Bots appear to behave differently in culturally distinct online environments. A new paper says the findings are a warning to those using artificial intelligence for building autonomous vehicles, cyber security systems or for managing social media.
Wayne Williams, writing for BetaNews: A new study finds that tech reporting is generally more pessimistic now than in the past, and for two very different reasons. The new report from the Information Technology and Innovation Foundation (ITIF), and based on textual analysis of 250 articles from The New York Times, The Wall Street Journal, and The Washington Post from 1986 to 2013, highlights how the tone of tech reporting has shifted in the past 20 years. In general, the ITIF found that in the 1980s and 1990s, coverage of technology was largely positive, but this changed from the mid-1990s to 2013, when more negative reports covering the downside of technology, its failure to live up to its promises, and potential ill effects, started to appear. The ITIF attributes this shift to two main causes, the first being that "there has been a significant increase in the number of civil-society organizations and attention-seeking scholars focused on painting a threatening picture of technology," and second, and perhaps most pertinent, "news organizations are under increased financial pressure, and as a result, reporters may have less time and fewer resources to dig deep into technology issues."
How can the same infection result in dramatically different levels of illness in two different people? A new study identifies two conditions -- a genetic immunodeficiency and delayed acquired immunity -- that explain why a patient developed a life-threatening disease in response to a common strain of bacterium.
Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study.
Much has been made in popular culture about millennials as they join the working world, including their tendency to job hop. Although this behavior often is explained as a loyalty issue, new research reveals one reason young workers choose to leave a firm is because they find a disconnect between their beliefs and the culture they observe in the workplace.
Reader AmiMoJo writes: In comments submitted to a U.S. Copyright Office consultation, Google has given the DMCA a vote of support, despite widespread abuse. Noting that the law allows for innovation and agreements with content creators, Google says that 99.95% of URLs it was asked to take down last month didn't even exist in its search indexes. "For example, in January 2017, the most prolific submitter submitted notices that Google honored for 16,457,433 URLs. But on further inspection, 16,450,129 (99.97%) of those URLs were not in our search index in the first place."
Reader Artem Tashkinov writes: Ten years after of SHA-1 was first introduced, Google has announced the first practical technique for generating an SHA-1 collision. It required two years of research between the CWI Institute in Amsterdam and Google. As a proof of the attack, Google has released two PDF files that have identical SHA-1 hashes but different content. The amount of computations required to carry out the attack is staggering: nine quintillion (9,223,372,036,854,775,808) SHA1 computations in total which took 6,500 years of CPU computation to complete the attack first phase and 110 years of GPU computation to complete the second phase. Google says that people should migrate to newer hashing algorithms like SHA-256 and SHA-3, however it's worth noting that there are currently no ways of finding a collision for both MD5 and SHA-1 hashes simultaneously which means that we still can use old proven hardware accelerated hash functions to be on the safe side.
Soybeans with resistance to soybean cyst nematodes seem to have a yield advantage compared to susceptible varieties when SCN is present. Until now, scientists did not know what level of SCN infestation is needed to achieve the yield advantage. A new study shows that SCN resistance from the soybean accession PI 88788 offers yield advantages even at very low infestation rates.
Contact tracing -- a process of identifying everyone who has come into contact with those infected by a particular disease -- combined with targeted, indoor spraying of insecticide can greatly reduce the spread of the mosquito-borne dengue virus, finds a study.
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an 'enormous Lyman-alpha nebula' (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.
The last Neanderthal died 40,000 years ago, but much of their genome lives on, in bits and pieces, through modern humans. The impact of Neanderthals' genetic contribution has been uncertain. Researchers now report evidence that Neanderthal DNA sequences still influence how genes are turned on or off in modern humans. Neanderthal genes' effects on gene expression likely contribute to traits such as height and susceptibility to schizophrenia or lupus, the researchers found.
Sexual reproduction and viral infections both rely on a functionally identical protein, according to new research. The protein enables the fusion of two cells, such as a sperm cell and egg cell, or the fusion of a virus with a cell membrane. The discovery suggests that the protein evolved early in the history of life on Earth, and new details about the protein's function could help fight parasitic diseases such as malaria.
