V404 Cygni: Huge rings around a black hole
This image features a spectacular set of rings around a black hole, captured using NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings reveal information about dust located in our galaxy, using a similar principle to the X-rays performed in doctor's offices and airports.
'Critical situation' as fires rage in Greece
"It's a very sad moment," said a villager in Evia who had to evacuate as a violent fire ravages the Greek island, one of dozens of blazes that have torn through the country this week in the worst heatwave in over three decades.
Family values outweigh politics in US Latinos' climate beliefs
For many in the U.S., human-caused climate change is a political tug-of-war between the left and the right. But for Latinos in this country, the issue hits much closer to home.
Decades of research bring quantum dots to brink of widespread use
A new article in Science magazine gives an overview of almost three decades of research into colloidal quantum dots, assesses the technological progress for these nanometer-sized specs of semiconductor matter, and weighs the remaining challenges on the path to widespread commercialization for this promising technology with applications in everything from TVs to highly efficient sunlight...
Control of the US Senate: What does history tell us about how much it affects legislative policymaking?
With the U.S. Senate evenly split between the Republican and Democratic caucuses—something that's only happened three other times—two political science scholars at the USC Dornsife College of Letters, Arts and Sciences were inspired to study one of those periods. Their research regarding the Senate during the 1953–54 session of Congress, published in the American Political Science Review,...
Doctoral candidate helps guide research to support future coral conservation
Serena Hackerott is giving coral researchers a much-needed beacon of hope for the future of coral restoration and conservation.
Research illuminates language of fireflies
A small flickering at dusk near the trees, a pinprick of light rising from the ground—fireflies bring an air of magic and wonder to long summer evenings. The twinkling conversation between beetles is commonly associated with mating patterns; and new data explains how swarms are able to achieve this communication.
Survey suggests climate change has reduced the presence of invasive Argentine ants
In 1993, Stanford University biology professor Deborah Gordon and her first graduate student, Katy Human, began a survey of ants at Stanford's Jasper Ridge Biological Preserve. Nearly 30 years, four more graduate students and scores of volunteers later, that survey continues on—and has recently yielded a surprising result.
Massive ancient lake across prairies emptied quickly enough to set off an ice age, study suggests
A flood of epic proportions drained at a rate of more than 800 Olympic swimming pools per second from a glacial lake that spanned the Prairie provinces more than 12,000 years ago, according to a University of Alberta-led study.

Ovarian cancer: Potential therapeutic target identified
- ScienceDaily
- 21/8/5 21:47
A gene called DOT1L appears to play a role in progression and severity of ovarian cancer, and inhibitors of the DOT1L enzyme may offer a new therapeutic approach for the disease, researchers say in a new study. The need is clear -- despite decades of work to develop new treatment modalities, the five-year survival of patients with advanced ovarian cancer is between 10 and 30 percent.
All in your head: Exploring human-body communications with binaural hearing aids
- ScienceDaily
- 21/8/5 21:06
Wearable technology seems all poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists have delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as...
Now how did that get up there? New study sheds light on development and evolution of dolphin, whale blowholes
Modern cetaceans—which include dolphins, whales and porpoises—are well adapted for aquatic life. They have blubber to insulate and fins to propel and steer. Today's cetaceans also sport a unique type of nasal passage: It rises at an angle relative to the roof of the mouth—or palate—and exits at the top of the head as a blowhole.
Venom has contributed to the species diversity of insects and fishes, new study reveals
The extraordinary diversity of insects and fishes, the most species-rich invertebrate and vertebrate groups in the animal kingdom, is partly due to the origin of venom, a new study of their evolution has revealed.

New findings about cancer cell growth may hold promise for future cancer treatments
- ScienceDaily
- 21/8/5 20:11
For a cell to grow and divide, it needs to produce new proteins. This also applies to cancer cells. Researchers have now investigated the protein eIF4A3 and its role in the growth of cancer cells. The study shows that by blocking or reducing the production of this protein, other processes arise that cause the growth and cell division of cancer cells to cease and eventually die.
