Lemon trees showed less response to citrus greening disease pathogen than orange trees
Citrus greening disease was first discovered in Florida in 2005. Since then, production of oranges in the United States for processing has declined by 72 percent between the 2007-2008 growing season and the 2017-2018 growing season, primarily in Florida. The disease was discovered in California in 2012, and now the state is beginning to see a rapid increase of citrus greening disease.

How imperfect memory causes poor choices
A new study from UC Berkeley's Haas School of Business and UC San Francisco's Department of Neurology combines insights from economics and psychology with decision-making experiments and fMRI brain scans to examine how our imperfect memories affect our decision making. Answering this question could hold implications for everything from conducting consumer research and crafting public policy to managing neurodegenerative diseases.

Elephant seals' extreme diving allows them to exploit deep ocean niche
Using data captured by video cameras and smart accelerometers attached to female elephant seals, Taiki Adachi and colleagues show that the animals spend at least 80% of their day foraging for fish, feeding between 1,000 and 2,000 times per day. The unique glimpse at elephant seal foraging strategy shows how these large marine mammals exploit a unique ocean

The triple threat of coronavirus
Immense research efforts are invested in figuring out how the virus manages to mount an effective invasion while throwing the immune system off course. A new study, published today in Nature, reveals a multipronged strategy that the virus employs to ensure its quick and efficient replication, while avoiding detection by the immune system.

Autologous adipose injection for shoulder pain in wheelchair users with spinal cord injury
Dr. Malanga: "The results show that the minimally invasive injection of micro-fragmented adipose tissue is a safe and efficacious option for wheelchair users with shoulder pain. Based on the success of our study, a randomized controlled study with a larger number of subjects has been initiated in this patient population through funding from the New Jersey Commission for Spinal Cord Research."

Fighting food insecurity by building better beans
As climate change heats up the air and land making them hotter and dryer, warmer nighttime temperatures make it more difficult to grow beans -- the number one source of protein and nutrients for many people living in Central America and Africa. Researchers at Michigan State University are building better beans by tapping into the genetics of the more heat-resistant tepary bean.

Kefir packs less of a probiotic punch than labels claim
Gut health is having a moment, with sales of fermented foods such as kefir, kombucha, and kimchi steadily on the rise. The benefits of "good bacteria" in fermented foods and supplements go well beyond the gut, moderating immune responses, heart health, weight, and even mood. But do products hold up to the claims on their labels?
