認知老化に関するほとんどの研究は、ある時点の経済的困難のみを対象としています。数十年分のデータを用いた私たちの研究により、時折起こる逆境ではなく、長年にわたる困難の蓄積が最悪の認知的健康結果に関係していることがわかりました。 ” Men who experienced persistent economic adversity performed worse on cognitive tests than women at age 53.この違いの理由として考えられるのは、恵まれない男性は恵まれない女性よりも健康行動（喫煙やアルコール乱用など）が悪い可能性があること、特に男性は1946年生まれのこの集団では主な稼ぎ手だったため、経済的逆境のストレスをより多く経験している可能性があることなどだろう。 経済的困難は、人々が収入を管理するのが難しいと感じたかどうか、請求書の支払いに苦労したかどうかなどの質問を使用して評価されました。参加者は、36 歳から 53 歳までの間に少なくとも 2 回、アンケートで閾値を超えるスコアを記録した場合、持続的な困難を経験していると分類されました。 This represented 12% of participants (approximately 1 in 8). sauce: others.

Crop production faces threats from plant pathogens. Traditional disease resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to specific pathogens. However, rapidly evolving pathogens often overcome these natural defenses, and the limited diversity of naturally occurring immune receptors complicates the development of durable resistant crops. Now, a team led by Professor GAO Caixia from the Institute of Genetics and Developmental Biology (IGDB), Chinese Academy of Sciences, has developed a programmable platform for on-demand engineering of synthetic plant immune receptors (SPIRs) that recognize proteins from diverse plant pathogens. This study was published online science July…

In the late 1990s, scientists working in the Ajimu area of ​​Oita Prefecture, Japan, discovered three fossil vertebrae from a giant salamander. Cryptodactylidae family. The bones were preserved in the Rusukawa Formation, a layer of ancient lake sediment from the Pliocene epoch, about 3.5 million years ago. Other fossils found in the same formation include animals such as elephants and crocodiles that no longer live in Japan. These ruins indicate a time when the area was much warmer and wetter than it is today. Researchers initially classified the Ajimuin fossil as a member of the genus Ajimuin. andriascontains the largest…

Lawmakers frequently propose bills named after victims of tragic events to garner public support and commemorate those who died. A recent study assesses whether reading these personal stories leads voters to support bills they might otherwise have doubts about. This result shows that attaching victims’ stories to bills reliably increases voter support. This particular study was recently published in Psychology, Public Policy, and Law. Naming laws after individuals is a common practice in American politics at both the state and federal levels. National registries and local safety mandates are often proposed in response to highly publicized tragedies. Legal scholars have…

Recent research published in translational psychiatry The chemical composition of blood in newborn babies’ umbilical cords may provide early clues about their likelihood of developing diseases such as autism and ADHD, the researchers suggest. By analyzing specific molecules related to cholesterol and amino acids, scientists discovered patterns that evidence increased risk due to these developmental differences years before symptoms typically appear. The findings point to a future in which a simple blood test at birth could help identify children who may benefit from early support and intervention. Childhood-onset neurodevelopmental disorders affect up to one in five children worldwide. These conditions…

Lizzy leads STAT’s FDA coverage. Her story explores the relationship between politics and science at the FDA, its influence on industry, and the agency’s ability to protect and promote public health. Sensitive information can be sent on Signal at lizzylaw.53.In a victory for peptide advocates and Health Secretary Robert F. Kennedy Jr., an advisory committee to the Food and Drug Administration recommended Thursday that compounding pharmacies be allowed to manufacture the drugs BPC-157, KPV, TB-500, and MOTS-c. The FDA committee is scheduled to vote on additional compounds on Friday. The vote is non-binding, and the FDA will ultimately decide whether…

As global temperatures continue to rise, heat waves pose a growing threat to human mental health and emotional well-being. Recent reviews published in magazines american psychologist suggest that rising temperatures can worsen pre-existing psychiatric conditions, increase aggressive behavior, and impair basic cognitive functions. The findings suggest that climate change poses widespread risks to the nervous system, even affecting people who did not previously have the psychological condition. Extreme heat is already recognized as a leading cause of weather-related deaths, usually due to physical emergencies such as heat stroke and cardiovascular failure. Conversations about climate change regularly focus on these physical…

A naturalistic study using speed-dating data found that people who believed they were viewed favorably by others reported stronger romantic feelings. In contrast, people who underestimated how favorably others viewed them reported lower romantic feelings. However, accuracy was more important than optimism when it came to attracting a partner. People who accurately guessed how others saw them received more romantic interest in return. The paper was published in. Personality and Social Psychology Bulletin. In the first moment of meeting someone, a person forms an impression not only of the other person, but also of how they themselves are perceived. These…

The main pillar of cancer immunotherapy involves stimulating the immune system’s specialized killers, T cells, to attack tumors. However, this strategy has been undermined by the tendency of T cells to become exhausted before finishing their job. When cells reach a phase of exhaustion (called T-cell exhaustion), these immune cells lose their ability to sustain attacks and control cancer growth. This is a major problem with checkpoint inhibitors, a type of immunotherapy that releases the brakes on T cells and kickstarts their activity. “The tragic part of T-cell depletion is that immunotherapy may seem to be working for a patient,…

Federal health officials are investigating a new outbreak involving the diarrhea-causing parasite Cyclospora. As of Wednesday, there were 72 people infected. FDA continues to focus on lettuce suppliers as sources of parasites despite flawed test results The Food and Drug Administration has not yet determined which products are linked to the illness. Authorities also have not disclosed the location of the infected person. The Associated Press has asked the FDA for more information. Federal officials said earlier this week that they remained focused on lettuce from Taylor Farms, another source of outbreaks in multiple states. The company announced last week…
