The method cracks a complex equation that can enable improved control of the random and fast-moving moving electrons in the fuel for fusion energy.
Genetic assessment of captive gibbons to identify their species and subspecies is an important step before any conservation actions. A group of wildlife researchers recently discovered a previously unknown population of white-handed gibbons (subspecies lar) from Peninsular Malaysia.
In recent years 3D printing, also known as additive manufacturing, has established itself as a promising new manufacturing process for a wide variety of components. Dr. Dmitry Momotenko, a chemist at the University of Oldenburg, has now succeeded in fabricating ultrasmall metal objects using a new 3D printing technique. In a paper published together with a team of researchers from ETH Zurich (Swit
For decades, historians have debated whether an infamously violent Viking torture ritual ever really happened, or if it was a misunderstood or embellished story passed down through poetry over the centuries.
For many people around the world, the very first moments of the new year will be filled with the sounds and colorful light shows of fireworks. From loud bangs to long whistles, bright reds to pale blues, there are thousands of variations of fireworks and an entire branch of chemistry that explores these fun explosions.
An asteroid impact can be enough to ruin anyone's day, but several small factors can make the difference between an out-of-this-world story and total annihilation. In AIP Advances, a researcher from the National Institute of Natural Hazards in China developed a computer simulation of asteroid collisions to better understand these factors.

They are ideal for health care within clinical settings, drug discovery, food safety and quality control, and environmental monitoring.
All of us can probably remember a time when we felt lonely. In the UK, around 45% of people report experiencing loneliness—with 5% of people experiencing severe loneliness. With reports that loneliness has been on the rise since the start of the COVID-19 pandemic, there are concerns that it could reach epidemic proportions by 2030, unless action is taken.
Birds of a feather flock together. The popular saying applies to politics and to the computational analysis of complex networks in research on corruption, judging from a study by scientists at the University of São Paulo in Brazil.
The original iPS cells were reprogrammed by transducing four genes: OCT3/4, SOX2, KLF4, and c-MYC. Later experiments would show that c-MYC can be replaced with MYCL. Both are MYC proteins and thus oncogenes, but animal experiments have demonstrated that iPS cells reprogrammed using MYCL are less likely to cause tumors than iPS cells reprogrammed with c-MYC. Furthermore, MYCL enhances the reprogram
When cell phones, electric vehicle chargers, or other electronic devices get too hot, performance degrades, and eventually overheating can cause them to shut down or fail. In order to prevent that from happening researchers are working to solve the problem of dissipating heat produced during performance. Heat that is generated in the device during operation has to flow out, ideally with little hin
Genes lacking a particular structure known as CpG islands tend to go haywire in older cells, a study finds, potentially contributing to key facets of aging. But it's not yet clear if the relationship is causal.
Just like humans, New Caledonian crows are particularly careful when handling their most valuable tools, according to a new study by researchers from the University of St Andrews and the Max Planck Institute of Animal Behavior in Konstanz, Germany. The research reveals that crows are more likely to store relatively complex and efficient foraging tools for future use than more basic tools.
The interaction of fungi and bacteria in the transport of viruses in the soil ecosystem has been examined by a UFZ research team in a study recently published in The ISME Journal. The scientists showed a novel mechanism of viral transport by bacterial shuttles traveling along fungal hyphae. Bacteria thereby benefit from taking along viruses on the conquest of new habitats.
The protein tBID can trigger programmed cell death (apoptosis) by inducing damage in the energy suppliers of the cells, the mitochondria. Apoptosis is essential for maintaining tissue balance. In addition, apoptosis plays a critical role as a defense mechanism and in the elimination of damaged or redundant cells in our bodies. Impaired apoptosis has been linked to many human diseases, from cancer
Plant flavonoid accumulation is promoted by various environmental factors, including excess light, UV radiation, drought, and low temperatures. Increased flavonoid content helps plants to maintain normal growth and development by eliminating excess reactive oxygen species (ROS) produced under adverse conditions. Intriguingly, high temperature, a common environmental stress, induces ROS production

"Do you want a boy or a girl?" can be an awkward question. But in certain circles, it's a question that's asked every day. Take agriculture. In a perfect world, most cows would only birth females. Chicks would grow up to be all hens. "Sexing" a farm animal when they're at a young age wouldn't be a thing—especially when it means male animals, without the ability to produce milk or eggs, are often

