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.

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.

Government unemployment data today are what Nielsen TV ratings were decades ago - a flawed metric only believed if you like what they show. Government unemployment data take too long, like the CDC for the last 15 years needs six weeks to tell the public if lettuce has E. coli, and it only measures people getting paid through unemployment insurance. Once that runs out, to the government they are suddenly employed again.

Gestational diabetes, a form of glucose intolerance during pregnancy, occurs primarily in women who already had obesity and added more weight. It not only carries immediate pregnancy risks but increases the chance of future heart disease for both the mother and the child. And it has gone up every year since 2016, according a new analysis of more than 12 million U.S. births from the National Center for Health Statistics; up 36 percent during the study period. Pregnancy is simply a trigger for something likely to happen eventually, due to poor energy balance among more women. They eat far more than they burn with exercise, which leads to weight gain and risks of many lifestyle diseases only exceeded by alcohol and cigarettes.

Researchers recently studied the relationship between numerical information in our vision, and how it affects our perception of space - and discovered subtle asymmetries that color our view on the world. They wanted to see if numbers in our vision create “attentional biases” so volunteers were asked to identify the center of lines and squares filled with numbers. It showed how our perception of space is a complex interplay between “object-based” processing and our processing of numerical information.

Bees have the reputation of being incredibly organized and spending their days making sure our food ecosystem is functioning. Neither is accurate. Unless you are an almond farmer in California and rented bees that were delivered in giant trucks, they have no impact on your food, and they are also not working non-stop for the hive.Instead, they may be genetically wired to beg for food.Male bees -“drones” - actually cannot digest pollen, the most important source of protein for bees. To avoid starvation, they depend on worker bees feeding them a pre-processed paste that workers make from pollen. It's not a communist love-fest, though, drones instead must convince workers to provide the food. Over time, they evolved to be able to beg.

Bleeding hosts and stigmatizations are the best-known medieval miracles but less known ones, like a scorched cherry twig miraculously sprouting, a diseased swamp becoming fertile land, and healing the broken leg of an ox, are getting a new look.
