Grand Canyon Thought to Be 65 Million Years Older Than Previous Estimates

grand-canyon-arizona-sunset

A new analysis of the mineral grains from the bottom of the Grand Canyon indicates that it was formed about 70 million years ago, during the late Cretaceous Period, a time when dinosaurs roamed the Earth. The scientists published their findings in the journal Science. This new research pushes back the date for the formation […]

Kitti’s Hog-Nosed Bat Is World’s Smallest Mammal

bumblebee-bat

The Kitti’s hog-nosed bat (Craseonycteris thonglongyai), sometimes referred to as the bumblebee bat due to its diminutive size, was discovered in 1970s and could arguably be the world’s smallest mammal, depending on how size is defined. C. thonglongyai is listed as vulnerable by the IUCN and is found in western Thailand and southeast Burma, in […]

As Supersymmetry Fails, Physicists Looking for New Models

LHC-tunnel-SUSY

As the Large Hadron Collider has been unable to find any of the particles suggested by supersymmetry, theoretical particle physicists are trying to change their worldview, away from supersymmetry to theories that could explain the results. So far, there have been no hints beyond the Standard Model of Particle Physics from the LHC. A recent […]

Lines on Crocodiles’ Crania Are Cracks in Skin, Not Scales

crocodylus-niloticus-lines-face

The “scales” on a crocodile’s cranium aren’t really scales, but simple physical cracks rather than developmentally programmed scales that cover the rest of a crocodile’s body. Researchers had previously assumed that the deep lines marked boundaries between scales. The scientists published their findings in the journal Science. Understanding the physical process by which the cracks […]

New Finding Challenges Theories of How Rocky, Earth-Scale Planets Form

finding challenges theories of how rocky, Earth-scale planets form

While viewing the young brown dwarf ISO-Oph 102, an international team of astronomers pinpointed carbon monoxide gas around the brown dwarf and found that the outer region of the dusty disc encircling the brown dwarf contains millimeter-sized solid grains. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time found that the […]

Dryland Farmers Work With Little Water

irrigation-non-viable

A new generation of extremely efficient farmers sees irrigation as a non-viable alternative. These farmers use dryland farming, which has helped farmers to get through the drought and allow their crops to better handle low moisture conditions. In dryland farming, crops are rotated every two years, leaving half of the fields fallow at any given […]

Epidemiologists Trying to Track Down Novel Coronavirus

sars-coronavirus

The new coronavirus, linked to different cases in the Qatar and Saudi Arabia, was named HCoV-EMC, short for human coronavirus and the Erasmus Medical Center in Rotterdam, the Netherlands. The current situation has reminded many of the SARS outbreak of 2003, which spread from China to as far as Toronto and killed 916 people. The […]

Exposomics Looks to Tie Environmental Exposure to Biological Triggers of Disease

eu-expopsomic-studies

European researchers are going to monitor thousands of people by giving them smartphones, which will record the chemicals to which they are exposed to every day. Two projects announced this week that they had won €17.3 million ($22.4 million) from the European Commission to study the exposome, the effects of environmental exposures on health. The […]

A Comprehensive Review on the Ice Melt in Antarctica & Greenland

joughin-polar-iceberg

A new study has come up with the most accurate estimate yet for the melting of the polar ice sheets, possibly ending decades of uncertainty about whether the sheets will melt further or actually gain mass in the face of climate change. The scientists published their findings in the journal Science. The ice sheets in […]

Simulated Brain Performs Well at Simple Tasks

spaun-brain-simulation

The Semantic Pointer Architecture Unified Network (Spaun) was created by theoretical neuroscientists to simulate complex behavior from fewer neurons. The scientists published their findings in the journal Science. Spaun contains 2.5 million simulated neurons, which is a lot fewer than the 86 billion that the average human has, but enough to recognize lists of numbers, […]

Fabric-Covered Blades Could Make Wind Turbines Cheaper & More Efficient

wind fabric

GE’s latest wind technology development is fabric-covered wind turbine blades, which are supposed to even more efficient that the fiberglass that is used now. The swap in technology will allow turbine blades to perform as well, but can be made on-site at a much lower cost, 25-40% less. This drop in manufacturing cost could help […]
