As any dedicated video game player knows, the first requirement for using a weapon or tool is finding it. And it is no different for cell biologists and clinicians wh...

Combination therapy boosts effectiveness of telomere-directed cancer cell death

Sometimes apotential target for a drug seems very promising on paper; things areoften very different in reality. Its the case of telomerase inhibitorsto treat cancer; they are supposed to strip the "immortal" (able todivide indefinitely) aspect of cancer cells. Yet, something in the cellseems t...

Scientists find missing enzyme for tuberculosis iron scavenging pathway

...r survival," explains Dr. Baker. "Importantly this seems to be true even of the bacteria that are taken up by macrophages in the lung and enter a dormant state ?these are the hardest to attack with drugs." ...

Researchers reveal the infectious impact of salmon farms on wild salmon

... in each area parasite amplification on fish farms seems to increase disease levels in the local fish community. However previous studies have not shown nor quantified the direct transmission. This study captures the chain of events." "Part of the contentious debate about sea lice is that there hasn't bee...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...trate such complex assemblies of transcription? It seems certain that this is not the genome we learned about while in school." In the "traditional" view of the human genome, there are about 26,000 genes used to make proteins that ultimately control the structure and function of every cell in the body. Mo...

Critical role in programmed cell death identified

... death is conserved from worms to humans. "Now it seems that there is really one way of killing cells and it involves these mitochondria. Using genetics, we could rigorously show that mitochondria are part of it. It unifies two different hypothesis and makes worms a great model to analyze how cell death i...

Open microfluidic and nanofluidic systems

...er and a couple of micrometer. At first sight, it seems rather obvious to use such surface channels as microcompartments. However, if one actually tries to fill these channels with a certain liquid, one observes that the liquid often refuses to enter the channels. In fact, as shown in the new PNAS study, ...

Gene Vaccine Protects Mice Against Development Of Her2/neu Breast Cancer

HIV Infection Still On The Rise

...al catastrophe, the epidemic in the United Kingdom seems both small and parochial, say the authors. Nevertheless, the latest figures show a 20% increase in the prevalence of HIV in 2003 and 2004 compared with 2002, partly because of infections acquired abroad. Furthermore, each newly diagnosed HIV patient...

NYC's First Rapid HIV Drug-resistant AIDS Case Prompts Call to Step Up HIV Prevention

"Unfortunately, it also seems that few of the AIDS treatments currently available today can be used in his case, as his particular strain of infection appears to be resistant to most known AIDS drugs. AIDS care providers see many cases of patients with a high degree of some drug ...

New insight into people who 'see' colors in letters and numbers

...ia--in which people's sensory perceptual circuitry seems to be miswired--was long dismissed as an oddity not worthy of scientific study. Now, however, researchers such as Hubbard and his colleagues are using the condition to gain insights into the neural basis of perception. In their experiments with syne...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...carried normal or mutant copies of the genes. "It seems that these hothead-containing plants keep a cryptic copy of everything that was in the previous generation, even though it doesn't show up in the DNA, it's not in the chromosome," Pruitt said. "Some other type of gene sequence information that we don...

Bird Brains Show How Trial and Error May Contribute to Learning

"It means this part of the brain is important for instructing or allowing changes in the song," said Mimi Kao, f...

Love at first smell

Perhaps these results explain why some perfumes smell good on some people and terrible on others." Professor Thomas Boehm, Max-Plank Society said: "The new results raise the question of whet...

In the migratory marathon, parasitized monarchs drop out early
