Study: Forest resilience declines in face of wildfires, climate change

Mié, 12/13/2017 - 23:00
The research team said that with a warming climate, forests are losing their resilience to wildfires.

Journaling inspires altruism through an attitude of gratitude

Mié, 12/13/2017 - 23:00
Gratitude does more than help maintain good health. New research at the University of Oregon finds that regularly noting feelings of gratitude in a journal leads to increased altruism.

Robotics researchers track autonomous underground mining vehicles

Mié, 12/13/2017 - 23:00
QUT robotics researchers have developed new technology to equip underground mining vehicles to navigate autonomously through dust, camera blur and bad lighting.

Tracing a plant's steps: Following seed dispersal using chloroplast DNA

Mié, 12/13/2017 - 23:00
Researchers have developed a new tool to sequence chloroplast DNA from hundreds of plants at once, to learn more about how plant populations move. This tool, CallHap, makes it cheaper and easier to sequence the chloroplast genomes of large numbers of plants and accurately track seed dispersal across landscapes.

Forty years after first Ebola outbreak, survivors show signs they can stave off new infection

Mié, 12/13/2017 - 23:00
Survivors of the first known Ebola outbreak, which occurred in the Democratic Republic of the Congo in 1976, may be key to development of vaccines and therapeutic drugs to treat future outbreaks. UCLA researchers located the 14 Ebola survivors of the 1976 outbreak who, in January 2016, were still living in the same small, remote villages in the forests of the Équateur Province of northwestern Democratic Republic of the Congo.

High-intensity exercise delays Parkinson's progression

Mié, 12/13/2017 - 23:00
High-intensity exercise three times a week is safe for individuals with early-stage Parkinson's disease and decreases worsening of the disease's symptoms, according to results of a study published in the Dec. 11 issue of JAMA Neurology.

Synthetic protein packages its own genetic material and evolves

Mié, 12/13/2017 - 23:00
Scientists have created computationally designed protein assemblies, that display some functions normally associated with living things, in the search for ways to transport therapeutic cargo into specific types of cells without using viruses as vehicles. These encapsulate their own RNA genomes and evolve new traits in complex environments. They are synthetic versions of the protein shells that viruses use to protect and deliver materials. The synthetic proteins evolved better RNA packaging, resistance against degrading enzymes in blood and longer circulation time.

Exercise does not seem to increase bone marrow edema in healthy people

Mié, 12/13/2017 - 23:00
A recent study published in Rheumatology finds that osteitis/bone marrow edema as measured by magnetic resonance imaging was present in healthy people. However, it did not increase significantly due to intense physical activity.

MIT scientists prove tailgating doesn't get you there faster

Mié, 12/13/2017 - 23:00
A team from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) shows that we'd have fewer traffic jams if we stopped tailgating.

Eating together as a family helps children feel better, physically and mentally

Mié, 12/13/2017 - 23:00
Children who routinely eat their meals together with their family are more likely to experience long-term physical and mental health benefits, a new Canadian study shows.

Student drug use in Ontario, Canada, at historic lows but new concerns over fentanyl emerge

Mié, 12/13/2017 - 23:00
By almost every measure, students in grades 7 through 12 in Ontario, Canada are drinking, smoking, and using drugs at the lowest rates since the Ontario Student Drug Use and Health Survey (OSDUHS) began in 1977. This according to new numbers released today by the Centre for Addiction and Mental Health (CAMH). But new data on fentanyl use, included for the first time in this survey, is raising concerns given the health risks of this potent opioid drug.

ASU scientists develop new, rapid pipeline for antimicrobials

Mié, 12/13/2017 - 23:00
The research arm of the U.S. Department of Defense, the Defense Advanced Research Program Agency, or DARPA, is known for taking on out-sized challenges. And so, they put out a call for researchers to figure out how to make at least 1000 doses to an unknown pathogen - in a week. An ASU team was one of the few that rose to this challenge.

Groundbreaking gene therapy trial set to cure hemophilia

Mié, 12/13/2017 - 23:00
A 'cure' for hemophilia is one step closer, following results of a groundbreaking gene therapy trial led by Queen Mary University of London and the NHS in London.

Autism traits increase thoughts of suicide in people with psychosis

Mié, 12/13/2017 - 23:00
People with autism traits who have psychosis are at a greater risk of depression and thoughts of suicide, new research has found.

Vaping popular among teens; opioid misuse at historic lows

Mié, 12/13/2017 - 23:00
Nearly one in three 12th-graders report past year use of some kind of vaping device, raising concerns about the impact on their health. What they say is in the device, however, ranges from nicotine, to marijuana, to 'just flavoring.' The survey also suggests that use of hookahs and regular cigarettes is declining. These findings come from the 2017 Monitoring the Future (MTF) survey of eighth, 10th and 12th graders in schools nationwide, reported today by NIDA, along with scientists from the University of Michigan.

Lizards of Oz take toll on turtle eggs

Mar, 12/12/2017 - 23:00
Goannas have overtaken foxes as the number one predator of the endangered loggerhead turtle at its second largest Queensland nesting beach.A University of Queensland study has found that since feral red foxes were controlled in the 1980s, there has been an increase in the number goanna raids on loggerhead turtle nests at Wreck Rock beach, south of Agnes Waters.

Robotics researchers track autonomous underground mining vehicles

Mar, 12/12/2017 - 23:00
QUT robotics researchers have developed new technology to equip underground mining vehicles to navigate autonomously through dust, camera blur and bad lighting. Using mathematics and biologically-inspired algorithms, the technology uses vehicle-mounted cameras to track the location of the vehicle in underground tunnels to within meters.

Novel fMRI applications in childhood epilepsy increase understanding of seizure impacts

Mar, 12/12/2017 - 23:00
Functional magnetic resonance imaging (fMRI) has allowed researchers to map the memory functions that are often impaired within the brains of children with epilepsy. Additionally, a separate study of a novel application of resting-state fMRI, where the patient does not have to complete tasks, demonstrated the potential for clinicians to use noninvasive fMRI for language assessment for children who are too young or impaired to follow task directions in traditional fMRI studies.

Doing without dark energy

Mar, 12/12/2017 - 23:00
Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of 'dark energy.' Einstein's original equations for General Relativity actually predict cosmic acceleration due to an 'instability,' they argue in paper published recently in Proceedings of the Royal Society A.

Breathing exercises help asthma patients with quality of life

Mar, 12/12/2017 - 23:00
A study led by the University of Southampton has found that people who continue to get problems from their asthma, despite receiving standard treatment, experience an improved quality of life when they are taught breathing exercises.
