Seven tips for surviving the apocalypse Billionaires who have made their fortunes in Silicon Valley seem to be worried about the future. So worried in fact, that some of them are reportedly buying vast estates in places such as New Zealand, as "apocalypse insurance".

The sky is the limit for new low-cost 3-D printer Sliperiet at Umeå Arts Campus is in the process of making a 3-D printed Tower of Babel using a novel hanging printer. This offers a low-cost solution and increased flexibility to print large volumes.
Small molecules fighting aging-related diseases For the first time an international research network led by Bayreuth Biochemist Prof. Dr. Clemens Steegborn has succeeded in producing small molecules able to activate the enzyme sirtuin 6. Furthermore, the scientists were able to reveal the structural basis of such processes. These findings will enable the development of drugs that might support the fight against aging-related diseases.
Small nanoparticles have surprisingly big effects on polymer nanocomposites Polymer nanocomposites mix particles billionths of a meter (nanometers, nm) in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer goods. When a team led by the Department of Energy's Oa
New species concept based on mitochondrial & nuclear DNA coadaptation What is a species? Biologists—and ornithologists in particular—have been debating the best definition for a very long time. A new commentary published in The Auk: Ornithological Advances proposes a novel concept: that species can be defined based on the unique coadaptations between their two genomes, one in the nuclei of their cells and the other in their mitochondria.
Stabilizing soils with sulfates to improve their constructional properties The journal Applied Clay Science has recently published the paper 'Sulfate soils stabilization with magnesium-based bindersâ', a piece of research led by Dr Andrés Seco-Meneses on the stabilizing of sulfate soils in which Beñat García-Grancianteparaluceta, lecturer in the UPV/EHU's Department of Mining and Metallurgical Engineering and Materials Science, has collaborated alongside a group of rese
New survey finds 'Peter Pan' radio galaxies that may never grow up A team of astronomers has doubled the number of known young, compact radio galaxies—galaxies powered by newly energized black holes. The improved tally will help astronomers understand the relationship between the size of these radio sources and their age, as well as the nature of the galaxy itself.
Synthesis of medicinally privileged heterocycles through dielectric heating Heterocyclic compounds are enormously crucial in various industries including food, agricultural, cosmetics and pharmaceuticals. Heterocyclic pharmacophores are one of the main chemical components in drug discovery research. A report in 2013 claims that four out of six and nine out of twenty one highest selling medicines in the world are small molecule heterocyclic compounds. Therefore, easy acces
Researchers propose technique for measuring weak or nonexistent magnetic fields Physicists at the University of Iowa have proposed a new technique to detect and measure materials that give off weak magnetic signals or have no magnetic field at all. Their solution would use a noninvasive probe to induce a magnetic response in the material being studied and then detect how that response changes the probe's own magnetic field.
Assistive tech for people with visual impairments to identify scientific images on a computer screen Purdue University researchers are developing software in a "haptic device" that could give people with visual impairments the ability to identify scientific images on a computer screen using their other senses.
Travelling through scattering tissue with far less light Medical applications of light, looking inside human tissue, often are limited by the highly scattering nature of tissue. Inuitively, a lower limit of one photon per camera pixel is assumed. Scientists of the University of Twente in The Netherlands and Caltech in Pasadena, USA, prove that the lower limit is actually much lower, thus opening possibilities of going deeper into tissue with less light.
A new tool for genetically engineering the oldest branch of life A new study by G. William Arends Professor of Microbiology at the University of Illinois Bill Metcalf with postdoctoral Fellow Dipti Nayak has documented the use of CRISPR-Cas9 mediated genome editing in the third domain of life, Archaea, for the first time. Their groundbreaking work, reported in Proceedings of the National Academy of Sciences, has the potential to vastly accelerate future studies
Developing tools for reproducibility The concept of reproducibility is vital when it comes to research, as it provides transparency and ensures clarity for findings. However, reproducibility is often difficult because investigators publish only their papers and not the data or other important aspects that support their results. Now, Notre Dame researchers at the Center for Research Computing (CRC) are developing several tools that ca

Uncovering new relationships and organizational principles in protein interaction networks Proteins, those basic components of cells and tissues, carry out many biological functions by working with partners in networks. The dynamic nature of these networks – where proteins interact with different partners at different times and in different cellular environments – can present a challenge to scientists who study them. However, researchers at the Stowers Institute for Medical Research hav
How vision may have driven fishes onto land About 375 million years ago, certain fishes had developed powerfully strong paired fins that were capable of transporting them out of the water and onto land.
Warped meteor showers hit Earth at all angles Some meteor showers persist for weeks and months, even though Earth sweeps a big arc around the Sun during that time. The meteors arrive from a slightly different direction each day, which is a clue to why these showers last so long. In a review of ongoing meteor surveillance projects worldwide, 45 showers are identified that take this motion to extremes, visualized in spectacular animation.
Share of women researchers grows, research as impactful as men's The share of women among researchers has increased between four and 11 percentage points between the periods 1996-2000 and 2011-2015 among 12 geographies. Across these geographies, women's scholarly articles are cited or downloaded at similar rates to men's while women tend to publish fewer articles than men on average. These are two of the key findings presented in a new global study released tod

How exercise — interval training in particular — helps your mitochondria stave off old age Researchers have long suspected that the benefits of exercise extend down to the cellular level, but know relatively little about which exercises help cells rebuild key organelles that deteriorate with aging. A new study found that exercise — and in particular high-intensity interval training in aerobic exercises such as biking and walking — caused cells to make more proteins for their energy-pr

Ancient stardust sheds light on the first stars Astronomers have used ALMA to detect a huge mass of glowing stardust in a galaxy seen when the Universe was only four percent of its present age. This galaxy was observed shortly after its formation and is the most distant galaxy in which dust has been detected. This observation is also the most distant detection of oxygen in the Universe. These new results provide brand-new insights into the birt
Violent video games found not to affect empathy The link between playing violent video games and antisocial behavior, such as increased aggression and decreased empathy, is hotly debated. In a recent study the long-term effects of playing violent video games were investigated. This study found that empathy is not blunted by playing such games long-term.
