Why haven't we wiped out rabies yet?
This new NASA Hubble Space Telescope image looks at one of the nearest, massive lenticular galaxies to Earth, NGC 1023 some 36 million light-years away. Lenticular galaxies get their names from their edge-on appearance that resembles a lens. They are intermediate galaxies between ellipticals and spirals. Lenticular galaxies have a large central bulge and a flattened disk like spirals, but no...
How do typhoons trigger coastal algal blooms?
Despite effective vaccines, the rabies virus kills around 59,000 people a year. We asked medical anthropologist Deborah Nadal why the disease is still a threat.

Denying abortion access has a negative impact on children and families
Energy storage with rechargeable battery technologies powers our digital lifestyles and supports renewable energy integration into the power grid. However, battery function under cold conditions is an ongoing challenge, motivating researchers to improve low temperature performance of batteries. Aqueous batteries (in a liquid solution) do better than non-aqueous batteries in terms of rate...
Promoting diversity in reforestation shown to increase productivity
The Roe vs. Wade Supreme Court proceedings in the United States have put the spotlight on the issue of abortion rights. Limiting access to safe abortions has many consequences, including increases in poverty, unemployment and pregnancy-related deaths. Another key area of impact from restricting abortion access is on family well-being and child development.

Diversifying the species in forest plantations has a positive impact on the quality of woodlands, according to an international study involving a CNRS researchers published on May 20, 2022, in the journal Science.
A new tool to verify the geographical origins of virgin olive oil
Scientists from the Max Planck Institute for Plant Breeding Research (MPIPZ) and the University of Cologne, Germany, have discovered a novel biochemical mechanism explaining how immune proteins defend plants against invading microorganisms. Their findings are published in the journal Cell.
Whiteness is at the heart of racism in Britain, so why is it portrayed as a Black problem?
Olive oil is one of the most prestigious agri-foods in Spain and it is the base of the Mediterranean diet. Adulteration and commercial fraud cases occur when it comes to the origin and varieties of a product with such an economic and business interest. Now, a team from the Faculty of Pharmacy and Food Sciences, Torribera Food and Nutrition Campus and the Institute for Nutrition and Food Safety...
Researchers detect a novel binding mechanism between small and gigantic particles
In 2020, two police officers in Hackney strip-searched a 15-year-old Black girl at her school. Police conducted the search of this child, known as Child Q, without the consent of her parents, without an appropriate adult present (despite this being required by the Police and Criminal Evidence Act 1984), and with the knowledge that she was menstruating.
Grim drought outlook for western US offers warnings for the future
Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and a gigantic (in molecular terms) Rydberg atom. The scientists observed the molecule with the help of a self-built ion microscope. The results are published in Nature.
What's it like to be on Venus or Pluto? We studied their sand dunes and found some clues
Much of the western U.S. has been in the grip of an unrelenting drought since early 2020. The dryness has coincided with record-breaking wildfires, intense and long-lasting heat waves, low stream flows and dwindling water supplies in reservoirs that millions of people across the region rely on.
How soaring inflation can be particularly harmful for young people
What is it like to be on the surface of Mars or Venus? Or even further afield, such as on Pluto, or Saturn's moon Titan?
G20 failing to update carbon-cutting pledges: report
Inflation rates have become almost impossible to ignore. In the U.K., inflation has soared in recent months, now reaching 9%—the highest rate for 40 years. The Bank of England expects it to rise to 10% this year and for the economy to slow down.
Collaboration reveals interplay between charge order and superconductivity at nanoscale
Nations in the G20 group of major economies have yet to strengthen greenhouse gas reduction goals despite agreeing to revisit their plans ahead of critical UN climate talks in November, according to an analysis by leading research NGOs seen exclusively by AFP.
Electrons in a crystal found to exhibit linked and knotted quantum twists
High temperature superconductivity is something of a holy grail for researchers studying quantum materials. Superconductors, which conduct electricity without dissipating energy, promise to revolutionize our energy and telecommunication power systems. However, superconductors typically work at extremely low temperatures, requiring elaborate freezers or expensive coolants. For this reason,...
Here's what's come out of US congress hearings on 'unidentified aerial phenomena'
As physicists delve deeper into the quantum realm, they are discovering an infinitesimally small world composed of a strange and surprising array of links, knots and winding. Some quantum materials exhibit magnetic whirls called skyrmions—unique configurations described as "subatomic hurricanes." Others host a form of superconductivity that twists into vortices.
A dazzling Hubble collection of supernova host galaxies
The United States Congress recently held a hearing into US government information pertaining to "unidentified aerial phenomena" (UAPs).
Flow of liquid metals found to exhibit surprising turbulence
Spanning from 2003 to 2021, this collection of images from the NASA/ESA Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurement of Hubble's constant, the expansion rate of the universe
What the new Jurassic Park movie gets wrong: Aerodynamic analysis causes a rethink of the biggest pterosaur
Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth's core, where temperatures are so high that part of the iron is molten and undergoes complex flows. A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now simulated a similar process in the laboratory and made a surprising discovery: Under certain...
Music alleviates collective grief
One of the most exciting moments of the new Jurassic Park sequel, "Jurassic World Dominion," is when the Quetzalcoatlus swoops down from the sky and attacks the heroes' aircraft. With its gigantic wings reaching 10 meters in length end to end, the Quetzalcoatlus was the largest pterosaur that ever existed. However, an aerodynamic analysis led by researchers from Nagoya University suggests that...
'Moth motorways' could help resist climate change impact
In February 2020, a group of musicians from around the world living in China recorded their cover of a song by Michael Jackson on video to express their support to the families affected by the COVID-19 pandemic and to those working in the frontline. The video went viral. Now, in a study conducted by the Department of Psychiatry and Forensic Medicine and by the Institut de Neurociències (INc-UAB)...
