The connection between your next flight and climate change is likely clear in your head. More planes emitting greenhouse gases means more global warming. Simple enough, but there's an opposite side that you probably hadn't thought of.
Drylands cover about 41% of the Earth's land surface and host one in three humans inhabiting our planet. In these areas, life is highly influenced by aridity, i.e. the balance between the amount of rainwater and the water lost by evaporation. In this sense, aridity is increasing worldwide as a result of climate change. A study conducted by the Dryland Ecology and Global Change Lab at the Universit
According to official reports, only 14 people died of the coronavirus COVID-19 on Friday — a drastic reduction from the roughly 90 daily fatalities that have been reported each day for the past week. But the sudden drop in deaths is almost certainly the result of clerical changes in how Chinese authorities are reporting both confirmed cases and fatalities — they decided to include in their offici

Memory performance and other cognitive abilities benefit from a good blood supply to the brain. This applies in particular to people affected by a condition known as 'sporadic cerebral small vessel disease'. Researchers suggest that blood perfusion of the so-called hippocampus could play a key role in age- and disease-related memory problems.
The ninefold radial arrangement of microtubule triplets (MTTs) is the hallmark of the centriole, a conserved organelle crucial for the formation of centrosomes and cilia. Although strong cohesion between MTTs is critical to resist forces applied by ciliary beating and the mitotic spindle, how the centriole maintains its structural integrity is not known. Using cryo–electron tomography and subtomo
IP3 receptors (IP3Rs) are calcium channels found in all animal cells. By mediating calcium ion release, IP3Rs integrate signals from different cellular pathways and metabolic states. Not surprisingly, deregulation of IP3Rs causes many diseases.
The open-source program that I use for literature management ( Zotero ) set off a feature not long ago that I didn't realize it had. A red banner appeared across the top with a notice that a paper that I had in one of my collections had been retracted.

However, in neuroblastomas, MYCN amplification and ATRX mutations are mutually exclusive and incompatible.
The low-pressure area that had once been Tropical Cyclone Francisco has been lingering in the Southern Indian Ocean since Feb. 6 when it weakened below tropical cyclone status. Since then, Francisco's remnants moved into an area of warm waters and low wind shear allowing the low-pressure area to re-organize, consolidate and re-form. NASA's Aqua satellite provided forecasters with a visible image o
In a new study, scientists with NASA's Arctic Boreal Vulnerability Experiment (ABoVE) used planes equipped with the Airborne Visible Infrared Imaging Spectrometer — Next Generation (AVIRIS — NG), a highly specialized instrument, to fly over some 20,000 square miles (30,000 square kilometers) of the Arctic landscape in the hope of detecting methane hotspots. The instrument did not disappoint.

Donald Trump's obsession with Ukrainian corruption turned out to be genuine: He wanted it thoroughly investigated—for the sake of its emulation. The diplomats who testified in front in Adam Schiff's committee explained and exposed the Ukrainian justice system. Their descriptions may have been intended as an indictment of kleptocracy, but the president apparently regarded them as an instructional
We haven't talked about Nuvia (no relation to Nvidia) to-date, but I've had an eye on the startup since it came out of stealth mode late last year. Nuvia is a new CPU design company with an impressive industry pedigree, and it intends to challenge Intel and AMD for part of the overall server market, using its own custom ARM-based architecture. That's an eyebrow-raising claim, given how hard it ha

Accountable Care Organizations — or ACOs — formed for the first time in 2011, designed to combat rising medical costs and provide more coordinated care to Medicare patients. But the savings have been inconsistent nationwide. A new Portland State University study looked at what's driving those inconsistencies and what ACOs might do to resolve the issue.
Psychological illusionist Derren Brown presents magic as an analogy for how we process the world around us. In the same way we believe in a trick by forming a narrative around it, we can tell ourselves stories in life. It's important to maintain a sense of skepticism. But it's equally as important to recognize the edges of usefulness in being skeptical. For example, an atheist can be skeptical of
A team headed by Prof. Dr. Frank Stienkemeier and Dr. Lukas Bruder from the Institute of Physics at the University of Freiburg has succeeded in observing in real-time ultrafast quantum interferences—in other words the oscillation patterns—of electrons which are found in the atomic shells of rare gas atoms. They managed to observe oscillations with a period of about 150 attoseconds—an attosecond is

