Continued concerns about global warming have boosted work on alternative fuel sources that reduce emissions. Hydrogen is an appealing, clean-burning fuel. Currently, most hydrogen comes from the processing of fossil fuels, which produces carbon dioxide as a byproduct. However, the electrolysis of water produces hydrogen without the release of greenhouse gases—provided the electricity used in the process comes from renewable energy.
The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.
Parts of your brain continue to function when you’re sleeping, researchers at Ecole Normale Supérieure in Paris and the University of Cambridge have discovered.
They recorded the EEG (brain waves) of human participants while they were awake after they were instructed to classify spoken words as either animals or objects by pressing a button, using the right hand for animals and the left hand for objects.
The space shuttle Enterprise has been ensconced aboard the USS Intrepid for just over two years. It sits in a silent warehouse, dramatically lit so it appears to be cruising in a dark vacuum. Tourists can wander around or under it at the exhibit; they can even walk up some stairs and get nose-to-nose with the Enterprise, staring down its long axis through a thick layer of glass. While the whole thing evokes space exploration, the Enterprise has never actually made it out of Earth's atmosphere.
A woman has reached the age of 24 without anyone realising she was missing a large part of her brain. The case highlights just how adaptable the organ is.
The discovery was made when the woman was admitted to the Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province complaining of dizziness and nausea. She told doctors she'd had problems walking steadily for most of her life, and her mother reported that she hadn't walked until she was 7 and that her speech only became intelligible at the age of 6.
Scientists may have developed an effective vaccine for the Ebola virus after an experimental immunisation gave monkeys long-term protection from the deadly disease.
Human trials for the experimental jab are underway at the National Institutes of Health in the United States, raising the prospect that the vaccine can be used to help resolve the current Ebola crisis in West Africa.
NIH’s monkey studies show that a single dose of the vaccine can trigger fast protection, but the effect waned unless the animals got a booster shot made a different way, according to research pu
University of Bristol researchers have discovered how to stop cells from attacking healthy body tissue in debilitating autoimmune diseases (such as multiple sclerosis), where the body’s immune system destroys its own tissue by mistake.
The cells were converted from being aggressive to actually protecting against disease.
Jack the Ripper, the scourge of Whitechapel and possibly the world's most famous cold case, has reportedly been solved by a businessman and a forensic analyst, according to The Daily Mail.
The partner teamed up after businessman Russell Edwards obtained a shawl that supposedly belonged to Catherine Eddowes, an unfortunate victim to the Ripper's grisly murders. Enlisting forensic expert Jari Louhelainen's expertise, particularly with historic murders, the evidence shows "beyond a reasonable doubt," which one of the six potential suspects Jack the Ripper actually was.
Though galaxies look larger than atoms and elephants appear to outweigh ants, some physicists have begun to suspect that size differences are illusory. Perhaps the fundamental description of the universe does not include the concepts of “mass” and “length,” implying that at its core, nature lacks a sense of scale.
An experiment of taking samples from illuminators and the ISS surface has brought unique results, as scientists had found traces of sea plankton there, the chief of an orbital mission on Russia’s ISS segment told reporters.
