It was going to be Donald Trump’s “ easiest ” meeting, at least according to Trump himself. After a week of tense exchanges with allies in Brussels and then the U.K., the U.S president would head to Helsinki for his first formal summit with Russian President Vladimir Putin. Then on Friday, right as the president was settling down to tea with the Queen, the indictments came; the Justice Department
Researchers say they may be able to estimate how glaciers moved by examining how the weight of the ice sheet altered topography and led to changes in the course of the river.
The concentration of enterococci, bacteria that thrive in feces, has long been the federal standard for determining water quality. Researchers have now shown that the greatest influences on that concentration are the quantity of mammalian feces in the water, and the numbers of enterococci that glom onto floating particulate matter.
Researchers have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of sulfides is a commercially important process with broad applications ranging from chemicals production to environmental management.
Each memory is stored in a specific population of neurons called engram cells. When a memory is linked with another to generate an associative memory, two memory traces overlap. At the same time, individual memories maintain their own identities. Using two overlapping fear memories in mice, researchers show that synapse-specific plasticity guarantees both storage and identity of individual memorie
Researchers have discovered that being initially uncertain when faced with making critical mission-related decisions based on various forms of information may lead to better overall results in the end.
Almost all mammals avoid eating chili peppers and other 'hot' foods, because of the pain they induce. But not the tree shrew, according to a new study. The researchers found that this close relative of primates is unaffected by the active ingredient in chili peppers due to a subtle mutation in the receptor that detects it.
A new method allows researchers to systematically identify specialized proteins called 'nuclesome displacing factors' that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.
A new way to examine stress and inflammation in the heart will help Parkinson's researchers test new therapies and explore an unappreciated way the disease puts people at risk of falls and hospitalization.
Research in mice shows that a pharmacological strategy can alleviate multiple behavioral and cellular deficiencies in a mouse model of fragile X syndrome, the most common inherited form of intellectual disability.
When it comes to diagnosing a condition in which the plasma cells that normally make antibodies to protect us instead become cancerous, it may be better to look at the urine as well as the serum of our blood for answers, pathologists say.
Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods – opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to researchers.
Graphene coatings may offer the ability to control the water evaporation process from various surfaces, according to new research. The study looked at the interactions of water molecules with various graphene-covered surfaces.
Expanding the number of grammar schools is unlikely to promote social mobility by providing more opportunities for disadvantaged pupils, a new study finds.
Army ant (Eciton) soldiers are bigger but do not have larger brains than other workers within the same colony that fulfill more complex tasks, according to a new study. A collaborative team of researchers suggests that because the very specific and limited tasks soldiers fulfill place limited cognitive demands on them, investment in the development of brain tissue is also limited.
New research shows how financial incentive programs can create vital habitat for waterbirds, filling a critical need in drought years. Researchers used satellite images to evaluate two issues: 1) the impact of the 2013-2015 drought on waterbird habitat in the Central Valley; and, 2) the amount of habitat created by incentive programs.
Neutrality may be a tenable position in geopolitics, but it’s tantamount to indifference when tuning into the World Cup. A soccer match can rarely be watched in earnest without one side winning you over. Croatia faces France in the World Cup final on Sunday, a game that (based on figures from the last tournament) could attract a global TV audience of more than one billion people , most of whom, o

As we flooded out Paris into the streets to celebrate France’s World Cup semifinal victory Tuesday night, I saw, here and there, people wearing jerseys from 1998. They are looser than the ones they sell now, a brighter blue, with a red stripe and a white collar. On the backs are the names of an older generation of players—Zidane, Thuram, Henry—who in that year won France’s first and only World Cu

Conventional wisdom decrees that red-state Democratic senators running for reelection are politically screwed, regardless of how they vote on Supreme Court nominee Brett Kavanaugh. If they signal thumbs-up, they’ll infuriate the party’s progressive base and dampen the Democratic turnout they’ll badly need.

Donald Trump rode to Washington, D.C., on a pledge to “drain the swamp,” but so far his administration has luxuriated in the filth. Trump’s hotels have made a mint from bookings related to government business. And with the president’s tax returns still under lock and key, it remains unclear how the Trump Organization may be profiting from his various policies. Meanwhile, former EPA Administrator
Data collected by NASA's Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano on the small moon of Jupiter.
