There is broad scientific interest in understanding the origin of the catalytic power of enzymes on a molecular level. While hypotheses have been put forward using experimental and computational approaches, they must be examined critically. In the Journal of Chemical Physics, researchers present a critical review of the dynamical concept—time-dependent coupling between protein conformational motions and chemical reactions—that explores all reasonable definitions of what does and does not qualify as a dynamical effect.
Berkeley Lab scientists have engineered a strain of bacteria that enables a “one-pot” method for producing advanced biofuels from a slurry of pre-treated plant material. The achievement, described in a study to be published May 10 in Green Chemistry, is a critical step in making biofuels a viable competitor to fossil fuels.
This week Argonne National Laboratory is releasing an updated version of its alternative fuels and advanced vehicles analysis tool to reflect the latest advances in alternative fuels and vehicle technologies and updated emissions data.

How easily did life arise on Earth, how likely is it on other planets? A new experiment strongly supports the idea that very early life coding molecules, ancestors of RNA and DNA, arose in primordial puddles with relative ease and speed, and not necessarily just in rarer fiery cataclysms.
A team at Kennesaw State University have developed a novel cell-penetrating peptide (CPP) technology capable of carrying other molecular “cargos” directly into living cells, coupling with them and then successfully uncoupling after delivering its payload. Cargos can be therapeutic molecules like antibodies that fight against parasites and diseases, or anti-cancer proteins.
Thanks to combination antiretroviral therapies, many people with HIV can expect to live decades after being infected. Yet doctors have observed these patients often show signs of premature aging. Researchers at University of California San Diego School of Medicine and the University of Nebraska Medical Center have applied a highly accurate biomarker to measure just how much HIV infection ages people at the cellular level — an average of almost five years.
UMMS scientists develop multicolored labeling system to track genomic locations in live cells.
Cancer is rarely the result of a single mutation in a single gene. Rather, tumors arise from the complex interplay between any number of mutually exclusive abnormal changes in the genome, the combinations of which can be unique to each individual patient. To better characterize the functional context of genomic variations in cancer, researchers at University of California San Diego School of Medicine and the Broad Institute developed a new computer algorithm they call REVEALER.

Epilepsy is a neurological disorder that causes seizures of many different types. Recent research from Japan has found that epileptic seizures can be more easily predicted by using an electrocardiogram to measure fluctuations in the heart rate than by measuring brain activity, because the monitoring device is easier to wear. By making more accurate predictions, it is possible to prevent injury or accident that may result from an epileptic seizure. This is a significant contribution toward the realization of a society where epileptic patients can live without worrying about sustaining injury from an unexpected seizure.
In his new book, “What We Talk About When We Talk About Clone Club,” international expert on the ethics of human cloning, Gregory Pence, explores issues raised in the sci-fi show “Orphan Black” about human cloning, its ethics and impact on personal identity, genetic enhancement, and other mysterious science. Pence takes a lighthearted look at cloning in popular culture and explains when the show gets the science right and when it doesn’t.

The company, Stemina Biomarker Discovery, specializes in detecting the byproducts of cellular activity and then applying high-powered statistics to detect patterns among thousands of metabolites.
Biopsies are a gold standard for definitively diagnosing diseases like cancer. Usually, doctors can only take 2-D snapshots of the tissue, and they're limited in their ability to measure the protein levels that might better explain a diagnosis. But now, researchers have developed a new method to acquire 3-D atlases of tissue that provide much more information, incorporating both data on the tissue structure and its molecular profile. They report their results in Biomicrofluidics.
Athletes, the elderly and others who suffer from injuries and arthritis can lose cartilage and experience a lot of pain. Researchers are now reporting, however, that they have found a way to produce cartilage tissue by 3-D bioprinting an ink containing human cells, and they have successfully tested it in an in vivo mouse model. The researchers present their work at the 251st National Meeting & Exposition of the American Chemical Society.
The ongoing debate about breast cancer diagnostics has left many women confused — particularly over what age they should get mammograms and who needs treatment. An issue with current methods is that they often identify lumps but cannot conclusively pinpoint which ones are cancerous. So, researchers have developed a pill that could improve imaging, lighting up only cancerous tumors. They report their work at the 251st National Meeting & Exposition of the American Chemical Society.
Drug therapies for many conditions end up treating the whole body even when only one part needs it. But this generalized approach can hurt healthy cells, causing nasty side effects. To send drugs to specific disease locations, researchers developed cellular “backpacks” that are designed to carry a therapeutic cargo only to inflamed disease sites. The researchers present their work at the 251st National Meeting & Exposition of the American Chemical Society.
