Energy-efficient accelerator was 50 years in the making

With the introduction of CBETA, the Cornell-Brookhaven ERL Test Accelerator, Cornell University and Brookhaven National Laboratory scientists are following up on the concept of energy-recovering particle accelerators first introduced by physicist Maury Tigner at Cornell more than 50 years ago.

CBETA tests two energy-saving technologies for accelerators: energy recovery and permanent magnets. An energy recovery linac (ERL) like CBETA reclaims the energy of a used electron beam instead of dumping it after the experiment. The recovered energy is used to accelerate the next beam of particles, creating a beam of electrons that can be used for many areas of research. The beams are accelerated by Superconducting Radio Frequency (SRF) units, another energy-efficient technology pioneered at Cornell.

Global Warming May Cause Bees to Mistime Spring Emergence, Missing Their Food Supply

If it’s all in the timing, then climate change may spell problems for bees. Scientists have found that global warming may cause temporal mismatches between bees and the plant species on which they depend for food.

As Seas Rise, Tropical Pacific Islands Face a Perfect Storm

Among the places expected to be most hard-hit by sea level rise in the coming century or two are the islands of the tropical Pacific Ocean, ranging from sparsely developed archipelagos in Micronesia to heavily populated coastal areas on the Hawaiian Islands, such as Honolulu. 

Surveying sea floor animals for offshore renewable energy

There is growing interest in developing offshore wind and wave energy facilities in the Pacific Northwest. But not much is known about the sediment and animal life along the sea floor in the region.

Rising temperatures are curbing ocean's capacity to store carbon

If there is anywhere for carbon dioxide to disappear in large quantities from the atmosphere, it is into the Earth’s oceans. There, huge populations of plankton can soak up carbon dioxide from surface waters and gobble it up as a part of photosynthesis, generating energy for their livelihood. When plankton die, they sink thousands of feet, taking with them the carbon that was once in the atmosphere, and stashing it in the deep ocean.

Pokémon Go Anniversary: Kent State Researcher Study Link Between the Viral Mobile App and a Healthier Lifestyle

Today marks the one year anniversary of Pokémon GO’s worldwide release that sent crowds hiking through parks, meandering into streets and walking for miles in search of Pokémon, those cute little digital characters that appear in real locations on your smartphone.

Hubble Pushed Beyond Limits to Spot Clumps of New Stars in Distant Galaxy

When it comes to the distant universe, even the keen vision of NASA's Hubble Space Telescope can only go so far. Teasing out finer details requires clever thinking and a little help from a cosmic alignment with a gravitational lens.

Working together to reduce infection in extreme weather events

Researchers have called for health professionals and climate forecasters to work more closely together ahead of extreme weather events and gradual climate change to help prevent the spread of infections.

Falling Sea Level caused Volcanos to Overflow

Climate evolution shows some regularities, which can be traced throughout long periods of earth’s history. One of them is that the global average temperature and the carbon dioxide concentration in the atmosphere usually go hand-in-hand. To put it simple: If the temperatures decline, the CO2 values also decrease and vice versa.

NASA Sees Central Atlantic Ocean's Forming Tropical Depression 4

As Tropical Depression 4 was getting organized in the central Atlantic Ocean the Global Precipitation Measurement Mission or GPM satellite peered into the storm and measured rainfall within. The system became Tropical Depression 4 on July 6.
