How did complex life evolve? The answer could be inside out
A new idea about the origin of complex life turns current theories inside out. Scientists explain their 'inside-out' theory of how eukaryotic cells, which all multicellular life -- including us -- are formed of, might have evolved.

Using microscopic bugs to save the bees
For decades, honeybees have been battling a deadly disease that kills off their babies -- larvae -- and leads to hive collapse. It's called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground. Now researchers have produced a natural way to eliminate the scourge, and it's working: Using tiny killer bugs known as phages to protect baby bees from infection.

Hot on the trail of the Asian tiger mosquito
The Asian tiger mosquito (Aedes albopictus) was spotted in Houston in 1985 but can now be found in all of the southern states and as far north as Maine. To reconstruct its spread, scientists turned to the new discipline of landscape genetics. Correlating genetic patterns with landscape patterns, they concluded that the mosquito had hitched a ride along highways. One of only a handful of landscape genetics studies to track an invasive species, this is the first to detect hitchhiking.

Combating parasitic worm infections by adapting breakthrough technologies
Experts are calling for researchers to adapt new technologies to research neglected parasitic flatworms. "It took several years of work to sequence the genomes of the major species of flatworm parasites. However, now that we have this information, we can focus on genes of interest," said a co-author.

Cell membranes self-assemble
A self-driven reaction can assemble phospholipid membranes like those that enclose cells. The new process is specific and non-toxic, and can be used in the presence of biomolecules one might want to study within artificial cells. The technique could also be used to assemble packets for drug delivery.

Vaccine candidate highly efficacious against bacterial diarrhea, clinical results indicate
A live attenuated enterotoxigenic Escherichia coli vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease, new results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate.

How staph infections elude the immune system
By tricking the immune system into generating antibodies specific for only one bacterial protein, Staphylococcus aureus dodges the production of antibodies that might otherwise protect against infection. Vaccine approaches must be designed to side-step this bacterial subterfuge, experts say.

The Ebola epidemic: Is there a way out?
Although no licensed vaccines against Ebola exist on the market, 'significant progress' has been made in the last few months, according to immunology experts.

Team discovers how microbes build a powerful antibiotic
Researchers have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.

New dent in HIV-1's armor: promising target for HIV/AIDS treatment
A promising target for HIV/AIDS treatment has been found by researchers who have have uncovered a new protein that participates in active HIV replication. The new protein, called Ssu72, is part of a switch used to awaken HIV-1 (the most common type of HIV) from its slumber. More than 35 million people worldwide are living with HIV and about a million people die a year due to the disease.
