A machine prototype called Farma can let you manufacture your daily prescription of drugs right in your own home. Designed by MIT Media Lab graduate Will Patrick, the concept tech features a green cylinder and uses blue-green algae that’s genetically engineered to produce pharmaceutical drugs.
In the future, you might be able to skip the pharmacy and, instead, make your treatments along with your morning breakfast.

Optogenetic laser light stimulation of the thalamus (credit: Jia Liu et al./eLife)
By flashing high-frequency (40 to 100 pulses per second) optogenetic lasers at the brain’s thalamus, scientists were able to wake up sleeping rats and cause widespread brain activity. In contrast, flashing the laser at 10 pulses per second suppressed the activity of the brain’s sensory cortex and caused rats to enter a seizure-like state of unconsciousness.
“We hope to use this knowledge to develop better treatments for brain injuries and other neurological disorders,” said Jin Hyung Lee, Ph.D., assistant professor of neurology, neurosurgery, and bioengineering at Stanford University, and a senior author of the study, published in the open-access journal eLIFE.
We’re coming down the homestretch for 2015, and now is the time when most folks like to reflect on all of the things they’re thankful for. In the campus innovation space, that basically means MIT. Being one of the most technologically progressive universities in the world, MIT has the longstanding reputation of churning out life-changing innovations as if it were a cake walk.
This past year has been no different. Here are our picks of 5 inventions coming out of MIT that are sure to impact the world, making us very thankful to have the Cambridge-based university in our corner.
If everyone’s bodies were true to textbook anatomy, doctors’ jobs would be a breeze. Unfortunately, that’s not the case. So all patients going in for heart surgery will have slightly different nuances to their cardiac makeup. As you can imagine, these procedures present some high stakes, so it’s not great for surgeons to be surprised in the OR.
Researchers in Japan have found that human aging may be able to be delayed or even reversed, at least at the most basic level of human cell lines. In the process, the scientists from the University of Tsukuba also found that regulation of two genes is related to how we age.
The new findings challenge one of the current popular theories of aging, that lays the blame for humans’ inevitable downhill slide with mutations that accumulate in our mitochondrial DNA over time. Mitochondrion are sometimes likened to a cellular “furnace” that produces energy through cellular respiration. Damage to the mitochondrial DNA results in changes or mutations in the DNA sequence that build up and are associated with familiar signs of aging like hair loss, osteoporosis and, of course, reduced lifespan.
So goes the theory, at least. But the Tsukuba researchers suggest that something else may be going on within our cells. Their research indicates that the issue may not be that mitochondrial DNA become damaged, but rather that genes get turned “off” or “on” over time. Most intriguing, the team led by Professor Jun-Ichi Hayashi was able to flip the switches on a few genes back to their youthful position, effectively reversing the aging process.
Healthy living isn’t meaningless, but while all of us can make positive lifestyle modifications, genes play a massive role in longevity — or there would be no species variation. We’re still discovering exactly which genes provide a longevity boost and what they do, but we now know 7 variants could help give you an advantage.
The search for a longevity gene
Previous efforts to search out a ‘longevity gene’ have been largely unsuccessful, so researchers led by Stuart Kim at Stanford decided to focus on ‘bad’ gene variants this time — or more crucially a lack of them. They analysed 800 people over 100 and 5000 people over 90 and found that while many variants are common in the average person, possession of fewer ‘bad’ versions of 5 crucial genes was indeed associated with longevity. Many long-lived individuals are able to avoid chronic disease despite harmful lifestyle choices like smoking, and this could be one of the explanations. These confirmed 5 add to 2 already associated with longer lifespans.
Robots and artificial intelligence (AI) will dominate legal practice within 15 years, perhaps leading to the “structural collapse” of law firms, a report predicting the shape of the legal market has envisaged.
Civilisation 2030: The near future for law firms, by Jomati Consultants, foresees a world in which population growth is actually slowing, with “peak humanity” occurring as early as 2055, and ageing populations bringing a growth in demand for legal work on issues affecting older people.
This could mean more advice needed by healthcare and specialist construction companies on the building and financing of hospitals, and on pension investment businesses, as well as financial and regulatory work around the demographic changes to come; more age-related litigation, IP battles between pharmaceutical companies, and around so-called “geriatric-tech” related IP.
Scanning the genomes of centenarians showed that four genes help them live longer. The discovery could boost the search for ways to protect against age-related diseases.
US army’s report visualises augmented soldiers & killer robots.
The US Army’s recent report “Visualizing the Tactical Ground Battlefield in the Year 2050” describes a number of future war scenarios that raise vexing ethical dilemmas. Among the many tactical developments envisioned by the authors, a group of experts brought together by the US Army Research laboratory, three stand out as both plausible and fraught with moral challenges: augmented humans, directed-energy weapons, and autonomous killer robots. The first two technologies affect humans directly, and therefore present both military and medical ethical challenges. The third development, robots, would replace humans, and thus poses hard questions about implementing the law of war without any attending sense of justice.
Augmented humans. Drugs, brain-machine interfaces, neural prostheses, and genetic engineering are all technologies that may be used in the next few decades to enhance the fighting capability of soldiers, keep them alert, help them survive longer on less food, alleviate pain, and sharpen and strengthen their cognitive and physical capabilities. All raise serious ethical and bioethical difficulties.
