Cities affect temperatures for thousands of miles
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. In a new study that shows the extent to which human activities are influencing the atmosphere, scientists ...
Physicists Investigate Possibility of an 'Unhiggs'
Vegetation can help prevent soil erosion due to wind
Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate.
New 31-km-long International Linear Collider ready for construction
Today the Linear Collider Collaboration published its Technical Design Report [PDF] for the International Linear Collider (ILC) - a proposed 31-kilometer electron-positron collider that will both complement and advance beyond the physics of the Large Had ...
Model shows wind could meet many times world's total power demand by 2030
In 2030, if all energy is converted to clean energy, humans will consume about eleven-and-a-half terawatts of power every year, all sources combined. If there is to be a clean-energy economy based on renewable ...
Researchers use real data rather than theory to measure the cosmos
For the first time researchers have measured large distances in the Universe using data, rather than calculations related to general relativity.
Innovative 3-D designs can more than double solar power generated from a given area
(PhysOrg.com) -- Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways ...
Berkeley Lab scientists identify new driver behind Arctic warming
Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice.
Model describes universe with no big bang, no beginning, and no end
Most distant blazar is a high-energy astrophysics puzzle
(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source ...
Can R2 gravity explain dark matter?
Dark matter mystery deepens
(PhysOrg.com) -- Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter ...
New Data Suggests We Don’t Live in a Void, and Supports Dark Energy
Gas rich galaxies confirm prediction of modified gravity theory
(PhysOrg.com) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. ...
