No safety in numbers for moths and butterflies
May 10 | News
Scientists at the University of Leeds are to investigate how lethal viruses attack differently sized populations of moths and butterflies in research that may help develop new methods of pest control.
Insight into HIV Immunity May Lead to Vaccine
May 9 | News
By investigating the action of the human antibodies called ADCC, in people with HIV, researchers were able to identify that the virus evolves to evade or ‘escape’ the antibodies.
Study Reveals When Cattle Can Transmit Foot-and-Mouth Disease
May 6 | News
A new study of foot-and-mouth disease shows that cattle afflicted with the virus are only infectious for a brief window of time—about half as long as previously thought. This finding suggests that the controversial control measures used to halt the disease’s spread, such as killing large numbers of livestock, could be reduced.
Antibodies Help Protect Monkeys from HIV-Like Virus
May 6 | News
Using a monkey model of AIDS, scientists have identified a vaccine-generated immune-system response that correlates with protection against infection by the monkey version of HIV, called simian immunodeficiency virus (SIV). The researchers found that neutralizing antibodies generated by immunization were associated with protection against SIV infection.
Scientists Paint Chemical Picture of Antibiotic-resistant Bacteria
Apr 29 | News
Scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing compounds to prevent infections by recently evolved, drug-resistant "superbugs" that often are found in hospitals, as well as in the general population.
Genes Causing Antimalarial Drug Resistance Identified
Apr 22 | News
Researchers have identified several genes that may be implicated in the malaria parasite’s ability to evade drug treatments. Further testing revealed that one of the genes, when inserted into drug-sensitive parasites, rendered them less vulnerable to three antimalarial drugs.
Researchers Identify Cause and New Treatment for Common Recurrent Fever in Children
Apr 12 | News
A preliminary study conducted by a team at the National Institutes of Health has identified a promising new treatment in children for the most common periodic fever disease in children. The syndrome is called periodic fever associated with aphthous stomatitis, pharyngitis and cervical adenitis — or PFAPA — and is characterized by monthly flare-ups of fever, accompanied by sore throat, swollen glands and mouth lesions.
Wild Birds May Play a Role in the Spread of Bird Flu
Mar 24 | News
Wild migratory birds may indeed play a role in the spread of bird flu, also known as highly pathogenic avian influenza H5N1. A study by the U.S. Geological Survey, the United Nations Food and Agriculture Organization and the Chinese Academy of Sciences used satellites, outbreak data and genetics to uncover an unknown link in Tibet among wild birds, poultry and the movement of the often-deadly virus.
