Study shows lizard moms dress their children for success

...in which exposure to the mother's hormones changes such a fundamental aspect of appearance. Even more exciting is that the mother has different patterns at her disposal, so she can ensure a good match between back patterns and other traits that her offspring possess," said Lesley Lancaster, a UCSC graduat...

Women well informed about breast cancer, yet lacking knowledge about current treatments

... than one out of four had heard of newer therapies such as aromatase inhibitors or monoclonal antibodies, nor were they informed about their benefits. Doctor-patient dialogue is vital If diagnosed, the majority of respondents said they would actively work with their doctor to identify the proper t...

Progress toward an antitumor vaccine

...rapy. The difficulty with this approach is that such sugar-containing compounds are completely ineffective at stimulating the immune system to form antibodies. “Immunization is only successful if the vaccine is anchored to an immunizing carrier protein by means of a spacer,” explains Kunz. This would b...

Microbes at work cleaning up the environment

... Sulfate-reducing bacteria can cause heavy metals such as zinc (Zn) to precipitate and form nanoparticles. However, these particles are able to move freely because they are so small (typically 2-6 nanometers in diameter) and can redissolve if conditions change. In the case of the mine bacteria, the r...

New findings challenge established views on human genome

...arked just the first step toward the goal of using such information to diagnose, treat and prevent disease. Having the human genome sequence is similar to having all the pages of an instruction manual needed to make the human body. Researchers still must learn how to read the manual’s language so they can...

Plants recognize their siblings, biologists discover

...ws plants are capable of complex social behaviours such as altruism towards relatives, says Dudley. Like humans, the most interesting behaviours occur beneath the surface. Dudley and her student, Amanda File, observed the behavior in sea rocket (Cakile edentula), a member of the mustard family native ...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...it possible to insert relatively large structures, such as sensors and hollow filaments called carbon nanotubes, into the interiors of cells. The sensors could make it possible to monitor activities inside a single cell for the early detection of cancer and other diseases and to monitor the progress of...

The advantage of our approach is that the graft could utilize the patient’s own stem cells and be ready for implantation almost immediately or, at most, after a relatively short...
