Heating pads may lower blood pressure in people with high blood pressure when lying down
- ScienceDaily
- 19/9/6 23:25
In people with supine hypertension due to autonomic failure, a condition that increases blood pressure when lying down, overnight heat therapy significantly decreased systolic blood pressure compared to a placebo. Heat therapy may be an innovative, non-pharmacologic approach to treat the overnight high blood pressure in these patients.
Not all meat is created equal: How diet changes can sustain world's food production

An environmental engineer has created a model that predicts how several different conservation approaches could reduce demand for a nonrenewable resource that is absolutely vital for feeding the world: phosphorus.
A swifter way towards 3D-printed organs
- ScienceDaily
- 19/9/6 23:24
Twenty people die waiting for an organ transplant every day in the US, but lab-grown organs so far lack the cellular density, vasculature, and functions required to make them viable replacements. The new SWIFT method solves those problems by 3D printing vascular channel networks directly into living organ building blocks, enabling the creation of larger tissues approximating the size and function...

New research suggests that streamflow variability brought on by climate change will negatively affect the survival of salamanders.
Disrupting the gut microbiome may affect some immune responses to flu vaccination
- ScienceDaily
- 19/9/6 23:24
The normal human gut microbiome is a flourishing community of microorganisms, some of which can affect the human immune system. Researchers have now found that oral antibiotics, which can kill gut microorganisms, can alter the human immune response to seasonal influenza vaccination.
Key enzyme found in plants could guide development of medicines and other products
- ScienceDaily
- 19/9/6 19:40
Researchers studying how plants evolved the abilities to make natural chemicals, which they use to adapt to stress, have uncovered how an enzyme called chalcone isomerase evolved to enable plants to make products vital to their own survival. The researchers' hope is that this knowledge will inform the manufacture of products that are beneficial to humans, including medications and improved crops.

- ScienceDaily
- 19/9/6 19:40
While it's impossible to predict just where the next wildfire will start, new researc is getting into the microscopic details of how fires initiate to provide more insight into how wildfires burn through wildland fuels.
Rare deer likely lived 50 years beyond declaration of extinction
- ScienceDaily
- 19/9/6 19:40
Schomburgk's deer (Rucervus schomburgki) was added to the extinction list in 1938. But new evidence, gleaned from antlers obtained in late 1990 or early 1991, shows that it survived for at least an additional half century and might still be around today.
Sum of three cubes for 42 finally solved -- using real life planetary computer
- ScienceDaily
- 19/9/6 19:40
Hot on the heels of the ground-breaking 'Sum-Of-Three-Cubes' solution for the number 33, mathematicians have solved the final piece of the famous 65-year-old math puzzle with an answer for the most elusive number of all - 42.
Scientists couple magnetization to superconductivity for quantum discoveries
- ScienceDaily
- 19/9/6 19:40
In a recent study, scientists have created a miniaturized chip-based superconducting circuit that couples quantum waves of magnetic spins called magnons to photons of equivalent energy.
Teens who don't date are less depressed and have better social skills

Adolescents who were not in romantic relationships during middle and high school had good social skills and low depression, and fared better or equal to peers who dated.
Combating prison recidivism with plants
- ScienceDaily
- 19/9/6 19:40
The United States currently incarcerates the greatest percentage of its population compared with any other nation in the world. The results and information gathered in this study support the notion that horticultural activities can play an important role in influencing an offender's successful reentry into society.
Biomarker identified for early beta cell death in Type 1 diabetes
- ScienceDaily
- 19/9/6 19:40
Beta cells in the pancreas produce insulin. Their death is a key feature of Type 1 diabetes, and that loss starts long before diagnosis. However, there has been no straightforward way to measure that early loss. Researchers now have identified an early biomarker of Type 1 diabetes-associated beta-cell loss in humans -- microRNA-204. This biomarker may provide a much needed approach to assess early...
Pain in the asp: Bird-deterring nets create haven for stinging pests
- ScienceDaily
- 19/9/6 19:40
While collecting data from live oak trees in the world's largest medical center, evolutionary ecologists have discovered huge quantities of one of North America's most venomous caterpillars.
Why should you care about AI used for hiring?
- ScienceDaily
- 19/9/6 19:40
Researchers have explored the hype and mystique surrounding artificial intelligence in hiring. They provide an overview of artificial intelligence in the workplace, provides practical to-dos for organizations considering AI tools for their hiring process, and explains how psychologists can help along the way.
South African study highlights links between low language ability and poor mental health

A new study focuses on language acquisition for young people in Khayelitsha near Cape Town.
Science puts historical claims to the test
- ScienceDaily
- 19/9/6 16:41
Two studies show that today's analytical techniques are sufficiently advanced to differentiate between authentic historical artefacts and those that aren't quite what they seem.
Feeding pets raw food is not considered by pet owners as a significant source of infections
- ScienceDaily
- 19/9/6 16:41
An extensive international survey indicates that pet owners do not consider raw food to considerably increase infection risk in their household. In the survey, targeted at pet owners, raw food was reliably determined to be a contaminant only in three households.
Speech impairment in five-year-old international adoptees with cleft palate
- ScienceDaily
- 19/9/6 16:41
In a group of internationally adopted children with cleft lip and/or palate, speech at age five is impaired compared to a corresponding group of children born in Sweden, a study shows. The adopted children also need more extensive surgery, which may be due to their surgical interventions taking place later in life.

How our brain filters sounds
- ScienceDaily
- 19/9/6 15:27
When two identical sounds are repeated quickly, a filter reduces the attention that the brain directs to the second sound it hears. In people with schizophrenia, this ability to reduce the brain's response to identical sounds does not function properly. But the question is: Why? Neuroscientists have been investigating the mechanism that lies behind this auditory sensory gating. Their results show...
