Mystery orbits in outermost reaches of solar system not caused by 'Planet Nine'

EurekAlert! - Sáb, 01/19/2019 - 23:00
The strange orbits of some objects in the farthest reaches of our solar system, hypothesized by some astronomers to be shaped by an unknown ninth planet, can instead be explained by the combined gravitational force of small objects orbiting the sun beyond Neptune, say researchers.

EurekAlert! - Vie, 01/18/2019 - 23:00
An international team of researchers, including Professor Sarah Kang and DoYeon Kim in the School of Urban and Environmental Engineering at South Korea's Ulsan National Institute of Science and Technology (UNIST), has unveiled local drivers of amplified arctic warming.

UTA herpetologists describe new species of snake found in stomach of predator snake

EurekAlert! - Jue, 01/17/2019 - 23:00
Herpetologists at The University of Texas at Arlington have described a previously unknown species of snake that was discovered inside the stomach of another snake more than four decades ago.

Targeting 'hidden pocket' for treatment of stroke and seizure

EurekAlert! - Jue, 01/17/2019 - 23:00
By closely examining a special neuron receptor that is involved in memory, learning, and much more, researchers have identified a hidden molecular 'pocket.' By creating chemical compounds that affect this pocket only in very specific circumstances, they are one step closer to creating ideal treatments for stroke and seizures.

New technologies enable better-than-ever details on genetically modified plants

EurekAlert! - Jue, 01/17/2019 - 23:00
Salk researchers have mapped the genomes and epigenomes of genetically modified plant lines with the highest resolution ever to reveal exactly what happens at a molecular level when a piece of foreign DNA is inserted. Their findings, published in the journal PLOS Genetics on January 15, 2019, elucidate the routine methods used to modify plants, and offer new ways to more effectively minimize potential off-target effects.

Firsthand accounts indicate fentanyl test strips are effective in reducing overdose risk

EurekAlert! - Jue, 01/17/2019 - 23:00
Young adults who use drugs find fentanyl test strips useful, residue testing more convenient and testing at home more private, a Brown study found.

Using bacteria to create a water filter that kills bacteria

EurekAlert! - Jue, 01/17/2019 - 23:00
Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly -- and could provide clean water for those in need.

Liver cancer patients can be treated for Hep C infection

EurekAlert! - Jue, 01/17/2019 - 23:00
A large, multi-center study refutes earlier suggestions that antiviral drugs for treating hepatitis C may lead to a higher recurrence of liver cancer.

Researchers identify specific cognitive deficits in individuals with spinal cord injury

EurekAlert! - Jue, 01/17/2019 - 23:00
'People often focus on mobility impairments associated with SCI; however, addressing cognitive deficits in this population is also critically important,' said co-author Dr. Dyson-Hudson, director of SCI Research, and director of the Northern New Jersey SCI Model System. 'Future research needs to be based on broader measures of neuropsychological function. Identifying modifiable risk factors and developing targeted cognitive interventions will help restore maximal function, and support the efforts of individuals to participate in their communities and the workforce.'

'Happiness' exercises can boost mood in those recovering from substance use disorder

EurekAlert! - Jue, 01/17/2019 - 23:00
Brief, text-based, self-administered exercises can significantly increase in-the-moment happiness for adults recovering from substance use disorders, report researchers at the Massachusetts General Hospital Recovery Research Institute

Researchers discover synaptic logic for connections between two brain hemispheres

EurekAlert! - Jue, 01/17/2019 - 23:00
Researchers at the Max Planck Florida Institute for Neuroscience have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are arranged within a neuron's dendritic field.

Placentas adapt when mothers have poor diets or low oxygen during pregnancy

EurekAlert! - Jue, 01/17/2019 - 23:00
Cambridge researchers have discovered the placenta regulates how much oxygen and nutrients it transports to babies during challenging pregnancies in the first study of its kind. The placenta is one of the least understood human organs and it is notoriously difficult to study. This new research focused on analysing the placental mitochondria and it is hoped the new findings could lead to tests to determine whether a mother's placenta is functioning properly.

Bioengineering & Translational Medicine honors biotech pioneers Langer and Peppas

EurekAlert! - Jue, 01/17/2019 - 23:00
Bioengineering & Translational Medicine (BioTM), published by Wiley on behalf of the American Institute of Chemical Engineers (AIChE) and its Society for Biological Engineering (SBE), has released a tribute issue dedicated to research inspired by Robert Langer and Nicholas Peppas -- two biotechnology luminaries whose game-changing contributions to drug delivery and biomaterials have made those fields integral elements of modern chemical engineering research and education.

Does being bilingual make children more focused? Study says no

EurekAlert! - Jue, 01/17/2019 - 23:00
Bilingual children do not have more advantages than monolingual children when it comes to executive function, which includes remembering instructions, controlling responses, and shifting swiftly between tasks, according to a new study published in PLOS ONE.

Scientists discover natural fitness watch in fishes that records their activity levels

EurekAlert! - Jue, 01/17/2019 - 23:00
An international research team including scientists from the University of Southampton have shown for the first time that the energetic cost of living (the metabolic rate) of fish can be measured in structures that grow in their ears. This new tool can be used to show how fish are influenced by and adapt to changes in their environment, including climate change.
