Scientists have shown that, in ancient times, the Earth’s magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in [...]

Converting the rubbish that fills the world’s landfills into biofuel may be the answer to both the growing energy crisis and to tackling carbon emissions, claim scientists in Singapore and Switzerland. New research reveals how replacing gasoline with biofuel from processed waste could cut global carbon emissions by 80%.

A daily supplement of vitamin D at a dose of 700-1000 IU reduces the risk of falling among older people by 19 percent according to a new study. But a dose of less than 700 IU per day has no effect.

The human brain has evolved over millions of years to become a vast network of billions of neurons and synaptic connections. Understanding it is one of humankind’s greatest pursuits. But to understand how the brain processes information, researchers must first understand the very basics of neurons — even down to how proteins inside the neurons [...]
New research looks at the specific ways parents and peers influence teenagers to smoke, drink and use marijuana in combination.
Researchers have done the most detailed analysis ever of a layer of sediments deposited during and immediately after the asteroid impact 65 million years ago that wiped out the dinosaurs and 80 percent of Earth’s marine life. They found that at least some forms of microscopic marine life — the so-called “primary producers,” or photosynthetic [...]

Repeated learning sessions produce long-lasting memory when they are spaced out between rest intervals. Neuroscientists have discovered that this so-called “spacing effect” is controlled in the brain by a molecular timer — a protein that determines how long rest intervals need to last for long-term memory to form.
A new study resolves a 130-year-old mystery over the developmental origin of specialized skin cells involved in touch sensation.

Preterm infants who receive leg movement training display feet-reaching behaviors similar to that of full-term infants, according to a randomized controlled trial. This finding supports feet-reaching play as an early intervention strategy to encourage interaction with physical objects in preterm infants who have movement problems within the first months of postnatal life.
