“The domestic transportation sector presents an enormous opportunity to drastically reduce emissions that accelerate climate change and reduce harmful pollution.”

In what can be hailed a significant and impactful move, the U.S. Department of Energy, Transportation, Housing and Urban Development and the Environmental Protection Agency released a Blueprint on how to decarbonize the entire U.S. transport system. The strategy is hoped to cut all greenhouse emissions from the transportation sector by 2050.

The Biden administration unveiled a comprehensive blueprint for decarbonizing the transportation sector, which accounts for the nation’s largest source of greenhouse gas emissions.

Have you ever been cut off while driving and found yourself swearing and laying on the horn? Or come home from a long day at work and lashed out at whoever left the dishes unwashed? From petty anger to the devastating violence we see in the news, acts of aggression can be difficult to comprehend. Research has yielded puzzling paradoxes about how rage works in the brain. But a new study from Caltech, pioneering a machine-learning research technique in the hypothalamus, reveals unexpected answers on the nature of aggression.

The hypothalamus is a region linked to many innate survival behaviors like mating, hunting, and the fight-or-flight response. Scientists have long believed that neurons in the hypothalamus are functionally specific—that is, certain groups of neurons correlate to certain specific behaviors. This seems to be the case in mating behavior, where neuron groups in the medial preoptic area (MPOA) of the hypothalamus, when stimulated, cause a to mount a female mouse. These same neurons are active when mounting behavior occurs naturally. The logical conclusion is that these neurons control mounting in mice.

But when looking at the analogous neurons that control in another part of the hypothalamus, the VMHvl, researchers found a different story. These neurons could be stimulated to cause a male mouse to attack another male mouse, yet they did not show specific activity when the same neurons were observed in naturally fighting mice. This paradox indicated that something distinct was happening when it came to aggression.

On January 2023, 60 minutes interviewed Paul Ehrlich, the author of the 1968 Population Bomb.

Although I agree with some of the points, like the destruction of habitat, and climate change, and those points indeed need addressing. the overpopulation arguments in the book and the interview have already been proven wrong, repeatedly.

The 18th century Malthusian catastrophe predictions never materialized. Thanks to modern technology, new clean energy sources, and modern agriculture, our planet doesn’t have an overpopulation problem despite having more people today than at ant time in history.

It’s okay to have more kids. Kids will not “destroy the planet”. They may actually help.

Despite the 10-second lag, two astronauts had a lot to say about tech for space at CES 2023.

Today (Jan. 06), the International Space Station (ISS), which is the only location where people can investigate the long-term effects of living without gravity, completed the first call ever made in 4K to the Consumer Electronics Show (CES) 2023.

In the first instance, the discussion was unsurprisingly focused on what it’s like to be living in space now. After all, it’s not every day you get to watch two astronauts in real-time casually floating a mic between each other to answer our pressing earthly questions.

You may have come home with it after a recent trip to New England. Or you may have gotten it from that friend or family member who flew in from New York over the holidays.

The newest Omicron subvariant of concern is XBB.1.5, and it has arrived in Southern California. This version of the coronavirus is more contagious and more resistant to existing immunity than any of its predecessors.

“It’s just the latest and greatest and most infectious variant,” said Paula Cannon, a virologist at USC. “It’s amazing to me that this virus keeps finding one more trick to make itself even more infectious, even more transmissible.”

The world’s oldest lake can be found in southeastern Siberia where it’s believed to have existed for around 25 million years. As well as being the great great grandad of lakes, Baikal is also the deepest at 1,700 meters (5,600 feet). The impressive accolade means it’s home to around 20 percent of the world’s unfrozen freshwater reserves, and in a pond that massive you can expect a fish or two.

Lake Baikal is known as the “Galapagos of Russia” for the many weird and diverse species that call it home. Despite being covered by a thick layer of ice for five months each year, the ecosystem that has developed in the lake is astonishing and like few others. It is estimated that 80 percent of plants and animals that live in it are found nowhere else on the planet.

Among them is the Baikal oilfish, also known as the golomyankas. They’re scale-less fish with translucent bodies that can stretch to around 21 centimeters (8.3 inches). There are two species in the Comephorus genus, C. baikalensis and C. dybowski.

The spaceplane that will carry passengers to the “space business park” features its own inflatable space habitat.

Amazon founder Jeff Bezos’ space company, Blue Origin, has been hard at work alongside Colorado-based startup Sierra Space on the Orbital Reef project.

The two companies behind the project recently blasted a module prototype for the station to pieces as part of an ongoing test campaign.

One afternoon in the fall of 2019, in a grand old office building near the Arc de Triomphe, I was buzzed through an unmarked door into a showroom for the future of surveillance. The space on the other side was dark and sleek, with a look somewhere between an Apple Store and a doomsday bunker. Along one wall, a grid of electronic devices glinted in the moody downlighting—automated license plate readers, Wi-Fi-enabled locks, boxy data processing units. I was here to meet Giovanni Gaccione, who runs the public safety division of a security technology company called Genetec. Headquartered in Montreal, the firm operates four of these “Experience Centers” around the world, where it peddles intelligence products to government officials. Genetec’s main sell here was software, and Gaccione had agreed to show me how it worked.

He led me first to a large monitor running a demo version of Citigraf, his division’s flagship product. The screen displayed a map of the East Side of Chicago. Around the edges were thumbnail-size video streams from neighborhood CCTV cameras. In one feed, a woman appeared to be unloading luggage from a car to the sidewalk. An alert popped up above her head: “ILLEGAL PARKING.” The map itself was scattered with color-coded icons—a house on fire, a gun, a pair of wrestling stick figures—each of which, Gaccione explained, corresponded to an unfolding emergency. He selected the stick figures, which denoted an assault, and a readout appeared onscreen with a few scant details drawn from the 911 dispatch center. At the bottom was a button marked “INVESTIGATE,” just begging to be clicked.

Nature, red in tooth and claw, is rife with organisms that eat their neighbors to get ahead. But in the systems studied by the theoretical ecologist Holly Moeller, an assistant professor of ecology, evolution and marine biology at the University of California, Santa Barbara, the consumed become part of the consumer in surprising ways.

Moeller primarily studies protists, a broad category of unicellular microorganisms like amoebas and paramecia that don’t fit within the familiar macroscopic categories of animals, plants and fungi. What most fascinates her is the ability of some protists to co-opt parts of the cells they prey upon. Armed with these still-functioning pieces of their prey, the protists can expand into new habitats and survive where they couldn’t before.
