A research team has sequenced the genome of a 45,000-year-old modern human male from western Siberia. The comparison of his genome to the genomes of people that lived later in Europe and Asia show that he lived close in time to when the ancestors of present-day people in Europe and eastern Asia went different ways.
New population projections provide a fundamentally improved view of future population, structured by age, sex and level of education, which differ from recent projections by the UN. World population will likely peak at 9.4 billion around 2070 and then decline to around 9 billion by 2100, according to the new projections.
Pay attention to the implication of these new research results: people who pay more attention to their feelings and experiences tend to have better cardiovascular health.
The Dallas hospital where a man diagnosed with Ebola died and two nurses were infected with the virus has seen patients flee the hospital, with a more than 50 percent decline in visits to its emergency room since the crisis began.
Football teams are claiming a special ingredient improves their athletic performance and, according to new research, it also benefits heart failure patients. The special ingredient: beetroot.
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. Now, this achievement has been realized on the microscale.
At first glance, the static, greyscale display created by a group of researchers might not catch the eye of a thoughtful consumer in a market saturated with flashy, colorful electronics. But a closer look at the specs could change that: the ultra-thin LCD screen is capable of holding three-dimensional images without a power source, making it a compact, energy-efficient way to display visual information.
Relatively little work has been done on feather morphology, especially from a mechanical perspective and never at the nanoscale. Now, scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight.
Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go. New research explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built.
Being unsteady on our feet is something we can experience throughout life– and a new study has shown how even the lightest fingertip touch can help people to maintain their balance. The research explains how neural and mechanical mechanisms synchronize our sway with another person.
Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. Now, researchers have developed a new way to model the effects of these genetic mutations in mice.
Researchers have found a definitive link between gait– the way someone walks– and early changes in cognitive function in people with Parkinson's disease. And the find could mean that gait may be used as an early warning sign to help predict the development of cognitive impairment and dementia in Parkinson’s.
So long, Silicon Valley. These days entrepreneurs and engineers are flocking to a place better known for wave surfing than Web surfing. Amid the palm trees and purple sunsets of the Southern California coastline, techies have built "Silicon Beach."
Justin Yeakel and a team used depictions of animals in ancient Egyptian artifacts to assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years.
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could, one day, replace the syringe.
Tetsuya Theodore Fujita, born Oct. 23, 1920, was a Japanese-American meteorologist who increased the knowledge of severe storms. He was known as "Mr. Tornado" as a result of the Fujita scale, which he and his wife, Sumiko, developed for measuring tornadoes on the basis of their damage.
