| WHO issues roadmap to scale up international response to the Ebola outbreak in west Africa Posted: 29 Aug 2014 08:54 AM PDT The World Health Organization has issued a roadmap to guide and coordinate the international response to the outbreak of Ebola virus disease in west Africa. The aim is to stop ongoing Ebola transmission worldwide within 6-9 months, while rapidly managing the consequences of any further international spread. |
| How nerve cells communicate with each other over long distances: Travelling by resonance Posted: 29 Aug 2014 05:38 AM PDT How nerve cells within the brain communicate with each other over long distances has puzzled scientists for decades. The way networks of neurons connect and how individual cells react to incoming pulses in principle makes communication over large distances impossible. Scientists provide now a possible answer how the brain can function nonetheless: by exploiting the powers of resonance. |
| The universal 'anger face': Each element makes you look physically stronger and more formidable Posted: 28 Aug 2014 03:48 PM PDT The next time you get really mad, take a look in the mirror. See the lowered brow, the thinned lips and the flared nostrils? That's what social scientists call the "anger face," and it appears to be part of our basic biology as humans. Now, researchers have identified the functional advantages that caused the specific appearance of the anger face to evolve. |
| Second-hand e-cig smoke compared to regular cigarette smoke Posted: 28 Aug 2014 11:28 AM PDT Second-hand e-cig smoke has 10 times less particulate matter than regular cigarette smoke; but higher levels of certain toxic metals, a new study finds. |
| Home is where the microbes are Posted: 28 Aug 2014 11:27 AM PDT A person's home is their castle, and they populate it with their own subjects: millions and millions of bacteria. Scientists have detailed the microbes that live in houses and apartments. The results shed light on the complicated interaction between humans and the microbes that live on and around us. Mounting evidence suggests that these microscopic, teeming communities play a role in human health and disease treatment and transmission. |
| Posted: 28 Aug 2014 11:27 AM PDT Stimulating a region in the brain via non-invasive delivery of electrical current using magnetic pulses, called Transcranial Magnetic Stimulation, improves memory. The discovery opens a new field of possibilities for treating memory impairments caused by conditions such as stroke, early-stage Alzheimer's disease, traumatic brain injury, cardiac arrest and the memory problems that occur in healthy aging. |
| Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak Posted: 28 Aug 2014 11:27 AM PDT In response to an ongoing, unprecedented outbreak of Ebola virus disease in West Africa, a team of researchers has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. |
| From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells Posted: 28 Aug 2014 11:27 AM PDT Rabies is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. A new article sheds light on how the virus hijacks the transport system in nerve cells to reach the brain with maximal speed and efficiency. |
| Posted: 28 Aug 2014 10:58 AM PDT Biochemists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines. Their hope now would be to see whether it is possible to manipulate this switch to make nature's antibiotic factory more efficient. |
| Computer games give a boost to English Posted: 28 Aug 2014 10:53 AM PDT If you want to make a mark in the world of computer games you had better have a good English vocabulary. It has now also been scientifically demonstrated that someone who is good at computer games has a larger English vocabulary. |
| Study reveals drivers of Western consumers' readiness to eat insects Posted: 28 Aug 2014 08:52 AM PDT The most likely early adopters of insets as a meat substitute in Western societies are young men with weak attitudes toward meat, who are open to trying novel foods and interested in the environmental impact of their food choice. With a low level of food neophobia, the likelihood that this type of person is willing to eat insects as a meat substitute is estimated more than 75%, according to a new study. |
| Protein glue shows potential for use with biomaterials Posted: 27 Aug 2014 06:37 PM PDT Scientists have shown that a synthetic protein called AGMA1 has the potential to promote the adhesion of brain cells in a laboratory setting. It is also cheaper and easier to produce on a large scale. This could help overcome a major challenge in nerve tissue engineering. |
