Depression may not be one biological condition, but several distinct patterns of brain activity hiding under the same diagnosis. Researchers studying 263 people with depression identified five brain profiles, each showing different patterns of communication between brain regions and associations with symptoms such as anxiety, trauma, and substance abuse.
AI is being integrated into our work at a growing rate. Andreas Bergqvist, a Ph.D. student at the Department of Information Technology, has teamed up with colleagues to investigate how AI, automation and robotization affect work engagement.
A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone expected. Using the James Webb Space Telescope, Brittany Miles, assistant astronomer at the University of Arizona's Steward Observatory, led a team that spent 11 hours staring at WISE 0855, the coldest known brown dwarf, collecting a spectrum of its light every 15 minutes.
Scientists have created a new family of materials whose behavior can be tuned by changing their metallic "recipe"βopening new possibilities for uses including gas storage and sensing.
Today, the discussions of sports analytics in the 2011 movie "Moneyball" often seem quaint. The idea of a team using data to find players who may be more valuable than meets the eye (and less expensive) no longer surprises anyone.
Scientists have demonstrated a remarkable new antenna that resembles a lightsaber, using a laser to create a tunable beam of plasma capable of transmitting radio waves. The technology could revolutionize wireless communications by allowing antennas to change their size and direction on demand, with promising applications in satellites, radar, and space exploration.
Finding a single cancer cell in a tube of blood is a bit like finding a needle in a haystack. As researchers seek to detect ever-smaller and rarer targets, from viruses to circulating tumor cells in blood, the demand for ultrasensitive, robust sensors that are practical for real-world samples continues to grow.
Localized pitting corrosion can cause sudden failure in aluminum components even when overall corrosion rates are low. Steam coating offers a water-vapor-based route to protective boehmite films, but processing simultaneously changes film thickness, surface morphology, crystallinity and substrate defects.
A strange chemical signature in old Hubble observations may point to a planet that formed after its star had already died. Astronomers found unusually high levels of niobium around the white dwarf HS 0209+0832, suggesting some of the starβs expelled material may have assembled into a new gas giant. TESS data also hints at a Jupiter-sized planet orbiting just 3.7 million miles from the star.
When a dying star runs out of fuel and sheds its outer layers, its remaining core can become an approximately Earth-sized, extremely dense stellar remnant called a white dwarf. For a white dwarf that is not strongly rotating or magnetized, there is a well-known upper mass limit of about 1.4 times the mass of the sun, known as the Chandrasekhar limit.
Feeling secure in a relationship is not only about how people connect with their partners today. It may also depend on how confident they are that the relationship will continue into the future. Feelings of closeness, trust and connection, together with a sense that the relationship is stable and has a future, can shape how people experience their romantic relationships.
The threat of cyberattacks against American agriculture and food systems is growing, and Washington State University researchers are helping to lead a call for a national consortium of land-grant universities to study and combat the threat.
For highly fragile quantum information systems, the ability to store quantum information is vitalβbut also challenging. Quantum information is transported in particles of light called photons, which often must be temporarily paused (or "stored") while other, slower quantum operations catch up. This storage must be performed on microchips as small as 1 centimeter (0.4 inches)βa distance covered by light in a few trillionths of a second. Storing photons for a microsecond would represent a massive leap forward for the capabilities of quantum chips.
Rocks in the asteroid belt rotating at ultra-fast speeds suggest our understanding of asteroid structure might be wrong
Episodic lava fountaining is a rare volcanic behavior in which repeated, hours-long bursts of molten lava and gas are spewed from volcanic vents, with quiet pauses lasting days to weeks between episodes. These lava fountains have been observed in active volcanoes in places like Hawaii, Iceland and Italy, but researchers still do not fully understand what starts, sustains or stops these individual fountain episodes.
Most covid-19 cases are caused by a particular type of variant, but do we need to worry every time a new one emerges?
Majestic African antelopes known as gemsbok have been roaming the U.S. Southwest since their introduction in the 1960s and 1970s. Brought to New Mexico as a game species for hunting, gemsbok quickly settled in, expanding more than 100 kilometers (62 miles) from their introduction point. University of Illinois Urbana-Champaign researchers say that's due to their exceptional adaptations to arid conditions, which they predict will dramatically expand under climate change.
U.S. colleges and universities have long struggled to increase the racial diversity of their faculty.
Imagine you're road-tripping across the country 10 years from now. You spend a few minutes charging your electric vehicle and then set off β and your car's solar paint keeps it charged as you drive. Your eyes are on the stunning scenery, taking in the vistas along Route 66 or the grandeur of the Rocky Mountains, or you're catching up on messages. Your hands barely touch the wheel, and your foot doesn't push a pedal. Your car communicates with others on the road, so there's no need to brake suddenly or swerve. That's because it knows a vehicle five cars up from you has done so, and all those in between are slowing at exactly the right pace to avoid dramatic changes in trajectory.And when you ...
Parts of Earth's climate system can change abruptly once warming pushes them beyond critical thresholds. The Greenland and Antarctic ice sheets, the Amazon rainforest, coral reefs and major ocean currents are all among the systems containing potential climate tipping points.
