UK-based team finds antibodies peaked higher after fourth jab given after gap of more than six months than after third A fourth dose of a Covid vaccine can ramp up the body's immune defences beyond the peak achieved after a third dose, research suggests. A second booster – often a fourth dose of a Covid vaccine – is currently offered in the UK to those aged 75 or over , people living in care home
Sweet Space The James Webb Space Telescope is almost ready for scientific observations to begin. NASA's largest most powerful telescope ever built just captured a gigantic image of a neighboring galaxy and beamed it back to Earth as it settles into its new, deep space home. The Associated Press reported today that the $10 billion telescope should begin gathering scientific images in July. In the
Intensive parenting—the dominant model of modern American child-rearing—is a bit like smoking: The evidence shows that it's unhealthy, yet the addiction can be hard to kick. I'd like to suggest strategies that could help society quit overparenting, and they require parents, policy makers, and even the childless to pitch in. But first, we need to understand why intensive parenting—whereby mothers
NASA's InSight Mars lander has detected the largest quake ever observed on another planet: an estimated magnitude 5 temblor that occurred on May 4, 2022, the 1,222nd Martian day, or sol, of the mission. This adds to the catalog of more than 1,313 quakes InSight has detected since landing on Mars in November 2018. The largest previously recorded quake was an estimated magnitude 4.2 detected Aug. 25

Crash and Burn Bitcoin is down horrendously — and it's losing money for many investors who thought it was a sure shot during balmier days. According to a new analysis from crypto analysis firm Glassnode , roughly 40 percent of Bitcoin holders have lost money on the world's most popular cryptocurrency. And that percentage is likely higher for those who invested over the past few years, when the cu
Bill Gates is reading the signs, and he says they don't point in a positive direction for the global economy. In an interview with CNN , Gates said he was worried about rising inflation. The billionaire investor and Microsoft cofounder said government debt levels were high before the pandemic, which then caused dramatic supply chain shortages that only made the economy worse. "It's likely to acce
In 2017, Roger Guimerà and Marta Sales-Pardo discovered a cause of cell division, the process driving the growth of living beings. But they couldn't immediately reveal how they learned the answer. The researchers hadn't spotted the crucial pattern in their data themselves. Rather, an unpublished invention of theirs — a digital assistant they called the "machine scientist" — had handed it to them.
A fter the Supreme Court's stunning leak last week, it is finally dawning on the public that Dobbs v. Jackson Women's Health Organization will likely mark the end of constitutional protections for abortion rights. The Court's decision to take up the case, coupled with its failure to even temporarily protect Texas women from an unconstitutional post-six-week abortion ban last fall, clearly signale

Just an hour before Russian troops invaded Ukraine, Russian government hackers targeted the American satellite company Viasat, officials from the US, EU, and UK said today. The operation resulted in an immediate and significant loss of communication in the earliest days of the war for the Ukrainian military, which relied on Viasat's services for command and control of the country's armed forces.
It looks like a few employers may be the last hope for those that need reproductive healthcare. Last Monday, Politico broke the news that the US Supreme Court was likely to overturn Roe v. Wade. That landmark 1973 ruling, of course, gave people the constitutional right to get an abortion, and has been legal precedent for nearly five decades. And because this cultural moment often encourages compa

A new University of Michigan study that used fossil oyster shells as paleothermometers found the shallow sea that covered much of western North America 95 million years ago was as warm as today's tropics.
Despite the effectiveness of vaccination campaigns worldwide, the threat posed by COVID-19 still exists. First of all, a new SARS-CoV-2 variant could very well emerge that may not respond to current vaccines. Secondly, the efficacy of the vaccines in the long term remains unknown. Lastly, cases of acute infection are continuing to be reported. And yet, there is no effective treatment to date.
Humans are undoubtedly altering the natural environment. But how wild animals respond to these changes is complex and unclear. In a new study published today, scientists have discovered significant differences in how the brain works in two distinct personality types: those who act fearless and those who seem afraid of new things.

