Endangered mouse nears ‘zero’ in southern New Mexico

ALBUQUERQUE, N.M. (AP) — Environmentalists are asking for an independent investigation into U.S. Forest Service practices in southern New Mexico, saying hundreds of grazing violations on the Lincoln National Forest have pushed an endangered mouse closer to extinction.

The Center for Biological Diversity in its request pointed to a November report that looked at the condition of the habitat used by the New Mexico meadow jumping mouse, the connectivity between those patches of habitat and how long the tiny rodent has been missing from those areas. The report indicated that the mouse’s population in one stretch of southern New Mexico was near zero.

Robin Silver, a cofounder of the group, wrote in a letter sent last week to Forest Service Chief Vicki Christiansen that local and regional forest officials have failed to issue any noncompliance letters to ranchers who graze in the area despite more than 330 instances in which

Repurposed mouse model sheds light on loss of smell in COVID-19 — ScienceDaily

A repurposed mouse model can develop symptoms of both severe COVID-19 (lung damage, blood clots, abnormal blood vessels, and death) and also of milder disease, including loss of the sense of smell, according to a recent University of Iowa study published in Nature.

The study also showed that convalescent plasma from a patient who had recovered from COVID-19 protected the mice against lethal disease. The findings suggest the K18-hACE2 mouse model is useful for understanding a spectrum of COVID-19 disease symptoms, and for developing and testing new treatments.

When COVID-19 started spreading across the world earlier this year, UI researchers Stanley Perlman, MD, PhD, and Paul McCray, MD, realized that a mouse model they had created a decade earlier to study SARS might be an invaluable tool for understanding the concerning new disease and for testing potential treatments.

In the new study, Perlman, McCray, and colleagues present a detailed characterization

The size of a matchbox, a rare mouse deer is born on camera in Poland

WARSAW (Reuters) – A zoo in Wroclaw, Poland has captured the birth of a tiny mouse deer on camera for the first time ever, in a hopeful moment for the highly endangered species originating from the Philippines.

The baby chevrotain, born on Nov. 10, is the size of a large matchbox and weighs around 100 grams.

The species is characterised by its small stature, spindly legs and mouse-like head, and the birth is of particular significance because there are only a dozen chevrotains in European zoos and just one male.

“For the first time ever in the history of any species of mouse deer, an actual birth was filmed and then the first moment of life of the baby,” Radoslaw Ratajszczak, the head of Zoo Wroclow, told Reuters.

Chevrotains are facing extinction due to hunting and to palm oil plantations in their native home.

“They are very prone to predators…they

Cyber Monday gaming mouse and keyboard deals: the best prices on PC gaming’s prime inputs

With Black Friday behind us, we now look ahead into more deals heading into Cyber Monday and the following week. A lot of online retailers take advantage of this week by basically discounting anything that isn’t nailed down to clear stock. This means there will an obscene amount of mediocre Cyber Monday mouse and keyboard deals. Thankfully, you’ve got us sifting through the dirt to find you nuggets of gold to make sure you don’t spend your holiday bonus on garbage. 

Corsair’s excellent K95 is $70 off right now on Amazon, which we would recommend to anyone looking for a softer sounding mechanical keyboard. Though if you want a keyboard that’s a little more elegant, the Das Keyboard 4 Ultimate seems like something Tolstoy would use. He seems like he would have been a PC gamer.

Black Friday mouse and keyboard deals: the best PC gaming input devices

In 2018, I went on a streak of spilling liquids on keyboards, and ended up replacing and adjusting to multiple decks in a short span of time. After sadly going through some Corsairs (The excellent K95 is $70 off right now on Amazon), I settled on and still use my current all-time favorite keyboard, the Das Keyboard Ultimate, which is currently on sale for $135 for Black Friday.

You’ll notice that the keys on the Das Keyboard Ultimate are completely blank: that’s because it’s a keyboard for jackasses like me who want to show off. Truth be told, even if you’re an excellent typist, blank keycaps can be a little annoying, especially when typing in 2FA numbers and passwords. You can get the same Das Keyboard keyboard, but with labels, on sale for the same price.

Here’s why I like Das Keyboard keyboards: They are sturdy, the big volume knob

Computer mouse movements may reveal appetite for risk-taking

Nov. 24 (UPI) — A person’s proclivity for risk-taking can be sussed out of the subtle movements of a computer mouse, according to a new study published Tuesday in the journal Proceedings of the National Academy of Sciences.

For the study, researchers tracked the movement of the computer mouse as study participants selected between two possible gambling bets, one safe and one risky.

How participants moved their mouse prior to making their selection allowed researchers to accurately predict how the participants would respond to similar risk choices.

The researchers found participants who moved their mouse toward the safe bet before selecting the riskier play were more risk-averse than their choice suggested.

Similarly, participants who nudged the mouse in the direction of the risky bet before playing it safe were found be surprisingly willing to take on risk.

“We could see the conflict people were feeling making the choice through their

Study highlights sex-specific variability in mouse features — ScienceDaily

Scientists have shown that sex-specific differences in variability depend on individual physical and physiological features in mice, debunking competing theories that either males or females are more variable.

The study, originally posted on bioRxiv* and published today in eLife, has important implications for both medical and evolutionary research. It suggests that both males and females should be included in studies, but that statistical adjustments are necessary to account for variation in individual traits among both sexes.

The theory that females are more variable than males because of their reproductive cycles has led to them being excluded from many medical studies, making it difficult to know whether the results can also apply to females. To correct this, many organisations now require females to be included in studies, but this has raised questions about how to account for sex-specific differences in these studies. In evolutionary science, by contrast, scientists commonly believe

Researchers light-up mouse brain, revealing previously hidden areas susceptible to opioids — ScienceDaily

Winding and twisting like a labyrinth, the brain consists of an elaborate network of passages through which information flows at high speeds, rapidly generating thoughts, emotions, and physical responses. Much of this information is relayed by chemical messengers, or neurotransmitters — like dopamine and serotonin.

Although fine-tuned and evolved for complex processing, the brain and its neurotransmitters are vulnerable to hijacking by chemical substances, including opioid drugs such as oxycodone, psychostimulants such as cocaine, and alcohol. Chronic use of any of these substances enhances the activity of a molecule known as the kappa opioid receptor (KOR), which is active in the brain’s reward circuitry. KOR activation produces dysphoria and an inability to feel pleasure. Its enhanced activity following chronic drug or alcohol use plays a crucial role in substance abuse.

KORs have been known to exist in certain brain regions, particularly those involved in pain processing, reward, and stress responses,
