A first cell atlas of the human thymus gland could lead to new immune therapies to treat cancer and autoimmune diseases. Researchers mapped thymus tissue through the human lifespan to understand how it develops and makes vital immune cells called T cells. In t…

Earth formed much faster than previously thought, new study shows

more than 30 days ago

By measuring iron isotopes, researchers have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

Old carbon reservoirs unlikely to cause massive greenhouse gas release, study finds

more than 30 days ago

As global temperatures rise, permafrost and methane hydrates -- large reservoirs of ancient carbon -- have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. But would this methane actually reach the atmosphere? Re…

Earthquakes disrupt sperm whales' ability to find food

more than 30 days ago

Scientists studying sperm whales have discovered earthquakes affect their ability to find food for at least a year. The research is among the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how t…

Earliest interbreeding event between ancient human populations discovered

more than 30 days ago

A new study documented the earliest known interbreeding event between ancient human populations -- a group known as the 'super-archaics' in Eurasia interbred with a Neanderthal-Denisovan ancestor about 700,000 years ago. The event was between two populations m…

How newborn stars prepare for the birth of planets

more than 30 days ago

Astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earli…

Bumble bees can experience an object using one sense and later recognize it using another

more than 30 days ago

The ability to recognize objects across different senses is present in the tiny brains of an insect, researchers have discovered.

Methane emitted by humans vastly underestimated

more than 30 days ago

Researchers measured methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels. The researchers indicate that reducing fossil fuel use is a ke…
