LOUISVILLE, Ky. - It is widely accepted that higher levels of body fat increase the risk of developing breast cancer, as well as other cancers. Based on his ongoing research, Bing Li, Ph.D., associate professor in the Department of Microbiology and Immunology and UofL Health - James Graham Brown Cancer Center at the University of Louisville, has published an article which proposes a unique theory that a protein secreted by fat cells drives the development of breast cancer.
Tokyo, Japan - Researchers at Tokyo Metropolitan University have developed a new method to make ceramic-based flexible electrolyte sheets for lithium metal batteries. They combined a garnet-type ceramic, a polymer binder, and an ionic liquid, producing a quasi-solid-state sheet electrolyte. The synthesis is carried out at room temperature, requiring significantly less energy than existing high-temperature (> 1000°C) processes. It functions over a wide range of temperatures, making it a promising electrolyte for batteries in e.g. electric vehicles.
Researchers investigated the group of microorganisms classified as Asgard archaea, and found a protein in their membrane which acts as a miniature light-activated pump. The schizorhodopsin protein draws protons into the organisms' body. This research could lead to new biomolecular tools to control the pH in cells or microorganisms, and possibly more.
NASA's Terra satellite passed over the Southern Pacific Ocean and captured a visible image of extra-tropical cyclone Harold.
Grain boundaries, which are consist of periodic arrangement of structural units and generally recognized as a two-dimensional "phase", can exhibit novel properties that are not existed in the intrinsic bulk crystal. The altered continuity of atomic bonding at grain boundaries cause local chemical environment dramatically change at a few unit cells, subsequently alter local electrical activity, magnetic order or other physical properties.
A world-famous psychological experiment used to help explain the brain's understanding of the body, as well as scores of clinical disorders, has been dismissed as not fit-for-purpose in a new academic paper from the University of Sussex.
The Rubber Hand Illusion, where synchronous brush strokes on a participant's concealed hand and a visible fake hand can give the impression of illusory sensations of touch and of ownership of the fake hand, has been cited in more than 5,000 articles since it was first documented more than 20 years ago.
A technology to further accelerate the commercialization of Colloidal Quantum Dot(CQD) Photovoltaic(PV) devices, which are expected to be next-generation photovoltaic devices, has been developed.
On the 30th (Monday), DGIST announced that a research team of Professor Jongmin Choi from the Department of Energy Science & Engineering and Professor Edward H. Sargent from the University of Toronto has identified the cause of the performance degradation in CQD PV devices and developed a material processing method capable of stabilizing the performance of the devices.
In a wild relative of cultivated wheat, researchers have found a gene, likely delivered through horizontal gene transfer from a fungus, they show, that drives resistance to fusarium head blight (FHB) - an intractable fungal disease devastating wheat crops worldwide. According to a new study, introgression of the newly identified FHB resistance gene Fhb7 in agricultural wheat confers resistance to the disease without a decline in overall yield. The findings suggest a possible solution for breeding Fusarium-resistant cereal crops.
Reframing biosecurity governance as an experimental space, including as relates to handling COVID-19
Biological science and its applications are rapidly evolving, and to keep up with emerging security concerns, governance of biosecurity applications should evolve as well. In a Policy Forum, Sam Evans and colleagues argue for rethinking biosecurity governance - moving beyond assuming the related threats are known, as one major change, and making efforts more experimental. Evans et al. loosely define biosecurity governance as the policies and processes designed to prevent or deter misuse of biological science and technology.
Liquid metals and alloys have exceptional properties that make them suitable for electrical energy storage and generation applications.
Low-melting point gallium-based liquid metals are used as heat exchange fluids for cooling integrated electronics and in the manufacture of flexible and reconfigurable electronic devices and soft robotics.
WEST LAFAYETTE, Ind. -- Bacterial pathogens can live on surfaces for days. What if frequently touched surfaces such as doorknobs could instantly kill them off?
Purdue University engineers have created a laser treatment method that could potentially turn any metal surface into a rapid bacteria killer - just by giving the metal's surface a different texture.
In a study published in the journal Advanced Materials Interfaces, the researchers demonstrated that this technique allows the surface of copper to immediately kill off superbugs such as MRSA.
USC scientists have developed a new battery that could solve the electricity storage problem constraining widespread use of renewable energy.
The technology is a new spin on a known design that stores electricity in solutions, sorts the electrons and releases power when it's needed. So-called redox flow batteries have been around awhile, but the USC researchers have built a better version based on low-cost and readily available materials.

Awareness, Attitudes, and Actions Related to COVID-19 Among Adults With Chronic Conditions at the Onset of the U.S. Outbreak
DALLAS, April 9, 2020 -- Middle age may not be too late for women to substantially reduce their stroke risk by not smoking, exercising, maintaining a healthy weight and making healthy food choices, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
Researchers from Cambridge University and University of California San Diego have 3D printed coral-inspired structures that are capable of growing dense populations of microscopic algae. Their results, reported in the journal Nature Communications, open the door to new bio-inspired materials and their applications for coral conservation.
