Neutron 'splashes' reveal signature of exotic particles Posted: 07 Apr 2016 07:15 PM PDT |
Climate models underestimate global warming by exaggerating cloud brightening Posted: 07 Apr 2016 07:14 PM PDT |
Origin of life: An artificial comet holds the missing piece Posted: 07 Apr 2016 12:56 PM PDT Researchers have for the first time shown that ribose, a sugar that is one of the building blocks of genetic material in living organisms, may have formed in cometary ices. They propose the first realistic scenario for the formation of this key compound, which had never been detected in meteorites or cometary ices until now. Their findings shed new light on the emergence of life on Earth. |

Spending that fits personality can boost well-being Posted: 07 Apr 2016 12:55 PM PDT Money could buy happiness if your purchases fit your personality, according to a new study that examines nearly 77,000 actual UK bank spending transactions. The study revealed that people who spent more money on purchases that aligned with their personality traits reported greater life satisfaction. Spending-personality fit was more strongly associated with life satisfaction than were either total income or total spending. |
How manufacturers win by not playing the field Posted: 07 Apr 2016 12:10 PM PDT |
Rare meets common: Reacting protactinium with ubiquitous water explains an elemental oddity Posted: 07 Apr 2016 12:10 PM PDT |
Oil and gas wastewater disposal may harm West Virginia waterways Posted: 07 Apr 2016 12:08 PM PDT Unconventional oil and gas operations combine directional drilling and hydraulic fracturing, or 'fracking,' to release natural gas and oil from underground rock. Studies have centered on potential water pollution from this process that may increase endocrine disrupting chemicals in surface and ground water. Now, researchers report high levels of EDC activity in the surface water near a hydraulic fracturing wastewater disposal facility in West Virginia. |
New survey on American attitudes toward Zika virus finds limited awareness or concern Posted: 07 Apr 2016 12:07 PM PDT A surve finds that three-quarters of Americans who have heard at least a little about the Zika virus are aware that the virus is linked to birth defects in babies born to infected mothers. However, the survey found that most Americans are unclear about the availability of tests to diagnose Zika and whether or not preventative vaccines and effective medicines exist to treat it. |
Methods used to create textiles also could help manufacture human tissues Posted: 07 Apr 2016 12:07 PM PDT Tissue engineering is a process that uses novel biomaterials seeded with stem cells to grow and replace missing tissues. When certain types of materials are used, the 'scaffold' that are created to hold stem cells eventually degrade, leaving natural tissue in its place. Scientists have recently tested new methods to make the process of tissue engineering more cost effective and producible in larger quantities. |
Primate evolution in the fast lane Posted: 07 Apr 2016 12:07 PM PDT The pace of evolution is typically measured in millions of years, as random, individual mutations accumulate over generations, but researchers have uncovered a new mechanism for mutation in primates that is rapid, coordinated, and aggressive. The discovery raises questions about the accuracy of using the more typical mutation process as an estimate to date when two species diverged, as well as the extent to which this and related enzymes played a role in primate evolution. |

Function of mysterious RNAs may often lie in their genes Posted: 07 Apr 2016 12:07 PM PDT Scientists have determined that one prominent long non-coding RNA may be a 'red herring,' with no evident biological role to play -- whereas the DNA from which it originates does perform an important function, as an 'enhancer' that stimulates the expression of an important protein-coding gene nearby. |
Report shows how to say goodbye to harmful algal blooms Posted: 07 Apr 2016 12:06 PM PDT |
New predictive tool for assessing breast cancer risk Posted: 07 Apr 2016 12:06 PM PDT Women were five times as likely to develop cancer if they had a higher percentage of Ki67, a molecular marker that identifies proliferating cells, in the cells that line the mammary ducts and milk-producing lobules, researchers have shown. These cells, called the mammary epithelium, undergo drastic changes throughout a woman's life, and the majority of breast cancers originate in these tissues. |
Safer stem cell-derived therapy for brain radiation recovery Posted: 07 Apr 2016 12:06 PM PDT |
Light and sound waves used to control electron states Posted: 07 Apr 2016 12:06 PM PDT |
Six to 10 million years ago: Ice-free summers at the North Pole Posted: 07 Apr 2016 12:06 PM PDT A new window has been opened into the climate history of the Arctic Ocean. Using unique sediment samples from the Lomonosov Ridge, the researchers found that six to 10 million years ago the central Arctic was completely ice-free during summer and sea-surface temperature reached values of 4 to 9 degrees Celsius. |
From IT to black holes: Nano-control of light pioneers new paths Posted: 07 Apr 2016 12:06 PM PDT A research team has achieved unparalleled levels of control over the angular momentum (AM) of light in an integrated nanophotonic chip. The work leads the way for compact on-chip AM applications like ultra-high definition display, ultra-high capacity optical communication and ultra-secure optical encryption, and could also be used to help scientists better understand the evolution and nature of black holes. |

