A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD).
James Carville is furious. “It’s the LAW!!! If you do not enforce it, Dems will look as weak as people think they are,” he texted me earlier this week. “I would ask if we could use DC jail for Bannon.” What has Carville itching to put former President Donald Trump’s ex-adviser behind bars? Defiance. The special congressional committee charged with investigating the January 6 insurrection gave for
Doctors from the U.K. report an intriguing case in which an octogenarian woman who smokes a pack of cigarettes per week refused treatment for her lung cancer — but the tumor shrankanyway. Now, the trio of doctors suspects that the woman’s daily self-administration of CBD oil may be the reason for her recovery, according to a paper they published in the journal BMJ Case Reports on Thursday.

Analysis: as Covid cases reach 40,000 a day, scientists think normalisation is partly to blame for the lack of public reaction Coronavirus – latest updates See all our coronavirus coverage It is one of the conundrums of the current phase of the Covid pandemic: the UK has among the highest number of infections across the world and a death toll that continues to steadily climb, yet the national moo
I first noticed that something weird was happening this past spring. In April, the number of workers who quit their job in a single month broke an all-time U.S. record. Economists called it the “Great Resignation.” But America’s quittin’ spirit was just getting started. In July, even more people left their job. In August, quitters set yet another record. That Great Resignation? It just keeps gett
Deep Breath Thanks to some biological tinkering, a team of scientists found a way to keep tadpoles alive, even after taking away their ability to breathe. The Ludwig Maximilians University researchers injected photosynthetic algae into the tadpoles, creating a symbiotic relationship between amphibian and microbe that keeps the amphibians alive without any environmental oxygen, The Scientist repor
Never Gonna In April, an enterprising 14-year-old high school student and white hat hacker caused all displays in every school making up the Township High School District 214, the second-largest high school district in Illinois, to play the music video to Rick Astley’s 1980s hit “Never Gonna Give You Up.” In other words, the student literally rickrolled their entire school district — and in perfe
Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use
A team of researchers with members affiliated with a large number of institutions across Japan has found that the Gulf stream and Kuroshio are synchronized on a decadal time scale.

The Roman Empire was ruled by 175 men, from Augustus (63 BCE-19 CE) to Constantine XI (1405-53), including the Eastern or Byzantine Empire after the split in 395 CE, but excluding those who did not rule in their own right because they were minors during regencies or co-emperors.
Plants are under attack by a variety of insect species. They have defense mechanisms to deal with this, including chemicals or sturdier leaves. But it's now been found that when wild black mustard plants defend themselves against an initial enemy, they already anticipate the need to later fend off other, different enemies. In fact, they even prepare for the most likely sequence of attackers. This
Four weeks on a diet of highly processed food led to a strong inflammatory response in the brains of aging rats that was accompanied by behavioral signs of memory loss, a new study has found. Researchers also found that supplementing the processed diet with the omega-3 fatty acid DHA prevented memory problems and reduced the inflammatory effects almost entirely in older rats.
Archaeologists find remains of fugitive during first dig at site near Pompeii in almost three decades The partially mutilated remains of a man buried by the AD79 eruption of Mount Vesuvius at Herculaneum, the ancient Roman town close to Pompeii, have been discovered in what Italy’s culture minister described as a “sensational” find. Archaeologists said the man, believed to have been aged between

The last 20 months turned every dog into an amateur epidemiologist and statistician. Meanwhile, a group of bona fide epidemiologists and statisticians came to believe that pandemic problems might be more effectively solved by adopting the mindset of an engineer: that is, focusing on pragmatic problem-solving with an iterative, adaptive strategy to make things work. In a recent essay, “ Accounting

NASA’s Lucy spacecraft, named for an early human ancestor whose skeleton provided insights into our species’ muddled origins, has begun the first leg of its 12-year journey. Lifting off from Cape Canaveral early Saturday morning on an Atlas V rocket, Lucy is headed to study asteroids in an area around Jupiter that’s been relatively unchanged since the Big Bang. It will venture farther from the su
Researchers found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional.
In the early solar system, a 'protoplanetary disk' of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new study suggests that a mysterious gap existed within this disk around 4.567 billion years ago, and likely shaped the composition of the solar system's infant planets.
Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival.

