The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was 'normal' and 'below the historical average'.An international team of scientists writing in the journal Global Change Biology say the number of active fires in August was actually
Thanksgiving is just a regular dinner. With a ton more menu options. And your in-laws. And your sister whose political views radically oppose those of your grandfather. What could possibly go wrong? Even for the most confident cooks, Thanksgiving dinner is a massive undertaking. The sheer scale and scope of this holiday's menu are so over-the-top that it's tempting to drop serious cash on product

Scientists who scanned the skies above dozens of U.S. cities have made a surprising discovery about the smog that's suspended over Los Angeles: one of its key ingredients isn't disappearing as fast as it once did.
As they present their findings to the public, House Democrats may find it easier to let President Donald Trump build the case for impeachment himself. The testimony that Marie Yovanovitch, the former ambassador to Ukraine, delivered to Congress this morning was perhaps as politically damaging to Trump as anything presented during the first day of House impeachment hearings, on Wednesday. In a qui
Too often the concept of a circular economy is muddled up with some kind of advanced recycling process that would mean keeping our industrial system as it is and preserving a growing consumption model. This idea is based on a belief that recycling will take care of everything. One of the most startling examples of this is the part of the European Union's Circular Economy Action Plan which aims to
Galaxy Brain A preliminary study suggests that a zero-gravity environment causes structural changes to the human brain — and that extended stays in space could lead to cognitive decline. Brain scans of astronauts revealed structural changes, likely caused by the time spent in microgravity, and correlated them to signs of cognitive impairment, according to Space.com . It's just the latest in a lon

Dry reforming of methane (DRM) is the process of converting methane (CH4) and carbon dioxide (CO2) into synthesis gas (syngas). Since CO2 and CH4 are the two most important atmospheric greenhouse gases (GHGs), as well as abundant and low-cost carbon sources, DRM has the potential to mitigate rising GHG emissions and simultaneously realize clean(er) fossil fuel utilization.
Companies often target consumers based on gender, but this kind of advertising shortcut doesn't just perpetuate outdated stereotypes — it's also bad for business, says marketing expert Gaby Barrios.

The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become immune against these compounds in turn, which enhances their ability to fight the western corn rootworm, as researchers show. This mechanism may contribute to improving biol

Following a nearly 25-year search across three continents, parents of a pair of sisters — who as children slowly became paralyzed from the waist down — finally have a diagnosis. Thanks to a chance viewing on French TV of a story about another physically disabled child who regained her mobility after being diagnosed at TGen, the parents of the two sisters contacted TGen, hoping to end their decad
Lichens — a combo of fungus and algae — can grow on bare rocks, so scientists thought that lichens were some of the first organisms to make their way onto land from the water, changing the planet's atmosphere and paving the way for modern plants. But a closer look at the DNA of the algae and fungi that form lichens shows that lichens likely evolved millions of years after plants.
As an alternative to the depletion of fossil resources, the reduction of CO2 emitted from fossil fuel combustion into valuable chemicals and fuel has drawn increasing attention. Due to the highly thermodynamic stability of CO2, it is still very challenging to find a sustainable and cost-efficient route to selectively convert inert CO2 at a high conversion rate under mild conditions. The water coul

An international team of researchers has found evidence that magnetic reconnection is the source of spicule generation on the surface of the sun. In their paper published in the journal Science, the group describes their study of the sun and what they learned about it.
Body cells are workshops that continuously operate to produce and process substances to maintain metabolism. When a substance enters a cell for processing, it is surrounded by a portion of the cell's outer membrane to form a sac. The sac then buds off into the cell and becomes a vesicle containing the substance. This ingestion of substances by the cell is called endocytosis. The vesicle is then qu
"Rats are a particularly damaging invasive species in New Zealand," Henry says. "Understanding them better, including how they move through an urban environment and what their habitat preferences are, will give insight into how to more effectively eradicate them and protect native flora and fauna, especially as there's currently very little known about the ecology of urban ship rats."

The Copernicus Sentinel-2 mission takes us over the Lake Tai, the third largest freshwater lake in China. The lake, also known as Lake Taihu, is located in the Jiangsu province and is approximately 70 km long and 60 km wide, with an average water depth of approximately two meters. The lake discharges its waters through Wusong, Liu, Huangpu and several other rivers.
For the LHCb detector at the Large Hadron Collider, the ongoing second long shutdown (LS2) of CERN's accelerator complex will be a period of metamorphosis. After two successful data-collection runs, the detector is being upgraded to improve the precision of its physics measurements, many of which are the best in the world. There will therefore be five times more collisions every time proton bunche

Here's a surprise: a report of a completely new (and rather unusual) allotrope of carbon. There doesn't appear to be a manuscript out there yet, but the results were presented earlier this month at a conference in Richmond and earlier this year at the APS meeting, and caused a stir. Weirdly, this one appears to have properties that are best described as semi-metallic: it's harder than stainless s

When prolonged periods of severe weather strike, two things often get the blame these days: climate change and the jet stream. Many have expressed concerns that the rapidly melting Arctic is now disturbing the jet stream, bringing more frequent bouts of wild weather. But potentially even more powerful changes are afoot in the tropics—and the consequences could be severe.
A team of scientists have used satellite data to augment measurements of North Korean nuclear tests on the ground. The researchers find that the most recent test shifted the ground by a few meters, and estimate it to be equivalent to 17 times the size of the bomb dropped on Hiroshima in 1945.
New research reveals how a protein that specializes in killing off invading viruses latches on to attackers, as well as how some viruses like HIV evade capture and death. Humans have evolved dynamic defense mechanisms against the viruses that seek to infect our bodies—proteins that specialize in identifying, capturing, and destroying the genetic material that viruses try to sneak into our cells.

For some women, sex becomes less satisfying with age, with a pronounced decline during perimenopause. A new study indicates that sexual dysfunction increases by nearly 30% during perimenopause, and vaginal dryness most often has the greatest effect on desire, arousal, lubrication, and overall satisfaction. Study results were published this week in Menopause, the journal of The North American Menop
Lichens — a combo of fungus and algae — can grow on bare rocks, so scientists thought that lichens were some of the first organisms to make their way onto land from the water, changing the planet's atmosphere and paving the way for modern plants. But a closer look at the DNA of the algae and fungi that form lichens shows that lichens likely evolved millions of years after plants.

Light can be directed in different directions, usually also back the same way. Physicists have however succeeded in creating a new one-way street for light. They cool photons down to a Bose-Einstein condensate, which causes the light to collect in optical 'valleys' from which it can no longer return. The findings could also be of interest for the quantum communication of the future.
