Disproving string theory; interstellar comet arrives; lemurs age gracefully

Well, it is on July 12, which means (a) the steam summer sale is over and (b) it is really hot outside in the northeast of the United States this week, the researchers discovered a new fresh fish and named it after Dark Vader. An analysis of the DART mission suggests that, even if it has proven that an impactor could change the trajectory of an asteroid, it has ejected rocks in unpredictable directions which could complicate other impact missions. And archaeologists have discovered a rocky art panel that could represent an elite individual from the first dynasty.

In addition, physicists want to try to refute the theory of strings to LHC; Atlas identified the third known interstellar object entering the solar system, a comet which can have 7 billion years; And a study of lemurs highlights human “inflammage”, a chronic inflammation which causes the appearance of pathologies linked to aging:

Creation of energy matter to refract it the theory of strings

The theory of strings is useful because it reconciles the standard model of particle physics and general relativity with its underlying hypothesis: that all particles, including the theoretical particles representing gravity, are tiny vibrating strings through several dimensions. But it is a framework that can probably never be tested because when you ask a physicist how to prove it, he offers thought experiences in the voice of Neil Degrasse Tyson as “imagine that you had an accelerator of particles the size of the galaxy of the Milky Way.” I therefore suppose that the theory of strings can one day be validated by the power of imagination.

But could there be a way to refute ropes theory? The researchers of the great collision of Hadrons try to determine where the theory of the strings fail: if the results of the collisides reveal something specifically prohibited by the theory of the strings, the whole theory is fundamentally defective or incomplete. They focus on a particle subgroup called 5 plits, and specifically, the clogged majorana, a theorized particle which is also its own antiparticle.

The 5 fold family is completely absent from the theory of strings, which cannot welcome them. However, the difficulty of identifying a Fermion Majorana lies in the enormous energy required to produce them. The chances of creating a drop considerably as energy increases. And even if the collision producing one, detecting it would be difficult because such massive particles decompose and disappear quickly.

But the identification would be used for two ends: first, it would confirm the theory of strings as a model of the universe. And secondly, he would answer long -standing questions about the nature of dark matter.

The third interstellar tourist arrives

On July 1, the Atlas telescope in Chile identified the third interstellar object known to enter the solar system, a comet rich in water called 3i / Atlas. Researchers say it could be more than 7 billion years old, much older than the solar system. Its trajectory suggests that it is native to the thick disc of the Milky Way, a region of old stars above and below the thin disc in which the solar system resides. Compets produced around a thick disk star would be likely to contain water.

The initial observations suggest that the 3i / Atlas is greater than the 1i / ‘Oumuamua, spotted in 2017 and 2i / Borosov, spotted in 2019. As the sun approaches, it will start to get out of steam, and it can already be active. The Vera C. Rubin observatory, which is now starting investigation operations, should discover between five and 50 interstellar visitors in the future, according to the predictions of the frequency of these objects.

Aging lemurs feel good, better than ever, why do you ask?

Over the past decade, researchers have made correlations between inflammation and the aging process, developing evidence of a process they have called “inflammat”. Essentially, the idea is that chronic low -grade inflammation develops with advanced age and could contribute to age -related pathologies, including the development of heart disease, stroke, diabetes and cancer accidents. Researchers have studied chronic low -grade inflammation and its effects on brain health, aging, health and even psychological problems such as depression.

In a new study involving lemurs with tail and Sifaka lemurs, researchers from the Duke University have discovered that the species shows no change related to age in the markers of oxidative stress. “Unlike our predictions, none of the species has shown age -related change in one or the other marker of oxidative stress. None of the species of lemurs have shown age -related change in inflammation; if anything, unlike our prediction, lemurs with ancrual tail have shown a marginal drop in inflammation with age”, explains the Biologist Elaine Guevara. The discovery suggests that lemurs avoid “inflammant” as felt by humans and demonstrate that this is not a universal characteristic of primates.
