Volume of debris in the unexplored twilight zone is an ‘emerging threat’ to reefs already stressed by climate crisis, say scientists

Nature has tried some pretty wild approaches to life's problems over the eons, and that's true for vision.

Better farming techniques across the world could lead to storage of 31 gigatonnes of carbon dioxide a year, data shows. That amount is not far off the 32 gigatonnes gap between current planned emissions reduction globally per year and the amount of carbon that must be cut by 2030 to stay within 1.5C.

Signs of life beyond Earth could take forms that are clearly artificial – radio or light signals, or even evidence of large-scale engineering.

I know this is pretty basic for many of you, but I'm happy to see this from NASA.

Scientists have discovered an anomalous blob of heat on the far side of the moon.

This mysterious hotspot has a strange origin: It's likely caused by the natural radiation emanating from a huge buried mass of granite, which is rarely found in large quantities outside of Earth, according to new research. On the moon, a dead volcano that hasn't erupted for 3.5 billion years is likely the source of this unusual hunk of granite.

From COVID-19 to climate change, scientists are facing a flood of hate mail, threats and harassment from conspiracy theorists.

UChicago researchers hope "islands" of exciton condensation could pave the way for new discoveries. Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Meanwhile, just outside their window, trees are absorbing sunlight and converting it

The NASA VIPER rover will explore the south pole of the moon as early as 2024. But first, it has to pass the ramp test.

Hotspots beneath cities deform the ground, causing important infrastructure to crack under stress

Stripped down to a skeletal genetic blueprint, the artificial cells were dealt a losing hand for survival—yet they thrived.

How bacteria use carbon dioxide and electricity to produce useful chemical In the field of microbial electrosynthesis, microbes utilize CO2 and electricity to generate substances like alcohol. The precise biological mechanisms underpinning this process have, until recently, been largely theoretical

A gene-editing technique makes mosquitoes produce antibodies against the malaria parasite, which could mean cases in people are also slashed

Observations of a wild colony of macaques over three years show same-sex sexual behavior among males is widespread and may be beneficial.

Since 2009, a cloistered band of hard-rock geologists and other scientists have toiled on a mission of great consequence. On Tuesday they will deliver the last of their findings—the location of ground-zero for the Anthropocene, the proposed geological epoch borne of humanity's outsized impact on the planet.

Beneath the seawater in Japan's Beppu Bay lie layers of seemingly unremarkable sediment and sludge that tell the story of how humans have fundamentally altered the world around them.

Scientists developed a novel, sun-activated catalyst that reduces reliance on rare metals and enhances the efficiency of esterification reactions, crucial for products like medicines and polymers. This breakthrough in chemical synthesis promises significant sustainability improvements.

Study of modern DNA shakes up ideas of when and where contact happened.

The Northern Lights, or aurora borealis, will be visible across areas like Seattle, Des Moines [Iowa], Chicago, Cleveland, Boston, and Halifax [Nova Scotia] on Wednesday. That night the KP-index, which measures global auroral activity ranges from 0 to 9, will be at Kp-5. Anything above a Kp-5 rating means a geomagnetic storm will occur. On Thursday, the aurora will intensify as the KP-index increases, making the colorful lights more visible, according to The Geophysical Institute at the University of Alaska at Fairbank.

A new ferroelectric polymer that efficiently converts electrical energy into mechanical strain has been developed by Penn State researchers. This material, showing potential for use in medical devices and robotics, overcomes traditional piezoelectric limitations.

"This is profiteering, not innovation."

So Kamath went to Florida, where she identified individual anoles and tracked their movements day in, day out. Kamath studied the anoles “in a larger area, in a longer period of time than anyone else had ever done,” says Losos, who is now at Washington University in St. Louis. But instead of revealing territorial differences, this massive dataset showed that the anoles weren’t actually territorial in the first place.

Kamath looked into the historical record to see where the idea of anole territoriality originated. It started with a 1933 paper that described frequent sexual behavior between male lizards in the lab. The authors had concluded that this lab behavior must be “prevented by something” in the wild, Kamath says, which they inferred was the males protecting territories. “The very first conclusion,” she says, “was based on a homophobic response to observing male-male copulation.” That shaky conclusion caught on, and later researchers assumed it to be true.

A two-front biological and cyber attack could lead to a U.S. defeat before we know what hit us.

Major depression has previously been associated with abnormalities in REM sleep. Excess REM sleep would diminish noradrenaline, resulting in decreased binding to the ɑ-2 receptor in the medial frontal lobes comprised of the ACC and the medial prefrontal cortex. The absence of REM sleep with TSD may give some participants a break to improve top-down control of the amygdala, resulting in an antidepressant effect.

I would like to inquire about two specific topics related to phage and bacterial genetics. I would greatly appreciate any recommendations or research papers you can provide for further studying these subjects.

Question 1: Phage Genetic Material Storage in Bacteria for "Immunity" I am particularly interested in understanding how phage genetic material is stored in bacterial DNA after phage destruction, specifically through the CRISPR/Cas system. I would like to incorporate and explore the mechanisms and processes involved in this fascinating phenomenon in my scholarly thesis.

Question 2: Bacterial Integration and Utilization of Phage Genes After Successful Elimination of Phage Infection Another area I would like to address in my thesis is whether bacteria can integrate and utilize phage genes after successfully eliminating phage infections, directly for regulation or protein synthesis.

I greatly appreciate any guidance or resources you can provide. Thank you very much for your time and assistance.

Multiple southern states and a few midwestern states are at "extreme threat" levels of "wet bulb temperature".
