A pre-clinical study with mice found that an existing drug, Venetoclax, that is used to treat blood cancer can kill hibernating HIV cells. If this is confirmed in clinical tests, the discovery might result in a cure for HIV. related: #HIV #treatment |

| A new study found that 50 percent of people who suffer a sudden cardiac arrest show symptoms 24 hours before. The most important symptom for women is a shortness of breath and for men chest pain. A better prediction could lead to a better prevention of the life threatening condition. related: #prediction #cardiac_arrest #prevention |
In lithium batteries, lithium ions may build up on the surface of the battery's negative electrode. If a lot of them accumulate, this may damage the battery, lead to its failure, or even its explosion. Now a better understanding has been achieved that can be used to reduce the problem, potentially extending the lifetime of lithium batteries and speeding up their charging. related: #lithium #battery #lifetime |

| In an accident six children and two adults were trapped in a cable car in Pakistan about 274 metres above the ground in high winds after lines snapped. All persons on board could be rescued in a twelve hour rescue operation using a helicopter and zip lines. related: #cable_car #rescued |
A new study found that a healthy diet with reduced intake of red meat and more time spent on reading and sports are linked to better reasoning skills of children in their first two school years. related: #healthy_lifestyle #reasoning_skills |

| In a new study archaeologists find support for the view that women played an active role as prehistoric hunters by studying prehistoric weapons. They found that women today are as good at throwing the weapons as men. related: #equality #hunter #weapon |
Using the CRISPR technique of gene-editing a virus related to HIV has been removed from non-human primates after a single injection. This gives hope that a similar approach may also work for the AIDS causing HIV virus. related: #AIDS #HIV #CRISPR |

200 water voles that were bred in captivity have been released in the Lake District, England, in order to reestablish the species in the area, after they were nearly wiped out there. related: #water_vole |
A new biology-based small battery has been developed that is using bacteria and could provide small devices such as LED-lights with electricity for many decades when swallowed and getting wet. related: #battery #bacteria #long_lasting |

| Krill are small animals of typically about one to two centimetres. However, they live in huge swarms and eat a lot of plankton and excrement annually bound carbon dioxide combined of estimated 23 megatons of carbon corresponding to the emission of 35 million cars. The WWF calls for better protection of krill. related: #krill #carbon_capture |
In a new study cardiovascular indicators (heart rate and blood pressure) were looked at in people that had sleep restricted to five hours per night compared to those that could sleep up to ten hours. It has been found that reduced sleep is detrimental to cardiovascular health, even if some catch-up (e.g., on weekends) is done. related: #sleep #cardiovascular_health |

How people feel about their own sleep is important for their well-being and more important than some objective quality of sleep as measured by some technology, new research finds. related: #sleep #well_being |

In artificial water reservoirs organic material transforms to methane that is very damaging to the climate. Now a prototype device has been developed that can suck in most of it and use it for the production of electricity. related: #methane #absorption |

| As a measure to reduce food waste, in Geneva, Switzerland, there is a project supported by the city and charities to provide refrigerators so that shops and restaurants can donate their leftover fruit, vegetables, bread, and other perishables in the fridges and any passerby can serve themselves free of charge. related: #food_waste #donation |

| Denial of service attacks flood a service with numerous queries so that genuine requests cannot processed any more. Detection often relies on thresholds which may cut out genuine requests when the genuine demand rises strongly. A new better test is based on the concept of entropy, more precisely a mismatch of the entropy between target addresses and source addresses. related: #dos #denial_of_service_attack #detection |
Using different techniques, glasses have been developed that can in real time receive Bluetooth messages and transcribe them to augmented reality projections within the glasses. This enables deaf people to communicate and at the same time to be free to look wherever they like. related: #deaf #transcription #glasses |

In scrambler therapy, electrical stimulation via electrodes is done in body areas adjacent to that of chronic pain, thereby scrambling the pain signals. In 80 to 90 percent of the patients this can lead to a lasting pain relief, new research finds. related: #scrambler #pain_relief |
