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…

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…

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.

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…

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…

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…

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…

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…

A temperature reconstruction from ice cores of the past 1,000 years reveals that today’s warming in central-north Greenland is surprisingly pronounced. The most recent decade surveyed in a study, the years 2001 to 2011, was the warmest in the past 1,00…

Scientists have developed a revolutionary new method for capturing high-resolution images of fluctuations in materials at the nanoscale using powerful X-ray sources. The technique, which they call Coherent Correlation Imaging (CCI), allows for the crea…

Given the choice of three different ‘spin’ orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher, appear to have a preference. Recent results reveal a preference in global spin alignment…

Physicists have developed a protocol to verify the accuracy of quantum experiments.

Engineers fabricated 2D materials that could lead to next-generation transistors and electronic films.

The quantum nature of objects visible to the naked eye is currently a much-discussed research question. A team has now demonstrated a new method in the laboratory that could make the quantum properties of macroscopic objects more accessible than before…

A new study shows that North American bird communities containing functionally diverse species have changed less under climate change during the past 50 years than functionally simple communities.

Eating disorders are stereotypically associated with adolescents and young adults. Growing evidence, however, suggests that these conditions can occur at any time during a woman’s lifespan, including at midlife. A new study finds that body dissatisfact…

Glioblastoma (GBM) is a WHO grade IV brain tumor with dismal prognosis. Although post-surgical radiation chemotherapy combined with temozolomide is the standard line of treatment, GBM cells surviving radiotherapy contribute to tumor progression and rec…

A team of mathematicians and pharmaceutical scientists collaborated to identify the major cause of the low accuracy of the equation in the FDA guidance used to predict drug-drug interaction through an enzyme (cytochrome P450, CYP) induction mediation. …

Timing from first meal to last meal was not associated with weight loss in a six-year study: Eating less overall and fewer large meals may be a more effective weight management strategy than restricting meals to a narrow time window, such as intermitte…

A tendency for one or both spouses to avoid or withdraw from tough conversations could set up married couples for emotional distress, bad feelings about their relationship, chronic inflammation and lowered immune function, new research suggests.
