- Lycopene, the red pigment in tomatoes, may offer modest protection against cancer and cancer-related death.
- A meta-analysis of 121 studies found high lycopene intake linked to a 5% lower cancer risk, while tomato consumption was tied to an 11% lower risk of cancer death and lycopene intake specifically to a 16% lower risk.
- Blood lycopene levels showed stronger protection, with an 11% lower cancer risk and 24% lower risk of cancer death.
- Benefits peak at 5 to 8 milligrams of lycopene daily, roughly one to two medium tomatoes.
- Cooking tomatoes with healthy fats like olive oil significantly improves lycopene absorption.
Daily routines reduce pain and depression in older adults
University of Missouri researchers have identified a simple, effective way to improve quality of life. A new study found that maintaining a consistent daily routine can reduce physical pain and ease symptoms of depression, demonstrating how everyday habits can have a meaningful impact on well-being, particularly for older adults with insomnia.
Roughly half of adults age 60 and older report experiencing insomnia symptoms. To better understand how insomnia affects overall well-being, researchers analyzed survey data from 67 older adults, including 37 people with insomnia.
As expected, participants with insomnia reported higher levels of pain and depression. Participants who maintained consistent daily routines tended to report lower levels of pain and depression, a relationship that may be explained in part by the way regular schedules help synchronize the body's internal clock.
Those daily habits help regulate the body's circadian rhythm that influences sleep, mood and other biological functions. Even small disruptions to daily schedules can throw off the body's internal clock, a phenomenon sometimes referred to as social jet lag.
When nature not only restores, but fortifies
Max Planck Institute for Human Development (Germany), July 29 2026 (Eurekalert)
A walk in the park after a stressful day is a classic example of how nature can help people switch off and unwind. But natural environments may offer even more: enhancing mood and cognitive performance even when a person was not previously stressed or depleted. This is the finding of a review article published in the Journal of Environmental Psychology by researchers from the Max Planck Institute for Human Development.
For the review, the researchers evaluated 54 studies that comprised 61 experiments examining the effect on natural and urban environments on cognitive performance, affect or subjective sense of relaxation.
- Focus on restoration: For decades, research has primarily examined how nature helps people recover from stress or mental strain.
- Overlooked ‘instorative’ effects: Nature may also promote attention, positive affect and well-being even without prior depletion.
- Positive findings: Despite their small number, all instorative studies reported improvements in attention, affect or subjective well-being.
- Implications for daily life: The results suggest that green spaces not only contribute to restoration after depletion but may also promote concentration, resilience and mental health in everyday life.
Skin Damage May Begin Long Before You Can See It
Skin can appear structurally intact even as the collagen beneath it begins losing its internal organization. An international research team led by Hiroshima University found that the molecular arrangement and supramolecular chirality—or structural handedness—of dermal collagen deteriorate before its fiber network begins to thin or fragment.
Collagen supports the skin through a carefully organized hierarchy that extends from molecules to larger fibers. This arrangement gives tissue much of its structure and mechanical strength.
To identify changes that ordinary imaging could not detect, the researchers combined advanced optical imaging with chiroptical spectroscopy, a method that measures how structures with a particular handedness interact with light. They researchers examined collagen abundance and the coherence of its chiral organization within the same physical section of tissue.
The measurements revealed that collagen quantity and collagen organization do not necessarily decline together. Tissue samples could retain much of their overall collagen coverage and mass even after the coherence of their supramolecular chirality had deteriorated substantially.
In other words, the visible fiber network could still appear largely intact while its internal order was already breaking down. That separation suggests that collagen deterioration begins at smaller structural scales before becoming obvious through changes in fiber shape or abundance.
According to the study, researchers tracked 76 British adults over eight days, monitoring their activity levels and sleep patterns while administering daily cognitive tests.
The study found that for every additional 30 minutes of moderate-to-vigorous physical activity, participants performed better on tests of episodic memory and working memory the following day. Episodic memory involves recalling personal experiences, while working memory holds information temporarily for decision-making. Light activity showed weaker effects, and sedentary time was not associated with cognitive benefits, according to the researchers.
The study classified activity into three categories: sedentary, light and moderate-to-vigorous. The moderate-to-vigorous category included brisk walking, running, cycling and resistance training. Light activity showed weaker benefits, and sedentary behavior was associated with no improvement, the researchers said.
The study also examined the contribution of sleep. For every extra 30 minutes of REM or deep sleep, participants showed improvements in memory and attention span the following day, the researchers said.
