I Am Not This Body
by Perikis Livas in Tracing Knowledge
Every time I look at my face in a magnified mirror in a hotel bathroom, I jump back in surprise. Seen closely, my skin looks like the surface of a strange planet. Ridges and canyons pock my chin and lips. Forests of tiny hairs grow from my ear lobes. Unnoticed pimples rise from my nose like volcanoes. A sheen of oil coats the landscape. I half expect to see alien creatures living in minute settlements in my dimples or roving the great plains of my cheeks — and could I look at higher magnif........ Read more »

DNA analysis unearths origins of Minoans, the first major European civilization
by Perikis Livas in Tracing Knowledge
DNA analysis is unearthing the origins of the Minoans, who some 5,000 years ago established the first advanced Bronze Age civilization in present-day Crete. The findings suggest they arose from an ancestral Neolithic population that had arrived in the region about 4,000 years earlier.... Read more »

Body fat hardens arteries after middle age
by Perikis Livas in Tracing Knowledge
Having too much body fat makes arteries become stiff after middle age, a new study has revealed.
In young people, blood vessels appear to be able to compensate for the effects of obesity. But after middle age, this adaptability is lost, and arteries become progressively stiffer as body fat rises – potentially increasing the risk of dying from cardiovascular disease.... Read more »

Study IDs key protein for cell death
by Perikis Livas in Tracing Knowledge
When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA.
A new finding from MIT researchers may offer a way to overcome that resistance: The team has identified a key protein involved in an alternative death pathway known as programmed necrosis. Drugs that mimic the effects of this protein could push cancer cells that are res........ Read more »

Decoding the secrets of the sacred lotus
by Perikis Livas in Tracing Knowledge
Among other intriguing properties, the sacred lotus has the ability to generate heat and regulate its temperature like birds and mammals. It has been cultivated as a food crop for more than 7000 years in Asia and is prominent in both Buddhism and Hinduism.
An international team has sequenced and described the sacred lotus genome, now published online in Genome Biology. The paper sheds new light on the evolutionary position of the lotus, one of the world’s oldest flowering plants, and fa........ Read more »

Experience leads to the growth of new brain cells
by Perikis Livas in Tracing Knowledge
How do organisms evolve into individuals that are distinguished from others by their own personal brain structure and behaviour? Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they were able to show that individual experiences influence the development of new neurons, leading to measurable changes in the brain. The results of this study are published in Science on May 10th. The DFG-........ Read more »

A new class of tiny, injectable LEDs is illuminating the deep mysteries of the brain.
Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis developed ultrathin, flexible optoelectronic devices – including LEDs the size of individual neurons – that are lighting the way for neuroscientists in the field of optogenetics and beyond....

Exotic atoms hold clues to unsolved physics puzzle at the dawn of the universe
by Perikis Livas in Tracing Knowledge

Divide and define: Clues to understanding how stem cells produce different kinds of cells
by Perikis Livas in Tracing Knowledge
The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human, and passes identical copies of that information to each new cell as it divides into the many diverse types of cells that make up a complex organism like a human being....

Heart cells change stem cell behavior
by Perikis Livas in Tracing Knowledge
Stem cells drawn from amniotic fluid show promise for tissue engineering, but it’s important to know what they can and cannot do. A new study by researchers at Rice University and Texas Children’s Hospital has shown that these stem cells can communicate with mature heart cells and form electrical couplings with each other similar to those found in heart tissue. But these electrical connections alone do not prompt amniotic cells to become cardiac cells.... Read more »

More Than a Good Eye: Carnegie Mellon Robot Uses Arms, Location and More To Discover Objects

A robot can struggle to discover objects in its surroundings when it relies on computer vision alone. But by taking advantage of all of the information available to it – an object’s location, size, shape and even whether it can be lifted – a robot can continually discover and refine its understanding of objects, say researchers at Carnegie Mellon University’s Robotics Institute....

Radiation Health Risks

The ability to gauge radiation at vanishingly low concentrations gives scientists a powerful tool for understanding ocean processes. “We can measure down to less than 1 becquerel”—one radioactive decay event per second, said Ken Buesseler, a marine chemist at Woods Hole Oceanographic Institution. “But just because we can measure it doesn’t mean it’s necessarily harmful to human health.”...
