Longer, stronger summers in the Gulf of Maine

Summer is coming to the Gulf of Maine, longer and warmer than ever — as much as two months longer. That’s the message of a new research article by a team of scientists led by Andrew Thomas of the University of Maine School of Marine Sciences. The study, published in the journal Elementa, examined the seasonality of sea surface temperature trends along the northeast coast of the United States.

For all but a small region immediately north of Cape Hatteras at the southern edge of their study area, the researchers confirmed that surface water temperatures have an increasing trend over the last three decades, with the Gulf of Maine warming at about 0.4 degrees Celsius per decade. The new analysis both mapped the geographic pattern of these trends and showed that the increase is actually much stronger than this in the summer and early fall months, from June to October, and weaker in the winter months.

Stanford professor tests a cooling system that works without electricity

It looks like a regular roof, but the top of the Packard Electrical Engineering Building at Stanford University has been the setting of many milestones in the development of an innovative cooling technology that could someday be part of our everyday lives. Since 2013, Shanhui Fan, professor of electrical engineering, and his students and research associates have employed this roof as a testbed for a high-tech mirror-like optical surface that could be the future of lower-energy air conditioning and refrigeration.

URI researcher says invasive plants change ecosystems from the bottom up

In a common garden at the University of Rhode Island, Laura Meyerson has been growing specimens of Phragmites – also known as the common reed – that she has collected from around the world. And while they are all the same species, each plant lineage exhibits unique traits.

Now Meyerson, a professor of natural resources sciences, and Northeastern University Professor Jennifer Bowen have revealed that even when two different lineages grow side-by-side in the same ecosystem, the bacterial communities in the soil differ dramatically. It’s a discovery that will aid in understanding how plant invasions succeed and the conditions necessary for their success.

'Extreme' Telescopes Find the Second-fastest-spinning Pulsar

By following up on mysterious high-energy sources mapped out by NASA's Fermi Gamma-ray Space Telescope, the Netherlands-based Low Frequency Array (LOFAR) radio telescope has identified a pulsar spinning at more than 42,000 revolutions per minute, making it the second-fastest known.

Warmer World May Bring More Local, Less Global, Temperature Variability

Many tropical or subtropical regions could see sharp increases in natural temperature variability as Earth’s climate warms over coming decades, a new Duke University-led study suggests.

Eat Fat, Live Longer?

As more people live into their 80s and 90s, researchers have delved into the issues of health and quality of life during aging. A recent mouse study at the UC Davis School of Veterinary Medicine sheds light on those questions by demonstrating that a high-fat, or ketogenic, diet not only increases longevity, but improves physical strength.

When strangers can control our lights

Smart home products such as lamps controlled via mobile devices are becoming ever more popular in private households. We would, however, feel vulnerable in our own four walls if strangers suddenly started switching the lights in our homes on and off. Researchers at the IT Security Infrastructures group, FAU have discovered security problems of this nature in smart lights manufactured by GE, IKEA, Philips and Osram.

Medical camera sees through the body

Scientists have developed a camera that can see through the human body.

The camera is designed to help doctors track medical tools known as endoscopes that are used to investigate a range of internal conditions.

Scientists developed "smart fertilizer"

According to the head of the works Tatiana Volova, Professor of SibFU and the Head of Laboratory in the Institute of Biophysics KSC of SB RAS, development of a new generation of drugs with the use of bio-decomposable materials which decompose under the influence of the microflora to innocuous products and provide a gradual release of the active principle into the soil, is the newest area of research in the field of agriculture. For example, nitrogen is one of the elements, which is often lacking for the growth and development of plants. Plant-available nitrogen in the soil is usually small. Moreover, its compounds are chemically very mobile and easily leached from the soil. In this connection there is the task of developing such forms of nitrogen fertilizers that provide slow release nitrogen and the constancy of its concentration in the soil.

Taking a deep breath?

The Labrador Sea in the North Atlantic is one of the few areas in the world ocean where cold, saline seawater sinks to large depths and forms deep water. This convection process also transports oxygen into the deep sea. A team of scientists from Scripps Institution of Oceanography (San Diego, California), Dalhousie University (Halifax, Canada) and GEOMAR Helmholtz Centre for Ocean Research Kiel have now published the analysis of data obtained from the mooring K1 in the international scientific journal Geophysical Research Letters. The results show that in winter 2014/2015 an unusually high amount of oxygen was absorbed by the ocean in the region. The actual oxygen uptake at the sea surface is very difficult to determine directly, but the scientists were able to derive the oxygen uptake from the oxygen content measured throughout the water column. One of the questions the scientists were concerned with: Can the strong oxygen uptake in the Labrador Sea compensate the global oxygen loss of the ocean?
