Culture
Did you know that music and diagnostic imaging have something in common? Sounds have a lower or higher pitch depending on the size of the object that creates them. Tubas and double basses are big and produce deep low-pitch sounds, while flutes and violins are small and produce high-pitched sounds. What's interesting is that the same effect occurs when biological structures like cells or tissues emit sound - the pitch varies with size.
But what kind of sounds do biological structures make? Moreover, how can we listen to them?
CHAMPAIGN, Ill. -- A new study in mice suggests that consuming the chemical compounds found in thermally abused cooking oil may trigger genetic changes that promote the progression of late-stage breast cancer.
Thermally abused frying oil - cooking oil that has been repeatedly reheated to high temperatures - may act as a toxicological trigger that promotes tumor cell proliferation, metastases and changes in lipid metabolism, scientists at the University of Illinois found. They reported their findings in the journal Cancer Prevention Research.
Adopting stricter state gun laws is linked to a safer school experience for students, finds research published in the Journal of Epidemiology & Community Health.
Strengthening gun laws at state level was associated with teens being less likely to report being threatened or injured with a weapon at school, miss at least one day of school due to feeling unsafe, or to carry a weapon at any location.
New research suggests that targeted use of behavioural 'nudges' can encourage people to conserve water.
Researchers at the University of East Anglia (UEA) found that rather than giving people general information about the importance of saving water, emphasising the water conserving actions of others in the same social group - for example university students or local residents - encourages similar behaviour changes and reduces water demand.
FINDINGS
A study has found that out-of-pocket health care spending and medical debt are substantially higher when adults have a history of adverse childhood experiences. The study showed that household medical costs were 30 percent higher, and the likelihood of medical debt was doubled, when an adult had lived through three or more adverse experiences during childhood.
BACKGROUND
An international team of researchers has built a new sensor network that can monitor two crucial activities, namely biodiversity, or the variety of life, in a particular habitat or ecosystem, and identification of possible illegal activities such as logging or poaching in protected areas. This wireless recording network is capable of recording an ecosystem's sounds with the same quality as devices that have been used to date, but it is significantly more energy-efficient and cost-effective.
PITTSBURGH, March 21, 2019 - Social media has given those espousing anti-vaccination sentiments an effective medium to spread their message. However, an analysis of a viral Facebook campaign against a Pittsburgh pediatric practice reveals that the movement isn't "all about autism." Instead, the research from the University of Pittsburgh Center for Research on Media, Technology, and Health finds that anti-vaccination arguments center on four distinct themes that can appeal to diverse audiences.
Seychelles warblers live and breed in family groups on the tiny island of Cousin. In each group, a dominant female and male reproduce. When helpers assist the with incubation and feeding of chicks, the dominant female breeders age more slowly and live longer, a study by biologists from the University of Groningen and colleagues from the Universities of East Anglia, Leeds, Sheffield, and Wageningen shows.
Each year, approximately 265,000 Americans have a stroke that causes visual impairment. New research, which appears in the journal Proceedings of the Royal Society B, sheds light on how the damage in the brain caused by a stroke can lead to permanent vision impairment. The findings could provide researchers with a blueprint to better identify which areas of vision are recoverable, facilitating the development of more effective interventions to encourage vision recovery.
The center of our galaxy is a frenzy of activity. A behemoth black hole -- 4 million times as massive as the sun -- blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently explode.
Now, an international team of astronomers has discovered two exhaust channels -- dubbed "galactic center chimneys" -- that appear to funnel matter and energy away from the cosmic fireworks in the Milky Way's center, about 28,000 light-years from Earth.
MINNEAPOLIS - Some studies have suggested that people who are younger when they enter puberty are more likely to later develop multiple sclerosis (MS). But a new study attributes that link to body mass index (BMI). The study is published in the March 20, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Irvine, Calif., March 20, 2019 - Here's something to chew on: One in four people are impacted by defects of the temporomandibular - or jaw - joint. Despite the pervasiveness of this affliction, treatments are lacking, and many sufferers resort to palliative measures to cope with the pain and debilitation it causes.
The prognosis for older patients with acute myeloid leukemia (AML) is poor: very few achieve remission and for those that don't the option is largely palliative.
Every year almost 1000 Australians die of the disease and clinical trials into new therapies for older patients have largely failed.
A new Australian drug trial has achieved a remarkable result, clearing the bone marrow of leukaemia in almost 60% of patients.
The trial was considered so effective that the US Food and Drug Administration approved its use last November for the treatment of AML.
A new study published in Infant and Child Development indicates that complications during birth may increase the risk that children will develop social anxiety by their pre-teen years.
March 20, 2019 - Salads were recently in the news--and off America's dinner tables--when romaine lettuce was recalled nationwide. Outbreaks of intestinal illness were traced to romaine lettuce contaminated with Escherichia coli (E. coli) bacteria.
These bacteria occur naturally in the intestines of warm-blooded animals. Because crops are grown in the natural environment, E.coli may get into the fields, contaminating produce. The results are potentially deadly for people who eat that produce.
