Hit your head, lose your sense of smell

It's long been known that people who suffer a major concussion can lose their sense of smell temporarily and also develop affective problems, such as anxiety and depression. Now scientists have found that's true even for people who get a minor concussion.

Zhang group identifies gene that may make TNBC cells vulnerable to existing

Certain therapies that have proven effective in treating some types of breast cancers are ineffective for women diagnosed with triple-negative breast cancer (TNBC). In fact, there is limited targeted drug therapy for this type of breast cancer—the most aggressive type, diagnosed in about 20 percent of breast cancer patients.

Active pharmaceutical ingredients can persist in the environment

Homeowners who rely on private wells as their drinking water source can be vulnerable to bacteria, nitrates, and other contaminants that have known human health risks. Because they are not connected to a public drinking water supply, the homeowners are responsible for ensuring that their own drinking water is safe.

PrEP use high but wanes after three months among young African women

In a study of open-label Truvada as daily pre-exposure prophylaxis (PrEP) to prevent HIV among 427 young African women and adolescent girls, 95% initiated the HIV prevention strategy, and most used PrEP for the first three months. However, PrEP use fell among participants in this critical population during a year of follow-up clinic visits, although HIV incidence at 12 months was low. The preliminary results suggest that tailored, evidence-based adherence support strategies may be needed to durably engage young African women in consistent PrEP use. The study, known as HPTN 082, was supported by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH), both parts of the National Institutes of Health. The data were presented at the 10th International AIDS Society Conference on HIV Science.

Most women use vaginal ring for HIV prevention in open-label study

In an open-label study of women in southern and eastern Africa, a vaginal ring that is inserted once a month and slowly releases an antiviral drug was estimated to reduce the risk of HIV by 39%, according to statistical modeling. In addition, the study found that participants appeared to use the ring more in the open-label study than in a previous clinical trial. These and other results of the HIV Open Label Extension (HOPE) study were presented today at the 10th IAS Conference on HIV Science (IAS 2019) in Mexico City.

Left eye? Right eye? American robins have preference when looking at decoy eggs

Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg placed in their nest by another bird species—or by a devious scientist.

Finding one's way in the rainforest

Knowing which direction to go in order to reach food or home is important for many animal species, including humans. For human foragers who travel long distances every day for hunting and gathering, orientation skills are essential. Haneul Jang and her colleagues from the Max Planck Institute for Evolutionary Anthropology set out to study how the Mbendjele BaYaka people in Republic of the Congo orient themselves in the dense rainforest. The researchers conducted more than 600 pointing tests with 54 Mbendjele BaYaka men, women and children aged between six and 76 years, in which the participants were asked to point to an out-of-sight target in more than 60 different rainforest locations (including the camp).

Vision scientist says evolution has trained humans to construct reality, rather than to see the world as it truly is

Perception is not objective reality. Case in point: The above image is stationary and flat …just try telling your brain that. In his new book, The Case Against Reality, UCI cognitive scientist Donald Hoffman applies this concept to the whole of human consciousness—how we see, think, feel and interact with the world around us. And he thinks we've been looking at it all wrong.

Warped diffusive radio halo detected around the galaxy NGC 4565

Using the LOw-Frequency ARray (LOFAR), astronomers have discovered a diffuse radio halo around the spiral galaxy NGC 4565. The finding, reported in a paper published July 16 on the arXiv pre-print server, could shed more light on the nature of NGC 4565, disclosing important insights about star-forming activity and the distribution of cosmic-ray electrons in this galaxy.

Scientists discover new chemistry that may help explain the origins of cellular life

Before life began on Earth, the environment likely contained a massive number of chemicals that reacted with each other more or less randomly, and it is unclear how the complexity of cells could have emerged from such chemical chaos. Now, a team led by Tony Z. Jia at the Tokyo Institute of Technology and Kuhan Chandru of the National University of Malaysia has shown that simple α-hydroxy acids, like glycolic and lactic acid, spontaneously polymerize and self-assemble into polyester microdroplets when dried at moderate temperatures followed by rehydration. This could be what happened along primitive beaches and river banks, or in drying puddles. These form a new type of cell-like compartment that can trap and concentrate biomolecules like nucleic acids and proteins. These droplets, unlike most modern cells, are able to merge and reform easily, and thus could have hosted versatile early genetic and metabolic systems potentially critical for the origins of life.
