• New way to test antibiotics could lead to better drugs

    MIT and Harvard University researchers have engineered E. coli cells that can be used to study how bacteria at an infection site respond to antibiotic treatment, allowing scientists to learn more about how existing antibiotics work and potentially help them to develop new drugs.

    In the new study, which appears in the Aug. 31 issue of Cell Host and Microbe, the researchers found evidence that some existing hypotheses about how bacteria respond to antibiotics are not correct.

  • NASA Sees Tropical Storm Katia Develop Near Mexico's East Coast

    NASA’s Terra satellite passed over Tropical Storm Katia as it was developing along Mexico’s east coast.  On Sept. 5, the thirteenth tropical depression of the Eastern Pacific Ocean hurricane season formed about 80 miles (125 kph) east of Tampico, Mexico, in the western Gulf of Mexico. 

    The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Terra satellite captured a visible-light image of the depression as it was organizing on Sept. 5 at 1:10 p.m. EDT (1710 UTC). The image showed that deep convection and thunderstorms were forming over the center. By 4 p.m. EDT, the National Hurricane Center noted that the depression had formed.

  • Hurricane Harvey Flooding Seen in New NASA Satellite Image

    On Sept. 5, 2017, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this image of the area around Bay City, Texas, about 50 miles (80 kilometers) southwest of Houston. Hurricane Harvey caused extensive inland flooding, seen as dark blue areas where the water is relatively clear, and green-grey where the water carries sediment. The image covers an area of 32 by 65 miles (52 by 105 kilometers), and is centered at 29.2 degrees north, 95.8 degrees west.

  • NASA Looks at Hurricane Irma's Heat Engine

    On September 5, 2017 at 1 p.m. EDT (1700 UTC) the radar on the Global Precipitation Measuring Mission (GPM) satellite captured a 3-D view of the heat engine inside of category-5 Hurricane Irma. 

    Under the central ring of clouds that circles the eye, water that had evaporated from the ocean surface condenses, releases heat, and powers the circling winds of the hurricane. The radar on the GPM satellite is able to estimate how much water is falling as precipitation inside of the hurricane, which serves as a guide to how much energy is being released inside the hurricane's central "heat engine."

  • Unraveling a Major Cause of Sea Ice Retreat in the Arctic Ocean

    Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.

  • Cloud Formation Suppressed by Biogenic Organic Emissions

    Researchers have found evidence that near-ground biogenic emissions of organics suppress cloud formation in cool-temperate forests in autumn, providing clues to how global warming will affect cloud formation and the overall climate.

  • Why US Battery Startups Fail -- And How to Fix It

    Better batteries are critical to the world’s clean energy future. More economical and efficient batteries would help to solve many of our planet’s energy challenges, paving the way towards long-range electric vehicles to help reduce our reliance on fossil fuels as well as advancing renewable energy production by resolving intermittency problems. However, the scientific research needed to bring the necessary advances in materials to market in the US remains a formidable challenge. Hurdles include high upfront capital costs and long timelines to success – leading many startup companies to fail, even with generous funding from venture capital and esteemed investors such as Bill Gates.
