Experimental HIV vaccine regimen safe but ineffective
An investigational HIV vaccine regimen tested among men who have sex with men (MSM) and transgender people was safe but did not provide protection against HIV acquisition, an independent data and safety monitoring board (DSMB) has determined. The HPX30…
Revealing the thermal heat dance of magnetic domains
Everyone knows that holding two magnets together will lead to one of two results: they stick together, or they push each other apart. From this perspective, magnetism seems simple, but scientists have struggled for decades to really understand how magn…
Simple laser treatments may help prevent nonmelanoma skin cancer
In a study of patients with a history of facial keratinocyte carcinoma, 20.9% of those treated with nonablative fractional lasers experienced a subsequent keratinocyte carcinoma, compared with 40.4% of patients who did not receive laser treatment.
Researchers uncover secrets on how Alaska’s Denali Fault formed
New findings begin to fill major gaps in understanding about how geological faults behave and appear as they deepen, and they could eventually help lead future researchers to develop better earthquake models on strike-slip faults, regions with frequent…
What’s driving re-burns across California and the West?
Seasonal temperature, moisture loss from plants and wind speed are what primarily drive fires that sweep across the same landscape multiple times, a new study reveals. These findings and others could help land managers plan more effective treatments in…
The dark cost of being toxic
Scientists have discovered that the striking orange and black wings of monarch butterflies not only send the message to predators that these butterflies are highly toxic, but that the storage of toxins and development of the colorful wings come at a co…
Early tastings shorten breastfeeding
The earlier infants begin to taste small samples of solid food, the earlier they eat more food and stop breastfeeding. This is shown in a new study, in which the mothers of 1,251 infants from all over Sweden participated. Almost half of the infants rec…
The rich meteorology of Mars studied in detail from the Perseverance rover
Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and daily cycles of temperature and pressure, as well as t…
