This Black Hole Just Let Scientists Look Back in Time to the Dawn of Creation

(CAPE CANAVERAL, Fla.) — Astronomers have discovered a super-size black hole harkening back to almost the dawn of creation. It’s the farthest black hole ever found. A team led by the Carnegie Observatories‘ Eduardo Banados reported in the journal Nature on Wednesday that the black hole lies in a quasar dating to 690 million years of the Big Bang. That means the light from this quasar has been traveling our way for more than 13 billion years. Banados said the quasar provides a unique baby picture of the universe, when it was just 5 percent of its current age. It would be like seeing photos of a 50-year-old man when he was 2 1/2 years old, according to Banados. “This discovery opens up an exciting new window to understand the early universe,” he said in an email from Pasadena, California. Quasars are incredibly bright objects deep in the cosmos, powered by black holes devouring everything around them. That makes them perfect candidates for unraveling the mysteries of the earliest cosmic times. The black hole in this newest, most distant quasar is 800 million times the mass of our sun. Much bigger black holes are out there, but none so far away — at least among those found so far. These larger black holes have had more time to grow in the hearts of galaxies since the Big Bang, compared with the young one just observed.

By CHADI NABHAN MD MBA Life is busy, yet we somehow find time to stay engaged on social media, remain engrossed in the 24/7 news cycle, and continue our futile efforts to resist clickbait. While social media can allow us to mindlessly scroll through feeds, it also provides an avenue to provoke vigorous dialogue, however diverse, controversial, or even rooted in unfettered biases. These exchanges have served as the primordial soup for virtual friend or foe-ships. Tense and argumentative Twitter exchanges are especially entertaining given the challenges in justifying a position in fewer than 280 characters. Thus, tweetorial...

In conclusion, in the Framingham Heart Study population, in the last 30 years, disease duration in persons with dementia has decreased. However, age-adjusted mortality risk has slightly decreased after 1977-1983. Consequences of such trends on dementia prevalence should be investigated. Recent Research on the Benefits of Exercise in Later Life https://www.fightaging.org/archives/2018/04/recent-research-on-the-benefits-of-exercise-in-later-life/ A sizable body of work points to the ability of older individuals to continue to obtain benefits through regular physical activity, and particularly in the case ...

For the past 20 years, the Medical Design Excellence Awards have celebrated medical products that improve the quality and accessibility of healthcare. Our finalists this year carry on this tradition, while also keeping in step with today’s high-tech digital and consumer trends. With the help of our esteemed jurors, we have identified four key trends in this year’s group of finalists: risk reduction; faster, more-efficient healthcare delivery; the influence of the Internet of Things; and the consumerization of healthcare. We’ve been tracking a few of these trends in past awards programs, so they’re n...

I have blogged in the past about how the mission and nature of hospitals in the U.S. is changing rapidly (see, for example:The Design of Bedless Hospitals Continue to Evolve Based on Cost and Technology; Some Additional Ideas About the Bedless Hospitals of the Future; The Case of the"Disappearing Hospital Beds"; Implications for Pathologists). This same idea was covered in a somewhat controversial recent article by Ezekiel Emanuel with the provocative headline that asked whether hospitals were becoming obsolete (see:Are Hospitals Becoming Obsolete?). Below is an excerpt from it:What year saw the ma...

PHILADELPHIA (AP) — It was an ordinary surgery to remove a tumor — until doctors turned off the lights and the patient’s chest started to glow. A spot over his heart shined purplish pink. Another shimmered in a lung. They were hidden cancers revealed by fluorescent dye, an advance that soon may transform how hundreds of thousands of operations are done each year. Surgery has long been the best way to cure cancer. If the disease recurs, it’s usually because stray tumor cells were left behind or others lurked undetected. Yet there’s no good way for surgeons to tell what is cancer and what is not...

Are Consumer Health Care Products Accurate &Safe Enough for Your Healthcare? At CES, the monstrous electronics show, I saw lots of consumer devices advertised for personal fitness and healthcare. There was even a Digital Health Summit, with a wide range of industry experts. Some companies were promoting their ability to send data to healthcare providers. That’s scary, since there are no standards governing many of these devices. A clear message from CES is that the divisions between ‘technology’ and ‘devices’ are diminishing. Alexa, Google Home, and Siri, won’t be tied to stand-alone...

In conclusion, death is a natural part of human existence, but human progress is essentially a story of overcoming undesirable natural limits. In the near future, technological progress might make it possible to stop natural biological death. Should humankind embrace such technology? Yes: Even though such technology would not be without risks, the risks are almost certainly manageable. The benefits of ending natural death, on the other hand, are immense. Death is an obstacle that is slowing down human progress. If we remove that obstacle, humankind could increase the speed of both its moral and its epistemic progress. ...

How do you enter conversations with people you don’t know? I grew up with gregarious parents and have enthusiastically emulated them. Although my mother referred to herself as shy, I never observed her that way. She seemed to be able to engage with people in various scenarios. My father was raised in South Philly (home of the iconic pugilist character Rocky) where talking to people on the stoop or street corner was commonplace. He learned how to communicate with those from all walks of life from his own blue collar, working class sensibilities. No matter where our family went, it seems my father always knew someone,...

In January 2013 . . . after eight years of " citizen journalism " in the " progressive " Greensboro N.C. ether . . . after all of the political flame-wars and even getting cyber-stalked . . .

All I wound up doing was was telling the story onemore time. This post is that sidebar - it's as...
