Cockroach cyborgs use microphones to detect, trace sounds
Researchers have developed technology that allows cyborg cockroaches, or biobots, to pick up sounds with small microphones and seek out the source of the sound. The technology is designed to help emergency personnel find and rescue survivors in the aftermath of a disaster.

Transitions between states of matter: It's more complicated, scientists find
The seemingly simple process of phase changes -- those transitions between states of matter -- is more complex than previously known, according to research based at Princeton University, Peking University, and NYU.

Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria
Biogeochemical signals in 2.5-billion-year-old carbonate rocks from Brazil reveal that sulfur-consuming bacteria were active at a time when ocean sulfur levels were low. Geology graduate student Iadviga Zhelezinskaia is the first researcher to focus on sulfur isotopes in ancient carbonate rocks. Her study sheds light on Earth's early atmospheric chemistry, and appears in the Nov. 7 issue of Science.

Madagascar: Fossil skull analysis offers clue to mammals' evolution
The surprise discovery of the fossilized skull of a 66- to 70-million-year-old, groundhog-like creature on Madagascar has led to new analyses of the lifestyle of the largest known mammal of its time by a team of specialists including biologist Elizabeth Dumont at the University of Massachusetts Amherst, an expert in jaw structure and bite mechanics.

Coexist or perish, new wildfire analysis says
An international team of fire experts led by UC Berkeley's Max Moritz concluded that it is time to stop fighting fires and instead develop strategies to live with fire. In many areas, fire management is difficult or impossible, and interferes with fire's key role in the ecosystem. Instead, we should develop zoning and building codes and evacuation protocols to allow people to live with fire, just as we now live with earthquake and tornado hazards.

How important is long-distance travel in the spread of epidemics?
When modeling the spread of epidemics, such as the Ebola outbreak, scientists must take into account the long-distance hops now possible with international air travel. But how important are such long-distance jumps? A new model by biophysicists Oskar Hallatschek of UC Berkeley and Daniel Fisher of Stanford shows that how common long-range jumps are makes a big difference in the dispersal of a disease, that is, whether you get slow, rippling versus rapid metastatic spread.

Study shows tectonic plates not rigid, deform horizontally in cooling process
The puzzle pieces of tectonic plates are not rigid and don't fit together as nicely as we were taught in high school. A study published in the journal Geology by Corné Kreemer, an associate professor at the University of Nevada, Reno, and his colleague Richard Gordon of Rice University, quantifies deformation of the Pacific plate and challenges the central approximation of the plate tectonic paradigm that plates are rigid.

New insight into the neuroscience of choking under pressure
Recent research from the Johns Hopkins University suggests that in situations like this, performance depends on two factors: the framing of the incentive in terms of a loss or a gain, and a person's aversion to loss.

Less reward, more aversion when learning tricky tasks
We can easily learn by seeking reward or avoiding punishment. But either way, we'd rather have any task be easy. A new study finds a direct behavioral and physiological linkage between those inclinations: When even subtle conflict made an experimental task harder, it affected the perception of reward and punishment, skewing how subjects learned the task.

NYU study points to perception divide in abortion: Whom we think we know

Ultracold disappearing act
How can two clumps of matter pass through each other without sharing space? Rice University physicists have documented a strange disappearing act by colliding Bose Einstein condensates that appear to keep their distance even as they pass through one another. The research is published online this week in Nature Physics.

Getting more out of nature: Genetic toolkit finds new maximum for crop yields
CSHL scientists have found a new way to dramatically increase crop yields. The team has discovered a set of gene variations that boost fruit production in the tomato plant by as much as 100 percent. Plant breeders will be able to combine different gene variants to create an optimal plant architecture for particular varieties and growing conditions. The set will enable farmers to maximize yield in tomatoes and potentially other flowering plants, including crops like soybeans.

Breaking down DNA by genome
A new study in the November issue of Applications in Plant Sciences provides plant biologists with an efficient approach for separating plant nuclear DNA from organellar DNA for genomic and metagenomic studies. The approach targets the methyl-CpG-binding domain and allows researchers to isolate nuclear, chloroplast, and mitochondrial DNA, and can also target genomes of endophytes and prokaryotic parasites in plant DNA samples.
