Famous runestone in Sweden may have been erected for fear of extreme winter

The Rök rune stone, one of the most famous Viking rune stones in the world, has been analyzed again by a team of researchers who published the results in Futhark: International Journal of Runic Studies. This stone, which is located in a church in Östergötland, Sweden, was hoisted around 800 AD.

The most widespread thesis is that this stone, which boasts a mysterious inscription, never fully deciphered, was erected in honor of the dead son of an important personality. Some researchers have thought that the inscriptions may refer to the heroic acts of Theodoric the Great who was sovereign of the Ostrogoths during the sixth century in the area of modern Italy.

However, the new study, written by researchers from three different Swedish universities, suggests that the inscriptions refer to the danger of an imminent extreme winter and the fear of a repetition of a previous climate crisis that had seen extreme cold in Scandinavia in times before the erection of the stone. As the researchers explain, the inscription suggests an underlying anxiety that began following the death of a child but also the fear of a new climate crisis, something that these populations were evidently well aware of because in 536 A.D. there had been a catastrophic one.

It was during this period that there was an extreme cold caused by several volcanic eruptions. The winters saw very low average temperatures and this led, consequently, to poorer harvests and famine but also to mass extinctions in the animal world. It is estimated that during this period the population living in the Scandinavian area had been reduced by 50% and memories of this adverse event and extreme cold have evidently passed from generation to generation and never forgotten for centuries.

Moreover, when battles lasting more than 100 years are mentioned in the same inscription, according to the researchers we are referring not to real battles in the context of some war but to a different concept of battle, a sort of conflict between light and darkness, between heat and cold and therefore between life and death. Evidently in the period in which the stone was erected, there must have been some natural phenomenon that affected these populations, such as a powerful solar storm that saw the sky change color, a solar eclipse or an unusually cold summer with crops dying.

Only one of these events, as Bo Graslund, professor of archaeology at the University of Uppsala and one of the authors of the study, explains, could have triggered the necessary level of fear of a new “Fimbulwinter” (“great winter” in Norse mythology).

Quercetin may reduce blood pressure according to a new study

A plant substance, flavonoid quercetin, could be used to treat hypertension levels in patients. A team of researchers at Dongguan People’s Hospital Dongguan Shilong, China, said they found in a new study in Nutrition Reviews that quercetin itself can have a great impact on blood pressure. They also checked for possible effects on glucose levels.

Quercetin is a substance found in various plants, including food plants such as onions, apples or even in red wine and tea. It is a plant pigment that has already been the subject of several studies in the past. It is precisely these that the researchers analyzed: they compared 17 previous studies, which analyzed the effects of quercetin on a total of 886 participants, to find that this substance reduced systolic blood pressure.

The researchers also found that those who consumed quercetin for a period of eight weeks or more showed reduced levels of high-density lipoprotein cholesterol. However, the quercetin itself did not seem to particularly affect total cholesterol levels or fasting blood glucose concentrations.

Scientists are trying to measure its temperature of dark matter

A team of researchers at the University of California at Davis is trying to measure the temperature of dark matter, the imperceptible substance that should make up at least a quarter of everything in our universe.

Although we still don’t know what the dark matter is composed of, according to the researchers, it is possible to detect its temperature level. At least it is of this opinion Chris Fassnacht, a physics professor who, together with colleagues, is trying to analyze the distortion that happens when dark matter distorts light coming from distant objects. This is the effect called “gravitational lensing,” an effect that allows us to observe very distant objects in some cases otherwise imperceptible.

According to the standard model, dark matter should be “cold”, in the sense that it should be composed of particles that move relatively slowly, at least with respect to the speed of light. According to Fassnacht, however, this model does not work well on the scale of individual galaxies but only on the cosmic scale. Dark matter could be “hot”: the particles that compose it could be lighter and could move fast.

Analyzing the gravitational lens produced by seven distant quasars, the researchers examined the changes in the dark matter that produced the effect. The results showed a lower limit to the potential mass of a dark matter particle. This limit does not entirely exclude cold dark matter.

“We need to look at about 50 objects to get a good idea of how hot dark matter can be,” says the researcher, convinced that this study may be useful to understand the temperature level of dark matter.

North Atlantic current could stop for the next 100 years

The North Atlantic Current, a global climate phenomenon essential because it carries hot water from the Gulf of Mexico to Europe and the North Atlantic Ocean, could cease, albeit temporarily, during the next century according to a study published in Scientific Reports and carried out by researchers at the Universities of Groningen and Utrecht.

This current, or rather a complex system of currents in the Atlantic Ocean, causes a phenomenon defined as “southern overturning circulation” (AMOC), a phenomenon that guarantees an almost mild climate for most of north-western Europe, transporting southern heat to the North. The phenomenon could come to a halt due to the sea water that could increase as a result of the melting of Greenland ice as well as possible increased rainfall.

