Suicide Rates In Older US Adults Linked To The Economy

General - March 3, 2015 - 4:08pm

How will we know if the economy has really gotten better, rather than using bogus claims about employment or how well Wall Street executives are doing? When senior citizens stop killing themselves.

Suicide rates for adults between 40 and 64 years of age in the U.S. rose about 40% since 1999, with a sharp rise after in 2007 that continued during the economic downturn of 2008 and on, which led to disproportionate effects on house values, household finances, and retirement savings for that age group. In a study published in the American Journal of Preventive Medicine, researchers found that external economic factors were present in 37.5% of all completed suicides in 2010, rising from 32.9% in 2005.

Enzyme Modification Boosts Crop Yields

Science2.0 - March 3, 2015 - 3:14pm
Enzymes are the workhorses of our bodies, they make biochemical reactions happen faster than they otherwise would and sometimes essential reactions would not happen at all without them. 

The Rubisco enzyme, the most abundant protein on the planet, has one of the most significant responsibilities in life on Earth - the conversion of carbon dioxide to organic compounds, the building blocks of all plant and animal cells.

Insulin Resistance, Behavioral Disorders Linked

Science2.0 - March 3, 2015 - 2:45pm
People with diabetes are prone to anxiety and depression but others with chronic diseases that require similar levels of management suffer from anxiety and depression less.

Why that might be is unclear but Joslin Diabetes Center researchers have offered an explanation, gleaned by genetically modifying mice to make their brains resistant to insulin. They found that the animals exhibited behaviors that suggest anxiety and depression, and then pinpointed a mechanism that lowers levels of the key neurotransmitter dopamine in areas of the brain associated with those conditions.

Peanut Consumption Decreases Mortality

Science2.0 - March 3, 2015 - 2:45pm
Want to lower your risk of dying from a heart attack? Go a little nuts.

Peanuts are getting a modern rehabilitation.  Except for severe cases, it has been found that peanut allergies will go away if kids eat them early, and when they reach adulthood they will have less likelihood of dying from heart disease - and be an equalizer across low-income and racially diverse populations.

Genetic Mutations Associated With Leukemia Are Almost Inevitable With Age

Science2.0 - March 3, 2015 - 2:45pm
A new paper based on a study of 4,219 people without any evidence of blood cancer nonetheless found that up to 20 percent of people aged 50-60 and more than 70 percent of people over 90 have blood cells with the same gene changes as found in leukemia.  

That means it is almost inevitable that we will develop genetic mutations associated with leukemia as we age, according to the authors investigating the earliest stages of cancer development used an exquisitely sensitive sequencing method capable of detecting DNA mutations present in as few as 1.6 percent of blood cells, to analyze 15 locations in the genome, which are known to be altered in leukemia.

HECA School Bus Filtration System Reduces Pollutants 88 Percent

Science2.0 - March 3, 2015 - 2:45pm
An on-board air filtration system called  high-efficiency cabin air, or HECA, developed specifically for school buses reduced exposure to vehicular pollutants by up to 88 percent, according to a new paper. study by researchers at the UCLA Fielding School of Public Health. 

The HECA system could help protect the 25 million American children who commute on school buses nearly every day, according to the authors from the UCLA Fielding School of Public Health. Children are more susceptible to air pollution than adults because they breathe more quickly and their immune and cardiovascular systems are still developing, said Yifang Zhu, the study's senior author and an associate professor in the department of environmental health sciences.

Science Is Changing - And Sharply Segregated Expertise Is Obsolete

Science2.0 - March 3, 2015 - 2:45pm
The world's challenges demand science solutions - and fast - but it doesn't need the old style of detached experts, write a team of scientists in, ironically, one of America's most prominent and detached corporate science publications; Science magazine, a reputable legacy publication with a politician leading them.

Segregated expertise, like segregated articles of taxpayer-funded science, is obsolete.

Stage, Not Age - Knowing Your Child's Reading Ability And How To Help Them

Science2.0 - March 3, 2015 - 1:30pm

A child's reading progression isn't based on age, so you need to know what stage your child is up to in order to help them. Image credit:  Shutterstock

Learning to read is a complicated process and parents often wonder if their child is developing reading abilities at the rate they “should”. Research agrees, however, that reading (and writing) is very much a developmental process, which can look very different for different children, regardless of their age.

Why Nitrate Supplementation Increases Athletic Performance

Science2.0 - March 3, 2015 - 1:30pm
Amateur athletes are competitive and they are always looking for an advantage even if it isn't their careers, so it is no surprise that supplement stores are filled with promises of gains.

Nitrate supplements, claiming to  improve the efficiency at which muscles use oxygen, have been popular for years, but do they work? 

A new study says they may increase performance--they decrease the viscosity of blood, aiding in blood flow, while at the same time ensuring that tissue oxygen requirements are not compromised.
