The medium shapes the message: New communication technologies may bias historical record

Wednesday February 20th, 2019 07:50:35 PM
The introduction of communication technologies appears to bias historical records in the direction of the content best suited for each technology, according to a new study.

Zebra stripes are not good landing strips

Wednesday February 20th, 2019 07:50:32 PM
The stripes of a zebra deter horse flies from landing on them, according to a new study.

Peer support, healing hands may curb prescription opioid misuse

Wednesday February 20th, 2019 06:36:29 PM
A program offering group support, acupuncture, mindfulness, massage and gentle exercise may help prevent patients on prescription opioids from spiraling down to drug misuse, overdose and death, according to a new study.

Establishing the molecular blueprint of early embryo development

Wednesday February 20th, 2019 06:36:23 PM
A team of biologists, physicists and mathematical modellers have studied the genetic activity of over 100,000 embryonic cells to establish the molecular blueprint of mouse early embryo development. This new research provides fundamentally important information on how mammalian embryos develop during gastrulation, a key stage of development, and paves the way for new understanding of the earliest stages of life.

Correlated nucleons may solve 35-year-old mystery

Wednesday February 20th, 2019 06:36:21 PM
A careful re-analysis of data taken as revealed a possible link between correlated protons and neutrons in the nucleus and a 35-year-old mystery. The data have led to the extraction of a universal function that describes the EMC Effect, the once-shocking discovery that quarks inside nuclei have lower average momenta than predicted, and supports an explanation for the effect.

Massive database traces mammal organ development, cell by single cell

Wednesday February 20th, 2019 06:36:13 PM
A new study has traced an important period of organ formation, cell by cell, in the developing mouse. The study is by far the largest dataset of its kind to date.

Scientists identify genetic mechanism involved in how females inherit traits

Wednesday February 20th, 2019 06:36:10 PM
Female cells randomly and permanently shut off one of the X chromosomes during embryonic development through a process called X chromosome inactivation, or XCI. Just how XCI occurs has remained unclear -- until now. New research performed on mouse female embryonic stem cells traces the origin of XCI to an RNA splicing mechanism.

Bat influenza viruses could infect humans

Wednesday February 20th, 2019 06:35:34 PM
Bats don't only carry the deadly Ebola virus, but are also a reservoir for a new type of influenza virus. These newly discovered flu viruses could potentially also attack the cells of humans and livestock, researchers have now shown.

Nitisinone increases melanin in people with albinism

Wednesday February 20th, 2019 05:19:38 PM
A small pilot clinical study suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision. Increased melanin could help protect people with the condition against the sun's UV rays and promote the development of normal vision.

Fossil fuel combustion is the main contributor to black carbon around Arctic

Wednesday February 20th, 2019 05:19:35 PM
Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a new study.

Ingredients for water could be made on surface of moon, a chemical factory

Wednesday February 20th, 2019 05:19:32 PM
When a stream of charged particles known as the solar wind careens onto the moon's surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich the moon's surface in ingredients that could make water, scientists have found.

Genetic clues to high rates of asthma in those of African ancestry

Wednesday February 20th, 2019 05:19:29 PM
In the largest study of its kind, researchers have found new clues into the parts of the human genome associated with the higher rates of asthma in those of African ancestry.

Vigorous exercise, fasting, hormones improve elimination of toxic, misfolded, unnecessary proteins in mouse and human cells

Wednesday February 20th, 2019 05:19:26 PM
A new study shows vigorous exercise and fasting improve the ability of human and mouse cells to remove misfolded, toxic, unnecessary proteins. The findings reveal a previously unknown mechanism that activates the cells' protein-disposal machinery, allowing them to adapt their protein content to shifting demands and new conditions.

Viruses that linger in gut could trigger type 1 diabetes

Wednesday February 20th, 2019 04:37:54 PM
Researchers provide new evidence supporting an association between elevated levels of enteroviruses in the intestinal tracts of children and islet autoimmunity, a precursor to type 1 diabetes.

A volcanic binge and its frosty hangover

Wednesday February 20th, 2019 04:22:40 PM
A major volcanic event could have triggered one of the largest glaciations in Earth's history -- the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers have discovered remnants of such a large igneous province that resulted from vast lava flows.

New therapeutic approach to combat African sleeping sickness

Wednesday February 20th, 2019 04:22:37 PM
Scientists working in a range of disciplines joined forces to identify a new approach to combat African sleeping sickness. Fundamental research has revealed a promising strategy to develop a suitable agent.

Earth may be 140 years away from reaching carbon levels not seen in 56 million years

Wednesday February 20th, 2019 04:22:21 PM
Total human carbon dioxide emissions could match those of Earth's last major greenhouse warming event in fewer than five generations, new research finds. A new study finds humans are pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum (PETM), a global warming event that occurred roughly 56 million years ago.

Yea, team! Winning fans see self-esteem boost

Wednesday February 20th, 2019 04:22:13 PM
Fans of a college football team that wins a big game could experience a boost in self-esteem that lasts at least two days after the event, a new study suggests.

The 'blue' in blueberries can help lower blood pressure

Wednesday February 20th, 2019 04:22:11 PM
A new study has found that eating 200g of blueberries every day for a month can lead to an improvement in blood vessel function and a decrease in systolic blood pressure in healthy people.

Can a nerve injury trigger ALS?

Wednesday February 20th, 2019 04:22:08 PM
Researchers have demonstrated that a peripheral nerve injury can trigger the onset and spread of the disease in an animal model of ALS.
