How Long Should a Scientific Publication be?

by Richard Kunert in Brain's Idea

In one word: short. In two words: it depends. A neuroscience expert faces the challenge of 100 new neuroscience articles being published on a daily basis. S/he will never be able to read all that. So, what can be done to get your own publication known to the community? . 1) Know the reader and [...]... Read more »

'Tis the season to be Doggy, fa la la la laaaa...

by Cobb & Hecht in Do You Believe In Dog?

Hey Julie, I absolutely LOVE Project: Play with your Dog study and how the Horowitz Dog Cognition Lab are crowd sourcing using citizen science! I don't think a better way of contributing to scientific understanding can possibly exist! I look forward to hearing updates about how the research goes. I will certainly participate - next time we head to the river to play, we'll take our camera to get some video! So you might have noticed the silly season of festivity has landed upon us... Assumi........ Read more »

Are You Healthy Enough to Be a Space Tourist?

by Elizabeth Preston in Inkfish




Space travel for regular folks is almost here. But before jumping on board the nearest spacecraft, amateur astronauts and their doctors might want to consider the health risks. Although standard air travel is more boring than spaceflight, it's also less likely to shrink your bones or deform your eyeballs.

"Practically only the healthiest people have flown in space so far," says Marlene Grenon, a vascular surgeon at UCSF who researches the effects of microgravity on the body. Government astro........ Read more »

Nasa is developping graphene based sensors

by Jean-Christophe Lavocat in Graphenea ~ News about Graphene

The famous US aerospace and aeronautics agency NASA is currently developing sensors based on graphene. The main leader of the initiative, Mahmooda Sultana, joined NASA's Goddard Space Flight Center in Greenbelt two years ago. She had since then won research and development fundings to install graphene production facilities.... Read more »

Seven Galaxies have been found that came into being a little after the birth of Universe

by Usman Paracha in SayPeople

NASA's Earth orbiting Hubble Space Telescope has helped the scientists to observe the galaxies that are more than 13 billion years old.

This research has been accepted for publication in The Astrophysical Journal Letters.

With the help of NASA's Hubble Space Telescope, scientists have found seven previously unknown galaxies that were formed a little after the birth of the universe. These are found in the redshift range of 8.6 to 11.9. Redshift refers to the change in the spectrum........ Read more »

Earliest stars were formed when the age of the Universe was…

by Usman Paracha in SayPeople

Recently, scientists from MIT published a research paper in the journal Nature in which they showed their work of “Extremely metal-poor gas at a redshift of 7”. They utilized infrared spectrometer, which they placed onto the Magellan Telescope, a massive ground-based telescope in Chile. They calculated the elements and based on the observations about the heavy elements they believe that the earliest stars might have been formed 750 million years after the formation of Universe.

New type of chemical bonding in the shining universe

by Usman Paracha in SayPeople

Scientists found new type of chemical reaction at molecular level that is thought to change the views about chemical compound formation.

This research has been published online in the July 20th issue of the journal Science.

“We discovered a new type of chemical bonding,” University of North Dakota’s computational chemist Mark Hoffmann, who is known for his work on theory and computational modeling of chemical compound synthesis, said in a statement. “That’s a ........ Read more »

Star formation started after 750 million years of the formation of Universe; Research

by Usman Paracha in SayPeople

Scientists have found that very first stars came into being after about 750 million years of the Universe’s life.

This research has been published online in the journal Nature.

In this study, researchers analyzed most distant known quasar with the help of infrared spectrometer, which they placed onto the Magellan Telescope, a massive ground-based telescope in Chile. This quasar is about 13 billion light-years from Earth and helped to study the universe in its infancy. Researchers fou........ Read more »

Life Beneath the Ice

by GDW in The Beast, the Bard and the Bot

Somewhere on the cold continent of Antarctica, we find Lake Vida, a frozen lake covered with a massive ice sheet at least 21 meters thick. Beneath the ice lies supersalty brine (about seven times as salty as average sea water. And this brine is not only very salty, it’s also quite cold at -13°C. Underneath [...]... Read more »

Cosmic refinery

by Perikis Livas in Chilon

What sounds like science fiction is actually reality: using the 30m-telescope of the Institute for Radio Astronomy for astronomical observations in the millimetre range of wavelengths, astronomers have detected, for the first time, the interstellar molecule C3H , in our galaxy. It belongs to the hydrocarbon family and is thus part of major energy resources of our planet, i.e. petroleum and natural gas. The discovery of this molecule at the heart of the famous Horsehead Nebula in the Constellatio........ Read more »

Astronomers have for the first time found a rogue planet that appears to be wandering through space on its own, unattached to any star. The free-floating body, known as CFBDSIR2149, was discovered by astronomers using ESO’s Very Large Telescope and the Canada-France-Hawaii Telescope. Read more on TGDaily.com. Source: P. Delorme, J.

Every Black Hole Contains a New Universe

by Perikis Livas in Chilon

Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It’s a theory that has been explored over the past few decades by a small group of physicists including myself.
Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible “singularity,” an infinitely small point co........ Read more »

Mysteries of the Neutrino: Physicists Investigate the Big Bang Particle

by Perikis Livas in Chilon

Scientists at the University of Huddersfield are collaborating with experts at some of the world’s leading research institutes in an attempt to unravel the mysteries of a particle that played a role in the creation of the universe.

The existence of neutrinos and anti-neutrinos — particles that are almost massless and which travel nearly at light speed from one side of Earth to the other — was confirmed more than 50 years ago. Scientists believe that they were created at the ........ Read more »

A burst of activity in the middle of the Milky Way

by Perikis Livas in Chilon

As black holes go, Sagittarius A** is relatively low-key. The black hole at the center of our galaxy emits very little energy for its size, giving off roughly as much energy as the sun, even though it is 4 million times as massive.

However, astronomers have observed that nearly once a day, the black hole rouses to action, emitting a brief burst of light before settling back down. It’s unclear what causes such flare-ups, and scientists have sought to characterize these periodic bursts in........ Read more »

Earth’s magnetic shield behaves like a sieve

The findings have implications for modelling the dangers posed by space weather and could also help us better understand the magnetic environments around Jupiter and Saturn.... Read more »

Why You Should Reject the “Rejection Improves Impact” Meme

by caseybergman in I wish you'd made me angry earlier

Over the last two weeks, a meme has been making the rounds in the scientific twittersphere that goes something like “Rejection of a scientific manuscript improves its eventual impact”.  This idea is based a recent analysis of patterns of manuscript submission reported in Science by Calcagno et al., which has been actively touted in the [...]...

Searching for Extraterrestrial Microbes

by Jason Carr in Wired Cosmos

Locating thermophiles in other parts of the universe could very well aid in the search for extraterrestrial life. Most people have agreed that if life is found among the stars, it will be microbial (at least in the near-term future). Many individuals have also suggested that intelligent life forms might very well be extinct in [...]... Read more »
