There's a Moon cube now! At least, it looks that way based on some intriguing photos from the Chinese lunar rover Yutu-2, released by the country's space agency this week. The photos show a distant object that looks like a perfect cube, and China say the rover is headed to check it out. It's worth worth noting a few caveats about the photo, spotted yesterday by space journalist Andrew Jones, who
Florida's very cool and normal governor is proposing a "civilian military force" that would be under his control — rather than the Pentagon's. CNN reports that Florida Governor Ron DeSantis's Florida State Guard would "not encumbered by the federal government." This wasn't just an off-handed suggestion, either. DeSantis said that he's going to ask the state legislature for $3.5 million to equip a
Astronomers from the University of Texas have spotted a gigantic black hole at the heart of our galaxy's many dwarf satellite galaxies — meaning that, in intergalactic terms, it's just a stone's throw away from our own Solar System. The newly discovered black hole, dubbed Leo I, is roughly the same size as the suspected black hole at the center of the Milky Way. It also appears to be a bit of an
A multi-institutional team of astrophysicists headquartered at Boston University, led by BU astrophysicist Merav Opher, has made a breakthrough discovery in our understanding of the cosmic forces that shape the protective bubble surrounding our solar system—a bubble that shelters life on Earth and is known by space researchers as the heliosphere.
To look back in time at the cosmos's infancy and witness the first stars flicker on, you must first grind a mirror as big as a house. Its surface must be so smooth that, if the mirror were the scale of a continent, it would feature no hill or valley greater than ankle height. Only a mirror so huge and smooth can collect and focus the faint light coming from the farthest galaxies in the sky — ligh
Light is an electromagnetic wave: It consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of oscillations per second, measured in Hertz (Hz). Our eyes can detect frequencies between 400 and 750 trillion Hz (or terahertz, THz), which define the visible spectrum. Light sensors in cell phone cameras ca

Knowing a baby's whole genetic code would help detect a range of health problems, but would not replace need for some existing tests Scientists raise concerns over UK baby genome sequencing plan What is the current newborn screening? All babies in the UK are offered the "heel prick" or blood spot test at around five days old to screen for nine serious health conditions, including cystic fibrosis,
Once, while on a trip to Maui, Haruki Murakami caught a glimpse of a garment that fascinated him—a simple yellow T-shirt that read TONY TAKITANI in blue letters. "What kind of person could Tony Takitani be?" the novelist wondered. So he bought the shirt (which cost just $1), wrote a short story inspired by the name, and eventually met the real-life Mr. Takitani (a political candidate turned lawye
Biomedical Engineering Professor Corey Neu and Ph. D. student Benjamin Seelbinder of the University of Colorado at Boulder wanted to answer two fundamental questions. How do cells adapt to their environment and how does a mechanical environment influence a cell?
A team of researchers at RWTH Aachen University and the University of Jyväskylä has developed a system based on machine learning and computationally derived descriptors that can be used to find special kinds of catalysts. In their paper published in the journal Science, the group describes using machine learning algorithms to find patterns in known types of ligands and applying the results to find
Anne S. Meyer, an associate professor of biology at the University of Rochester, and her collaborators at Delft University of Technology in the Netherlands recently developed a 3D printing technique to engineer and study biofilms—three-dimensional communities of microorganisms, such as bacteria, that adhere to surfaces. The research provides important information for creating synthetic materials a
An organism's genome could be compared to a complex system of instructions that allows it not only to develop, but also to carry out all the activities essential to its survival. To do this, this genome needs to be expressed correctly, i.e. these instructions need to be "read" properly, and the information it contains must not be altered or degraded over time.
People in the UK of Bangladeshi or Pakistani heritage are more likely to live in households that include schoolchildren and people aged 70 or older – a factor that may explain why people from these backgrounds were more likely to die from covid-19 during the country's second wave
Environmental scientist Marc-Antoine Longpré with City University of New York is suggesting in a Perspective piece published in the journal Science that lessons can be learned from the unexpected eruption of Cumbre Vieja last fall. In his paper, he notes that the timing, explosive power and effusiveness of the blast caught most vulcanologists off guard.
Researchers have identified 187 individual North Atlantic right whales—about 40 percent of the catalogued population—in Canada's Gulf of St. Lawrence during the summer. They used photographs of North Atlantic right whales collected during surveys conducted between 2015 and 2019. Many of the right whales remain in the area through the summer and autumn, feeding and socializing primarily in southern

