The difference between life and death in the operating room, on the battlefield or during a police shootout often comes down to the ability to adapt to the unexpected. Sleep deprivation may make it difficult to do so, according to a study that for the first time created a laboratory experiment that simulates how sleep loss affects critical aspects of decision making in high-stakes, real-world situations

In a study of nearly 26,000 beneficiaries of Tricare, the military health system, those taking statin drugs to control their cholesterol were 87 percent more likely to develop diabetes. The research confirms past findings on the link between the widely prescribed drugs and diabetes risk. But it is among the first to show the connection in a relatively healthy group of people. The study included only people who at baseline were free of heart disease, diabetes, and other severe chronic disease.

A promising new therapeutic approach for hereditary blindness based on a technology termed 'optogenetics' is to introduce light-sensing proteins into these surviving retinal cells, turning them into 'replacement photoreceptors' and thereby restoring vision. However, several factors limit the feasibility of a clinical optogenetic therapy using traditional light-sensitive proteins, as they require unnaturally high and potentially harmful light intensities and employ a foreign signaling mechanism within the target retinal cells.

Scientists have come a step closer to understanding why people exposed to household air pollution (HAP) are at higher risk of lung infections such as pneumonia and tuberculosis. Three billion people worldwide are exposed to HAP from the fuels they burn to cook, light and heat with at home. Frequently, charcoal, wood and food waste are burned and generate high concentrations of smoke particles. This exposure is associated with increased risk of pneumonia, particularly in low and middle income countries where bacterial pneumonia is the biggest cause of infant mortality. This risk is well known, but the reasons are not.

The ability that some people have to use echoes to determine the position of an otherwise silent object, in a similar way to bats and dolphins, requires good high-pitch hearing in both ears, according to new research. This builds on recent research that demonstrated conclusively that some sighted and blind people could use echoes in this way. What wasn't clear until now was how important high-frequency hearing in both ears is.

’Super-cool' way to deliver drugs Some substances, when they undergo a process called 'rapid-freezing' or 'supercooling,' remain in liquid form -- even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
Negative regulator of natural killer cell maturation discovered A new study has identified a regulatory pathway in natural killer cells that inhibits their maturation and homing behavior. Natural killer cells are one of the body's first lines of defense against viruses and cancer. The findings could lead to new strategies for boosting natural-killer cell activity against cancer and viral infections, scientists say.

FDA inspectors report long list of problems at Blue Bell plants Inspection teams from the U.S. Food and Drug Administration reported numerous problems after recent visits to three production facilities owned and operated by Blue Bell Creameries The company announced that it was recalling all products (ice cream, frozen yogurt, sherbet and frozen desserts) manufactured at all of its plants after receiving positive Listeria...
’Super-cool' way to deliver drugs Some substances, when they undergo a process called 'rapid-freezing' or 'supercooling,' remain in liquid form -- even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
Negative regulator of natural killer cell maturation discovered A new study has identified a regulatory pathway in natural killer cells that inhibits their maturation and homing behavior. Natural killer cells are one of the body's first lines of defense against viruses and cancer. The findings could lead to new strategies for boosting natural-killer cell activity against cancer and viral infections, scientists say.

In a study of nearly 26,000 beneficiaries of Tricare, the military health system, those taking statin drugs to control their cholesterol were 87 percent more likely to develop diabetes. The research confirms past findings on the link between the widely prescribed drugs and diabetes risk. But it is among the first to show the connection in a relatively healthy group of people. The study included only people who at baseline were free of heart disease, diabetes, and other severe chronic disease.

A promising new therapeutic approach for hereditary blindness based on a technology termed 'optogenetics' is to introduce light-sensing proteins into these surviving retinal cells, turning them into 'replacement photoreceptors' and thereby restoring vision. However, several factors limit the feasibility of a clinical optogenetic therapy using traditional light-sensitive proteins, as they require unnaturally high and potentially harmful light intensities and employ a foreign signaling mechanism within the target retinal cells.

Scientists have come a step closer to understanding why people exposed to household air pollution (HAP) are at higher risk of lung infections such as pneumonia and tuberculosis. Three billion people worldwide are exposed to HAP from the fuels they burn to cook, light and heat with at home. Frequently, charcoal, wood and food waste are burned and generate high concentrations of smoke particles. This exposure is associated with increased risk of pneumonia, particularly in low and middle income countries where bacterial pneumonia is the biggest cause of infant mortality. This risk is well known, but the reasons are not.

The ability that some people have to use echoes to determine the position of an otherwise silent object, in a similar way to bats and dolphins, requires good high-pitch hearing in both ears, according to new research. This builds on recent research that demonstrated conclusively that some sighted and blind people could use echoes in this way. What wasn't clear until now was how important high-frequency hearing in both ears is.

Countless research and self-help books claim that having more sex will lead to increased happiness, based on the common finding that those having more sex are also happier. Scientists now report that simply having more sex did not make couples happier, in part because the increased frequency led to a decline in wanting for and enjoyment of sex.

Scientists have come a step closer to understanding why people exposed to household air pollution (HAP) are at higher risk of lung infections such as pneumonia and tuberculosis. Three billion people worldwide are exposed to HAP from the fuels they burn to cook, light and heat with at home. Frequently, charcoal, wood and food waste are burned and generate high concentrations of smoke particles. This exposure is associated with increased risk of pneumonia, particularly in low and middle income countries where bacterial pneumonia is the biggest cause of infant mortality. This risk is well known, but the reasons are not.

The ability that some people have to use echoes to determine the position of an otherwise silent object, in a similar way to bats and dolphins, requires good high-pitch hearing in both ears, according to new research. This builds on recent research that demonstrated conclusively that some sighted and blind people could use echoes in this way. What wasn't clear until now was how important high-frequency hearing in both ears is.

FDA inspectors report long list of problems at Blue Bell plants Inspection teams from the U.S. Food and Drug Administration reported numerous problems after recent visits to three production facilities owned and operated by Blue Bell Creameries The company announced that it was recalling all products (ice cream, frozen yogurt, sherbet and frozen desserts) manufactured at all of its plants after receiving positive Listeria...
’Super-cool' way to deliver drugs Some substances, when they undergo a process called 'rapid-freezing' or 'supercooling,' remain in liquid form -- even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
Negative regulator of natural killer cell maturation discovered A new study has identified a regulatory pathway in natural killer cells that inhibits their maturation and homing behavior. Natural killer cells are one of the body's first lines of defense against viruses and cancer. The findings could lead to new strategies for boosting natural-killer cell activity against cancer and viral infections, scientists say.
