A potential setback in the personalized medicine of cancer

EurekAlert! - Lun, 04/16/2018 - 22:00
One of the most constant and exhaustive searches in cancer research is for a treatment aimed specifically at the Ras family of genes, the most common oncogenes and those that initiate many of the most lethal tumors. However, the results of this hypothetical treatment may be far less positive than speculated due to a manuscript published by the Genomic Instability Group at the Spanish National Cancer Research Centre (CNIO).

Mother's depression might do the same to her child's IQ

EurekAlert! - Lun, 04/16/2018 - 22:00
Roughly one in 10 women in the United States will experience depression, according to the Centers for Disease Control and Prevention. The consequences, however, may extend to their children, report researchers at University of California San Diego School of Medicine, who found that a mother's depression can negatively affect a child's cognitive development up to the age of 16. The findings are published in the April issue of Child Development.

'Striosome' neurons in the basal ganglia play a key role in learning

EurekAlert! - Dom, 04/15/2018 - 22:00
Researchers at OIST have successfully isolated and recorded the activity of a subset of neurons in the striatum in the brain, shedding light on one mechanism underlying learning and decision making in animals.

Portland State researchers chart a new way to look at concussion

EurekAlert! - Dom, 04/15/2018 - 22:00
A Portland State University research team studying concussion has published an interactive diagram showing the many facets of mild traumatic brain injury (TBI) -- from sleep problems to mood disorders to the increased danger of dementia -- and how they connect with and affect each other.

Using AI to detect heart disease

EurekAlert! - Dom, 04/15/2018 - 22:00
Predicting and monitoring cardiovascular disease is often expensive and tenuous, involving high-tech equipment and intrusive procedures. However, a new method developed by researchers at USC Viterbi School of Engineering offers a better way. By coupling a machine learning model with a patient's pulse data, they are able to measure a key risk factor for cardiovascular diseases and arterial stiffness, using just a smart phone.

Horses can breathe easier thanks to new treatment for degenerative respiratory condition

EurekAlert! - Dom, 04/15/2018 - 22:00
Morris Animal Foundation-funded researchers have developed a new surgical technique for recurrent laryngeal neuropathy (RLN) that is improving outcomes and helping horses breathe a little bit easier.

Huge variation in prescribing practice for gluten-free foods in England

EurekAlert! - Dom, 04/15/2018 - 22:00
Prescribing practice for gluten-free foods in England varies hugely, and doesn't seem to be driven by obvious medical factors, reveals research published in the online journal BMJ Open.

Regular nut intake linked to lower risk of heart rhythm irregularity (atrial fibrillation)

EurekAlert! - Dom, 04/15/2018 - 22:00
Eating several servings of nuts every week may help lower the risk of developing the heart rhythm irregularity, atrial fibrillation, also known as heart flutter, finds research published online in the journal Heart.

Hello DARKNESS

UCSB physicists team up with Caltech astronomers to commission the most advanced camera in the world.

From insulator to conductor in a flash

EurekAlert! - Dom, 04/15/2018 - 22:00
A clever combination of novel technologies enables us to study promising materials for the electronics of tomorrow.Using short laser pulses, a research team led by Misha Ivanov of the Max Born Institute in Berlin together with scientists from the Russian Quantum Center in Moscow have now shed light on the extremely rapid processes taking place within novel materials. Their results have appeared in the prestigious journal "Nature Photonics".

Mosquitoes reveal fatal attraction

EurekAlert! - Dom, 04/15/2018 - 22:00
Malaria causes the bodies of its human hosts to emit specific odors from the skin that make the hosts even more attractive to mosquitoes, which invites further bites and risks infection of more mosquitoes and wider transmission of the disease. It's a vicious circle but one that has enabled researchers to identify the odors as organic hydrocarbons whose discovery could bring relief to a disease that claimed nearly half a million lives in 2016.

Oregon scientists decipher the magma bodies under Yellowstone

EurekAlert! - Dom, 04/15/2018 - 22:00
Using supercomputer modeling, University of Oregon scientists have unveiled a new explanation for the geology underlying recent seismic imaging of magma bodies below Yellowstone National Park.

Warming climate could speed forest regrowth in eastern US

EurekAlert! - Dom, 04/15/2018 - 22:00
Warming climate could speed the natural regrowth of forests on undeveloped or abandoned land in the eastern United States, according to a new study. Previous research has shown that the succession from field to forest can happen decades sooner in the southeastern US than in the Northeast. But it wasn't obvious why. A new study points to temperature as the major factor influencing the pace of reforestation.

Elevation in buildings can affect the decisions we make

EurekAlert! - Dom, 04/15/2018 - 22:00
New research shows that elevation in an office building can increase someone's willingness to take financial risks because it makes people feel more powerful.

Regional health system growth and implications for stroke care

EurekAlert! - Dom, 04/15/2018 - 22:00
New research shows that stroke patients are increasingly being transferred out of smaller community and rural hospitals and sent to larger medical centers for their care and rehabilitation. While this is a positive sign for patients who need more advanced treatments, the trend has drawbacks in terms of cost and points to the need to improve the coordination of care between hospitals.

When three months from now feels right around the corner

EurekAlert! - Dom, 04/15/2018 - 22:00
If you've ever noticed yourself thinking about the timing of a plan in two opposing ways - something that feels longer off than your actual time calculation -- you're on to something. New research shows our different ways of estimating time don't necessarily move in lock-step.

Volunteering 2 hours per week reduces loneliness in widowed older adults, study finds

EurekAlert! - Dom, 04/15/2018 - 22:00
Widowed older adults can reduce the loneliness that results from the death of a spouse by volunteering 100 hours per year, which is about two hours per week, according to a recent study.

Music intensifies effects of anti-hypertensive medication

EurekAlert! - Dom, 04/15/2018 - 22:00
A research shows anti-hypertensive drugs improving heart rate more in patients who listen to music after taking medication. Among musical genres, classical music is the one with greatest efficiency at reducing arterial pressure; Brazilian authors of the study speculate whether music acts on the patients' parasympathetic system, increasing their capability of absorbing medication.

First an alga, then a squid, enigmatic fossil is actually a fish

EurekAlert! - Dom, 04/15/2018 - 22:00
A fossil slab discovered in Kansas 70 years ago and twice misidentified -- first as a green alga and then as a cephalopod -- has been reinterpreted as the preserved remains of a large cartilaginous fish, the group that includes sharks and rays. In a study published in the Journal of Paleontology, American Museum of Natural History researchers describe the fishy characteristics of the animal, which lived between 70-85 million years ago.
