You can think of DNA as a string of letters—As, Cs, Ts, and Gs—that together spell out the information needed for the construction and function of cells. Each cell in your body shares the same DNA. So, for cells to take on their differing roles, they must be able to turn on and off specific genes with precise control. The genes active in a brain cell, for instance, are different than those active

Defective mitochondria are linked to several critical human genetic diseases, including neurode
The current government shutdown is now the longest on record, sidelining roughly 800,000 non-essential workers in nine agencies out of about two million full-time federal employees in all (excluding postal workers and soldiers). Paul C. Light, a professor of public service at New York University's Wagner Graduate School of Public Service, is a leading expert on the federal service and the author
It's no surprise to scientists that variety is the very essence of biology, not just the seasoning, but most previous studies of key brain cells have found little variability in a common cell process that involves how genetic information is read and acted on.
A study finds a surprising response to cocaine in a novel strain of mutant mice — they failed to show hyperactivity seen in normal mice when given cocaine and didn't run around. In other tests, they still found cocaine appealing, but displayed an inability to shake the memory of cocaine's actions when the drug was no longer administered. The key change that blocks cocaine's stimulant effects in t

Regeringens sundhedsreform byder på nye ydernumre og flere uddannelsespladser til almen medicinere. Når det kommer til de praktiserende læger, er reformen et decideret pletskud fra regeringen, mener PLO-formand.
If you compare historical photos of glaciers with those taken more recently, you can see that where there was formerly ice, there is now very often nothing but rock. Geographers, however, are less interested in the area covered by a glacier, and more interested in its mass. Researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now investigated all glacial areas in South Ame
Hurricanes and tropical storms on the coasts tend to get countrywide airtime for their intensity and impact, but floods in the central part of the U.S. also cause significant damage and disruption. That is certainly true for the Front Range of Colorado. In 1864, a massive flood from the Poudre River destroyed the Camp Collins military post in LaPorte. In 1997, the Spring Creek flood caused $200M i

Around 11,500 years ago, in what is now northeast Jordan, people began to live with dogs and may also have used them for hunting, according to a new study by archaeologists from the University of Copenhagen and University College London. They suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the si
Scientists from Umeå university have shown that the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host. Studying adaption to hypoxic or anoxic niches is particularly fruitful for characterizing the pathogenicity of C. albicans toward the development of better therapeutic approaches. Details about the study are publish
Plasmas—hot gases consisting of chaotically-moving electrons, ions, atoms and molecules—comprise the interiors of stars, but scientists can create them artificially using special equipment in the laboratory. If a plasma comes in contact with a solid, such as the wall of the lab equipment, under certain circumstances, the wall is changed fundamentally and permanently: Atoms and molecules from the p
Green plants, algae and some bacteria use sunlight to convert energy. The pigments in chlorophyll absorb electromagnetic radiation, which induces chemical reactions in electrons. These reactions take place in the nucleus of complex protein structures, referred to by experts as photosystems I and II. The processes that take place in these photosystems are induced by catalysts in a certain order. In

Many people in Australia will head to the beach this summer and that'll most likely include a dip or a plunge into the sea. But have you ever wondered where those ocean waters come from, and what influence they may have?
The ability of cells to adhere to each other and to their environment is the basis for multicellular life. Adhesion occurs via diverse receptors at the surface of cells that bind to specific ligands in their surroundings. Despite the importance of these adhesion receptors, there is a paucity of tools available for precisely controlling their interactions with the environment. To address this limit
The production of entropy, which means increasing the degree of disorder in a system, is an inexorable tendency in the macroscopic world owing to the second law of thermodynamics. This makes the processes described by classical physics irreversible and, by extension, imposes a direction on the flow of time. However, the tendency does not necessarily apply in the microscopic world, which is governe
The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered important new details of how the ear achieves this amazing ability to pick up faint sounds.

