Every few seconds, our eyelids automatically shutter and our eyeballs roll back in their sockets. So why doesn't blinking plunge us into intermittent darkness and light? New research shows that the brain works extra hard to stabilize our vision despite our fluttering eyes.
As cells age and stop dividing, their fat content changes, along with the way they produce and break down fat and other molecules classified as lipids. By providing broad insights into the connection between lipids and cellular aging, the findings open the door for additional research that could support the development of lipid-based approaches to preventing cell death or hastening it in cancerous tumors.
Researchers have written computer programs that found patterns among anonymized data about web traffic and used those patterns to identify individual users. The researchers note web users with active social media are vulnerable to the attack.
For the first time, scientists have found that non-invasive brain stimulation can be used like a scalpel to affect a specific improvement in precise memory. Precise memory, rather than general memory, is critical for knowing the building you are looking for has a specific color, shape and location, rather than simply knowing the part of town it's in. Precise memory is crucial for normal functioning, and it is often lost in people with memory disorders.
Scientists have developed inexpensive, oxidized carbon particles that extract radioactive metals from water. They said their materials may help purify contaminated waters stored after the Fukushima nuclear power plant accident.
Researchers have identified a genetic promoter of cancer that drives a major form of lung cancer. In a new paper, researchers provide genetic evidence that Ect2 drives lung adenocarcinoma tumor formation.
Next-generation 5G mobile internet technology marks the beginning of the "fourth industrial revolution," the chief executive of Turkey's leading telecoms player told CNBC on Thursday. From a report: 5G is viewed as a technology that can support the developing Internet of Things (IOT) market, which refers to millions -- or potentially billions -- of internet-connected devices that are expected soon to come on to the market. Kaan Terzioglu, the chief executive of Turkcell, which has a market capitalization of $23 billion, touted the potential of the technology, saying that while 4G revolutionized the consumer market, 5G could transform the industrial space. "I think this is the beginning of the fourth generation of the industrial revolution. This will be the platform linking billions of devices together," Terzioglu told CNBC at the World Economic Forum in Davos. Turkcell has been working on 5G technologies since 2013 and this week completed a test in partnership with Ericsson, using the next-generation internet.
Students at elite colleges are even richer than experts realized, according to a new study based on millions of anonymous tax filings and tuition records. At 38 colleges in America, including five in the Ivy League -- Dartmouth, Princeton, Yale, Penn and Brown -- more students came from the top 1 percent of the income scale than from the entire bottom 60 percent. From a report on the NYTimes (alternate non-paywall link): Roughly one in four of the richest students attend an elite college -- universities that typically cluster toward the top of annual rankings (you can find more on our definition of "elite" at the bottom). In contrast, less than one-half of 1 percent of children from the bottom fifth of American families attend an elite college; less than half attend any college at all. Colleges often promote their role in helping poorer students rise in life, and their commitments to affordability. But some elite colleges have focused more on being affordable to low-income families than on expanding access. "Free tuition only helps if you can get in," said Danny Yagan, an assistant professor of economics at the University of California, Berkeley, and one of the authors of the study.
Ants can get their bearings whatever the orientation of their body, new research shows. Their brains may be smaller than the head of a pin, but ants are excellent navigators that use celestial and terrestrial cues to memorize their paths. To do so, they use several regions of the brain simultaneously, proving once again that the brain of insects is more complex than thought.
ProtonMail now has a home on the dark web. The encrypted email provider announced Thursday it will allow its users to access the site through the Tor anonymity service. From a report: Swiss-based PGP end-to-end encrypted email provider, ProtonMail, now has an onion address, allowing users to access its service via a direct connection to the Tor anonymizing network -- in what it describes as an active measure aimed at defending against state-sponsored censorship. The startup, which has amassed more than two million users for its e2e encrypted email service so far, launching out of beta just over a year ago, says it's worried about an increased risk of state-level blocking of pro-privacy tools -- pointing to recent moves such as encryption messaging app Signal being blocked in Egypt, and the UK passing expansive surveillance legislation that mandates tracking of web activity and can also require companies to eschew e2e encryption and backdoor products. The service also saw a bump in sign ups after the election of Donald Trump as US president, last fall -- with web users apparently seeking a non-US based secure email provider in light of the incoming commander-in-chief's expansive digital surveillance powers.
The type of sugar you eat—and not just calorie count—may determine your risk for chronic disease. A new study is the first of its kind to compare the effects of two types of sugar on metabolic and vascular function.
While some scientists believe that the world can achieve significant dematerialization through improvements in technology, a new study finds that technological advances alone will not bring about dematerialization and, ultimately, a sustainable world. The researchers found that no matter how much more efficient and compact a product is made, consumers will only demand more of that product and in the long run increase the total amount of materials used in making that product.
Researchers have found that major flooding and large amounts of precipitation occur on 500-year cycles in central China. These findings shed light on the forecasting of future floods and improve understanding of climate change over time and the potential mechanism of strong precipitation in monsoon regions.
