In this digital age, with phones at our finger tips, you would think that access to constant communication would make us feel closer to one another. But a new study by researchers at Kent State University shows that may not be the case. In fact, cell phone use might actually lead to feeling less socially connected, depending on your gender or cell phone habits.

LOS ALAMOS, N.M., August 17, 2016--A new study at Los Alamos National Laboratory and in collaboration with Stanford Synchrotron Radiation Lightsource greatly improves scientists' understanding of the element actinium. The insights could support innovation in creating new classes of anticancer drugs.

Tropical Depression 6 developed in the far eastern North Atlantic Ocean and NASA and NOAA satellites provided infrared and visible views at the storm.

RIVERSIDE, Calif. (http://www.ucr.edu) -- In a new paper, University of California, Riverside theoretical physicist Flip Tanedo and his collaborators have made new progress towards unravelling a mystery in the beryllium nucleus that may be evidence for a fifth force of nature.

The more it swarms, crawls and flies the better it is for humans. This is the finding of a study published in "Nature". More than 60 researchers from a number of universities were involved, including the Technical University of Munich, the Institute of Plant Sciences at the University of Bern and the Senckenberg Biodiversity and Climate Research Centre in Frankfurt. A diverse ecosystem populated by many species from all levels of the food chain provides higher levels of ecosystem services, the team reports.

The impact of climate change on global seawater conditions could change the rules of sperm competition for many important marine species, a pioneering new study has shown.

"The Arctic sea ice responded very rapidly to past climate changes. During the coldest periods of the past 90,000 years the sea ice edge spread relatively quickly to the Greenland-Scotland Ridge, and probably far into the Atlantic Ocean." says first author Ulrike Hoff, a researcher at Centre for Arctic Gas Hydrate, Environment and Climate (CAGE).

Sea ice amplifies the climate changes that are occurring at any given time. Its growth and melting has profound effects on climate, the marine environment and ocean circulation.

Tiny pieces that complete the big picture

Oxford University researchers say that trees which grew during intense radiation bursts in the past have 'time-markers' in their tree-rings that could help archaeologists date events from thousands of years ago. In a new paper, the authors explain how harvesting such data could revolutionise the study of ancient civilisations such as the Egyptian and Mayan worlds. Until now scholars have had only vague evidence for dating when events happened during the earliest periods of civilisation, with estimates being within hundreds of years.

The recent outbreaks caused by Ebola and Zika viruses have highlighted the importance of medical and public health research in accelerating outbreak control and have prompted calls for researchers to share data rapidly and widely during public health emergencies.

WASHINGTON, D.C., August 16, 2016 -- When plaque, fatty deposits that build up on the inside of arteries, rupture and block blood flow, the results can be deadly. Such hardening of the arteries, also called atherosclerosis, typically leads to heart disease, the leading cause of death in the United States. Despite years of therapeutic advances, scientists are still figuring out how and why these deposits develop, searching for a way to reduce the number of heart attacks and strokes.

WASHINGTON, D.C., August 16, 2016 -- One of the most critical issues the United States faces today is preventing terrorists from smuggling nuclear weapons into its ports. To this end, the U.S. Security and Accountability for Every Port Act mandates that all overseas cargo containers be scanned for possible nuclear materials or weapons.

Detecting neutron signals is an effective method to identify nuclear weapons and special nuclear materials. Helium-3 gas is used within detectors deployed in ports for this purpose.

Wildfires threaten more than land and homes. The smoke they produce contains fine particles (PM2.5) that can poison the air for hundreds of miles. Air pollution from the 2016 Fort McMurray fire in northern Alberta, Canada sent people in Michigan to the hospital with respiratory illnesses.

As wildfires increase in frequency and severity due to climate change, more and more communities are at risk of prolonged exposure to harmful levels of smoke.

It is indisputable that greenhouse gases emitted into the atmosphere heat up our planet. But it is harder to determine the exact dependence of the temperature rise on greenhouse gas concentrations. Scientists refer to this dependence as climate sensitivity. If we assume that human activity leads to a sustained doubling of the CO2 concentration in the atmosphere, how much will the earth warm on average? "Probably between 1.5 and 4.5 degrees Celsius" was the vague answer of the Intergovernmental Panel on Climate Change (IPCC) in its most recent Assessment Report from 2013.

When hurricanes like Katrina in 2005 or Sandy in 2012 impact on highly populated regions they bring about tremendous damages. More than 50 percent of all weather-related economic losses on the globe are caused by damages due to tropical cyclones. Researchers from the Potsdam Institute for Climate Impact Research (PIK) now analyzed the magnitude of future hurricane losses in relation to economic growth.