This week she talks with three artists and one writer, who all work on titles for DC Comics, about their collaboration on the page and their friendship off of it. They discuss how working in comics can be iso
Researchers report that an abbreviated, seven-item scale can help determine with high validity a person's level of wisdom, a potentially modifiable personality trait that has been shown to have a strong association to well-being.
Suburbia is neither glamorous nor picturesque. But this is precisely what makes it rich terrain for my books It's early December and in my corner of southeast London the Christmas illuminations are going up. Garden gnomes may have fallen out of fashion, but their seasonal equivalent, inflatable Santas, are very much in evidence. There are some pockets of tasteful conformity, where entire streets o
A global study into causes of stroke has found that one in 11 survivors experienced a period of anger or upset in the one hour leading up to it. One in 20 patients had engaged in heavy physical exertion. The suspected triggers have been identified as part of the global INTERSTROKE study, which analyzed 13,462 cases of acute stroke, involving patients with a range of ethnic backgrounds in 32 countr
For most everyone, 2021 has been a long and lonely year. Pop stars, it seems, are no exception. Although music about heartbreak has been around for as long as there's been music, this past year's charts have looked particularly lovelorn. Pop music has been a months-long opera of celebrity splits. We went from Olivia Rodrigo's world-conquering "Drivers License" in January to Adele's new album, 30
How can we understand the activity of wild bats? Mostly soundless, flying in the dark, bats feed at night and evade our senses. Now, an international research team has developed a new non-invasive method 'bat point counts' by combining modern sensing technologies — thermal, ultrasonic and near-infrared — to detect, identify and count all bats flying around in a certain range.
People choose whether to seek or avoid information about their health, finances and personal traits based on how they think it will make them feel, how useful it is, and if it relates to things they think about often, finds a new study.
In a recent review article published online in National Science Review, Prof. Shenjian Chen (Nanjing University) and Prof. Stephen Olsen (University of Chinese Academy of Sciences) review the major progress of the BESIII experiment in searching for new physics in Charm physics energy region, and prospect the potential of new physics search in the future.
Advancing our understanding of the human brain will require new insights into how neural circuitry works in mammals, including laboratory mice. These investigations require monitoring brain activity with a microscope that provides resolution high enough to see individual neurons and their neighbors.
In "Feeling & Knowing: Making Minds Conscious," neuroscientist Antonio Damasio explores the mystery of consciousness and its connection to feeling. For Damasio, consciousness is inextricably linked to feelings and sensations in our bodies that we then, crucially, relate back to our sense of personhood.
An international team of scientists, in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate together with other institutions from Spain, Italy, Germany, Belgium, UK, and Mexico, has been able to measure the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is th
As robotic devices such as artificial prosthetics and human-computer interfaces are increasingly integrated into society, researchers have been looking more deeply into the sensitivity of the devices that serve the same function as hands. Human fingertips are remarkably sensitive. They can communicate details of an object as small as 40μm (about half the width of a human hair), discern subtle diff
Researchers found that probiotics significantly improve the symptoms of pregnancy-related nausea, vomiting and constipation. Nausea and vomiting affect about 85% of pregnancies and can significantly impact quality of life, particularly during early pregnancy.
An author with ties to researchers believed to have published hundreds of problematic papers has earned his ninth retraction, this time for forged authorship.

