Researchers at the University of Tokyo explored how female body odor can influence behaviors in men. They found certain scent compounds in female body odor increased during ovulation and can subtly influence how men feel. When these scents were added to armpit odor samples, men rated them as more pleasant and faces associated with the samples as more attractive. The scents also seemed to reduce stress. The team states this is not evidence of pheromones in humans, but that smell might subtly shape how we people interact. While they’re a common staple of pop culture, especially in romantic comedies, pheromones, behavior-altering ...

UNDER EMBARGO UNTIL 16:00 UK TIME (11:00 AM ET) ON MONDAY 28 JULY 2025 New insights could help phages defeat antibiotic resistant bacteria Researchers at the University of Southampton have worked out how bacteria defend themselves against viruses called phages and the new insights could be key to tackling antibiotic resistance. Phages are seen as a promising alternative treatment to antibiotics. Unpicking how bacteria protect themselves, and how phages might overcome these defences, could be a significant step in defeating antibiotic resistant bacteria. Phages, ...

Cambridge, MA – Scientists often seek new materials derived from polymers. Rather than starting a polymer search from scratch, they save time and money by blending existing polymers to achieve desired properties. But identifying the best blend is a thorny problem. Not only is there a practically limitless number of potential combinations, but polymers interact in complex ways, so the properties of a new blend are challenging to predict. To accelerate the discovery of new materials, MIT researchers ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they simply overlap. Light saber battles, as seen in science fiction films, would therefore be rather boring in reality. Nevertheless, quantum physics predicts the effect of “light-on-light scattering”. Ordinary lasers are not powerful enough to detect it, but it has been observed at the CERN particle accelerator. Virtual particles can literally emerge from nothing for a short time, interact with the photons and change their direction. The effect is extremely small, ...

A new study finds that White students visit academic advisers the least, but have the highest academic benefits, in terms of GPA and graduation rates, compared to nonwhite students and international students. In higher education, substantial gaps exist between White and nonwhite students, with a greater number of White students graduating in fewer years and receiving higher grades than many other groups. Prior research shows that nonwhite students are less likely to engage with faculty members, but there is a dearth of information related to interactions with academic advisers—staffers ...

A frog croaks from a walking trail. A hiker snaps a photo and uploads it to iNaturalist. That single act — one person, one amphibian and one click — feeds into a growing global dataset that scientists now use to map shifting species ranges, detect invasive threats and even discover new species. An international study led by researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) shows how iNaturalist, the global technology platform through which everyday people share ...

UNIVERSITY PARK, Pa. — Though scientists have long understood how lightning strikes, the precise atmospheric events that trigger it within thunderclouds remained a perplexing mystery. The mystery may be solved, thanks to a team of researchers led by Victor Pasko, professor of electrical engineering in the Penn State School of Electrical Engineering and Computer Science, that has revealed the powerful chain reaction that triggers lightning. In the study published today (July 28) in the Journal ...

Hybrid water electrolysis (HWE) is an emerging field that aims to overcome some of the limitations of conventional water electrolysis (CWE) for the production of green hydrogen. In CWE, two reactions take place at each of the electrodes (anode and cathode): one reaction produces hydrogen at the cathode (the hydrogen evolution reaction) and the other produces oxygen at the anode (the oxygen evolution reaction, OER). The concept of hybrid water electrolysis revolves around replacing the anode reaction of CWE (the OER), which is inefficient and requires ...

There is broad consensus that the overall body of evidence shows lowering LDL (low-density lipoprotein) cholesterol provides both statistically significant and clinically meaningful benefits in treating and preventing cardiovascular disease. Often referred to as the “bad” cholesterol, elevated levels of LDL can clog arteries and significantly increase the risk of heart attacks and strokes. In an invited editorial published in the current issue of Trends in Cardiovascular Medicine, researchers from Florida ...

Chronic liver disease (CLD) is a major global health concern, affecting approximately 1.5 billion people. This life-threatening disease often progresses silently, eventually leading to worsened conditions like liver cirrhosis or liver cancer. There is currently no treatment for CLD other than liver transplantation. Vitamin D is commonly consumed for enhanced bone health. This study opens exciting possibilities for repurposing an inexpensive supplement as a complementary therapy for liver diseases. Prof. Hyo-Jung Kwon from the College of Veterinary Medicine, Chungnam National University in Daejeon, Republic of Korea, and his colleagues ...

University research is where innovative technological breakthroughs originate. As a result, a number of proactive universities provide substantial resources and support to their academic researchers to help increase the number of all ventures. However, despite receiving this extensive support and having access to the best scientific knowledge, many academic entrepreneurs are not as successful as their corporate counterparts. While this sounds like a contradiction, there is enough empirical evidence explaining just why this could be happening. With this in mind, Professor Alex Coad from the Waseda Business School, Waseda University, Japan, critically analyzes the differences ...

Consider the delicate web of fat in a Wagyu steak. The “marbling” that makes carnivore connoisseurs swoon is a visual heuristic for quality flavor. Now, a new study suggests the very same marbling of fat inside our own muscles points to trouble. This condition, known as intramuscular adipose tissue, or IMAT, has long been recognized by scientists as a strong indicator of poor health. It’s linked to a wide range of diseases: obesity, Type 2 diabetes, neuromuscular disorders (including Duchenne muscular dystrophy) and neurogenerative conditions such as ALS. In some cases, ...

More than 11,000 additional women opted for the most effective form of birth control—long-acting reversible contraception (LARC)—within just 15 months of B.C. making prescription contraception free. The numbers don’t lie New research from the University of British Columbia and collaborators shows a 49-per-cent jump in LARC dispensations after the province introduced universal, no-cost coverage in April 2023. That’s a seismic shift in how reproductive-aged women are managing their reproductive choice, the researchers say. The study tracked ...

Australian researchers have discovered a promising new strategy to suppress the growth of aggressive and hard-to-treat cancers by targeting a specialised molecular process known as ‘minor splicing’.   Published in EMBO Reports, the study shows that blocking minor splicing can markedly slow tumour growth in liver, lung and stomach cancers, while leaving healthy cells largely unharmed.   The research in animal models and human cells, from Australian medical research institute WEHI, demonstrates ...

Researchers at the University of Michigan have illuminated a complete sensory pathway showing how the skin communicates the temperature of its surroundings to the brain. This discovery, believed to be the first of its kind, reveals that cool temperatures get their own pathway, indicating that evolution has created different circuits for hot and cold temperatures. This creates an elegant solution for ensuring precise thermal perception and appropriate behavioral responses to environmental changes, said Bo Duan, senior author of the new study. "The skin is the body's ...
