Genetically driven gut feelings help female flies choose a mate

Genetically driven gut feelings help female flies choose a mate

Even among flies, mating is a complicated ritual. Their elaborate, and entirely innate, courtship dance combines multiple motor skills with advanced sensory cues. Now, researchers at Rockefeller University have determined that the Abdominal-B ( Abd-B ) gene, previously known as the gene that sculpts the posterior parts of the developing fly, is also important for this complex behavior, at least in the case of female flies ( Drosophila melanogaster) Continue reading

Obesity in Pacific islands ‘a colonial legacy’ of settlers trying to civilize the locals

Obesity in Pacific islands ‘a colonial legacy’ of settlers trying to civilize the locals

Scientists have known for some time that Pacific islanders are more prone to obesity than people in other nations. Continue reading

Shrink-wrapping spacesuits: Spacesuits of the future may resemble a streamlined second skin

Shrink-wrapping spacesuits: Spacesuits of the future may resemble a streamlined second skin

For future astronauts, the process of suiting up may go something like this: Instead of climbing into a conventional, bulky, gas-pressurized suit, an astronaut may don a lightweight, stretchy garment, lined with tiny, musclelike coils. She would then plug in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around her body. Continue reading

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Study after study has proven it true: exercise is good for you. But new research from University of Pennsylvania scientists suggests that exercise may have an added benefit for cancer patients undergoing chemotherapy. Their work, performed in a mouse model of melanoma, found that combining exercise with chemotherapy shrunk tumors more than chemotherapy alone. Continue reading

VIP: New way to prevent spread of devastating diseases

VIP: New way to prevent spread of devastating diseases

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren’t working Continue reading

New insights on an ancient plague could improve treatments for infections

New insights on an ancient plague could improve treatments for infections

Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections. In a study published online Sept Continue reading

Technique to model infections shows why live vaccines may be most effective

Technique to model infections shows why live vaccines may be most effective

Vaccines against Salmonella that use a live, but weakened, form of the bacteria are more effective than those that use only dead fragments because of the particular way in which they stimulate the immune system, according to research from the University of Cambridge published today. The BBSRC-funded researchers used a new technique that they have developed where several populations of bacteria, each of which has been individually tagged with a unique DNA sequence, are administered to the same host (in this case, a mouse) Continue reading

New molecule allows for up to 10-fold increase in stem cell transplants

New molecule allows for up to 10-fold increase in stem cell transplants

Investigators from the Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal have just published, in the journal Science , the announcement of the discovery of a new molecule, the first of its kind, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical cord stem cells are used for transplants aimed at curing a number of blood-related diseases, including leukemia, myeloma and lymphoma. Continue reading

Living in disadvantaged neighborhood worsens musculoskeletal pain outcomes after trauma exposure

Living in disadvantaged neighborhood worsens musculoskeletal pain outcomes after trauma exposure

Individuals living in disadvantaged neighborhoods have worse musculoskeletal pain outcomes over time after stressful events such as motor vehicle collision than individuals from higher socioeconomic status neighborhoods, even after accounting for individual characteristics such as age, sex, income, education, and employment status. These were the findings of a multi-site research study led by Samuel McLean, MD, MPH, associate professor of anesthesiology and emergency medicine at the University of North Carolina School of Medicine.
