Delays in cancer diagnosis for pregnant women

Cancer symptoms can sometimes be misdiagnosed as normal pregnancy-related changes for women who are expecting, in some cases leading to a delay in treatment, according to a new study.

Artificial intelligence improves personalized cancer treatment

Personalized medicine aims to tailor treatments to individual patients. Until now, this has been done using a small number of parameters to predict the course of a disease. However, these few parameters are often not enough to understand the complexity of diseases such as cancer. A team of researchers has developed a new approach to this problem using artificial intelligence (AI).

Wildfire smoke can carry toxins hundreds of kilometers, depositing grime on urban structures, surfaces

Researchers have shown that plumes of wildfire smoke can carry contaminants hundreds of kilometers, leaving a toxic and lingering footprint which has the potential to be re-released into the environment.

New avenues in quantum research: Supramolecular qubit candidates detected

Researchers were able to demonstrate for the first time that non-covalent bonds between spin centers are also capable of producing quartet states through spin mixing. Supramolecular chemistry is thus a valuable tool for the research, development and scaling of new materials for quantum technologies.

New structures of a critical amyloid protein illuminated

The tiny protein known as transthyretin can cause big problems in the body when it misfolds after secretion. While healthy transthyretin moves hormones through blood and spinal fluid, misfolded versions of the protein form dangerous clumps in the heart and along nerves -- triggering a progressive and fatal disease known as transthyretin amyloidosis (ATTR). Up to a quarter of all men over the age of 80 have some degree of ATTR, which can cause shortness of breath, dizziness and tingling or loss of sensation in the extremities. Now, scientists have uncovered new structures of transthyretin.

Calorie labels on menus could make eating disorders worse

Calorie labels on restaurant menus are negatively impacting people with eating disorders, according to a new study. The review found that individuals who have been diagnosed with an eating disorder changed their behaviors if presented with a menu featuring calorie labels.

Explaining persistent hydrogen in Mars' atmosphere

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, researchers think they have a good explanation for a warmer, wetter ancient Mars. Building on prior theories describing the Mars of yore as a hot again, cold again place, a team has determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.
