Coasta de Est din Statele Unite ale Americii, "aprinsă" de un meteor

Cerul de deasupra Coastei de Est din Statele Unite ale Americii s-a luminat noaptea trecută, după ce un meteor a trecut peste New York, iar reţelele sociale s-au umplut de imagini cu acesta, majoritatea însă false.

Cei care locuiau în zonă s-au dus rapid pe Twitter şi Facebook pentru a anunţa lumina foarte rapidă care a trecut peste ei, iar mulţi au pus fotografii, dar acestea nu erau reale. NASA a confirmat totuşi evenimentul prin vocea lui Bill Cooke, de la centrul de evenimentele meteoroidale. El a spus că ar fi vorba de "un singur meteor". 

Nasa Confirms Meteor After 'Fireball' Reports

A flash of light that streaked across the sky over the east coast of the United States was probably a single meteor, Nasa has announced.

"Judging from the brightness, we're dealing with something as bright as the full moon," said Bill Cooke, who works for Nasa's Meteoroid Environmental Office.

"We basically had a boulder enter the atmosphere over the northeast."

НАСА: над восточным побережьем США пронесся метеор (видео)

Представитель американского аэрокосмического агентства НАСА Билл Кук заявил, что пролетевший накануне над восточным побережьем США болид был "единичным метеором".

"Судя по его яркости, мы имеем дело с чем-то столь же ярким, как полная Луна", - сказал он Ассошиэйтед пресс. Как добавил представитель НАСА со ссылкой на сообщения очевидцев, небесное тело напоминало огненный шар, который двигался по направлению к юго-востоку страны.

Умные больше плачут: слезы развивают мозг

Плакать наши предки стали раньше, чем говорить - только так можно было сообщить соплеменникам о своих чувствах и мыслях

Среди всех жителей Земли человек - единственное существо, которое может рыдать от счастья или горя. Не удивительно ли, что довольно простая способность разводить мокроту столь уникальна? Почему она присуща только гомо сапиенс? Ответ на этот вопрос дает новая книга профессора неврологии из Университетского Колледжа Лондона Майкла Тримбла «Отчего людям нравится плакать».

Ogdoad of Hermopolis

Definition: The Ogdoad of Hermopolis was the group of gods who created the world, or at least the sun, according to Egyptian mythology centered in Hermopolis Magna. The Ennead of Heliopolis is a contrasting grouping of 9 creating Heliopolitan gods. A third cosmogony is the Memphis Theology, which is centered on the god Ptah.

Since the Ogdoad of Hermopolis is an Ogdoad, there are 8 deities, in 4 pairs of males and females. Their functions may be described as chaos and generation, eternity, darkness, and moisture, or as invisibility, endlessness, obscurity, and water, all perhaps in a primeval watery chaos. The pairs are spelled out in English as Amun and Amaunet, Heh (Huh) and Hehet, Kek and Keket, and Nun and Naunet, although spelling varies. Sometimes in later representations, the male (the first in each pair) is depicted as frog-headed and the female with a snake head, all generated spontaneously from the Nile mud.

Sideline quasars helped to stifle early galaxy formation

University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say "sideline quasars" likely teamed up with it to heat abundant helium gas billions of years ago, preventing small galaxy formation.

CU-Boulder Professor Michael Shull and Research Associate David Syphers used the Hubble Space Telescope to look at the quasar -- the brilliant core of an active galaxy that acted as a "lighthouse" for the observations -- to better understand the conditions of the early universe. The scientists studied gaseous material between the telescope and the quasar with a $70 million ultraviolet spectrograph on Hubble designed by a team from CU-Boulder's Center for Astrophysics and Space Astronomy.

Best Image of Big Bang Afterglow Ever Confirms Standard Cosmology

If the universe were ice cream, it would be vanilla. That's the take-home message from researchers working with the European Space Agency's orbiting Planck observatory, who today released the most precise measurements yet of the afterglow of the big bang—the so-called cosmic microwave background (CMB) radiation. The new data from Planck confirm cosmologists' standard model of how the universe sprang into existence and what it's made of. That may disappoint scientists who were hoping for new puzzles that would lead to a deeper understanding.

Brain Researchers Can Detect Who We Are Thinking About

Scientists scanning the human brain can now tell whom a person is thinking of, the first time researchers have been able to identify what people are imagining from imaging technologies.

Work to visualize thought is starting to pile up successes. Recently, scientists have used brain scans to decode imagery directly from the brain, such as what number people have just seen and what memory a person is recalling. They can now even reconstruct videos of what a person has watched based on their brain activity alone. Cornell University cognitive neuroscientist Nathan Spreng and his colleagues wanted to carry this research one step further by seeing if they could deduce the mental pictures of people that subjects conjure up in their heads.

New details of atomic structure of water under extreme conditions found

Scientist from Dortmund, Helsinki, Potsdam, and the ESRF have revealed details of the microscopic atomic structure of water under extreme conditions. The results have now been published in the Proceedings of the National Academy of Sciences of the USA.

Liquid water remains a mystery even after decades of dedicated scientific investigations and researchers still struggle to fully describe its unusual structure and dynamics.

Saga of ‘the Hobbit’ highlights a science in crisis

To state the obvious: human evolution is not without its drama – and the latest salvo in the ongoing Hobbit, or Homo floresiensis, battle confirms this yet again.

The 2004 announcement of Homo floresiensis – dubbed “the Hobbit” – marked the beginning of a saga all too frequent in the rarefied field of human evolution.

Immediately upon its announcement, anthropologists divided along long-entrenched party lines to support or oppose the find as something novel to science.
