So far, the only direct evidence we have for the existence of dark matter is through gravity-based effects on the matter we can see.
And these gravitational effects are so pronounced that we know it must make up about 85 percent of all matter in…

Holographic cosmological model and thermodynamics on the horizon of the universe
The expansion of the Universe has occupied the minds of astronomers and astrophysicists for decades.
Among the cosmological models that have been suggested over the years, Lambda cold dark matter (LCDM) models are the simplest models that can…

New material developed could help clean energy revolution
Fuel cells and water electrolyzers that are cheap and efficient will form the cornerstone of a hydrogen fuel based economy, which is one of the most promising clean and sustainable alternatives to fossil fuels.
These devices rely on materials…

BU astrophysicist and collaborators reveal a new model of our heliosphere
The heliosphere is a vast region, extending more than twice as far as Pluto. It casts a magnetic “force field” around all the planets, deflecting charged particles that would otherwise muscle into the solar system and even tear through…

Ocean changes almost starved life of oxygen 800 million years ago
Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.
Then, as now, the planet had an “oxidizing” atmosphere, driven by…

Hydrogen energy at the root of life
Since the discovery of submarine hydrothermal vents around 40 years ago, these natural chemical reactors have been a focus for evolutionary researchers searching for the origin of life.
The vents emit hot water containing minerals, including…

CRISPR Immune Cells Not Only Survive, They Thrive After Infusion Into Cancer Patients
In the first-ever (sanctioned) investigational use of multiple edits to the human genome, a study found that cells edited in three specific ways and then removed from patients and brought back into the lab setting were able to kill cancer months…

Fireflies Face Extinction Threat Due To Pesticides, Habitat Loss, And Light Pollution
The International Union for the Conservation of Nature, a coalition of activist groups which recently charged that climate change is contributing to exploitation of women, is now arguing that various factors are causing 2,000 species of…

What is an electron? | ScienceBlogs
As surprising as it may sound, no one really knows what an electron is, and it is this fundamental question that has been the driving force for much of modern physics and eventually led to the development of quantum field theory.
To answer the…
