Shanghai Lanjian Hongqing Technology Company, also known as Hongqing Technology, filed an Advance Publication Information (API) with the International Telecommunication Union (ITU) May 24.  The filing outlines plans for a constellation

An eosinophil immune cell, which can be involved in asthma KATERYNA KON/SCIENCE PHOTO LIBRARY/Alamy It might be possible to effectively cure the most common form of asthma by using genetically engineered cells to kill off the rogue immune cells that trigger asthma attacks, a study in mice suggests. But making this kind of treatment affordable

HELSINKI — China’s experimental reusable spacecraft has released an unknown object into orbit while conducting its third mission. U.S. Space Force space domain awareness teams cataloged the object as 59884 (International designator 2023-195G). The suspected spaceplane launched Dec. 14, 2023 and has been in orbit 164 days. The object appears to have been released May

Mice that were given a high dose of the antiviral drug oseltamivir phosphate, better known as Tamiflu, after prolonged and excessive noise exposure showed fewer signs of hearing loss compared with those not given the medication Read the original article here

WASHINGTON — The U.S. Space Force is soliciting bids from commercial satellite manufacturers for a 10-year procurement of small satellites to carry experimental payloads to space. The Space Test Program office on May 23 issued its final request for proposals for the Space Test Experiments Platform (STEP) 2.0 contract — an indefinite delivery/indefinite quantity (IDIQ)

Ants that drink a caffeinated solution can locate sweet rewards faster than un-caffeinated ants, suggesting the drug boosts learning. To see how Argentine ants (Linepithema humile) respond to caffeine, researchers created an ant-sized arena on a sheet of printer paper in the lab. They then placed a drop of sugary solution on the paper for