Dysregulation of these processes, due to environmental or genetic causes, can lead to a variety of pathological conditions ranging from obesity to anorexia. Melanocortins and endogenous cannabinoids (eCBs) have been implicated in…
Chronic stress could induce severe cognitive impairments. Despite extensive investigations in mammalian models, the underlying mechanisms remain obscure. Here, we show that chronic stress could induce dramatic learning and memory deficits in Drosophila melanogaster. The chronic stress–induced learning deficit (CSLD) is long lasting and associated with other depression-like behaviors. We…
Magnetic nanoparticles are robust contrast agents for MRI and often produce particularly strong signal changes per particle. Leveraging these effects to probe cellular- and molecular-level phenomena in tissue can, however, be hindered by the large sizes of typical nanoparticle contrast agents. To address this limitation, we introduce single-nanometer iron oxide…
Type II NADH dehydrogenases (NDH2) are monotopic enzymes present in the external or internal face of the mitochondrial inner membrane that contribute to NADH/NAD+ balance by conveying electrons from NADH to ubiquinone without coupled proton translocation. Herein, we characterize the product of a gene present in all species of the…
Information about features in the visual world is parsed by circuits in the retina and is then transmitted to the brain by distinct subtypes of retinal ganglion cells (RGCs). Axons from RGC subtypes are stratified in retinorecipient brain nuclei, such as the superior colliculus (SC), to provide a segregated relay…
In nature, microorganisms could sense the intensity of the incident visible light and exhibit bidirectional (positive or negative) phototaxis. However, it is still challenging to achieve the similar biomimetic phototaxis for the artificial micro/nanomotor (MNM) counterparts with the size from a few nanometers to a few micrometers. In this work,…
Hybridization is among the evolutionary mechanisms most frequently hypothesized to drive the success of invasive species, in part because hybrids are common in invasive populations. One explanation for this pattern is that biological invasions coincide with a change in selection pressures that limit hybridization in the native range. To investigate…
In vivid detail, Bak-Coleman et al. (1) describe explosively multiplicative global pathologies of scale posing existential risk to humanity. They argue that the study of collective behavior in the age of digital social media must rise to a “crisis discipline” dedicated to averting global ruin through the adaptive manipulation of…
The term “de-etiolation” refers to the light-dependent differentiation of etioplasts to chloroplasts in angiosperms. The underlying process involves reorganization of prolamellar bodies (PLBs) and prothylakoids into thylakoids, with concurrent changes in protein, lipid, and pigment composition, which together lead to the assembly of active photosynthetic complexes. Despite the highly conserved…
The low-complexity (LC) domain of the fused in sarcoma (FUS) RNA binding protein self-associates in a manner causing phase separation from an aqueous environment. Incubation of the FUS LC domain under physiologically normal conditions of salt and pH leads to rapid formation of liquid-like droplets that mature into a gel-like…
In our PNAS article “Stewardship of global collective behavior” (1), we describe the breakneck pace of recent innovations in information technology.

Last Hurrah Nuking an incoming asteroid as a last-ditch effort to save the planet has long captivated the imaginations of real-life experts and filmmakers alike. But many astronomers have maintained that it would never work, saying we should come up with other ideas instead. But new research may show that those naysayers are wrong, Gizmodo reports , because computer simulations indicate that a la
The criminal justice system has changed dramatically in the past half century and with these changes has come a greater potential for adolescents to encounter police. A new study examined how adolescents' experiences with police—either directly or vicariously (e.g., via witnessing an encounter)—affected their future orientation during the transition to adulthood. The study concluded that adolescen
A new study explored how prosecutors think about race in criminal justice, providing ideas of how to break the color-blind approach to prosecution that can entrench racial disparities. The study found that prosecutors broadly argue that race should not be considered when processing cases.
Humanity has existed for 300,000 years, give or take a millennium. That might sound like a long time when the average human lives at most a few decades, but it’s really just a cosmic blink of the eye. Even if Homo sapiens exceeds all expectations and survives both political strife and climate change, the sun will eventually turn Earth into a cinder. However, a new discovery from the W. M. Keck Ob