Already in the period between 2008 and 2012 the average strength of the AMOC decreased compared to the period 2004-2008 and there was a short interval at the end of 2009 when its strength was almost zero. According to the researchers, AMOC’s strength could be sensitive to the presence of surface fresh water. Researchers have carried out simulations of large freshwater inputs into seawater, which is what is expected to happen during the coming decades with the Greenland meltdown, and have found that there is a 15% probability that during the next century this current could stop, or almost completely, temporarily.

Researcher Daniele Castellana of the University of Utrecht, one of the authors of the study, states: “The temporary interruptions of the North Atlantic current are to be interpreted as fluctuations of the same current. The consequences of these fluctuations on the climate of Europe and North America have not been analyzed by the study, and there is no (yet) evidence to affirm a correlation between the two phenomena. Substantial temperature variations have been found, by other studies, as the potential consequence of a permanent stop of the Atlantic currents. Such a permanent stop, however, seems to be very unlikely in the next 100 years, as our study states.”

In essence, any climate change in the North Atlantic Ocean and continents with decreases in temperature and possible waves of frost as a result of temporary stops in the current must be substantiated by further studies.

Life on earth perhaps emerged thanks to lakes rich in phosphorus

Life on Earth may have originated in carbonate-rich lakes with high levels of phosphorus, an essential element for life as we know it. This is the conclusion of a new study conducted by two researchers from the Department of Earth and Space Sciences at the University of Washington, Seattle, Jonathan Toner and David Catling.

Toner himself speaks of a real “phosphate problem”, a question not fully resolved with regard to the very origin of life on our planet. In the new study, published in Proceedings of the National Academy of Sciences, attention is therefore drawn to phosphorus, one of the six chemical elements at the basis of life that can have many essential roles in our body (for example it can be considered a basic element of the backbone and molecules of DNA and RNA).

The problem mentioned by Toner lies in the fact that life needs a lot of phosphorus, an element that in the primordial Earth, according to the dominant theories, should not be so available. Focusing, however, on lakes rich in carbonates, also known as alkaline lakes, researchers have noticed a particular phenomenon: these lakes usually form in dry environments, inside real depressions that help the water to escape. However, due to the high evaporation rates, these same waters begin to become very salty from alkaline and to assume a high pH. These lakes are currently still very widespread around the world.

Researchers have carried out laboratory experiments with carbonate-rich water in different chemical compositions and found that these waters show a high presence of phosphorus precisely because of carbonate. Carbonate binds with calcium, leaving part of the phosphate unattached and freely available in the water. A fairly simple idea but still fascinating, as Toner himself suggests.

According to David Catling, the other author of the study, these very high levels of phosphate in lakes and ponds would then have favored the reactions that led phosphorus to be the basis of RNA, proteins and fats, basic elements for life.
These lakes, then, in the period of origin of life, about 4 billion years ago, would have been very numerous also because of the high level of carbon dioxide in the air. In addition, carbon dioxide itself tends to dissolve in water, raising the level of acidity and promoting the release of phosphorus from the rocks, increasing the presence of this element.

This was not a rare phenomenon since the primitive Earth was volcanically very active and therefore fresh volcanic rock tended to react with carbon dioxide increasing the presence of carbonate and phosphorus in the lakes, as Toner himself makes clear that in the primordial Earth lakes rich in carbonates were not at all an exception but the rule.

Aircraft emissions have impacts on air quality even greater than those they have on the climate

A new study, produced by MIT researchers and published in Environmental Research Letters, shows that the impact of aircraft on air quality is even more serious than the impact they have on the climate. Specifically, the researchers found that the same aviation sector, now in continuous growth, is the cause of at least twice the damage to air quality compared to damage to the climate.

According to Sebastian Eastham, a researcher at the Laboratory for Aviation and the Environment in the MIT Department of Aeronautics and Astronautics, the emissions caused by air transport represent one of the most important factors with regard to man-made climate change, a factor that can be calculated at a level of 5%.

Considering the entire flight, which also includes the take-off and landing phases, the same emissions produced by the aircraft are responsible for at least 16,000 premature deaths a year due to air pollution. This is 0.4% of the total deaths caused by air quality, a figure that almost always is not considered at all when analyzing air pollution.

As for possible solutions, the same researchers admit that reducing a type of emissions then almost automatically leads to the increase of another type.

“We could reduce NOx emissions by designing engines with lower combustor temperatures. However, the resulting loss of thermodynamic efficiency would mean that we need to burn more fuel, or more CO2. These are the types of compromises that need to be quantified and our study offers a quick way for those who have to make decisions to do so.”

Following the analysis they carried out, the researchers found that reducing CO2 emissions and aircraft contrails did not achieve the greatest net climate benefit. On the contrary, reducing NOx emissions during the flight would bring the greatest net benefits. Furthermore, the researchers concluded that aircraft emissions and air transport, in general, have an impact on air quality greater than the impact they have on the climate, an impact that is 1.7 to 4.4 times higher.

