States with more permissive gun laws and greater gun ownership have higher rates of mass shootings, and a growing divide is emerging between states with restrictive versus permissive gun laws. According to a new study, researchers at Columbia Mailman School of Public Health found that in most years permissive states had higher mass shooting rates compared to restrictive states.

Scientists are urging for improved regulation on pesticides after finding that they affect genes in bumblebees, according to research led by Queen Mary University of London in collaboration with Imperial College London.

For the first time, researchers applied a biomedically inspired approach to examine changes in the 12,000 genes that make up bumblebee workers and queens after pesticide exposure.

The study, published in Molecular Ecology, shows that genes which may be involved in a broad range of biological processes are affected.

Too much time in front of the bedroom TV deprives the child of more enriching developmental activities and may explain, in part, less optimal body mass, poor eating habits and socio-emotional difficulties as a teenager, says the study, published Dec. 26 in Pediatric Research.

"The early years are a critical period in a child's development," said study author Linda Pagani, a professor at UdeM's School of Psycho-Education, who will be discussing her study today at the International Convention of Psychological Science, in Paris.

Researchers at the Joint Quantum Institute (JQI) have implemented an experimental test for quantum scrambling, a chaotic shuffling of the information stored among a collection of quantum particles.

Demand for science, technology, engineering and math (STEM) degrees is on the rise. However, there are many barriers to gaining one.

One may be the appearance of the student seeking the degree, according to a new Rice University study. The extent to which students look racially stereotypical - that is, more or less like members of their racial group - influences how likely they are to persist in a STEM-related field.

Cold Spring Harbor, NY - It's no secret that our genes are what makes us... us! But genes are often also the basis for debilitating diseases. One of the major clues to understanding any illness is seeing which genes are acting unusually during disease onset. But it's not often clear if unusual gene activity is unique to the disease at hand, or is merely a more general symptom of an unhealthy body. Now, scientists at Cold Spring Harbor Laboratory (CSHL) have crafted a ranked list of usual suspects that could prove invaluable for researchers and clinicians.

BOSTON, MA - Daily bathing with an antiseptic soap, plus nasal ointment for patients with prior antibiotic resistant bacteria, reduced hospital acquired infections among patients with central venous catheters and other devices that pierce the skin, according to results of the ABATE Infection Trial. The trial was a 53 hospital randomized trial involving approximately 340,000 patients led by researchers from the Harvard Pilgrim Health Care Institute, the University of California Irvine, Rush University and HCA Healthcare (HCA).

Those of us who drive regularly are keenly aware of gas prices and their daily fluctuations. Many of the factors that influence the price per gallon -- the cost of crude oil, regional taxes and processing and transportation charges -- affect all pumps in a given area. Why then do some stations charge more for fuel than others in the same general geographic location?

An Australian study of more than 1200 women has found regular phone calls between first time mothers and other volunteer mothers with previous breastfeeding experience may be the key to boosting national breastfeeding rates.

La Trobe University and the Royal Women's Hospital's Ringing Up about Breastfeeding EarlY (RUBY) trial involved more than 1000 new mothers from the Women's, Monash and Sunshine hospitals, and 230 women with personal breastfeeding experience who volunteered to become telephone support peers.

Using computer simulations and 3D models, palaeontologists from the University of Bristol have uncovered more detail on how Mesozoic sea dragons swam.

The research, published today in the journal Proceedings of the Royal Society B, sheds new light on their energy demands while swimming, showing that even the first ichthyosaurs had body shapes well adapted to minimise resistance and maximise volume, in a similar way to modern dolphins.

Ichthyosaurs are an extinct group of sea-going reptiles that lived during the Mesozoic Era, around 248-93.9 million years ago.

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.
