New computational tool harnesses big data, deep learning to reveal dark matter of the transcriptome

EurekAlert! - Dom, 03/24/2019 - 22:00
A research team at Children's Hospital of Philadelphia has developed an innovative computational tool offering researchers an efficient method for detecting the different ways RNA is pieced together (spliced) when copied from DNA. Because variations in how RNA is spliced play crucial roles in many diseases, this new analytical tool will provide greater capabilities for discovering disease biomarkers and therapeutic targets, even from RNA-sequencing data sets with modest coverage.

Study suggests trees are crucial to the future of our cities

EurekAlert! - Dom, 03/24/2019 - 22:00
The shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a profound cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our towns and cities cool.

The largest delta plain in Earth's history

EurekAlert! - Dom, 03/24/2019 - 22:00
The largest delta plain in Earth's history formed along the northern coast of the supercontinent Pangea in the late Triassic. Its size out-scales modern counterparts by an order of magnitude, and approximates 1 percent of the total land area of the modern world. And although contenders are found in the rock record, no ancient counterpart exceeds the extent of the Triassic delta plain mapped in the subsurface Barents Sea either.

New virtual reality tool allows you to see the world through the eyes of a tiny primate

EurekAlert! - Dom, 03/24/2019 - 22:00
Imagine that you live in the rainforests of Southeast Asia, you're a pint-sized primate with enormous eyes and you look a little like Gizmo from the movie, 'Gremlins.' You're a tarsier -- a nocturnal animal whose giant eyes provide you with exceptional visual sensitivity, enabling a predatory advantage. A new virtual reality (VR) software, Tarsier Goggles, developed at Dartmouth College, simulates a tarsier's vision and illustrates the adaptive advantage of this animal's oversized eyes.

UMD-Led researchers' wood-based technology creates electricity from heat

EurekAlert! - Dom, 03/24/2019 - 22:00
A University of Maryland-led research team has developed a flexible, wood-based membrane that someday could turn body heat into electricity.

New in Ethics & Human Research, March-April 2019

EurekAlert! - Dom, 03/24/2019 - 22:00
Anticipatory waivers of consent for pediatric biobanking, a case study of unethical US experiments in Guatemala, and more in the current issue of Ethics & Human Research.

Restoring this enzyme's function protects against heart disease in lupus and beyond

EurekAlert! - Dom, 03/24/2019 - 22:00
Patients with lupus are at increased risk of heart disease. Exposing endothelial cells -- known to protect against heart disease, in part by producing nitric oxide -- to the serum of patients with lupus decreased nitric oxide production. Administering L-sepiapterin restored that production. These findings, reported by Medical University of South Carolina researchers in Lupus Science & Medicine, provide proof-of-concept that the enzyme is a promising therapeutic target for heart disease in lupus and beyond.

Discrimination, PTSD may lead to high preterm-birth rates among African-American women

EurekAlert! - Dom, 03/24/2019 - 22:00
African-American women are nearly twice as likely to give birth prematurely as white women. Amelia Gavin, an associate professor in the University of Washington School of Social Work, connects preterm birth to racial discrimination via PTSD.

Replacing sitting time with physical activity associated with lower risk of death

EurekAlert! - Dom, 03/24/2019 - 22:00
For those who get the least amount of physical activity, replacing a half hour of sitting time with physical activity was associated with up to a nearly 50 percent reduction in mortality, according to a new study from the American Cancer Society

Satellite tracks Tropical Cyclone Veronica along Australia coast

EurekAlert! - Dom, 03/24/2019 - 22:00
On March 25, 2019 Tropical Cyclone Veronica continued to move in southerly direction along the coast of Western Australia in the Southern Indian Ocean. NASA-NOAA's Suomi NPP satellite provided a visible image of the storm.

Matter waves and quantum splinters

EurekAlert! - Dom, 03/24/2019 - 22:00
Physicists in the United States, Austria and Brazil have shown that shaking ultracold Bose-Einstein condensates can cause them to either divide into uniform segments or shatter into unpredictable splinters, depending on the frequency of the shaking.

Model learns how individual amino acids determine protein function

EurekAlert! - Dom, 03/24/2019 - 22:00
A machine-learning model from MIT researchers computationally breaks down how segments of amino acid chains determine a protein's function, which could help researchers design and test new proteins for drug development or biological research.

NASA finds heavy rainfall around Tropical Cyclone Joaninha's center

EurekAlert! - Dom, 03/24/2019 - 22:00
NASA calculated the rainfall rates occurring in Tropical Cyclone Joaninha as it moved through the open waters of the Southern Indian Ocean.

Abused kids use text-based services to seek help, study shows

EurekAlert! - Dom, 03/24/2019 - 22:00
Minors aren't just using crisis services to report suicidal thoughts and depression -- they're using them to report abuse, a new study shows.

The stroke care paradox: Close-knit social networks increase delays in hospital arrival

EurekAlert! - Dom, 03/24/2019 - 22:00
Patients with closer-knit social networks, including family members and spouses, were more likely to delay seeking hospital care for a stroke whereas those with a more dispersed network of acquaintances were more likely to seek care faster.

The most aggressive spider societies are not always the ones that flourish

EurekAlert! - Dom, 03/24/2019 - 22:00
Evolutionary biologists at McMaster University who study the social lives and behaviour of colony spiders -- some of which are docile, others aggressive -- have found that the success of their cooperative societies depend on their neighbours.

Crisis management: When your celebrity advertising endorser generates negative publicity

EurekAlert! - Dom, 03/24/2019 - 22:00
Researchers from the University of Connecticut and Free University of Berlin published new research in the INFORMS journal Management Science that provides companies with substantiated, actionable insights on strategies for effectively responding to situations where their highly compensated celebrity endorsers generate negative publicity.

Study suggests how, when to support military couples after homecoming

EurekAlert! - Dom, 03/24/2019 - 22:00
Military couples look forward to joyful reunions after long deployments, but difficulties may lie ahead. A study with more than 500 couples in the months after homecoming offers guidance on how and when to help. University of Illinois communication professor Leanne Knobloch, the lead author, notes that military couples are "incredibly resilient," and military branches offer support services, but the study results may help with the design of resources and programs.

Race at the edge of the Sun: Ions are faster than atoms

EurekAlert! - Dom, 03/24/2019 - 22:00
Ions move faster than atoms in the gas streams of a solar prominence. Scientists at the University of Göttingen, the Institut d'Astrophysique in Paris and the Istituto Ricerche Solari Locarno have observed this. The results of the study were published in The Astrophysical Journal.

Listening to the quantum vacuum

EurekAlert! - Dom, 03/24/2019 - 22:00
Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of tools and technology used by gravitational wave scientists. Physicists at Louisiana State University measure quantum "back action" in the audio band at room temperature.
