The profits of electricity distribution companies are paid out “in dividends to the local municipalities that own shares in t
Bet hedging' explains the efficacy of many combination cancer therapies ::::: At a glance: Survival benefits of many cancer drug combinations are not due to drug synergy, but to a form of "bet hedging." Combination treatment gives each patient multiple chances of responding to at least one drug, increasing overall measures of survival within patient populations. Computational models of combinations in which drugs act independently of each other accurately predict survival.

Beyond Bitcoin: How Technology Could Help Fix Our Broken Financial System ::::: On a spring day more than 5,000 years ago in the Mesopotamian city of Ur, a foreign merchant sold his wares in exchange for a large bundle of silver. He didn't want to carry the bundle home because he knew he'd be back in Ur again to buy grain at the end of harvest season. Instead the merchant walked to the local temple, where valuables were often stored, and asked the priest to hold onto the sil

One of the problems is that there are many different flu viruses circulating around the world and which ones circulate changes over time. Each year, pharmaceutical companies prod
How well will the flu vaccine work this winter? ::::: Scientists have predicted which H3N2 variants would become 'vaccine resistant', and this prediction has been confirmed during the 2017 Australian flu season. The results published suggest that the current flu vaccine will work better during the 2018 US flu season than the 2017 Australian flu season.
How your brain singles out 1 sound among many ::::: Researchers have developed a new way to find out how the brain singles out specific sounds in distracting settings, non-invasively mapping sustained auditory selective attention in the human brain. The study lays crucial groundwork to track deficits in auditory attention due to aging, disease, or brain trauma and to create clinical interventions, like behavioral training, to potentially correct o
How Zika virus induces congenital microcephaly ::::: Epidemiological studies show that in utero fetal infection with the Zika virus (ZIKV) may lead to microcephaly, an irreversible congenital malformation of the brain characterized by an incomplete development of the cerebral cortex. However, the mechanism of Zika virus-associated microcephaly remains unclear. Scientists have now identified a specific mechanism leading to this microcephaly.

It's Not That Hard To Avoid Normalizing Nazis ::::: Why is it that, in America in 2017, the question of how not to normalize Nazis provokes heated debate? Is there a way to discuss the everyday life of fascists without normalizing? Although there are no quick and easy rules to follow, there are lessons—plenty of them—to be gleaned from history. The most powerful lessons emerge from the press coverage of the Third Reich, especially the soft-focus p
It's Time for Science and Academia to Address Sexual Misconduct ::::: Why do most academic fields, and science in particular, have such significant gender and racial imbalances?

McLaren's Senna Supercar Delivers Wild Performance, Costs a Million Dollars ::::: Usually, when you spend more than a million dollars on something, you get a whole lot of it. A whole lot of diamond necklace, a whole lot of beluga caviar, a whole lot of Instagram followers. But if you’re buying the McLaren Senna, you don’t get much supercar at all. Named for legendary Formula 1 driver Ayrton Senna , McLaren’s latest car is an exercise in million-dollar minimalism. No fancy feat
Mechanism identified of impaired dendritic cell function that weakens response to cancer ::::: PHILADELPHIA — (Dec. 14, 2017) — A new study from The Wistar Institute revealed the mechanism implicated in the defective function of tumor-associated dendritic cells (DCs), a specialized type of immune cells that expose the antigens on their surface to activate the T cells. The new findings explain why DCs are not effective in executing a specialized process that is required for inducing antit

Teen Use of Marijuana May Lead to Bipolar-Like Symptoms Later on in Life ::::: While the effects of marijuana use on fully grown adults is still being debated, the impact on teens is becoming clearer. For decades, researchers have been trying to discover if marijuana use has any negative effects on adolescents. This is important because the teen years are when people usually start to experiment with it. One in three high school students use the drug, a recent survey found.
Teenagers with incontinence are at risk of underachieving at secondary school ::::: Continence problems are among the most common paediatric health problems.

The immune cells that help tumors instead of destroying them ::::: Lung cancer is the leading cause of cancer-associated deaths. One of the most promising ways to treat it is by immunotherapy, a strategy that turns the patient's immune system against the tumor.

These weather events turned extreme thanks to human-driven climate change ::::: NEW ORLEANS — For the first time, scientists have definitively linked human-caused climate change to extreme weather events. A handful of extreme events that occurred in 2016 — including a deadly heat wave that swept across Asia — simply could not have happened due to natural climate variability alone, three new studies find. The studies were part of a special issue of the Bulletin of the America
This human-sized penguin isn't even the largest ancient penguin we know about ::::: Imagine you’re in New Zealand during the late Paleocene, around 60 million years ago.

This is the oldest fossil of a plesiosaur from the dinosaur era ::::: The skeleton of Rhaeticosaurus Georg Oleschinski By Michael Le Page The long-necked marine reptiles known as plesiosaurs are one of the icons of the dinosaur age.

The fossil shows that, as predicted, plesios
This tiny South Pacific Island should be dead by now, but it’s still alive and kicking ::::: We all thought it would only survive for a few months when it was born in a blast of ash in January 2015. The island, Hunga Tonga-Hunga Ha'apai, emerged from the waters in the Kingdom of Tonga, rising nearly 400 feet above the sea, directly between the islands Hunga Tonga and Hunga Ha’apai. Researchers quickly directed satellites to take pictures of the new land, certain that it would suffer the

Vasohibins encode tubulin detyrosinating activity ::::: Tubulin is subjected to a number of posttranslational modifications to generate heterogeneous microtubules. The modifications include removal and ligation of the C-terminal tyrosine of -tubulin. The enzymes responsible for detyrosination, an activity first observed 40 years ago, have remained elusive. We applied a genetic screen in haploid human cells to find regulators of tubulin detyrosination.
Vasohibins/SVBP are tubulin carboxypeptidases (TCPs) that regulate neuron differentiation ::::: Reversible detyrosination of α-tubulin is crucial to microtubule dynamics and functions, and defects have been implicated in cancer, brain disorganization, and cardiomyopathies.