By taking a closer look at lizards, researchers found the first animal example of apparent changes in tooth type in specific regions of the jaw. The results are relevant to multiple research areas all the way from palaeontology to regenerative medicine.
Family relationships are on many people's minds during the holiday season as sounds and images of happy family celebrations dominate the media. Anyone whose experiences don't live up to the holiday hype may find this difficult or disappointing, but those feelings may be felt even more acutely among those involved in family rifts.
Right now, Christmas nativity scenes across the world feature three kings—also known as the "wise men" or Magi—bringing gifts of gold, frankincense and myrrh to the newborn baby Jesus in Bethlehem. In the Bible, Matthew's gospel tells us that the wise men "saw the child with his mother Mary, and they bowed down and worshiped him. Then they opened their treasures and presented him with gifts of gol
Earthquakes cannot be forecast like weather, but fault line characteristics, such as structural maturity, can give hints about how a future earthquake may act. Structural maturity is related to the age of the fault, but especially important is its "experience," how much a fault has developed and changed over time and activity.
Due to their unique characteristics, gallium-based liquid metal (LM) nanoparticles have been applied in various research fields. LM nanoparticle surface-modification design is essential for enhancing the original LM properties and physicochemical multifunctionalization.
Every winter when Lake Suwa in Japan freezes, locals believe that the Shinto male god Takeminakata crosses the frozen lake with his dragon to visit the female god Yasakatome. He leaves only his footsteps on the ice in the form of a sinusoidal ice ridge called the omiwatari.

Recently, an email asked about CO 2 and the absorption of infrared (IR) radiation (specifically mentioning
Solar energy is probably the best candidate in my opinion to power the world in the future but I think the solar panels won't be placed on earth at all. They will be placed on satellites in space orbiting the sun. Hundreds of thousands of them if not millions. We will gather the materials to build those satellites from mars, the moon, asteroids and other celestial bodies including earth of course
A sizable minority of people over 50 are feeling lots of stress, including about their risk of getting COVID-19, a recent poll shows. While most people polled are finding joy and staying resilient amid the pandemic, women and those in their 50s and early 60s are more likely to report feeling a lot of stress. Those stress levels were highest—and joy levels lowest—among people who say their overall

A recent study in Science Advances shows that extreme weather conditions affect species-rich forests less than forests with fewer species. In addition, species-rich forests also produce more wood—largely due to the diversity of functional characteristics among species.
Living organisms, viruses, and technological devices, have water layers between their cells or parts and can die or stop working when dehydrated. But why water and not any other fluid? What makes water unique under such conditions when it is in these tiny structures?
According to mothers' experiences, the daily life during the coronavirus pandemic and lockdown in the spring of 2020 blurred the boundaries between work and family responsibilities and roles. In families where the division of childcare responsibilities was unequal before the pandemic and where only the mother switched to working from home, mothers were especially likely to feel that they shouldere
As people across the Midwestern U.S. take stock of the devastation from a Dec. 10 trail of tornados that blew across the region, data and images from NASA Earth-observing satellites aid first responders and recovery agencies in assessing the damage and help researchers understand the nature of these unusually powerful storms.
In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth—a sudden flare of light caused by the titanic explosion accompanying the death of a massive star. While most astronomical discoveries ar
The National Science Foundation (NSF) and the board of the Atacama Large Millimeter/submillimeter Array (ALMA) have approved a multi-million dollar upgrade project for the Observatory's 1.3mm (Band 6) receivers through the North American ALMA Development Program. The receivers—originally built, and to be upgraded, by the Central Development Laboratory (CDL) at the National Radio Astronomy Observat
Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes happening in the rock over time—a complex picture that can be difficult to capture.
Thermoplastic elastomers (TPEs—sometimes called thermoplastic rubbers) are a chemically-bonded combination of multiple polymers ("copolymer")—typically a plastic and a rubber—that have both thermoplastic and elastomeric properties. The thermoplastic property is useful in injection molding, while the elastomeric property gives the object the ability to stretch and return to nearly its original shap
Scientists at the National Renewable Energy Laboratory (NREL) have experimentally synthesized a nitride perovskite that previously only existed in theory and measured its properties in collaboration with researchers at the Colorado School of Mines.
Researchers recently made a major discovery — 14 new species of shrews, which is the largest number of new mammals described in a scientific paper since 1931. After a decade-long journey taking inventory of Indonesian shrews living on the island of Sulawesi, a group of scientists has identified 14 new endemic species.
A research team has developed a new artificial photosynthesis device with remarkable stability and longevity as it converts sunlight and carbon dioxide into two promising sources of renewable fuels — ethylene and hydrogen.

