Manure produces a whole lot of biogas, which these farmers burn to create heat and electricity.
A new process that turns cow waste into usable gas can be used to reduce methane and power vehicles.
The claim of a gravitational wave background suggests the universe is constantly roiled by violent events that happened over the past 13 billion years.
The Planck era

In less time than it takes to snap your fingers, the universe flashed into existence.
Cosmogenesis is the breathtaking story of how this happened. It includes, in its later moments, the creation of the primordial elements and depicts their organization by dark matter and gravity into vast cosmic structures on the largest scales. Meanwhile, on smaller scales, local gravitational collapse created stars and, later, planets.
The prelude to this story began with a major cosmological event: inflation. Between 10-36 and 10-34 seconds after the Big Bang, the physical scale of our universe doubled in size more than 50 times, so that by today, it is trillions of times larger than the 14 billion-light-year extent we can observe.
A new type of macrophage recently identified in atherosclerotic lesions could provide a missing link in understanding the inflammatory origins of the common yet fatal condition.
Atherosclerosis is a common condition in which an accumulation of fat, named plaque, builds up on the innermost walls of arteries, causing them to become narrow and restrict the blood flow to vital organs such as the heart and the brain. It can be life-threatening if untreated—narrow arteries increase the risk of a blockage and lead to a heart attack or stroke.
Macrophages are immune cells that play essential roles in organ homeostasis as well as infection and injury. Key to their success is the ability to alter their transcriptional patterns of gene expression to perform highly-specialized roles in specific organs and tissues. However, their prominent role means that when things go wrong, macrophages can be impactful drivers of disease.
In the past three years, the workplace has changed dramatically.
According to a recent McKinsey survey, 98 million American workers now have the option to perform their jobs remotely. And 77 percent of respondents to a recent Deloitte survey cited greater workplace flexibility as a top reason to switch jobs.
Yet the exact same proportion, 77%, told Deloitte they have felt burnout at their current job. Another study found that about half of the fulltime employees surveyed feel disconnected from their coworkers.
In a new study published in Aging Cell [1], researchers report that transient activation of the Yamanaka factor Oct4 allowed partial reprogramming of cells, which led to rejuvenation in these cells and in a mouse model of premature aging.
The way AI models structure text may have something to do with it, according to the study authors.
Jodhpur couple Rajnush and Vedika Agarwal have turned their ancestral land into an experiential farm named MharoKhet, where they not only grow several organic exotic vegetables, but also deliver the freshest produce within hours of harvest.
Engineers from Rice University and the University of Maryland have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky water, skin, bone and other media that reflect scattered light and obscure objects from view.
“Imaging through scattering media is the ‘holy grail problem’ in optical imaging at this point,” said Rice’s Ashok Veeraraghavan, co-corresponding author of an open-access study published today in Science Advances. “Scattering is what makes light—which has lower wavelength, and therefore gives much better spatial resolution—unusable in many, many scenarios. If you can undo the effects of scattering, then imaging just goes so much further.”
Veeraraghavan’s lab collaborated with the research group of Maryland co-corresponding author Christopher Metzler to create a technology they named NeuWS, which is an acronym for “neural wavefront shaping,” the technology’s core technique.
