Exposing male crickets to artificial light at night (ALAN) can impair their activity cycles. According to the researchers, nocturnal chirping is the male's way of calling females to come and mate with him, and its disruption can interfere with reproduction processes and even endanger the entire species.
Ventilation matters: Engineering airflow to avoid spreading COVID-19
As we approach two full years of the COVID-19 pandemic, we now know it spreads primarily through airborne transmission. The virus rides inside tiny microscopic droplets or aerosol ejected from our mouths when we speak, shout, sing, cough, or sneeze. It then floats within the air, where it can be inhaled by and transmitted.
Biden launching wide-ranging plan to reduce global methane emissions
The Biden administration on Tuesday launched a wide-ranging plan to reduce methane emissions, targeting a potent greenhouse gas that contributes significantly to global warming and packs a stronger short-term punch than even carbon...
Trudeau calls for global carbon tax at COP26 summit
Prime Minister Justin Trudeau urged all countries of the world to agree to some sort of global price on carbon, a measure he says will dramatically curb the use of fossil fuels and level the playing field for countries like Canada that already impose a levy on...
COP26: Leaders agree global plan to boost green technology
Countries that will sign the pledge cover more than 70% of the world's economy.
Ending Disease review – a powerful case for the miracle cure
In focusing on the stories of recovery this documentary, following patients participating in stem cell research trials in the US, allows the optimism to outshine the controversyHere is a film that tugs at the heartstrings as it painstakingly covers the lives of 10 patients participating in stem cell research trials in the US. From a quadriplegic high-school basketball star to a mother with...
A strategy to control the spin polarization of electrons using helium
Spintronics, also known as spin electronics, is a research field that explores how the intrinsic spin of electrons and its magnetic moment can be exploited by devices. Spintronic devices are promising for a wide range of applications, particularly for efficiently storing and transferring data.
New technique provides detailed information on nuclear material
Whether soil contaminated with nuclear material or archaeological finds: Analyzing isotopes can help determining the age and origin of a sample very accurately. Researchers from Leibniz University Hannover (LUH) and Johannes Gutenberg University Mainz (JGU) have now developed a new technique suitable for obtaining information on the origin of microparticles by analyzing isotope distributions. The...
80% of world economy now aiming for net zero—but not all pledges are equal
More than 80 percent of global GDP—and 77 percent of global greenhouse gases—are now covered by a national net zero target, up from 68 percent and 61 percent last year, according to a new tracker co-led by Oxford Net Zero. But that number shrinks to 10 percent of global GDP and 5 percent of global emissions, if only strong commitments and clear plans are included.
Would a longer school day help children catch up after the pandemic?
COVID-induced school closures in 2020 resulted in the majority of pupils in England—at primary and secondary level—missing around 40 days of school on site. Schools around the globe were similarly affected, though to different extents.
Droughts create fertile ground for cholera; plans are needed to face more dry periods
Africa has a disproportionately high burden of cholera. The World Health Organization reports that between 40 million and 80 million people in Africa live in cholera hotspots. Globally, disease outbreaks have more than tripled since 1980, with 1,307 epidemic events between 2011 and 2017. Cholera was the biggest contributor to this with 308 events.
Heart rate synchronization and palm sweat found to be signs of attraction
A small team of researchers from Leiden University and one with the University of Birmingham has found that when two people are attracted to one another, their heart rates tend to synchronize and their palms sweat together. In their paper published in the journal Nature Human Behavior, the group describes experiments they conducted with volunteers in "dating cabins."
'Perfect for some but disastrous for others': Patients and clinicians express concerns over phone and video consultations

- 21/11/2 14:35
A study of rheumatology patients and clinicians has found that while the majority found phone or video consultations more convenient than face-to-face consultations, they viewed so-called telemedicine as less diagnostically accurate than in-person consultations and as having the potential to increase health inequalities and barriers to accessing appropriate care.

Dwarf mongooses remember which groupmates have picked fights with others during the day and later shun the aggressors during pre-bedtime socializing sessions, according to new research.
Chemo helps breast cancer cells get their ‘foot in the door’ to the lungs
- ScienceDaily

People who are friendly and trustworthy are more likely to be selected for teams than those who are known for just their skill competency and personal reputation, according to new research.
Baby seals can change their tone of voice
- ScienceDaily
- 21/11/2 14:35
Hoover the 'talking seal' famously imitated human speech. But can baby seals already adapt their voices to sounds? Researchers have now studied seal pups only a few weeks old. The pups lowered the pitch of their voice when they heard louder noises. This vocal flexibility makes seals an excellent animal model for studying the evolution of human speech.
New method to prepare diagnostic medical radioisotope
Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have conducted a study on preparation of low specific activity (LSA) 99Mo/99mTc generator, which has potential application prospect for the accelerator/reactor-based production of the medical isotope 99Mo.
How using tree rings to look into the past can teach us about the climate changes we face in the future
"The longer you can look back, the farther you can look forward," Winston Churchill proclaimed to the Royal College of Physicians in 1944, invoking a much older idea known as "uniformitarianism".
Heterogeneous fluorescent organohydrogel proposed for dynamic anti-counterfeiting
The Smart Polymer Materials group led by Prof. Chen Tao at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of Chinese Academy of Sciences (CAS) has developed a fluorescent organohydrogel which can serve as an effective platform for the encryption and decryption of secret information, in cooperation with researchers at Beihang University. The study was published in Advanced...
