The ins and outs of sex change in medaka fish
A new study by researchers from the Institute of Evolutionary Biology (IBE), a joint center of UPF and the Spanish National Research Council (CSIC), shows that, surprisingly, the distribution of mutations in human tumors is more similar to that of chimpanzees and gorillas than that of humans.
The self-synthesizing ribosome
Scientists could gain insight into atypical sex development in vertebrates, including humans, by studying how nutrition affects sex changes in fish larvae.
Tick-borne encephalitis spread across Eurasia with settlers and their pets and prey
As the cell's protein factory, the ribosome is the only natural machine that manufactures its own parts. That is why understanding how the machine, itself, is made, could unlock the door to everything from understanding how life develops to designing new methods of drug production.
Towable sensor free-falls to measure vertical slices of ocean conditions
Researchers from Sechenov University together with colleagues from several Russian institutes analysed data on the RNA structure of tick-borne encephalitis virus. Much larger than in previous studies, the data volume of the new study allowed them to estimate the age of the virus subtypes and track its spread in Eurasia. The results of the study were published in the journal Viruses.
Tracking the tinderbox: Stanford scientists map wildfire fuel moisture across western US
Towable sensor free-falls to measure vertical slices of ocean conditions.
Tropical forests can handle the heat, up to a point
Researchers have developed a deep-learning model that maps fuel moisture levels in fine detail across 12 western states, opening a door for better fire predictions.
Trust in medical scientists has grown in the US, but mainly among Democrats
Tropical forests face an uncertain future under climate change, but new research published in Science suggests they can continue to store large amounts of carbon in a warmer world, if countries limit greenhouse gas emissions.
UBC scientist identifies a gene that controls thinness
A new Pew Research Center report examines how Americans' confidence in scientists have shifted amid the COVID-19 outbreak and their views on whether scientists should play an active role in policy discussions about science-related topics.
Ultrasonic technique discloses the identity of graphite
Why can some people eat as much as they want, and still stay thin? In a study published today in the journal Cell, Life Sciences Institute Director Dr. Josef Penninger and a team of international colleagues report their discovery that a gene called ALK (Anaplastic Lymphoma Kinase) plays a role in resisting weight gain.
UVA, Peking Univ. and Cal Tech team achieves broadest microcomb spectral span on record
A group of researchers, led by Osaka University, created a high-quality defect-free monocrystalline graphite, and measured the elastic constant, demonstrating that the determined value of monocrystalline graphite was above 45 gigapascal (GPa), which was higher than conventionally believed. Applying ultrasonic measurement techniques to this multilayer defect-free monocrystalline graphite thin film...
Visualization of functional components to characterize optimal composite electrodes
Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborated with Yun-Feng Xiao's group from Peking University and researchers at Caltech to achieve the broadest recorded spectral span in a microcomb. Their peer-reviewed paper, "Chaos-assisted two-octave-spanning microcombs," was published May 11, 2020, in Nature Communications.
We can't (and shouldn't) expect clinicians without PPE to treat COVID-19 patients
Researchers have developed a visualization method that will determine the distribution of components in battery electrodes using atomic force microscopy. The method provides insights into the optimal conditions of composite electrodes and takes us one step closer to being able to manufacture next-generation all-solid-state batteries.
Weight loss surgery may alter gene expression in fat tissue
We can't, and shouldn't, expect healthcare professionals without adequate personal protective equipment (PPE) to risk their lives to care for patients with COVID-19 infection, contends an expert in a stinging rebuke, published in the Journal of Medical Ethics.
Weizmann Institute scientists develop 'sniff test' that predicts recovery of consciousness in brain
New findings published in the Journal of Internal Medicine reveal altered gene expression in fat tissue may help explain why individuals who have regained weight after weight loss surgery still experience benefits such as metabolic improvements and a reduced risk of type 2 diabetes.
When plant pollen scarce, bumblebees biting leaves causes flowers to bloom early
If an unconscious person responds to smell through a slight change in their nasal airflow pattern -- they are likely to regain consciousness. This is the conclusion from a new study conducted by Weizmann Institute scientists and colleagues at the Loewenstein Rehabilitation Hospital, Israel.
Women quotas in politics have unintended consequences
Facing a scarcity of pollen, bumblebees will nibble on the leaves of flowerless plants, causing intentional damage in such a way that accelerates the production of flowers, according to a new study, which reports on a previously unknown behavior of bumblebees.
World can likely capture and store enough carbon dioxide to meet climate targets
Women continue to be scarce in the halls of power. To rectify this inequality, many countries have imposed female electoral quota systems, or rules designed to increase the representation of women. The catch? Boosting gender may well curtail representation in other respects.
'A unique circumstance': Black bear sow with 5 cubs spotted near Penticton
The world is currently on track to fulfil scenarios on diverting atmospheric CO2 to underground reservoirs, according to a new study by Imperial.
Astronomers discover 12.5-billion-year-old disk galaxy
The B.C. Conservation Service is warning people in the Penticton, B.C., area about a black bear sow, recently out of hibernation, with five cubs and it's asking members of the public to keep away from the animals so as to not make them habituated to...
Dead Sea Scroll fragments thought to be blank reveal text
The gargantuan system, which formed just 1.5 billion years after the Big Bang, challenges some of the accepted theories of how galaxies in the universe may have...
Ancient ocean oxygen levels associated with changing atmospheric carbon dioxide
"With new techniques for revealing ancient texts now available, I felt we had to know if these letters could be exposed," the professor who made the discovery said in a...

New insight into allergies could improve diagnosis and treatment
Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold periods of Earth's past? Scientists have been trying to answer this question for many years, and thanks to chemical clues left in sediment cores extracted from deep in the ocean floor, they are starting to put together the pieces of that puzzle.

Chemical recycling makes useful product from waste bioplastic
Results from a new study may help to improve the diagnosis and treatment of allergies, pointing to a potential marker of these conditions and a new therapeutic strategy.

T-cells could be made into better cancer killers by increasing their protein production
A faster, more efficient way of recycling plant-based 'bioplastics' has been developed by a team of scientists.

Researchers have developed a technique to quantify protein production in immune cells known as T-cells, which typically target and kill cancer cells. However, when near a tumor, most T cells produce little protein and lose their cancer-fighting ability, and the new technique could help clarify why. Interventions could then be developed to restore protein production and allow T cells in the...
