A new study found that a dollar increase in minimum wage correlated to nearly a six percent reduction in suicide rates among adults aged 18 to 64 with a high school degree or less education. Increasing the minimum wage was found to be most effective in the reduction of suicides when unemployment levels were the highest. According to the researchers' predictions, raising the minimum wage by just o
Japanese team spent 12 years on the project after digging up deep-sea mud For the first 2 billion years, life on Earth comprised two microbial kingdoms – bacteria and archaea. They featured an innumerable and diverse variety of species, but, ultimately, life on Earth was not that exciting judged by today's standards. Then, the theory goes, a rogue archaeon gobbled up a bacterium to create an enti
It's Alive! Scientists at the University of Colorado, Boulder have created what The New York Times calls a "living concrete," teeming with photosynthetic bacteria, that can grow itself and regenerate itself — much like a living organism. The concrete is a mixture of gelatin, sand, and cyanobacteria that cools similarly to Jell-O, the Times reports. The resulting structure was able to regenerate i
The call is a nightmare, registering up to 90 decibels from 3 feet away. (Meredith Miotke/) In its native Puerto Rico, the coquí frog's eponymous croak is the stuff of lullabies. According to myths of the island's indigenous Taíno people, the tiny amphibians memorialize a goddess's lost lover by singing his name over and over: ko-kee, ko-kee .

In 1947, 13% of all personal consumption expenditures in the US was for Clothing. Today, it's a mere 3%. Food went from 25% to just 8%. Technology has made our most basic needs into minor expenses, well almost all of them. Housing has gone up from 9% in 1947 to 16% today. 1947 was a low year, but still, for 90 years our spending on housing has been stubbornly at roughly 15% of personal expenditur
One of the hallmark behaviors of social groups is division of labor, where different group members become specialized to carry out complementary tasks. By dividing labor, cooperative groups increase efficiency, thereby raising group fitness even if these behaviors reduce individual fitness. We find that antibiotic production in colonies of Streptomyces coelicolor is coordinated by a division of l
Various slow earthquakes (SEQs), including tremors, very low frequency events, and slow slip events (SSEs), occur along megathrust zones. In a shallow plate boundary region, although many SEQs have been observed along pan-Pacific subduction zones, SSEs with a duration on the order of a year or with a large slip have not yet been detected due to difficulty in offshore observation. We try to statis
Microglia and infiltrating macrophages are thought to orchestrate the central nervous system (CNS) response to injury; however, the similarities between these cells make it challenging to distinguish their relative contributions. We genetically labeled microglia and CNS-associated macrophages to distinguish them from infiltrating macrophages. Using single-cell RNA sequencing, we describe multiple
Aryl hydrocarbon receptor (AHR) is an essential regulator of gut immunity and a promising therapeutic target for inflammatory bowel disease (IBD).

The landslide did n
The malignancy potential is correlated with the mechanical deformability of the cancer cells. However, mechanical tests for clinical applications are limited. We present here a Triangular Correlation (TrC) between cell deformability, phagocytic capacity, and cancer aggressiveness, suggesting that phagocytic measurements can be a mechanical surrogate marker of malignancy. The TrC was proved in hum
Development of effective tumor cell–targeted nanodrug formulations has been quite challenging, as many nanocarriers and targeting moieties exhibit nonspecific binding to cellular, extracellular, and intravascular components. We have developed a therapeutic nanoparticle formulation approach that balances cell surface receptor-specific binding affinity while maintaining minimal interactions with bl
While immunotherapy holds great promise for combating cancer, the limited efficacy due to an immunosuppressive tumor microenvironment and systemic toxicity hinder the broader application of cancer immunotherapy. Here, we report a combinatorial immunotherapy approach that uses a highly efficient and tumor-selective gene carrier to improve anticancer efficacy and circumvent the systemic toxicity. I
This paper reports on an analytical study of the intrinsic shapes of 523 whiskers from 15 rats.

Among the many things we've become addicted to on our smartphones is checking the weather. If you're anything like me, you open a weather app at least twice a day: in the morning to know what to expect for the day ahead, maybe before your commute home so you can prepare for possible rain or snow, and sometimes before bed to get an idea of what to wear or what activities to plan for the next day.
Stardust from a meteorite is five to seven billion years old—the oldest solid material ever found on Earth—report researchers who determined its age. Stars are born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die. When they die, they pitch the particles that formed in their w

