Individuals who visit natural spaces weekly, and feel psychologically connected to them, report better physical and mental wellbeing, new research has shown. Alongside the benefits to public health, those who make weekly nature visits, or feel connected to nature, are also more likely to behave in ways which promote environmental health, such as recycling and […]

Monkey malaria breakthrough offers possible cure for relapsing malaria
A breakthrough in monkey malaria research by two University of Otago scientists could help scientists diagnose and treat a relapsing form of human malaria. Malaria is a mosquito-borne infectious disease that affects humans and other animals with more than 200 million cases annually, particularly in Asia, the Pacific and South America. Symptoms include fever, tiredness, […]
How much are we learning about the genome? Natural selection is science’s best critic
In 2003, the Human Genome Project revealed to the world the three billion chemical units within human DNA. Since that time, scientists have designed many ways to organize and assess this overwhelmingly large amount of information. Now, scientists at Cold Spring Harbor Laboratory (CSHL) have determined that evolution can help guide these efforts. Researchers have […]
Tree swallow study: Stressful events have long-term health impacts
Little is known about how brief yet acute stressors — such as war, natural disasters and terror attacks — affect those exposed to them, though human experience suggests they have long-term impacts. Two recent studies of tree swallows uncover long-term consequences of such passing but major stressful events. Both studies provide information on how major […]
Key factor may be missing from models that predict disease outbreaks from climate change: Parasites that incubate at higher temperatures cause stronger infections in future hosts, creating a climate ‘echo effect’ across generations of pathogens
New research from Indiana University suggests that computer models used to predict the spread of epidemics from climate change — such as crop blights or disease outbreaks — may not take into account an important factor in predicting their severity. A study recently published in the journal Ecology has found that pathogens that grow inside […]
Our human ancestors walked on two feet but their children still had a backup plan: Most complete foot of ancient human child ever
More than 3 million years ago, our ancient human ancestors, including their toddler-aged children, were standing on two feet and walking upright, according to a new study published in Science Advances. “For the first time, we have an amazing window into what walking was like for a 2½-year-old, more than 3 million years ago,” says […]
