Scientists have uncovered the mechanism behind why eating late at night is linked to weight gain and diabetes. The connection between eating time, sleep and obesity is well-known but poorly understood, with research showing that over-nutrition can disrupt circadian rhythms and change fat tissue.
Tentacle robot can gently grasp fragile objects
- ScienceDaily
- 22/10/21 22:35
Taking inspiration from nature, researchers designed a new type of soft, robotic gripper that uses a collection of thin tentacles to entangle and ensnare objects, similar to how jellyfish collect stunned prey. Alone, individual tentacles, or filaments, are weak. But together, the collection of filaments can grasp and securely hold heavy and oddly shaped objects. The gripper relies on simple...
Hubble views a turbulent stellar nursery
The lives of newborn stars are tempestuous, as this image of the Herbig-Haro objects HH 1 and HH 2 from the NASA/ESA Hubble Space Telescope depicts. Both objects are in the constellation Orion and lie around 1,250 light-years from Earth. HH 1 is the luminous cloud above the bright star in the upper right of this image, and HH 2 is the cloud in the bottom left. While both Herbig-Haro objects are...

Luis Jaime Castillo Butters, a prominent Peruvian archaeologist who was among the first members of the U.S. National Academy of Sciences to be removed after a 2019 bylaws update allowed expulsion for documented misconduct violations, filed a $5 million defamation lawsuit against the academy and NAS President Marcia McNutt this month. The suit alleges that “NAS and McNutt made false...
Butterfly wing patterns emerge from ancient 'junk' DNA

New dates suggest Oceania's megafauna lived until 25,000 years ago, implying coexistence with people for 40,000 years
For most of Australia's human past sea levels were lower than they are today. Australia's mainland was connected to Papua New Guinea and Tasmania as part of a larger landmass called "Sahul".
Reducing noise pollution with acoustic walls and rubberised roads
Sound-diffracting walls and rubberised asphalt ingredients tackle the major environmental concern of noise pollution from traffic.
Fully mature hair follicles grown in cultures
A team of researchers from Japan studying the processes of hair follicle growth and hair pigmentation has successfully generated hair follicles in cultures. Their in vitro hair follicle model adds to the understanding of hair follicle development which could contribute to development of useful applications in treating hair loss disorders, animal testing, and drug screenings.
Avoiding extinction: Some Asian animals found thriving near humans
Some of Asia's largest animals, including tigers and elephants, are defying 12,000 years of extinction trends by thriving alongside humans, a University of Queensland-led study has revealed.
Chang'E-5 samples reveal how young volcanism occurred on the moon
A new study led by Prof. Chen Yi from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) provides an answer to the question of how young volcanism occurred on the moon.
The science of how plants register trauma includes a precursor to the calcium wave
Longstanding theories of how plants rely on calcium waves to respond systemically to wounding and other stresses have been given fresh perspective.
Disadvantaged children missing out on meals in childcare
Researchers at The University of Queensland have found children in disadvantaged communities often go hungry when they attend early education and childcare centers.
War in Ukraine widens global divide in public attitudes toward US, China and Russia: Report
Around the world, public attitudes toward international politics are coalescing into two opposing blocks: liberal democracies favoring the United States (US) and citizens of more authoritarian nations who back China and Russia—a process accelerated by the war in Ukraine.