The best shower speakers are water-resistant, will easily link up to your smartphone via Bluetooth, and have great sound
Researchers are closer than ever to pinning down the date of the infamous Thera volcano eruption. A new study combines a mosaic of techniques to confirm the source of a volcanic eruption in 1628 BCE. While the eruption was previously thought to be Thera on the Greek island of Santorini, Charlotte Pearson, an associate professor in the Laboratory of Tree-Ring Research at the University of Arizona,
Our stories about environmental catastrophe used to be set in distant futures: the desolate endlessness of The Road , or the hopeless, cutthroat scrounging in the Parable of the Sower . But that kind of far-off storytelling feels like it was made for a time when the repercussions of changing climate and the inequity of natural-resource use were, in fact, far off. Must have been nice. Ecological d
Researchers have discovered that before cells start to divide, they toss waste products. Using a new method they developed for measuring the dry mass of cells, the researchers found cells suddenly lose mass as they enter cell division.
Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.
Settling a key dispute in the wireless communications field, researchers found that transmission performance is consistent across different bands of the millimeter-wave (mmWave) spectrum targeted for high-speed, data-rich 5G systems.
Scientists describe their work on an at-home study of rheology, which is used to study the way non-Newtonian liquids or semisolid substances flow. The projects assigned to students had two parts: gathering qualitative visual evidence of rheological properties and taking quantitative measurements. The students checked for four behaviors — shear thinning viscosity, viscoelasticity, shear normal str
Researchers present clinicians with information about the risk factors for atherosclerotic plaque formation from a mechanical point of view. The scientists are exploring whether it is possible to screen and intervene early for people at risk for atherosclerotic disease from the perspective of hemodynamics, using color Doppler ultrasound, coronary computed tomography angiography, and other screenin
Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a new study. The results lead directly to the idea that modifying the diet has the potential to be a new weapon in the fight against antimicrobial resistance. And this does not require eating some exotic diet, but eating a diverse diet, adequate
Researchers found that less than half of Americans who received treatment for opioid use disorder over a five-year period were offered a potentially lifesaving medication. The numbers were even lower for those with what's known as polysubstance use disorder — when opioid users also misuse other substances.
Researchers show that cancer cells in an acidic environment undergo lipid synthesis and accumulation. The team identified the key signaling molecules responsible for these changes and discovered that these alterations are associated with poor outcomes and disease progression among breast cancer patients.
Tumors can force neighboring cells into supporting cancer growth by releasing lactate into their local environment, according to researchers. The findings pave the way for future drug treatments that thwart that defense mechanism to help cancer patients.
According to the latest report of the Intergovernmental Panel on Climate Change (IPCC), almost half the world's population—about 3.3 billion to 3.6 billion people—live in contexts that are highly vulnerable to the impact of climate change. Social inequality greatly increases this vulnerability.
The World Cycling Championships in Bergen in 2017 had budgeted slightly more than €16.5 million in both revenues and costs. They missed the mark on both counts, and the event incurred a € 5.8 million deficit.
"From my own knowledge of these things, physics is not something that girls tend to fancy. They don't want to do it … There's a lot of hard math in there that I think that they would rather not do," Katharine Birbalsingh, chair of the U.K. government's Social Mobility Commission and a secondary school head teacher, told the Commons Science and Technology Committee on April 27 2022.
Primordial germ cells (PGCs) are the first germ-cell population established during development. The survival of species is dependent upon PGCs in sexually reproducing organisms because they are the founder cells for the germline.
When we think of tools to achieve climate goals such as limiting the average temperature increase to 1.5 degrees above that of the pre-industrial age, most of us visualize wind turbines, solar panels and electric cars. Even the climate policy models currently in use, the so-called Integrated Assessment Models (IAMs), which aim to borrow and combine insights from climate science, engineering, and e
When industrial effluents containing high levels of heavy metals are discharged into fish bodies, they pose a serious threat to aquatic ecosystems. One such heavy metal, zinc, is required by organisms in miniscule amounts, but if it accumulates in higher concentrations, zinc can trigger oxidative stress in the fish body. This causes metabolic, physiological, and cellular damage, including protein
The war in Ukraine, the COVID-19 pandemic, and climate change have halted food production worldwide and have led to large price increases that are affecting average families, says David Ortega. Ortega is a food economist and associate professor in the agricultural food and resource economics department at Michigan State University. Watch Ortega explain what's behind the rise in food prices below:
It's always rewarding when what started out as largely an academic endeavor turns out to impact a lot of people — in this case women. Women suffering from endometriosis, polycystic ovary syndrome (PCOS) and preeclampsia may be protected from future heart disease if they carry a specific common genetic variant on the surface of cells (insulin-like growth factor-1 receptor, or IGF1R).