In recent months, Democratic presidential candidate Senator Elizabeth Warren has come under fire because of the high cost of her proposed Medicare-for-All health plan. It's estimated to cost the country $20.5 trillion , twice the estimated amount of her other policy proposals. As The Atlantic 's Ron Brownstein wrote in November , that's more than the federal government now spends on Social Securi
Last week's hostilities with Iran prompted the most significant foreign-policy debate on the right since Donald Trump became president––a debate that is ultimately about America's role in the Middle East and the world. At a moment when President Trump's actions are difficult to predict––and when many voters are wondering whether Republicans or Democrats are more likely to end old wars and avoid n
Aarhus-forskere har i et nyt studie påvist en sammenhæng mellem antallet af multisyge patienter og udbrændthed blandt praktiserende læger. Det bør give anledning til nye tanker om organiseringen af almen praksis, lyder det fra studiets førsteforfatter.
Linguists are famous—or perhaps infamous—for our tolerant attitude toward language and how it changes. Given the widespread misconception that we are professional grammar police, we often disappoint people in saying that it is not scientifically "wrong" to say "less books" rather than "fewer books" or to say "irregardless" rather than "regardless." Among the many reasons we view language so impar
Lægemiddelstyrelsen har siden november måned givet mere end 430 praksislæger en generel udleveringstilladelse til fnatmedicin. Det har betydet hurtigere behandling hos egen læge, men papirarbejdet er fortsat unødigt tungt, ifølge DSAM-formand.
Researchers say they have successfully created another embryo of the nearly extinct northern white rhino in a global effort to keep the species alive. Just two animals remain, and both are female.

Phosphorus is an essential element for life as we know it. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency's probe Rosetta. Their research shows where molecules containing phosphorus form, how this element is carried in comets, a

By embracing a rational approach to life, society at large has stripped away meaning from psychologically important elements of life, including death. A lack of meaning leads to discomfort, which results in a desperate search for narrative in things that feel transcendent and bigger than ourselves. For some, the wonder of magic fills that void and provides the meaning and structure that has been
Phosphorus, present in our DNA and cell membranes, is an essential element for life as we know it. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency's probe Rosetta. Their research shows, for the first time, where molecules contain

Many liver cancer tumors contain a highly diverse set of cells, a phenomenon known as intra-tumor heterogeneity that can significantly affect the rate at which the cancer grows, Mount Sinai researchers report. The immune system's contribution to this heterogeneity can have major clinical implications.

Nature Communications, Published online: 15 January 2020; doi:10.1038/s41467-019-14140-y The Janzen-Connell hypothesis posits that seedlings may be less likely to establish near conspecifics due to shared natural enemies. Here, Jia et al. show that tree species traits determine whether fungal pathogens or insect herbivores inhibit seedling recruitment and survival in a temperate forest.

När vi pratar om global uppvärmning menar vi oftast att temperaturen ökar på land och i atmosfären. Men mer än 90 procent av uppvärmningen sedan 1970 har ägt rum i havet, och därför är havstemperaturen den säkraste mätaren av klimatkrisen globalt. Det säger kinesiska och amerikanska forskare bakom en stor forskningsstudie med data från hela världen. De senaste tio åren har varit de varmaste som up
Last weekend, Donald Trump offered Iran some sage, if obvious, advice: Do not kill your protesters. The warning came amid ongoing demonstrations in Iran following the country's admission that it had mistakenly struck down a Ukrainian airliner, killing all 176 people on board, including 83 Iranian nationals. The announcement followed days of denial and obfuscation by Iranian authorities. Anger abo

Telling youth not to 'sext' doesn't seem to be reducing the prevalence of them sharing nude photos or videos. A national sample of about 5,000 youth ages 12 to 17 showed 14 percent had sent and 23 percent had received sexually explicit images. Researchers say it's time to teach teens 'safe' sexting and provide important tips to avoid significant and long-term consequences, such as humiliation, ext

American cancer survivors, particularly those 64 years or younger, faced substantial medical financial hardship and sacrifices in spending, savings, or living situation, according to data from a survey.
A new study cautions that while Google is adept at sorting the most reliable websites to the top of the list, most websites providing information on probiotics are from unreliable commercial sources. The public should be wary of searching for probiotic information online as the majority of webpages originate from unreliable sources and health-benefit claims are often not supported by robust scient
Throughout her campaign, Senator Elizabeth Warren has largely sidestepped the question of sexism. It's a lose-lose situation: Women candidates don't want to seem whiny, but they also don't want to look weak if they're insulted or discriminated against because of their gender. When CNN reported on Monday that Bernie Sanders told her in 2018 that a woman could not be elected president, Warren seeme
In 2008, Barack Obama won the Democratic presidential nomination arguably based on a single policy position that distinguished him from his chief rival: his opposition to the U.S.-led war in Iraq from its outset. Twelve years later, Senator Bernie Sanders of Vermont could conceivably capture the party's nomination because of that same stance on that same war. At tonight's Democratic debate, in Io
For Prebble et al. (1), the cultivation of introduced semiaquatic tropical taro (Colocasia esculenta) on cooler southern Pacific islands during the Polynesian "initial colonization period" (ICP) (1200 to 1500 CE) represents a "striking" Neolithic example of nonoptimal, marginal crop production. In that respect, ICP taro pollen from Ahuahu, a warm-temperate,…
It is easy to obtain antibiotics without prescription in retail pharmacies in China, even though selling antibiotics without a prescription conflicts with regulations, a study published in the open-access journal Antimicrobial Resistance & Infection Control suggests.
