Scientists propose 3D graphene-like 'hyper-honeycomb' structures(Phys.org)—Scientists have proposed a new family of structures that are three-dimensional (3D) variations of graphene, the simplest example of which is called a "hyper-honeycomb." If the proposed structures can be experimentally realized, the new ways to arrange carbon atoms would add to the ever-growing number of new carbon allotropes. The scientists also predict that, among its interesting properties, the hyper-honeycomb could potentially be even more stable than diamond. | |

It also highlights the potential for other mineral deposits in the same area. | |
Has the green revolution really succeeded?Over the past 50 years, human population has more than doubled, but cereal-crop production has grown even faster. Mechanization, synthetic fertilizers, new high-yield seeds and other advances in intensified agriculture have enabled us not only to keep up, but to actually reduce world hunger, according to a 2014 UN report. 1960s doomsday scenarios of mass starvation have not materialized. Victory may be declared, at least for now–yes? | |
Cool summer of 2013 boosted Arctic sea iceThe volume of Arctic sea ice increased by a third after the summer of 2013 as the unusually cool air temperatures prevented the ice from melting, according to UCL and University of Leeds scientists. This suggests that the ice pack in the Northern hemisphere is more sensitive to changes in summer melting than it is to winter cooling, a finding which will help researchers to predict future changes in its volume. | |

Ocean acidification may cause dramatic changes to phytoplanktonOceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8—significantly lower than any levels seen in open ocean marine communities today. | |

A promising approach to fuel production that would reduce costs, energy use, and carbon dioxide emissionsNew findings released by MIT researchers could help energy companies implement a long-recognized process for converting heavy, high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a change that would reduce costs, energy use, and carbon dioxide emissions. The process involves combining oil with water under such high pressures and temperatures that they mix together, molecule by molecule, and chemically react. The researchers have produced the first detailed picture of the reactions that occur and the role played by the water in breaking apart the heavy oil compounds and shifting the sulfur into easily removable gases. They have also formulated models that show how best to mix the oil and water to promote the desired reactions—critical guidance for the design of commercial-scale reactors. | |

Citizen science for salamanders in Southwest New HampshireEvery spring, as the earth thaws and warm rains drench New England, thousands of amphibians make their way to vernal pools to breed. It's a magical time. For the salamanders and frogs undertaking their annual migration, it's also a dangerous one. One study in western and central Massachusetts found that roadkill rates on even relatively quiet roads could lead to extirpation of local spotted salamander populations in as few as 25 years. Another study reported that 50-100% of salamanders attempting to cross a paved rural road in upstate New York didn't survive the trek. | |
Baboons follow the majorityBaboons live together in hierarchical groups. However, important decisions are not dictated by the highest-ranking group members but are instead made democratically. This was discovered by a team of scientists including Iain Couzin from the Max Planck Institute for Ornithology in Radolfzell. The researchers monitored the movements of a baboon community using GPS devices with to-the-second precision. This enabled them to observe how the animals make decisions and the direction in which the group moves. The process is triggered by individuals who propose a direction. If opinions are divided, the undecided baboons follow the majority. This process is entirely democratic and takes place irrespective of which direction the dominant animals have chosen. | |
Rejuvenating the comparative approach in modern neuroscience65 years ago, the famed behavioral endocrinologist Frank Beach wrote an article in The American Psychologist entitled 'The Snark was a Boojum'.

Expansion of golden jackal across Europe creates tricky legal issuesFor a long time jackals have been known to most Europeans only through documentaries on African wildlife. But one species – the golden jackal (canis aureus) – is now advancing northward and westward across Europe from its traditional range along the Mediterranean and Black Sea coasts as far as Switzerland and Estonia. This has resulted in considerable confusion – should jackals be protected as a native species everywhere in Europe? Yes, says legal scholar Arie Trouwborst of Tilburg University. | |
Fungi—key to tree survival in warming forestMuch like healthy bacteria in one's gut supports health of the human body, fungus in soil can be integral to survival of trees.

Simple but elusive – why are we still talking about HIV drug delivery?My main memory of the last IAS conference I attended, held in Vienna in 2010, was a resounding standing ovation for a presentation (including this video) by one of my colleagues working in Mozambique. In a situation where antiretroviral therapy (ART) had not been extensively decentralised, and where drug supply limitations meant people had to attend a clinic every month to pick up their drugs, a simple idea had transformed the way that patients received their HIV care. In short, people living near each other had got together and agreed to take it in turns to pick up each other's drugs. This resulted in less time spent at the clinic and lower transport costs for patients and an immediate reduction in workload for clinic staff. | |
The case for unlimited tablet time for toddlersThis sounds extreme, but first let me ask: how many parents do you think actually keep track of their kids' screen time?
