Research data sharing: enhances chances that studies will be reproduced.
Over the past few years, the scientific community has expressed concerns over the reliability of scientific research, particularly biomedical research. Making the primary results of research–the actual data–more easily accessible to other scientists is seen as an important step to solve this problem. After all, reproducibility of research is at the heart of science. However, old habits die hard. And the custom of making all data fully available so that others can re-analyse and re-assess them is not yet fully ingrained in scientists’ modus operandi. Training may be required to change such habits while giving credit for people producing the original data, may also encourage data sharing and enhance reproducibility.

Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day.
According to the World Health Organization, nitrogen dioxide (NO2)-based air pollution contributes to over 7 million deaths per year – children and the elderly are particularly at risk. Thanks to research being carried out at Australia's RMIT University, however, it may soon be possible to
Innovations in 3D printing are marching toward us, in droves, faster than most people can keep up with today. There are so many, in fact, that it’s easy to start becoming desensitized to the... View the entire article via our website.
3-D printers typically produce hard plastic objects, but researchers at Carnegie Mellon Univ. have found a way to produce hair-like strands, fibers and bristles using a common, low-cost printer. The technique for producing 3-D-printed hair is similar to - and inspired by - the way that gossamer plastic strands are extruded when a person uses a hot glue gun.
"Many of us have been bestowed the project of a pen pal in school. Teachers assign these projects in hopes of children being able to get a glimpse of another child’s life and culture, opening their mind to how other kids around the world live. Hannah Herbst, a 15-year old teenager in Florida, did not take this project lightly but used her pen pal’s story to inspire a pretty impressive invention for harnessing energy from ocean currents.
“I found out that she’s living in energy poverty, and she doesn’t have access to things that I take for granted every day,” Herbst explains the motivation from her 9- year old pen pal in Ethiopia. “Then I was boating with my family through the Boca Raton Inlet, and our boat was really jerked around by the current. I thought, why not use this power?”"
The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.
The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.
Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity.
"The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there," Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.
Ali and coauthor Saurya Das at the University of Lethbridge in Alberta, Canada, have shown in a paper published in Physics Letters B that the Big Bang singularity can be resolved by their new model in which the universe has no beginning and no end.

Do you have a broken heart? Doctors can 'science' your way out of that, at least when it comes to coronary heart disease. Researchers from Stanford University found a type of cell that can fix damaged arteries.
The Hollow Earth theory states that the Earth is a hollow planet with ancient entrances to the subterranean world scattered throughout it, including near both polar caps. This theory has been reported since ancient times and scientists such as Edmund Halley have defended it throughout history.
From 1818-1826, the American John C. Symmes passionately supported the theory as well. According to him, there was a subterranean world inside our planet illuminated by a tiny sun, and that included mountains, forests, and lakes. Symmes launched a national campaign aiming to raise the necessary funds to send an expedition to the Arctic to search for an entrance to the subterranean world.
Meanwhile, the first man to fly over the poles, Richard E. Byrd, in his report said he “inspected about 26,000 km (16,155.7 miles) around and beyond the Pole.” This simple sentence with the words "beyond the Pole" are the foundation on which many advocates of the hollow earth theory accuse the US government (who funded Byrd’s flight) of a cover-up, saying that Byrd went into the Inner Earth.
