![]() | Research identifies cells that may be responsible for prostate cancer recurrenceAlthough men with prostate cancer usually respond to standard treatment with hormone therapy or chemotherapy, many will eventually experience progression or recurrence despite treatment—particularly those with high-risk or aggressive forms of the disease. In preclinical laboratory research, a team led by Dean Tang, Ph.D., Chair of Pharmacology and Therapeutics at Roswell Park Cancer Institute has discovered a unique population of normal stem cells that are intrinsically resistant to conventional treatments and may enable prostate cancer relapse. In a new publication in the journal Stem Cell Reports, the team reports its development of a novel preclinical model that allows not only the labeling but also the purification of this rare but persistent population of prostate stem cells, which are dormant and, strikingly, resemble high-risk prostate cancer at the molecular level. |
![]() | Alexa and Siri in our head: Where voice recognition occurs in the brainAmazon recently announced that its language assistant Alexa is now able to recognise voices. What is celebrated as a tech revolution is an everyday process for our brain. So far, it has been unclear as to which areas of the brain we use to differentiate voices. The Max Planck Institute for Human Cognitive and Brain Sciences has just uncovered new findings: Our personal assistant for voice recognition uses a convolution in the right temporal lobe. |

![]() | Researchers recommend specific diets for preventing colorectal cancer in high-risk groupsColorectal cancer is the most prevalent malignant tumour in Spain. It is known that factors such as diet and intestinal inflammation play an important role in its occurrence, but direct links between nutrients, inflammation and colorectal cancer are poorly described. Researchers at the Spanish National Cancer Research Centre (CNIO) have discovered that the amount of protein consumed may be an important factor in the prevention of colorectal cancer in different risk groups. People already suffering from inflammatory bowel disease could benefit from a high-protein diet; however, in contrast, low protein consumption may be the best option for those people who have a genetic predisposition to develop colon cancer. |

Researchers report a new target to treat prostate cancerThe drug Gefitinib is used to treat breast, lung, and other cancers by inhibiting epidermal growth factor receptor (EGFR) signaling, but it has only a limited effect on prostate cancer. EGFR, present on the cell membrane, is involved in cell proliferation and the development of dermis, lung, and digestive tissues. When a mutation causes its over-activation, it can lead to increased cell proliferation and tumor formation. | |
![]() | Experts say these two things are the secret to living a longer life"Blue zones" are areas of the world where people live considerably longer lives. On these territories we can find octogenarians, nonagenarians and many centenarians, and even some supercentenarians (people who have reached the age of 110). |
![]() | Walking might not be good for you if it's through polluted city streetsWe don't see air pollution, unless its concentration is high, and so we don't realise it's there and that we breathe it in. We don't think of the devices we use every day and many times a day: cars, as air pollution sources. |
![]() | Heart disease and stroke deaths decline slightly, new statistics findDeaths from heart disease and stroke have declined slightly, yet both diseases remain among the leading causes of death in the United States, new federal statistics show. |
![]() | Can we turn back the clock on an aging thymus?As we age our thymus shrinks and is replaced by fatty tissue, losing its essential ability to grow and develop T cells and leaving us susceptible to infections, immune disorders and cancers. |
![]() | Support programmes for perpetrators of domestic abuse are controversial, but new research finds they bring benefitsDomestic abuse is a major health and social issue that affects the lives of millions of people, most of them women, across the world. Our recent research shows that programmes to help abusers are proving to be effective in helping men recognise and change their abusive behaviour – and are also value for money. We found that for every £1 spent delivering such a programme, the value to society was £1.40. |

![]() | How odours are turned into long-term memoriesThe neuroscientists Dr. Christina Strauch and Prof Dr. Denise Manahan-Vaughan from the Ruhr-Universität Bochum have investigated which brain area is responsible for storing odours as long-term memories. Some odours can trigger memories of experiences from years back. The current study shows that the piriform cortex, a part of the olfactory brain, is involved in the process of saving those memories; the mechanism, however, only works in interaction with other brain areas. The findings have been published in the journal Cerebral Cortex. |

![]() | Research reveals how climate change may affect Hawaiian fishpond aquacultureFor centuries, indigenous peoples of the Hawaiian Islands practiced sustainable aquaculture by building walled fishponds in coastal estuaries. Historical records estimate that in the early 1900s an extensive network of over 450 fishponds across the Hawaiian Islands produced upwards of 2 million pounds of fish annually and supported large thriving communities. Currently, worldwide aquaculture accounts for almost one-half of fish consumption. |
Two proteins maintain embryonic stem cell pluripotency through different meansTwo 'finger-like' proteins employ different mechanisms to help safeguard the ability of embryonic stem cells to differentiate into a variety of cell types, according to an A*STAR-led study. This finding could help researchers develop new ways to regenerate lost or damaged tissue. | |
![]() | Why we shouldn't be so quick to demonise batsAustralian health authorities regularly issue public reminders not to touch bats because they can host Australian Bat Lyssavirus (ABLV). This type of health education is necessary because it reduces human exposure to bat-borne diseases. However, subsequent sensationalist media reporting risks demonising bats, which increases human-wildlife conflict and poses barriers to conservation. |
![]() | Prehistoric women's skeletons show impact of rigorous manual labourWomen living around 7 000 years ago did a lot of heavy lifting in their early agrarian societies. Now skeletal analysis reveals they were even stronger than the top female athletes of today. |
![]() | Rainbow peacock spiders may inspire new optical technologiesEven if you are arachnophobic, you probably have seen pictures or videos of Australian peacock spiders (Maratus spp.).

![]() | Boat traffic threatens the survival of Panama's Bocas Del Toro dolphinsBottlenose dolphins in Panama's Bocas Del Toro Archipelago should be designated as endangered say the authors of a new study. Biologists working at the Smithsonian Tropical Research Institute discovered that the roughly 80 dolphins in the archipelago do not interbreed with other Caribbean bottlenose dolphins. Their low numbers jeopardize their long-term survival, which is threatened by increasing local boat traffic that killed at least seven dolphins in 2012. |
![]() | New species of marine spider emerges at low tide to remind scientists of Bob MarleyIt was 2am on the 11th of January 2009 when the sea along the coastline of Australia's "Sunshine State" of Queensland receded to such an extent that it exposed a population of water-adapted spiders. The observant researchers who would later describe these spiders as a species new to science, were quick to associate their emergence with reggae legend Bob Marley and his song "High Tide or Low Tide". |
![]() | To mow or not to mow: Tackling nuisance growth of water plants at the rootMassive growth of submerged aquatic plants can be a nuisance, especially in summer. It's up to water managers to limit the inconvenience for swimmers, boats and fishermen in a way that is both responsible and cost-effective. NIOO researcher Michiel Verhofstad defended his PhD thesis this week on the 'root' causes of the problem, and how best to tackle it. |
