How DNA 'proofreader' proteins pick and edit their reading material
Researchers have discovered how two important proofreader proteins know where to look for errors during DNA replication and how they work together to signal the body's repair mechanism.

Inspired by venus flytrap, researchers develop folding 'snap' geometry
Inspired by natural 'snapping' systems like Venus flytrap leaves and hummingbird beaks, a team led by physicist Christian Santangelo at the University of Massachusetts Amherst has developed a way to use curved creases to give thin curved shells a fast, programmable snapping motion. The new technique avoids the need for complicated materials and fabrication methods when creating structures with fast dynamics.

As Ice Age ended, greenhouse gas rise was lead factor in melting of Earth's glaciers
A new analysis of boulders left by retreating glaciers around the Earth as the last Ice Age ended has pinpointed rising carbon dioxide levels as the driving factor behind the simultaneous meltdown. The findings foreshadow the consequences of rapidly rising levels of greenhouse gases and retreating glaciers today.

Greenhouse gases caused glacial retreat during last Ice Age
A recalculation of the dates at which boulders were uncovered by melting glaciers at the end of the last Ice Age has conclusively shown that the glacial retreat was due to rising levels of carbon dioxide and other greenhouse gases, as opposed to other types of forces. The data helps to confirm predictions of future glacial retreat, and that most of the world's glaciers may disappear in the next few centuries.

Chapman University research on meat species shows mislabeling in commercial products
Researchers in Chapman University's Food Science Program have just published two separate studies on meat mislabeling in consumer commercial products. One study focused on identification of species found in ground meat products, and the other focused on game meat species labeling. Both studies examined products sold in the US commercial market; and both study outcomes identified species mislabeling among the product samples.

Carnegie Mellon-led team identifies structure of tumor-suppressing protein
An international group of researchers led by Carnegie Mellon University physicists Mathias Lösche and Frank Heinrich have established the structure of an important tumor suppressing protein, PTEN. Their findings provide new insights into how the protein regulates cell growth and how mutations in the gene that encodes the protein can lead to cancer.

A detector shines in search for dark matter
Results of the XENON100 experiment are a bright spot in the search for dark matter. The team of international scientists involved in the project demonstrated the sensitivity of their detector and recorded results that challenge several dark matter models and a longstanding claim of dark matter detection. Papers detailing the results will be published in upcoming issues of the journals Science and Physical Review Letters.

New data from Antarctic detector firms up cosmic neutrino sighting
Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos. The evidence is important because it heralds a new form of astronomy using neutrinos, the nearly massless high-energy particles generated in nature's accelerators: black holes, massive exploding stars and the energetic cores of galaxies.

Experiment attempts to snare a dark energy 'chameleon'
Is dark energy hard to detect because it's hiding from us? According to a recent theory, hypothetical particles called chameleons vary in mass depending on nearby matter: in the vacuum of space, they have a small mass and large reach, pushing space apart. In the lab, surrounded by matter, they have a large mass and small reach, making them difficult to detect. A UC Berkeley experiment seeks to find chameleons by lessening the screening.

Drought implicated in slow death of trees in southeast's forests
Damage suffered by trees during a drought can reduce their long-term survival for up to a decade after the drought ends, a new study of tree mortality in southeastern forests finds. By identifying the symptoms that mark a tree for later death and the species that are at highest risk, the study's findings may give managers and scientists a way to recognize and reverse drought-induced declines before it's too late.

Computer models show significant tsunami strength for Ventura and Oxnard, California
Ventura and Oxnard in California could be vulnerable to the effects of a local earthquake-generated tsunami, according to computer models used by research team, led by UC Riverside seismologists. According to their 3-D models, a magnitude 7.7 earthquake on faults located offshore Ventura would result in many parts of the regional coastline being inundated a few kilometers inland by a tsunami wave. Further, a southward moving tsunami would rotate and focus on the Ventura/Oxnard area.
