AZL Architects modernizes rural Chinese stone house with 3D printed pavilion

Chinese architecture firm AZL Architects has used 3D printing as part of a new house built in a rural Chinese village. The LEI House in Shanyinwu has a main building built from stone using traditional methods, which contrasts with an outer pavilion that was put together from 400 3D printed plastic blocks. via 3ders.org, http://www.3ders.org/articles/20180430-azl-architects-modernizes-rural-chinese-stone-house-with-3d-printed-pavilion.html

Sluggish ocean currents caused European heat wave some 12,000 years ago

A study published in Nature Communications investigates how the strong cooling of the North Atlantic Ocean impacted the European climate around 12,000 years ago. The findings could help scientists predict how climate change will exacerbate European heat waves and droughts in the future. A system of currents known as the Atlantic Meridional Overturning Circulation typically carries warm water from the …Continue reading →

Collapse of the Atlantic Ocean heat transport might lead to hot European summers

Severe winters combined with heat waves and droughts during summer in Europe. Those were the consequences as the Atlantic Ocean heat transport nearly collapsed 12,000 years ago. The same situation might occur today, according to a new study. Study authors Barbara Wohlfarth and Frederik Schenk during field work. The ancient lake site of Hässeldala in southern Sweden is one of …Continue reading →

3D printed heart helps Rice students develop cutting-edge wireless pacemaker

A team of engineers at Rice University has developed a design for a new pacemaker device, and used a 3D printed heart for a demonstration. Their device would embed tiny sensor chips within the heart, which communicate wirelessly with a base station and deliver energy when problems are detected. via 3ders.org, http://www.3ders.org/articles/20180430-3d-printed-heart-helps-rice-students-develop-cutting-edge-wireless-pacemaker.html

Did last ice age affect breastfeeding in Native Americans?

The critical role that breast feeding plays in infant survival may have led, during the last ice age, to a common genetic mutation in East Asians and Native Americans that also, surprisingly, affects the shape of their teeth. Photograph of human upper incisors with significant “shoveling,” anatomical variation influenced by the EDAR V370A allele alongside an increase in mammary duct …Continue reading →

Earth BioGenome Project aims to sequence DNA from all complex life on Earth

An international consortium of scientists is proposing what is arguably the most ambitious project in the history of biology: sequencing the DNA of all known eukaryotic species on Earth. The Earth BioGenome Project aims to sequence the DNA of all known eukaryotic species on Earth, a massive group that  includes plants, animals, fungi and other organisms [Credit: Juan Carlos Castilla-Rubio …Continue reading →
