Burgess Shale Fossil Site Gives Up Oldest Evidence Of Brood Care

Burgess Shale Fossil Site Gives Up Oldest Evidence Of Brood Care

FOR RELEASE from the UNIVERSITY OF TORONTO
TORONTO, ON - Long before kangaroos carried their joeys in their pouches and honey bees nurtured their young in hives, there was the 508-million-year-old Waptia. Little is known about the shrimp-like creature first discovered in the renowned Canadian Burgess Shale fossil deposit a century ago, but recent analysis by scientists from the University of Toronto, Royal Ontario Museum, and Centre national de la recherche scientifique has uncovered eggs with embryos preserved within the body of the animal. It is the oldest example of brood care in the fossil record.

Stem Cells Likely To Be Safe For Use In Regenerative Medicine

Stem Cells Likely To Be Safe For Use In Regenerative Medicine

Researchers say they have found the strongest evidence to date that human pluripotent stem cells -- cells that can give rise to all tissues of the body -- will develop normally once transplanted into an embryo.
Pluripotent stem cells for use in regenerative medicine or biomedical research come from two sources: embryonic stem cells, derived from fertilized egg cells; and induced pluripotent stem cells, where skin cells are 'reset' to their original form. The promise (bordering on hype in the case of human embryonic stem cells, with promises a decade ago of curing Alzheimer's if they just got more money) is that they might repair various organs and tissues, particularly those that have poor regenerative capacity, such as the heart, brain and pancreas. 

High Fat/low Carb Diet Could Combat Schizophrenia

High Fat/low Carb Diet Could Combat Schizophrenia

Research by James Cook University scientists has found a diet favoured by body-builders may be effective in treating schizophrenia.
Associate Professor Zoltan Sarnyai and his research group from JCU's Australian Institute of Tropical Health and Medicine (AITHM) have discovered that feeding mice a ketogenic diet, which is high on fat but very low on carbohydrates (sugars), leads to fewer animal behaviours that resemble schizophrenia.
The ketogenic diet has been used since the 1920s to manage epilepsy in children and more recently as a weight loss diet preferred by some body builders.

Men Actually Recommend Getting Help For Depression

Men Actually Recommend Getting Help For Depression

History supports Dwayne 'The Rock' Johnson's recent tweet saying that men have a hard time asking for help for their depression.
But new research brings good news: Men really do think it's important to seek help.
Participants in a national survey read a scenario describing someone who had depressed symptoms. Among other things, this hypothetical person has difficulty sleeping, can't concentrate and doesn't feel happy even when good things happen.
The survey then asked participants to rate the importance of getting help from friends, family members or religious leaders. Men overall rank this as a 7.7 on an importance scale of 1-10, which is surprising because that ranking is just as high as what women said to the survey.

Fungi May Help Drought-stressed Wheat

Fungi May Help Drought-stressed Wheat

Scientists at Aarhus University have discovered that fungi associated with plant roots may improve growth and yield of drought-stressed wheat.
Water scarcity has a negative impact on wheat production. As a consequence of exposure to drought, crops show poorer growth and lower yield. This is a serious problem as the predicted increase in frequency of extreme climate episodes will lead to multiple drought conditions during crop growth which in turn will reduce the yield of wheat, one of the world's most important foods.
The UN Intergovernmental Panel on Climate Change predicts that drought stress in crops will become increasingly serious in the future. Globally, wheat yield is only 30-60 percent of its potential.

Organic Soils Increase Greenhouse Gas Emissions

Organic Soils Increase Greenhouse Gas Emissions

It's no secret that the organic growing process is harder on the environment, with more toxic pesticides, less efficient use of the land, and lower yields, but some practices are exceptionally harmful, like growing crops in organic (peat) soil. 
When organic soils are drained and cultivated the organic matter in the soil will decompose which leads to emissions of greenhouse gases, finds a study in Denmark, and that makes up as much as 6 percent of Denmark's total greenhouse gas emissions.

Growing Diversity In Doctoral Programs

Growing Diversity In Doctoral Programs

Students can feel isolated and pressure to represent all minorities

It is difficult to talk about discrimination, stereotyping and microaggression

Guidance from diverse coaches, peers spurs students' persistence to pursue academic careers

"I'm so happy to see other people of color in one place doing the same thing that I'm doing."
CHICAGO --- The challenges of increasing diversity in academia have been widely cited. Now a new Northwestern Medicine study is addressing challenges at the Ph.D. level to boost the persistence of underrepresented minority and female students toward academic careers.

Fish Oil Helps Transform Fat Cells From Storage To Burning

Fish Oil Helps Transform Fat Cells From Storage To Burning

Kyoto, Japan -- Researchers have found that fish oil transforms fat-storage cells into fat-burning cells, which may reduce weight gain in middle age.
The team explains in Scientific Reports that fish oil activates receptors in the digestive tract, fires the sympathetic nervous system, and induces storage cells to metabolize fat.
Fat tissues don't all store fat. So-called "white" cells store fat in order to maintain energy supply, while "brown" cells metabolize fat to maintain a stable body temperature. Brown cells are abundant in babies but decrease in number with maturity into adulthood.

Largest Ever Ovarian Cancer Trial First Evidence That Screening Saves Lives

Largest Ever Ovarian Cancer Trial First Evidence That Screening Saves Lives

One of the popular myths that lazy journalists like to "debunk" this time of year is that early cancer detection saves lives. That's because there is no way to really prove someone didn't die, any more than it is possible for a politician to claim that a giant pork stimulus packing for government union employees saved jobs.
A lazy narrative like 'early detection doesn't save lives' means people will think that about all things, and they may not go to a doctor until they have a giant tumor growing out of them.

Composting Food Waste: Good For Self-Identification And Maybe For The Environment

Composting Food Waste: Good For Self-Identification And Maybe For The Environment

In the 1980s, the recycling debate was all the rage, with arguments for and against government doing it. The argument against government doing it was predictable; government is inefficient and expensive and the landfills waiting for a recycling list that would grow with every environmental lobbying effort would be the size of regular landfills.
Government recycling won and now there are giant landfills of recycling material that can never actually be recycled - all those glossy magazine pages with perfume on them, for example. Most of California recycling is actually done in China, after being shipped there in emissions-belching boats.

Allantoin Face Cream Ingredient Mimics Effects Of Caloric Restriction Diet

Allantoin Face Cream Ingredient Mimics Effects Of Caloric Restriction Diet

A commonly used skin care ingredient is one of several newly identified compounds that can mimic the life-extending effect of a starvation diet, finds a new lab study.
Calorie restriction, a dramatic reduction in calorie intake, has been found to slow down the aging process in several animal models. Mice weaned on it from birth live longer but to-date it has not been shown to work in humans, since such an experiment on babies would be a human rights violation. Efforts are on to try and create drugs that can reproduce this effect, without the side effects of starvation.