Children of older female mice more prone to heart problems

Particular changes in the placenta of older females can lead to heart problems in older sons according to a study, published in Scientific Reports, conducted on rats. The researchers discovered differences defined in the press release as “significant” regarding the development and growth of the fetus and its connection with the placenta according to its sex.

The researchers carried out experiments with pregnant female rats aged 3-4 months or 9.5-10 months. Older females had an age which, according to the researchers, may correspond to a human age of about 35 years which is considered a sort of “limit” beyond which one begins already to speak of “advanced maternal age.” The researchers found that for sons born to older mothers there were more likely to be heart problems and hypertension.

While with female fetuses the placenta showed no particularly negative changes in its structure and in its function, and in some cases, the same placenta provided more benefit to female fetuses in cases of older mothers than younger mothers. With male fetuses, this did not happen and the same changes in the placenta seemed to limit the growth of the fetus.

These findings could lead to “better management of human pregnancies and the development of targeted interventions to improve the long-term health of children born to older mothers,” explains Tina Napso, a Cambridge University researcher and one of the authors of the study.

This further study shows that the pregnancy of older mothers is more at risk than the pregnancy of younger mothers not only for the mother herself but also for the baby.

As Amanda Sferruzzi-Perri, researcher at the Center for Trophoblast Research at the same English university, explains, “With the average age of first pregnancy in women becoming ever higher, and especially in developed countries, it is very important to understand how age interacts of the mother and the sex of the child to determine the child’s pregnancy and health in old age.”

Marshes can save the world from ongoing climate change

Marshes could save the world: this is the conclusion reached in an article published in Horizon Magazine according to which peat bogs, swamps with a large abundance of slow-moving water at low temperatures, can represent an “excellent” deposit for carbon dioxide.

Carbon dioxide is one of the most powerful and most capable of changing the earth’s climate and it is important to “sequester” it or store it so that it is not lost to the environment. There are many methods that scientists are devising to achieve this goal but more and more often we resort to the same nature that has already shown that it can perform this task perhaps even more efficiently than any method developed in the laboratory. Among the many types of natural environments that can “sequester” carbon dioxide there are also marshes: peat bogs, made mostly of decaying dead plant material, can cause carbon dioxide to deposit under this layer.

The plant material is usually broken down by the enzymes that are in turn present in the microorganisms. In peat bogs, however, there are also other compounds called phenols that stop the functioning of some of these sets and lead to a “spectacular failure of decomposition,” as Chris Freeman, biogeochemist of Bangor University, UK, explains, who is studying the swamps and their ability to store carbon dioxide. This is a somewhat precarious equilibrium: it would suffice for only one of these enzymes, called phenol oxidase, to come into action because the decomposition process starts again and the peat bogs begin to release their carbon into the environment. It is, as defined in the press release, a “delicate standstill that holds the door to climate disaster.”

Now scientists fear that this can happen with global warming and with the ever more pressing drought and for this very reason Freeman himself, together with researcher Juanita Mora-Gomez, now at the Earth Sciences Institute of Orléans, have started a new project called microPEAT to study the bogs of Wales, the Arctic and Colombia with much more detail. They took samples from these swamps and brought them to the laboratory to subject them to pressing drought conditions and to understand the resulting effects.

In fact, what was feared happened with the champions of Wales and the Arctic: with drought, the microbes in the peat changed their metabolism and began to emit carbon. However, with the Colombian champions, the same state of drought went instead to further suppress the phenoloxidase enzymes. Researchers want to understand the reason for this differentiation but already believe that there are some particular points in the peat bogs that may be more resistant to climate change than others.

Answering these questions could be very important to prevent the release of carbon into the environment and therefore the acceleration of global warming. This is a “very important possibility,” as Freeman himself explains, a sort of “plan B for the planet.”

Experimental HIV vaccine successfully elicits antibodies that neutralize viruses in rabbits

Research for the development of a truly effective vaccine for HIV continues. A new study, this time conducted by the scientists of the Scripps Research Institute and published on Immunity describes the results that the same researchers have obtained with an experimental vaccine, results that have led to “an important milestone.” It is a vaccine that urges antibodies so that they can neutralize a wide variety of HIV strains.

For now, tests have been carried out on rabbits but the same antibodies have proven to be “largely neutralizing” when they targeted at least two critical virus sites. These results give researchers hope for the development of a new, effective HIV vaccine, a vaccine that can elicit neutralizing antibodies at multiple HIV sites to provide a solid production against this virus.

“It is an initial principle test but important, and we are now working to optimize the design of this vaccine,” says Richard Wyatt, professor of immunology and microbiology at Scripps as well as one of the authors of the study. The new vaccine is based on a protein that mimics HIV protein called “Env.” In fact, this protein boasts a molecular mechanism that allows it to bind to an immune cell receptor known as CD4. This receptor can be used as a “portal” to break into the cell.

The Env version designed by researchers is stable enough to be used as a vaccine, at least on rabbits. Out of 12 animals with HIV on which this particular protein was inoculated, five developed antibodies that could neutralize more HIV isolates.
