A bad liver today currently means a replacement, but having enough transplant organs is challenging when families worry their loved ones' skeletons could be sold to middle schools and end up immortalized in prank photos. The future will involve replacements made with a patient's own stem cells, no immunosuppressive drugs or waiting lists needed.

Once the weather got political, more attention became focused on the cyclical climate phenomenon El Niño. Critics charged that too many early models were shaped by understating its effects while proponents insisted its efforts were worse due to CO2 emissions.

There is something for everyone. It is cyclical, but not predictable, because it might bring wetter conditions to some areas and drier to others every two years. Or every seven. Experts can't agree on when it begins or ends, only that it's impacted by changes in what ancient sailors called the trade winds - the air currents that moved cargo ships from from east to west along the equator.

Glioblastoma, a deadly brain cancer, is treated with surgery to remove as much of the tumor as possible and then radiation and chemotherapy.

Like all cancer, that may not be the end of it. Sometimes, the aggressive cancer returns. A recent study sought to find out if high doses of vitamin B3 or niacin could help, by rejuvenating compromised immune cells to kill tumor cells, the way it had with mice. The researchers found that while glioblastoma suppresses the immune system, niacin in mice gave immune cells a boost so they could continue to attack and destroy cancer cells.

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.
