- How studying fossilized parasites can contribute to knowledge of infectious diseaseson November 8, 2021 at 6:16 pm
Over the last decade, John Huntley, a paleontologist and an associate professor of geological sciences at the University of Missouri, has studied the history of parasite-host interactions. These interactions can occur either outside a host's body, such as a tick, or inside a host's body, such as a flatworm.
- Drones, viral videos help 'Nature' thrive after 40 yearson November 8, 2021 at 5:19 pm
Forty years ago, the programmers at PBS were eager to experiment, so they took a chance and started a new series on animal behavior in the wild called "Nature."
- Study finds that ancient penis worms invented the 'hermit crab' lifestyleon November 8, 2021 at 4:00 pm
A new study by researchers from Durham University and Yunnan University reveals that penis worms (Priapulida) invented the 'hermit' lifestyle, some 500 million years ago, at the rise of the earliest animal ecosystems in the Cambrian period.
- What can scientists learn from worms that glow in the dark? The secrets of regeneration for starterson November 8, 2021 at 4:00 pm
Cut off the head of a three-banded panther worm and another will take its place—mouth, brain, and all. Cut off its tail and it will grow another. Cut the worm in three separate pieces and within eight weeks there'll be three fully formed worms. Cut it in … well, you get picture…
- Researchers develop CRISPR-based rapid diagnostic tool for SARS-CoV-2on November 8, 2021 at 3:47 pm
,Blending experts from molecular genetics, chemistry and health sciences, researchers at the University of California San Diego have created a rapid diagnostic technology that detects SARS-CoV-2, the coronavirus that causes COVID-19.
- Rapid-fire climate extremes leave the Great Barrier Reef a bleached 'checkerboard'on November 8, 2021 at 3:47 pm
A new study reveals the impacts of multiple climate extremes on coral reefs over the past three decades, with only 2% of the Great Barrier Reef escaping bleaching in that time.
- Guazia, the earliest winged seed without cupuleon November 8, 2021 at 3:46 pm
In a paper published in National Science Review, a Chinese group of palaeobotanists described a new genus and species of Late Devonian ovule (seed before fertilization), Guazia dongzhiensis gen. et sp. nov., which is borne terminally and has folded, wing-like integumentary lobes but no cupule. G. dongzhiensis presents evidence for Devonian acupulate ovules (ovules without a cupule) and specialized integuments adapted to wind dispersal.
- How random is stem cell development?on November 8, 2021 at 3:41 pm
In just a few weeks a completely new organism develops from a fertilized egg cell. The real miracle is that a bunch of identical stem cells turns into completely different, specialized cell types. A team led by Christian Schröter, group leader at the Max Planck Institute of Molecular Physiology in Dortmund, has now been able to show that the specialization of individual cells during embryonic development is not, as previously assumed, exclusively left to chance but is rather determined by cell communication.
- Gene-editing discovery yields high promise for wheat fertility in a changing climateon November 8, 2021 at 3:39 pm
A gene which has profound effects on the production of seeds has been identified by researchers from the John Innes Centre. Gene-editing techniques helped to identify and explain the key gene, ZIP4, in wheat which is responsible for maintaining 50% of yield in this global crop.
- Ancestral sequence reconstruction of avian influenza virus transmission in pigson November 8, 2021 at 2:22 pm
Researchers at the School of Public Health, LKS Faculty of Medicine of The University of Hong Kong (HKUMed), in collaboration with Duke-NUS Medical School (Duke-NUS) and St. Jude Children's Research Hospital (SJCRH), retraced the natural avian-to-mammalian evolutionary process of the European avian-like H1N1 (EA) swine influenza viruses that jumped species in the late 1970s.
- Renaturing insects in urban backyardson November 8, 2021 at 2:11 pm
Insects in our environment are unsung heroes. These 'mini-beasts' are often inconspicuous, but they may have a huge impact on the health of ecosystems that sustain humanity.
- Harnessing the ecological roles of animal personalitieson November 8, 2021 at 2:10 pm
Personality differences that account for varying behaviors within species should be taken into account in ecosystem management, according to researchers in the University of Maine Department of Wildlife, Fisheries, and Conservation Biology.
- Managing citrus groves infected with disease by adjusting the timing of their fertilizationon November 8, 2021 at 2:08 pm
Drinking orange juice with breakfast has been a staple in kitchens for years. But a disease has been infecting citrus trees and reducing yields, threatening the supply. Called "citrus greening," it causes trees to decline and die within three years. The disease destroys the production, appearance, and economic value of citrus trees and their fruit. There is no cure.

The prosthetic-tailed dolphin that starred in the "Dolphin Tale" movies may be fighting a gastrointestinal infection, officials said.
- Helping smooth New Zealand sea lions’ road homeon November 8, 2021 at 1:16 pm
A team creates a new way of redefining New Zealand sea lions' habitat. The work will help take the surprise out of coming across sea lions on a forest hike.
- Historical hyperthermal event sheds light on shallow-marine ecosystem collapse and recoveryon November 8, 2021 at 12:28 pm
Around 56 million years ago, Paleocene-Eocene Thermal Maximum (PETM), one of the most famous historical hyperthermal events, led our planet to a super greenhouse condition. It is very important for us to understand how it happened and how it affected the environment, because studying past climatic events of extreme global warmth may be one of the best ways for us to understand and predict future environmental and ecological changes in response to ongoing anthropogenic warming.
- Fish and plant research for future food securityon November 8, 2021 at 12:28 pm
The field of aquaponics has recently yielded a new plant-fish combination. For the first time, a salinity-tolerant plant commonly known as glasswort, or sea asparagus, has been grown together with flathead gray mullet (Mugil cephalus), an important food fish species found in coastal waters worldwide. The experiment was carried out by the Institute of Agrifood Research and Technology (IRTA) at its center in Sant Carles de la Ràpita, Spain, as part of the EU-funded NewTechAqua project.
- ‘Massage breaks the pain cycle’: the return of touch – after almost two years without itby Emine Saner on November 8, 2021 at 10:00 am
For many people, social distancing and lockdowns left them bereft of physical contact. Here, touch experts explain why it is so essential and what we lost in its absenceIn a pandemic that has meant keeping 2 metres away from one another whenever possible, it appears that physical contact is beginning to return. Even handshakes are making a comeback: one poll found younger people were shaking hands again, although older generations are more uneasy about it. “We are wired to respond to emotional touch,” says Francis McGlone, a professor of neuroscience at Liverpool John Moores University. “My analogy is that [touch is] like a vitamin – if we are depleted, there are consequences in terms of our physical health. I make the same argument about the C-tactile afferents – the nerve fibre that evolved in all social mammals to provide the reward associated with close physical contact. When the fibre is stimulated, it does a number of measurable things – it lowers heart rate and it lowers cortisol, the stress hormone.” It’s one reason, he says with a laugh, he believes so many people got pets during lockdown: “That’s the brain recognising ‘I need to touch something’.”For the pet-less, touch-starved, skin-hungry among us, physical contact is a welcome thing. Even before the pandemic, we were living through a “crisis of touch”; perhaps the enforced distance of the past 18 months has made us realise how vital touch is after all. For the people whose jobs rely heavily on touch, it’s been a particularly difficult time. Here’s how they are navigating its return. Continue reading...

A bit of coral shimmers like gold in a US lab as part of urgent work to help the species protect itself from climate change, an effort even skeptical experts see as sadly justifiable.
