Researchers identify cell type that could be key to preventing marrow transplant complication
- ScienceDaily
- 23/3/24 23:44
While the donor cells in a bone marrow transplant can help cure the patient's blood cancer, they can also cause graft-versus-host disease -- in which donor T cells, a specialized immune cell in the blood, attack the patient's healthy cells. Before this study, there was no finite T cell population identified as the cause of GVHD. Now, researchers have identified the specific type of T cells that...
'Smart' bandages monitor wounds and provide targeted treatment

Researchers have developed a flexible electronic bandage for use on chronic wounds, particularly in diabetic patients. The bandage monitors signs of inflammation, collecting medical data and providing medication as needed.
Researchers find clue to help plants grow with low phosphorus levels
- ScienceDaily
- 23/3/24 23:44
Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
New type of entanglement lets scientists 'see' inside nuclei
- ScienceDaily
- 23/3/24 23:44
Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement...
Russians, American delayed in space to return in September
Two cosmonauts and an astronaut who were supposed to leave the International Space Station this month will be brought back to Earth in late September, doubling their time aboard the orbiting laboratory to more than a year, Russia's space agency announced Friday.
Blue Origin hopes to resume space flights 'soon' after 2022 accident
Jeff Bezos' space company Blue Origin said Friday it hopes to resume rocket flights "soon" following the conclusion of an investigation into a crash last year—but it must wait for US regulators to accept the findings.
Helping plants grow as phosphorus levels in soil deplete
Phosphorus is a natural mineral that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery by researchers at Michigan State University and the Carnegie Institution for Science is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Acquisitions can nix existing partnerships
Business alliances are valuable because they help companies supplement critical skills, enter new markets, and gain competitive advantages.
No aliens needed: 'Oumuamua's behaviour has a natural explanation, scientists say
A new theory suggests that radiation from interstellar space reconfigured ice on 'Oumuamua's surface to trap hydrogen gas that was released as a propellant as it approached the...
3 astronauts delayed on space station to return in September
Three astronauts who were supposed to leave the International Space Station this month will be brought back to Earth in late September, doubling their time aboard the orbiting laboratory to more than a year, Russia's space agency announced Friday.
Bezos' rocket company pins crash on overheated engine nozzle
An overheated rocket engine nozzle caused last year's Blue Origin launch failure that has grounded flights for six months, the company said Friday.
With fewer salmon to eat, Southern Resident killer whales spend less time in the San Juan Islands
As a key food supply declines, the endangered population of Southern Resident killer whales, known to frequent the Salish Sea off the coasts of Washington and British Columbia, is spending far less time in that region, a new study shows.
Flyover of Mars crater shows details of an ancient lake
Bob McDonald's blog: A new simulation video produced by NASA and the ESA shows off the planetary features that make scientists believe the Red Planet's Jezero Crater was a lake billions of years...
Sage warned Independent Sage its name would cause confusion, says Vallance
Chief scientist told former incumbent Sir David King the similarity would lead to mixed messagingThe government’s chief scientist warned a former incumbent not to confuse the public during the Covid pandemic by naming an independent expert panel after the group convened to advise ministers on the crisis.Sir Patrick Vallance revealed the clash in an interview at the Institute for Government on...
Mutation behind night blindness in humans helps whale sharks see in the dark
Even a fisher’s yarn would sell a whale shark short. These fish—the biggest on the planet—stretch up to 18 meters long and weigh as much as two elephants. The superlatives don’t end there: Whale sharks also have one of the longest vertical ranges of any sea creature, filter feeding from the surface of the ocean to nearly 2000 meters down into the inky abyss.

New index helps identify 55 unprotected marine protected areas
A new Paper Park Index (PPI) developed by researchers at the University of British Columbia's Sea Around Us initiative helped identify 55 marine protected areas (MPAs) across the world where enough fishing takes place to contravene the protection status officially assigned to such sites.
New experiment translates quantum information between technologies in an important step for the quantum internet
Researchers have discovered a way to "translate" quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking.
California ends some water limits after storms ease drought
California Gov. Gavin Newsom ended some of the state's water restrictions on Friday because a winter of relentless rain and snow has replenished the state's reservoirs and eased fears of a shortage after three years of severe drought.
Sexual harassment and customer abuse rife in retail, says Australian report
One in five retail workers has been sexually harassed at work in the past five years, most commonly by a senior colleague or a customer, according to a new report from the University of Sydney and the Australia National University.

NASA's Center for Near Earth Object Studies detected an asteroid that will pass Earth by 108,758 miles this weekend, which is closer than the moon's distance from Earth 238,855 miles away.
11 ways to improve airlines for customers
The name of the game is customer satisfaction, especially in the airline industry where companies are constantly jockeying for business by promising better service than their competitors. Now a professor at the University of Missouri has used artificial intelligence to sort through thousands of customer reviews and identify where airlines are falling short.
