Determining levels of consciousness in people who have severe brain injury is notoriously hard. That task may become a little easier with the finding that brain scans can help doctors identify whether patients in a vegetative or minimally conscious state are likely to recover to some degree.
Clare Blackburn of Edinburgh University in Britain, and her colleagues have treated, in mice, an organ called the thymus, a part of the immune system that runs down in old age. Instead of adding stem cells they have stimulated their animals’ thymuses to make more of a protein known as FOXN1. This is a transcription factor (a molecular switch that activates genes), and for the thymus it turns out to be an elixir of life.
Animals are exceptionally complicated things. So complicated, in fact, that we've never actually built one ourselves. But the day is fast approaching when we'll be able to create digital versions of organisms on a computer — from the way they move right through to their behaviors. Here's how we'll do it.
Not content with perhaps the biggest scientific discovery of the decade, scientists at the Large Hadron Collide continue to search for new particles -- and now they've found one that seems to be an entirely new form of matter.
To celebrate National Library Week in the United States (April 13th-19th) and all the hard work librarians do to support their patrons, OUP is freeing up all of its online resources (excluding journals) for the week.
The potential moon (nicknamed Peggy) is tiny, probably only about a kilometer (0.6 miles) across — really a moonlet — and is invisible in the Cassini pictures. However, its presence is betrayed by an odd clumping of material at the very edge of Saturn’s A ring, the outermost of Saturn’s main rings.
A team of Chinese scientists did an impossible-sounding thing. They created electricity simply by dragging a droplet of saltwater across a layer of graphene. No big fires, no greenhouse gases, no fuss. They created energy with just a miracle material and one of the most plentiful substances on Earth.
By recreating the setting from Aesop's Fable 'The crow and the pitcher', researchers have shown that corvids are not just capable of grasping that solid objects displace water, but more crucially, they seem to understand the causal relationship between the properties of such objects and their effectiveness.
A PBS series aims to show how humans evolved from creatures of the deep. But creationists have denounced it as an attempt to ‘package unconditional blind faith in evolution as scientific literacy in an effort to create interest in science'.
The major parties are also touting policies on nuclear power, the internet, climate change and genetically engineered crops. Our guide explores the science and technology that feature in this Indian election.
Different bird sounds have different functions. Songbirds use elaborate music to attract a mate or to let rivals know the limits of their territory; other kinds of birds will chirp for food or to communicate a message to their peers, such as the presence of a predator. But there are other factors that determine why songs and calls may not sound so much alike from one species to the next.
