Seeing smaller through cells: A natural single-cell biomagnifier for subwavelength imaging

Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both microscopes and tweezers are unable to image and manipulate nano-objects directly. Emerging techniques in plasmonic/photonic nanoscopes and nanotweezers aim to achieve nanometer-scale resolution, although high-index material structures can easily cause mechanical and photothermal damage to the nanoscale biospecimens.

Animals' body sizes shrinking from climate change, study finds

University of Cape Town (UCT) researchers have collected clear evidence—over a 23 year period between 1976 and 1999—that climate change is shrinking animals' body sizes.

How do distance learners connect?

In a typical college classroom, social connections are formed through face-to-face interactions. Through informal chats before and after class, group project meetings, and other exchanges, students are able to build community with their classmates and peers that often enrich their academic experience.

The opioid crisis: Drug overdose deaths are down for the first time in 30 years

Drug overdoses cause more deaths in the U.S. than gun violence, car accidents, or H.I.V. did when they reached their most lethal peaks. For almost three decades, the number of overdose deaths increased unabated. But, according to a recent government report, the U.S. experienced a slight decrease in overdose deaths last year, marking the first decline in drug mortality rates since 1990.

Genetic characteristics of peripheral artery disease

Peripheral artery disease (PAD)—a narrowing of the arteries serving the legs and feet —affects as many as 12 million Americans and 200 million people worldwide. It is a manifestation of clogged arteries, but until now, scientists lacked information about why some people with the disease presented with problems with their legs, some with their heart and some with strokes.

Old vaccine brings new surprises

New research about an old vaccine—one that has been in use for nearly 100 years—has not only shown how effective it is but also suggests it improves our immune response to a wider range of bacteria than originally intended.

New software helps plant breeders bring out their best

Broccoli is in the eye of the beholder. A head of broccoli that might appeal to one person—perhaps because of its deep green color—may leave another cold, due to an asymmetrical shape or too-large buds.

New hard X-ray eclipsing polar identified

Using ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have found that a hard X-ray source known as 2PBCJ0658.0-1746 is an eclipsing magnetic cataclysmic variable of the polar type. The finding, presented in a paper published July 11 on arXiv.org, makes the object one of only a handful hard X-ray eclipsing polars known to date.

Cuttlefish ink found promising for cancer treatment

Researchers have found that cuttlefish ink—a black suspension sprayed by cuttlefish to deter predators—contains nanoparticles that strongly inhibit the growth of cancerous tumors in mice. The nanoparticles consist mostly of melanin by weight, along with amino acids, monosaccharides (simple sugars), metals, and other compounds. The researchers showed that the nanoparticles modify the immune function in tumors, and when combined with irradiation, can almost completely inhibit tumor growth.

Audit: Hospitals put Native Americans at risk with opioids

More ED visits because of alcohol, 175% increase in 25- to 29-year-olds seeking care

New research shows dramatically rising visits to emergency departments (ED) related to alcohol, especially for women, with a 175% increase in alcohol-related visits from young people aged 25 to 29. The article, published in CMAJ (Canadian Medical Association Journal), shows increases in ED visits related to alcohol that are occurring much faster than overall ED usage.

Plasticizer interaction with the heart

Calling an ambulance during an emergency, emailing a breaking news or journal article before a 5 p.m. deadline and maintaining conditions during the fifth week of a 6-week lab study, without altering the light or temperature, requires electricity and translates into time, money and lives. During critical moments, we appreciate the tiny particles and ions in electric currents that power our phones, computers or laboratory equipment. We seldom think about the speed of these connections or potential disruptors when conditions are stable. The same applies to the electric currents, or electrophysiology, of our heart.

Gun ownership linked to greater incidence of domestic homicides

A new study in the American Journal of Preventive Medicine, published by Elsevier, reveals a unique and strong association between firearm ownership and the risk of domestic homicides. For each 10 percent increase in household gun ownership rates, the findings show a significant 13 percent increased incidence of domestic firearm homicide. The homicide risk differed across victim-offender relationships, with nondomestic firearm homicide rising only 2 percent among firearm owners.

More colorectal cancer cases are being diagnosed in younger patients

The incidence of colorectal cancer in adults younger than 50 years of age has increased in the United States since 1970. A new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, found that the proportion of adults diagnosed with colorectal cancer under age 50 in the United States has continued to increase over the past decade, and younger adults are diagnosed with more advanced disease.
