Cigarette butts are the most common form of litter on the planet: 4.5 trillion are littered each year. New research shows that they severely impact plant growth. The presence of cigarette butts reduced root biomass by 57%; germination success by 27%; and shoot length by 28%.
New drug-delivery system disguises chemotherapy drugs as fat, fooling quick-growing and hungry tumor cells that consume the nutrients much faster than normal cells. The drug then activates, suppressing tumor growth. The drug also is lower in toxicity than current drugs, leading to fewer side effects
Many of the deadliest cancers receive the least amount of research funding, finds a new study. ‘Embarrassing’ or stigmatized cancers like lung and liver are underfunded. In contrast, breast cancer and pediatric cancers were all well-funded, respective to their impact on society.
Study finds there were substantial health benefits gained from reductions in coal power plant emissions from 2005-2012.
This oven was used to make bread—thousands of years before agriculture Hunter-gatherers from the Natufian culture baked an early form of bread in this 14,000-year-old fireplace in northeastern Jordan.
Study finds drug resistant infections were linked to unsterile procedures using Bayer medical device and advises infections may be more common than previously recognized
Cleaning our water with 'bioinspired' chemistry: Scientists develop powerful, safe and inexpensive oxidation catalysts inspired by biological processes within us that break down stubborn micropollutants, including pesticides, medications and household cleaners, many of which end up in our waterways.
Orangutan mothers use loud scratches to tell their infants that it is time to leave one area and move to another, possibly to avoid attracting predators or other orangutans.
About 1 in 20 patients is a victim of preventable medical errors, and 12% of such cases result in permanent disability or death. Preventable harm results in about $9.3 billion in extra health care costs in the US. Reducing preventable harm could lead to better care and cost savings for health.
Supermassive Black Hole Imaged by the Event Horizon Telescope Can Constrain Superlight Dark Matter
Good home learning in early years boosts secondary school achievements, according to a new study. This research shows pre-schoolers whose parents regularly read and talked about books with them scored better on math tests at age 12.
A massive new report on Jupiter’s moon Io shows that the explosive world is even stranger than anyone expected. Volcanoes don’t seem to be in the right places, the brightest eruptions seem largely confined to just one hemisphere, and Loki Patera steadfastly refuses to play by anyone’s rules.
Major U.S. cities are leaking methane at twice the rate previously believed. Analyses suggest the five biggest urban areas studied—which together include about 12% of the nation’s population—emit about 890,000 tons of methane each year
The most statistically-powerful study on autism to date has confirmed that the disorder is strongly heritable. The analysis found that over 80% of autism risk is associated with inherited genetic factors.
Antidepressants Reduce Death by One-Third in Diabetic Patients. Researchers add that 50 percent to 75 percent of people with diabetes and depression go undiagnosed, despite therapy and medicine being very effective.
Karaoke-Sleep Study Links Disrupted REM With Poor Memory Processing: An unusual experiment suggests that interrupted REM sleep can interfere with the amygdala’s ability to process emotional memories overnight—in this case, the distressing memories of listening to oneself sing out of tune.
Scientists find more insights into how a "zombie" fungus takes over ants' bodies. It bypasses their brains and infiltrates their muscles, causing them to lock their jaws in a death bite.
A deep-learning algorithm that solves the Rubik’s Cube and other combinatorial puzzles in increasingly different states in reverse from goal state, without domain-specific knowledge. DeepCubeA solves 100% of all test configurations, finding a shortest path to the goal state 60.3% of the time.
Gut Microbiota Changes in Patients with Bipolar Depression
Squeezing of blood vessels may contribute to cognitive decline in Alzheimer. Reduced blood flow to the brain associated with early Alzheimer's may be caused by the contraction of cells wrapped around blood vessels, according to a UCL-led study that opens up a new way to potentially treat the disease
Research suggests that older restaurant patrons tip more generously when exposed to uplifting and melancholic music compared to "baseline" background music when going out to eat. Background music wasn't found to have an effect on the tipping behavior of younger restaurant patrons.
Study finds subjects using OTC sunscreens quickly developed systemic levels of active ingredients that exceeded the 0.5 ng/mL concentration the FDA guidance says should trigger systemic safety testing. Results do not indicate that individuals should refrain from the use of sunscreen.
Those who are wealthier are more likely to say they earned their success, past surveys show. A new study (n=996) suggests winners are more likely than losers to credit their success to skill rather than luck, even when the odds are blatantly rigged in their favour, and little skill is involved.
Gender Stereotypes Have Changed: A Cross-Temporal Meta-Analysis of U.S. Public Opinion Polls From 1946 to 2018. Belief in competence equality increased over time, along with belief in female superiority among those who indicated a sex difference in competence.
