The advent of electric vehicles and the growing pressures to decarbonise the transportation sector means that oil is facing significant competition for the first time within its core source of demand.

This has led to considerable focus within the industry and amongst commentators on the prospects for peak oil demand — the recognition that the combined forces of improving efficiency and building pressure to reduce carbon emissions and improve urban air quality is likely to cause oil demand to stop increasing after over years of almost uninterrupted growth. At the same time, the supply side of the oil market is experiencing its own revolution.

The advent of US tight oil has fundamentally altered the behaviour of oil markets, introducing a new and flexible source of competitive oil.

Hypertension – or high blood pressure – affects millions of Americans. Endocrine hypertension is a subset of hypertension caused by hormone imbalance, most frequently involving the pituitary or adrenal gland. Patients who develop hypertension before the age of 30 who have a strong family history of hypertension, adrenal tumors, or develop a low potassium level hypokalemia should be screened for endocrine hypertension.

Patients who have poor blood pressure control despite taking three or more blood pressure medications resistant hypertension should also be screened. Endocrine hypertension can be caused when glands produce too much or not enough hormone, or when they are affected by tumors. The most common form of endocrine hypertension, primary aldosteronism affects an estimated 5 percent to 10 percent of all patients with hypertension and is often under diagnosed.

Excessive aldosterone production by the adrenal glands leads to fluid retention, loss of potassium and hypertension. If untreated, hyperaldosteronism may cause an enlarged heart. Primary aldosteronism is diagnosed through blood and urine tests, and a CT scan of the adrenal glands.

Blood pressure is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body. Blood pressure normally rises and falls throughout the day, but it can damage your heart and cause health problems if it stays high for a long time. Hypertension, also called high blood pressure, is blood pressure that is higher than normal. Uncontrolled high blood pressure is common; however, certain groups of people are more likely to have control over their high blood pressure than others.

High blood pressure is more common in some areas of the United States than in others. However, this map likely underreports the true effect of hypertension in each state, because about 1 in 5 adults with high blood pressure is unaware of it and would not report having it.

Creating visual art is one of the defining characteristics of the human species, but the paucity of archaeological evidence means that we have limited information on the origin and evolution of this aspect of human culture. The components of art include colour, pattern and the reproduction of visual likeness. The 2D and 3D art forms that were created by Upper Palaeolithic Europeans at least 30 years ago are conceptually equivalent to those created in recent centuries, indicating that human cognition and symbolling activity, as well as anatomy, were fully modern by that time.

The origins of art are therefore much more ancient and lie within Africa, before worldwide human dispersal. Zig-zag and criss-cross patterns, nested curves and parallel lines are the earliest known patterns to have been created separately from the body; their similarity to entopic phenomena involuntary products of the visual system suggests a physiological origin. Analysis of early tool-making techniques suggests that creating 3D objects sculptures and reliefs involves their cognitive deconstruction into a series of surfaces, a principle that could have been applied to early sculpture.

The cognitive ability to create art separate from the body must have originated in Africa but the practice may have begun at different times in genetically and culturally distinct groups both within Africa and during global dispersal, leading to the regional variety seen in both ancient and recent art. At all stages in the evolution of artistic creativity, stylistic change must have been due to rare, highly gifted individuals.

Art, in its many forms, is practised by almost all human cultures and can be regarded as one of the defining characteristics of the human species. In all societies today, the visual arts are intimately intertwined with music, dance, ritual marking life landmarks, death, religion and politics and language poetry, song and story-telling.

Vocalization, ritualized movement and visual display are part of animal courtship and dominance competition as well as human ritual and communication, so it is likely that the roots of music, dance and body decoration lie deep in the evolutionary history of the animal kingdom. Nevertheless, with the evolution of human cognition, they were deployed in new ways, with complex symbolic meaning becoming attached to them.
