Transporting spin: A graphene and boron nitride heterostructure creates large spin signals

EurekAlert! - Lun, 08/14/2017 - 22:00
Graphene Flagship scientists based at the University of Groningen, The Netherlands, have created a device based on a blilayer of graphene and boron nitride which shows unprecedented spin transport efficiency at room temperature. Highlighting the potential of creating devices containing graphene and related materials, the spin signal measured here is so large that it can be used in real life applications such as spin based logic and transistors.

Plant-produced polio vaccines could help eradicate age old disease

EurekAlert! - Lun, 08/14/2017 - 22:00
Plants have been used to produce a new vaccine against poliovirus in what is hoped to be a major step towards global eradication of the disease.

Prematurity leaves distinctive molecular signature in infants' cerebellum

EurekAlert! - Lun, 08/14/2017 - 22:00
Premature birth, which affects one in 10 US babies, is associated with altered metabolite profiles in the infants' cerebellum, the part of the brain that controls coordination and balance, a team led by Children's National Health System clinician-researchers report Aug. 15, 2017, in Scientific Reports.

Artificial blood vessels mimic rare accelerated aging disease

EurekAlert! - Lun, 08/14/2017 - 22:00
Biomedical engineers have grown miniature human blood vessels using stem cells taken from patients with an extremely rare genetic disease called progeria that causes symptoms resembling accelerated aging in children. The blood vessels exhibit many of the symptoms and drug reactions associated with progeria and will help doctors and researchers screen potential therapeutics for the disease, and other rare diseases, more rapidly.

Adult brains produce new cells in previously undiscovered area

EurekAlert! - Lun, 08/14/2017 - 22:00
A University of Queensland discovery may lead to new treatments for anxiety, depression and post-traumatic stress disorder (PTSD). UQ Queensland Brain Institute scientists have discovered that new brain cells are produced in the adult amygdala, a region of the brain important for processing emotional memories. Disrupted connections in the amygdala, an ancient part of the brain, are linked to anxiety disorders such as PTSD. The research marked a major shift in understanding the brain's ability to adapt and regenerate.

Human intrusion on fruit bat habitats raises exposure risk to Hendra virus in Australia

EurekAlert! - Lun, 08/14/2017 - 22:00
There is a rising risk of human and domestic animal exposure to deadly Hendra virus (HeV) carried by fruit bats in Eastern Australia due to human intrusion into their habitats, human proximity to woodlands and vegetation loss, a new study reveals.

Development of local food systems help bridge gap among people with different views

EurekAlert! - Lun, 08/14/2017 - 22:00
Work by a University of Kansas researcher shows that the development of local food systems in Kansas and Missouri could help bridge ideological gaps, especially as the process of sharing sustainable farming knowledge.

Kansas well owners, non-well owners have different watering routines during droughts

EurekAlert! - Lun, 08/14/2017 - 22:00
A University of Kansas researcher who examines water conservation policy and the habits of well owners in Kansas found that well owners are more likely to found that well ownership is significantly correlated to increased watering during droughts.

Understanding alternative reasons for denying climate change could help bridge divide

EurekAlert! - Lun, 08/14/2017 - 22:00
An early look at ongoing work by a University of Kansas researcher examines alternative reasons for climate change denial, specifically economic, social or cultural influences on why individuals or entire communities remain skeptical of climate change.

Immigrant detention centers referred to as family centers, but resemble prisons

EurekAlert! - Lun, 08/14/2017 - 22:00
University of Kansas researchers in interviews with attorneys found immigrant detention complexes function like jails and prisons.

Unique imaging of a dinosaur's skull tells evolutionary tale

EurekAlert! - Lun, 08/14/2017 - 22:00
Researchers using Los Alamos' unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.

An immune signaling pathway for control of Yellow Fever Virus infection

EurekAlert! - Lun, 08/14/2017 - 22:00
Princeton University researchers have uncovered a critical role for a new immune signaling pathway in controlling infection by the flavivirus Yellow Fever Virus (YFV).

Genome sequencing method can detect clinically relevant mutations using 5 CTCs

EurekAlert! - Lun, 08/14/2017 - 22:00
Whole genome sequencing using long fragment read (LFR), a technology that can analyze the entire genomic content of small numbers of cells, detected potentially targetable mutations using only five circulating tumor cells (CTCs) in a patient with metastatic breast cancer.
