The discovery of where blood comes from could give insights on blood-related diseases.

Scientists discover origin of blood cells

Billions of highly specialized cells run through our veins. They make up our blood, a fascinating fluid that plays the significant roles of transport as part of the cardiovascular and respiratory systems and of pathogen detection and elimination in the immune and lymphatic systems.

The severity of a patient’s cold and how often they are sick is linked to social isolation and loneliness.

Self-reported loneliness contributes to sickness

Researchers at Rice University recently studied the effects of loneliness on the symptoms of the common cold. They found that patients who identified as lonely reported more acute cold symptoms while more sociable patients tended to report feeling less under the weather.

Exposure to airborne lead oxide can lead to lower IQ in children.

Lead exposure may contribute to lower IQ

Lead is a common element found in many different everyday objects. Despite the widespread knowledge of its toxicity to the human body, or any biological system, lead continues to be mined and used in items ranging from handheld electronic devices to batteries in cars to x-ray protective shields at the dentist’s office.

The population of the brown howler monkey has diminished in Brazil.

Yellow fever plagues Brazilian monkeys

In accordance with current trends of animal endangerment, the brown howler monkey community has lost thousands of members. The brown howler is a New World monkey native to southeastern Brazil that has recently experienced declines in population due to mortality from yellow fever exposure.



NASA evaluates space farming development

U.S. President Donald Trump recently signed a $19.5-billion bill to fund the programs of the National Aeronautics and Space Administration (NASA), including NASA’s long-term goal to send humans to Mars by the 2030s.

Fruit-consuming species must use more brain power to find food.

Species diet shown to affect brain size

A new study has found that certain species may be more intelligent because of their diet. The discovery has thrown into question the scientific consensus that a species’ sociality determines its intelligence.

DNA could be used to store data.

Scientists store binary data in DNA strands

How can the complex compilation of Peter Jackson’s Lord of the Rings trilogy be broken down into unintelligible bits of binary data, stored on complex electronic computer systems and then finally transmitted with the tap of a finger?

Drinking alcohol is associated with decreased risk of heart disease, but exercise is a better alternative.

Moderate alcohol intake lowers heart disease risk

Over the past few decades, several systematic studies and meta-analyses have been conducted to evaluate the relationship between alcohol consumption and cardiovascular diseases. Most of the studies suggest that moderate drinking is associated with a lower risk of developing heart diseases compared to non-drinkers and heavy drinkers.
