Psych News Alert: Anxious Parents Can Transmit Anxiety to Children, Twin Study Shows. The association between parental and offspring anxiety and neuroticism appears to be environmental rather than genetic—that is, children and adolescents learn anxious behaviors from their parents rather than inheriting anxiety genetically.
That’s the conclusion of a remarkable study titled "The Intergenerational Transmission of Anxiety: A Children-of-Twins Study" by Thalia C. Eley, Ph.D., of Kings College London and colleagues at institutions in the United States and Sweden. The study was published in AJP in Advance. Researchers used data from the Twin and Offspring Study of Sweden comprising information on 387 monozygotic twin families and 489 dizygotic twin families. Parental anxious personality was self-reported by twins using 20 items from the Karolinska Scales of Personality. For both anxiety and neuroticism, the models provide support for significant direct environmental transmission from parents to their adolescent offspring.

Scanning ultrasound removes amyloid-β and restores memory in an Alzheimer’s disease mouse model. Most MS Patients Who Received Stem Cell Transplants Still in Remission Years Later. Most of the multiple sclerosis (MS) patients who took part in the cutting-edge stem cell study HALT-MS are still in remission years later.
The phase 2 study has demonstrated impressive results by rebuilding the immune system using a patient’s own stem cells. Studying 24 study volunteers who underwent stem cell transplants between 2006 and 2010, Dr. Scientists discover how to change human leukemia cells into harmless immune cells. “B-cell leukemia cells are in many ways progenitor cells that are forced to stay in an immature state,” Majeti said.
So he, McClellan and student Christopher Dove, an MD/PhD student and the paper’s other lead author, did more experiments and confirmed that methods shown to have altered the fate of the mouse progenitor cells years ago could be used to transform these human cancer cells into macrophages, which can engulf and digest cancer cells and pathogens. There’s big-time interest in differentiation therapies for cancer. In new study, 100 percent of participants taking HIV prevention pill Truvada remained infection-free.

(D Dipasupil/Getty Images for (RED)) As far as emotions go, AIDS researchers tend to be a staid bunch who look skeptically at every new finding. But the results of a study released this week on an HIV prevention drug have many cheering. The study conducted at Kaiser Permanente in San Francisco involved more than 600 high-risk individuals, most of whom were men who have sex with men.

Measles Vaccine Still Doesn't Cause Autism. ShareTweetShareSendLink But a new paper published in JAMA should end debate once and for all.
Ebola vaccine trial proves 100% successful in Guinea. A vaccine against Ebola has been shown to be 100% successful in trials conducted during the outbreak in Guinea and is likely to bring the west African epidemic to an end, experts say.
The results of the trials involving 4,000 people are remarkable because of the unprecedented speed with which the development of the vaccine and the testing were carried out. Scientists, doctors, donors and drug companies collaborated to race the vaccine through a process that usually takes more than a decade in just 12 months. “Having seen the devastating effects of Ebola on communities and even whole countries with my own eyes, I am very encouraged by today’s news,” said Børge Brende, the foreign minister of Norway, which helped fund the trial. “This new vaccine, if the results hold up, may be the silver bullet against Ebola, helping to bring the current outbreak to zero and to control future outbreaks of this kind.

UBC researchers have created the first self-propelled particles capable of delivering coagulants against the flow of blood to treat severe bleeding, a potentially huge advancement in trauma care. "Bleeding is the number one killer of young people, and maternal death from postpartum hemorrhage can be as high as one in 50 births in low resource settings so these are extreme problems," explains Christian Kastrup, an assistant professor in the Department of Biochemistry and Molecular Biology and the Michael Smith Laboratories at the University of British Columbia.
Traditional methods of halting severe bleeding are not very effective when the blood loss originates inside the body like the uterus, sinus or abdomen. "People have developed hundreds of agents that can clot blood but the issue is that it's hard to push these therapies against severe blood flow, especially far enough upstream to reach the leaking vessels. Self-assembling material that grows and changes shape could lead to artificial arteries. News story Researchers at QMUL have developed a way of assembling organic molecules into complex tubular tissue-like structures without the use of moulds or techniques like 3D printing. Monday 28 September 2015 The study, which will appear on Monday 28 September in the journal Nature Chemistry, describes how peptides and proteins can be used to create materials that exhibit dynamic behaviors found in biological tissues like growth, morphogenesis, and healing. The method uses solutions of peptide and protein molecules that, upon touching each other, self-assemble to form a dynamic tissue at the point at which they meet.
As the material assembles itself it can be easily guided to grow into complex shapes. Lead exposure in mothers can affect future generations. From trees to power: McMaster engineers build better energy storage device. McMaster Engineering researchers Emily Cranston and Igor Zhitomirsky are turning trees into energy storage devices capable of powering everything from a smart watch to a hybrid car. The scientists are using cellulose, an organic compound found in plants, bacteria, algae and trees, to build more efficient and longer-lasting energy storage devices or capacitors. Geneticists Found the 'Master Tumor Suppressor' That Stops Cancer in Elephants. A longstanding mystery in biology is why the rate of cancer incidence in a species does not scale up with body size and longevity. Take elephants for instance, which live to approximately the same age as humans and have 100 times more cells, yet hardly ever develop cancer, a disease which is estimated to affect 40 percent of Americans at some point in their lives.
