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.
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.
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.
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.
India's Mission Control lost contact with the lander for its Chandrayaan 2 mission today, just as it was about to make a touchdown near the moon's south pole. Chandrayaan 2's Vikram lander descended to a highland plain between two craters, Manzinus C and Simpelius N, at a latitude of 70.9 degrees south. But contact was lost in the final moments of the descent. During the minutes that...

For tens of millions of people, migration is a tough reality. What causes people to migrate away from their home countries, and what happens when they do? Migrants and their labor are responsible for moving hundreds of billions of dollars around the world annually. At their destinations, they affect populations, cultures, and economies. But their movement also has a major impact on the places they...
India aims to become the first country to make a soft landing on the Moon's south pole.

First discovered in 1947 by Bedouin shepherds looking for a lost sheep, the ancient Hebrew texts known as the Dead Sea Scrolls are some of the most well-preserved ancient written materials ever found. Now, a study by researchers at MIT and elsewhere elucidates a unique ancient technology of parchment making and provides potentially new insights into methods to better preserve these precious...
Tomasz Szauksztel was near the summit of Alberta’s Caldron Peak mountain when the air around him began to...
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.
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.
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.
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.
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.
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.
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.
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...
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.
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.
A weakened Hurricane Dorian flooded homes on North Carolina's Outer Banks on Friday with a ferocity that took even storm-hardened residents by surprise, forcing people to retreat to their attics. Hundreds were feared trapped by high water.
France's agriculture ministry said Friday that it had detected its first cases of a bacterium that has been devastating olive trees in Italy and elsewhere in the Mediterranean basin.
Oil and gas projects approved by major fossil fuel companies over the last 20 months threaten both shareholder value and efforts to keep Earth from overheating, according to an analysis released Friday.
If you wanted to really mess with the world's food production, a good place to start would be in Morocco. They don't grow much here, but it is home to mines containing most of the world's known reserves of phosphate rock, the main source of the nutrient phosphorus. Most of us across the globe, most days, will eat some food grown on fields fertilized by phosphate rock from these mines.
Plants can do many amazing things. Among their talents, they can manufacture compounds that help them repel pests, attract pollinators, cure infections and protect themselves from excess temperatures, drought and other hazards in the environment.

How do stars and planets form? Scientists are now one step closer to pinning down the conditions for the formation of proto-stellar disks. Observations of three systems in the early stages of star formation in the Perseus cloud revealed that the profile of the angular momentum in these systems is between that expected for a solid body and pure turbulence, indicating that the influence of the core...

In the course of conducting this research, the team successfully overcame two...
Lithium-sulphur batteries are regarded as one of the most promising candidates for the next generation of energy storage devices. They have a theoretical gravimetric energy density that is five times higher than that of the best lithium-ion batteries currently available. And they even work at sub-zero temperatures of down to -50 °C. In addition, sulphur is inexpensive and environmentally...
