Modeling the past to understand the future of a stronger El Niño

El Nino is not a contemporary phenomenon; it’s long been the Earth’s dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Nino will respond.

The Great Harbor at Carthage

What is a Cothon? A cothon is a man-made harbor originated by the ancient Phoenicians. Technically, a cothon is a man-made island at the center of a harbor, but because this island was typically included in the harbor design, its name eventually became the general term for the type of harbor.

Still Fighting Reconstruction

I think there are a number of problems with Rev. Barber’s interpretation of Reconstruction, but I can’t help but acknowledge the ways in which the post-Civil War period seems to be creeping into our discourse about a host of issues related to racial politics in recent years. The sesquicentennial of Reconstruction Era offers a number […]

The living, breathing ocean

The ocean is a complex ecosystem. The ocean carbon cycle is governed by the relationship among carbon, nutrients and oxygen, and the ratio between certain elements is key to understanding ocean respiration.

Laser physicists 'see' how electrons make atomic and molecular transitions

By solving a six-dimensional equation that had previously stymied researchers, physicists have pinpointed the characteristics of a laser pulse that yields electron behavior they can predict and essentially control.

Copper on the brain at rest

Proper copper levels are essential to the health of the brain at rest, new research shows. The brain consumes 20-percent of the oxygen taken in through respiration. This high demand for oxygen and oxidative metabolism has resulted in the brain harboring the body's highest levels of copper, as well as iron and zinc. Show More Summary

Engineers make sound loud enough to bend light on a computer chip: Device could improve wireless communications systems

Engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control the light.

Heat-conducting plastic developed at U-Michigan

ANN ARBOR--The spaghetti-like internal structure of most plastics makes it hard for them to cast away heat, but a University of Michigan research team has made a plastic blend that does so 10 times better than its conventional counterparts. read more

More public health interventions required to tackle grim reaper of 'lifestyle' diseases

More public health interventions, along the lines of the smoking ban, are needed to tackle the devastating toll of 'lifestyle' diseases, including heart disease and cancer, according to academics.

An enzyme that fixes broken DNA sometimes destroys it instead, researchers find

Enzymes inside cells that normally repair damaged DNA sometimes wreck it instead, researchers have found. The insight could lead to a better understanding of the causes of some types of cancer and neurodegenerative disease.

Sexist passages

There are always two ways of looking at statements from the past where women are concerned. One of them is in comparison to our society. The other is from the standpoint of the society at the time. If you transport these statements into our time, the sound awfully sexist. Show More Summary

TGen-Luxembourg scientific team conducts unprecedented analysis of microbial ecosystem

FLAGSTAFF, Ariz. -- Nov. 26, 2014 -- An international team of scientists from the Translational Genomics Research Institute (TGen) and The Luxembourg Centre for Systems Biomedicine (LCSB) have completed a first-of-its-kind microbialShow More Summary

Angelina Jolie and the Mansion Tax

Oh noes, whatever are we to do? Angelina Jolie might be put off from moving Brad and the kids to London. Why? Because of the mansion tax. I'm sure some Tories are happy that Jolie has, as we used to say in Trot circles, objectively lined up with their opposition to the tax. Show More Summary

Elderly brains learn, but maybe too much

Learning requires both mental flexibility, or 'plasticity,' and stability. A new study finds that in learning a visual task, older people exhibited a surprising degree of plasticity, but had trouble filtering out irrelevant information, suggesting that their learning was not as stable.

Cognitive test battery developed to assess impact of long duration spaceflights on astronauts' brain function

A cognitive test battery, known as Cognition, has been developed for the National Space Biomedical Research Institute (NSBRI) to measure the impact of typical spaceflight stressors (like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance.

Enzyme may be key to cancer progression in many tumors

A deeper understanding of how KRAS turns off tumor suppressor genes and identifies a key enzyme in the process has been gained by researchers. The findings suggest that this enzyme, known as TET1, may be an important target for cancer diagnostics and treatment.

Research on rare cancer exposes possible route to new treatments

The unusual role of lactate in the alveolar soft part sarcoma has been uncovered by researchers who also confirm that a fusion gene is the cancer-causing agent in the disease.

Your Inner Voice: Friend or Foe?

Who is the person you speak to most frequently? Why, it’s yourself, of course. And what is the nature of those conversations? Do you tend to be harsh, nasty and punitive about who you are and what you’ve done (or haven’t done?) Do you frequently expect too much of yourself? Are you your own worst […]
