The new Mars landing approach: How we"ll land large payloads on the Red Planet
Back in 2007, I talked with Rob Manning, engineer extraordinaire at the Jet Propulsion Laboratory, and he told me something shocking. Even though he had successfully led the entry, descent, and landing (EDL) teams for three Mars rover missions, he sa.....»»
Why school police officers may not be the most effective way to prevent violence
In 1975, only 1% of public schools had their own police officers. Today, 44% do. A large reason for the increase is the Violent Crime Control and Law Enforcement Act of 1994, which led to the creation of the federal Community Oriented Policing Servic.....»»
Statistical approach improves models of atmosphere on early Earth and exoplanets
As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, developed by a team led.....»»
With new imaging approach, scientists closely analyze microbial adhesive interactions
Scientists have identified many types of bacteria in the mouth, but many problems remain in understanding how they work with one another. One of the problems is that microbes assemble themselves into densely packed multi-species biofilms. Their densi.....»»
Mars Curiosity rover takes a last look at mysterious sulfur
NASA's Curiosity rover is preparing for the next leg of its journey, a months-long trek to a formation called the boxwork, a set of weblike patterns on Mars's surface that stretches for miles. It will soon leave behind Gediz Vallis channel, an area w.....»»
From using plant rinds to high-tech materials, bike helmets have improved significantly over the past two centuries
Imagine—it's the mid-1800s, and you're riding your high-wheeled, penny-farthing bicycle down a dusty road. Sure, it may have some bumps, but if you lose your balance, you're landing on a relatively soft dirt road. But as the years go by, these road.....»»

First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago
Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a volcanic crater. These biomolecules, which came to be known as naphthocyclinones, are representative of a family of antibiotics w.....»»
Volcanic caves research advances the search for life on Mars
Through the intricate study of lava tubes—caves formed following volcanic eruptions when lava cools down—an international team of researchers has uncovered clues about Earth's ancient environments that could be significant in the search for life.....»»
Ensuring water for energy and food production in the Andes-Amazon headwaters
A new study, focused on a remote region of the Peruvian Andes where the waters of the Amazon originate, carries lessons for hydropower operators and farming communities worldwide: collaborating on sustainable land management is the best decision they.....»»
A new way to detect daisy worlds
The daisy world model describes a hypothetical planet that self-regulates, maintaining a delicate balance involving its biogeochemical cycles, climate, and feedback loops that keep it habitable. It's associated with the Gaia Hypothesis developed by J.....»»

Saturday Citations: Cold dark matter takes a hit; a new paradigm for biology; those fracking earthquakes
This week, researchers formulated a new method to calculate the probability of generating intelligent life in the universe. Investigations of a meteorite that originated on Mars revealed that it once interacted with liquid water. And an analysis of f.....»»
Extreme heat weakens land"s power to absorb carbon, analysis finds
A new European Space Agency-backed study shows that the extreme heat waves of 2023, which fueled huge wildfires and severe droughts, also undermined the land's capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric ca.....»»
