 Astrophysical Journal Letters{DISSERTATION} First black holes born starving The first black holes in the universe had dramatic effects on their surroundings, according to recent simulations carried out at the SLAC/Stanford Kavli Institute for Particle Astrophysics and Cosmology. Several popular theories posit that the first black holes gorged themselves on gas clouds and dust, growing into the supersized black holes that lurk in the centers of galaxies today. However, the new results point to a much more complex role for the first black holes.

Environmental Science & Technology{DISSERTATION} Carbon nanoparticles toxic to adult fruit flies but benign to young Researchers at Brown University have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae. The findings, published online in Environmental Science & Technology, may further reveal the environmental and health dangers of carbon nanoparticles.

{DISSERTATION} Dark energy from the ground up: Make way for BigBOSS To measure the expansion history of the universe, the design chosen for the Joint Dark Energy mission will use three techniques -- supernovae, weak lensing, and baryon acoustic oscillation -- but it will emphasize baryon acoustic oscillation. Good science, but many scientists think it can be done better, cheaper, and more dependably from the ground -- by BigBOSS.

Journal of Physical Chemistry{DISSERTATION} Protein folding: Diverse methods yield clues Rice University physicists have written the next chapter in an innovative approach for studying the forces that shape proteins. Featured on the cover of today's issue of the Journal of Physical Chemistry, the new research illustrates the value of studying proteins with a new method that uses the tools of nanotechnology.

{DISSERTATION} Carnegie donates landmark clones to biology Surprisingly little is known about the interactions that proteins have with each other and the protective membrane that surrounds a cell. These membrane proteins regulate nutrients, sense environmental threats, and are the communications interface between and within cells. Now researchers at the Carnegie Institution have cloned genes to produce membrane proteins that may initiate instructions for genes to turn on in the nucleus. They just donated 2,010 of them to the Arabidopsis Biological Resource Center.

Journal of Neuroscience{DISSERTATION} Beep, beep, oops, what was I doing? "That blasted siren. I can't focus." That reaction to undesired distraction may signal a person's low working-memory capacity, according to a new study. Based on a study of 84 students divided into four separate experiments, University of Oregon researchers found that students with high memory storage capacity were clearly better able to ignore distractions and stay focused on their assigned tasks.

Angewandte Chemie{DISSERTATION} New cancer drug delivery system is effective and reversible Cancer drugs must be effective. But they must also target cancer cells and spare healthy cells. And -- ideally -- they'll come with an easy antidote. University of Illinois researchers report that they have developed a cancer drug delivery system that achieves all of the above.

Science{DISSERTATION} Scientists devise efficient way of learning about complex corn traits There's no "silver bullet" gene or gene region that controls so-called complex traits in maize, commonly known as corn. Instead, in two research papers published this week in the journal Science, North Carolina State University crop scientists and colleagues show that lots of small changes in a number of gene regions affect complex traits -- like flowering time or reproductive ability -- in corn.

Science{DISSERTATION} Penn researchers show that protein unfolding is key for understanding blood clot mechanics Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to cardiovascular disease. The answer is a process known as protein unfolding.

Science{DISSERTATION} Long debate ended over cause, demise of ice ages -- may also help predict future Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years -- they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.

Nature{DISSERTATION} Shaking the Earth: Just add water New Zealand is the site of one of the world's youngest subduction zones, where the Pacific Plate of Earth's crust dives beneath the Australian Plate. Now, a University of Utah study shows how water deep underground helps the subduction zone mature and paves the way for it to generate powerful earthquakes.

Proceedings of the National Academy of Sciences{DISSERTATION} African village dogs are genetically much more diverse than modern breeds African village dogs are not a mixture of modern breeds but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral African village dogs.

Biophysical Journal{DISSERTATION} Bone's material flaws lead to disease The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease, stem from a genetic mutation that causes the incorrect substitution of a single amino acid in the chain of thousands of amino acids making up a collagen molecule, the basic building block of bone and tendon.

{DISSERTATION} Successful completion of first riser-drilling operations in earthquake zone The deep-sea drilling vessel CHIKYU has drilled successfully down to a depth of 1,603.7 meters beneath the seafloor (water depth 2,054 meters). It is drilling deep into the upper portion of the Nankai Trough earthquake zone to gain insights into geological formations and stress-strain characteristics. The operations began on May 12; the science party is expected to complete the first drill site on or about August 1.
