Do you like Mexican chili? Hot and spicy... But if you think the problem posed by the beans is the "jet propulsion", you're wrong. Lectins, a type of proteins with natural insecticide qualities and found in abundance in raw legumes and grains, can have more severe temporary effects.Lectins strongly adhere to car... |

Although not very obvious, there is a link between termites, cows and cars: bacteria. Some of these little critters are helping cows and termites digest cellulose, and some can produce electrical current and could be used in fuel cells that could power up future ecological cars.A group of researchers at Penn State Un... |

The strong and prolonged contraction of a muscle during exercising causes sooner or later muscle fatigue. Researches showed that the fatigue increases while the glycogen stored in the muscles decreases. The glycogen is a glucose polymer, like an animal starch. When the muscle needs glucose to burn, the glycogen cuts ... |

Our immune system cannot be turned on or off like a light switch. On the contrary, it responds to an invasion of bacteria, viruses or parasites through a combination of defensive weapons which adapt smoothly to the situation. The simplest reaction of the immune system is for example that triggered by a mosquito bite:... |

You won't believe it, but there are women born with no vagina! A genetic condition, called Mayer-von Rokitansky-Küster-Hauser syndrome (MRKHS), affecting one in 5000 women, induces the lack of vagina development during embryogenesis. These patients can have a normal uterus, ovaries and external secondary sexual devel... |

Breasts represent femininity. Having small breasts can turn into an obsession for many women. You can imagine what losing them means for a woman! And this is exactly what happens in many cases of breast cancer. Many doctors have tried to take fat from other body parts (breasts are made mainly of fatty tissue) to buil... |

Couples undergoing IVF are struggling for years to have a baby and when this happens, it comes in a number bigger than 1, in at least 40 % of the cases. In fact, the latest cases of sextuplets are the result of IVF treatments. But the issue is that multiple pregnancies have worse outcomes and in many cases these bab... |

It is clear that stem cells research could boom the medical advance. Currently stem cells are extracted from human embryos, but there is a major ethical issue around this theme: the stem cells' extraction destroys the embryos. In US, this type of research does not receive federal funds. Ian Wilmut, famous for cl... |

Stem cells promise everything: from new hearts to new testes or eyes. Now, researchers have announced major advances in stem cell research: directly reprogramming fetal mouse cells to be indistinguishable from embryonic stem (ES) cells. This way scientists could get cell lines tailored to individual patients without ... |

HIV, the virus causing AIDS, impairs our immune system and it does it so well that till now, no cure has been found. A new Hopkins research explains how the virus manages to spread itself inside the body, infecting new cells. The findings reveal how unwittingly the organism implies in auto-infecting itself, not leavi... |

A fuel cell is an electrochemical energy conversion device. It produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the... |

This could satisfy both vegans and meat-eaters: lab grown meat. A Dutch team is trying to grow pork in a lab with the aim of delivering meat for millions without raising and slaughtering animals."We're trying to make meat without having to kill animals," said Bernard Roelen, a veterinary science professor at Utr... |

Harvesting solar energy is a clever way to make use of a clean and renewable fuel. You don't need to dig the ground for it, there are no pipes and powerplants, and best of all, it's ecological. Unfortunately, existent solar cells are not too efficient and can't convert more than 10 percent of the sola... |

After four years of research, researchers have discovered a way to engineer adult stem cells from human umbilical cord blood to synthesize insulin. This could lead to a revolutionary treatment against diabetes. "This discovery tells us that we have the potential to produce insulin from adult stem cells to help people... |

Inserting a gene into a cell is hard work. But it is even harder when it's about a plant cell. Now a team of Iowa State University has managed to do it and to trigger the gene's expression with controlled precision by using nanotechnology, a fact that could boost it as a novel powerful tool for delivery pro... |

Radiation is truly the invisible killer. Coming in the form of waves or moving subatomic particles, it's unheard and unseen and can only be felt after some time, when it's usually too late for a treatment. Currently, there is no effective treatment for radiation poisoning (also called radiation sickness),... |

It's like weighing a dream. Or a thought. Only that it's material. But researchers have succeeded in weighing a single living cell. Previous attempts resulted ineffective as any sample had to be dried, killing the cells. The new method allows for the weighing of samples as light as 1/1,000,000,000,000,000 g... |

We possess an inner clock that assigns as to be either an owl or a lark. Another inner clock reacts to seasons, that's why for some the winter is a reason for joy, while for others it can mean depression.

Solar energy would be the best energy source: cheap, renewable and non-contaminant. Now, after 10 years of research, a new solar cell technology developed by Massey University's Nanomaterials Research Centre could generate electricity from sunlight at a 10th of the cost of current silicon-based photo-electric so... |

Nanomaterials are regarded as a great hope for many medical fields, like fighting against tumors. But as in the case of every new technology, the size, type, and dispersion of nanomaterials are not well understood in how they could impact human health and the environment.

'A long way from the console games that processor has come, indeed,' (Yoda would comment on the subject), and now on to the dark side. Not having much success with the PS3, Sony is in quite a bad spot right now. Not to mention the exploding batteries phase they went through, it looks like they're not g... |
