Aluminum is the most abundant metal on Earth and used in everything from cars and airplanes to the foil used to wrap Thanksgiving leftovers. But there was a time when it was more valuable than gold.
Much more appetizing than a pile of plain tomatoes on a plate. (Ilana E. Strauss/) You're having a party, and you realize you've run out of side dishes. You open the fridge. To your horror, you see only a few tomatoes. You're hungry now, and so are your friends, but you don't want to chomp down on plain plants like a goat. No, we humans are civilized, and we like our food not just calorie-rich, b

We're seeing this occur more and more flagrantly where corporations defer to a "news media" company for evidence countering wrong-doing. Corporation A publishes press release denying allegations. Shill media company B spins the press release making it a positive thing for company A. Shill media company B's content is rehosted through several other blogspam sites to gain traction. It's also linked
Over the holiday period the Guardian's leader column examines the challenges of the future by fathoming out the present. Today we look at the struggle for the soul of Christianity "There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus." These words , written by Saint Paul 2,000 years ago, are central to the Christian faith
Are they really suffering? The New York Times this week highlighted a paper looking at academic work habits, Working 9 to 5, not the way to make an academic living: observational analysis of manuscript and peer review , by Barnett, Mewter and Schroter. It won't come as a surprise to anybody with a researcher available for observation to see suspicions confirmed: scientists are "on" year 'round, l
This is a re-post from The Conversation by Mark Maslin , Professor of Earth System Science, UCL The fossil fuel industry, political lobbyists, media moguls and individuals have spent the past 30 years sowing doubt about the reality of climate change – where none exists. The latest estimate is that the world's five largest publicly-owned oil and gas companies spend about US$200 million a year on l
When my mother went into labor on December 24, 23 years ago, she begged the doctor to deliver me before midnight. A December baby herself, she knew that being born during the holiday season was difficult, and wanted to spare me from being born on an actual holiday. She also wanted to get the labor over with, as she tells it, so she could rush home to prepare Christmas dinner for all of the cousin
"I [have] had lots of troubles; so I write jolly tales," Louisa May Alcott once quipped of her career. This blithe, self-effacing remark, tinged with melancholy, is the opening epigraph for Greta Gerwig's new adaptation of Alcott's mightiest novel, Little Women —and it's a perfect summation of the sharp but wistful tone that defined Alcott's work. Gerwig captures that mood with this film, a spark

Number eight on Big Think's list this year says the future will not even look like wars to the traditional mind. The worst threat is systemic. It's growing entropy in the global system. Today, when Russia wants to shake up Europe — the world — its operatives weaponize refugees. That is, by bombing civilian centers, they create an avalanche of refugees, which, in turn, creates Brexit and the rise
Santa and his reindeer didn't appear in the sky immediately upon the birth of Christ, and the Christmas holiday as Americans now know it—the carols, the lights, the long-distance travel, and, above all, the massive consumer spending on gifts—didn't always exist this way. By the mid-1800s, the holiday had picked up and assimilated various elements of European religious and pagan traditions. Upon t
In the past few months, protesters in Hong Kong have engaged in a citywide strike. In Lebanon , mass protests led to the prime minister's resignation. In India, nationwide protests have defied government restrictions on public gatherings. Meanwhile, protesters in other parts of the world remain forcibly subdued—such as in Chinese "reeducation" camps and Saudi prisons. These examples, reflecting a
PLUS. Glem den primitive, abelignende vildmand. Ny forskning viser, at neandertalerne slet ikke var så forskellige fra os. De udnyttede lægeplanter, fremstillede lim og ville ikke skille sig meget ud fra mængden i dag.
Leith Anderson is one of the most influential evangelical leaders in America, and yet he has been all but silent about President Donald Trump's reshaping of American evangelicalism. Anderson has held basically every prominent job available to Christian pastors— leading an influential megachurch , teaching, writing books, serving in an advisory role in the Obama administration. Above all, he is an
Artificial wombs could radically change the physical, social, and emotional costs of pregnancy. But the technology doesn't address the patriarchal values that still dehumanize the value of the maternal-fetal relationship — something that could be perpetuated by artificial wombs themselves.
PLUS. Forestil dig, at du hænger ud på en bar, og pludselig træder en neandertaler ind ad døren. En abelignende mand med en kølle, ikk'? Nej, lyder det fra forskerne. De ikke bare ligner os. De er os.
An international joint research team led by NIMS succeeded in fabricating a neuromorphic network composed of numerous metallic nanowires. Using this network, the team was able to generate electrical characteristics similar to those associated with higher order brain functions unique to humans, such as memorization, learning, forgetting, becoming alert and returning to calm. The team then clarified

In PNAS, Ram et al. (1) present an approach to decipher competition in mixed cultures of biotechnological interest. The approach—devoted to those cases in which competitive behavior depends on cellular densities—is intended to characterize mixed-culture individual dynamics by fitting the mixed-culture optical density (OD) data to a nonlinear competition Lotka–Volterra…
We are glad to see interest in our computational approach for predicting microbial growth in a mixed culture from growth curve data (1). Balsa-Canto et al. (2) provide experimental and numerical results to conclude that growth curve data are insufficient to predict the dynamics in mixed cultures. We believe that…
In Cudini et al. (1), the authors suggest that earlier work has argued high levels of intrahost variation in human cytomegalovirus (HCMV) to be the result of exceptionally fast mutation rates (on par with RNA viruses), citing our recent review (2) as evidence. In reality, ref. 2 noted that levels…
Jensen and Kowalik (1) have reported that intrahost variation in human cytomegalovirus (HCMV) approaches levels similar to those of hepatitis C virus, with fast mutation rates mooted as one explanation (2). While we discuss that HCMV mutation rates were postulated as an explanation for high diversity, the focus of our…
Vascular plants provide most of the biomass, food, and feed on earth, yet the molecular innovations that led to the evolution of their conductive tissues are unknown. Here, we reveal the evolutionary trajectory for the heterodimeric TMO5/LHW transcription factor complex, which is rate-limiting for vascular cell proliferation in Arabidopsis thaliana….
The El Niño Southern Oscillation (ENSO) is one of the most prominent interannual climate phenomena. Early and reliable ENSO forecasting remains a crucial goal, due to its serious implications for economy, society, and ecosystem. Despite the development of various dynamical and statistical prediction models in the recent decades, the "spring…
The protracted development of structural and functional brain connectivity within distributed association networks coincides with improvements in higher-order cognitive processes such as executive function. However, it remains unclear how white-matter architecture develops during youth to directly support coordinated neural activity. Here, we characterize the development of structure–function coup
