Prehistoric mummy reveals ancient Egyptian embalming 'recipe' was around for millennia

EurekAlert! - Mar, 08/14/2018 - 22:00
The ancient Egyptians developed sophisticated embalming treatments far earlier and across a wider geographical area than had been previously known, forensic tests on a well-known prehistoric mummy have revealed.

Mapping the future direction for quantum research

EurekAlert! - Mar, 08/14/2018 - 22:00
The way research in quantum technology will be taken forward has been laid out in a revised roadmap for the field.Published today in the New Journal of Physics, leading European quantum researchers summarise the field's current status, and examine its challenges and goals.

Should all babies have their genomes sequenced?

EurekAlert! - Mar, 08/14/2018 - 22:00
New Hastings Center special report outlines ethics and policy recommendations on genome-wide sequencing of newborns.

New HIV therapy reduces virus, boosts immunity in drug-resistant patients

EurekAlert! - Mar, 08/14/2018 - 22:00
In a study, a new HIV drug reduced viral replication and increased immune cells in individuals with advanced, drug-resistant HIV infection. Used in combination with existing HIV medications, the drug is a promising strategy for patients who have run out of effective treatment options, the researchers said.

How many American cities protect the rights of employed breastfeeding mothers?

EurekAlert! - Mar, 08/14/2018 - 22:00
Research from the University of Pennsylvania School of Nursing and the Children's Hospital of Philadelphia found that, among the 151 largest cities in the United States, only Philadelphia and New York City have local legislation that protects a nursing mother who returns to work outside the home and who wants to continue breastfeeding.

Particles pull last drops of oil from well water

EurekAlert! - Mar, 08/14/2018 - 22:00
Rice University engineers develop magnetic nanoparticles that separate the last droplets of oil from produced water at wells.

PARP inhibitor improves progression-free survival in patients with advanced breast cancers

EurekAlert! - Mar, 08/14/2018 - 22:00
In a randomized, Phase III trial led by researchers at The University of Texas MD Anderson Cancer Center, the PARP inhibitor talazoparib extended progression-free survival (PFS) and improved quality-of-life measures over available chemotherapies for patients with metastatic HER2-negative breast cancer and mutations in the BRCA1/2 genes.

Study of material surrounding distant stars shows Earth's ingredients 'pretty normal'

EurekAlert! - Mar, 08/14/2018 - 22:00
The Earth's building blocks seem to be built from 'pretty normal' ingredients, according to researchers working with the world's most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere.

Weight gain after smoking cessation linked to increased short-term diabetes risk

EurekAlert! - Mar, 08/14/2018 - 22:00
People who gain weight after they quit smoking may face a temporary increase in the risk of developing type 2 diabetes, with the risk directly proportional to the weight gain.

Widespread declines in life expectancy across high income countries coincide with rising young adult and midlife mortality in the United States

EurekAlert! - Mar, 08/14/2018 - 22:00
The ongoing opioid epidemic in the United States is a key contributor to the most recent declines in life expectancy, suggests a study published by The BMJ today.

Old species learn new tricks...very slowly

EurekAlert! - Mar, 08/14/2018 - 22:00
No species lasts forever, and, just as the saying goes, it seems like old species may get stuck in their ways and can't adapt to environmental change as fast as younger species do.

Frequent fires make droughts harder for young trees, even in wet eastern forests

EurekAlert! - Mar, 08/14/2018 - 22:00
Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.

Diving robots find Antarctic seas exhale surprising amounts of carbon dioxide in winter

EurekAlert! - Mar, 08/14/2018 - 22:00
The open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide in winter than previously believed, a new study has found. Researchers conducting the study used data gathered over several winters by an array of robotic floats diving and drifting in the Southern Ocean around the southernmost continent.

Mechanism that affects multiplication of dengue virus lineage is discovered

EurekAlert! - Mar, 08/14/2018 - 22:00
A study aiming at the development of a dengue vaccine shows that the prevalence of a virus lineage upon the other does not rely on the highest replication rate: it is rather based on the virus' ability in triggering weaker activation of the patient's immune response.

New clues into how 'trash bag of the cell' traps and seals off waste

EurekAlert! - Mar, 08/14/2018 - 22:00
The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight into how this process seals off waste, much like a trash bag.

Evening preference, lack of sleep associated with higher BMI in people with prediabetes

EurekAlert! - Mar, 08/14/2018 - 22:00
People with prediabetes who go to bed later, eat meals later and are more active and alert later in the day -- those who have an 'evening preference' -- have higher body mass indices compared with people with prediabetes who do things earlier in the day, or exhibit morning preference.

Funny bone: ASU survey finds 99 percent of science students appreciate instructor humor

EurekAlert! - Mar, 08/14/2018 - 22:00
In a first-of-its-kind study published today in the journal PLOS ONE, researchers from Arizona State University found that students appreciate when instructors tell jokes in science class, but that female and male students differ in what topics they find funny or offensive.

Students' social skills flourish best in groups with similar skill levels

EurekAlert! - Mar, 08/14/2018 - 22:00
Researchers at the University of Missouri have found that children who need assistance improving their social skills might benefit more when grouped with peers who have similar social skill levels, rather than with peers who have a similar disability or disorder.

Battery breakthrough: Doubling performance with lithium metal that doesn't catch fire

EurekAlert! - Mar, 08/14/2018 - 22:00
A rechargeable battery technology developed at the University of Michigan could double the output of today's lithium ion cells -- drastically extending electric vehicle ranges and time between cell phone charges -- without taking up any added space.

This matrix delivers healing stem cells to injured elderly muscles

EurekAlert! - Mar, 08/14/2018 - 22:00
Muscles of the elderly and of patients with Duchene muscular dystrophy have trouble regenerating. A new nanohydrogel with muscle stem cells has boosted muscle growth in mouse models while protecting the stem cells from immune reactions that usually weaken or destroy them.
