Think chimpanzee beds are dirtier than human ones? Think again Posted: 16 May 2018 02:23 PM PDT Chimpanzees (Pan troglodytes) appear to keep tidier sleeping arrangements than humans do. That's one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night. |
The mystery of lime-green lizard blood Posted: 16 May 2018 02:23 PM PDT Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards remain healthy with levels of green bile that are 40 times higher than the lethal concentration in humans. |
Alternative treatment for mild asthma Posted: 16 May 2018 02:23 PM PDT People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option. |

Cannabidiol significantly reduces seizures in patients with severe form of epilepsy Posted: 16 May 2018 02:22 PM PDT Cannabidiol (CBD), a compound derived from the cannabis plant that does not produce a 'high,' was shown in a new large-scale, randomized, controlled trial to significantly reduce the number of dangerous seizures in patients with a severe form of epilepsy called Lennox-Gastaut syndrome. This study also is the first to offer information on cannabidiol dosing for patients with treatment-resistant epilepsy. |
Novel therapy inhibits complement to preserve neurons and reduce inflammation after stroke Posted: 16 May 2018 11:46 AM PDT Researchers report that, after ischemic stroke, the complement system identifies stressed but salvageable neurons for removal by microglial phagocytosis. To preserve these neurons, the investigators designed a novel therapeutic that targets a complement inhibitor to a damage signal expressed after stroke. A single post-stroke injection protected neurons from microglial attack in a preclinical model, reducing neuronal loss. |
Individualized ovarian, brain cancer therapies Posted: 16 May 2018 10:12 AM PDT Researchers have discovered that a molecular communication pathway -- thought to be defective in cancer -- is a key player in determining the effectiveness of measles virus oncolytic cancer treatment in ovarian and aggressive brain cancers. This discovery enabled researchers to develop an algorithm to predict treatment effectiveness in individual patients. |

Diagnosing breast cancer with an imaging pill Posted: 16 May 2018 09:37 AM PDT For women, mammograms are a sometimes uncomfortable, but necessary, annual ritual. But this procedure doesn't always provide accurate results, and it exposes women to X-rays. In a new study, scientists report that they have developed a non-invasive 'disease screening pill' that can make cancerous tumors light up when exposed to near-infrared light in mice without using radiation. |
Beef peptides block bitter tastes Posted: 16 May 2018 09:37 AM PDT From burgers to steaks, beef has a long history of being a delicious part of dinner. But what if that pleasant experience of eating beef could extend beyond the dinner plate? Now, one group reports that beef protein, when broken down into peptides, can block bitter taste receptors on the tongue. Such peptides could someday be used to make other foods and even medicines taste better. |
Intimacy in later life does not slow memory loss Posted: 16 May 2018 09:37 AM PDT Older people who enjoy a sexually active and emotionally close relationship with their partner tend to perform better at memory tests than sexually inactive older adults on a short-term basis, but this is not the case over a longer period of time. This is according to a study using data from more than 6000 adults aged 50 and over. |
