Wormholes would have been discovered by now

Currently only hypothetical, wormholes are conceptually a tunnel in space-time that connects two distant points in the universe. However, a team of astrophysicists from the University of Sofia, Bulgaria, claims in a study published in the journal Physical Review D. that such wormholes may be a reality. And not only that, we would have already discovered them.

The Bulgarian researchers started from an idea expressed since the 1930s, namely that the distortion of space-time caused by a black hole could, at least hypothetically, be connected to a white hole, thus forming a tunnel cosmos.

To demonstrate the reliability of such a model, astrophysicists from Sofia created a simplified model of such an interstellar “bridge” in the laboratory. Specifically, they created a magnetized fluid vortex and watched the matter move before it was swallowed by it.

Thus, particles captured by this “vortex” will create electromagnetic fields that will act in predictable patterns, polarizing the light emitted by the heated material. In fact, Bulgarian experts say, it was polarized radio waves that allowed us to observe the black hole M87 in 2019 and Sagittarius A, the massive black hole at the center of the Milky Way, in 2022.

In short, the polarized light emitted by the wormhole will be very difficult to distinguish from the light around the black hole. And by this logic, for example, M87 may well be a wormhole. Obviously, all these observations remain, at least for the time being, at the stage of speculation, but the study of the Bulgarian researchers can only be the beginning of in-depth studies of this phenomenon.

The earliest evidence of the use of fire for cooking was found in Israel

The remains of a giant carp about two meters long, discovered at the Gesher Benot Yaakov archaeological site, show the earliest traces associated with the use of fire for cooking, a group of Israeli archaeologists reported in a study. published in the journal Nature Ecology and Evolution. Until now, the earliest evidence of the use of fire for this purpose was about 170,000 years old, but those discovered in Israel exceed that date by more than 600,000 years. In particular, the osteological remains showed an age of 780,000 years.

Numerous fish fossils were found at the site, which testifies not only to the ability of hominids of that time to use fire for cooking, but also to their ability to catch large numbers of fish, even large specimens. In addition, isotopic analysis of fossils shows that their catch was not seasonal, but permanent. In fact, it is hypothesized that this type of diet, rich in omega-3s, contributed to brain development in ancient human species.

Researchers have analyzed the teeth of a Siamese carp (Catlocarpio siamensis) caught 780,000 years ago and found evidence that the teeth of the Siamese carp (Catlocarpio siamensis) were exposed to high temperatures for cooking, rather than spontaneous, sustained fire. Crystals that form on the enamel of the teeth during exposure to high temperatures indicate that this fish was not thrown into the fire, but, most likely, was placed on a stand so that it would not burn during the cooking process.

Artifacts characteristic of the Acheulean culture, a culture associated with individuals of the species Homo erectus, were discovered in connection with the fossil remains of fish. The next step, according to Israeli experts, is to find traces that indicate that the use of fire for cooking was not limited to fish, but could also extend to cooking plants or other animal products.

Over the past 50 years, the average lifespan of bees has decreased by 50%.

As they tried to respond to the problems reported by US beekeepers; accordingly, the loss of bees and the decrease in the amount of honey produced by them, a group of entomologists from the University of Maryland discovered an alarming fact. In particular, the average lifespan of bees has decreased by 50% compared to 50 years ago.

Worse, experts don’t know exactly what caused the decline, from 34.3 days as the average life expectancy of a bee in 1970 to 17.7 days today. Hypotheses involving pesticides, parasites, environmental factors, disease, or diet were eliminated one by one. These factors do not seem to have affected the bees enough to cut their life spans in half. At least, this is according to a study published in the journal Scientific Reports.

Rather, according to American researchers, the genetic factor is to blame. If they are right, then this hypothesis has a positive side. Accordingly, genes responsible for reduced longevity can be isolated to return bees to normal life.

But the research is in its early stages, and entomologists will have to correlate data from the US and other countries, and the results will pinpoint the real reasons for the decline in the average life expectancy of bees.

Brazil, Indonesia and DR Congo have signed an agreement to end deforestation

On the occasion of the UN climate change conference, COP 27, the countries with the largest areas of tropical forests, Brazil, Indonesia and the Democratic Republic of Congo, announced that they will join forces to stop deforestation and preserve forested areas. The agreement provides that the countries involved will receive compensation from the international community to compensate for the financial losses caused by the significant reduction in deforested areas.

Brazil’s new president, Luiz Inacio Lula da Silva, has already set about correcting former president Jair Bolsonaro’s policies of deforestation and agricultural expansion in the Amazon basin. As for the DR Congo, officials there have recently been criticized for expanding oil activities in sensitive areas of the Congolese rainforest, but they have stressed that these issues are purely a matter of state economic policy.

Despite this, the Congolese authorities have taken measures to protect forest areas against the backdrop of problems caused by rising global temperatures. Similar promises have been made in recent decades. Whether this time there will be more than promised, we will find out in the coming years.
