeted drug design. However, probing the molecular details of mutation-induced subtle structure dynamics is still challenging.
From tape measures to space lasers: Quantifying biomass of the world's tallest forests
In this era of accelerating climate crisis, accounting for all aspects of Earth's carbon cycle is a crucial task. The magnitude of atmospheric carbon burden means trees and forests are limited but important instruments among a suite of mitigation options.
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much of each element we observe in
Researchers find cryptic genetic element in the human gut that could serve as a sensitive biomarker
A component of the human intestinal flora that has been little studied to date is the focus of a new study from Germany. Plasmids are small extrachromosomal genetic elements that frequently occur in bacterial cells and can influence microbial lifestyles—yet their diversity in
L-cyclodextrins synthesized in the lab for the first time
A team of chemists at Northwestern University has successfully synthesized three L-cyclodextrins in the lab for the first time. In their study, published in the journal Nature Synthesis, the group used a one-pot strategy to achieve the feat.
How do Australia's desert animals avoid inbreeding during dry spells?
Some Australian desert mammals use distinct strategies to promote evolutionary fitness in response to changing environmental conditions over short timescales, according to a new study.
Illuminating the path to hearing recovery: Structural insights into a receptor protein's role in auditory function
Researchers have worked to uncover the mysteries surrounding a specific receptor protein associated with hearing. Professor Yunje Cho's research team from the Department of Life Sciences at Pohang University of Science and Technology (POSTECH, Republic of Korea) has
Twisted pollen tubes induce infertility in plants with multiple sets of chromosomes
Most mammals and humans have a double set of chromosomes—and as a rule, plants do, too: One set comes from the father, the other from the mother. Such organisms are called diploids. However, sometimes the number of chromosome sets doubles from one generation to the next: one
Climate-change-driven cold snaps threaten marine life
Tropical marine species venturing into new areas as the climate changes could fall victim to another effect of the phenomenon—as bursts of cold water from the deep sea suddenly kill them.
First-of-its-kind study shows Florida Wildlife Corridor eases worst impacts of climate change
From rising temperatures and altered precipitation patterns to intense weather events such as hurricanes, Florida is experiencing significant climate-related challenges in tandem with skyrocketing insurance rates. As the state's population continues to surge by 1,000 new