According to estimates, by 2040 the level of plastic pollution could reach 80 million metric tons per year. Plastic particles have now been detected in virtually all spheres of the environment, e.g. in water bodies, the soil and the air. Via ocean currents and rivers, the tiny plastic particles can even reach the Arctic, Antarctic or ocean depths. A new overview study has now shown that wind, too,
When genes mutate, this can lead to severe diseases of the human nervous system. Researchers have now used fruit flies to demonstrate how, apart from the negative effect, the mutation of a neuronal gene can have a positive effect — namely higher IQ in humans.
Childbirth in humans is much more complex and painful than in great apes. It was long believed that this was a result of humans' larger brains and the narrow dimensions of the mother's pelvis. Researchers have now used 3D simulations to show that childbirth was also a highly complex process in early hominins that gave birth to relatively small-brained newborns — with important implications for th
In farming areas across Calfornia's Central Valley, a well-drilling frenzy has accelerated over the last year as growers turn to pumping more groundwater during the drought, even as falling water levels leave hundreds of nearby homes with dry wells.
As society continues to emerge from COVID-19 into a recovery economy, questions about the future of care also emerge. In Canada, the pandemic revealed existing problems with the care economy such as the poor conditions in long-term care homes and the dearth of affordable and high-quality early childhood education as well as the low pay and poor working care workers face on a daily basis.
Modifying photosynthesis has increasingly been a research target to improve crop yields to feed a growing global population in the face of climate change and other environmental factors.

Distant galaxies, dark matter, dark energy and the origin and evolution of the universe itself are some of the many scientific goals of China's newly announced space telescope. If all goes according to plan, the China Space Station Telescope (CSST) will blast off atop a Long March 5B rocket sometime in late 2023. Once in a safe orbit, CSST should begin observations in 2024. Judging by these resear
Fruit flies synchronize the movements of their heads and bodies to stabilize their vision and fly effectively, according to Penn State researchers who utilized virtual-reality flight simulators. The finding appears to hold true in primates and other animals, the researchers say, indicating that animals evolved to move their eyes and bodies independently to conserve energy and improve performance.
The two mountains theory and its slogan, "lucid waters and lush mountains are invaluable assets," have been promoted in China for 15 years. This slogan aims to increase social perception of ecosystem services, promote the achievement of sustainable development goals, and has increased individual knowledge and awareness of environmental conservation under local community policy initiatives.
A study by the UPV/EHU-University of the Basque Country into the paleodiet of extinct paleotheriidae (or pseudo horses) provides information about their feeding strategy and the environment they inhabited at the end of the Eocene. Plagiolophus was a highly selective perissodactyl and fed on tough foliage.
Ribonucleic acids (RNAs), which decode the genetic code stored in DNA and produce proteins, fold into diverse structures to govern fundamental biological processes in all life forms, including humans. Targeting disease-associated RNA structures with drug-like small molecules has been one of the gold standards for developing RNA-targeting drugs in the scientific field. Recently, a research team has
Researchers have mapped how the parasite Trypanosoma cruzi forms new variants that are more effective at evading the immune system and causing disease. Their findings can give rise to new methods for diagnosing, preventing and treating Chagas disease, which affects millions of people in Central and South America, causing thousands of deaths every year.
Malnutrition in developing countries is best addressed not by increasing the variety of crops grown on smallholder farms, but by improving access to markets. More variety in animal production, however, does show positive effects.
Much of what scientists think about soil metabolism may be wrong. New evidence suggests that microbes in different soils use different biochemical pathways to process nutrients, respire, and grow. The study upends long-held assumptions in the field of soil ecology and calls for more investigation and higher-resolution methods to be applied to what has been a black box for the field.
A new study used machine learning to classify infants as either male or female at 0-24 weeks of age, 24-48 weeks of age and older than 48 weeks based off 14 temperament dimensions. Accuracy rates increased with age, ranging from a low of 38% for age group one, to 57% for age group three.
Researchers have conducted the first assessment of metabolites in African savanna elephants, an important step in understanding the relationship between metabolism and health in these endangered animals.
The Number One confounding factor in animal research is the person conducting the experiment. Behavioral biologists examined this factor in behavioral experiments involving mice at different locations.
Printers act as a link between the digital and physical worlds. Documents, webpages, and photos that start on your phone, computer, or tablet, end up on a slice of paper you can hold in your hands. If you've ever been frustrated by a printer — beyond the fact that toner is somehow the most expensive substance on Earth — it's because this transmutation from digital to physical is really hard. For

