At two months of age, infants lack language and fine motor control but their minds may be understanding how things look and figuring out to which category they belong, which would push back earlier beliefs about the foundations of visual cognition.

A new study recruited 130 two-month-old infants who were placed on a beanbag chair wearing sound-canceling headphones, while shown bright, colorful images which kept them engaged for 15-20 minutes. The team used functional MRI (fMRI) to measure changes in brain activity in response to pictures representing 12 common visual categories such as cat, bird, rubber duck, shopping cart and tree.

Opportunistic salpingectomy, proactively removing a person’s fallopian tubes when they are already undergoing a gyecological surgery such as hysterectomy or tubal ligation, may be a way to reduce ovarian cancer risk. Most ovarian cancers originate in the fallopian tubes rather than the ovaries and ovarian cancer is the most lethal gynecological cancer.

Existing treatments control HIV but the immune system does not revert to normal. They is why people living with HIV remain susceptible to infections and it underscores the need for immunotherapies.

That requires modern tools like CRISPR-Cas9 and others. Tools that environmentalists oppose, insisting all science is a corporate conspiracy. As they have historically done with natural gas and GMOs and vaccines. Antiretroviral therapy is highly effective at suppressing HIV, so the virus is no longer the direct death sentence it once was, but the immune system remains in an inflammatory state of overactivation and impaired functionality.

In older countries it has become common for young people to live with their parents until, and sometimes well after, they get married. 

A new study finds that some parts of the animal kingdom don't even stop growing until what it middle age for humans. An analysis of 17 tyrannosaurus rex specimens, from early juveniles to older adults, concludes they took 40 years to reach their full size of around eight tons.

Colorectal cancer, cancer of the colon and rectum, is the third most common form of cancer in the world and has the second highest mortality rate. When caught early enough, it is usually treated with surgery, radiation or chemotherapy, methods that can have significant side effects.

A new study highlights a fourth way, one the researchers hope could have fewer side effects. They found that a purified toxin secreted by cholera bacteria can slow the growth of colorectal cancer and has not shown any side effects. It worked by  changing the immune microenvironment in tumors.

Diabetic foot infections are a serious complications of diabetes and a leading cause of lower-limb amputation but little is known about the specific pathogens involved in these chronic foot infections, particularly E. coli, despite its frequent detection in clinical samples.

A new genomic characterization of E. coli strains isolated directly from diabetic foot ulcers across multiple continents may help explain why some infections become difficult to treat and lead to severe, even life-threatening, outcomes. The team analyzed whole-genome sequences from 42 E. coli strains isolated from infected diabetic foot ulcers in patients from Europe, Africa, Asia, and the Americas and sequenced the complete DNA of each bacterial strain.
