October is coming to an end and the last long weekend of the year is coming. And to the delight of the little ones, Halloween arrived, of course. They and they are the ones who enjoy these celebrations the most.
In this edition: the terrifying image of an ant that went viral, the strange object light blue that has astonished astronomers and how the global warming threatens cold-blooded animals.
1- ANTONIA GIRARDI, DIRECTOR OF FIDOCS: “THERE ARE FILMS THAT ARE NEW WAYS OF THINKING AND UNDERSTANDING CINEMA”
The journalist Emilia Aparicio interviewed the director of the Santiago International Documentary Festival (FIDOCS)which will begin with nothing less than a documentary about the recent Nobel Prize for Literature, Annie Ernaux.
This year the three thematic focuses will be related to colonialism, environmental violence and a series of works by the German visual artist and essayist Hito Steyerl.
In this interview,the director of the festival takes a tour of the national program and a reflection on the relationship between visual art and documentaries.
The full interview is here.
two- THE VIRAL PHOTO OF AN ANT
No, it’s not an alien. Nor a Hollywood production. It is the portrait of a… carpenter ant.
It was one of the selected photographs in the Nikon Small World contestand it soon went viral.
Contrary to what might be believed, it is not his eyes – nor his teeth – that can be seen in the photomade by the Lithuanian Eugenijus Kavaliauskas.
The photographer achieved an honorable mention with the image,simply titled “Ant” (“Hormiga” in English).
“I always look for details, shadows and unseen corners. The main objective of photography is to discover. the photographer assured Insider.
3- NASA CREATED SCIENTIFIC TEAM TO STUDY UFOs
I have always been fascinated by UFOs and my guilty pleasure is the “Ancient Aliens” series.
However, by instruction of the United States Government,now things got serious, because there are scientists involved. Several of them probably never imagined it, but the truth is that they have been selected by NASA to investigate nothing less than the phenomenon of unidentified flying objects (UFOs).
The announcement of the formation of the teamit had been made several months ago, but now its members were known.
The NASA official responsible for orchestrating the study is Daniel Evans.deputy associate administrator for research in NASA’s Science Mission Directorate, and the study team will be chaired by David Spergel, president of the Simons Foundation, known for funding research in basic math and science.
They include Nadia Drake, a freelance science journalist and contributing writer for National Geographic;David Grinspoon, senior scientist at the Planetary Science Institute in Tucson; former astronaut Scott Kelly; Matt Mountain, president of the Association of Universities for Research and Astronomy (AURA); and biological oceanographer Paula Bontempi.
4- GLOBAL HEAT THREATENS COLD-BLOODED ANIMALS
Despite being minimized, global warming is already a sad reality that threatens to be deadly. This is revealed by a recent investigation.
Every degree of extra global heat increases heat stress in cold-blooded animals.and brings them closer to death, even in a scenario of moderate temperature rise, according to a study published by the journal Journal of Experimental Biology.
Research recalls that ectothermic (cold-blooded) animals,like fish, amphibians and reptiles, they are very vulnerable to global warming, since they depend on external sources to regulate their temperature and biochemical processes.
Therefore, ectothermic animals usually live in habitats with moderate temperaturesand although they are able to withstand – to a certain extent – stressful temperature levels, their tolerance is limited by the intensity and duration of thermal stress.
The calculations are terrifying: Future increases in maximum temperatures around the world could spike heat death rates by 774% for terrestrial cold-blooded animals and 180% for aquatic ones by the year 2100.
It would be another proof of how we underestimate global warming.
5- “EXOTIC” STELLAR OBJECT DEFYS LAWS OF PHYSICS
As a child I grew up with the series “Cosmos”, by Carl Sagan, that made me fascinate with space and its phenomena. Therefore, one of my childhood dreams was to become an astronomer. And although I was not, these issues continue to interest me.
In this case, the recent measurement of the mass of a neutron star reveals unusual characteristics for this type of object.which question its categorization and open new questions for the astronomical community.
Specifically, the interstellar object HESS J1731-347 exhibits features as “exotic”that defy the laws of physics, so it might not be a neutron star as previously thought, according to a recent article published by the magazine Nature.
The authors state in their research that this neutron star could actually be a more “exotic” object: a quark star. Recall that quarks are fundamental subatomic particles that combine to form compound particles such as protons and neutrons.
For now, more research will be required to determine exactly what kind of object it is and then to reach a consensus. If the hypotheses are validated, HESS J1731-347 would be the first confirmed strange star and the theory behind its existence would also be confirmed.
And now, we say goodbye until next time. And if you are going to go out for a few days, take advantage of resting and drive carefully. It is already known that it is better to lose a minute in life, than life in a minute.
