Genetic study improves lifespan predictions and scientific understanding of aging

By studying the effect of genetic variations on lifespan across the human genome, researchers have devised a way to estimate whether an individual can expect to live longer or shorter than average, and have advanced scientific understanding of the diseases and cellular pathways involved in aging.

PTSD symptoms improve when patient chooses form of treatment

A new study is the first large-scale trial of hundreds of PTSD patients, including veterans and survivors of sexual assault, to measure whether patient preference in the course of treatment impacts the effectiveness of a type of cognitive behavioral therapy and use of selective serotonin reuptake inhibitors, a type of antidepressant often prescribed for PTSD.

Does herpes cause Alzheimer's?

Herpes is the dreaded 'gift that keeps on giving'. But could it also be taking our memories? Decades of research show a striking correlation between Alzheimer's disease risk and infection with Herpes Simplex Virus 1 (HSV1) in people carrying a specific gene. Now, newly-available epidemiological data provide a causal link between HSV1 infection and senile dementia -- raising the tantalizing prospec...

How to avoid raising a materialistic child

If you're a parent, you may be concerned that materialism among children has been on the rise. But there's some good news. A new study suggests that some parenting tactics can curb kids' materialistic tendencies.

New cell movement process key to understanding and repairing facial malformations

The embryonic stem cells that form facial features, called neural crest cells, use an unexpected mechanism of moving from the back of the head to the front to populate the face, finds a new study.

Nanocages in the lab and in the computer: How DNA-based dendrimers transport nanoparticles

How to create nanocages, i.e., robust and stable objects with regular voids and tunable properties? Short segments of DNA molecules are perfect candidates for the controllable design of novel complex structures. Physicists investigated methodologies to synthesize DNA-based dendrimers in the lab and to predict their behavior using detailed computer simulations.

Weight loss success linked with active self-control regions of the brain

New research suggests that higher-level brain functions have a major role in losing weight. In a study among 24 participants at a weight-loss clinic, those who achieved greatest success in terms of weight loss demonstrated more activity in the brain regions of the lateral prefrontal cortex associated with self-control.

Asthma's effects on airways at the single cell level

By sequencing genetic material at a cell-by-cell level, researchers have described how type 2-high asthma affects the airways and results in mucus production with more detail than ever before. These findings, which help move forward scientific understanding of the biology behind asthma and could inform the development of targeted treatments for asthma and other airway diseases.

New insight into the evolution of the nervous system

Pioneering research has given a fascinating fresh insight into how animal nervous systems evolved from simple structures to become the complex network transmitting signals between different parts of the body.

Electrical properties of dendrites help explain our brain's unique computing power

Neuroscientists have discovered that human dendrites have very different electrical properties from those of other species. These differences may contribute to the enhanced computing power of the human brain.

Expanding the optogenetics toolkit

A new molecular engineering technique has the potential to double the number of light-sensitive proteins available for studying brain circuits.

MS genes formerly missing-in-action have been found

Scientists have cracked a tough nut in multiple sclerosis: where are all the genes?

Making gene therapy delivery safer and more efficient

Viral vectors used to deliver gene therapies undergo spontaneous changes during manufacturing which affects their structure and function. As gene therapy approaches become more common for treating disease, managing consistency of the molecular makeup of the virus particles that deliver genes is a key concern in manufacturing on a larger scale.

Brain cells called astrocytes have unexpected role in brain 'plasticity'

Researchers have shown that astrocytes -- long-overlooked supportive cells in the brain -- help to enable the brain's plasticity, a new role for astrocytes that was not previously known. The findings could point to ways to restore connections that have been lost due to aging or trauma.

Insight into how nanoparticles interact with biological systems

Personal electronic devices are a growing source of the world's electronic waste. Many of these products use nanomaterials, but little is known about how nanoparticles interact with the environment. Now chemists have discovered that when certain coated nanoparticles interact with living organisms it results in new properties that cause the nanoparticles to become sticky. Nanoparticles with 5-nanom...

Consumers choose smartphones mostly because of their appearance

The more attractive the image and design of the telephone, the stronger the emotional relationship that consumers are going to have with the product, which is a clear influence on their purchasing decision. After analysing the data collected, the experts indicated that technical characteristics and functionality are the next factors to influence the purchase of smartphones.

Independence tests should ask more of seniors

A psychology researcher says the bar is too low for 'functional independence' in older adults, and should be aligned with skills younger adults must conquer.

Anti-inflammatory drug effective for treating lymphedema symptoms

Two early-stage clinical trials have shown that ketoprofen can improve skin damage in patients with lymphedema.

Why does diabetes cause heart failure?

A new study reveals how, on a cellular level, diabetes can cause heart failure. The findings could lead to medications to treat and perhaps prevent heart failure in diabetes patients.

Novel immune syndrome described

Researchers have discovered a new human immunodeficiency syndrome in two patients on separate continents. The study reveals that a mutation in a gene called IKBKB disrupts the immune system, leading to excessive inflammation and the loss of both T and B white blood cells.

New genetic disease identified

Researchers have discovered a new genetic disease and a method for detecting more unexplained medical conditions.

New approach for controlling dengue fever and Zika virus

To be able to reproduce and become effective disease carriers, mosquitoes must first attain optimal body size and nutritional status. A pair of researchers have succeeded in using CRISPR-Cas9, a powerful tool for altering DNA sequences and modifying gene function, to decrease mosquito body size, moving the research one step closer to eliminating mosquitoes that carry dengue fever and Zika virus.

Hormone alters male brain networks to enhance sexual and emotional function

Scientists have gained new insights into how the 'master regulator' of reproduction affects men's brains.

Ancient Andean genomes show distinct adaptations to farming and altitude

Ancient populations in the Andes of Peru adapted to their high-altitude environment and the introduction of agriculture in ways distinct from other global populations that faced similar circumstances.

Experts raise safety concerns about cardboard baby boxes

Cardboard baby boxes are being promoted for infant sleep as a safe alternative to more traditional cots, bassinets, or Moses baskets, without any evidence in place, warn experts.