Tropical forests are disappearing at an alarming rate through deforestation, but they also have the potential to regrow naturally on abandoned lands. This has been shown by an international study led by scientists from Wageningen University. How a forest recovers, depends on the amount of rainfall, the age of the forest, and the functional characteristics of the tree species.
Having an elevated resting heart rate in old age may be an independent risk factor of dementia, according to a new study. Since resting heart rate is easy to measure and can be lowered through exercise or medical treatment, the researchers believe that it may help to identify people with higher dementia risk for early intervention.
Unusual ways of investment, such as collecting toys, can generate high returns. For example, secondary market prices of retired LEGO sets grow by 11% annually, which is faster than gold, stocks, and bonds, HSE University economists say. Their paper was published in the Research in International Business and Finance journal.
By performing a series of real and 'fake' flybys, ESA's Mars Express has revealed how Mars' largest moon, Phobos, interacts with the solar wind of charged particles thrown out by the Sun—and spotted an elusive process that has only been seen at Phobos once before.
A rare total solar eclipse in Antarctica this weekend (Saturday 4 December) is giving researchers a unique opportunity to learn more about how solar eclipses affect space weather. The next total eclipse in Antarctica will not be until 2039.
Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common: more than about a quarter of all main-sequence stars have debris disks and, since these disks can be hard to detect, it is likely that the fraction is even higher. Current instruments are only able to detect debris disks in systems th
Researchers from The University of New Mexico and California Polytechnic University find increased employment, especially in manufacturing, following the opening of legal recreational cannabis dispensaries. They found no evidence of declines in worker productivity, suggesting that any negative effects from cannabis legalization are outweighed by the job growth these new markets create.
In their recent publication, "Why is Denali (6,190 m) so big? Caught inside the tectonic wake of a migrating restraining bend," Jeff A. Benowitz and a research team from the University of Massachusetts Amherst, Virginia Tech, and the South Dakota School of Mines and Technology in the U.S., documented the evolution of the Mount McKinley bend of the Denali Fault.
As our solar system formed 4.6 billion years ago, small grains of dust and ice swirled around, left over from the formation of the Sun. Through time, they collided and stuck to each other. As they grew in size, gravity helped them clump together. One such rock grew into the Earth on which we live.
Scientists have measured the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution.
A 35-year-old man only has a 1.5 percent chance of dying in the next ten years . But the same man at 75 has a 45 percent chance of dying before he reaches 85. Clearly, aging is bad for our health. On the bright side, we have made unprecedented progress in understanding the fundamental mechanisms that control aging and late-life disease. A few tightly linked biological processes, sometimes called

Business leaders and management experts often encourage people to speak up in the workplace. Suggesting a creative idea or a more efficient way to work can help companies overcome challenges and meet goals. But new research shows another, more subtle and often overlooked form of speaking up has a big effect on the way work gets done and how teams come together.
Our understanding of how microscopic structure and changes in the shape of food affect food texture remains underdeveloped, so researchers from Denmark and Germany conducted a series of experiments relating food microstructure and rheology to texture. They used coherent anti-Stokes Raman scattering microscopy to relate the molecular makeup of the fat in foods with the rheological and mechanical pr
Researchers have developed an approach to print skin equivalents, which may play a future role in facilitating the healing of chronic wounds. They used suspended layer additive manufacturing, creating a gel-like material to support the skin equivalent that can then support a second phase of gel injection. During printing, the skin layers are deposited within the support gel. After printing, the te
The brain is indeed a target for treating ALS (amyotrophic lateral sclerosis), scientists have discovered. This flips a long-standing belief the disease starts in the spinal motor neurons and any therapy would need to target the spine as the key focus. The new study shows the brain degenerates early in ALS, sends warning signals and shows defects very early in the disease. Degeneration of brain mo
Scientists have collaborated to build a structurally-motivated deep learning method built from recent advances in neural language modeling. The team's deep-learning model, called D-SCRIPT, was able to predict protein-protein interactions (PPIs) from primary amino acid sequences.
Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers have found that the process of packaging neurotransmitters may be responsible for this energy drain.

A new analysis of a skeleton found in a tomb in China has uncovered the mystery of 1,300-year-old murder—and cleared the victim's name. The mystery began in 2002 when construction crews in the Ningxia region of China discovered an ancient tomb. Several years later, archaeologists discovered a male skeleton in a large shaft leading down into the tomb. "…this was definitely a homicide case." The sh
It wasn't that long ago that the very thought of wearing a computer on your face sounded like a futuristic, sci-fi fantasy, right up there with flying cars. But while flying cars are still beyond the grasp of most mortals for now , so-called smart glasses are already here. Smart glasses are essentially wearable computer glasses that function in a myriad of ways, depending on the type and purpose.
As the world's temperatures rise, tidewater glaciers are receding and melting, releasing air trapped in the ice. Scientists can listen to the release of the air and potentially use the sounds to help them gauge the impact of climate change on the ice floes.

