Study: office workers can ditch standing desks by taking short walks instead

Study: office workers can ditch standing desks by taking short walks instead

There seems to be three stages involved in owning a standing desk. First, you feel enthusiastic about your renewed work environment and optimistic about its effects on your health. Soon enough, though, you start to feel distracted by the discomfort of standing all the time. Then, finally, you acknowledge that humans invented chairs for a reason and return to your previous sedentary ways. According to a new study, that's fine: there's a suitable alternative to standing desks.

NASA Langley Mars habitat concept is made of ice

NASA Langley Mars habitat concept is made of ice

NASA is working on a lot of the components required to send man to Mars. From the rockets that will carry the astronauts to the Red Planet to the structures the astronauts will live in on the surface of the planet, NASA is working on all aspects. The latest concept for a dwelling on the surface of the Red Planet uses an unusual and rather simple building material - ice.

2016 will get an extra second to keep precision time devices precise

2016 will get an extra second to keep precision time devices precise

I'd wager that we are all familiar with the leap year, this is the year when February gets an extra day. Some will be familiar with a similar concept called the leap second and the last time a leap second was added to the clock as June 30, 2015. 2016 will get a leap second to keep precision clocks that precisely track time accurate. This leap second will come at the end of 2016.

Researchers develop nanodiscs to deliver personalized cancer therapy

Researchers develop nanodiscs to deliver personalized cancer therapy

Researchers from the University of Michigan have reported success in cancer research with mice using a new delivery method for therapies called nanodiscs. The researchers were able to use the nanodiscs to deliver a customized therapeutic vaccine for the treatment of colon and melanoma cancer tumors. Personalized immunotherapy is a growing field of research for cancer treatments.

Self-assembly process builds nanowires with tiny 3-atom wide copper-sulfur crystalline core

Self-assembly process builds nanowires with tiny 3-atom wide copper-sulfur crystalline core

Stanford University researchers with help for the US Department of Energy's SLAC National Accelerator Laboratory have created a new self-assembly process that that uses something called diamondoids to create tiny nanowires that have a solid core. That solid core inside the tiny nanowires is made from a 3-atom wide copper-sulfur crystalline material and is the smallest core possible. The tiny nanowires have superior electrical properties due to the lack of defects in the solid crystalline core.

NASA’s space laser is used to study phytoplankton

NASA’s space laser is used to study phytoplankton

NASA has a laser inside a satellite orbiting the Earth and the laser is being used to study the boom-and-bust cycle of polar ocean plants. Specifically the laser is being used to study the peak and decline cycles of phytoplankton in the ocean. NASA says that its findings will supply data for ecosystem management, commercial fisheries, and help our understanding of the climate and key ocean ecosystems.

China plans to soft land probe on far side of the moon by 2018

China plans to soft land probe on far side of the moon by 2018

China has announced its space ambitions for the coming years and it has some big plans. The first thing that China plans to do is place a probe on the far side of the moon. China wants to soft land a probe on the far side of the moon by 2018 and accomplishing this feat would make it the first country to do so.

Cheetahs are closer to extinction than anyone knew

Cheetahs are closer to extinction than anyone knew

A mere 7,100 cheetahs remain the wild, a new study has confirmed, putting the wild cats perilously close to extinction and spurring demands that they be officially classed as "endangered". The striking big cats, which hold the record as the world's fastest land animal, are currently considered "vulnerable" on the IUCN Red List of Threatened Species. That, the authors of a new study insist, paints the actual situation in too rosy a way.

Researchers lambast study associating HPV vaccine with brain damage

Researchers lambast study associating HPV vaccine with brain damage

Vaccines are a hot topic and, unfortunately, the source of ample criticism by those who fear they cause autism and other conditions. The latest vaccine to reach alarm status is the HPV vaccine, which deals with the human papilloma virus and aims to prevent cervical cancer in women. This vaccine is recommended for women and girls, and is also increasingly being given to boys, but a new study has undermined confidence in it, associating it with brain damage in mice.

Edipeel invisible food coating keeps fruit fresh for weeks

Edipeel invisible food coating keeps fruit fresh for weeks

Fresh food is great assuming you live near a suitable market, have a way to properly store the food, and you can consume it all before it goes bad. Things like lettuce, green onions, strawberries, and other fruits and vegetables are prone to going bad relatively quickly after being purchased, though, making it unappealing to many consumers, not to mention the waste that results. One company, fortunately, may have a solution.

This odd dinosaur changed drastically as it aged

This odd dinosaur changed drastically as it aged

In the Gobi desert a new sort of dinosaur has been discovered which changed drastically from birth to age six. Using a total of 19 sets of bones, paleontologists show how Limusaurus inextricabilis ("mire lizard who could not escape") changed in big ways in the first year of its life. Researchers have shown how baby versions of this dinosaur had teeth, but that these teeth left the dinosaur within a year. But what about reptiles in our modern age that lose and grow several sets of teeth? This research has an answer for that, and other oddities, too.

DEKA’s LUKE arm delivered to Walter Reed to help US veterans

DEKA’s LUKE arm delivered to Walter Reed to help US veterans

The LUKE prosthetic arm is taking another big step today, as DARPA has delivered the first two arms to the Walter Reed National Military Medical Center (WRNMMC). These arms, along with others from a new production line, will be prescribed to veterans in need of them. The WRNMMC will select the veterans that will get these arms, and the manufacturers of the LUKE - Mobius Bionics - will train Walter Reed physicians on how the arms function and how to fit patients with them.
