Read previewAt 93, John Starbrook competes in water polo games, hits the gym up to twice a day, and only stopped running marathons five years ago. As average life spans rise and an aging population becomes a global reality, interest in staying healthy for longer is growing. But a healthy lifestyle appeared to offset the effects of genes linked to a shorter lifespan by 62%. But he really amped things up at age 53 when he got into running marathons. Research suggests social bonds are an important part of a long, healthy life.

☆ Genes known to increase the risk of Alzheimer’s may actually be an inherited form of the disorder, researchers say
▼ + stars: | 2024-05-06 | by ( Brenda Goodman | ) edition.cnn.com time to read: +10 min

Among people diagnosed with Alzheimer’s, researchers recognize familial forms of the disease and sporadic cases. This shifting appreciation of inherited risk, researchers say, is due to a better understanding of the role of a fourth gene that carries the blueprints to make a lipid-carrying protein called apolipoprotein E, known as APOE. One known as APOE2 is thought to be protective against the development of Alzheimer’s disease. They also compared people with two copies of APOE4 to people with other inherited forms of the disease — early-onset autosomal dominant Alzheimer’s disease (ADAD) and Down syndrome-associated Alzheimer’s disease (DSAD). Gene testing isn’t currently recommendedIt is also likely to change how people who carry the APOE4 gene are diagnosed and treated.

CNN —The use of phrases such as “pregnant people” or “penis owners” in cultural or political discourse is sometimes met with confusion, or even anger. And it’s the most inclusive, streamlined way to refer to everyone who, regardless of their gender identity, has certain anatomy or biological abilities. Using gender-inclusive language can create an environment of acceptance, experts say. READ MORE: Gender identity: The difference between gender, sex and other need-to-knowsHere’s what experts have to say about these linguistic changes and concerns that have been raised.

At the same time, a healthy lifestyle appeared to offset the effects of genes linked to a shorter lifespan by 62%. Making favorable lifestyle choices despite having genes linked to a shorter lifespan was linked to living 5.22 years longer than those who made unfavorable choices. However, she said that the effects of lifestyle factors in the study were notable because they suggest that while we can't change our genes, healthy habits may lessen their impact.

Even humble fruit flies organize themselves into regularly spaced clusters, researchers have found. Within those social networks, certain individuals will often stand out as “gatekeepers,” playing an important role for cohesion and communication within that group. New research published Tuesday in the journal Nature Communications has identified a gene responsible for regulating the structure of social networks in fruit flies. The study opened up new opportunities for exploring the molecular evolution of social networks and collective behavior in other animals.

Individuals with genetic risk could extend their lifespan by up to 5.5 years with a healthy lifestyle, the data showed. “Adherence to a healthy lifestyle could substantially attenuate the lifespan reduction for individuals with genetic susceptibility to a shorter lifespan,” Li said.

The left is not “by nature” unhappy; we are often brutally honest with ourselves and unavoidably empathetic to the plights of those who suffer. If we feel more unhappy these days, it’s not because it’s in our genes. We see it all with clarity and are therefore motivated to change it.

But there is no standard test to detect early cases of pancreatic cancer, before cancer cells have spread and when surgery is more likely to be helpful. But many studies investigating the potential of liquid biopsy tests for the early detection of pancreatic cancer are still in the early phases. The researchers found that their liquid biopsy approach detected 93% of pancreatic cancers among the US volunteers in their study, 91% of pancreatic cancers in the South Korean cohort and 88% of pancreatic cancers in the Chinese cohort. But there is no blood test that can detect early pancreatic cancer. “Smoking is the most important avoidable risk factor for pancreatic cancer,” according to the American Cancer Society.

Poor irrigation practices, such as insufficient water application, using saline water, and not maintaining adequate drainage can also lead to salty soils. Irrigation can drive salinization, especially if farmers are watering their crops with salty water. In this case, that means watering crops with salt water in their lab. Globally, over 3,700 acres — just over four times the size of NYC's Central Park — of farmland grow SaliCrop seeds. Red Sea Farms, for example, is a Saudi Arabian company that uses selective breeding to grow crops that can be irrigated with salt water.

As a medical oncologist, I am heartbroken — but hardly surprised. In fact, it is part of a rising global trend in which newly diagnosed cancer patients are getting younger. The global incidence of early-onset cancer increased by 79.1% and early-onset cancer deaths rose by 27.7% from 1990 to 2019, a 2023 study in the journal BMJ Oncology found. And because early-onset cancers are often diagnosed at advanced stages, they were once thought to be biologically different and more pernicious than their older counterparts. Younger patients may be pregnant at the start of therapy or worry about the effects on fertility.

One of those led to shorter tails; the more of that protein the genes produced, the shorter the tails. A tail as old as timeFor modern humans, tails are a distant genetic memory. While Alu’s role “seems to be a very important one,” other genetic factors likely contributed to the permanent disappearance of our primate ancestors’ tails,” Xia said. In their experiments, the researchers found that when mice were genetically engineered for tail loss, some developed neural tube deformities that resembled spina bifida in humans. “Maybe the reason why we have this condition in humans is because of this trade-off that our ancestors made 25 million years ago to lose their tails,” Yanai said.

Daddy longlegs, the group of splendidly leggy arachnids also known as harvestmen, have been thought to have just two eyes. Arachnids include spiders, scorpions, harvestmen and other arthropods, and divining the relationships among this sprawling group of organisms is tricky. For the current study, Dr. Gainett used fluorescent tags to study the development of harvestman eyes. These findings suggest that the neural architecture that handles the daddy longlegs’ vision may be quite old.
