| Researchers turn carbon dioxide into sustainable concrete Posted: 22 Mar 2016 01:25 PM PDT Imagine a world with little or no concrete. Would that even be possible? After all, concrete is everywhere -- on our roads, our driveways, in our homes, bridges and buildings. For the past 200 years, it's been the very foundation of much of our planet. But the production of cement, which when mixed with water forms the binding agent in concrete, is also one of the biggest contributors to greenhouse gas emissions. In fact, about 5 percent of the planet's greenhouse gas emissions comes from concrete. |

| How to spot elder abuse and neglect in the ER: Things are not always as they seem Posted: 22 Mar 2016 09:04 AM PDT When older adults in severely debilitated states show up for treatment in the emergency department, emergency physicians and staff must be able to identify and document their symptoms and decide whether to report their concerns to adult protective services. This is a difficult decision as the patient's symptoms may stem from willful neglect, unintentional neglect or sub-acute symptoms caused by an underlying illness than manifest as neglect. |
| Finding a new 'sweet spot' for improving cancer risk assessment Posted: 22 Mar 2016 09:03 AM PDT An environmental toxicologist who has been an outspoken critic of the current linear no-threshold (LNT) approach to risk assessment for radiation and toxic chemicals, now proposes a new approach integrating LNT with hormetic dose-response models. The new strategy, applied to chronic animal bioassays, would reconcile previously conflicting methods to offer 'significant improvements' and maximize public health benefits, he and co-authors say. |

Cognitive behavioral therapy alone was given to 43 participants and the rest received a combination of CBT and MI from therapists trained in both. |
| Many targeted cancer therapies suppress T cell immune responses Posted: 22 Mar 2016 09:00 AM PDT New research has demonstrated that dozens of these targeted therapies suppressed the activity of T cells that could actually help fight tumors. While studying the FDA-approved targeted therapy trametinib, the researchers also found that pairing it with a signaling protein 'superagonist' stimulated T cell activity while preserving the cancer-blocking effects of the cancer treatment. |

While most of the microbes looked similar on Earth and in space, one type of bacteria actually grew much better in space. |
| More ancient viruses lurk in our DNA than we thought Posted: 22 Mar 2016 07:07 AM PDT Think your DNA is all human? Think again. And a new discovery suggests it's even less human than scientists previously thought. Nineteen new pieces of non-human DNA -- left by viruses that first infected our ancestors hundreds of thousands of years ago -- have just been found, lurking between our own genes. |
| Depression study examines levels of 'love' hormone and its impacts on mother-baby emotional bonding Posted: 22 Mar 2016 07:07 AM PDT Widely referred to as the "love" hormone, oxytocin is an indispensable part of childbirth and emotional mother-child bonding.

| Migratory birds disperse seeds long distances Posted: 22 Mar 2016 07:05 AM PDT Some species of plants are capable of colonizing new habitats thanks to birds that transport their seeds in their plumage or digestive tract. Until recently it was known that birds could do this over short distances, but a new study shows that they are also capable of dispersing them over more than 300 kilometres. For researchers, this function could be key in the face of climate change, allowing the survival of many species. |
