Because you can't eat just one: Star will swallow two planets
2014-06-02
Two worlds orbiting a distant star are about to become a snack of cosmic proportions. Astronomers announced today that the planets Kepler-56b and Kepler-56c will be swallowed by their star in a short time by astronomical standards. Their ends will come in 130 million and 155 million years, respectively.
"As far as we know, this is the first time two known exoplanets in a single system have a predicted 'time of death,'" says lead author Gongjie Li of the Harvard-Smithsonian Center for Astrophysics (CfA).
She presented her research today in a press conference at a meeting ...

Does your stomach bacteria protect you from obesity?
2014-06-02
The germ Helicobacter pylori is the cause of most stomach ulcers, but new research in Alimentary Pharmacology & Therapeutics suggests that treating the bacteria is linked to weight gain.
It is estimated that 50% of the global population may be infected with H. pylori; however, only 20% of infected people experience symptoms. New evidence suggests that patients treated for the infection developed significant weight gain compared to subjects with untreated H. pylori colonization.
By reviewing data taken from forty-nine studies with data from ten European countries, Japan, ...
Britain's urban rivers cleanest in 20 years
2014-06-02
Scientists from Cardiff University have found that Britain's urban rivers are the cleanest they've been in over two decades.
The 21-year study of over 2300 rivers measured the presence of clean-river invertebrates - a yardstick for river health – which during the days of heavy industry and poor sewage treatment had declined considerably, but now appear to be making a comeback.
Although climate change has warmed British rivers by around 1-2 degrees over recent decades, the findings suggest that improved pollution control has managed to offset its damaging effects on ...
Cystic fibrosis and diabetes link explained
2014-06-02
Many people with cystic fibrosis develop diabetes. The reasons for this have been largely unknown, but now researchers at Lund University in Sweden and Karolinska institutet have identified a molecular mechanism that contributes to the raised diabetes risk.
"The increased risk of diabetes has previously been explained by the fact that cystic fibrosis causes damage to the pancreas, where the blood-sugar regulating hormone insulin is produced. We are the first research group to show that the mutated gene that causes cystic fibrosis also plays an important role in the release ...

Why inflammation leads to a leaky blood-brain barrier: MicroRNA-155
2014-06-02
Until now, scientists have not known exactly how inflammation weakens the Blood-Brain Barrier, allowing toxins and other molecules access to the brain. A new research report appearing in the June 2014 issue of The FASEB Journal solves this mystery by showing that a molecule, called "microRNA-155," is responsible for cleaving epithelial cells to create microscopic gaps that let material through. Not only does this discovery help explain the molecular underpinnings of diseases like multiple sclerosis, but it also opens an entirely new avenue for developing therapies that ...

Doing more with less; in cellulo structure determinations
2014-06-02
Anyone involved in macromolecular crystallography will know that for many years scientists have had to rely on a multi-stage process utilizing protein, usually expressed in engineered cells, which is then extracted and purified before crystallization in vitro and finally prepared for analysis.
As a counter to this time-consuming and substantial scientific effort, there are a number of examples of protein crystallization events occurring in vivo, with next to no human input. In a case presented in a recent paper an insect virus exploits the phenomenon as part of its life ...

Transforming hydrogen into liquid fuel using atmospheric CO2
2014-06-02
Hydrogen is often touted as the fuel of the future. But because this gas is highly explosive, it must be stored and transported under pressure in specialized and expensive containers. Hydrogen therefore has issues in terms of safety, logistics, and profitability that could significantly limit its wider use. However, a solution might lie in research by EPFL scientists, who have developed a simple system based on two chemical reactions. The first reaction transforms hydrogen into formic acid, a liquid that is easy to store and less flammable than gasoline, while the second ...

CPAP rapidly improves blood pressure and arterial tone in adults with sleep apnea
2014-06-02
DARIEN, IL – A new study suggests that continuous positive airway pressure (CPAP) therapy rapidly improves blood pressure and arterial tone in adults with obstructive sleep apnea (OSA).
Results show that there was a significant reduction in systolic and diastolic blood pressures among sleep apnea patients who were compliant with CPAP therapy for three months. Successful treatment of sleep apnea also was associated with decreased vascular tone and arterial stiffness. Following one week of treatment withdrawal, these improvements disappeared and reverted to baseline values.
