Technology: ‘Nuro R2’ Self-Driving Delivery Vehicle Completes Test Drives In 3 States (Video)

Earlier this year, our self-driving delivery robot R2 became the first autonomous vehicle to receive an approved exemption from the US Department of Transportation.

R2 then became the second autonomous vehicle to receive a driverless testing permit in California. When the COVID-19 pandemic hit, we set up contactless delivery services with R2 at temporary care facilities in California to carry food, water, and medical supplies to patients and doctors with the goal of decreasing points of contagion.

Today, we’re excited to announce another first for Nuro. For the past few months, R2 has been testing on city streets fully autonomously in three different states. No drivers. No occupants. No chase cars.

Adventure Travel: Rafting 30-Miles In South Alaska’s Tongass National Forest

Photographs and Text by Christopher Miller for The New York Times – October 19, 2020

As Bjorn and I push through thickets of devil’s club and trundle over chest-high nurse logs, the trees seem to grow before our eyes. The forest stands as a witness to the passage of time, and a nearby stream as a lifeline to the past.

The saplings at the confluence of the stream mark the present, while the giant spruce and hemlock at its source likely predate the European colonization of the Americas — so that the only humans who could have witnessed the birth of this stand of trees are the area’s Tlingit and Haida peoples.

It’s late April 2019, and my traveling companion, Bjorn Dihle, and I are on a four-day, 30-mile excursion through the heart of Prince of Wales Island along the Honker Divide Canoe Route, the island’s longest trail. We have forgone the canoes and opted for packrafts due to their size and weight; they’re easier to schlep over logs and across the many short portages.

Science Podcasts: Beetle’s Strong Exoskeleton Helps Engineers, Covid-19 Trials

The structure of a beetle’s super-strong exoskeleton could open up new engineering applications, and efforts to address diversity and equality imbalances in academia.

In this episode:

01:17 Insights into an armoured insect

The diabolical ironclad beetle has an exoskeleton so strong, it can survive being run over by a car. Researchers have identified how the structure of the exoskeleton provides this strength, and show that mimicking it may lead to improved aerospace components.

10:42 Coronapod

This week, the UK government announced plans to run a ‘human challenge trial’, where healthy volunteers are deliberately infected with the SARS-CoV-2 virus. We talk about the process, the ethical and procedural hurdles, and whether such an approach will provide any useful data.

25:20 Efforts to address equity in science

Julie Posselt has been investigating the efforts of academic institutions to assess ingrained imbalances in diversity and equality. We talk to her about these efforts and her new book on the subject.

We discuss some highlights from the Nature Briefing. This time, back pay for female professors at Princeton, and a newly uncovered superpower for the tiny tardigrade.

Ocean Culture & Sports: Spearfishing On North Shore Of O’ahu, Hawai’i

What does it mean to be connected to our food? What is the balance between taking life and giving life?

Based on the North Shore of O’ahu, IMPRINT is the story of two souls, whose lives have intertwined with the ocean. Shane Hamamoto, who has lost the ability to spearfish and dive, from barometric trauma now expresses his passion for the ocean through Gyotaku – the traditional art of Japanese fish printing.

Alicia Holland, a young spearfisher woman from the Big Island of Hawai’i, has taken her love for the ocean to support her family and as an outlet through nature. She recognizes that she is growing up in an age of abundance and grocery stores – the aching unnaturalness of modern amenities has had her resort back to the thrill of the hunt.

We follow her life as she navigates the taboos and rewards associated with spearfishing.

Sustainable Architecture: ‘Anandaloy In Bangladesh’ – Made of Bamboo & Mud

designed by german architect anna heringer, ‘anandaloy’ is a community center and workshop in bangladesh that is made from mud and bamboo. located in rudrapur, a village in the country’s dinajpur district, the two-storey building contains a therapy center for people with disabilities at ground level and a fair-trade textile manufacturing workshop for local women on the first floor. below a big ramp that connects the two levels, protective cave-like spaces provide settings for recreation or solitude.

Bangladesh, to the east of India on the Bay of Bengal, is a South Asian country marked by lush greenery and many waterways. Its Padma (Ganges), Meghna and Jamuna rivers create fertile plains, and travel by boat is common. On the southern coast, the Sundarbans, an enormous mangrove forest shared with Eastern India, is home to the royal Bengal tiger.

Health: ‘Diabetes And Chronic Kidney Disease’ – New Guidelines (OCt 2020)

Comprehensive care in patients with diabetes and CKD

Management of CKD in diabetes can be challenging and complex, and a multidisciplinary team should be involved (doctors, nurses, dietitians, educators, etc). Patient participation is important for self-management and to participate in shared decision-making regarding the management plan. (Practice point).

We recommend that treatment with an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin II receptor blocker (ARB) be initiated in patients with diabetes, hypertension, and albuminuria, and that these medications be titrated to the highest approved dose that is tolerated (1B).

Lifestyle interventions in patients with diabetes and CKD

We suggest maintaining a protein intake of 0.8 g protein/kg)/d for those with diabetes and CKD not treated with dialysis (2C).

On the amount of proteins recommended in these guidelines, they suggest (‘recommend’ becomes a ‘suggest’ at this level of evidence) a very precise  intake of 0.8g/kg/d in patients with diabetes and CKD. Lower dietary protein intake has been hypothesized but never proven to reduce glomerular hyperfiltration and slow progression of CKD, however in patients with diabetes, limiting protein intake below 0.8g/kg/d can be translated into a decreased caloric content, significant weight loss and quality of life. Malnutrition from protein and calorie deficit is possible.

Physical activity

We recommend that patients with diabetes and CKD be advised to undertake moderate-intensity physical activity for a cumulative duration of at least 150 minutes per week, or to a level compatible with their cardiovascular and physical tolerance (1D).