A new study finds higher incidence of lung cancer and brain tumors in people exposed to wildfires. The study, which tracks over two million Canadians over a period of 20 years, is the first to examine how proximity to forest fires may influence cancer risk.
Individual traits seem to drive our learning success: for instance, conscientious individuals often show higher academic performance. A group of cognitive and behavioral biologists conducted personality assessments and a battery of learning tests with common marmosets and found that such a link, intertwined with family group membership, exists in these monkeys, too.
There are 600 million women in India — yet they are rarely seen outdoors after sunset because of safety concerns like harassment and catcalls. On a mission to create safer public spaces, women's rights advocate Srishti Bakshi talks about how she embarked on a 2,300-mile walk across the length of India (a distance equivalent to traveling from New York City to Los Angeles), conducting driving works
The social media messages that resonate best with loyalty program members differ from the posts that work best with other customers, research shows. The finding could inform how best to craft social media campaigns aimed at either segment of a company's customer base. "Loyalty programs and social media are both important tools in contemporary marketing, but there's very little research into how t
Chronic poverty in the developing world can seem like an insoluble problem. But a long-term study from Bangladesh co-authored by an MIT economist presents a very different picture: When rural poor people get a one-time capital boost, it helps them accumulate assets, find better occupations, and climb out of poverty.
In Finland, climate change is causing the pine pest Panolis flammea, or pine beauty moth, to shift its range northward 50 years ahead of predictions. Changes in both the distribution and size of the pine beauty moth population are linked to higher temperatures, a new study from the University of Eastern Finland shows. The findings were reported in the Scandinavian Journal of Forest Research.

When Dr. Jessica Little laid eyes on the 56-year-old man, Mr. M, she immediately knew he was in bad shape. Striking, painful red welts dotted his entire arm. He knew the cause of his rashes: an infection by Mycobacterium chelonae, a bacteria that eats away at the skin and soft tissue. Yet despite multiple antibiotic treatments over six months, his arm continued to disintegrate. Even worse, the an

A bacteria called Staphylococcus aureus is widespread and generally harmless, but can cause infections known as "opportunistic infections." These occur when the bacteria take advantage of certain situations, such as a weakened immune system or the presence of an open wound, to cause a harmful infection. These infections become particularly dangerous when the bacterial strain is resistant to treatm
North Carolina State University researchers have conducted the first assessment of metabolites in African savanna elephants (Loxodonta africana), an important step in understanding the relationship between metabolism and health in these endangered animals.
Trace gas sensing is critical for monitoring environmental pollution and detecting volatile organic compounds released from the human body. As a powerful analytical tool for identifying trace molecules, surface-enhanced Raman spectroscopy (SERS) enables remarkable amplification of normal Raman signals by using the surface plasmon resonance effect and charge-transfer effect with excellent sensitivi

A team of researchers affiliated with several institutions in China and the U.S. has found evidence that suggests three distantly related types of mushrooms gained their ability to produce a dangerous toxin via horizontal gene transfer sometime in their past. In their paper published in Proceedings of the National Academy of Sciences, the group describes their genetic analysis of multiple species
A suite of complementary tests can quantify changes in dogs suspected of having cognitive decline, report researchers. The approach could not only aid owners in managing their elderly canine's care, but also serve as a model for evaluating cognitive decline progression in—and treatments for—humans with Alzheimer's disease. Canine cognitive dysfunction syndrome (CCDS) is similar to Alzheimer's dis
Credibility labels don't shift news diets away from low-quality sources or reduce belief in widely circulated inaccurate claims among average internet users, research finds. The findings do indicate that providing an indicator of sources' quality may improve the news diet quality of the heaviest consumers of misinformation, however. Notably, the researchers also found that a majority of people re

Shredded recycled plastic pieces on display at the Minnesota State Fair. The accumulation of plastics in the environment is a problem that won't solve itself, at least not on any time scale relevant to humanity. These materials are designed to be durable and long-lasting, and current methods of recycling barely put a dent in the mountains of plastic produced every year. Researchers from the Unive

New research has pinpointed four high-traffic areas in the Pacific Ocean that should be considered of high priority if conservation efforts focused on large pelagic fishes such as tuna, blue marlin and swordfish are to be successful.
In a world of materials that normally expand upon heating, one that shrinks along one 3-D axis while expanding along another stands out. That's especially true when the unusual shrinkage is linked to a property important for thermoelectric devices, which convert heat to electricity or electricity to heat.
Some period-tracking apps share data with third parties. With the potential rolling back of abortion protections in the US, people are reassessing if the data collected by these apps could be used as evidence against them
Imagine being able to measure your blood sugar levels, know if you've had too much to drink, and track your fatigue during a workout, all in one small device worn on your skin. Engineers developed a prototype of such a wearable that continuously monitors several health stats at once.
Here my thoughts: On the first question: as the AGI will have been trained with huge data sets of all kinds of information from the internet i.e. from humanity, would it not anyway argue in the same way as a self-aware human would argue and therefore pass also the ACT consciousness test without being necessarily actually conscious? On the second: given that the training data sets of the AGI will
