Humans have the same receptors for detecting odors related to sex as do other primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to researchers.

Delivering medicine directly into a tumor

Researchers have identified a peptide (a chain of amino acids) that specifically recognizes and penetrates cancerous tumors but not normal tissues. The peptide was also shown to deliver diagnostic particles and medicines into the tumor.

Fine-tuned laser: Step toward airport scanners that can identify explosives

Engineers have developed the first practical method for tuning terahertz quantum cascade lasers. What's more, the method is a fundamentally new approach to laser tuning that could have implications for other emerging technologies.

H1N1 influenza adopted novel strategy to move from birds to humans

The 2009 H1N1 virus, which ignited a worldwide "swine flu" panic earlier this year, used a novel strategy to cross from birds into people, scientists have found. The finding could help those surveilling the world for new flu variants and those developing antiviral drugs.

Hunt for Higgs boson: Mass of top quark narrows search

New high-energy particle research by a team working with data from Fermi National Accelerator Laboratory heightens uncertainty about the exact nature of a key theoretical component of modern physics -- the massive fundamental particle, the Higgs boson. Particle collision data resulting in two leptons helped improve measurements of the mass of the heavy subat […]

Playing favorites: Parents still involved after children are grown

Middle-aged parents are more involved in their grown children's lives than ever, according to new research.

Everyday germs in childhood may prevent diseases in adulthood

A new study suggests that American parents should ease up on the antibacterial soap. Exposure to infectious microbes early in life may actually protect children from cardiovascular diseases that can lead to death as an adult. The study is the first to look at how microbial exposures early in life affect inflammatory processes related to diseases associated w […]

Stem cells can be engineered to kill HIV, scientists show

Researchers have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells -- a process that potentially could be used against a range of chronic viral diseases. The study provides proof-of-principle -- that is, a demonstration of feasibility -- that human stem cells can be engineered […]

How to read brain activity with an EEG

The electroencephalogram is widely used by physicians and scientists to study brain function and to diagnose neurological disorders. However, it has remained largely unknown whether the electrodes on the head give an exact view of what is happening inside the brain. Scientists have now found a crucial link between the activity generated within the brain to t […]

Women with breast cancer who consume soy food have lower risk of cancer recurrence

Although there is a concern regarding the safety of soy food consumption among breast cancer survivors, researchers have found that women in China who had breast cancer and a higher intake of soy food had an associated lower risk of death and breast cancer recurrence, according to a new study.