A team of fusion researchers at the Department of Energy's Oak Ridge National Laboratory used datasets from measurements on the Joint European Torus, or JET, tokamak to model an improved method for quantifying the amount of plasma-radiated power during a disruption of normal operations.
Impurities in the plasmas in fusion tokamaks can reduce performance. These impurities are created by interactions between the hot plasma and the metal tokamak walls. These walls are often armored with tungsten. This material resists heat, but degrades over time, releasing impurities into the plasma. Simulations predict how these impurities behave, but they are difficult to measure directly because

I landet, hvor janteloven er opfundet, er vi ikke vant til at løbe rundt og slå os på brystet i begejstring over os selv og vores landsmænd. Men det må være på sin plads at fremhæve, når nogen gør det rigtig, rigtig godt.
Near menopause, the menstrual cycle length often changes, becoming longer. The timing of that change could provide clues to a person’s risk of heart disease, researchers say. A new study, published in the journal Menopause , characterizes cycle-length changes over the menopause transition and found that women whose cycle increased in length two years before their final menstrual period had better
In May 2020, a hole a little smaller than the state of Rhode Island opened up for two weeks in the Last Ice Area, a million-square-kilometer patch of sea ice north of Greenland and Ellesmere Island that's expected to be the last refuge of ice in a rapidly warming Arctic. The polynya is the first one that has been identified in this part of the Last Ice Area.
Researchers have developed a simple spatial light modulator made from gold electrodes covered by a thin film of electro-optical material that changes its optical properties in response to electric signals.
Researchers have discovered how neurons in a small area of the mammalian brain help filter distracting or disruptive signals — specifically from the hands — to coordinate dexterous movements. Their results may hold lessons in how the brain filters other sensory information as well.
Crewed Up China has unveiled the crew for its Shenzou 13 mission to the country’s brand new Tiangong space station, including the first female astronaut to venture to the outpost, the South China Morning Post reports . Wang Yaping will spend six months on board the space station — the country’s longest crewed mission to date — alongside astronauts Zhai Zhigang and Ye Guangfu. She could also becom
Eureka! Scott Pio, a Republican candidate for Virginia’s state legislature who wants to ban abortions and eradicate gun control regulations, may have come up with a solution for climate change that’s so brilliant that the rest of us literally can’t understand it. What if, Pio speculated on Twitter, we simply got rid of all the boats? “I’m curious,” Pio wrote in a since-deleted tweet that was grac
Air pollution is known to harm children's respiratory health, but its specific impacts on infection rates have remained unclear. A new analysis provides evidence of a link between the two in low-income settings, and indicates one industry may play an outsized role in the problem.
Laser treatment has the potential to transform the management of glaucoma in Africa, and to prevent more people from going irreversibly blind, particularly in regions with high disease prevalence and incidence, suggests new research. Conducted in Tanzania, the research is the first randomised controlled trial exploring the use of the laser treatment, Selective Laser Trabeculoplasty (SLT), for pati
For the second straight year, the world heads into a new La Nina weather event. This would tend to dry out parts of an already parched and fiery American West and boost an already busy Atlantic hurricane season.
For nearly 50 years, the incarceration rate in the U.S. has grown at an exponential rate. Today, the U.S. has the largest prison population in the world. Incarceration is especially common in poor communities of color where nearly 70% of Black men who did not finish high school and are approaching midlife will be in prison at some point in their lives.
Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or thei
Cadmium is an environmental pollutant and significant health hazard that is similar to the physiological metal zinc. In Caenorhabditis elegans, high zinc homeostasis is regulated by the high zinc activated nuclear receptor (HIZR-1) transcription factor. To define relationships between the responses to high zinc and cadmium, we analyzed transcription. Many…
Climate change–induced shifts in species phenology differ widely across trophic levels, which may lead to consumer–resource mismatches with cascading population and ecosystem consequences. Here, we examined the effects of different rainfall patterns (i.e., timing and amount) on the phenological asynchrony of population of a generalist herbivore and their food sources…
Deserts exert strong selection pressures on plants, but the underlying genomic drivers of ecological adaptation and subsequent speciation remain largely unknown. Here, we generated de novo genome assemblies and conducted population genomic analyses of the psammophytic genus Pugionium (Brassicaceae). Our results indicated that this bispecific genus had undergone an allopolyploid…
Reconstructing Cenozoic history of continental silicate weathering is crucial for understanding Earth’s carbon cycle and greenhouse history. The question of whether continental silicate weathering increased during the late Cenozoic, setting the stage for glacial cycles, has remained controversial for decades. Whereas numerous independent proxies of weathering in ocean sediments (e.g.,…
Nanoparticle (NP) stiffness has been shown to significantly impact circulation time and biodistribution in anticancer drug delivery. In particular, the relationship between particle stiffness and tumor accumulation and penetration in vivo is an important phenomenon to consider in optimizing NP-mediated tumor delivery. Layer-by-layer (LbL) NPs represent a promising class of…
Cooperative investments in social dilemmas can spontaneously diversify into stably coexisting high and low contributors in well-mixed populations. Here we extend the analysis to emerging diversity in (spatially) structured populations. Using pair approximation, we derive analytical expressions for the invasion fitness of rare mutants in structured populations, which then yields…
Inspired by the quest for shape-shifting structures in a range of applications, we show how to create morphable structural materials using a neutrally stable unit cell as a building block. This unit cell is a self-stressed hinged structure with a one-parameter family of morphing motions that are all energetically equivalent….
Selfish, non-long terminal repeat (non-LTR) retroelements and mobile group II introns encode reverse transcriptases (RTs) that can initiate DNA synthesis without substantial base pairing of primer and template. Biochemical characterization of these enzymes has been limited by recombinant expression challenges, hampering understanding of their properties and the possible exploitation of…
It is commonly believed that the energy bands of typical collinear antiferromagnets (AFs), which have zero net magnetization, are Kramers spin-degenerate. Kramers nondegeneracy is usually associated with a global time-reversal symmetry breaking (e.g., via ferromagnetism) or with a combination of spin–orbit interaction and broken spatial inversion symmetry. Recently, another type…
Infusing CRISPR/donor-loaded adeno-associated viral vectors (AAV/CRISPR) could enable in vivo hepatic gene editing to remedy hemophilia B (HB) with inherited deficiency of clotting factor IX (FIX). Yet, current regimens focus on correcting HB with simple mutations in the coding region of the F9, overlooking those carrying complicated mutations involving the…

