Twin study shows what's good for the heart is good for the brain
Researchers are giving us double the reasons to pay attention to our cardiovascular health – showing in a recent study that good heart health can equal good brain health.

Resistance to last resort drug arose in patient over 3 weeks
French investigators have described development of resistance to one of the last resort therapies used to treat extremely drug-resistant Pseudomonas aeruginosa. That resistance arose in a single patient over a scant 22 days. They subsequently identified the single nucleotide mutation in P. aeruginosa that caused the resistance.

Scientists demonstrate a new approach in fluorescence microscopy that can be used to locate individual biomolecules in 3D space with nanometer-scale precision.
Read moreLarge-scale afforestation of African savannas will destroy valuable ecosystems
Scientists from around the world argue that the suggested afforestation of large areas of Africa to mitigate climate change will destroy valuable ecological, agricultural, and tourist areas, while doing little to reduce global CO2 levels.
Read moreAntarctic ice cliffs may not contribute to sea-level rise as much as predicted
Researchers report that in order for a 90-meter ice cliff to collapse entirely, the ice shelves supporting the cliff would have to break apart extremely quickly, within a matter of hours — a rate of ice loss that has not been observed in the modern record.

New research presents the first demonstration of a specific difference in sperm function associated with sex ratio skewing.
Read moreUnique brain changes in people with Huntington's disease
The part of the brain that selectively degenerates in people with Huntington's disease (HD), called the striatum, is almost entirely destroyed in the late stages of the disease. Brain samples from mutant HD gene positive individuals who had not yet developed symptoms by time of death are extremely rare. As a consequence, very little is known about the active disease process that causes the devastating symptoms of HD.
Read moreNovel method turns any 3D object into a cubic style
Computer scientists have developed a computational method to quantify an abstract cubic style. Additionally, their method also enables users to create new shapes that resemble the input shape and exhibit the cubic style.
Read moreIt takes two — a two-atom catalyst, that is — to make oxygen from water
The search for sustainable approaches to generating new fuels has brought scientists back to one of the most abundant materials on Earth — reddish iron oxide in the form of hematite, also known as rust.
Read moreDefining the centromere
Centromeres are the chromosomal domains at which the kinetochore, a protein complex required for the correct separation of chromosomes during mitosis and meiosis, is assembled. The incorporation of the histone variant CenH3 into centromeric nucleosomes is a prerequisite for the proper assembly and function of the kinetochore. A new study describes the chaperone protein NASPSIM3 and how it affects the depositioning of CenH3.
