Since the first states legalized recreational marijuana in 2012, several others have joined them, and cannabis-infused edibles, including gummy bears, cookies and chocolates, have flooded the market. But these sweet treats have created confusing results for scientists trying to analyze their potency and purity. Now researchers report that components in chocolate might be interfering with cannabis
For years, scientists have been trying to solve a medical mystery: Why do people with diabetes have an increased risk of developing some forms of cancer? Today, researchers report a possible explanation for this double whammy. They found that DNA sustains more damage and gets fixed less often when blood sugar levels are high, thereby increasing cancer risk.
Adjust to the dark and you can peer 2.5m years into the past to see our nearest spiral galaxy, Andromeda This week, try spotting the furthest thing are you will see with the unaided eye. The Andromeda galaxy is a collection of a trillion stars lying 2.5m light years distant. Also known as M31, it is the nearest large galaxy to the Milky Way. Once you have located this admittedly faint object, you
At the Group of Seven meeting in Biarritz, France, there are, in effect, two different summits underway—one that's happening in President Donald Trump's mind, and another that is actually happening on the ground; there's the summit Trump is trying to will into existence, and the summit unfolding in real time. To hear Trump tell it, predictions that the weekend summit would be contentious were all
Whenever I introduce myself as a witch who writes about witches , conversation often turns to The Wizard of Oz , and when it does I'm always tempted to focus on the movie's verdant villain. Many fans delight in the Wicked Witch of the West's deranged cackle and her lust for power and ruby pumps. Even when she meets her demise at Dorothy's hands, she goes down in style, seething: "Who would have t
Runt jorden snurrar idag ungefär en miljon skrotdelar i storlek 1cm och uppåt. De kommer svepande i bortåt 29.000 km/tim, och om de träffar satelliter vi behöver för till exempel kommunikationer och väderprognoser så kan dessa förstöras. Något måste göras för att städa upp. Olika idéer testas, men de är alla svåra och dyra.
The field of plant neurobiology studies the complex behavior of plants. Plants were found to have 15-20 senses, including many like humans. Some argue that plants may have awareness and intelligence, while detractors persist. None Do plants have feelings? Not in a poetic, metaphorical sort of way but real feelings? Can they hate, love, or be bored? If you go around plucking flowers or mowing gras
A colleague of mine and I have recently decided to tackle a project which we think has important ramifications for the field of artificial intelligence. We're vaguely aware that relevant work has been done at places like Carnegie Mellon and are hoping to get some guidance. Our two overarching goals are to discover how models are constructed and to develop a model 'calculus' describing how an agen
Dr Peter Trewby questions the risk-reduction figures of the Iran study and Oliver Lepen says the focus must be on preventing disease, not medication Your headline ( Single polypill reduces risk of heart attacks and strokes, study finds , 23 August) should really have been tempered by quoting the absolute rather than the relative risk-reduction figures. The 34% reduction in major cardiac events yo

Melanoma is a deadly form of skin cancer that has been increasing in the U.S. for the past 30 years. Nearly 100,000 new cases of melanoma are diagnosed every year, and 20 Americans die every day from it, according to the American Academy of Dermatology. Now, researchers have developed a fast-acting skin patch that efficiently delivers medication to attack melanoma cells. The device, tested in mice
In 2012, Washington and Colorado became the first states to legalize recreational marijuana. Since then, several other states have joined them, and cannabis-infused edibles, including gummy bears, cookies and chocolates, have flooded the market. But these sweet treats have created major headaches for the scientists trying to analyze them for potency and contaminants. Researchers now report that co
Two of the industries involved in the infernos consuming the Amazon rainforest and drawing the attention of global powers gathered at the G7 meeting in France are familiar to diners worldwide: soy and beef.

When starlight from billions of years ago zips across the universe and finally comes into focus on Earth, astronomers want their telescopes to be in the best locations possible to see what's out there.
Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us. In nature, properties of Particle B may be depend on what we choose to measure or m
Updated on August 25, 2019 at 12:19 p.m. ET For a long time, elected officials in Washington maintained a rough consensus on Israel. The United States and Israel were unquestioned allies. Military and aid packages were guaranteed winners in Congress. And support for Israel was bipartisan. Following the Six-Day War in 1967, when the country's survival seemed imminently threatened, Jewish organizat
We're a long way from the halcyon days of the early internet, when the promise of a decentralized digital communications network meant anyone could talk to anyone without appealing to the gatekeepers. Knowledge would be liberated from elite newsrooms and stodgy old encyclopedia sets. "Information wants to be free" was the slogan of the day. We've since learned "free" information often has a price
In 1991, an 18-year-old named Marcus Robinson, along with a friend, carjacked a white teenager, who was later found dead at a construction site. At trial, Robinson and his accomplice each said the other had shot the victim. Both Robinson and the friend were black, and race immediately became a hallmark of the prosecution's strategy in Robinson's trial. During jury selection, John Dickson, the pro
What about a system of solar-powered automated drones that orbit around the rainforest in order to avoid future deforestations? It would follow the same logic of satellites around the earth. What do you think? submitted by /u/lwhite99 [link] [comments]
Scientists have found a link between the 'roundness' distribution of tsunami deposits and how far tsunamis reach inland. They sampled the 'roundness' of gravel from different tsunamis in Koyadori, Japan, and found a common, abrupt change in composition approximately 40% of the 'inundation distance' from the shoreline, regardless of tsunami magnitude. Estimates of ancient tsunami size from geologic

Three days ago I argued that if Donald Trump were in any consequential job other than the one he now occupies—surgeon, military commander, head of a private organization or public company, airline pilot—he would already have been removed. A sampling of reader response: The military would have responded. One reader writes: I am retired military officer and there IS a significant part of his behavi
For years, I laughed off guns. They were part of the scenery where I grew up in Chicago. Street gangs fought each other with switchblades and brass knuckles and sometimes you heard the pop of gunfire at night. I shrugged it off. Made jokes about the situation. Closed my eyes and went to sleep. In America, we "go ballistic" when we get angry. We "shoot from the hip" when we talk out of turn. We ha
Boris Johnson has spent the first month of his premiership holding bilateral talks with Britain's allies in the European Union and in the United States. But can he appeal to both at once? At this weekend's Group of Seven summit in the French seaside town of Biarritz, he has endeavored to do just that. The annual gathering, which brings together leaders from Britain, Canada, France, Germany, Italy
When Senator Kamala Harris is criticized for actions she took as San Francisco's district attorney or as California's attorney general, the Democratic presidential hopeful responds in two ways. She cites the most progressive aspects of her record, arguing that she'll advocate in the White House for more reforms to the criminal-justice system. And she asserts that it is laudable to work for change

We've already seen that our career politicians have totally failed to address climate change, on both sides of the isle, there has been a consistent failure by our governments to address the issue, and I think that has to do with the fact that most of our politicians are some form of elites who won't feel the effects for some time, and thus, don't care enough to try to stop it. I believe that in
Does this seem doable? For example, say they collected resources in space, and crushed it into softball sized pieces. Then they filled a giant (kevlar/carbon fiber?) sack covered in heat shielding for the re-entry. The heat shields are built to burn up in the atmosphere – just as re-entry is complete. Then the softball-sized pieces harmlessly (hopefully) rain down on the uninhabited desert below.
