Cuing environmental responses in fungi

Fungi can sense environmental signals and react accordingly, changing their development, direction of growth, and metabolism. Sensory perception lies at the heart of adaptation to changing conditions, and helps fungi to improve growth and recycle organic waste, and to know when and how to infect a plant or animal host.

Researchers show experience plays strong role in early stages of brain circuit development

LA JOLLA, CA - May 26, 2016 - A healthy brain has just the right ratio of cells that enhance signals (excitatory neurons) and cells that tone down signals (inhibitory neurons). These two sets of neurons start out looking exactly the same, so what determines their roles? read more

Potential impact of a dengue vaccine in the Yucatan

While no dengue vaccine has yet been approved for general use, several candidates are in clinical development. Data from the clinical trials can be used in mathematical models to estimate the benefits and risks and of different vaccination strategies. Show More Summary

Well, huh.

Neanderthals built cave structures — and no one knows why Little video at the link which gives a decent overview of the area. The burning certainly points to people doing it, but there are apparently no other artifacts present, which seems very odd to me.

Genes that increase children's risk of blood infection identified

A team led by Oxford University has identified genes that make certain children more susceptible to invasive bacterial infections by performing a large genome-wide association study in African children. read more

Mimicking deep sleep brain activity improves memory

It is not surprising that a good night's sleep improves our ability to remember what we learned during the day. Now, researchers at the RIKEN Brain Science Institute in Japan have discovered a brain circuit that governs how certain memories are consolidated in the brain during sleep. Show More Summary

Making or breaking habits: The endocannabinoids can do it

In our daily lives we constantly have to shift between habitual and goal-directed actions. For example, having to drive to a new place instead of driving home. Difficulties with stopping habits and shifting to goal-directed control underlie a number of neuropsychiatric disorders, including obsessive-compulsive disorder and addiction. Show More Summary

New 'genetic barcode' technique reveals details of cell lineage

By using the gene editing tool CRISPR to create unique genetic "barcodes," it's possible to track the lineage of cells in a living organism, a new study reveals. The development could accelerate our understanding of an array of cellular processes. Show More Summary

Schrödinger's cat is alive and dead in 2 places at once

Through new experiments involving the famous Schrödinger cat state paradox, researchers have shown that a "quantum cat" can be both alive and dead, and in two places at once. The results, which involve inducing a large number of photons...Show More Summary

Mars is emerging from an ice age

Radar measurements of Mars' polar ice caps reveal that the mostly dry, dusty planet is emerging from an ice age, following multiple rounds of climate change. Understanding the Martian climate will help determine when the planet was habitable in the past, how that changed, and may inform studies of climate change on Earth. Show More Summary

A critical inheritance from dad ensures healthy embryos

An important feature for life is what embryos receive from mom and dad upon fertilization. Oddly enough, centrioles, the structures responsible for cell division and flagella movement, are given by the paternal gamete. How oocytes, the maternal gametes, lose centrioles and the importance of doing so for female fertility has been an enigma since the 1930s. read more

Felix Salmon: Peter Thiel’s campaign against Gawker is a template for crushing media

Salmon makes a strong and highly unsettling argument: The next step, after the Hogan verdict, was for Thiel to go public. After the enormous damages were announced and the long appeals process creaked into action, it started to become obvious that Gawker would need to raise more capital in order to continue to be able […]

Odor alternative

Mammals have an exquisitely tuned sensory system that tells them whether they are smelling an orange or a rose. Like keys on a piano keyboard, each component of an odor blend strikes only one chord of olfactory neuron activation. These chords are combined to form a melody that is "heard" in the brain as distinctly citrusy or sweet and flowery. read more

How a huge landslide shaped Zion National Park

SALT LAKE CITY, May 26, 2016 - A Utah mountainside collapsed 4,800 years ago in a gargantuan landslide known as a "rock avalanche," creating the flat floor of what is now Zion National Park by damming the Virgin River to create a lake that existed for 700 years. read more

Using a model to estimate breast cancer risk in effort to improve prevention

A model developed to estimate the absolute risk of breast cancer suggests that a 30-year-old white woman in the United States has an 11.3 percent risk, on average, of developing invasive breast cancer by the age of 80, according to a new study published online by JAMA Oncology. Breast cancer is a common form of cancer diagnosed in women. Show More Summary

NIH study visualizes proteins involved in cancer cell metabolism

Scientists using a technology called cryo-EM (cryo-electron microscopy) have broken through a technological barrier in visualizing proteins with an approach that may have an impact on drug discovery and development. They were able to...Show More Summary

Study identifies risk factors associated with eye abnormalities in infants with presumed Zika virus

In a study published online by JAMA Ophthalmology, Rubens Belfort Jr., M.D., Ph.D., of the Federal University of Sao Paulo and Vision Institute, Sao Paulo, Brazil, and colleagues assessed and identified possible risk factors for ophthalmoscopic...Show More Summary

Slime mold reveals clues to immune cells' directional abilities

How white blood cells in our immune systems home in on and engulf bacterial invaders--like humans following the scent of oven-fresh pizza--has long been a mystery to scientists. But biologists from UC San Diego and the University ofShow More Summary

Science commentary explores ways to pay for success in gene therapy

As a new generation of gene therapy clinical trials shows promise to cure or halt the progression of several rare diseases, the time has come to explore ways to pay for the cutting edge treatments, a pediatric hematologist-oncologist from Dana-Farber/Boston Children's Cancer and Blood Disorders Center argues in a commentary published today by the journal Science. read more

John Innes scientists discover missing link in plant nitrogen fixation process

Scientists at the John Innes Centre have discovered an important component in the process of nitrogen fixation in plants. They have identified a key protein that facilitates the movement of calcium in plant cells. This movement of calcium...Show More Summary