Earlier this week, Lloyd Blankfein, the former head of Goldman Sachs, waded into the presidential race. "If Dems go on to nominate Sanders, the Russians will have to reconsider who to work for to best screw up the US," he wrote on Twitter . "Sanders is just as polarizing as Trump AND he'll ruin our economy and doesn't care about our military. If I'm Russian, I go with Sanders this time around." G
Water is split into hydrogen and oxygen by electrolysis, but if CO2 is also added to the mixture, compounds can be generated to make textiles, diapers and even spirits. American scientists, led by a Spaniard, have developed a catalyst that accelerates this reaction, while also removing a greenhouse gas.
I n 2016 , the Republican Party was formally declared broken . And Donald Trump was proof of its brokenness. If the basic job of a political party is to influence voters by funneling money and endorsements toward the establishment's preferred candidate, Trump proved that the GOP was a hollow shell. Jeb Bush spent $130 million —for nothing. Marco Rubio and Ted Cruz got a slew of fancy endorsements
Most theories of solid state and soft matter physics were developed independently; thus, a few physical concepts are applicable to both. Recent research, however, particularly a study by Elbio Dagotto, found that correlated electrons in solid-state physical systems can sometimes present a spatially inhomogeneous phase accompanied by extraordinarily slow electron dynamics, which resembles a phase o
Most natural and man-made surfaces appear to be rough on many length scales. There is presently no unifying theory of the origin of roughness or the self-affine nature of surface topography. One likely contributor to the formation of roughness is deformation, which underlies many processes that shape surfaces such as machining, fracture, and wear. Using molecular dynamics, we simulate the biaxial
The Islamic State has lost all of its territory; tens of thousands of its fighters have been killed or are imprisoned; and its former leader, Abu Bakr al-Baghdadi, is dead. But a Kurdish leader who witnessed the militant group's rise and fall is warning that ISIS is putting itself back together and stressing an uncomfortable fact: that ISIS is bigger now than it was nearly six years ago, when it
Dressel and Farid recently found that laypeople were as accurate as statistical algorithms in predicting whether a defendant would reoffend, casting doubt on the value of risk assessment tools in the criminal justice system. We report the results of a replication and extension of Dressel and Farid's experiment. Under conditions similar to the original study, we found nearly identical results, wit
For several hundred years, millions of Chinese girls had their bodies painfully misshapen to conform to a prevailing social expectation. Intact feet, girls were told, would damage their marriage prospects. To achieve a more suitable size and shape, young girls' feet were crushed repeatedly over years. Each excruciating procedure forced the girls to learn to walk anew, rereading the ground from an
If I tried wishing a happy Valentine's Day to everyone suggested by the greeting-card aisle, I fear I'd run out of love. On a recent visit to a big-box store in the Washington, D.C., area, I saw greeting cards slotted into categories including "wife" and "husband," as well as, among others, "daughter," "son," "parents," "grandson," "young grandson," "friend," "teacher," and, for the undiscriminat

For nearly two decades, Rodriguez had searched for people and drugs hidden in cargo waiting to get into the
"Pink elephant in the room" time: There is no impending "ice age" or "mini ice age" to be caused by an expected reduction in the Sun's energy output in the next several decades. Through its lifetime, the Sun naturally goes through changes in energy output. Some of these occur over a regular 11-year period of peak (many sunspots) and low activity (fewer sunspots), which are quite predictable. The
Conducting polymer thin films containing inherent structural disorder exhibit complicated electronic, transport, and thermoelectric properties. The unconventional power-law relation between the Seebeck coefficient ( S ) and the electrical conductivity () is one of the typical consequences of this disorder, where no maximum of the thermoelectric power factor ( P = S 2 ) has been observed upon dopi

The embedding of objects into the SMP enables the gripping while the shape
In March 1989, a tripped circuit in the Hydro-Québec power grid left 6 million people without electricity. A week earlier, an unusually harsh snowstorm had strained the region; the day before, a solar flare and accompanying release of plasma and magnetic field sent a mountain of energy propelling toward Earth at a million miles an hour.
In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this problem in his experiments with interacting photons, AMOLF physicist Said Rodriguez thought of a way around it. In an article that will be published in Physical Review Applied,
