'Living' micro-robot could detect diseases in humans
- ScienceDaily
- 12/3/29 17:21
A tiny prototype robot that functions like a living creature is being developed which one day could be safely used to pinpoint diseases within the human body. Called 'Cyberplasm', it will combine advanced microelectronics with latest research in biomimicry. The aim is for Cyberplasm to have an electronic nervous system, 'eye' and 'nose' sensors derived from mammalian cells, as well as artificial...

Scientists have developed a new method to detect proteins associated with longevity, which helps further our understanding into why some animals live longer than others.
Neutrons uncover new density waves in fermion liquids
- ScienceDaily
- 12/3/29 17:20
Scientists discover zero-sound mode oscillations in super-chilled helium. Scientists have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered a new type of very short wave-length density wave. The team believe their discovery will interest researchers looking at electronic systems, since high-temperature superconductivity could result...
New insights into how cells duplicate their DNA
- ScienceDaily
- 12/3/29 16:19
Scientists have discovered new insights into how cells duplicate their DNA. They used an imaging method known as cryo-electron microscopy to take extremely high resolution images of how the right proteins come together at the right point on the DNA strands, forming a structure called an "origin recognition complex" (ORC). The lab's first-of-a-kind images (taken using yeast cells, which are also...

Researchers have identified a number of tiny but powerful "genetic regulators" that are hijacked by avian and swine flu viruses during human infection.
Key component in mother's egg critical for survivial of newly formed embryo
- ScienceDaily
- 12/3/29 16:18
Scientists have discovered that a protein, called TRIM28, normally present in the mother's egg, is essential right after fertilization, to preserve certain chemical modifications or 'epigenetic marks' on a specific set of genes. This newly published study paves the way for more research to explore the role that epigenetics might play in...
Scientists clone 'survivor' elm trees
- ScienceDaily
- 12/3/29 16:18
Scientists have found a way to successfully clone American elm trees that have survived repeated epidemics of their biggest killer -- Dutch elm disease. The breakthrough is the first known use of in vitro culture technology to clone buds of mature American elm trees.
Culprit behind unchecked angiogenesis identified

Researchers have unraveled a critical regulatory mechanism controlling blood vessel growth that might help solve drug resistance problems in the future.
MicroRNAs offer new hope against obesity and diabetes
- ScienceDaily
- 12/3/29 16:16
Hunger has always threatened humankind. This makes it unsurprising that human bodies attempt to store all surplus nourishment in adipose tissue. In developed countries, this life-saving craving is turning into a problem and obesity -- adiposity -- is turning into a danger. Why, though, does excess fat the body ill? How does fat trigger diabetes? And can these superfluous fat reserves be turned...
Mites form friendly societies: Predatory mites who stick with familiar individuals are more efficient at finding food
- ScienceDaily
- 12/3/29 16:16
For plant-inhabiting predatory mites, living among familiar neighbors reduces stress. This allows individuals to focus on other tasks and be more productive, in particular while they are foraging. The new study supports the theory that so-called 'social familiarity' reduces the cognitive, physiological and behavioral costs of group-living, leading to increased efficiency in other...
Supercomputers help explain why there is almost no anti-matter in our universe
- ScienceDaily
- 12/3/29 16:16
Powerful supercomputers have shed light on the behavior of key sub-atomic particles, in a development that could help explain why there is almost no anti-matter in our universe. Physicists have reported a landmark calculation of the decay of an elementary particle called a kaon, using breakthrough techniques on some of the world's fastest supercomputers. This revealed the first experimental...
Dolphins cultivate loose alliances
- ScienceDaily
- 12/3/29 16:15
Dolphins behave uniquely. On the one hand, male dolphins form alliances with others; on the other hand, they live in an open social structure. Anthropologists from the University of Zurich detected this unusual behavior in the animal kingdom in dolphins in Shark Bay,...
Researchers close in on vaccine to protect babies

Researchers are closing in on a needle-free vaccine for respiratory syncytial virus (RSV), a major cause of respiratory illness in children under two years of age.
Current chemical testing missing low-dosage effects of endocrine-disrupting chemicals
- ScienceDaily
- 12/3/29 16:09
Endocrine-disrupting chemicals (EDCs) —- such as BPA —- can show tangible effects on health endpoints at high dosage levels, yet those effects do not predict how EDCs will affect the endocrine system at low doses, according to a recent study.
Met office to provide space weather warnings for planet Earth and forecasts for exoplanets
