Thanks to the fall armyworm, nearly all of Africa's maize crop is in jeopardy, finds a new study. 

The new projection was made using 3,175 geo-tagged occurrences and factoring in physiological and climatological requirements to geographically assess its range. They showed that almost 92 percent of Africa’s maize growing areas can mean year-round growth of fall armyworm while 95 percent are suitable for that plus pests like the maize stalk borer, Western corn rootworm and Asiatic witchweed.

Despite apparent beliefs on social media today, the modern anti-vaccine movement did not begin with the COVID-19 vaccine in 2021. For decades prior to that, wealthy elites who believed that supplements and organic food were medicine led the world in denying their children vaccines.

Reducing the risk of transfusion-transmitted HIV from blood donations is important for public health and the U.S. currently uses time-based deferrals to assess donor eligibility. Now the FDA is proposing individual risk-based questions to reduce the risk of transfusion-transmitted HIV similar to policies in place in countries like the United Kingdom and Canada.

Blood donations are important and FDA believes the implementation of the proposed individual risk-based questions will not compromise the safety or availability of the blood supply. The new draft recommendations are based on data from other countries with similar HIV epidemiology that have instituted this approach, as well as ongoing surveillance of the U.S. blood supply.

Food is not medicine, anyone claiming it is medicine is selling you something, like a diet plan, but nutrients can impact cancer cells.

How that applies consistently is unknown so a new tool hopes to create an exploratory method using mice. Mice don't translate well to humans, they are not little people, but they can exclude effects in humans and that has value also. 

IN 1994, President Bill Clinton and Senator Tom Harkin set off a supplement boom - by decreeing that supplements could be exempt from real FDA oversight as long as they didn't claim to cure cancer or kill anyone (which companies in that market continued to do anyway) and placed in small print that their supernatural claims were not validated by FDA.

That, plus wasting taxpayer money at the National Center for Complementary and Alternative Medicine(1) that could have gone to real research created a boom, to where woo and mysticism that claims it is sticking it to Big Pharma is a $40 billion per year industry.

Too often mental health problems are dismissed as being “all in your head”. With scientific and medical advancements showing mental illness can cause physical changes to the body, we now know the devastating impact mental health has on physical health.

One system that is greatly affected by mental health is the cardiovascular system. Unfortunately, not only is there a link between mental illness and cardiovascular disease, it’s a connection that runs both ways.

Mental Health is Heart Health

Sudden infant death syndrome (SIDS) is a diagnosis of exclusion, a general term for death during the first year of life that lacks an obvious cause.

Though it is a leading cause of death, its etiology is complex and remains largely unknown so assumptions are things like sleeping in a dangerous position, a general failure during the critical development period, or an unknown underlying biological vulnerability.

Many parents say they are worried about the negative effects of screen time on children. Too much of anything can have negative effects, from books to music to TV, but the solution is to impose diversity so they eventually enjoy different activities.

The screen time problem got even worse due to government lockdowns imposed during the COVID-19 pandemic. Rather than wear masks in a park, it generally led to more screen time and less outdoor time for children. 

Empathy is critical to having supportive conversations about mental health. But this skill can be tricky to learn, especially in the moment when a person is sharing something hard. 

Yesterday I visited a high school in Venice to deliver a lecture on particle physics, and to invite the participating students to take part in an art and science contest. This is part of the INFN "Art and Science across Italy" project, which has reached its fourth edition, organizes art exhibits with the students' creations in several cities across Italy. The best works are then selected for a final exhibit in Naples, and the 24 winners are offered a week-long visit to the CERN laboratories in Geneva, Switzerland.