Quantum simulation 2.0: Atoms chat long distance Posted: 07 Apr 2016 12:03 PM PDT |
Canvassing conversations reduce transphobia Posted: 07 Apr 2016 12:03 PM PDT Researchers report that volunteer canvassers -- both transgender and not -- reduced voters' prejudice against transgender people. Last year the researchers triggered fierce debate about the need for transparency in social science research when they raised doubts about a now-retracted study of the Los Angeles LGBT Center's door-to-door canvassing on gay marriage by other researchers that appeared in Science. They discovered irregularities in that study's data while conducting this follow-up study. |

HIV can develop resistance to CRISPR/Cas9 Posted: 07 Apr 2016 10:23 AM PDT The CRISPR/Cas9 gene-editing platform may need more tweaking before it can be used as an effective antiviral, reports a new study. Researchers who used CRISPR/Cas9 to mutate HIV-1 within cellular DNA found that while single mutations can inhibit viral replication, some also led to unexpected resistance. The researchers believe targeting multiple viral DNA regions may be necessary for the potential antiviral aspect of CRISPR/Cas9 to be effective. |
Run for your life: Exercise protects against cancer Posted: 07 Apr 2016 09:14 AM PDT When you're pounding along an icy pavement or sweating through a gym workout, you try to remind yourself of the many health benefits of exercise. Between gasps, you can say that a healthy, fit lifestyle helps prevents obesity, a worldwide problem of increasing magnitude that has been linked to cardiovascular disease and diabetes. But here's one more—exercise may decrease cancer incidence and slow the growth rate of tumors. |

Crumpling approach enhances photodetectors' light responsivity Posted: 07 Apr 2016 08:18 AM PDT Researchers have demonstrated a new approach to modifying the light absorption and stretchability of atomically thin two-dimensional (2-D) materials by surface topographic engineering using only mechanical strain. The highly flexible system has future potential for wearable technology and integrated biomedical optical sensing technology when combined with flexible light-emitting diodes. |
Radiation therapy chemotherapy combination improves survival in adults with low-grade brain cancer Posted: 07 Apr 2016 08:18 AM PDT Patients with a low-grade type of brain tumor called glioma who received radiation therapy plus a chemotherapy regimen, including procarbazine, lomustine and vincristine (PCV), experienced a longer progression-free survival and overall survival than patients who received radiation therapy alone, according to the results of the clinical trial. |
Researchers combine drugs to develop a new treatment for human parainfluenza virus Posted: 07 Apr 2016 08:18 AM PDT |
Report recommends ways to break cycle of domestic violence Posted: 07 Apr 2016 08:18 AM PDT |
Protein SIRT5 linked to healthy heart function Posted: 07 Apr 2016 08:18 AM PDT A strong connection between a protein, SIRT5, and healthy heart function has been identified by researchers. SIRT5 has the ability to remove a harmful protein modification known as lysine succinylation, which robs the heart of its ability to burn fatty acids efficiently to generate the energy needed for pumping. |
Protein may be responsible for damage in eosinophilic esophagitis, study finds Posted: 07 Apr 2016 08:17 AM PDT Scientists have identified a protein that may be the cause of tissue damage in patients with eosinophilic esophagitis (EoE). EoE is a food allergy-related disease in which white blood cells called eosinophils accumulate in the esophagus, often causing difficult or painful swallowing, nausea, vomiting and poor growth in children and adults. Further understanding of the role of this protein, calpain 14, may lead to potential therapies for EoE. |
