Princeton Engineering researchers have developed the first perovskite solar cell with a 30-year lifespan. The new device is the first of its kind to rival the performance of silicon-based solar cells. A pioneering new test method will help industry develop consumer-friendly products.
The decline of global poverty is one of the most important achievements in history, but the end of poverty is still very far away.
The consequences of nuclear war would be devastating. Much more should – and can – be done to reduce the risk that humanity will ever fight such a war
Today, ESA’s Gaia mission releases its new treasure trove of data about our home galaxy. Astronomers describe strange ‘starquakes’, stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date.
Guest Post: Insights and lessons from Tonga in the last five weeks.
New research shows how high consumption of sugar affects learning, memory.
Note : I keep getting questions that cause me to realize I should explain something else, or that I explained something poorly. Click here for a list of recent changes. Last modified 2015 Mar 05 16:00 UTC. Here's the original story about this object .
University of Liège researchers discover a new planetary system around a particularly small and cool star.
A team mapping radio waves in the Universe has discovered something unusual that releases a giant burst of energy three times an hour, and it’s unlike anything astronomers have seen before. The team who discovered it think it could be a neutron star or a white dwarf—collapsed cores of stars—with an ultra-powerful…
Many countries ship plastic waste overseas. How much of the world’s waste is traded, and how big is its role in the pollution of our oceans?
Researchers at TNO have been the first to develop a method that will require 200 times less iridium for electrolysis.
A new woody composite engineered by an MIT team is tough as bone and hard as aluminum, and might pave way for naturally derived plastics.
New research in mice shows T cells prevent damaged nerve cells from regenerating due to a reversible, ageing-related mechanism.
Discovery made possible by more than 60 million worms and state-of-the-art imaging accessible only at OHSU, two other national cryoEM centers in the U.S.
A gene called FMNL2 may explain why people with hypertension, diabetes, heart disease, or obesity have a greater risk of developing Alzheimer's disease.
A new study led by UCLA Health scientists shows highly creative people’s brains appear to work differently from others;, with an atypical approach that makes distant connections more quickly by bypassing the “hubs” seen in non-creative brains.
Oxidation radically alters everything we perceive in food. It changes the flavor, aroma, color, and texture of everything we eat and drink. Without oxidation, tea would taste unbearably bitter. Oxidation is what unlocks tea’s hidden flavors by removing bitter compounds and transforming flavorless proteins into…
Engineers infuse a hydrogel structure with a metal solution and then use heat and chemical reactions to leave only the metal behind.
New research suggests environmental changes caused the first mass extinction event in history, which occurred millions of years earlier than scientists previously realized.
How to Identify and Misidentify a Brown Recluse Spider by Rick Vetter Staff Research Associate, UC Riverside Dept. of Entomology
MIT physicsts identified new multilayered configurations of graphene that can be twisted and stacked to elicit robust superconductivity at low temperatures. The study establishes these configurations as the first known “family” of multilayer magic-angle superconductors.
Haleakalā and Maunakea, Hawai ʻ i – For the very first time, astronomers have imaged in real time the dramatic end to a red supergiant’s life, watching the massive star’s rapid self-destruction and final death throes before it collapsed into a Type II supernova.
Penn State scientists have created flexible thermoelectric devices that can wrap around pipes and other hot surfaces, converting wasted heat into electricity more efficiently than previously possible.
