Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations.
There are five general classes of hormones: auxins, cytokinins, gibberellins, ethylene
Plant hormones are signal molecules, present in trace quantities, that act as major regulators of plant growth and development. They are involved in a wide range of processes such as elongation, flowering, root formation and vascular differentiation. For many years, agriculturists have applied hormon...

Machine learning – Next new level of computer evolution
Machine learning is the subfield of computer science that, according to Arthur Samuel, gives "computers the ability to learn without being explicitly programmed
Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome.
There is little doubt that Machine Learning (ML) and Artif...

UNIVERSITY OF UTAH RESEARCHERS DEVELOP FASTER, MORE ACCURATE TEST FOR LIVER CANCER THAT CAN BE ADMINISTERED ANYWHERE
It’s estimated that about 788,000 people worldwide died of liver cancer in 2015, the second-leading cause of cancer deaths, according to the latest statistics from the World Health Organization. One of the major challenges in combatting this disease is detecting it early because symptoms often don’t appear until later stages.
But a team of researchers led by University of Utah chemical engineering and chemistry professor Marc Porter and U surgeon and professor Courtney Scaife has developed a ...

Yale University research suggest loss of arctic sea ice impacting atlantic ocean water circulation system
Arctic sea ice is not merely a passive responder to the climate changes occurring around the world, according to new research.
Scientists at Yale University and the University of Southampton say the ongoing Arctic ice loss can play an active role in altering one of the planet’s largest water circulation systems: the Atlantic Meridional Overturning Circulation (AMOC).
AMOC has a lower limb of dense, cold water that flows south from the north Atlantic, and an upper limb of warm, salty wa...

piezoelectric sensor is a device that uses the piezoelectric effect, to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge
A piezoelectric sensor is a device that uses the piezoelectric effect, to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press' or 'squeeze'.
A proper knowledge of the interaction between human physiology and daily living environmental conditions is essential to establish a connection between an individual’s lifestyle and his/her health status. Understanding these connections will give insight ...

High Dietary Energy Density (DED) foods may increase cancer risk regardless of obesity status
Dietary energy density (DED) is defined as the amount of available energy per unit of weight in the diet. It is generally expressed as kJ/g. Experimental studies in human subjects and a recent systematic review have shown that the consumption of high-energy-dense diets may lead to increased energy intake and weight gain, and evidence has been accumulating for an association between lower DED and better nutritional quality of the diet.
In Swedish children and teenagers, it was found that low-e...

Scientists at UT Southwestern Medical Center have developed a new technique using high-frequency alternating magnetic fields to heat artificial joints in the body
A short exposure to an alternating magnetic field might someday replace multiple surgeries and weeks of IV antibiotics as treatment for stubborn infections on artificial joints, new research suggests.
Researchers at UT Southwestern Medical Center have shown that high-frequency alternating magnetic fields – the same principle used in induction cooktops – can be used to destroy bacteria that are encased in a slimy “biofilm” growing on a metal surface. The biofilm is a collection of microorganis...

North Carolina State University Spheroid Stem Cell Production Sows Hope for IPF (Idiopathic Pulmonary Fibrosis)Treatment
In a small pilot study, researchers from North Carolina State University have demonstrated a rapid, simple way to generate large numbers of lung stem cells for use in disease treatment. This method of harvesting and growing a patient’s own lung stem cells shows promise in mice for treating idiopathic pulmonary fibrosis (IPF), and could one day provide human IPF sufferers with an effective, less invasive method of treatment for their disease.
Idiopathic pulmonary fibrosis (IPF) is a chronic ir...

soft wearable robotic suit promotes normal walking in stroke patients, opening new approaches to gait re-training and rehabilitation
Upright walking on two legs is a defining trait in humans, enabling them to move very efficiently throughout their environment. This can all change in the blink of an eye when a stroke occurs. In about 80% of patients post-stroke, it is typical that one limb loses its ability to function normally — a clinical phenomenon called hemiparesis. And even patients ...

VCU Massey Cancer Center Scientists targeted the gene CtBP with a drug known as HIPP (2-hydroxy-imino phenylpyruvic acid) and were able to reduce the development of pre-cancerous polyps by half for colon cancer
Preclinical experiments, researchers at VCU Massey Cancer Center have uncovered a new way in which colon cancer develops, as well as a potential “silver bullet” for preventing and treating it. The findings may extend to ovarian, breast, lung, prostate and potentially other cancers that depend on the same mechanism for growth.

Augusta University research suggest, age and obesity conspire to damage the tiny blood vessels that feed the heart, causing heart failure
Age and obesity appear to create a perfect storm that can reduce blood flow through the tiny blood vessels that directly feed our heart muscle and put us at risk for heart failure, scientists report.
They call it “aged fat” and scientists now have evidence that the inflammation created by both age and fat have an additive effect that can thicken the walls of our coronary microvasculature without any evidence of the classic atherosclerotic plaque that many of us associate with heart disease....

Stanford researchers develop a new soft, growing robot
Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble.

Patients whose emergency surgery is delayed are at higher risk of death
BACKGROUND: Delay of surgery for hip fracture is associated with increased risk of morbidity and mortality, but the effects of surgical delays on mortality and resource use in the context of other emergency surgeries is poorly described. Our objective was to measure the independent association between delay of emergency surgery and in-hospital mortality, length of stay and costs.
METHODS: We identified all adult patients who underwent emergency noncardiac surgery between January 2012 an...
