Open Skies: An Update

Posted: 29 Jul 2015 09:32 AM PDT

In April 2015, I wrote about the fight brewing in the U.S. between the three major international air carriers (American, Delta and United) and the three Gulf carriers (Qatar, Emirates and Etihad). My thesis was that this was part of a strategy to get better treatment from the U.S. government in a variety of areas, […]

Scientists discover link between common medications and serious falls in older men

Posted: 28 Jul 2015 04:49 PM PDT

A significant link between serious falls causing injury in older men and a particular group of commonly used medicines has been identified by a group of researchers. Many medicines which are commonly prescribed for older people for bladder problems, depression, psychosis, insomnia, and respiratory problems, have anti-cholinergic effects. The medications affect the brain by blocking a key chemical called acetylcholine which is involved in passing messages between nerve cells. This can lead to side effects including blurred vision, increased heart rate, sedation and confusion.

Controlling phase changes in solids

Posted: 28 Jul 2015 01:52 PM PDT

Rewritable CDs, DVDs and Blu-Ray discs owe their existence to phase-change materials, those materials that change their internal order when heated and whose structures can be switched back and forth between their crystalline and amorphous phases. Phase-change materials have even more exciting applications on the horizon, but our limited ability to precisely control their phase changes is a hurdle to the development of new technology.

New chemistry makes strong bonds weak

Posted: 28 Jul 2015 01:52 PM PDT

Researchers have developed a new chemical reaction that breaks the strongest bond in a molecule instead of the weakest, completely reversing the norm for reactions in which bonds are evenly split to form reactive intermediates. The non-conventional reaction is a proof of concept that will allow chemists to access compounds that are normally off-limits to this pathway.

When being an immigrant makes it more–not less–likely to have a job

Posted: 28 Jul 2015 01:26 PM PDT

Race and education shape employment outcomes for U.S.- and foreign-born blacks in surprising ways. This is the first time researchers have examined how the interactions between race and nativity status affect employment outcomes. Up until now, research on nativity status and employment outcomes had been race-blind -- and those prior findings could not have been more different.

Sleepy fruitflies get mellow

Posted: 28 Jul 2015 01:24 PM PDT

Whether you're a human, a mouse, or even a fruitfly, losing sleep is a bad thing, leading to physiological effects and behavioral changes. Researchers used fruitflies to probe deeper into the cellular and molecular mechanisms that govern aggression and sleep and found that sleep deprivation reduces aggression in fruitflies and affects their reproductive fitness. They identified a related molecular pathway that might govern recovery of normal aggressive behaviors.

Past and present sea levels in the Chesapeake Bay Region, USA

Posted: 28 Jul 2015 01:24 PM PDT

Scientists write that sea-level rise (3.4 mm/yr) is faster in the Chesapeake Bay region than any other location on the Atlantic coast of North America, and twice the global average (1.7 mm/yr). They have found that dated interglacial deposits suggest that relative sea levels in the Chesapeake Bay region deviate from global trends over a range of timescales.

Chill-tolerant hybrid sugarcane also grows at lower temperatures, team finds

Posted: 28 Jul 2015 09:36 AM PDT

US farmers have long hoped to extend sugarcane's growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these 'miscanes,' as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.

Pygmies show growth plasticity is key to human evolution

Posted: 28 Jul 2015 09:03 AM PDT

While the stature of pygmies is well-suited to tropical rainforests, the mechanisms underlying their growth remain poorly understood. In order to decipher these mechanisms, a team of scientists studied a group of Baka pygmies in Cameroon. Their findings revealed that their growth rate differed completely from that of another pygmy cluster, despite a similar adult height, which implies that small stature appeared independently in the two clusters.

Illuminating mechanisms of repetitive thinking

Posted: 28 Jul 2015 09:03 AM PDT

The ability to engage in mental time travel is a unique and central part of the human experience. And yet this very ability can have detrimental consequences for both physical and mental well-being when it becomes repetitive and uncontrolled. New research investigates this kind of repetitive thinking, exploring the core psychological processes that underlie maladaptive thought processes like worry and rumination.

National study of deep brain stimulation for depression fails to demonstrate efficacy

Posted: 28 Jul 2015 09:03 AM PDT

Depression is a leading cause of disability worldwide, and treatment-resistant symptoms of depression have a terrible personal and societal cost. They can devastate lives, careers, and families. Some severely ill patients may be unable to attend to even the basic elements of self-care, while others attempt or complete suicide. Now researchers report the results of the first large-scale, randomized, sham-controlled trial of deep brain stimulation treatment for treatment-resistant symptoms of depression.

Diabetics who skip breakfast provoke hazardous blood sugar spikes

Posted: 28 Jul 2015 09:01 AM PDT

A new study reveals how skipping breakfast affects people with type-2 diabetes.

Experimental MERS vaccine shows promise in animal studies

Posted: 28 Jul 2015 09:01 AM PDT

A two-step regimen of experimental vaccines against MERS prompted immune responses in mice and rhesus macaques. Vaccinated mice produced broadly neutralizing antibodies against multiple strains of the MERS coronavirus, while vaccinated macaques were protected from severe lung damage when later exposed to MERS-CoV. The findings suggest that the current approach, in which vaccine design is guided by an understanding of structure of viral components and their interactions with host cells, holds promise for developing a similar human MERS vaccine regimen.

Origins of life: New model may explain emergence of self-replication on early Earth

Posted: 28 Jul 2015 08:07 AM PDT

One question of the origin of life in particular remains problematic: what enabled the leap from a primordial soup of individual monomers to self-replicating polymer chains? A new model proposes a potential mechanism by which self-replication could have emerged. It posits that template-assisted ligation, the joining of two polymers by using a third, longer one as a template, could have enabled polymers to become self-replicating.

Link between mood, pain in rheumatoid arthritis patients

Posted: 28 Jul 2015 08:05 AM PDT

Depressive symptoms and mood in the moment may predict momentary pain among rheumatoid arthritis patients, according to researchers. Individuals in the study who reported greater depressive symptoms in general also reported more common pain and restrictions in daily life. This effect of depressive symptoms was not due to differences in day-to-day mood.

'Carbon sink' detected underneath world's deserts

Posted: 28 Jul 2015 08:05 AM PDT
