The Ten Best Science Books of 2017

But the best science and tech writing goes one step further. With delight and mystery—and sans unnecessary jargon and technical details—this genre can help us better understand some of the world’s most complex and abstract concepts, from gravitational waves (Gravity’s Kiss) to Darwinian evolution (The Evolution of Beauty) to antibiotic resistance (Big Chicken). Each of these remarkable tomes from 2017 does just that, shining a light on the hidden connections and invisible forces that shape the world around us. In doing so, they make our experience of that world that much richer.

Science Is Starting to Explore the Gray Zone Between Life and Death

Biologist Mark Roth, at Seattle’s Fred Hutchinson Cancer Research Center, is working with animal subjects, putting them into suspended animation. The idea is that a patient who is in medical crisis could be put into a suspended state like hibernation, until he or she could be stabilized and in this way, get past it.

Though we tend to expire when the oxygen level is low, many animals go into a suspended state in extremely low oxygen environments. In the lab, one must enter into such an environment quickly. Roth is currently working with nematodes—a kind of roundworm—and expects to eventually work up to humans.

A vegetative state is another aspect of what we consider the gray zone between life and death. Medically, this is when sufficient damage to the brain has occurred, where the person isn’t aware of and can’t respond to their surroundings. They may breathe, have a heartbeat, move their eyes, even show reflexes, but they can’t respond to stimuli or interact with the world. Their brain stem is operating normally, but other parts of the brain may be damaged or inoperable. Most patients who enter such a state never leave it.

The real science behind the unreal predictions of major earthquakes in 2018

The research got a lot of attention after Bilham presented it at the October meeting of the Geological Society of America. Several critics noted that correlation is not causation — earthquake clusters and fluctuations of Earth’s rotation might happen on the same time scales, but that doesn’t mean they are linked.

There’s a curious connection between earthquakes and the Earth’s rotation. But that doesn’t mean the planet is in for a major shaking next year.

Maximize the impacts of space science

In our view, to get the most from space-science programmes — in terms of impacts on research and reputation — government agencies and institutions need to choose, manage and assess missions in ways that optimize the scientific outputs. As heads of space-science agencies and institutes from around the world gather at a forum next week in Beijing to identify principles for maximizing returns on such missions, we call on them to put science first.

Put research goals first when prioritizing and managing national and international projects, urge Ji Wu and Roger Bonnet.

Fifty years since the first United Nations Conference on the Exploration and Peaceful Uses of Outer Space (1968 — 2018): UNISPACE+50 — United Nations Office for Outer Space Affairs (UNOOSA)

“UNISPACE+50 will celebrate the fiftieth anniversary of the first United Nations Conference on the Exploration and Peaceful Uses of Outer Space. It will also be an opportunity for the international community to gather and consider the future course of global space cooperation for the benefit of humankind.

From 20 to 21 June 2018 the international community will gather in Vienna for UNISPACE+50, a special segment of the 61 st session of the Committee on the Peaceful Uses of Outer Space (COPUOS).”

Why Longer Lives Thanks to Science Will Probably Not Create Cultural Stagnation

You probably know the quote by Steve Jobs saying that death is life’s single best invention because it gets rid of the old and makes room for the new. This view is the core of another fairly common objection to rejuvenation, codename “cultural stagnation”.

Wouldn’t all those rejuvenated people, however physically young, be always old people “inside”, and drag everyone down with them into their anachronistic, surpassed ways of thinking, making it harder for fresh ideas to take hold, ultimately hindering social progress and our growth as a species? Maybe it’d be best not to take the risk, forget rejuvenation, and be content with old age as it is.

Well, try explaining to your grandfather that the reason he has to put up with heart disease is that we’re afraid people his age may all become troublemakers when you let them live too long.

3 Ways Science Might Help You to Live Longer

Today, we take a look at three key emerging technologies that might add extra healthy years to your life by addressing the aging processes directly to prevent or delay age-related diseases.

Senolytics – Removing aged dysfunctional cells to promote tissue regeneration

As we age, increasing amounts of our cells enter into a state known as senescence. Normally, these cells destroy themselves by a self-destruct process known as apoptosis and are disposed of by the immune system. Unfortunately, as we age, increasing numbers of these cells evade apoptosis and linger in the body.

Why do some People Fear Using Science to Live Longer Healthy Lives?

With the recent surge of enthusiastic support for LEAF/Lifespan.io and the idea of defeating aging, I really shouldn’t be complaining about the lingering holdouts opposing the idea of living healthy and longer lives for whatever reason. Nonetheless, I feel compelled to point out the jarring contradiction of a species whose members are constantly on the lookout to avoid danger, yet need to be reassured that at some point they will die and that science is by no means trying to prevent that.

Fear of life extension

This curious phenomenon was pointed out earlier this year by James Goodwin in the journal of the Gerontological Society of America[1]. In his article “Fear of life extension”, he argues that the commandment of geriatrics is “quality, not quantity” because policymakers fear a future in which longer life means overpopulation of nursing homes, and as a consequence, researchers working on interventions on aging need to clearly state that their goal is just making our final years a little better—but making us live longer? God forbid, no! We only want to live in perfect health for about 80 or 90 years, then magically drop dead for no apparent reason.
