Over the last year, the worldwide web has started to look less worldwide.Europe is floating regulation that could impose temporary bans on US tech companies that violate its laws. The United States was on the verge of banning TikTok and WeChat, though the new Biden administration is rethinking that move. India, which did ban those two apps as well of dozens of others, is now at loggerheads with Twitter.And this month, Facebook (FB) clashed with the Australian government over a proposed law that would require it to pay publishers. The company briefly decided to prevent users from sharing news links in the country in response to the law, with the potential to drastically change how its platform functions from one country to the next. Then on Tuesday, it reached a deal with the government and agreed to restore news pages. The deal partially relaxed arbitration requirements that Facebook took issue with.In its announcement of the deal, however, Facebook hinted at the possibility of similar clashes in […]
Green tea has been consumed in China for 4,000 years—and one of its compounds may hold the key to staving off cancer, according to compelling new research.
It switches on a gene called p53, which is proven to block the development of tumors.
Known as the “Guardian of the Genome” for its ability to repair DNA damage and destroy cancerous cells, p53 is classified as a tumor suppressor—and if a person inherits only one functional copy of the p53 gene from their parents, they are predisposed to the disease.
A new study published this month in Nature Communications shows that an antioxidant found in the traditional Chinese drink may increase levels of p53 and improve its efficiency, say scientists at the Rensselaer Polytechnic Institute in Troy, New York.
Studying the direct interaction between p53 and the green tea compound, epigallocatechin gallate (EGCG), offers hope that a new drug might be created to mimic it.
“Mutations in p53 are found in over 50% of human cancer,” said the paper’s author Professor Chunyu Wang, who called it “arguably the most […]
A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday.
The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say. This has implications for everything from the climate of Europe to the rates of sea-level rise along the U.S. East Coast.
Although evidence of the system’s weakening has been published before, the new research cites 11 sources of “proxy” evidence of the circulation’s strength, including clues hidden in seafloor mud as well as patterns of ocean temperatures. The enormous flow has been directly measured only since 2004, too short a period to definitively establish a […]
The Arctic is now open for business year-round after a large commercial ship sailed the Northern Sea Route from Jiangsu, China, to a Russian gas plant on the Arctic coast, for the first time ever during the month of February, when winter temperatures normally make the icy waterway impassable.
The tanker, owned by Russian maritime shipping company Sovcomflot, was able to make the trip through the Arctic sea ice because it is no longer frozen all winter due to human-induced global warming.
The ability to make this trip 365 days a year opens up vast new possibilities for the shipping industry, which carries 80 percent of the world’s cargo by volume and 70 percent of global trade by value. But it also raises concerns about how the scramble to capitalize on the new route could upend geopolitics.
To get a better understanding of what this new possibility in the Arctic means for the rest of the […]
The role of nuclear power in a low-carbon future has been subject to a long and contentious debate. Is a nuclear or a renewables pathway the best way forward, or do we need a “do everything” approach where every deployable technology is rolled out to decarbonise our electricity supply as soon as possible?
Many influential climate scientists and international organisations argue that a global shift towards nuclear power offers the best pathway to tackling the climate emergency and meeting the world’s increasing demands for electricity.
Others argue that renewable sources of energy are the best pathway towards a low-carbon electricity system and assert that they are cleaner, safer and more economically sustainable than nuclear.
In an attempt to negotiate these contending positions, a frequent mantra is that energy strategies should “do everything” in order to address the climate emergency. But – as a number of commentators have noted (for example, here and here) – this would actually be a highly irrational course of action.
Where “doing everything” involves making investments that are slower […]
As a huge winter storm knocked out power for millions of people in Texas, a group representing the coal industry saw an opportunity. “Houston, we have a problem,” the organization Friends of Coal wrote on Facebook. “Coal is the solution.” Another post showed a solar panel covered in snow. “You are warm today because of a coal miner and a pipeline,” it read.
The posts are part of a torrent of conservative statements blaming renewable energy failures for the Texas blackouts. And though such attacks can be easily debunked (the main source of the energy shortfall is natural gas) they serve a larger political purpose: rally a political base that can take back Congress from the Democrats in next year’s midterm elections.
“Everyone must help all across America within the industry,” the coal publication Coal Zoom wrote earlier this year. “The majority of the House must be won back in 2022.”News
The U.S. coal industry is in financial freefall due to competition from natural gas and renewables, as well as the economic shock […]
How researchers classify and quantify causes of death across a population has evolved in recent decades. In addition to long-recognized physiological causes such as heart attack and cancer, the role of behavioral factors—including smoking, dietary patterns and inactivity—began to be quantified in the 1990s.
More recent research has begun to look at the contribution of social factors to U.S. mortality. In the first comprehensive analysis of such studies, researchers at Columbia University’s Mailman School of Public Health found that poverty, low levels of education, poor social support and other social factors contribute about as many deaths in the U.S. as such familiar causes as heart attacks, strokes and lung cancer.
The full study findings are published online ahead of print in the American Journal of Public Health.
The research team, led by Sandro Galea, MD, DrPH, chair of Epidemiology, estimated the number of U.S. deaths attributable to social factors using a systematic review of the available literature combined with vital statistics data. They conducted a MEDLINE search for all English-language articles […]
A little over two years after Israel-based start-up Aleph Farms unveiled the world’s first lab-grown steak, the company has now revealed a much more complex, thick-cut rib-eye steak. Cultivated using a novel 3D bioprinting technology, the company suggests it now has the ability to produce lab-grown iterations of any type of steak.
Lab-grown meat, also known as cultured meat or clean meat, has been rapidly evolving over the past few years. Across a decade scientists moved from producing a “soggy form of pork” in a laboratory to cultured chicken nuggets hitting Singapore market shelves in a world-first regulatory approval. One of the bigger challenges scientists face in creating slaughter-free meat products is replicating the numerous cuts of meat consumers are used to eating.
In 2018 Aleph Farms revealed the world’s first lab-grown steak imitating the cellular structures of a thin minute steak. Now, the company has revealed the creation of a more complex, thick rib-eye steak produced using a new 3D bioprinting technology.
“Unlike 3D printing technology, our 3D bioprinting technology […]
