Research reveals stronger people have healthier brains - A study of nearly half a million people has revealed that muscular strength, measured by handgrip, is an indication of how healthy our brains are. This finding exists in the general population as well as people experiencing schizophrenia.
Blood-red ants of the species Formica sanguinea are known for instituting a system of slavery. They infiltrate the nest of another ant species, assassinate the queen, and kidnap the pupae to raise as the next generation of slaves. New research sheds light on the evolution of this behavior.
More people have died or been injured in mass school shootings in the United States in the past 18 years than in the entire 20th century. In a new study, researchers have reviewed the history of mass school shootings in the U.S.
For brown widow spiders, sex is literally a matter of life and death. If a male chooses an adult female, chances are roughly 50/50 that she’ll eat him afterward. But if he mates with a younger subadult female, she’ll let him live to see another day. Despite this, the males prefer older mates.
Study finds menstrual cups be have greater risk of toxic shock syndrome versus current tampon brands due to air being inserted along with cup and biofilm surviving rinsing. Recommendations to reduce risk are to use a second cup and boil between uses.
Malaria infection creates a ‘human perfume’ that makes us more attractive to mosquitoes; may help to explain why the disease is able to spread so effectively.
A new study found poorer childhood cognition occurred when pregnant women or their offspring consumed greater quantities of sugar. Substituting with diet soda during pregnancy also appeared to have negative effects. However, children’s fruit consumption was associated with higher cognitive scores.
Eating too much sugar during pregnancy could affect your child's intelligence and memory, a new study has found. The study found that consuming greater quantities of sugar was associated with poorer cognition in their children, including poorer problem-solving abilities, poorer verbal memory
Humans and chimpanzees recently evolved a more active fight-or-flight response compared to other primates, possibly in response to the threat of warfare, finds a new study. Macaques and some bonobos lack these genetic variants that may increase the fight-or-flight response.
Reddit can help people suffering from depression, bipolar disorder, and schizophrenia improve their written communication and express their ideas (paper in JMIR)
Older adults who take a novel antioxidant that specifically targets cellular powerhouses, or mitochondria, see aging of their blood vessels reverse by the equivalent of 15 to 20 years within six weeks, according to new research.
Childhood poverty costs U.S. $1.03 trillion in a year, study finds. Total amounts to 28% of the federal budget.
New form of DNA, known as 'i-motif' structures, discovered within living human cells. Scientists suspect it is involved with the process of “reading” DNA sequences and converting them into useful substances.
The brain doesn't care about being perfect - The psychology of perfectionism makes you feel meaningless, leading to self-doubt, perceived failure, and lack of confidence. The solution, research says, is to apply top-down "frame shifts."
Hunger is a Gatekeeper of Pain in the Brain: Hunger-mediating neurons suppress long-term inflammatory pain, but acute pain, which signals an immediate threat, dampens the activity of these neurons and thus deprioritizes feeding.
When endangered killer whales swim through the sheltered waters of Puget Sound, they leave behind traces of "environmental DNA" that researchers can detect as much as two hours later, a new study has found.

Coal plant emissions damage infant DNA, a new study shows - A study from Columbia University has found that babies born during a coal plant’s operation in China had shorter telomeres than those born after the plant’s closure.
Researchers have implanted a bean-sized brain organoid into a mouse. This approach advances the organoid research so that it could be used to treat humans - by successfully growing them in lab animals, they can better understand how the human brain develops - both normally and when illnesses occur

Adding radish, rocket or rape seed sprouts (but not mustard) to broccoli sprouts increased sulforaphane by about 2x, while decreasing sulforaphane nitrile
Fat cells can be damaged in a short amount of time when they are exposed to the fatty acid palmitate or the hormone TNF-alpha through a fatty diet, a new study shows. The researchers hope this new knowledge may be used to develop new preventive strategies for diabetes.
Having patients recovering from surgery self-report their pain via a specially designed tablet app called "PainPad" was more effective than data collected by nurses
Found: a new form of DNA in our cells
New study shows that specific T-cells residing in fat tissue regulate body temperature. Mice lacking these immune cells were unable to regulate their body temperature after cold challenge.

Why psychopaths make such bad first impressions - New research shows why psychopaths fail the first impression test. The results paint a negative picture of interpersonal interactions with individuals scoring highly on any Dark Tetrad traits (psychopathy, Machiavellianism, narcissism, and sadism).
The science of FOMO reveals the truth of what we're really missing out on (and how it hurts out psychological state and mental functioning).
Scientists at the University of Maryland School of Medicine have for the first time found direct causal links between the neurotransmitter dopamine and avoidance – behavior related to pain and fear.
Increased Risk of Psychiatric Disorders in Allergic Diseases: A Nationwide, Population-Based, Cohort Study
2 Jajaninetynine Here you go: Small amounts of alcohol are well known to be seemingly protective against heart disease in some studies, whereas heavy, chronic alcohol use can have detrimental effects on the liver as well as on the cardiovascular system,” says Zachary Kaminsky, Ph.D., assistant professor of psychiatry and behavioral sciences. “Regulation of PCSK9 seems to correlate with this pattern and may be a significant underlying factor behind the variations in the relationship between cholesterol and cardiovascular disease when it comes to alcohol use.
