Yale Develops a New Tool in the War Against Dust

Inspired by gecko feet, Yale researchers have developed a promising tool in the war on dust. Micrometric and sub-micrometric contaminant particles — what most of us call “dust” — can cause big problems for art conservators, the electronics industry, aerospace engineers, and others. These nanoparticles can prevent a cellphone from working or rob the vitality […]

New Research Traces the Impact of Volcanic Activity on Climate Change

A newly published study shows that for the majority of Earth’s history, continental arc volcanism has been the main driver of long-term climate variability. A geology-based analysis of Earth’s climate history over the past 700 million years provides evidence that climate change has occurred traditionally through slow shifts in the release of carbon dioxide — […]

Zipf's Law from Scale-Free Geometry

Abstract: The spatial distribution of people exhibits clustering across a wide range of scales, from household (∼10−2 km) to continental (∼104 km) scales. Empirical data indicates simple power-law scalings for the size distribution of cities (known as Zipf’s law) and the population density fluctuations as a function of scale. Using techniques from random field theory […]

Children of Older Mothers Do Better

New research shows that the benefits associated with being born in a later year outweigh the biological risks associated with being born to an older mother. Children of older mothers are healthier, taller and obtain more education than the children of younger mothers. The reason is that in industrialized countries educational opportunities are increasing, and […]

New Study Links Genes to Marijuana Dependence and Major Depression

A newly published genome-wide analysis of more than 14,000 individuals has identified several gene variants that increase risk of cannabis dependence. The analysis also suggests that the genetic risk for dependence on marijuana is associated with a higher inherited risk of major depression. The new study is published in the journal JAMA Psychiatry. The study […]

Tiny Plankton May Have a Big Effect on the Ocean’s Carbon Storage

New research from MIT and Bristol University reveal that microscopic, mixotrophic organisms may have a large impact on the ocean’s food web and the global carbon cycle. How do you find your food? Most animal species, whether they rummage through a refrigerator or stalk prey in the wild, obtain nutrients by consuming living organisms. Plants, […]

Scientists Propose a New Method to Probe the Beginning of the Universe

New research from the Harvard-Smithsonian Center for Astrophysics suggests that oscillating heavy particles generated “clocks” in the primordial universe that could be used to determine what produced the initial conditions that gave rise to the universe. How did the universe begin? And what came before the Big Bang? Cosmologists have asked these questions ever since […]

New Graphene Oxide Paper Changes with Strain

New research from Rice University reveals that graphene oxide layers deform evenly under gentle strain and that the mechanical properties of the material change depending on the rate of strain. The same slip-and-stick mechanism that leads to earthquakes is at work on the molecular level in nanoscale materials, where it determines the shear plasticity of […]

Switchable Material Could Enable New Memory Chip Design

A new thin-film material whose phase and electrical properties can be switched between metallic and semiconducting could lead to new memory chip designs. Two MIT researchers have developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its […]

Scientists Identify Protein That Allows Brain Cells to Dampen Their Sensitivity

In a newly published study, neuroscientists from MIT identify a protein that allows brain cells to dampen their sensitivity. Strengthening and weakening the connections between neurons, known as synapses, is vital to the brain’s development and everyday function. One way that neurons weaken their synapses is by swallowing up receptors on their surfaces that normally […]

New Device Harnesses the Energy of Small Bending Motions

Using a new method based on electrochemical principles, engineers at MIT have developed a new device that could provide electrical power source from walking and other ambient motions. For many applications such as biomedical, mechanical, or environmental monitoring devices, harnessing the energy of small motions could provide a small but virtually unlimited power supply. While […]

LRO Reveals Apollo 16 Booster Rocket Impact Site

NASA’s Lunar Reconnaissance Orbiter views the Apollo 16 S-IVB impact site on the moon. After decades of uncertainty, the Apollo 16 S-IVB impact site on the lunar surface has been identified. S-IVBs were portions of the Saturn V rockets that brought astronauts to the moon. The site was identified in imagery from the high-resolution LROC […]

Geomagnetic Field Intensity is Double the Long-Term Historical Average

New research from MIT shows that the Earth’s geomagnetic field intensity is double the long-term historical average, indicating that the current field intensity has a long way to fall before reaching an unstable level that would lead to a reversal. The intensity of Earth’s geomagnetic field has been dropping for the past 200 years, at […]
