Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

...althier polyunsaturated fats are those that remain liquid at room temperature, such as various types of vegetable oils. Trans-unsaturated fatty acids, or trans fats, are artificially produced solid fats used in shortening and margarine, baked goods, and the oils used to cook french fries and other fast foo...

University of Manchester makes made-to-measure skin and bones a reality using inkjet printers

...printer, the cells are suspended in anutrient rich liquid not dissimilar to ink, which ensures theirsurvival. The cells are then fed into the printer and seeded directlyinto the structure as it is built. This avoids any 'sticking to thesurface' which is a major disadvantage of current methods that infusethe...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

...hemical analysis technique called high-performance liquid chromatography to survey the pigments present in red parrot feathers. McGraw and Nogare collected and analyzed samples from 44 parrot species that have red feathers. Overall, there are some 350 species of parrots, 80 percent of which have red in thei...

Scientists develop new color-coded test for protein folding

... and graduate student Matthew R. Hammond created a liquid solution containing nano-sized particles of gold saturated with a protein called cytochrome c. "We chose gold nanoparticles because they are simple to prepare, easy to control and cost effective," the authors wrote. "To the best of our knowledge, ho...

Development of portable infectious disease detector

..., pumps and valves to move around minuteamounts of liquid on silicon chips proved to be considerably moredifficult than most of the inventors had expected and the products thatthese companies have created thus far have been too expensive for thepoint-of-care diagnostics market.For their home fertility teste...

Breakthrough method in nanoparticle synthesis paves the way for new pharmaceutical and biomedical applications

...r, these catalysts normally exist in a homogeneous liquid phase, which makes them difficult to be separated and reused. Prof. Ying’s group at IBN has developed novel approaches to immobilize these catalysts on nanoporous materials synthesized by its wet-chemical technique. This renders the catalysts in a s...

...lected from her ovaries, which were then frozen in liquid nitrogen at ?96ºC. After a period of two months, the eggs were thawed and fertilized with her partner's sperm through in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), and the resulting embryos implanted in her uterus. "The p...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...be cooled fast enough that the transformation from liquid to solid is instantaneous. No ice crystals form and the consistency resembles a viscous glassy state. Research so far has used mouse oocytes but U-M expects to make the technology available in the clinic soon. "With traditional slow-freeze technique...

Could microbes solve Russia's chemical weapons conundrum?

... that was first used in World War I. Found in both liquid and aerosol form (mustard gas), it can cause severe burns to the skin, and severe damage to the respiratory system and internal organs if ingested or inhaled. It accounts for around 2 percent of Russia's CWA stockpile. Around 60 percent of the musta...
