A new paper suggests that an increase in mobile phone ownership could have led to a rise in mental health problems in young people.

Doctor? Who?

New York University said Thursday that it will cover tuition for all its medical students regardless of their financial situation, a first among the nation’s major medical schools and an attempt to expand career options for graduates who won’t be saddled with six-figure debt [Editor’s note: the link may be paywalled]. From a report: School officials worry that rising tuition and soaring loan balances are pushing new doctors into high-paying fields and contributing to a shortage of researchers and primary care physicians. Medical schools nationwide have been conducting aggressive fundraising campaigns to compete for top prospects, alleviate the debt burden and give graduates more career choices. NYU raised more than $450 million of the roughly $600 million it estimates it will need to fund the tuition package in perpetuity, including $100 million from Home Depot founder Kenneth Langone and his wife, Elaine. The school will provide full-tuition scholarships for 92 first-year students — another 10 are already covered through M.D./PhD programs — as well as 350 students already partway through the M.D.-only degree program.

Now that we are starting to see the arrival of actual therapies aimed at targeting the processes of aging directly in order to prevent age-related diseases, it has become easier to separate two very distinct groups.

The first group consists of the snake oil salesmen peddling unproven supplements and therapies to whoever is foolish enough to buy and take things on faith without using the scientific method. The hucksters have long been a plague on our field, preying on the gullible and tainting legitimate science with their charlatanry and nonsense. One example is the “biotech company” that makes bold claims yet never delivers on those claims in practice, offering data based on poorly designed experiments and tiny cohorts that are statistically irrelevant; another example is the supplement peddler selling expensive supplement blends with flashy names, which, on inspection, turn out to be commonly available herbs and minerals mixed and sold at a high markup. These sorts of people have plagued our community and given the field a reputation of snake oil.

The second group are the credible scientists, researchers, and companies who have been working on therapies for years and sometimes more than a decade. Many of these therapies are following the damage repair approach advocated by Dr. Aubrey de Grey of the SENS Research Foundation over a decade ago. The basic idea is to take an engineering approach to the damage that aging does to the body and to periodically repair that damage in order to keep its level below that which causes pathology. These therapies are now starting to arrive, with some already in human trials right now, and this marks a milestone in our field: the credible science has finally outstripped the snake oil, and the focus can move from pseudoscience to real, evidence-based science.

Global investment in renewable energy (Solar, Wind, Hydro and biofuel) edged up 2% in 2017 to $279.8 billion, taking cumulative investment since 2010 to $2.2 trillion. The level of global renewable power spending has been virtually flat for seven years. There has been an increase in overall installed renewable power each year because of the dropping prices. A 2% increase in spending has resulted in 10% increase in global installations from 2016 to 2017.

A record 157 gigawatts of renewable power capacity was commissioned in 2017, up from 143GW in 2016. This was more than the 70GW of net fossil fuel generating capacity added last year. However, the installed fossil fuel power generates more kilowatt hours because of the low capacity factors of solar and wind power.

Last week, NASA announced the awardees for an ongoing effort to foster commercial activity in space. This effort allows 13 companies to study the future of commercial human spaceflight in low-Earth orbit, including long-term opportunities for the International Space Station.

I’m pleased to share that NanoRacks is one of these awardees.

This study is not only a big step for NanoRacks, but a big step for the commercial space ecosystem. Today, we are the largest commercial user of the International Space Station and are proud of the impact we’ve made to help foster this ecosystem and bring customers from all over the world into to orbit. This study will allow us to take our vision to the next step and detail the viability for habitable and automated platforms for low-Earth orbit.

The way research in quantum technology will be taken forward has been laid out in a revised roadmap for the field.

Published today in the New Journal of Physics, leading European quantum researchers summarise the field’s current status, and examine its challenges and goals.

In the roadmap:

Aggressive brain tumour cells taken from patients self-destructed after being exposed to a chemical in laboratory tests, researchers have shown.

The study could be the first step in tackling cancers like glioblastoma, which led to Dame Tessa Jowell’s death earlier this year.

The research, led by the University of Leeds, found that the synthetic chemical, named KHS101, was able to cut the energy source of tumour cells from glioblastoma, leading to the death of the cells.

It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries.

Cities produce and must manage huge quantities of wastewater. Researchers at the University of Illinois at Urbana-Champaign have developed a model to clarify what parts of the world may benefit most from re-circulation of human-waste-derived nitrogen, potassium and phosphorus from cities and back into farm fields. They report their findings in the journal Nature Sustainability.

“We grow our crops in the field, apply nutrient-rich fertilizers, eat the crops, excrete all of the nitrogen, phosphorus and potassium and then those nutrients end up at the wastewater treatment plant,” said Jeremy Guest, a civil and environmental engineering professor and study co-author. “It is a very linear, one-directional flow of resources. Engineering a more circular nutrient cycle would create opportunities that could benefit the environment, economy and agriculture.”