The newly available observations show that the year 2018 is the hottest year ever recorded for the global ocean, as evident in its highest ocean heat content since 1950s in the upper 2,000 meters.
Rising temperatures can be charted back to the late 1950s, and the last five years were the five hottest on record Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions. The key to the measurements is the oceans. Oceans absorb more than 90% of the heat that results from greenhouse gases, so if you want to measure global war
Addiction is a learning disorder; it's not a sign that someone is a bad person. Tough love doesn't help drug-addicted people. Research shows that the best way to get people help is through compassion, empathy and support. Approach them as an equal human being deserving of respect. As a first step to recovery, Maia Szalavitz recommends the family or friends of people with addiction get them a comp
President Donald Trump is a unilateralist. He often seems more comfortable condemning allies than adversaries. He prefers to go his own way, walking away from multinational agreements or understandings with relish—witness the Paris Climate accord and the Iran nuclear deal. He makes it clear that he wants out of the Middle East—a region that, he believes, has consumed far too much American blood a
As the longest government shutdown in American history drags on, it's not just hurting the morale of America's federal workforce and the broader American economy . It's hurting our national security. Some of the damage is already plainly apparent—but in four crucial ways, its harms will persist long after the government reopens. We're beginning to see indicators of short-term national- and homela
On September 28, 2018, tech died. That's according to a widely circulated eulogy prepared by Vincent Deluard, a strategist at INTL FCStone, a financial-services company.

When the Financial Times got its hands on the document, it leaned into the dea
In a recent essay , my colleague John McWhorter posited that the current social-justice paradigm is a dead end—that fighting racism and sexism are still necessary, but that the left went astray when it stopped focusing on the sociological project of changing laws and social structures that abolitionists, suffragists, and civil-rights activists had earlier pursued. Today's left is too focused on p

As the humans go about their affairs, living atop a thin crust floating on molten rock, the liquid iron in the Earth's core is churning in strange, erratic ways. This is a problem because those humans, clever in some ways, have figured out that the movement of the liquid iron creates a magnetic field. For centuries, their compasses have pointed "north." But where that is, exactly, is changing. Af
11,500 years ago in what is now northeast Jordan, people began to live alongside dogs and may also have used them for hunting, a new study shows. The archaeologists suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the site.

One notable exception is the vertebrate olfactory receptor neuron (ORN), where the transduction current is carried largely by the anion Cl−. However, it remains unclear why ORNs use an anionic current for signal amplification. We…
Phosphatase PP2A expression levels are positively correlated to the clinical severity of systemic lupus erythematosus (SLE) and IL17A cytokine overproduction, indicating a potential role of PP2A in controlling TH17 differentiation and inflammation. By generating a mouse strain with ablation of the catalytic subunit α of PP2A in peripheral mature T…
Merkel cell polyomavirus (MCV) contributes to approximately 80% of all Merkel cell carcinomas (MCCs), a highly aggressive neuroendocrine carcinoma of the skin. MCV-positive MCC expresses small T antigen (ST) and a truncated form of large T antigen (LT) and usually contains wild-type p53 (TP53) and RB (RB1). In contrast, virus-negative…
The vast complexity of native heteromeric K+ channels is largely unexplored. Defining the composition and subunit arrangement of individual subunits in native heteromeric K+ channels and establishing their physiological roles is experimentally challenging. Here we systematically explored this "zone of ignorance" in molecular neuroscience. Venom components, such as peptide toxins,…

Climate change and animal mimicry Hymenopteran insect (Vespula vulgaris) and Syrphidae mimic (Chrysotoxum festivum). Images courtesy of Steven Falk (photographer). Batesian mimics are organisms with traits that imitate poisonous or otherwise dangerous prey, allowing the mimics to evade predators. Christopher Hassall et al. (pp. 929–933) report that climate change-associated seasonal…
With more than 8,500 journals publishing content deemed worthy of inclusion in Science Citation Index Expanded, the launch of a new journal is not necessarily noteworthy. In fact, the proliferation of open access journals has become problematic, if in no other way than by filling email inboxes of scientists with…
Today, most global economic production depends on energy produced from burning fossil fuels, which emit carbon dioxide as a byproduct. Although the costs of carbon-free energy such as wind and solar have come down dramatically over recent decades, there are substantial challenges to completely decarbonizing our electricity system, and even…
Vast areas of the earth's land surface have been altered by human activities such as clearing native vegetation for agriculture and livestock grazing, logging of natural forests, and land conversion for urban settlements (1). These activities have had profound impacts on biodiversity and on key ecosystem processes (e.g., pollination and…
