How plump organic tomatoes were created using ancient genetic engineering

If you like big, juicy tomatoes you can thank a mutation in the Cell Size Regulator (CSR) gene that occurred during the tomato domestication process thousands of years ago.

it's no secret that ancient people genetically engineered vegetables to be larger and have more calories - food was scarce. When humans first began cultivating the wild tomato in the Andean mountain regions of Ecuador and Northern Peru, they continually engaging in such artificial selection. That is why today tomatoes can weigh 1,000 times more than the natural kind.

Will banning highly hazardous pesticides reduce suicides in Asia?

Will banning every method people use to commit suicide prevent suicide? Some people think so. In the United States, over 50 percent of gun deaths are suicide so people want those banned. In Japan, rope would have to be banned. In Sri Lanka, it's pesticides.

Low dose radiation could harm cardiovascular health

The controversial linear no-threshold model (LNT) model has long been used by the US Nuclear Regulatory Commission as a conservative model for estimating radiation risk, but it is not without critics. People who visit a beach in Brazil, with extremely high levels of radiation, instead believe it has recuperative powers, and studies have shown similar effects.

A practical test for the carrier of “good” cholesterol, HDL

A practical test for the carrier of “good” cholesterol, HDL

High-density lipoprotein cholesterol (HDL-C) is considered "good" because because HDL particles removes excess cholesterol from arterial walls and transport them back to the liver.

But how well does an individual's HDL accept cholesterol? A new test says it can more easily show.

Hackfest wants to figure out how to predict mosquito-borne disease epidemics

Computer programmers want to develop early warnings and response systems for mosquito-borne epidemics, and they hope to make progress in a three-day meetup to develop a decision-making dashboard solution that helps health organizations to proactively meet the threat of future outbreaks of Zika, Dengue and Chikungunya.

Lab-grown cartilage grown shows similar mechanical and chemical properties to natural cartilage, which allows our joints to move smoothly, according to a new study. 

Previously unpublished Alemtuzuma trial data shows effects of Multiple Sclerosis drug

The phase III trial datasets of Alemtuzumab have been published and show the drastic response of the immune system in patients with Multiple Sclerosis.

How spider silk can help premature babies

How spider silk can help premature babies

A special lung wash (surfactant) used in the care of premature babies could be getting a boost from spider silk. Surfactants help preterm babies by reducing the surface tension in the ends of the respiratory tree (pulmonary alveoli) and allowing them to be inflated at the moment of birth. Curosurf, the most globally widespread drug, is produced by the isolation of proteins from pig lungs, a process that is expensive, complicated and potentially risky.

New test can more quickly diagnose sepsis

 Sepsis is a potentially life-threatening complication of bacterial infections.

Rapid diagnosis of sepsis in hospitalized patients is crucial because in severe cases because there is an average 7.6 percent decrease in survival rate per hour from the onset of low blood pressure without effective antimicrobial treatment.

Early identification of a pathogen increases the chance of targeting the correct agent and may avoid misuse of antibiotics.
