Voxelotor improves hemoglobin levels in sickle cell disease
(HealthDay)—For individuals with sickle cell disease, 1,500 mg of voxelotor increases hemoglobin levels and reduces the incidence of worsening anemia compared with placebo, according to a study published in the June 14 issue of the New England Journal of Medicine.

Microscopic glass blowing used to make tiny optical lenses
Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature cone-shaped lenses known as axicons.

Little Raspberry Pi 4 debut marks big upgrade
That credit card-sized computer that has been a standout learning experience for students and hobbyists at affordable cost just stole the show, again. The new Raspberry Pi, announced Monday, "packs significant upgrades that could let it finally pass as an incredibly cheap desktop computer," said Gizmodo's Andrew Liszewski.

Multiresistant intestinal bacteria spread widely in Vietnamese hospitals
Around half of patients admitted to hospital in Vietnam are carriers of multiresistant intestinal bacteria, which are resistant to carbapenems, a group of broad-spectrum antibiotics. This is the conclusion of a study by Swedish and Vietnamese scientists led by Linköping University, published in the Journal of Infection.

How to help physics teachers who don't know physics
A shortage of high school physics teachers has led to teachers with little-to-no physics training taking over physics classrooms, causing additional stress and job dissatisfaction for those teachers—and a difficult learning experience for their students.

Using game theory to model poisoning attack scenarios
Poisoning attacks are among the greatest security threats for machine learning (ML) models. In this type of attack, an adversary tries to control a fraction of the data used to train neural networks and injects malicious data points to hinder a model's performance.

Designing light-harvesting organic semiconductor microcrystals with wavelength-tunable lasers
Organic solid-state lasers are essential for photonic applications, but current-driven lasers are a great challenge to develop in applied physics and materials science. While it is possible to create charge transfer complexes (i.e. electron-donor-acceptor complexes among two/more molecules or across a large molecule) with p-/n- type organic semiconductors in electrically pumped lasers, the existing difficulties arise from nonradiative loss due to the delocalized states of charge transfer (CT). In a recent report, Kang Wang and a team of researchers in the departments of chemistry, molecular nanostructure and nanotechnology in China demonstrated the enduring action of CT complexes by exciton funneling in p-type organic microcrystals with n-type doping.

Setting the standard for machine learning
The microcomputer revolution of the 1970s triggered a Wild West-like expansion of personal computers in the 1980s. Over the course of the decade, dozens of personal computing devices, from Atari to Xerox Alto, flooded into the market. CPUs and microprocessors advanced rapidly, with new generations coming out on a monthly basis.

Why money cannot 'buy' housework
If a man is handy with the vacuum cleaner, isn't averse to rustling up a lush family meal most nights after he's put on the washing machine having popped into the supermarket on his way home then it's more than likely his partner will have her own bank account.

Does limited underground water storage make plants less susceptible to drought?
You might expect that plants hoping to thrive in California's boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years.

Combatting the world's deadliest infections using groundbreaking human-mimetic tools
A new article published today in the journal Frontiers in Cellular and Infection Microbiology shows that research built around human-mimetic tools are more likely to succeed in the search for effective treatments for and prevention of flavivirus infection as compared to research using monkeys or other animals as laboratory models. The study, led by Dr. David Pamies at the University of Lausanne, with researchers at Johns Hopkins University and the National Institute of Allergy and Infectious Diseases' Vaccines Research Center in the United States, includes a comprehensive review of the models used to study deadly mosquito-borne flaviviruses (MBF) such as dengue fever and the Zika virus, known to cause neurological disease in humans.
