NASA has discovered the “arm of a giant skeleton” in deep space

In the nebula MSH 15-52 at a distance of more than 16 thousand light years can be seen a strange cosmic spectacle resembling the arm of a giant skeleton. American aerospace agency recorded this phenomenon after 17 days of continuous focusing of the most technologically advanced telescope IXPE, using X-ray beams. The ghostly hand, according to scientists, represents clusters of energetic particles emitted by neutron pulsar stars.

Charged particles generating X-rays propagate predominantly along magnetic field lines and determine the shape of the formed nebula. In this case, the strong magnetic fields are distributed in such a way that the final image in the X-ray spectrum looks like the arm of a ghostly skeleton.

A flat Earth is not a myth, but a very likely past of our planet

As explained by Dr Dimitris Stamatellos, in modelling the formation of cosmic bodies, scientists have always defaulted to the idea that the accumulation of matter occurs in the form of a sphere. In this case, the very process of attraction to each other particles of dust and dirt from interstellar space proceeds very unevenly. Researchers used modelling with the help of a supercomputer to test various hypotheses.

Scientists have revealed the first cases of Alzheimer’s disease infection

Specialists have reported a number of cases in which Alzheimer’s disease developed as a result of medical intervention that occurred long before the patients showed the first signs of the disease. Thus, the disease developed as a result of transmission of a pathogenic form of the relevant proteins.

The research paper looked at eight patients who underwent cadaveric growth hormone therapy during childhood. The subjects ranged in age from 38 to 55 years old. Five of them had symptoms of dementia and had already been diagnosed with Alzheimer’s disease. Another patient was matched for the disease by a constellation of cognitive impairments.

Scientists beat the temperature inside the Chicxulub crater after the dinosaur-killing asteroid hit

The work of scientists states that the samples of stones obtained from the crater reached sizzling 330 degrees centigrade, this happened at the end of the Cretaceous period. In addition, in their study, experts found that the fall of the asteroid was not as large amount of carbon dioxide was released as previously believed by scientists, and this may change the view of the scientific community on the mass extinction triggered by the asteroid.

A new method of determining a person’s geolocation by gadget has been created

by Mia Harris

written by Mia Harris

So, now the location of a certain user connected to the network can be determined by triangulation, but this requires at least 3 cellular stations to which the phone is connected.

Specialists reported the development of a station that is able to independently determine the geolocation of a certain smartphone.

As noted by experts, a router has been created that uses 5G and WiFi 7 standards, which operate at frequencies above 20 GHz. The station detects the gadget and measures the distance to it by sending signals. The more distant a person is from the station, the longer the signal stays on the air, the experts specified.

Stratospheric dehydration may prove to be an effective way to combat climate change

by Mia Harris

It is noted that water vapour in the stratosphere forms a barrier that prevents heat from the Earth’s surface from escaping into space. In their work, scientists have considered the prospect of dehydration of this layer of the atmosphere in order to cool our heating planet.

Experts from the US National Oceanic and Atmospheric Administration (NOAA) pointed out that most of the air enters the stratosphere in the tropics.

Archaeologists have found mysterious stone circles built before the Egyptian pyramids

by Mia Harris

written by Mia Harris

Scientists have discovered mysterious stone circles in the Andes, which apparently were erected before the pyramid complex in Egypt.

The stone structure, which has a diameter of just over 18 metres, consists of two concentric walls made of unformed stone exposed vertically on the ground. It is noted that the monument in question is located at the archaeological site of Callacpuma in the northern part of Peru’s Cajamarca Basin, located three kilometres above sea level near the summit of a peak in the Andes, the world’s largest mountain range.

A toad from Brazil could be recognised as the smallest amphibian on Earth

by Mia Harris

written by Mia Harris

Experts estimate that the body length of these tiny amphibians is only 7.1 millimetres. Until now, the scientific community believed that the smallest dimensions among amphibians have the smallest dimensions among amphibians inhabiting New Guinea narrow-mouths belonging to the species Paedophryne amauensis – 7.7 millimetres long.

It is noted that the new candidate for the place of the smallest amphibian was presented by specialists from the University of California State University in Santa Cruz. The description of this species, made back in 2011, indicated that its length can reach 8.2 millimetres, but it was not known whether there is a difference in size between females and males.

It turns out that octopuses can experience “heartache”

by Mia Harris

written by Mia Harris

Past experiments by Kruk and other researchers have demonstrated the ability of cephalopods to produce a reflexive response to stimuli by learning not to make contact with them. The fresh experiment went further. After training in a 3-chamber box, clams that had been injected with acetic acid in their tentacle no longer swam into the chamber in which it happened. And those injected with normal saline did not produce a similar reaction.

Next, the cephalopods who received the painful injection were injected with an anaesthetic, and they subsequently preferred to stay in the chamber in which they felt rapid pain relief. Those who received a saline injection showed no interest in the “painkiller” chamber.

In addition, as Crook found out, cephalopod mollusks are capable of distinguishing different types of pain in different places of their own body. The specialist recorded a prolonged peripheral response on the way to the clam’s brain, in all likelihood reflecting the intensity of pain from acetic acid injections.

Heat wave caused 7,000 humpback whales to starve to death

by Mia Harris

written by Mia Harris

In 1972, a humpback whale nicknamed Festus was first spotted off the coast of southeastern Alaska. It is noted that it returned there every summer for 44 years, feeding in the cold, nutrient-rich waters of the North Pacific before returning to Hawaii to mate in the winter. In June 2016, the whale was found dead near Glacier Bay National Park. The cause of its death was cited as starvation due to the strongest sea heat wave in recorded history.

A new study presented at the Royal Society Open Science says the region’s humpback whale population declined by 20 per cent between 2013 and 2021 as warmer waters fundamentally changed the ecosystem. According to experts from Australia’s Sutherne Cross University, the heat wave from 2014-2016 significantly reduced ocean productivity, critically undermining the humpback whale population.

Data from the scientists show that the whale population peaked at 33,500 whales in the North Pacific in 2012, with an average increase of 6 per cent between 2002 and 2013. The maximum sea temperature recorded from 2014 to 2016 was 3-6 °C above average, nutrients in the region decreased, which cascaded throughout the ecosystem and affected all its inhabitants.
