Bipolar: What Mania Looks Like for Me

What is a grandiose idea in bipolar disorder? Most people believe that’s something like believing you are Jesus or a superhero. I have had bipolar disorder for most of my life and never experienced such feelings. I never understood what it could feel like until recently. I was reading […]

the party decides that they hate ted cruz

A lot of people have slammed The Party Decides for not getting this year’s primary completely correct. But I take a different view. The Democratic primary is going as planned, so that supports the theory pretty well. Even on the GOP side, there is some evidence that party dynamics are working as expected. So let’s […]

A cleansing rain falls; a soil-filled mist arises

RICHLAND, Wash. - Most of us think of that sweet smell after a storm as the aftereffect of rain that has rinsed the air of pollutants and dust. But it turns out that rain also triggers the release of a mist of particles from wet soils into the air, a finding with consequences of its own for how scientists model our planet's climate and future. read more

Cardiovascular risk tool overestimates actual chance of cardiovascular events

OAKLAND, Calif., May 2, 2016 -- A widely recommended risk calculator for predicting a person's chance of experiencing a cardiovascular disease event -- such as heart attack, ischemic stroke or dying from coronary artery disease -- has...Show More Summary

Three potentially habitable worlds found around nearby ultracool dwarf star

A team of astronomers led by Michaël Gillon, of the Institut d'Astrophysique et Géophysique at the University of Liège in Belgium, have used the Belgian TRAPPIST telescope [1] to observe the star 2MASS J23062928-0502285, now also known as TRAPPIST-1. read more

Cavitation aggressive intensity greatly enhanced using pressure at bubble collapse region

Researchers at Tohoku University are developing a method to improve the aggressive intensity of cavitation without the need to increase the input power. Cavitation - the formation, growth and subsequent collapse of microbubbles - produces...Show More Summary

A climate warming warning: Warmer temperatures are affecting lakes in the oilsands region

Scientists have identified climate warming as the dominant driver of an increase in algal growth in the Athabasca oilsands region of northern Alberta.

Health sensing tool measures lung function over a phone call, from anywhere in the world

Researchers have developed SpiroCall, a new health sensing tool that can accurately measure lung function from anywhere in the world over a simple phone call. It is designed to work with older mobile phones and landlines, not just smartphones.

UC San Diego bioengineers create first online search engine for functional genomics data

University of California San Diego bioengineers have created what they believe to be the first online search engine for functional genomics data. This work from the Sheng Zhong bioengineering lab at UC San Diego was just published online by the journal Nucleic Acids Research. This new search engine, called GeNemo, is free for public use at: read more

Adult brain prunes branched connections of new neurons

LA JOLLA -- (May 02, 2016) When tweaking its architecture, the adult brain works like a sculptor -- starting with more than it needs so it can carve away the excess to achieve the perfect design. That's the conclusion of a new study that tracked developing cells in an adult mouse brain in real time. read more

How much does groundwater contribute to sea level rise?

Groundwater extraction and other land water contribute about three times less to sea level rise than previous estimates, according to a new study published in the journal Nature Climate Change. The study does not change the overall picture...Show More Summary

Nearly half of heart bypass patients skip medications that keep blood flowing

Researchers at Thomas Jefferson University discovered that nearly half of coronary artery bypass patients are not taking statins and aspirin together when they are referred for diagnostic cardiac catheterization at least three years after their initial bypass. Their results are currently in press online in the American Journal of Cardiology. read more

Hurricanes key to carbon uptake by forests: Increases in carbon uptake by southeast US forests in response to tropical cyclone activity alone exceed carbon emissions by American vehicles each year

New research reveals that the increase in forest photosynthesis and growth made possible by tropical cyclones in the southeastern United States captures hundreds of times more carbon than is released by all vehicles in the US in a given year.

World's tiniest engine small enough to enter living cells

Researchers have built a nano-engine that could form the basis for future applications in nano-robotics, including robots small enough to enter living cells.

Earth may be home to one trillion species

Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to a study from biologists. The estimate is based on the intersection of large datasets and universal scaling laws.

Method stabilizes, enhances phosphorene

A research team used organic chemistry to covalently react a single-molecule-thick layer onto phosphorene to stabilize its reactivity to open air.

Psychiatric symptoms impact mental health court engagement

People living with mental illness are overrepresented in the criminal justice system. Interventions to help this population, such as mental health courts, are becoming popular across the country. New research finds that for mental health...Show More Summary