"Often, when we get outside of our cultural bubble, we realize we've been sociali
Invasive ant species can be found in almost every ecosystem on earth, but the impact these invaders may have on plant health has only recently been investigated by scientists. A new study published in Journal of Ecology is the first of its kind to find that invasive ants can disrupt plants' growth and photosynthesis by nesting at their roots—potentially threatening plants in tropical and subtropic
Researchers have been able to document and visualize hearing loss-associated genes in the human inner ear, in a unique collaboration study between otosurgeons and geneticists. The findings illustrate that discrete subcellular structures in the human organ of hearing, the cochlea, are involved in the variation of risk of age-related hearing loss in the population.
Researchers have found that blocking the action of a protein called interleukin 6 (IL-6), part of the immune system, could resolve the delirium that often accompanies urinary tract infection (UTI) in elderly patients. Their study could pave the way for clinical trials of IL-6 inhibitors as a treatment for UTI-associated delirium in humans.
A new study uses novel single-cell profiling techniques to reveal how plants add new cell layers that help them resist climate stressors like drought or flooding. The research focuses on corn — a critically important crop around the world — in an effort to create a cell-by-cell map of the plant's root system, which mediates drought stress and absorbs nutrients and fertilizer from the soil.
Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications of embryonic stem cell-based models of early mammalian embryogenesis on the function of this structure.
Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive.

How can we understand the activity of wild bats? Mostly soundless, flying in the dark, bats feed at night and evade our senses. Many bats can use echolocation to hunt and can avoid the traditional nets used to capture them; those that do not "echolocate" cannot be detected by ultrasound bat detectors. Now, an international research team led by the University of Göttingen has developed a new method

His warnings have gone largely unheeded, while wild pigs continue rapidly expanding across Western Canada, with no nationally co-ordinated science-based containment strategy in place and limited provincial resources available. For Brook, it's a recipe for disaster.
In nature, the roots of healthy plants are colonized by complex microbial communities of bacteria and filamentous eukaryotes (i.e., fungi and oomycetes, Fig. 1), the composition of which profoundly influences plant health. Maintaining a microbial equilibrium in their roots is very important for plants to remain healthy, however, the means by which this is achieved by plants is still largely unknow
Physicists said they have finally experimentally documented quantum spin liquids, a long sought-after exotic state of matter. The work marks a big step toward being able to produce this elusive state on demand and to gain a novel understanding of its mysterious nature.
Researchers have used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the polycrystalline material SrTiO3.

With nanotechnology we can understand, mimic, and modulate our immune system. For her Ph.D. research, Annelies Wauters studied how tiny nanocarriers can be used to control the immune system, and target and activate immune cells to fight cancer cells. Wauters defends her thesis on December 3rd.
The first large scale characterisation of methane emissions in Irish beef cattle conclusively shows that some beef cattle can produce up to 30% less methane emissions, on average, for the same level of productivity.
In Japan, all residents are responsible for sorting their trash into several waste streams. They are required to label clear garbage bags with their name and address, so the contents can be easily identified. If anything is sorted incorrectly, they will have their bag returned and be told to sort their trash correctly. This strict system has resulted in about 99 percent of Japan's municipal waste
Surveys of the montane forests of Kon Plong, in Vietnam's central highlands, conducted by Fauna & Flora International (FFI) and our local partner GreenViet, have revealed a rich reservoir of wildlife. This is the first time that these forests have been systematically and intensively surveyed and, in total, the researchers documented nearly 1,000 species of vertebrate and plant.
Engineers only get one shot at making a spacecraft work as intended—or at least they only get one shot in space. In the preparation leading up to that final, climactic moment, there are typically thousands of hours of tests run on numerous systems and subsystems. If all goes well, it bodes well for the mission's overall success, but if problems arise, it's much easier to address them on the ground
From power plants to coffee cups or your childhood home, everything that makes up the economy has a life expectancy. Much of what we make and consume lasts just weeks, months or years. However, lots of infrastructure instead lasts lifetimes, binding future generations into pathways chosen long before them.

Tänk dig att du behöver ett mångsidigt och lättkontrollerat system för att utforska material ända n
Each year 6-7 billion male chicks are culled, because only females are needed for egg laying. Many other animals are also culled because one sex is desired either for food production or research. There are many research questions that are sex specific, and therefore large numbers of a single sex of a specific strain of mice may be required. Culling is a crude way to achieve these ends, and raises
Researchers at the University of Michigan and Seoul National University of Science and Technology have devised a new method for manufacturing devices that require precisely sized and positioned micro- and nanoscale particles. The technique is suitable for a wide array of assembly of micro- and nanoscale objects, and useful for electronic devices, and biological applications.
The cost of sequencing has gone down tremendously. But still it is not used in daily practice. One of the reasons for this is that the processing of the raw data into useful insights takes a long time (several days for whole genome sequencing) and requires a lot of expensive resources (such as servers that need to be rented in a data center).