Researchers found a way help to defend against hypoglycemia by boosting hormonal defense systems. The team believes they have identified a promising target in the brain could be useful for future drug development to create an anti-hypoglycemia drug.
Superconducting materials show zero electrical resistance at low temperatures, which allows them to conduct 'supercurrents' without dissipation. Recently, a group of scientists developed an inexpensive, scalable way to produce high-temperature superconductors using 'grain boundary engineering' techniques. The new method could help develop stronger, inexpensive, and high operating temperature super
Several tree-ring studies have been carried out in the Hengduan Mountain (HM) region. However, long-term growth trends and physiological responses of high-elevation forests to atmospheric carbon dioxide (CO2) rise and climate change in the HM region is still not clear.
Agriculture in Northeast China, where most of the country's fertile black soil is located, has been recognized as crucial for Chinese food security. However, the soil is in a critical condition due to years of intensive production and overuse of fertilizer.
Returning the biomass from logging to the soil and planting legume cover crops enable rapid restoration of the main soil functions, just 18 months after clear-cutting of an aging rubber plantation. A team of scientists has demonstrated this in two sites in Côte d'Ivoire since 2017. While pressure on land and the fight against deforestation mean producers are obliged to continuously replant on the
The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They identified striking differences in the development of teeth. The teeth of the mutant lizard exhibited a large size and an unusual attachment type in specific locations along the jaw.
When stacking two layers of van der Waals (vdW) materials, a moiré pattern is produced by the modulation of the long wavelength periodic potential. The moiré pattern is a promising means in engineering both the atomic geometry and electronic structure. A variety of emergent phenomena have been discovered in twisted vdW bilayers of graphene or semiconducting transition-metal dichalcogenide (2H-TMD)
Hydroxyl groups are among the major active surface sites over metal oxides. However, their spectroscopic characterizations have been challenging due to limited resolutions, especially on hydroxyl-rich surfaces where strong hydroxyl networks are present.
Researchers from China, the U.K., Netherlands, and Australia have revealed orbital-scale Asian monsoon variability and dynamics under conditions of high atmospheric CO2 concentrations and a warm climate during the late Oligocene.
(Photo: Boeing) The word "metaverse" has been uttered more times in the last few months than any of us would have expected, but Facebook — sorry, Meta is a powerful force on the internet. If Mark Zuckerberg wants the metaverse, Facebook is probably going to make it happen in some capacity, and Boeing wants in. The troubled aerospace firm hopes to improve its design process by doing it in the meta
Far, far away from the presumably toasty place you're reading this, on the Walgreen Coast of Antarctica, there's a massive chunk of ice known as the Thwaites Glacier. It's the widest glacier in the world, and scientists are worried that a large volume of its ice could end up in the oceans very soon. This has earned Thwaites a nickname: Doomsday Glacier. Researchers from the American Geophysical U
To the left and right, the landscape drifts idly by, the track in front of you. Suddenly, a fire. The tension builds. The ride reaches its highest point. Only one thing lies ahead: the abyss. Plummeting down into the depths of the earth. These are scenes of a rollercoaster ride as experienced by participants in a recent study. However, not in real life, but virtually, with the help of virtual real

Do election campaigns shape public policy as they are supposed to in a democracy? Do the laws passed during a mandate really address the issues debated during elections? For countries with political systems as varied as Germany, Denmark, France and Italy, political scientists Isabelle Guinaudeau (CNRS) and Emiliano Grossman (Sciences Po)1 answer in the affirmative. To reach this conclusion, they u
High-resolution spectroscopic observations of a stellar flare on a small, cool star indicate the possibility of coronal rain, a phenomenon that has been observed on our sun but not yet confirmed on a star of this size. This faint star, known as vB 10, which is about a tenth the size of the sun and produces less than 1% of the sun's energy, was studied using the Penn State Habitable-zone Planet Fin
The villainous boss memes, workday gripes, and big corporation throwdowns shoot fast and furious on the Reddit forum r/antiwork, which has become a viral post Howitzer. In one recent post, a Calm app tweet poses this well-meaning question: "What could your employer do to better support your mental health?" The Redditor slyly responded with "Double my salary." Another Redditor lamented being told t

Spanish company Nueva Pescanova is close to opening a commercial octopus farm in the Canary Islands. The purpose of this farm is to raise octopuses (and yes, that is an acceptable plural) for food, sparking another round in the debate over the ethics of raising animals for food. This also comes on the heels of the UK adding the octopus to the list of "sentient" animals , garnering for them certai
Speciallæge Marianne Rosendal, der er forperson for Dansk Selskab for Funktionelle Lidelser (DASEFU), mener ikke, at de nye guidelines fra NICE vedrørende behandling af personer med ME er helt inden for skiven. Hun er heller ikke enig i ME-foreningens kritik af den nuværende måde at behandle patienter med ME i Danmark.
Like many cities across the world, Glasgow—host to the UN climate conference COP26—has a target to achieve net zero greenhouse gas emissions by 2030. This is a massive undertaking for any city. It means emissions from homes, businesses, waste and transport have to be reduced or offset as much possible.
Sign up for Caleb's newsletter here. If I were Dr. Seuss, I would simply begin: "What does it mean / When I look at the screen / at a show or a meme / and I say 'I feel seen'?" I know what it means when someone says they feel heard—they feel like someone has really listened to them, as if their words have been paid attention to. I know what it means when someone says they feel touched—they feel l
This year, we have taken on two massive existential threats: the ongoing coronavirus pandemic and the climate emergency. Though we are a long way off solving these crises, there are reasons for rational optimism in 2022
