 | A model that computes the fraction of the 'haystack' that SETI programs have collectively examinedWhy haven't we found evidence of life anywhere but Earth? A trio of astrophysicists has revisited this question by taking a closer look at the "needle in a haystack" analogy. Their analysis involved creating a model to assess the amount of work that has been done searching for extraterrestrial life, the Search for Extra-terrestrial Intelligence (SETI) project, compared to how much is required before scientists can rule out the possibility that there is none. Jason Wright, Shubham Kanodia and Emily Lubar have written a paper describing their efforts and uploaded it to the arXiv preprint server. |

 | Making head or tail of a galactic landscapeAstronomers have used data from NASA's Chandra X-ray Observatory to capture a dramatic image of an enormous tail of hot gas stretching for more than a million light years behind a group of galaxies that is falling into the depths of an even-larger cluster of galaxies. Discoveries like this help astronomers learn about the environment and conditions under which the Universe's biggest structures evolve. |

 | One black hole or two? Dust clouds can explain puzzling features of active galactic nucleiResearchers at the University of California, Santa Cruz (UCSC), believe clouds of dust, rather than twin black holes, can explain the features found in active galactic nuclei (AGNs). The team publish their results today (14 June) in a paper in Monthly Notices of the Royal Astronomical Society. |

 | Exploring the microscopic structure of black holes from the viewpoint of thermodynamicsSince the first detection of gravitational waves by LIGO and VIRGO, black holes have aroused widespread discussion and interest. For scientists, black holes play a unique role in connecting quantum mechanics and general relativity. The microscopic structure of black holes has always been a huge problem for scientists. A recent study reveals the microscopic mystery of black holes from the viewpoint of thermodynamics. |

 | Cancer hijacks the microbiome to glut itself on glucoseCancer needs energy to drive its out-of-control growth. It gets energy in the form of glucose, in fact consuming so much glucose that one method for imaging cancer simply looks for areas of extreme glucose consumption—where there is consumption, there is cancer. But how does cancer get this glucose? A University of Colorado Cancer Center study published today in the journal Cancer Cell shows that leukemia undercuts the ability of normal cells to consume glucose, thus leaving more glucose available to feed its own growth. |

Medicaid expansions linked to slower rises in overdose deathsThe United States in recent years has increased healthcare access by broadening Medicaid coverage, but some worry that these Medicaid expansions lead to more abuse of prescription painkillers and thus worsen the opioid epidemic. A new study suggests that Medicaid expansions may, in fact, have the opposite effect. In a study examining the potential impact of 2001-02 Medicaid expansions by Arizona, Maine and New York—expansions that occurred just prior to the rise in overdose mortality nationwide—researchers from the Perelman School of Medicine at the University of Pennsylvania found that from the time of these expansions through 2008, overdose mortality rates (mostly driven by fatal overdoses of opioids) rose significantly less in the expansion states than in non-expansion states. The study is published online this month in the Journal of General Internal Medicine. | |

Cryopreservation giving kids with cancer a brighter futureIn recent years, significant strides in pediatric cancer research have drastically decreased the odds of children dying after they are diagnosed.

One of the newest ways is a procedure called cryopreservation. | |
Wearables could inform selective mutism research, diagnosis, treatmentIn a new study published in the journal Frontiers in Psychiatry, a team led by Child Mind Institute researchers found that specially-designed wearable devices that passively capture and quantify child vocalization features have the potential to inform research into selective mutism by providing standardized, objective measurements that can aid in diagnosis and assess the efficacy of treatment approaches. Selective Mutism (SM) is an anxiety disorder often diagnosed in early childhood that is characterized by persistent failure to speak in certain social situations, but not others. | |
Researchers identify factors linked to mortality after traumatic brain injuryModel system researchers have examined the factors associated with mortality among individuals aged 16 years and older who were more than one year post- traumatic brain injury (TBI).
