200-year old poop shows rural elites in New England had parasitic infections
In the early 19th century in North America, parasitic infections were quite common in urban areas due in part to population growth and urbanization. Prior research has found that poor sanitation, unsanitary privy (outhouse) conditions, and increased.....»»
How meningitis-causing bacteria may sense fever to avoid immune killing
Researchers have discovered a mechanism through which meningitis-causing bacteria can evade our immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to increasing temperatures by producing sa.....»»
Brazilian coronavirus variant likely to be more transmissible and able to evade immunity, study finds
A new study indicates that the coronavirus variant called P.1, which originated in Brazil, could pose a bigger threat than previously assumed. The researchers conclude that it is likely that P.1 is more transmissible than other strains of SARS-Cov2 a.....»»
Study shows how meningitis-causing bacteria may sense fever to avoid immune killing
Researchers at Karolinska Institutet in Sweden have discovered a mechanism through which meningitis-causing bacteria can evade the immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to incr.....»»

SARS-CoV-2 variants from mink evade inhibition by antibodies
It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry.....»»
Cancer cells may evade chemotherapy by going dormant
Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of 'active hibernation' that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according.....»»
The skeleton of the malaria parasite reveals its secrets
Plasmodium is the parasite causing malaria, one of the deadliest parasitic diseases. The parasite requires two hosts —the Anopheles mosquito and the human— to complete its life cycle and goes through different forms at each stage of its life cycl.....»»
New evidence COVID-19 antibodies, vaccines less effective against variants
New research has found that new variants of the virus that causes COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic, potentially undermining the effectiveness of vaccines and antibody-based drugs.....»»

How SARS-CoV-2"s sugar-coated shield helps activate the virus
SARS-CoV-2, the virus that causes COVID-19, is coated with sugars called glycans, which help it evade the immune system. New research shows precisely how those sugars help the virus become activated and infectious and could help with vaccine and drug.....»»
