Ottawa, Mar. 5, 2019 - Two Canadian biologists are proposing a better way to assess the conservation value of old-growth forests in North America--using lichens, sensitive bioindicators of environmental change.
Dr. Troy McMullin, lichenologist at the Canadian Museum of Nature, and Dr. Yolanda Wiersma, landscape ecologist at Memorial University of Newfoundland, propose their lichen-focussed system in a paper published today in the Ecological Society of America journal, Frontiers in Ecology and the Environment.
TAMPA, Fla. (March 5, 2019)- More than 50 children died in hot cars in 2018, making it the deadliest year on record. Many of the cases involve parents who unknowingly left a child behind, often for an entire day. University of South Florida Psychology Professor David Diamond has studied this phenomenon for over a decade and has served as an expert witness on many high-profile cases. In his latest publication, he describes the psychological and neural basis of how responsible people make such fatal errors.
Incorporating the arts--rapping, dancing, drawing--into science lessons can help low-achieving students retain more knowledge and possibly help students of all ability levels be more creative in their learning, finds a new study by Johns Hopkins University.
The findings were published on Feb. 7 in Trends in Neuroscience and Education and support broader arts integration in the classroom.
Outbreaks of mosquito-borne illnesses like yellow fever, dengue, Zika and chikungunya are rising around the world. Climate change has created conditions favorable to mosquitoes' spread, but so have human travel and migration and accelerating urbanization, creating new mini-habitats for mosquitoes.
There is broad support for building health care systems that are patient centered, seen as a means of improving health outcomes and as morally worthy in itself. But the concept of patient-centered care has increasingly merged with the concept of patients as consumers, which "is conceptually confused and potentially harmful," write Michael K.
Alien species are the main driver of recent extinctions in both animals and plants, according to a new study by UCL researchers.
They found that since 1500, alien species have been solely responsible for 126 extinctions, 13% of the total number studied.
Of 953 global extinctions, 300 happened in some part because of alien species, and of those 300, 42% had alien species alone listed as the cause of their demise.
It's time to strengthen support for the 28% of people who provide care for an ageing family member, friend or neighbour in Canada, argues an editorial in CMAJ (Canadian Medical Association Journal).
"Our ability to support informal caregiving remains one of Canada's most pressing health care and societal issues," says Dr. Nathan Stall, associate editor, CMAJ.
Using steroids during cardiopulmonary bypass surgery did not reduce the risk of acute kidney injury in people at increased risk of death, according to a study conducted in 18 countries published in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.181644.
March 4, New Delhi: Living in districts with air pollution from intense crop residue burning (CRB) is a leading risk factor for acute respiratory infection (ARI), especially among children less than five years, in northern India. Additionally, CRB also leads to an estimated economic loss of over USD 30 billion annually. These are the key findings of a new study from researchers at the International Food Policy Research Institute (IFPRI) and partner institutes. The study estimates--for the first time--the health and economic costs of CRB in northern India.
Malaga, Spain - 3 March 2019: Heart attack patients taken directly to heart centres for lifesaving treatment have better long-term survival than those transferred from another hospital, reports a large observational study presented today at Acute Cardiovascular Care 20191 a European Society of Cardiology (ESC) congress. Directly admitted patients were older, suggesting that heart attacks in young adults, and particularly women, go unrecognised by paramedics and patients.
Malaga, Spain - 3 March 2019: Women call an ambulance for husbands, fathers and brothers with heart attack symptoms but not for themselves. "It's time for women take care of themselves too" is the main message of two studies from the Polish Registry of Acute Coronary Syndromes (PL-ACS) presented today at Acute Cardiovascular Care 20191,2 a European Society of Cardiology (ESC) congress.
Malaga, Spain - 2 March 2019: Don't ignore heart attack symptoms while travelling, keep emergency numbers at hand. That's the main message of a study presented today at Acute Cardiovascular Care 20191 a European Society of Cardiology (ESC) congress. Cardiovascular disease is the leading cause of natural death among people who are travelling, yet, so far, the long-term outlook for those who have a heart attack while on a trip is unknown.
CORVALLIS, Ore. - Chemical processes that are more efficient and less expensive may be coming to industries ranging from battery manufacturing to detergent production thanks to an Oregon State University researcher's work advancing metal oxides as catalysts.
The findings, by a collaboration that included scientists from the University of Delaware, were published in Nature Catalysis.
BALTIMORE, MD., March 1 -- Researchers at the University of Maryland School of Medicine have discovered a mechanism for how androgens -- male sex steroids -- sculpt brain development. The research, conducted by Margaret M. McCarthy, Ph.D., who Chairs the Department of Pharmacology, could ultimately help researchers understand behavioral development differences between males and females.
Cold Spring Harbor, NY -- The ability to comprehensively map the architecture of connections between neurons in primate brains has long proven elusive for scientists. But a new study, conducted in Japan with contributing neuroscientists from Cold Spring Harbor Laboratory (CSHL), has resulted in a 3D reconstruction of a marmoset brain, as well as information about neuronal connectivity across the entire brain, that offers an unprecedented level of detail.