Nature, Published online: 14 October 2021; doi:10.1038/d41586-021-02813-y The group, called SAGO, will create a permanent framework for probing epidemics, and initiate the next phase of the COVID origins hunt.
At the beginning of neurodegenerative disease, the immune cells of the brain — the 'microglia' — take up glucose, a sugar molecule, to a much greater extent than hitherto assumed. These results are of great significance for the interpretation of brain scans depicting the distribution of glucose in the brain. Furthermore, such image-based data could potentially serve as a biomarker to non-invasiv
Scientists from NASA’s Jet Propulsion Lab in California are projecting that humanity could become a multi-world species in a much shorter timeframe than one might think. And the clock is ticking, as the team argues in a preprint paper published in July. “Beginning with the development and deployment of the first nuclear weapons near the end of World War II, humanity entered a ‘Window of Peril’ wh
Known as a crucial component in the body's ability to absorb and retain calcium, essential to processes such as the development and maintenance of healthy bones, vitamin D has also been found to play important roles in immune defense. A new study in the October issue of the Journal of Dairy Science explores the effects of different sources and amounts of vitamin D in dairy cows, revealing promisin
The widespread flooding that submerged parts of the province's most densely populated regions in 2017 and 2019 exposed important gaps in Quebec's flood preparedness regime. With thousands of people displaced and hundreds of millions of dollars worth of damages incurred, the disasters spurred urgent re-investment in the aging system.
