Harmful protein waste in the muscle
- ScienceDaily
- 21/6/14 21:40
An international research team identified the cause of a rare muscle disease. According to these findings, a single spontaneously occurring mutation results in the muscle cells no longer being able to correctly break down defective proteins. The condition causes severe heart failure in children, accompanied by skeletal and respiratory muscle damage. The study also highlights experimental...
Does zinc inhibit or promote growth of kidney stones? Well, both

- 21/6/14 21:39
In the first study to validate conflicting theories, a researcher has confirmed that the zinc actually does inhibit and promote the growth of kidney stones at the same time.
Dark matter is slowing the spin of the Milky Way's galactic bar
- ScienceDaily
- 21/6/14 21:39
For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured. The researchers say it gives a new type of insight into the nature of dark matter, which acts like a counterweight slowing the spin.

Biodiversity 'hotspots' imperiled along California's streams
- ScienceDaily
- 21/6/14 21:39
A study of woodland ecosystems that provide habitat for rare, endangered species along streams, rivers throughout California reveals some ecologically important areas are inadvertently benefiting from water humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term...

For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact.
Making a meal of DNA in the seafloor
- ScienceDaily
- 21/6/14 21:39
While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source. One bacterium newly named by the team in fact is a true expert in degrading DNA.
Near-field routing of hyperbolic metamaterials

- 21/6/14 21:39
Researchers recently demonstrated an all-electric scheme able to flexibly control the propagation direction of near-field light.
Insulators turn up the heat on quantum bits
- ScienceDaily
- 21/6/14 21:39
Physicists have long suspected that dielectric materials may significantly disrupt ion-trap quantum computers. Now, researcher have developed a new method to quantify this source of error for the first time. For the future operation of quantum computers with very many quantum bits, such noise sources need to be eliminated already during the design process if possible.
Persistence pays off in the human gut microbiome
- ScienceDaily
- 21/6/14 21:39
The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health -- but how is it sustained?
An unusual symbiosis of a ciliate, green alga, and purple bacterium
- ScienceDaily
- 21/6/14 21:39
The intracellular purple sulfur bacterium 'Candidatus Thiodictyon intracellulare' has lost the ability to oxidize sulfur and now supplies a ciliate with energy from photosynthesis.
Climate conditions during the migration of Homo sapiens out of Africa reconstructed
- ScienceDaily
- 21/6/14 21:39
Climate reconstruction of the last 200,000 years from East Africa illustrates the living conditions of Homo sapiens when they migrated out of Africa / Homo sapiens was mobile across regions during wet phases and retreated to high altitudes during dry phases.
The evolution of good taste
- ScienceDaily
- 21/6/14 21:39
Does evolution explain why we can't resist a salty chip? Researchers found that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami and sweet.
New combination of materials provides progress toward quantum computing
- ScienceDaily
- 21/6/14 21:39
Engineers have demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices' properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward...
Researchers model impact of blood pressure control programs at barbershops nationwide
- ScienceDaily
- 21/6/14 21:38
Investigators built a model to examine the potential impact of implementing blood pressure control programs at barbershops nationwide and found that such programs could reach one in three Black men with uncontrolled blood pressure nationally.
Scientists expose the cold heart of landfalling hurricanes
- ScienceDaily
- 21/6/14 19:12
Fearsome and powerful, hurricanes can wreak massive destruction when they hit land. But while most hurricanes then weaken, others can strengthen again into extratropical cyclones and caused further damage inland. Now, researchers have used simulations to uncover the presence of a cold core inside decaying hurricanes - an unexpected discovery that could help forecasters predict the level of extreme...
